A crack team of pilots are selected by the Galaxy Alliance to travel to Planet Arus and uncover the secret of a weapon from ancient times - Voltron! Keith, Lance, Sven, Hunk and Pidge arrive too late, the planet has already been completely devastated by the evil forces of King Zarkon. They engage in battle with Zarkon's general Yurak, only to be captured and thrown into the dungeons on Planet Doom.

Keith and the space explorers take the first steps on their journey to revive Voltron. They find the legendary Royal Castle on the surface of Planet Arus. Inside, they meet Princess Allura and the wise Coran. The Princess declares them to be the planet's new guardians. Together, they unravel the mystery of Voltron's disappearance.

Keith, Lance, Sven, Hunk and Pidge ask for help from the Princess Allura to find Voltron. With guidance from the ghost of her father, King Alfor, they find four of the five keys needed to form Voltron. With no choice, they head into battle with only their robot lions to keep back Doom's soldiers.

The team uncovers the key to the Black Lion, just as King Zarkon's Robeast is about to rain havoc on Planet Arus. Together, they are able to form Voltron's most powerful weapon, the Blazing Sword!

Keith and the team scour the surface of Planet Arus, looking for brave citizens willing to help fight Zarkon. Scared due to the recent attacks, only Princess Allura herself is willing to join Voltron Force. When King Zarkon's best gladiator is turned into a Robeast by Haggar, not even Voltron can stop it. Only if Allura can find a way to help will Arus be saved.

Yurak's attack fleet is soundly defeated by Voltron. Haggar comes up with an evil plan to get Voltron out of King Zarkon's hair for good. She sneaks up to the Voltron Force while they are handing out food to the troubled people of Arus. Haggar isolates Sven from the others and badly wounds him. Without Sven, Keith and the team must face Zarkon's new Robeast without Voltron's power!

After watching the Voltron Force defend her kingdom again and again, Allura is determined to help. However, her Nanny has returned to the Castle of Lions, and is equally determined to keep the Princess out of trouble. When Nanny gets caught up in a raid by King Zarkon, Allura must pilot the Blue Lion to save her!

The mysterious Prince Bocar appears and saves Princess Allura. He seems to be the perfect replacement for Sven as a new pilot for the Blue Lion. But when Lance realizes that Bocar is not what he seems, the evil Prince escapes with the Blue Lion and Allura as his prisoner!

Yurak's fleet shoots down a spaceship over planet Arus. Hunk manages to rescue the pilot, a pretty young slave who escaped from Planet Doom. The Voltron Force is skeptical, but Hunk has faith in her story. That night, the escaped slave breaks into the Castle of Lions' ammunition storage under orders from King Zarkon and plants a deadly bomb!

A girl named Iris was raised as a killing machine by Haggar. Later in Iris teenage years, she travels without Haggar finding the white lion near a small castle in altai.

When Yurak takes a village hostage, the Voltron Force is forced to surrender. A little girl from the village named Tammy sees her mother taken captive along with the others. Trying to get help, she ends up inside the Green Lion. Pidge, in a desperate attempt to save the rest of the team, switches places with Tammy!

After escaping from Planet Nemon, Jai seeks out Princess Allura and the Voltron Force to help save his home. Nemon is under the thumb of Tabor, a nephew of King Zarkon. The evil lord himself has come to celebrate his birthday, but Voltron is coming to crash his party.

Princess Allura's Aunt Orla comes to visit her at the Castle of Lions. Allura's loyal space mice seem to reject Orla, as if sensing something that the others can't. The team becomes suspicious when they spot Haggar's cat attacking the mice, but they can't do anything if the Princess doesn't believe them.

The Voltron Force successfully grounds Yurak's fleet for the last time. King Zarkon is ready to banish Yurak, but then his son, Prince Lotor, returns from his journey of conquest. Prince Lotor turns Yurak into a Robeast, and then challenges Keith to a duel. With Keith away from the team, they are forced to fight Yurak without the help of Voltron!

Princess Allura puts the whole team in jeopardy when she tries to pilot the Black Lion without permission. Seeing no way to make it up to her friends, she surrenders herself to Prince Lotor in exchange for the freedom of Planet Arus. Enchanted by her beauty, Lotor accepts. But Keith and the Voltron Force have a plan of their own.

Arus celebrates the rebuilding of a bridge by reenacting a legend of star-crossed lovers whose devotion to be together let their efforts to unite form the structure. Hunk is all set to perform with Allura after he wins a chance-game to see who will play the male alongside her. However, Lotor attacks for his own personal obsession during the event, and manages to cripple the Yellow Lion once Hunk finally makes it back in after fighting for the lives of both actors.

Zarkon allies himself with King Cova of Pollux, a planet sworn against Arus since they are descendants of an Arusian prince banished for his immorality. His eldest son Avok volunteers to be turned into a Robeast to personally conquer the world he would stand to inherit. Both enemies of Arus plan to betray one another, but Lotor is attracted to Cova's daughter Romelle, who bears a striking resemblance to Allura. Romelle wishes for differences to be settled between the two worlds, and so do the Voltron Force, who approach Pollux in an attempt to prevent war - but they still have to deal with Lotor and the transformed, powerful Avok.

Lotor approaches Haggar's rival Zandra to give him a weapon and is supplied with a potion that will transform plants into monsters, just before Zarkon suffers a terrible disease. Haggar claims the cure is an Arusian fruit. Lotor is reluctant to go, thinking it is trickery, but leaves armed only with his potion when Haggar offers to prove her loyalty by sending armed forces. On Arus, he transforms a group of trees into menaces which terrorize the Voltron Force, intending to take advantage of the situation and capture Allura along with some of the fruit.

Three children discover an unknown castle and choose to look for riches within. Pidge, interested by Coran's story of a similar fortress that held wealth until it was buried so no more wars could be fought among those trying to take its contents, flies out himself and joins the group. Nobody knows it is the work of Haggar's magic until they are trapped in the bell-tower, and the rest of the Voltron Force follow only to be confronted with indestructible fighters - and ships to tow the foundation off when all but Keith are imprisoned as well.

When Pidge's home planet, Balto, is attacked by Zarkon and Lotor's forces, Keith, Lance, Pidge, and Hunk prepare to leave immediately to stop them. When the guys run into trouble in the form of a new Ro-Beast, Keith sends a telepathic message to the Princess. Allura has to decide where her loyalties lie. Should she stay and protect her own home planet, Arus, or should she fly to Balto to save her friends?

Romelle and her fellow captives escape Lotor's prison, but are pursued and forced to crash-land on the frozen world Neve. Both the Voltron Force and her brother Bandor go to rescue her before Lotor arrives, but Allura is nearly tricked by Haggar in disguise. Bandor is tricked and is captured. Lotor orders Allura to give herself up for the lives of her cousins. Keith goes covered in snow as his disguise, but even with that the group still has to think a way around Lotor's attackers to ensure that everyone is actually freed.

Haggar and Lotor send a group of poisoned seeds to Arus which produce handsome plants - which weaken all who pick them for their beauty. Coran and the Voltron Force learn that an antidote is available through a crop of flowers on the magnetically-surrounded Planet Lyra. Allura suggests the underwater-dwelling Blue Lion could fly there since its being used to water would let it through the magnetic field, but she too sickens from a group of the flowers and Lance goes out instead. With the help of a young Lyran named Farla, he tries to get King Mac's permission to harvest some of the plants, but Lotor is waiting with him. He plans to take the plants himself and hold ARus ransom for the sake of their ruler, especially since he knows one of the Voltron Force is dying and another must get past him. Lance loses a duel to him and falls from an infamous wall into a river, but escapes to the Blue Lion, where he must somehow stop Lotor from ruining the crop except for what he'll steal so only he can heal Allura at the cost of Arus - or anyone else.

As Lotor prepares to for another attack on Arus, Allura is forced to work harder on the things she'll be expected to do as a ruler instead of spending leisure-time with the friends she trains with. Trouble occurs when the others in the castle put her safety over her role as a Voltron Force member, and send the other four out without her. They are captured and it is forgotten that her door was locked, so Lotor has nothing to fight against when he attacks her through the window.

Haggar sends a group of small robots disguised as rodents to Arus. Almost everybody is ready to blame the chewed electronics-circuitry on Allura's pets before they themselves are attacked and even more of the castle is damaged. The Voltron Force is forced to battle the creatures who have already ruined the defenses, and another robotic Lotor sends in - without being able to ride the elevators to their Lions to fight.

Zarkon can be seen testing some sort of weapon on Moura, an ally of Arus' now under his control. The Voltron Force set off to investigate. Keith and Lance use the Green Lion's head to approach and disguise themselves as guards. A young man named Haran, who stood against Lotor earlier, reports them. This nearly results in their capture after they find a massive shooting-machine. He is trusted by Lotor for his attempt to see the gun completed in a desperate hope that he will free his people. When the two approach Haran, he reveals that he blames Voltron for their enslavement, since Moura aided them in defense against Zarkon but Voltron was abroad and unable to intervene when Moura was captured. They vainly plead to have him support Voltron in order to see Zarkon's rule overthrown, and are forced to regroup to fight the weapon as well as the powerful Centipede Express Zarkon arrives in.

Haggar uses a spell to grant a powerful robot fighter invisibility. On their way back from the fruit-market, Allura, Lance, Pidge, and Nanny have their carriage forced underwater by it and Allura is nearly captured. The Voltron Force attempt to find a way to defeat their unseen enemy - and even after they bring it into view long enough to note its strengths and weaknesses, they learn the hard way that one of its major benefits is one of their greatest hurdles: water.

Lotor goes to the fume-covered Planet Medusa to arouse and take one of its sleeping inhabitants to fight for him. It turns out to be a monster who can attack with snakes as hair and turn things to stone. The Voltron Force are called away from trying to arrange homes for those orphaned by Zarkon's raid against Arus to fight it. Pidge is forced to eject his struck Green Lion, knocked unconscious, and taken underground by the beast. While the others wonder whether they'll see him again, he is horrified to recover near the creature, but finds the being, Anga, is kind to him. Haggar is determined to turn it evil so it will no longer side against its captors and with their enemy, while Lotor takes advantage of the divided protectors of Arus by sending another menace out. It is up to Pidge to see that no one falls under their power.

Lotor spends his birthday on Tyrus awaiting a shipment of stolen wealth, some of it from Arus' treasury, to deliver to Doom. The Voltron Force notes a distress-call from the neglected ship after an asteroid strikes it and arrive to find the crew out cold, and some of the wealth that they were going to give to charity. Before they can reclaim everything, the ship Lotor sent to collect arrives, forcing four of them to pose as guards and Lance to hide his Red Lion within a golden statue of Lotor. They go to Tyrus planning to attack and take what they can, but are discovered and forced to fight. Lotor plans to celebrate his birthday to ridding himself of his enemies, and Lance must escape where he is imprisoned in a pit with wild cannibals to set the others free.

Haggar creates a Robeast with the ability to exhale flames and emit a magnetic field, which Lotor unleashes on Arus, causing a complete drought. Four of the Lions can take off, but because the Blue Lion uses water as its strength, it cannot fly from the drained lake. Allura must figure out how to fight while grounded, because the others try to hold off the attack as long as they can, but are locked in a suffocating forcefield where they are vulnerable for destruction.

Zarkon decides to have Lotor wed Princess Koral of Demos to unite a similar empire with Doom and she is eager, but Lotor still wants only Allura. Given a sole chance to take what he wishes on his own, he turns to Haggar, who offers him a blade that will put anyone whom it grazes into a coma, mistaken by all others for death. Haggar's cat scrapes Allura with it, and she instantly falls unconscious for hours before appearing to pass away before her friends' eyes. Everyone grieves, but Keith realizes that Lotor would not kill Allura so all must not be as it seems. The four, knowing that Haggar will be responsible for reawakening her after Allura's people bid her goodbye, decide to keep this to themselves as a secret and go ahead with the planned funeral. They try to follow the hearse out, but Haggar causes an accident which makes the driver lose control of the horses. Only Pidge is able to reach it after Lotor has taken it over, and by the time the others fly out to help prepares an attack with Haggar. Pidge is determined to do whatever it takes to save Allura, but thanks to Haggar it may cost someone else's life...

When Zarkon denies Lotor the power of his whole army to attack Arus, Lotor tries to take his power from him by besting him in combat, but fails and acts humble enough to have his life spared. Haggar convinces them to put aside their personal disagreement for the moment since she reveals she's built a Robeast with a frame slightly resembling Voltron's and directed by a robot pilot to conquer Arus. Arus' defense-system is destroyed just after it shows what approaches, and the Voltron Force discover their opponent will not easily be beaten. Voltron is forced to fight while growing weaker and weaker as he is damaged by the strong machine, and the Blue Lion that is the main power-source as his Right Leg faces possible destruction.

With the Blue Lion down, Zarkon encourages Lotor to attack Arus right away. After cryptic message from King Alfor, Keith decides what the Voltron force needs is more training. During the training exercises, Hunk fails to keep the Yellow Lion attached to the rest of Voltron. He starts to question his worth to the team. When the latest Ro-Beast attacks, Hunk asks Keith if he can lead the attack in order to prove himself to the rest of the team.

Haggar creates many miniature-robots disguised as tadpoles to invade Arus since they will thrive in water which Voltron would otherwise not wish to enter. Two siblings collect some to study at home with Pidge's help, and he takes some himself. That night, a group of mutant amphibian-like creatures attack a ship and the children's home. Though they easily destroy the ones in the castle, the Voltron Force's attempt to destroy those out at sea proves more than the usual challenge when a larger robot arrives as well, and damages the Green Lion so Voltron also leaks when formed.

Lotor causes a near-hurricane to strike on Arus, forcing the Voltron Force to go out and round up civilians to shelter in the castle. One boy refuses to go without giving a reason. Since he holds a rabbit, Pidge believes he has stolen it, especially since he says he found it in a trap, which are illegal on Arus. Pidge attempts to fight him then starts to pursue him into the woods - until his own ankle is caught in a snare. The boy, Tommy, releases him before they witness Zarkon's robots poaching. Pidge isn't strong enough to return on foot and when he tries to relay the news through radio, an "earthquake" like one seen earlier destroys it. The divide created by the storm is occupied by something, and the two journey down to examine it. Lotor discovers them and reveals his giant bomb of enough force to destroy all of Arus (except Allura, whom he secretly plans to evacuate). They have no way to contact the rest of the Voltron Force, but to let anyone else know it exists, must escape where Lotor has them bound to the activated weapon.

Arus is set to host the Space Olympics as they are thriving thanks to Voltron. Zarkon and Lotor are too jealous to participate, but plan to take advantage of Haggar's offer to bring down Arus. They place a small robot in the earth-mover that the Voltron Force is using to construct the facilities, planning to use it to destroy the buildings and then the planet. The children helping them are taken hostage within the machine. The Voltron Force are forced to stop the mechanical rampage while keeping themselves and their friends alive as well.

Zarkon blames Lotor for Voltron's continued victories, and commands that he himself, not a robot, take down the Voltron Force. He has Haggar create a stronger and equally-wise duplicate of himself instead, which he sends to Arus. When a Robeast's forcefield disables both the castle's and the Lions' power, Keith swims out to set up a mine to disable it. The clone arrives to fight him with surprising skill. The others hurry to prepare the limited technology they have for him to return, but don't know that he is locked in single combat in which he will have to win before returning to form Voltron, the only thing that will ruin the machine.

While visiting the academy where Lotor trained, he and Zarkon witness a pilot nearly strike them twice while landing. They are eager to meet the daring pilot, Carp, and approach him though he is disliked by the trainer, Morgil. They decide he should be the one to operate Haggar's latest Robeast to crush Voltron. Carp stuns the Voltron Force when he continues to increase his speed until they cannot keep up, even when they use the Lion-heads to aim for him. While he has seen this limitation, they have little time to figure out another way to successfully oppose him when he returns.

Lotor sends Haggar's small human-looking "Red Beret" robots to frighten the Arusians. As planned, the people soon fall into panic, to the point where they blame Allura for not being able to protect them. Lance and Pidge note the volcano that the beings landed near looks as though something is being dug out of it. However, they are called back to the others to restore order before they can discover what is is. They're just in time, though, to see the Red Berets strike by throwing transformed volcanic dust on the Black Lion and paralyzing it. Though this is their last attack, the Robeast following them will make short work of the others without Voltron there to stop them.

Haggar locates and takes control of the Omega Comet, a legendary black-hole-like structure which crushes and destroys anything in its path, and sends it for Arus. Though Voltron redirected it once after a decade of trying, the Voltron Force are forced to race against time to move it themselves after they get Romelle's warning. Seeing Allura's cousin's loyalty to them, Lotor mentions that a certain control-function will help them in front of Romelle, and she relays the information to them. But it was a trap Lotor had her lure them into, and they crash-land and are stranded upon the comet without power. The Galaxy Alliance can send no reinforcements thanks to Zarkon's fighting. But Bandor goes against orders to stop guarding the power-supply he was posted in front of to repay his comrades. The Voltron Force cannot escape, and conclude that Bandor must use his arsenal to strike the comet away from Arus - though they know it means self-sacrifice.

Bandor remains near the Omega Comet, desperately trying to contact the Voltron Force that everyone believes are lost, with no success. Coran, supporting him, is forced to stand alone with his men against Lotor's latest raid on Arus. Coran made it so Bandor's ship, attached to Voltron, actually gains strength through the connection. The tie, however, severs when one of Zarkon's attacking fighters strikes it, resulting in the Omega Comet shooting out of control and Bandor's crew tumbling off alone. The Voltron Force approach the end of the universe, where a mysterious voice offers that they can now enter a place of peace and contentment, but as the price would no longer be able to support Arus...

The one who approaches Romelle after her being forced into the Pit of Skulls is a young, wild-eyed man who warns her of the approaching guards that come down to ensure she is finished, and helps her into a passageway through a cave but then vehemently bids her leave him. She is able to identify him as Sven, but the former pilot of the Blue Lion has lost his faith in himself, feeling remorse over his defeat by Haggar and his inability to aid Planet Ebb when it was attacked when he was hospitalized, and is nearly mad with grief after witnessing so many brutalities every day. Romelle tries to convince Sven to help her get off Doom and contact the Voltron Force so she can return to and defend Pollux as only she knows how, with the help of a group of slaves who are desperate for their own freedom and could be what they need to help them escape...

Lotor sets up on the Sand Planet, with Haggar's plans to transform the thriving, small, pure natives into robotically-charged menaces. Coran's friend, Professor Sarwa, contacts the Voltron Force with the news and calls them to come help just before he disappears on his study-tour there. They meet him and are charmed by the amusing Sand People. But Lotor arrives and uses nature against them to prevent them from taking a group hostage, and transforming them to fight his enemies as well.

Zarkon orders Lotor to conquer a world he has just discovered, knowing that Voltron will arrive with the intention of freeing the people that will be enslaved there. Haggar plans to increase the planet's gravity so that Voltron's actions will be ineffective against her own robotic menace. Four young children are more determined to see their planet freed by whatever way they can and have more belief in Voltron than their parents. They try to take Lotor prisoner but are captured instead. They are used by Voltron's enemies to let the Voltron Force know of the situation after all. However, they are powerless to warn them of the danger that will be faced during the planned rescue.

Yadle, an unattended colony-planet of Zarkon's, declares itself independent and prepares to celebrate along with its allies, the Voltron Force. Haggar creates a Voltron look-alike to subdue its people with Lotor's guards before it will be used to attack the real robot. A young friend named Bobby goes to guide the Voltron Force to Yadle to get through Zarkon's magnetic field. However, they have yet to be warned that they are awaited by a robot that has all their powers and the ability to know what maneuvers they will perform even before they carry them out.

Sven and Romelle learn that Zarkon plans to use a large quantity of lazon for something, so go to spy on him. He selects his five-hundred strongest Robeasts to be sent off to be energized with lazon. The two are able to warn the Voltron Force of this, but in order to prevent the army from being launched against Arus and its supporters, Sven disguises himself as one of the creatures and stows aboard the transport-ship as the only hope of discovering where the factory-base is located.

The space mice are in training for their next encounter with Haggar's blue cat. Pidge gets the idea to even build them their own version of a Voltron Lion. Haggar brings to Arus her newest Ro-Beast, which creates a canyon in the ground. The Voltron Force can't see it, because its hiding in the canyon walls. Suddenly, the Ro-Beast shoots out chains from both sides and captures Voltron. Now it is up to the mice to try and help Voltron save the day.

When Allura, Keith, and Coran call together the rulers of Pollux, Titus, Torus, Yadle, and another planet to plot extended defense against Zarkon, he makes an appeal to the Drule Empire which Doom is a distant part of for support. Without knowing he was rejected, he has Haggar set up a group of impostors as an ally's ambassador-crew and "attacks" them when they land on Arus. During the resulting scouting-mission, Keith invites Allura to use the Black Lion. But Lotor has rigged it to fail and, after a crash, she is forced to run from his last-chance interception and Keith is injured when defending her. Voltron is needed to defeat Haggar's attack, denying Keith any time to recover.

When Allura loses contact on Chemara's moon Cryo while racing back to the castle with the others, a young humble Arusian man named Garrett rescues her. Coran eventually recognizes him as his long-lost son by a pendant he wears, and the Voltron Force welcome him and are set to let him pilot the Blue Lion. But none of them are aware that he is a spy from Haggar, until he locks all who can help the five out of the control-room and works them into a trap where they will be attacked by the stolen Polsar Canon as well as a typical robot enemy.

The Voltron Force decide to disengage at the moment the Polsar Canon will be fired at them (along with the robot they are fighting) so that their enemies will mistake it for a fatal detonation, and end up crashing in separate locations. Those in the castle that are trying to force out Garrett are unsure whether anyone is actually alive so do what they can to defend themselves. Lotor goes back on his word to the clone to let him lead a population of his own on Arus, so Garrett is determined to conquer the planet himself. The Voltron Force eventually find each other and learned what happened to Coran's actual son. However, since the Blue Lion is damaged, they seem about to be forced to try to destroy the solar-powered canon by night without the full power of Voltron.

Zarkon has Lotor arrested for losing battle after battle against Voltron, and attempts to lead a fight himself. But the Voltron Force succeeds in beating him back before he can topple the Polstar Canon. They actually intend to use this canon to boost them out of Arus' orbit to Doom. In this way they can destroy Zarkon's arsenal there to free the enslaved. But Zarkon and Lotor both get a surprise when the Drule Empire hears of the defeat. They're willing to bet that Lotor could do better than Zarkon, and tell him to arrest Zarkon in the same manner when he returns home. Lotor decides it will be a win-win situation if he forces Zarkon to pilot a giant robot to do battle when Voltron arrives...

Voltron is determined to stop Zarkon's reign of terror - which Lotor, who has claimed himself King of Doom, plans to carry on himself. Sven, Romelle, and their group of followers are just as set on freeing those they witnessed suffering in slavery. They work to slowly destroy everything that has been used to torture them. But though their enemies find themselves divided from within on almost every level, the Voltron Force still must face a major threat: Zarkon is eager to defeat them, even in the humiliating circumstances of being forced to fly a large robot likeness of himself.

The Voltron Force and their allies prepare to take down Castle Doom, the last of Lotor's defenses. But Voltron is nearly destroyed before they can actually land, until Coran pilots the Castle of Lions in its spaceship form to support them. With Haggar having parted ways with him, Lotor's downfall seems definite. But in trying to make certain that his tyranny will never rise again, Sven is drawn into a trap. He is held at ransom, to the horror of all his friends, and has the seemingly impossible job of trying to find a way to stop Lotor from melting their beloved robot before their eyes.

With Earth and its allied worlds suffering from dangerous levels of overcrowding, Galaxy Garrison sends the Stellar Ship Explorer into the Near Universe to search out new worlds. However, doing so brings them critically close to the evil Drule Empire. For protection, they develop 15 exploratory spacecraft using an ancient super-technology and train their pilots with the secret of assembling Voltron.

The Stellar Ship Explorer has landed on a new planet and is preparing to set up a permanent base. Drule fleet commander Hazar has gotten word of this plan, and has decided to capture the planet and the Alliance facilities in one fell swoop. However, his assistant Captain Quark gets impatient, and launches a full-scale assault while Jeff and the rest of the Voltron Force are busy scouting the planet.

Hazar issues an ultimatum to the Explorer and her crew vacate the planet or he will obliterate it. Jeff, Cliff, Krik and the rest of the Voltron Force try to stop them, but the planet is too fragile and begins to explode. To escape the doomed planet, the Land, Sea and Air Teams must combine to form Voltron while under heavy attack from all sides.

Krik's sixth sense leads the Stellar Ship Explorer to a strange black hole cluster. A faint distress call convinces Commander Hawkins of the need to investigate, so he sends in the Sea Team. However, the entire team is soon lost in the Sea of Holes, and there they encounter an enormous Robeast! As Jeff rushes to the rescue, Krik wonders if his sixth sense has doomed them all.

Cliff and his Land Team are sent to explore a seemingly barren planet. The crew are surprised to discover strange vegetation in several areas of the planet, each patch near a crashed rocket. Ambushed by hidden defenses, the Voltron Force rushes into battle. Meanwhile, Hawkins realizes that the planet is already being terraformed by the Drules, and this time the humans are the invaders.

The Explorer is caught in a terrific storm of meteors, and is badly damaged. Captain Mongo of the Drule Empire moves in to take advantage of the situation. Jeff and the entire Voltron Force don space suits to help with the repairs, desperate to finish before the enemy gets to them. But Mongo has an even bigger trap in the works, one that could destroy the fleet.

Galaxy Garrison decides to send the Explorer into enemy space to try and make peace. Giving their word that they will not use Voltron, Hawkins and his crew approach the Drule Empire. To keep them safe, they are escorted by Commander Kio and his squadron. When Kio's squadron is ambushed by the Drules, our heroes disobey orders to go and save him.

The Explorer arrives at a new planet, only to find a strange Ghost Fleet appearing and disappearing around the globe. Intrigued, the Voltron Force begins a wild goose chase as the Explorer waits in a central lake. Hawkins has a bad feeling that the planet holds a terrible secret, but will they figure it out before the Ghost Fleet strikes?

Working around the clock, the crew of the Explorer is at the point of collapse. Captain Newley and Commander Hawkins have no choice but to set down on a nearby planet and give everyone shore leave. Meanwhile, the supply convoy they are scheduled to meet up with is ambushed by a Drule attack!

Cliff and his Land Team find an ancient city on a forgotten planet. While exploring, Cinda and Modok find an army of strange bats. Modok goes berserk before finally collapsing, burning up with fever. It seems the bats have given him a strange virus. Then the Drule fleet attacks, but without Modok our heroes cannot form Voltron!

A young Drule pilot crashes during training exercises and is saved by Jeff and the Voltron Force. Nursed back to health, the pilot begins making friends. Newley and Hawkins think that the Drule pilot could become an emissary of peace. However, Sea Team member Shannon has a brother who is a POW, and being friends with a Drule doesn't sit well with him.

The forests of a dead world reminds Wolo of his childhood, growing up with his brother on a faraway planet. As he remembers when his brother was seriously hurt saving his life, an earthquake puts him in immediate danger. Without his brother to help him, Wolo must act on his own to save himself, and the entire Voltron Force.

As the Explorer approaches the deadly planet of Itlon, they receive a mysterious distress signal. Risking their lives, the Voltron Force descends to the planet only to find the evil Nerok and his attack fleet. They are sitting in the middle of an electrical storm, and seem to be in trouble. Are they disabled, or is this Nerok's most risky trap yet?

A mysterious comet passes very close to Earth, causing the populace to panic. Seemingly under the influence of the comet's strange radiation, General Steel orders the Alliance ships to stage a pre-emptive strike on the Drule Empire. Unfortunately, the Drules predicted this effect and are lying in ambush.

Commander Hawkins finally convinces the Drule Empire to engage in peace talks. Bravely going to Captain Mongo's ship alone, he convinces the Drule leader of his good intentions. Before they can finalize a plan for joint exploration of space, Brak decides to use the peace talks as a distraction to launch an attack on the Voltron Force.

An uneasy peace has been established between the Alliance and the Drule Empire. But Galaxy Garrison is unable to reach a consensus in time, and a local fleet commander refuses to withdraw from a Drule planet without official orders. If Hakwins and the Voltron force don't convince him to leave, they'll be in violation of the truce.

Infighting among the Drules makes it impossible for them to make a move for either peace or war. On the Explorer, the crew gets surprise news as they try to meet up with the Drule for peace talks. Captain Newley is being transferred to Galaxy Garrison headquarters. It is an honor, but the captain has many important friendships he will be leaving behind.

After countless false starts, the Voltron Force finally begins joint explorations of new worlds with the Drule Empire. However, Nerok calls in a favor with the Imperial Council and manages to get command over the peace effort. His first order to the exploration force is to forget the peace effort and prepare for attack!

The Voltron Force discovers signs of an ancient civilizationon planet Neb. However, the planet is unstable and Nerok isright behind them, ready for an ambush.

The Explorer and the Voltron force are in bad need ofadditional funds to continue their operations. Steel andNewely appear before the Alliance council to get moresupport for the Explorer program. They also explore theoption of building yet another Voltron Unit. Back on theExplorer, the team trains to be stronger for their nextencounter.

Marshal Keezor brings news that Hazar has been demoted,and Nerok is finally given permission from the Drule councilto go on the offensive. He immediately orders Mongo, one ofthe few Drule commanders who still agrees with Hazar, toattack Voltron's support fleet. Despite his misgivings, adirect order gives Mongo no choice.

Mongo is forced to launch an attack on the Alliance againsthis wishes. The Alliance fleet commander decides toconcentrate all fire on the flagship, in hopes that the fleetwill retreat if their commander is lost.

Hazar returns to planet Drule to try and convince highcommand to make peace with the Alliance, and plead hiscase against allegations of treachery. Despite help from hisfather and his sister Dorma, he is attacked by a mob ofcitizens, and then sentenced to exile on planet Dreska. Inhonor of the efforts he made for peace, the Voltron Forcedecides to name the planet he saved "Hazar."

The empire takes full advantage of this, sending a fleet to Earth to stage a direct attack on Galaxy Garrison high command! The Voltron Force can only watch helplessly as enemy shipsbombard Earth's surface directly. Carver's fleet rushes to help the Explorer, so the energy system can be repaired.

Jeff and the Voltron Force are sent to attack a Drulecommand base, but it's well protected by an impenetrableasteroid belt. In addition, the enemy has set up a field ofspace mines. Luckily, before Voltron can fly into the trap, oneof the Drule commanders becomes impatient and launches apre-emptive strike. Jeff takes the chance to disrupt theDrule's plans. It won't help if he can't get past the asteroids.

Jeff, Krik, Cliff and the rest of the Voltron Force are campingon a new planet while the Explorer is down for repairs. TheDrule Empire sends a fleet after them, jamming theircommunications and attacking. Krik and Cinda are separatedfrom the others, so forming Voltron is impossible. TheExplorer is pinned down and even Hawkins is ready to admitdefeat... until the arrival of an old friend!

As Hazar makes another desperate attempt to arrangepeace between the Drule Empire and the Alliance, the Drulecouncil sees this as an excellent way to trap Voltron. Settingup a fake peace conference, they ambush the Air Team whenJeff flies his men in to scout out the meeting place. Jeff'steam ends up trapped in a cavern, and the entire planet isset to explode!

A series of letters from home reaches the Voltron Force,and for some reason this sends Chip into a deep depression.The Voltron Force needs to mobilize, but Chip is nowhere tobe found.

After being caught, Papa Mouse promises that his children will stop swiping food if they let them go. Later that night, the cat turns into a saber-toothed tiger. The tiger lets Haggar's blue cat into the castle, and they proceed to wreck the control room. The cats also capture Cheddar, and escape. The Voltron Force follows after them in hope of saving their little friend.

What seems like another peaceful day on Planet Arus is interrupted by another Ro-Beast attack. The Voltron Force race to the scene to protect the people. The monster traps Pidge and Hunk in its claws, releases some kind of foam that traps Keith and Lance, and knocks Allura out of the sky. The top of the Ro-Beast splits open revealing a second Ro-Beast, which goes to attack the Castle of Lions, leaving only a shell behind. The Ro-Beast invades the castle and traps Nanny and Coran in the control room. Allura gets the Blue Lion working again, and rushes back to the castle to rescue them.

Lotor, Cossack, and Haggar invade Planet Zal in order to mine its supply of lazon, which is an ingredient they believe will make their Ro-Beasts stronger. Joran, a former soldier for Zarkon and now a slave, gets into a fight with other slaves over his being a traitor. He falls over a cliff, but is saved by Omnia, the leader of the people of Zal, who has been hiding underground.

The pilots are captured by Cossack, but the jungle woman manages to get an injured lieutenant to safety. The Alliance learns of the crash and summons the Voltron Force to come to the rescue.

On the way home from their latest mission, Hunk spots a planet that is home to some friends of his. He had met these kids on one of his first missions right out of the Space Explorer Academy. Hunk decides to take a vacation and visit them. Haggar and Cossack see a golden opportunity to isolate the Yellow Lion. They arrive on the planet and take the kids hostage. Cossack gives Hunk and ultimatum: Hand over the key to the Yellow Lion, or the kids have had it!

A spaceship crash lands on Planet Pollux appearing to be filled with slaves trying to escape from Planet Doom. Sven and Bandor take them back to the castle for medical treatment. Romelle encounters one patient wearing a mask. She tries to get him to remove it, but he refuses. Bandor tells Sven that his house is on fire. Sven rushes home to find Witch Haggar waiting for him. He also discovers that the masked man and the other slaves were actually sent by Prince Lotor, and have taken the castle hostage. Haggar plans to use Sven to set a trap for the Voltron Force.

The Voltron Force meet Mary Ann, who Coran said was the greatest robotics scientist in the universe. Zarkon's forces have taken one of her robots and turned it into a weapon for evil. Mary Ann, who is a pacifist, gets into an argument with the team over whether or not violence is ever the answer. As she heads for her home planet, Caspia, Keith and the others fear she may be walking into trouble, and decide to follow her. Their suspicions turn out to be right as Haggar and Cossack are waiting. Pidge finds Mary Ann first and provides her with cover fire so she can get away. Haggar then captures Pidge and wants to exchange him for Mary Ann and her robotics knowledge.

The Galaxy Alliance contacts the Voltron Force when it learns that one of its members, Planet Oron, intends to leave. Oron has a new leader, General Kruger, who has built up a stockpile of weapons and therefore doesn't see the need for the Alliance or Voltron. The Voltron Force arrives on Oron to meet with Senator Roland, who wants his planet to stay in the Alliance. Kruger has ordered Roland's arrest, and announces that he has formed an alliance with Planet Doom. After a brief skirmish, Kruger orders the Voltron Force to leave. As soon as they're gone, Cossack takes over Oron, and makes everyone slaves. Roland and some rebels sneak into a radio room, and beg Voltron to please come back.

Zarkon has formed a new alliance with Largo, leader of the Rogue Galaxy, and they have started taking over the universe. An emergency meeting of the Galaxy Alliance is called. During the meeting, there is an attack, and the Voltron Force heads out to join the fight. Coran and the other leaders are captured by Lotor, Haggar, and Cossack. Sven manages to slip away. Lotor parades the leaders outside and gives the Voltron Force an ultimatum, turn themselves in or else. As Keith is coming out of the Black Lion, he sees Sven and some guards on the rooftop. They open fire, and during the confusion all five lions take off, but they get a call from Allura that she's still on the ground. So they ask the question, who's flyin' the Blue Lion? As it turns out to be Sven himself.

Zarkon enlists the aide of Stride, a legendary Tiger fighter, in his battle against Voltron. Stride wants no part of Zarkon's personal grudges, so Zarkon falsely claims that Planet Arus has challenged Stride's honor. As Stride leaves to fight Voltron, Zarkon welcomes a new ally, Queen Merla. After hearing of Zarkon's plan, Merla decides to head to the battle sight, because she doesn't want Zarkon getting all the credit. Stride meets Keith in a one-on-one fight. Keith earns Stride's respect by fighting valiantly, which leads to Merla attacking both of them.

Merla uses her telepathic powers to make Zarkon place her in charge of the next mission to attack Planet Arus. Meanwhile on Arus, word has been spreading that King Alfor is preparing to return from the grave. Some townspeople find a cave that has a statue with a golden shield that is believed to have belonged to Alfor. Allura, wanting to believe that her father has returned, heads for the cave with her teammates right behind her. It turns out to be a trap. The guys get trapped in the cave, and Allura gets taken prisoner by Merla.

Zarkon oversees the wedding of Lotor and Merla. He sees the wedding as the way to unite their two evil kingdoms. Meanwhile on Planet Arus, a young woman named Taryn pines away for her lost love, Ro, who was taken as a slave to Planet Doom. Ro shows up with two mystery women, Merla and Haggar in disguise. Merla claims to have a crush on Keith, and in exchange for bringing Ro home, she wants Taryn to deliver a jar of fresh honey to the castle as a present for his birthday. Taryn gives the jar to Allura, who ponders her own feelings for Keith. After Taryn returns, Ro reveals that the jar actually contains poison. Now they have to get to the castle and warn the Voltron Force before any of them drink it.

Haggar tries to send a baby Ro-beast after Queen Merla, but Merla's pet buzzard catches it. Haggar apologizes, and offers to help Merla conquer Arus. Meanwhile, on Arus, there is a parade taking place honoring the planet's leaders. Merla's forces attack. Keith and Allura try to get the villagers to safety, while Lance, Hunk, and Pidge race to get to their lions. In protecting the villagers, Lance, Hunk, and Pidge get zapped with a freeze ray, and their lions are sent over a cliff, and to the bottom of a canyon. After getting the villagers to the castle, Haggar makes her baby Ro-beast turn into a full sized one, and sicks it on the castle. With the other three frozen, Keith and Allura have to face the monster by themselves.

Philos, a half planet and half comet, is getting ready to pass by Planet Arus for the first time in 52 years. Philos has been taken over by Lotor, who has been having the slaves build a monument to Allura. Zarkon tries to have his son arrested for disobeying him, but then Lotor shows him a new weapon to destroy Voltron and conquer Arus with, the Herculean Generator. Meanwhile, Count Zane of Philos arrives on Arus, and informs the Voltron Force that Zarkon now controls Philos, and has the Generator. They also get a distress call from the Galaxy Alliance that one of their ships has crash landed on Philos after a battle with Queen Merla. Zane offers his services, and everyone except Lance is ready to accept his help. Lance thinks that Zane is leading them into a trap.

Lotor tries to attack Zarkon from behind. Zarkon catches him in the act, and orders his arrest. Meanwhile on Arus, a young woman asks the Voltron Force for help for her sick mother. Her mother had come upon Haggar, and the witch responded by casting a spell to make her ill. Allura gets a vision from King Alfor's ghost telling her that the way to break the spell is from a magic cadmium flower. When the flower blooms, Haggar sends her blue cat to steal it. The team follows her to Planet Pollux, where they find out that Zarkon is building a secret military base. When the Ro-Beast attacks, the Voltron Force is aided by an unlikely ally.

Princess Romelle is visiting Allura on the day of King Alfor's Eclipse. While his sister is away, Prince Bandor gets a call from the Galaxy Alliance that Queen Merla has been captured by the Muses of Norn, but they will only turn her over to someone of rank. Bandor confronts the Muses, and their leader turns out to be Haggar in disguise. Lotor also arrives, and destroys Bandor's fleet. The Voltron Force flies to the rescue. Lotor tricks them into chasing him into the sun of Norn. He then escapes through a space warp, and leaves them to fight Haggar's latest creation, a Firebird Ro-Beast.

All over the universe, members of the Galaxy Alliance are rising up and striking back against Zarkon's forces on their planets. The Voltron Force decides that now is the perfect time to strike Planet Doom and stop Zarkon once and for all. Zarkon once to leave in his Doom Ship and face them himself, but Lotor steals the ship and wants to take the glory for himself. Zarkon takes over the ship by remote control and decides to ram it into Voltron. Queen Merla saves both Voltron and Lotor, but in the process Lotor is taken captive. Merla approaches the Voltron Force, and asks for their help in saving Lotor.

After recharging the Lions back on Arus, the Voltron Force heads back to Planet Doom to challenge Zarkon. Merla convinces Lotor to try being good. Merla and Lotor decide to help the Voltron Force. Zarkon's robot troops bring a group of slaves, and threaten to hurt them unless Voltron surrenders. Lotor sees through the deception, and hurls his sword at one of the slaves. The slaves are revealed to be more robot troops in disguise. Lotor leads the Voltron Force to Castle Doom, where they confront Zarkon in the throne room. The Voltron Force is caught in a trap with a Tentacle Bomb. Now they must escape before the entire planet blows sky high.

In his attempt to destroy the Galaxy Alliance, King Zarkon allies himself with Viceroy Throk of the Drule Supreme Council to create a mighty armada known as the Fleet of Doom. To stop Zarkon, Keith and his friends combine forces with their friends from the other Voltron Force. Unfortunately, Haggar captures Princess Allura, leaving only Keith to rescue her from the evil witch. But to save Allura, Keith would have to travel to a land beyond space and time, where he must face Haggar at her source of power.

Years ago, the Voltron Force defeated Prince Lotor, resulting in his horrible disfigurement and Voltron being retired. But before Lotor was captured, he sent Castle Doom away to an unknown location.

In the present, Keith, Princess Allura, Amalgamus and the seemingly reformed King Zarkon are trying to learn from Lotor where Castle Doom went. Meanwhile, space pirates have reemerged and begun attacking Galaxy Alliance ships and colonies. Lotor has escaped, using a hologram as a decoy.

Lance disobeys orders from Amalgamus not to activate the Robot Lions to investigate Lotor's escape. Lotor is building a new generation of Doom Weapons, requiring pure quartz, ionized topaz, moonstone, and condensed lason. Lance gets captured by Lotor and the rest of the team arrives to save him and defeat Lotor.

Lotor fakes a peace summit with King Zarkon after raiding a planet. It is revealed that Lance's village got destroyed by King Zarkon when he was a boy, hence he is more keen to take agressive actions against Zarkon and his son Lotor. Lotor enters the Dream Dimension to retrieve Haggar and Doom Castle. Princess Allura obtains the Lion Paw and the team enter the Dream Dimension with it. The team forms Voltron and defeat Lotor's robeast.

The team is summoned to Galaxy Garrison after the peace treaty "broke down". The pilots are suspended and replaced by drones for their part in the failure. The Robot Lions are activated by Amalgamus with their new drone pilots to respond to a new attack by Lotor. The Lions are unable to form Voltron, and Allura believed that they need human pilots, as the Lions are more than just machines. The team take over the drones and defeat Lotor.

Lotor plants a mutation bomb in the mines of Planet Geo. Voltron Force responded to the scene with an order to stop Lotor, and they destroy the mining infrastructure in the process. The team is summoned to Galaxy Garrison, where they are decomissioned, when Amalgamus denied sending any order, as Lotor was ready to negotiate for peace and their defence was viewed as an unprovoked attack. The team is sent to Planet Geo to repair the infrastructure, but the ship is destroyed by space lice. Working together, they improvise an escape craft back to Planet Arus, where Allura saw a vision with the Lion Paw that Haggar is in the Castle of Lions to steal the secrets of the Lions. The team arrive in time for Lotor to fire upon the castle in an attempt to intercept them, prompting Haggar to flee before uncovering the secrets. It is revealed that the initial order to stop Lotor is sent by Zarkon. The team forms Voltron and defeats Lotor.

Hunk leaves Planet Arus after one tease too many by Pidge. He gets captured by Haggar who turns him against his team, and turning his Yellow Lion grey in the process. Zarkon sneaks a robeast disguised as Hunk to Amalgamus, and kidnaps him. By Allura's bravery, Amalgamus is rescued, and Pidge breaks Hunk out of Haggar's spell by apologising to his best buddy, when Hunk pinned him down and was going to kill him. The team forms Voltron and defeats Lotor, who again flees the scene.

Lotor and Haggar kidnap Judge Armistice in a plot to get Allura to marry Lotor. Haggar casts a spell on Lotor to make him handsome again, but only to Allura. The team launches to fight Lotor and rescue Judge Armistice, but Allura gets distracted by a light she believed to be Castle Doom, and cannot contact the team as her communications are blocked. Allura investigates the light, but discovers Judge Armistice is held hostage and she must marry Lotor for the Judge to be released, as Judge Armistice is needed in the signing of a peace treaty to prevent intergalactic war. Allura communicates with Blue Lion telepathically to send a distress signal to the rest of the team, and stalls to buy enough time for them to respond. The team arrives just in time for Allura to escape with Judge Armistice, and forms Voltron to defeat Lotor.

Lotor uses the radiation on Planet Geo to mutate an egg. The egg hatches into a giant antimatter-spewing lizard called Dominus, and wrecks havoc on the planet and the team. He eats a moon with antimatter and falls asleep. The team come up with a plan to take down Dominus by making it attack Haggar's ship. This causes Haggar to shrink Dominus back down again.

Lotor and Haggar tame 4 dragon robots and intend to release and tame the fifth one, Draco. Draco was a powerful dragon and took much efforts for Allura's ancestors to tame and chain in the past. Lotor and Haggar release Draco, but fail to tame him. Draco forms Dracotron with the other 4 dragons, and think Lotor and Haggar are the ones who imprisoned him. Lotor begs Allura to save them, and the team fights Dracotron.

Keith catches Zarkon colluding with Lotor, but has no documentation of it as proof. Zarkon discovers Keith's spying and informs Lotor of that. Lotor then tells Haggar, who strikes Black Lion with an attack while they are trying to form Voltron. Haggar then casts a spell on Keith, causing him to think he is a lion. After failing to find a cure, the team mobilizes to face an attack by Lotor. Keith gets into the cockpit of Black Lion, and the lion spirit heals him. Having recovered, Keith joins the rest of the team and forms Voltron, and defeat Lotor.

Hagar traps King Alfor's spirit inside a Crystal Robeast. When the Alfor Robeast disables the Robot Lions in battle, Allura tries to free her father's spirit and faces the Robeast unarmed.

Pidge goes to Planet Glacia to examine the Alpha-Ice, the coldest matter in the universe. When Zarkon employs a new Battle-Borg named Igor to freeze Pidge and Green Lion it is up to the Voltron Force to save him and find the Alpha-Ice.

Amalgamus proposes to the Galaxy Garrison High Council that the Voltron Force be permanently disbanded. With some members of the council in favor of Voltron, what will its ultimate fate be?

Amalgamus goes to the Galaxy Garrison High Council and argues that the Voltron Force be permanently disbanded. When other members of the High Council come to Voltron's defense, the most exciting adventures of the Voltron Force are retold in flashbacks.

While transporting Dominus back home Lotor attacks the Voltron Force. A new robeast attacks and the Voltron Force must rely on Dominus to save them.

Allura learns that the Robot Lions are made of the "spirit" of real Lions who once lived on Arus and have sworn to protect it. Calling on the spirit of the Lions, the Voltron Force makes one last stand against Lotor.

The Voltron Force learns to use telepathy to control their lions. Pidge, not being any good at mental telepathy, resists and is captured by Zarkon and Lotor. The Voltron Force must use their new powers to save Pidge.

The Voltron Force get control of Amalgamus and fix him. He becomes the strong, supportive leader he always should have been.

After Voltron's victory over Lotor and his army, the Robot Lions lost control during a celebratory event and nearly destroyed a city. Because of this, Galaxy Alliance commander Sky Marshall Wade ordered the Lions to be dismissed from their duty as defenders of the universe and disbanded the Voltron Force. Since that day only the Galaxy Alliance has been in charge of protecting the universe while Lance, Pidge, and Hunk are acting officers in the army, Princess Allura is ruling her home planet Arus, and Keith is a fugitive from the Alliance. Daniel is a mischievous and curious student in the Galaxy Alliance air school. Daniel and fellow student Vince are recruited into the Voltron Force as junior cadets and later become members of a resistance against Sky Marshall Wade, during which Keith infiltrates Wade's secret base and searches for the Black Lion. Now, as part of the resistance's plan, Daniel and Vince sneak into Wade's room and switch out his prized pin with a fake one and head back to "The Den", the resistance headquarters. The reason is that the four insignias on the pin are actually the keys to reactivate the Lions. Meanwhile, Keith discovers his Black Lion and breaks it and himself out of the base, contacting Pidge and trying to escape Wade's security.

Daniel and Vince arrive at the Castle of Lions and meet a fellow Cadet named Larmina, who is revealed to be Princess Allura's niece and the trio are given their "Voltcoms", special gauntlets that access special abilities within them and will allow them in the future to pilot the Lions. As Pidge and Hunk go to rescue Keith from drifting into space (due to the fact that Wade's experiments on Black Lion have left it barely with any power), Kala, a Drule commander/strategist, and Maahox, a scientist, succeed in bringing Lotor back to life. They explain how long he has been gone and the changes that have been made to his army, and send a Robeast to Arus to battle the Voltron Force. Lance and Allura realize that they must fight it without the other three Lions. When the fight gets too much for Lance and Allura, Daniel and the others get to the Green (Vince and Larmina) and Yellow (Daniel) Lions to help fight off the Robeast alongside Lance and Allura, but even that proves to be not enough to turn the tide. Pidge and Hunk save Keith and send him into Arus' atmosphere to crash land on the planet, accidentally decapitating the Robeast and destroying it. As Lotor watches in anger, Kala and Maahox explain how the same Robeast was from his time and the beasts are not enough to defeat the Voltron of today.

After the previous events, Wade goes insane and kidnaps the Alliance and replaces its soldiers with robots, while additionally holding Coran hostage. Meanwhile Lotor and Maahox plot to send a new Robeast to Arus to destroy Voltron as it is powered by a combination of Kala, the Drule commander that Maahox terminated and Haggarium, the substance that Kala's energy apparently stabilized and was used to resurrect Lotor. As the Lions fight the Kala Spider Robeast (with Daniel piloting the Red Lion along with Lance due to an injury he sustained), Keith and Larmina fend off Wade's robots on the ground and Vince works on fixing the Black Lion, Wade (on another planet with Coran as his hostage) sends a massive Robot Lion to battle both the Voltron Force and Kala. At one point the Kala Robeast absorbs the power of Wade's Lion, severing the connection between Wade and the Lion, and forms a Mega Spider Robeast. Vince informs the team that he has completed the repairs of the Black Lion which sends Daniel back to the Castle using his "Speed Claws" Voltcom ability to retrieve it. Keith and Larmina board the Black Lion and upon Keith's command, the Lions unite to form Voltron. During the skrimish, they learn that their attacks aren't working and all but the Black Lion are too weak to form the Blazing Sword since it's surrounded by Haggarium-laced webs. But, after a boost from Vince's Voltcom, Voltron goes to full power, forms the Blazing Sword and defeats Kala.

When Pidge shows off the new tail-weapon upgrades, the Voltron Force receives a distress call from Coran who warns them of a moon-base factory on Tarvos that will be manufacturing an invincible army for Sky Marshall Wade. But when they try to rescue him, they fall into a trap set by Wade as the real Coran is trapped inside and must search for him while battling Wade's own experimental versions of the Lions. Meanwhile, the cadets soon learn it's a Coran imposter that's actually a robot strapped with a time bomb and must face it in a fight.

When the cadets grow impatient with their lack of flight hours in the Lions, Daniel convinces the group to borrow the Lions so they can sneak off to go to Planet Doom, Lotor's home planet to grab a sample of Haggarium. But they soon find themselves abducted by Maahox, who studies Vince's strange energy signature. Meanwhile, Lotor invades the Castle of Lions and takes Allura hostage, and Voltron debuts a new reconfiguration ability during the rescue; Lance's red-center form for Voltron with "Magma Pistols".

Hunk takes the cadets on a bonding mission to his secret junkyard called The Hunkyard to learn teamwork and to build "crush cars" so they can have their own vehicles. However, cadet bonding day comes to a halt when an army of Waderoids powered by Haggarium attack them and form together to make a massive scrap monster out of junk. When the rest of the Voltron Force arrives, they take the beast down by taking on a new form that makes Yellow Lion the body and head of Voltron and forms "Rock Wrecking Maces" as his battle weapon.

The Voltron Force travels to the peaceful planet Ariel to defend a race of lion-riding warriors from Sky Marshall Wade who is extracting a powerful metal ore called corite from their mines with Haggarium tipped drills. While playing their video game, the cadets are interrupted by a mysterious ally named Daigo asking for help from an impending danger with the Krelshi, ghostly beasts that are now in a frenzy, and travel with the rest of the team on the mission. Thinking that Voltron force is their enemy, Ariel's ancient lion protectors, the Lion Riders attack, but their leader, Chief Kalon recognizes Princess Allura and tells his riders to back off. They then team up to stop the Drillers, Wade's corite-extracting machines and later the cadets find out what's causing the Krelshi's abnormal behavior and eventually return to normal.

Voltron Force begin noticing several large holes being formed at different locations on the planet. They learn that whatever is creating the holes is apparently a hyperspeed Robeast trying to find the hidden lairs of the Lions. Lance and Daniel take the Red Lion to investigate but they nearly get destroyed when they encounter the assailant. When the rest finally encounters the attacker, the team attempts to form Voltron but before they can complete the formation the Robeast hits them and splits them up. They try several more times and fail each time until Keith calls a retreat. Vince explains that it takes 36 seconds for the formation to be completed and they need to find a way to accelerate the transformation. Daniel and Vince take the Red Lion out to test the theory that Daniel's Voltcom speed can be applied to the Lions and they encounter the creature which appears to be a giant eye. Lance is infuriated that Daniel and Vince again took a Lion out for a joyride, but the other members chide Lance for lecturing the duo instead of thanking them for being able to get a picture of the Robeast. When the beast attacks again the team heads out and finally forms Voltron by having Daniel's Voltcom activate "Flash Form", which skips the familiar commands and forms Voltron immediately. Voltron attacks the giant eye and forms the Blazing Sword to, along with a speed boost from Daniel, finish off the creature, but a shard of it returns to Maahox's own eye and seemingly reveals the Lion's location to him.

Vince's efforts to prove himself to the team end up with him trapped aboard a Haggarium filled shipping vessel that's sinking in a bottomless ocean planet. But he and the Voltron Force debut a new reconfiguration ability while underwater in Allura's new formation of the "Titanic Trident" blue-center form for Voltron.

Keith allows himself to get captured by robots in order to get aboard Wade's invisible prison vessel called "The Void", run by Sky Marshall Wade so he can break out political prisoners of the Den Resistance. However, Daniel gets caught with him and meets Keith's smuggler friend Manset who helps him survive on the inside while Wade throws Keith into the "Black Hole" where he encounters Chief Kalon of the Lion Riders. Daniel then has to fight Kloak, an invisible warrior who guards the Void generator so he and Keith can escape the ship and get their friends to safety.

Voltron Force face their toughest challenge when they take on a powerful newly formed enemy when Lotor's five predators unite to become one powerful robeast. Meanwhile, the cadets test out a new castle defense system for when the team goes away on a mission, but Lotor's ships enter the atmosphere with his five robeasts: a minotaur, a shark, a snake, a wolf, and a dragon.

Princess Allura teaches the cadets about "tact", being ambassadors of Voltron Force, a symbol of peace and justice. But Larmina being bound to Arus is convinced that her home planet is the best at everything and just thinks it's a speech of respecting other cultures. Coran receives a message on the old multi-face diplomatic channel from Sypat, ruler of Planet Ebb. He and his people are no longer willing to stand for Sky Marshall Wade's tyranny of the galaxy and wants to form an alliance with Arus and Voltron Force and asks Allura to come to Ebb. However, Lance thinks it's a trap but Allura takes Coran and Larmina in the blue lion and soon discover Lance was right indeed. They are caught in Wade's blockade of Ebb and are forced to fight in his combat arena that's televised to all the planets during a live transmission. The rest of the force comes to the rescue and Sypat gets Larmina's voltcom back and she helps out as well. Meanwhile, Wade's robots form a giant robot that does battle with a four lion Voltron that's weak without Allura's blue lion, but she manages to form a leg and takes out the giant robot saving Ebb which is now a free planet once again. In the end, Larmina finally learns the value of being a good-will ambassador. Lance and Keith resolve to take Wade down once and for all.

After trying to take Allura out, Voltron Force travels to Earth to finish the fight with Wade once and for all, but are soon hijacked by Wade's Voltron-controlling device. However, Allura refuses to be a part of the team's assault for revenge instead of having Voltron continue to be the Defender of the Universe. Meanwhile, Coran shares his history with Wade when they were cadets at the Galaxy Alliance Academy and how they were selected to pilot the lions. Wade's downward spiral began when he was rejected by the lions because they sensed he wasn't worthy of piloting them. So he set out to prove himself better than Voltron by building his own war machine. Wade's plan comes into effect when he blasts Voltron with a charge of Corite metal dug from the heart of planet Ariel and this rejects the Voltron Force transferring Wade in his place, forming Wade's face as Voltron's head. In order to stop him, Daniel and Vince head back to "The Den" at their old flight academy to get the message out while the rest of the team battle Wade's robotic lions. Vince discovers that Wade tamed the lions with the Corite charge which built its own nervous system that access the nexus and change how Voltron works. Voltron Force and the cadets then combine Voltcom powers to stop Wade and backup arrives when Manset, the smuggler sends an airship filled with Chief Kalon and his Lion Riders to join the battle. Wade is finally taken to jail. Voltron is reunited once again and Allura realizes the Defender of the Universe is ever evolving and is not the same Voltron she grew up with. Meanwhile, Pidge finds out that the Corite charge, when piercing Voltron, pierced Black Lion's piece of the 'nexus', releasing all kinds of seemingly untranslatable ancient data.

After Wade's defeat, Larmina is tasked with organizing a universe victory concert she names The Great Galactic Music Festival for peace. However, she and the others are unaware that Lotor's spies have infiltrated the celebration. Also, the cadets find out Pidge is leading a secret double life when he books Larmina's favorite band Stereolatic and poses as DJ Prong. Meanwhile, the force finds out who the Drule agent is and must battle a giant robeast that was created from the stage using "Tech Ninja Voltron", Pidge's green-center form of Voltron with "Boomerang Shield".

After racing their crush cars, the cadets modify them to transform into their very own version of Voltron they name "Awesometron". But when Hunk gets hungry the cadets take a road trip to Earth for a pizza run, but while there they encounter a dangerous Voltron-obsessed fan named Dudley with sinister intentions. While on Earth, Larmina realization she has missed out on a lot due to her royal upbringing, decides to ditch her teammates and go have some fun with her new friends. Also, Pidge accidentally sets off the Black Lion's security system while trying to remove its piece of the nexus, causing it to come to life, so the force has to hunt the lion down on Arus and bring it back home.

When Pidge can't get into contact with his brother Chip on Intergalactic Ninja Appreciation Day, he gets worried about him and travels with the rest of the force to his home planet of Balto where every inhabitant is a ninja-scientist. While there, they discovery that everyone has fallen off the grid going into stealth mode and turned into mindless "ninja-scientist zombies" with an appetite for Voltron Force brains. They find the root of the cause when Lotor appears and is more powerful than ever when he's able to transform into a Samurai Robeast which Voltron must defeat with Larmina's martial art form with her blazing katana in order to save the citizens from Maahox's brain vacuum for sucking out information about Voltron.

After the Blue Lion is stolen, the remaining lions track it to a barely inhabitable frozen planet. When they locate the stolen lion, Voltron Force finds out the long-lost former Blue Lion pilot, Sven has returned and had stolen the Blue Lion in an effort to save his son. But Sven is then double-crossed by Maahox and the force must help their old teammate in order to get his son back.

Maahox develops a gremlin-like holographic pet, which he sends to attack the Castle of Lions through Pidge's videogame. When Vince finishes the game, beating the final boss, he downloads his prize—Maahox's pet and names him "Gary". However, the seemingly harmless cute creature soon causes chaos for the force by multiplying himself in order to destroy the castle's defenses. After being captured by Hunk's space mouse trap device, Gary escapes and grows into a monstrous version of himself as he attacks the Voltron Nexus. Pidge finds a way to defeat Gary by re-rigging the mouse trap to make what he calls a "Gary Bomb" so the space mice can carry it inside the creature, but in the end, the damage to Voltron's inner workings has caused major damage.

After trying to repair the Black Lion's Haggarium-infected Nexus, the Voltron Force track the lions to planet Ariel. However, they must survive a series of trials in the Path of Lions, Den of Creation, sacred grounds deep inside the mines in The Forge where Voltron was originally forged in order to find his creator. But the Krelshi (electric spirit lions) blocks Vince from the entrance warning him that even though he's worthy of being on the force, he's not ready for the trials yet. Meanwhile, the trials are taking place down below; first the team must escape a giant electrified circuit board tech puzzle. Then the team must speed through a series of death-traps of swinging blades and giant hammers. Next are two chambers that contain lazer towers aimed at them and battle robots they have to fist-fight with. Lastly, they come to the Blacksmith workshop where Voltron was created by the union of five planets; four of which they know to be Balto, Ariel, Earth, and Arus. This room leads to a battle with the Krelshi, leading Vince to unify the team by getting past the trial himself and joining them in the fight.

Needing a vacation, the Voltron Force heads to Manset's new luxury resort, "The Leisuredrome" on the rest and relaxation planet of Dradin. But while there, ex-military soldiers from Lotor's army poised to take Dradin by force. Meanwhile, Vince wants to premiere his documentary about Voltron there. However, he and the rest of the cadets cannot go to Dradin since the invitation is for pilots only. This doesn't stop the cadets though and they decide to form "Awesometron" and sneak away to the planet.

While awaiting Wade's conviction at his trial, Vince constructs a prototype for a mind-link interface, a way for the pilots to be better connected to Voltron's control system. However, when Daniel tries it on for size, his consciousness is accidentally transferred into Voltron and suddenly, he finds himself in Voltron's robotic body. But Wade manages to break out of his restraints and escapes the courtroom, leading Daniel to go after Wade who merges with the same cocooning Robeast that previously attacked Arus before. Now, the Voltron Force must save Daniel and return his mind to his body before it's too late.

The Voltron Force receives a distress call from an abandoned Arusian ship from centuries past that leads them to a haunted spaceship graveyard where a swarm of bat-like Robeasts and Lotor's command Drule ship await. Meanwhile, when Keith and Allura get separated from the rest of the Force, it's up to Daniel to form Voltron and save the day with the rest of the team. Also, while onboard the ghost ship, Keith learns that his ancestors are not from Earth, but from Arus, like Princess Allura, and the ship was under the command of his great-grandfather, who was a Knight of Arus.

When Maahox creates a seed filled with Haggarium, Allura comes face-to-face with the now grown treacherous tree that's taken over a farm and has to make an important decision about her future. She must choose between becoming Queen of Arus and helping her people or remain the Blue Lion pilot as a member of Voltron Force. Meanwhile, the cadets, minus Vince, battle the poisonous tree on foot, but soon Larmina finds out that Daniel is infected from the Haggarium and they keep it a secret from the team. Allura decides she needs to serve as Queen of Arus, and turns over piloting the Blue Lion officially to Larmina.

Maahox replicates King Lotor into a powerful army of clones who attempt to take over Planet Arus and destroy Voltron once and for all. Meanwhile, Coran has to keep the soon-to-be crowned queen, Allura busy so she won't discover her coronation surprise party. Lotor then learns Daniel has Haggarium in his body while Vince and Daniel discover they're now able to share their own powers with each other. This is discovered when the Voltron Force finds themselves battling a returning Predator Robeast, and the Boomerang Shield is not enough. Also, realizing that he serves better in the castle's defenses, Pidge hands over the Green Lion piloting duties to Vince, leaving Keith, Lance and Hunk wondering who Daniel will eventually take over for in the future.

Voltron Force takes on a fully powered King Lotor, all while fighting a rogue spider Robeast that is able to merge itself with its foe.

It's the final battle for the Voltron Force as Castle Doom is transformed into the largest Robeast ever, attempting to destroy the Galaxy Alliance and create galactic chaos!

An expedition on the moon Kerberos is attacked and the crew imprisoned by a hostile alien craft from the Galra Empire. On Earth, they are presumed dead. One year later on Earth, Garrison cadets Lance, Pidge and Hunk witness a vessel crash land and learn that it contains one of the missing expedition members, Shiro, who has been quarantined by officials. As they form a rescue plan, an academy washout known as Keith arrives and rescues Shiro before the five of them escape into the desert. Shiro is unable to remember anything from his captivity, but the group are able to determine that the Galra are searching for a weapon known as "Voltron". They find a large robotic blue lion in the desert and learn that it is only one of five lions that form Voltron.

The Blue Lion accepts Lance as its pilot and takes the five through a wormhole to the Castle of Lions on Arus, where they find Princess Allura, her royal advisor Coran and four space mice in cryostasis. Upon awakening, Allura is shocked to discover that 10,000 years have passed since they were placed in cryostasis. Haggar, advisor of Zarkon, leader of the Galra Empire, senses Allura's return and Zarkon sends Galra troops commanded by Sendak after them. Allura names the others as Voltron Paladins, bestows them with armor and bayards (the Paladins' weapons) and tasks them with finding the other lions. Lance and Hunk retrieve the Yellow Lion while Shiro accompanies Pidge to find the Green Lion. The Red Lion, unfortunately, is in the hands of the very Galra ship advancing on Arus. Unsure of whether to run or fight, Allura consults the artificial intelligence formed by the memories of her father, King Alfor, who admits he was wrong to hide Voltron and encourages her to fight.

Keith, Shiro and Pidge infiltrate the ship so Keith can find the Red Lion while Shiro and Pidge, who repurposes a Galra drone dubbed "Rover", search the ship for prisoners, revealing to them that Pidge's father and brother were the other missing astronauts from the Kerberos mission Shiro was on. With the other four lions retrieved, the Black Lion is released from the Castle and selects Shiro as its Paladin. All five lions unite to form Voltron and destroy Sendak's ship before accepting their new roles as the Defenders of the Universe.

When the Paladins are unable to form Voltron during a training session, Coran puts them through his own rigorous training in order to build a sense of brotherhood and trust between the Paladins. However, the Paladins fail miserably and are unable to connect. It is not until the Paladins engage in a food fight with Allura and Coran that they finally begin to work as a team and are successfully able to form Voltron.

As the Castle of Lions prepare for departure, the team is met by the arrival of a local Arusian. Allura heads to meet the villagers along with Coran, Hunk, Keith and Lance while Pidge and Shiro tend to the rescued prisoners from the Galra battleship. From them, they learn that Shiro was a champion fighter in the gladiator ring that he and Pidge's brother, Matt were forced to fight in and that Shiro seemingly attacked Matt in bloodlust. Pidge and Shiro head to the crashed Galra battleship they had destroyed to retrieve prisoner logs, but are interrupted by the arrival of a Robeast created by Haggar to defeat Voltron. During the fight, Shiro remembers the Robeast as the Galra warrior he defeated in battle and is able to use his previous tactics to defeat it. Keith uses his bayard to form Voltron's sword, allowing Voltron to deliver the finishing blow. Afterwards, Shiro reveals to Pidge that he remembered attacking Matt so that he wouldn't be forced to fight and instead be sent to a work camp with his father. Pidge apologizes to Shiro and it is revealed Pidge's real name is Katie. With the defeat of the Robeast, Sendak is tasked with acquiring Voltron.

The team and Arusians celebrate Voltron's victory in the castle, but the festivities come to a halt when Pidge reveals her intentions to leave the team and search for her missing father and brother. As the team tries to convince Pidge to stay, Haxus, one of Sendak's soldiers, is able to sneak a bomb drone disguised as Rover into the castle, causing it to destroy the crystal that powers the entire castle and severely injure Lance in the process. Coran and Hunk leave to acquire a new crystal, Keith and Allura rush to the Arusian village as it is being attacked by the Galra while Shiro and Pidge remain at the castle with Lance. The attack on the Arusian village was however a distraction and Sendak attacks and overpowers Shiro and takes over the castle. Pidge evades capture and with Allura's guidance is able to sabotage the Galra's efforts to launch the Castle. Meanwhile, Hunk and Coran arrive at a nearby Balmera, a large petrified creature the size of a planet from which the Alteans acquire crystals. They discover that it has been taken over by the Galra and crash in the subterranean mines.

Hunk and Coran meet local Balmerans, Shay and Rax, who help them hide from the Galra. Shay admires the two and wants to help them, but Rax is cautious and insists they leave. Hunk and Coran are able to sneak past the Galra to find a crystal, but are captured and imprisoned. Shay helps them escape with the crystal, but is captured by the Galra after her brother informs them of Shay's actions. Hunk promises to return and save her people before he and Coran return to Arus. Still trapped outside the castle, Keith and Allura are unable to help Pidge take back the Castle. With Allura's guidance, Pidge is able to continually sabotage the Castle's systems to further delay Sendak's take off. She sends Haxus falling to his death, taking Rover with him. In flashback, Katie Holt watches the news in horror as she learns of her father and brother's apparent demise on the mission to Kerberos. Katie breaks into the Galaxy Garrison and accesses Commander Iverson's files of the mission. When she is caught by Iverson, she presses him about the crash despite probes showing no evidence one but Iverson reprimands her and bans her from ever entering the Garrison again. Some time later, Katie enrolls in the Garrison, but cuts her hair and wears glasses, passing herself off as a male student named Pidge Gunderson. The space mice are able to take down the particle barrier, allowing Allura and Keith to enter the Castle and help Pidge against Sendak. With Lance in recovery and Sendak imprisoned, Pidge decides to remain on the team.

The team welcomes Lance back after a period in the healing pod before deciding on their next move. Hunk brings up the plight of Shay and her people; prompting them to launch a liberation mission. Pidge also finally gets a weight off her shoulders by revealing her gender to the rest of the group. On the way to the Balmera, the team stops to help two rebels, Rolo and Nyma, on the run from the Galra. While the others are open and trusting to the pair, Hunk is cautious and guarded and eager to get to Balmera as soon as possible. Lance flirts with Nyma, who convinces him to take her for a ride in the Blue Lion, but once they are alone, Nyma ties Lance to a tree while she and Rolo take off with the Lion. The other Paladins pursue them into an asteroid field and Keith is able to flush them out and they reclaim the Blue Lion. Rolo and Nyma are left stranded once more, but Rolo expresses gratitude for the Paladins sparing their lives and genuinely hopes that they can defeat Zarkon.

Allura, Coran and the Paladins return to the Balmera to free the natives, but must hold back their firepower so as not to hurt the Balmera. Shiro and Pidge scout for Galran forces, who are strangely absent, while Lance and Keith work to disable a Galran fleet of ships. Hunk searches for the prisons and is able to find Shay's family, including her brother Rax, but learns that she was taken by the Galra to the heart of the Balmera after they arrived. The Paladins make their way to the Balmera's core to rescue her, but fall into a trap. Shay uses the Balmera to transmit a message to her family, who are able to free them with the Balmera's help. The Paladins form Voltron and are able destroy the Galran fleet, but their victory is short-lived by the arrival of another Robeast.

The Paladins scramble to battle the new Robeast, whose omni-directional view and multi-firing ability make it difficult for Voltron to counter, forcing them to retreat to the tunnels below and regroup. They learn that the Balmera is dying and unless they leave, everything on the Balmera will die as well. Though the Balmerans are reluctant to leave their home, Allura convinces them to flee to safety. The Paladins distract the Robeast while the Balmerans climb to the surface to escape on the Castle-ship. However, the Balmera's waning life force causes structural damage to the tunnels, leaving many of the Balmerans trapped. Unable to fully evacuate, Allura decides to perform an ancient ritual once performed by her people to rejuvenate the Balmeran. Hunk's bayard forms a large shoulder cannon for Voltron, granting the Paladins equal fire power against the Robeast, but they are still unable to defeat it. With help from the Balmerans, Allura's ritual is able to revive the Balmera, which defeats the Robeast by encasing it in crystal, but she passes out from exhausting her energy.

As Allura recovers, she spends her time enjoying the company of her father's artificial intelligence. With Sendak in custody, they decide to draw out his memories in order to learn information about Zarkon and the Galra empire. While waiting, the Castle begins displaying strange behavior: Hunk and Pidge are attacked by malfunctioning kitchen equipment and later stuck in zero-G, Lance is locked in a cryo chamber and later almost sucked out of an air lock while Keith is attacked by a rogue training droid. Keith opens a door in the airlock and the rogue training droid is sucked out, and he saves Lance before closing the airlock. Shiro monitors Sendak and begins interrogating him, but is mentally tormented by Sendak's voice prompting him to eject Sendak into space. Coran concludes that Alfor's AI has been corrupted by the lingering effects of the Galran crystal as they try to stop Allura, convinced that Alfor is taking her back to Altea, from driving the Castle-ship into an imploding star, which the AI makes her see as Altea. To make matters worse, it erects a force field around Allura, so she is unable to hear anyone else. Coran presses his hands against the force field and is able to bring Allura back to her senses. At the urging of the Alfor AI, Allura tearfully destroys her father's memories in order to save the ship. Despite the loss, Allura stands strong and maintains that Voltron is her father's legacy.

While combing through Sendak's memories, the team discovers the location of a secret Galran transport hub. Allura joins the Paladins in infiltrating the station in order to extract information, but find nothing useful. When another ship arrives, Allura decides to infiltrate the ship herself to extract its information by making use of her Altean ability to change her skin color and height, allowing her to resemble a Galran soldier. Shiro accompanies her, unwilling to let her go alone as well as needing his hand to access Galran technology. While waiting, the Paladins spot one of the Druids with two large containers of yellow fluid. Keith pursues them and Coran discovers that the Galrans have found a new way to harvest Quintessence, a form of fuel that has also allowed Zarkon to live 10,000 years. Keith is discovered and battles the druid, but is injured by the druid's lightning only to be healed by the yellow fluid before escaping in Pidge's Green Lion. Shiro and Allura are also discovered and flee to the escape pods, but Allura sacrifices herself to allow Shiro to escape and she is captured by the Galra.

This episode follows the end of the previous episode, where Allura is captured and Shiro blames himself for her imprisonment. He vows to follow her into the heart of the Galra Empire to save her.

In this episode, Shiro and the remaining Paladins save Allura, but the wormhole is damaged as they are attempting to leave the Galra fort and are lost within it, unknown as to where they are.

The lions fall out of the wormhole in different places, while Coran and Allura are trapped in a seemingly endless time loop that makes Coran younger and the mice into different creatures. Meanwhile, Zarkon seeks to uncover the person responsible for the Paladins' escape. Pidge exits the corrupted wormhole in a junk nebula with debris from various alien technologies, which she uses to send a homing beacon to the Castle, thus breaking the time loop. Keith and Shiro crash on a nearly dead moon. With Shiro growing weaker from the wound Haggar inflicted on him in the previous episode, they work together to survive the local wildlife until their lions are back on-line.

Hunk and Lance crash-land underwater and follow a mermaid to a civilization whose queen promises to keep them safe and help find the others. While resting, Lance is kidnapped by a trio of mer-people who believe the queen to be mind-controlling the populace. Only after freeing Hunk of the control and capturing the queen do they realize that the queen was also mind-controlled and the Baku, which was a food source to the people, was really an alien predator beast. Lance channels a new weapon from his Blue Lion and kills the Baku, and as a thank-you the queen uses the old energy beacon, which brings Pidge to their rescue.

Following the team's reformation after the corrupted wormhole jump, Shiro is in a recovery pod and vividly dreams of the day he escaped. A Galra scientist named Ulaz released Shiro, and instructed him to get back to Earth and find Voltron. Shiro also relates that not all Galra are evil, as a Galra was the previous Black Paladin of Voltron. Finding space coordinates in Shiro's artificial arm, the Paladins locate Ulaz, who reveals he is part of an order known as the Blade of Marmora, who are hidden within many ranks of Zarkon's Empire. Prorok, who is remade into a Ro-Beast, finds the Paladins and quickly gains the upper hand, until Ulaz sacrifices himself to destroy the monster. Before his death, Ulaz gives the team the location of the Blade of Marmora's headquarters; Shiro and the group decide to wait on journeying there until they learn how Zarkon is tracking them. In his room, Keith holds a small dagger he has had since childhood, which bears the crest of Marmora.

While making repairs to the Castle, the Paladins encounter unusual spongy spores that lead them to a planet of brilliant engineers — the Olkari. When landing, Team Voltron meet the Olkari people in the forest, where they adapted from machine- to nature-based technologies. When rescuing the Olkarian king Lubos, Team Voltron find he willingly sold out his people as slaves to live in comfort, while his people build a super-weapon for Zarkon's forces. Voltron engages the super-weapon cube, which learns and adapts to their attacks, even replicating them. When Voltron attempts to slice the cube, it splits into four. After Pidge has help from the Olkari, she reconnects to her Green Lion in a way that allows her to summon a new weapon, which when the Black Cubes attempt to clone, instead causes them to grow massive plant roots and fall to the ground. When leaving Olkarian space, the Castle of Lions is intercepted by a Galra war fleet.

Exhausted after a battle, the crew must spring back into action when Zarkon's forces track them down. Though they manage to escape, their wormhole generator begins malfunctioning while in slipstream because of broken teludav lenses. Coran gets a case of the Slipperies, an Altean flu which causes profuse sweating all over. When Team Voltron attempt some rest — Lance and Keith try to make it to a pool, Hunk makes transparent blue cookies, Pidge learns beginner Altaean, and Shiro is on watch — Zarkon's ship discovers them again, and another battle and jump leaves them without any more crystal lenses needed for another wormhole. When the Castle hides in a cosmic storm cloud, Allura comes to the conclusion that Zarkon is following them by tracking her energies. In engineering, Coran details what type of lens material they need, and Pidge remembers that Hunk's cookies are that very substance. Coran positions the paladins holding the cookie-lenses in a unique fashion INSIDE the wormhole generator in order for it to properly function. Using his Slipperies, Coran shines the lenses, which fully jumps the Castle away from Zarkon.

On the ravaged planet of Taujeer, Galra commander Morvok strips the planet of resources and prevents the citizens' escape. Allura and Keith, who also believes himself to be the means of Zarkon's tracking, go off on a separate mission to learn how Zarkon is actually locating them; and on their isolated trip debate whether any Galra people are even fighting Zarkon's rule. The remaining four Paladins arrive on Taujeer to help the Ark escape, only to be fired upon by Galra forces closest to them, as Zarkon located them nonetheless. When Keith and Allura are summoned by Coran, Keith tries to use the booster jets to arrive sooner, but ends up destroying the pod instead. Hunk activates a new power-up for his Yellow Lion, which prevents the Ark from falling into a lake of acid. The Red Lion ventures into space to Keith and Allura's position and retrieves them to form Voltron, which defeats the Galra ship. After saving the Ark and resting in the Castle, it is apparent to them now that Zarkon is following them by way of his old connection to the Black Lion.

Shiro attempts to create a deeper bond with the Black Lion, while Coran takes the others to a swap meet, where they have some strange adventures. After Coran details his time in the swap meets as edgy and filled with space pirates, they arrive and find it to resemble an average mall on Earth. Varkon, a bumbling mall rent-a-cop, sees the four Paladins drop their terrible disguises and pursues them through the mall. Keith goes to a knife salesman for information on the blade he has, but learns it is from an extinct people. Hunk is made to work off a tab for Sal, the owner of Vrepit Sal's diner, but has to eventually run from Varkon. Pidge and Lance find a shop which sells Earth material from the 1980s. They all eventually meet up with Coran, who has the lenses. Meanwhile, the Black Lion reveals how it was created, and how Zarkon and Alfor were once friends. Zarkon then connects to Shiro on the psychic plane, but Shiro's words of trusting his Lion earn its protection and defeat of Zarkon in the psychic plane. Waking up, Zarkon loses more connection to the Black Lion and Shiro is now more connected to it. Afterwards, knowing Zarkon can no longer track them, Shiro orders the Castle to the headquarters of the Blade of Marmora.

When Team Voltron reaches the headquarters of the Blade of Marmora, they find it located in a safe spot between two black holes and a blue Supergiant star. Keith and Shiro travel to the Marmorans' base in an effort to align with the Blade of Marmora, led by Kolivan and his lieutenant, Antok. But Keith's possession of one of their blades causes immediate friction, with the Trials of Marmora to resolve them with one of two results: knowledge or death. Keith must fight to unlock his past, and with each fight exhausts himself more and more. When entering a vision of his old home with his father, the outside of the house shows a Galra invasion, giving Keith a choice: stay and learn, or leave and rescue. The Red Lion attacks the base, sensing Keith's endangerment; and, deciding to end the Marmorans' mistrust and gain their alliance, Keith relents his dagger, only for it to awaken its true form of a saber upon his enlightened decision and reveal a truth: Keith has part Galra ancestry. Meanwhile, Commander Thace (the Marmoran spy who shut down the Solar Shield) alerts the Order that the investigation is increasing and the timetable must escalate to now.

The Paladins split up to gather resources for a showdown with Zarkon. Hunk and Keith -the latter dealing with the fact that Allura now views him with contempt since learning he was part Galran- travel into the belly of the planet-devouring creature known as a Weblum for scaultrite, a material needed in wormhole generators. While there, they see that the instructions Coran made are dated to when he was in university and are corroded. The duo successfully enter the Weblum, but are separated after the first stomach, leaving Keith in the second and Hunk in the Weblum's bloodstream. In the second stomach, Keith finds a trapped, silent Galra pilot who helps him journey through the third stomach to reach the scaultrite. As the Weblum's defenses flare, the only way to make the scaultrite is for Hunk to threaten the beast enough outside to form the crystals. Upon the Weblum firing its beam, Keith packs more than enough scaultrite, but the Galran with him holds him up for a single full bag, and escapes. Keith thanks Hunk for his efforts, and Hunk pokes fun at Keith's newly learned Galra ancestry.

By the information provided by the Blade of Marmora, Lance, Pidge and Shiro infiltrate a facility to free the only prisoner of the Galra Space Station Beta Traz. Upon successful infiltration, Pidge locates two cells instead of the one they were informed of. Pidge stays in the Main Command Center, but Lance and Shiro must reach and connect to the isolated Third level holding the two prisoners. Lance obtains a 3D render of a Galra officer for the facial recognition. They each think they've found the right inmate, but it gets harder to tell as Pidge goes radio silent when the station warden goes to the Command Center. Lance escorts his choice out, while Shiro deals with his inmate, Slav, being impossible because of his predicting statistical probabilities of his death from the smallest thing. While Pidge is disabling the remaining security features, she finds footage of her brother Matt's escape. When the gravity is shut off, Shiro with Slav regroups with Lance, who learns he actually has the warden's personal pet Laika. In the hangar, everyone is regrouped but the Warden overpowers them until Slav opens the hangar doors to save the Paladins. Lance uses his aim to save Slav from the Warden and the mission is a success.

Allura travels to the Balmera to acquire a powerful crystal. When she is about to leave with the crystal, the panoptic Ro-Beast from their last encounter prompts her to call on the Paladins for help. The creature, now merged with part of the encasing crystal it was once in, makes its way to the Castle as Allura goes skyward to protect the Balmera. Allura warps in the Paladins, who regroup to their Lions to form Voltron. As they fight the Ro-beast, the team utilize their new weapons to subdue it, and Voltron finally destroys the monster. Back on board the Castle, it is more apparent that the fact that Hunk and Keith were successful in their part of the mission doesn't change anything in Allura's distrust of the latter. On the Olkarian home world, the super teludav is operational, and the team reminisce about their time since coming together. Meanwhile, Thace makes the error of returning for a spy device he planted, only for the Druids to intercept and capture him.

After acquiring the teludav from Olkari, the team prepares to launch the operation to defeat Zarkon and bring peace to the universe. When the Marmorans haven't heard from Thace, they urge a delay in action, while Allura argues they continue. Keith plans to infiltrate the main ship of the Galran Fleet, but before he leaves, Allura stops him to apologize for ever doubting him, explaining that since waking up she views the Paladins as her new family, and her blind hatred of the Galra combined with Keith being part Galran made her unsure. Following Thace's capture, the Druids interrogate him, and allow him to escape. Haggar helps Zarkon find the Black Lion, Zarkon's fleet arrives, and Shiro distracts them while Keith sneaks aboard. Despite the battle being a trap, Zarkon is too engrossed in reclaiming the Black Lion. Since the Druids rewrote the shield codes, the plan adapts to turn the core room into a bomb and cripple Zarkon's ship. While the Druids are sent after Thace, Zarkon has a rematch with Team Voltron. Thace sacrifices himself to cause the power core to overload and explode, just as the super teludav loses its cloak, and Zarkon's ship loses power. As Zarkon's ship is wormholed to another reach of the universe far away, the Paladins pursue to finally defeat Zarkon.

The Paladins fight to systematically destroy the base to prevent Zarkon's return. As Zarkon himself goes to battle Voltron, Haggar and her Druids go to protect their emperor as he readies his armor, which untested could kill him as well as Voltron. Before Zarkon can do anything, Haggar uses her dark magic to forcefully remove the Quintessence from Voltron, but is overloaded by the purity of Voltron. While the Lions are unresponsive, their Paladins still live, but Zarkon arrives in a Ro-beast in his image. Allura uses whatever power she can to stall Zarkon to allow the Paladins to recover and battle Zarkon's Ro-beast, nearly resulting in her own demise when Zarkon deflects her attack back at the Castle, critically damaging and disabling it. Somehow surviving, Allura, Kolivan and Antok go to battle Haggar to keep her from using her witchcraft from delaying Voltron. As their battles rage, Zarkon splits Voltron back into the individual Lions; Allura and Kolivan triumph in their fights, while Antok perishes at the hand of Haggar and another Druid. Shiro awakens to see his team being beaten, and the Bayard access port in his Black Lion activates, in turn activating its Transcendent Wings to phase through Zarkon's Ro-Beast and reclaim the original Black Bayard. As their fight continues, Haggar is revealed to be Altaean; Allura learns that she herself has the power to command Quintessence, which she uses to defeat Haggar and destroy the Komar, the base's Quintessence harvester/weapon; and Kolivan avenges Antok. Forming Voltron, the Paladins fight with new strength, and Shiro uses his Bayard to supercharge the Voltron Sword and destroy Zarkon's Ro-Beast armor. After the battle, the Paladins discover that Shiro has vanished from the Black Lion, leaving the bayard behind. On Zarkon's ship, Zarkon is on life support, prompting Haggar to summon Prince Lotor.

The Paladins must adjust to using only their lions until they can figure out a new means to form Voltron. As they free the people of Puiga, Zarkon's son Lotor takes over the empire in his place, and covertly begins a nefarious plan.

Team Voltron shuffle who now pilots which Lions: Keith takes the Black Lion, Lance takes over for Keith's Red Lion, and Allura is chosen by the Blue Lion. Lotor traps the Paladins over Puiga to study their team dynamic after Zarkon's defeat, and pulls out of battle after learning what he wants to know.

Keith, in burning pursuit of Lotor, is easily tricked into following the prince to a storm planet where their sensors malfunction. Keith's blind pursuit causes everyone to separate, but Allura syncs with the Blue Lion and outmaneuvers Lotor to escape and form Voltron. Keith, now focused on his new responsibilities as leader, allows Lotor to escape so as to regroup.

The team comes across an Altean vessel lodged in a spacial anomaly and pass through it to study. Upon crossing, they find themselves in an alternate universe where the Alteans defeated the Galra 10,000 years ago and have conquered the known universe to "bring peace". They learn that a comet with multi-dimensional properties is made of the same material that makes up Voltron, and if the Alteans get it, they'll be able to conquer other realities. The team, alongside the Guns of Gamora, including Slav and Sven (Shiro's counterpart), work to steal the comet and return to their reality. Upon returning, Lotor takes the comet with ease from the tired Paladins.

Shiro wakes up with longer hair & facial hair in a Galra cruiser and escapes. Unbeknownst to him, the commander speaks of an "Operation: KURON" where they let him escape. Shiro then lands on an ice planet and meets two rebels who give him a shuttle. Shiro uses the shuttle to stealthily re-board the cruiser and makes his way to Voltron. After a week of open travel in space, Keith finds Shiro and takes him home.

Lotor's four Generals attack a Galra base to steal a Teludav lens (from episode "Blackout") and the team barely survive a battle with Lotor's forces, where Keith realizes one of the generals is the Galra that was trapped in the Weblum. When Keith is confronted with the difficult choice of pursuing Lotor or destroying the Teludav, he tricks Lotor's generals into a shoot and miss, destroying the Teludav and leaving Lotor open to attack. However, the generals manage to escape.

At the Castle, Coran explains to everyone the true origin of Voltron and the Paladins: King Alfor and Zarkon, despite differences between their peoples, worked united in the defense of their kingdoms. When celebrating a battle victory on Zarkon's homeworld of Daibazaal, a comet lands not far from them made from multi-dimensional properties, which Alfor used to build Voltron. When evil erupted, Alfor & Zarkon came to pilot the Red and Black Lions respectively; with their friends Lady Trigel of the Dalterion Belt, Blaytz of Nalquod and Gyrgan of Rygnirath piloting the Green, Blue and Yellow Lions respectively. Zarkon's wife, Altean alchemist Honerva, had been poisoned by the close studies of Quintessence while studying the space rift which the comet came through. Zarkon then tricks the original Paladins into taking him and his wife into White Space (a reality of pure Quintessence) to restore his beloved wife, but it ended up killing them both. To close the portal for the protection of everyone, Alfor and the other paladins destroyed the Galran homeworld, Daibazaal. Afterwards, both Zarkon and Honerva were resurrected by Dark Quintessence from the other universe into the Emperor Zarkon and Witch Haggar they are today, but Haggar had also lost her memory. The Galra immediately responded to their leader and attacked many planets. King Alfor was killed by the corrupted Zarkon after scattering the Lions across the universe, and Zarkon destroyed Altea.

Afterwards, the team pieces together Lotor's plan based on recent events: to gather the purest Quintessence possible from different universes. Haggar remembers what her husband did to revive her and restores Zarkon to consciousness.

Keith continues his training with the Blade of Marmora by accompanying them on intelligence missions, in the process neglecting his duties as the leader of Voltron. When Kolivan reveals that the Galra most likely have a secret supply chain of a new form of Quintessence, Keith joins the mission to infiltrate one of the Galra supply vessels. The Blade discovers that the vessel is a trap once they are aboard, and the Marmoran Regris is killed in a subsequent explosion. Despite this and Allura's plea for Keith to continue to lead Voltron, Keith continues to spend most of his time with the Blade of Marmora. Some time later, the Paladins receive a distress signal from a rebel convoy under attack by the Galra. The four Paladins struggle to hold off the Galra while Keith is absent. Shiro pleads the Black Lion to let him pilot it, successfully reestablishing their bond. Shiro reconvenes with the other four lions and together they form Voltron, which easily destroys the Galra fleet. After the battle, Keith confronts the team and officially steps down as the leader of Voltron, handing the position to Shiro so that he can continue to work with the Blade of Marmora.

Pidge has a flashback of Matt coming to comfort her after a rough day at school. On Olkarion, Pidge leaves the team to pursue a lead on Matt. She meets with an arms dealer to negotiate the information, but has to force it from him when he tries to capture her for the bounty he'd get. A hooded figure asks where the "boy" went, and the arms dealer reluctantly admits he thinks it was a Paladin of Voltron who attacked him. Pidge follows the information from the arms dealer to a rebel base, aiding in fighting off a Galra attack. She finds her lead, Te'Osh, is mortally wounded. Te'Osh gives her Matt's transponder code, which leads her to a space graveyard for rebel fighters. Devastated, Pidge finds a grave marker with Matt's name on it, but the date of birth is wrong. She figures out it's a quantum frequency that conceals a set of coordinates, leading her to a spy lair on a seemingly remote asteroid. A masked figure attacks her and Pidge fights him briefly, only to realize it is Matt. Their reunion is cut short when the bounty hunter from earlier interrupts. The siblings team up to take the bounty hunter out.

Emperor Zarkon has fully revived and reclaims the Galra throne. Zarkon relieves Prince Lotor of duty while Haggar, still suspicious of Lotor, keeps an eye on him. Meanwhile, Matt meets the Paladins and Coran and finishes Pidge's Galra tracking system with intelligence he collected while working with the rebels. While spying on Lotor, Haggar learns that he has obtained the trans-reality comet and has made two ships from its ore, and is planning to make another. She informs Zarkon, who orders her to hunt down Lotor. However, Lotor kills Narti, one of his generals, after realizing Haggar is spying on him through her. Matt, Pidge, and Hunk discover a way to decrypt Galra communications and discover that the Galra are attacking a seemingly empty area of space. The Paladins set out to defend whoever the Galra are attacking, accompanied by Matt, who operates Voltron's cloaking capabilities in Pidge's lion. When they arrive at the point of interest, they learn that Zarkon is attacking Lotor, and are forced to defend against the Galra fleet once Voltron's cloaking technology fails. Lotor and the Paladins manage to escape the scene as Zarkon broadcasts to the Galra Empire that Lotor and his henchmen are to be killed on sight by any means possible.

Shiro tasks Coran with organizing promotional Voltron appearances to bolster public support for Voltron and the rebel cause. After organizing a terrible show to hospital patients, Coran quietly buys an illegal mental enhancement pill from one of the patients. The team expresses doubts in Coran's ability to manage Voltron appearances after he botches a visit to a planet whose occupants can safely go outside for only one day per year. That night, Coran places the pill he bought under his pillow, which hatches a worm that latches onto his brain while he sleeps. A more energized Coran organizes many successful shows, to the increasing chagrin of the Paladins. To enhance the spectacle during their last show, Coran summons a monster from the planet they visited earlier to battle the Paladins. After an alien removes the worm from Coran's brain, Coran warns the Paladins of the monster's danger. To the thrill of the audience, they ward it off. Coran later apologizes to the Paladins, but Shiro admits that Coran's shows were very effective.

With the coalition against Zarkon sufficiently large, the Blade of Marmora and Shiro construct a plan to reclaim one third of the Galra Empire by taking down the Galra-occupied planet Naxzela. Prince Lotor leads his generals to the remains of Daizabaal, where he has secretly erected a gate around the inter-reality rift where his mother had worked. Lotor uses the last of his Quintessence to enter the field between the realities to collect the infinite supply of Quintessence therein. The coalition begins its plan to reclaim part of the empire. Pidge and Hunk disable a communication satellite while the Blade of Marmora and a team led by Matt hijack large cannons that they use against the Galra. Once Acxa, Ezor, and Zethrid realize that Lotor's gate does not work, Acxa stuns him with the intent to return him to Zarkon in exchange for a pardon. However, Lotor manages to escape his handcuffs once he wakes, and flies away in his cruiser. The satellite that Pidge and Hunk have disabled begins to work again, and Haggar learns of the Empire's defeat.

The coalition's success is abruptly interrupted when an incoming Galra cruiser remotely disables the Galra technology they were using. Lotor is spotted by the Empire in deep space and is pursued by Zarkon's fleet, only narrowly escaping. Haggar, focused on stopping the coalition's tirade, begins a ritual that traps Voltron on Naxzela's surface by multiplying the intensity of the planet's gravity. Unable to move Voltron, the Paladins flee to the planet's core to find and disable the source of energy causing the gravity change. There, Allura attempts to disarm the planet's energized core, to no success. Hunk observes that the planet's soil is highly volatile, leading the Paladins to realize that the planet is being used as a bomb that will detonate when a Galra cannon fires at it. Unable to communicate, Keith and Matt confront the oncoming Galra cruiser. While listening to Galra communications, Lotor learns about the impending explosion and heads towards it. As the Paladins try to escape Naxzela, Lance encourages Allura to use her Altean abilities to overcome the planet's gravity, which she manages to do. After Voltron, the Blade, and Matt's team regroup, they realize that they cannot disarm the cannon on the Galra cruiser without taking down its force field. After their attempts to shoot at it fail, Keith nearly sacrifices himself to ram into the shield before a powerful blast from Lotor's cruiser destroys it. Lotor asks the coalition to "have a discussion" despite their differences in the past.

The Paladins, following a lead from Lotor, successfully infiltrate and destroy a sentry construction facility. Still unsure of his allegiance, they're reluctant to let him out of captivity, so Lotor offers a more personal bargaining chip; the last-known whereabouts of Commander Sam Holt, Pidge and Matt's father. Matt and Pidge rush in to the prison their father was held in, accompanied by Rolo, Nyma, and Beezer, but Pidge is forced to drop the others off while she draws away the Galra fleet. While Rolo and Nyma set about freeing the prisoners, Matt looks for his father, only to find he has already been moved. They return to the Castle of Lions, where they receive an incoming transmission from Zarkon. He demands an exchange of prisoners: Commander Holt for Lotor.

Upon receiving the transmission, Pidge immediately agrees to the trade and becomes enraged when the others are reluctant to agree. Lotor counters with a warning that Zarkon will likely double-cross them. Nevertheless, the Paladins agree to the exchange, and Pidge, Matt, and Shiro head to the rendezvous point in a shuttle while the others wait out of range in the Castle. Elsewhere, Haggar retrieves a fraction of her lost memories, realizing that Lotor is in fact her son. The prisoner exchange seems to go well, until Pidge runs out to greet her father and realizes it is a hologram. Zarkon then demands Voltron in exchange for Commander Holt. Immediately, Lotor attacks Zarkon, and Pidge, Matt, and Shiro pursue Lotor's former generals as they make off with Commander Holt. The other Paladins and Coran move in to assist, and Commander Holt is rescued and reunited with his children. Meanwhile, Lotor struggles to gain the upper hand in his duel with Zarkon, but ultimately defeats and kills Zarkon once and for all.

Following Zarkon's demise, the Empire is left in turmoil. Haggar recruits Lotor's former generals in her plan to keep Lotor off the throne (and presumably out of danger). Lotor informs the team that the Galra will be preparing for a coronation ceremony called the Kral Zera in the next two days, in which a new emperor or empress will be crowned. He stresses the importance of his presence there, and Shiro agrees, but everyone else is wary and believe it is too dangerous to plan a mission of that magnitude in such a short time. Shiro snaps at Lance and puts his foot down, accepting no questions on the matter. Later, Lance discovers a third form of his bayard, an ancient Altean broadsword which Allura tells him her father once wielded. She confesses her concerns about Shiro to Lance, who assures her that they both have the Coalition's best interests at heart. A Galra commander attacks the new Coalition capitol on Olkarion with a virus that infects the forest in an attempt to seize power. With Voltron on the verge of being captured, the Paladins use all five bayards simultaneously, allowing them to access the astral plane. Shiro only half materializes, calling out to Lance, who cannot hear him. When they successfully overcome the virus and return to the physical plane, Lance approaches Shiro about what he was trying to tell him. Shiro says he doesn't remember calling out to him, leaving Lance unsettled. Commander Holt tells his children that he's proud of them, but that he must return to Earth to prepare their planet for the coming war.

Keith and two other Blade of Marmora members infiltrate Planet Feyiv, where the Kral Zera will be held, with the aid of a Galra mole. Lotor explains the Kral Zera in greater detail, but the Paladins still disagree with his plan. Shiro storms off the bridge, and Hunk comments on how weird he's being. Keith and the two Blade members plant bombs in the underbelly of the ceremonial platform, above which a skirmish breaks out among the generals present. Haggar arrives with her generals and the commander she has chosen to delegate for the throne; Sendak. When it seems like Sendak will acend the stairs and light the Kral Zera, Lotor appears in the Black Lion with Shiro, who has gone behind the backs of the other Paladins and moved forward with Lotor's plan. Keith realizes Shiro's presence and scrambles to disarm the bombs, leaving the other Blade members to desert him. He is unable to disarm all of the bombs in time, and the consequent explosions interrupt Lotor's duel with Sendak, sending the ceremony into chaos. The other Paladins arrive in time to aid Shiro, and Acxa saves Keith from a rogue Galra commander. Lotor lights the Kral Zera and is officially crowned as the new emperor of the Galra Empire.

The team bids farewell to Commander Holt, and Kolivan sends Keith on a mission to destroy a super weapon that was being developed by a Galra commander named Ranveig and retrieve one of their operatives. Kolivan stresses the importance of destroying this weapon before it falls into the hands of either of the two warring factions, and warns Keith not to let his emotions cloud his judgement. Meanwhile, the newly crowned Emperor Lotor allows the team access to Galra headquarters, where he insists on asking Allura's help in looking over Haggar's research materials. Lance, Pidge, and Hunk reprogram their escort sentry and get up to several shenanigans which ends with their pursuit by other guards. Keith successfully meets up with the operative, Krolia, but their mission to destroy the weapon is interrupted by Commander Trugg, one of the faction leaders. Trugg captures Keith and demands their surrender, and to Keith's surprise, Krolia obliges in giving up the code to the weapon in exchange for Keith's release and their safe passage. Trugg immediately fires upon them once she has the codes, but Krolia assures Keith that Trugg is at the mercy of the weapon, not the other way around. The weapon turns out to be a ferocious biological monster. Once they're in the clear, Keith asks how Krolia was able to use his Marmora blade. She confesses that it used to be hers before she left it in the care of Keith's father, revealing her identity as Keith's mother.

Upon discovering a stone that contains a map to the mythical land of Oriande, the birthplace of Altean alchemy, Lotor convinces Allura and the team that they must travel to the Patrulian System, a deadly area long since deemed unsafe for navigation. While Coran expresses his concerns, Allura feels in her gut that this is the right thing to do, so the team agrees. They discover a white hole, a massive field of energy output that only Voltron can safely traverse. The Paladins attempt, but are stopped by a White Lion guarding the way through. The Castle of Lions and all of the Lions lose power and the Paladins are forced to manually evacuate. Lotor explains why his and Allura's Altean markings are glowing; they're Marks of the Chosen, designating them as the only ones worthy of crossing into Oriande. While the two of them navigate this uncharted land, the others struggle to try and get the Castle back up and running before they run out of air. Shiro pulls a distraught Lance out into the hallway and surprises Lance when he confesses that he doesn't recall anything from their stint in the astral plane and that he doesn't feel like himself. Meanwhile, Allura and Lotor both face off against the White Lion guardian, and where Lotor fights and is ultimately kicked out of the temple, Allura unlocks the secret to Altean alchemy already hidden inside her. They return to the Castle just as the others are about to pass out from lack of oxygen. Haggar spies on the team through Shiro and orders her generals to set a course for the Patrulian System.

Lotor discusses Voltron and the Empire's next move--Lotor insists that the Sincline ships are the utmost priority, while Lance tries to convince Allura that liberating planets should be the most important thing. Several factions of Galra are splitting off from the Empire, the most notable of which being The Fire of Purification, led by Sendak. Sendak launches an attack on a loyalist shield station, and Hunk, newly educated in Galra culture, leads the charge in the station's repair before the next radiation band annihilates the innocent people on the planet the station protects. Shiro suffers an attack during the repairs, causing the station's power to fail. Lance is almost killed protecting Allura from a catastrophic discharge, though she arrives in time to heal him and pull him back from the brink. They repair the station in the nick of time. Meanwhile, Honerva arrives at the gates of Oriande.

Stunned by the revelation about his mother, Keith demands answers, but Krolia reminds him that they have a mission to complete. En route, they are assaulted by mysterious creatures and are forced to ditch their ship or be torn apart by the space-time dropoffs. Forced to continue on foot, the two are caught in a blast of light that causes Keith to have visions of the past and future. Krolia explains that it was an example of time collapsing near the dark stars. Period flashes give Keith detail of how his parents met, how they discovered the Blue Lion, and ultimately why Krolia chose to leave. Similarly, Krolia discovers the fate of her lover and Keith's father. Hitching a ride on the back of a whale-like creature, Keith, Krolia and a cosmic wolf they adopted spend two years (several weeks for everyone else) within the warped time of the quantum abyss before they emerge on the other side to discover a well-kept facility, inside which they find an Altean. Meanwhile, Lance struggles to come to terms with his feelings for Allura and his jealousy of how much time she spends with Lotor.

A dwarf and a cleric are pursued by a vicious creature. Taking the crystal it dropped, the two venture to an inn to ask the innkeeper for more details about it, wherein they meet a paladin with a tragic backstory who offers to aid them in their quest. Upon leaving the inn, however, the paladin is devoured by a large rat. It turns out that Coran, Shiro, Hunk, and Pidge are all playing Monsters and Mana, and the large rat was just Platt chewing on Shiro's character token. Shiro insists on continuing as a paladin, much to the others' chagrin. Lance and Allura come to join them (the former reluctantly so), and they venture into the Tomb of Horrors. Together, they use their unique abilities to overcome the obstacles Lore Master Coran throws at them. Afterwards, Pidge and Hunk hurry off to continue repairs on the Castle, while Allura is called off by Lotor. Lance reluctantly joins Shiro and Coran for another round.

With the work on the Sincline ships done, Allura and Lotor make the journey into the quintessence field while the others wait nervously in the Castle of Lions. They're hailed by an unidentified craft, piloted by Keith, which Coran is shocked to learn is Altean in origin. Keith arrives with Krolia, the Altean they discovered, and the cosmic wolf he rescued on the space whale to tell them that Lotor has been lying to them all this time. Romelle, the Altean, explains that Lotor rescued any Alteans who hadn't been on Altea at the time of its destruction and created a colony for them to hide and live in peace. While many revered Lotor as a messiah, Romelle was skeptical, especially when many of her people and her own brother were taken to supposedly start a second colony. It is revealed that the second colony was a farce and that Lotor has been harvesting quintessence from thousands of Alteans. Betrayed when she learns this, Allura knocks Lotor out despite his pleas for her to listen to him. Honerva then unleashes her trump card on them all--Shiro. Under her control, Shiro makes off with the unconscious Lotor, Pidge unable to bring herself to apprehend him. Keith then reclaims command of the Black Lion and Voltron takes off in pursuit of Shiro and Lotor.

With Keith back in the Black Lion, the Paladins engage the Sincline ships piloted by Lotor's generals while Shiro escapes with an unconscious Lotor. Despite their efforts, they all escape via a wormhole conjured by Honerva, though Keith is able to make it through at the last moment. On the other side, Shiro hands Lotor over to the generals before being commanded by Honerva to lure Keith away. Honerva greets Lotor, revealing herself as his mother, but Lotor renounces her and refuses to accept or acknowledge her as his mother. Acxa, having been working with Lotor the entire time so that the Paladins would trust him, fires on Honerva, but she escapes. Zethrid and Ezor agree to work for Lotor again before all four leave in the Sincline ships back to the Castle. Everyone back at the Castle struggles against a virus, planted by Shiro, that shuts down the entire Castle and leaves them powerless. Meanwhile, Shiro leads Keith to a secret facility where Keith discovers various clones of Shiro before engaging him in battle. Keith is scarred in the fight, but is able to cut off Shiro's mechanical arm, which was causing Haggar to control the latter. As the facility crumbles around them, Keith tries to save Shiro, but the rest of the facility collapses and they begin falling while Keith remembers how they met and how Shiro promised to never give up on him.

Keith awakens in the astral plane, where he is greeted by the real Shiro. Shiro explains that after their battle with Zarkon when he disappeared, he actually died and his physical body was destroyed, but the Black Lion absorbed his spirit to save him. Back at the Castle, Coran works with the others on trying to restore the Castle. Lance comforts Allura over her hurt feelings and guilt of allowing Lotor to manipulate her. Keith, in the Black Lion, contacts them and explains that Shiro was a clone and that Lotor's Sincline ships are headed towards them. Realizing that he needs to get back into the Quintessence field, Allura decides that they must destroy the inter-reality gate. Lotor and his generals arrive shortly after and Lotor pleads his case with Allura, but she refuses to listen after everything he's done to the Alteans. When she says that he is just like Zarkon, Lotor snaps and orders his generals to destroy the Lions. Lotor's true colors begin to shine as he declares he will start a new Altea, one that never knows of King Alfor, Princess Allura or Voltron and where he is worshipped as their savior. When he declares he will wipe out all his enemies, including the rest of the Galra, Acxa, Ezor and Zethrid decide to leave Lotor for good and abandon the battle. However, Lotor ejects them from their ships and combines the Sincline ships into a Voltron-like mech that he can pilot by himself. Lotor's mech easily overpowers the Lions and severely damages the Castleship. Keith pleads with Shiro's spirit inside the Black Lion to help him reach the others. Shiro tells him to see the others through the Lion's eyes and Keith is able to activate the Black Lion's ephemeral wings, allowing him to arrive just in time before Lotor finishes the Lions. Now together, they form Voltron and prepare to face Lotor's mech.

Keith shuttles the clone Shiro to the Castle as the Paladins prepare to engage Lotor. It is a difficult battle, due to Lotor's mech's superior speed and evasion, but the Paladins are able to force him into a corner and gain the upper hand. Just before finishing him, Lotor's mech suddenly jumps into the quintessence field at will, making him even harder to attack while also replenishing his energy with quintessence. Realizing that the only way to defeat him is within the field, Allura opens a path into the field where Lotor waits for them. The quintessence keeps the Paladins recharged and empowers Voltron enough to match Lotor's mech, but they are still at a standstill. Allura realizes that the quintessence is negatively affecting them the same way it corrupted Zarkon and Honerva and that they must leave soon, with Lotor already going mad with power just like his parents. Allura uses her powers to empty all of Voltron's quintessence into Lotor's mech, overloading it. The Paladins escape the field before they can retrieve Lotor, leaving him to die and his damaged mech stranded in the field. When they return, Coran reveals that Lotor's constant jumping in and out of the field has caused various rifts in reality to form and that they will continue to expand until the entire universe is destroyed. Coran deduces that he could overload the teludav to seal all the rifts, but sacrificing the Castle in the process. With no other choice, the Paladins unload and evacuate the Castle. As the Castle enters the rift, the teludav overloads and the Castle is destroyed, but the rifts are successfully closed, leaving behind a single diamond as a result of the Castle being crushed by the sheer pressure of the rifts. After landing on a small planetoid, the Paladins try to help Shiro, whose spirit is within the Black Lion. Lance tearfully realizes that the real Shiro had tried to reach out to him, but he didn't understand. Allura uses her powers to extract Shiro's spirit from within the Black Lion and transfer it into the clone body, turning the rest of Shiro's hair white. As the Paladins decide what to do next, Pidge reveals that a copy of the plans for the Castleship were given to her father before he left to return to Earth. Keith declares that they are going home.

Following on from the sacrifice of the Castle of Lions, the Paladins and their allies need to figure out a way to recharge the Lions after their battle with Lotor. Shiro remains comatose after having his spirit from the Black Lion placed in the clone body. Coran leads a group including Hunk, Pidge, Lance, and Romelle in search of Yalmors to try and re-energize the Lions while Keith, Krolia, and Allura remain behind with Shiro. As Shiro sleeps, he remembers parts of his past, including his first meeting with Keith, sponsoring him to the Galaxy Garrison and becoming friends with him, his relationship with Adam, and his choice to go on the Kerberos mission despite being ill. The situation becomes worse when it becomes apparent that the clone body is rejecting Shiro's spirit and Allura is unable to do anything. As Coran and the others find a Yalmor, they are sprayed by a creature and shrunk but they are able to return to normal size using the same energy they were searching for to repower the Lions. Shiro manages to pull through before the rest of the team returns.

Although the Lions are not at full strength, the Paladins are resolved to head to Earth, a trip that will take one and a half Earth years. Pidge tries to contact the Voltron Coalition but has no luck. After having trouble sorting out who rides in which Lion, they eventually arrive at a Blade of Marmora outpost only to find it long abandoned. As they try to investigate, the Paladins are attacked by a small Galra fleet. However, with their underpowered Lions, the Paladins are outmatched by the Galra. The Paladins fly into a cyclone and use an ice planet to their advantage in dealing with some of the Galra, but are eventually captured by Lotor's former generals, Ezor and Zethrid.

The lions have been subdued by Ezor and Zethrid, who have become pirate warlords and the Paladins, Krolia, Romelle, and Shiro have been locked in the brig. Coran, having evaded capture, is assisted by the mice in subduing a Galra pirate and taking his uniform. Coran's ruse does not last long however, but Acxa appears and saves him. Together, they devise a plan to rescue the others and escape the pirate fleet. Ezor and Zethrid interrogate the Paladins on the result of their battle with Lotor and his subsequent fate, worried that if Lotor is alive that he will come after them for abandoning him. They leave when Acxa triggers an alarm and fires an ion cannon in the hangar, ejecting the Lions into space and forcing the ship into lockdown before confronting Ezor and Zethrid. The group is able to escape and retrieve their helmets and bayards thanks to the mice and learn through them that Acxa is helping their escape. Unwilling to leave her behind, Keith rescues Acxa from Ezor and Zethrid and they escape. Keith then detonates a group of explosives in the ship, badly injuring Ezor and Zethrid. Afterward, Acxa fills the team in on what has happened and they are shocked to discover that three years have passed since they fought Lotor. Acxa had chosen to find her own path and dedicates herself to helping the Voltron Coalition in any way she can, while the others ponder over what else has changed.

The Paladins inexplicably find themselves on a game show called "Garfle Warfle Snick" hosted by an alien named Bob. He challenges them to solve his various puzzles recapping their adventures while pitting them against comedic versions of their enemies. If they lose, they will have to stay in the game show for the rest of eternity. For the final challenge, Bob has each of the Paladins vote for one person who they think should escape from the show. When all of the Paladins vote for a different teammate (Keith and Lance voted for each other, Hunk voted for Allura, Allura voted for Pidge, and Pidge voted for Hunk), he deems them all winners and the show ends. All the Paladins wake up on their Lions shortly after and realize they had the same dream. Coran tells them he's heard legends of Bob, who is apparently an all-powerful, all-knowing interdimensional being who judges the worthiness of great warriors.

Pidge picks up a distress signal sent from what appears to be a senior member of the Blade of Marmora. The team heads to a planet and find a devastated set of ruins. They find a single alien, Macidus, who has several Marmora blades in his presence. Macidus fills the team in on events since their disappearance: with Lotor gone, the Galra Empire fractured, and Haggar's Druids set out on a mission to eliminate the Blade of Marmora. They drew the Blades to the planet and fought a vicious battle, with Macidus being the only survivor. While the majority of Macidus's story is true, Macidus is revealed to actually be one of Haggar's Druids, and the one who fought Keith years previously and has been using the signal to draw the scattered remnants of the Blades to the planet to kill them. Macidus uses his powers to freeze the team, but Keith's cosmic wolf, nicknamed Kosmo, teleports Keith away in time. They fight throughout the caverns, and find Kolivan alive. Meanwhile, Allura manages to free the other Paladins to join the fight and Keith kills Macidus. Kolivan is freed, and Krolia decides to join him in rebuilding the Blades as the Paladins continue on to Earth.

With the Lions not at their full power, Shiro suggests that the Paladins need to become a fully realized team to charge their Lions without the Castle's help. Before they can figure out a way to improve their teamwork, a storm appears that incapacitates the Lions and freezes everyone but the Paladins with a strong energy pulse. When they try to tether the Lions together, the storm appears again and separates the Paladins from the Lions, leaving them stranded in space. As the days continue, the Paladins start to lose their sanity and trustworthiness for each other. Hunk desperately tries to keep them together and stops them from falling for an illusion of Earth generated by a large manta ray-like creature. Hunk's bravery inspires the team to work together and the regained trust guides the Lions back to them. They are able to form Voltron once more and escape from the creature. They enter the storm again where the other passengers are restored back to normal, and they discovered that the storm has advanced their trip, putting them back in the Milky Way Galaxy.

As Voltron nears Earth, Pidge tries to contact her father and receives a recorded message from him telling them that the Galra Empire have invaded Earth, and they are preparing for their last stand. Four years earlier, Samuel Holt wakes in the Galaxy Garrison after being quarantined and is reunited with his wife, Colleen. Sam recounts his experiences with the Galra to the Galaxy Garrison's command staff, and warns them about a probable attack by the Galra on Earth. Sam advises them to warn the planet immediately but Admiral Sanda refuses to panic the world with the revelation of alien life. Commander Iverson and Sam begin analyzing Galra and Altean technology in an attempt to engineer new defenses for Earth. Sam meets the Garrison's top cadets – James Griffin, Rizavi, Kinkade, and Leifsdottir and they begin upgrading Earth's defense capabilities. A year later, Sam receives word from Matt that Voltron has disappeared, and that the Voltron Coalition is being targeted and wiped out by the remnants of the Galra. Admiral Sanda orders Sam to break all communication with the outside galaxy in order to hide Earth's location. Sam argues that they should tell the world about the Galra, but Sanda again refuses. Without authorization, Sam and Colleen broadcast the truth to the world. Sanda orders them arrested, but support comes in from around the planet. Some times later, Sam is testing a new particle barrier at the Galaxy Garrison when the Galra arrive and begin attacking Earth.

Sendak leads the Galra invasion of Earth. Admiral Sanda refuses to deploy the new MFE fighters, and sends out a standard response led by Adam, but the fighters are all killed. Sendak demands Voltron be surrendered to him, but the Garrison has no idea where they are.

The Galra continue to invade, and soon most of Earth is overrun. Only the Galaxy Garrison with its particle shields is able hold out, so Sanda finally allows the deployment of the MFE fighters. Combined with new base weapons, the Garrison manages to force Sendak's forces to retreat from their position. Realizing that they cannot hold their position without sufficient supplies, Veronica, Lance's sister, takes Griffin and his squad on a supply run to a depot. During the mission, she seemingly sacrifices herself to allow them to escape. Sendak destroys the communications grid and continues to subjugate the planet. Cut off, the Garrison continues work on the IGF-Atlas. Veronica returns to the Garrison, having made contact with a resistance network, who reveals that the captured population are being put to work creating weapons for the Galra. Low on supplies and morale, Sam gives a speech urging them all to keep fighting.

The Paladins race through the solar system en route to Earth, and finally contact Sam. Sam tells them to not bring the Lions to Earth because if Sendak knows they are there, he will threaten the population unless they turn them over. So, the Paladins leave the Lions near Saturn and steal a Galra patrol ship to covertly land on Earth. On the surface, they are attacked by a Galra force and are rescued by James Griffin and his squad who escort them back to the Galaxy Garrison. Lance and Pidge reunite with their families, but Hunk's family are among civilians captured. The Paladins are brought up to speed on the Galra's efforts on Earth.

Admiral Sanda wants to trade Voltron for the Earth, but the Paladins refuse. Using the information from the Castle of Lions, they build an AI version of Sendak using his memories and interrogate it to learn Sendak's tactics and eventual plans. This proves difficult for Allura, reliving the trauma of her homeworld's destruction, so she turns her attention on something else: creating a new arm for Shiro out of the Garrison's prototypes. Keith and Hunk head out to rescue Hunk's family, linking up with a resistance member. He shows them the work camp where Hunk's family but tells them there is currently no chance to rescue them. Hunk is able to see his family from afar and vows to rescue them.

While being fitted with his new arm, Shiro reacts negatively to it but is able to stabilize after Allura replaces the power source with the crystal from her circlet. Using knowledge from the AI, the Paladins present Sendak's strategy to the Galaxy Garrison command staff: using slave labor, he is constructing weapons at key locations around the planet that will help him to control the planet. In order to determine their strategy, a team of Paladins and Galaxy Garrison pilots are sent on a scouting mission. A ground team of Keith, Pidge, Allura, James Griffin, and Kosmo infiltrates the facility while a sniper team consisting of Lance, Hunk, Kinkade, and Veronica covers them. Pidge manages to get the information and learns that the facilities are building Zaiforge Cannons capable of destroying the planet. With the stakes high, the decision is made to attack all six bases at the same time: five lions to attack a facility each, and for the MFE fighters to assault the sixth. Four of the Paladins are delivered to their targets by an MFE fighter, with Lance being driven to his target by his sister, Veronica. All of the Paladins manage to call their Lions, but the target defenses are stronger than expected and the Paladins are unable to prevent the launch of the Zaiforge Cannons. It becomes clear that their plan has been leaked – Admiral Sanda has reached an agreement with Sendak to hand over Voltron in exchange for Earth. The Paladins converge in Earth's atmosphere and form Voltron, but Sendak fires the Zaiforge Cannons at them, dispersing Voltron, knocking out the Paladins, and leaving the Lions out of power.

The Paladins are captured and incarcerated aboard Sendak's ship while Sendak continues his assault on Earth, despite Admiral Sanda's pleas that they had a deal. Sanda is sent to the cells with the Paladins. At the Galaxy Garrison, Shiro suggests taking the offensive. If they transfer all power, including that powering the particle shield, to the IGF-Atlas, they might be able to get it powered and flying. The MFE fighters provide cover while Shiro, Coran and Sam try to get the Atlas airborne. After a failed attempt, Coran realizes the crystal formed from the destruction of the Castle of Lions could be the key and inserts it in the ship. It instantly powers the ship and the Atlas launches and joins the fight. Aboard Sendak's ship, the Paladins use their connections with the Lions to telepathically control them. When Sendak realizes what they are doing, he sends his Lieutenant, Hepta, to kill the Paladins. Admiral Sanda manages to get free and almost stops Hepta, but is mortally wounded in the process. The Paladins use the Lions to free themselves and join the battle, and the Black Lion kills Hepta. Sanda begs the Paladins to save Earth when she could not and dies.

Voltron begins to turn the tide of the battle in Earth's favor, but Sam soon realizes Sendak's plan. Using the Zaiforge Cannons, Sendak intends to combine their beams to destroy the Earth. Voltron tries to destroy Sendak's command ship, but soon find that the cannons' launch facilities were also designed to defend the cannons from the surface. Pidge proposes a plan to use the orbital reflectors that the Galra use to deflect the beams of the Zaiforge Cannons in an effort to deflect the beam away from Earth. While they move the reflectors into position, the MFE fighters launch on a mission to take out the launch facilities one by one so as to remove the Galra's ground support. The Paladins successfully deflect the beams from the Zaiforge Cannons, but the constant fire eventually causes them to buckle and break. The IGF-Atlas intercepts the beam, while Shiro infiltrates Sendak's ship and disrupts the control crystal. Shiro's efforts give the Paladins enough time to destroy the Zaiforge Cannons while the MFEs finish destroying the launch bases. Sendak's ship plummets towards the Earth. The Lions guide the ship into an uninhabited area while Shiro and Sendak fight. Sendak gets the upper hand and looks to kill Shiro, but Keith arrives and kills Sendak. The Paladins' victory is short-lived, however, as a meteor falls to Earth.

Just after Sendak and his forces are defeated, a powerful enemy robot arrives from space to fight the Paladins. Despite the Paladins' best efforts and the support from the Atlas, the robot takes down Voltron and drains its energy, in a manner similar to that of Haggar's Komar device. Just as the robot is about to destroy the Paladins, Shiro learns to use the power of the crystal to convert the Atlas itself into a massive robot that dwarfs Voltron. The enemy robot then fights the Atlas and incapacitates it, but the Paladins take the time to recompose and devise a plan to fight back. Realizing that the enemy robot's weak point is in the chest, the Paladins succeed in defeating it, but then the robot prepares itself to self-destruct, and the Paladins use their Lions to lift the robot to space, where it explodes from a safe distance. After the battle, the Paladins recover at the hospital surrounded by their families and friends, and eventually, all the remaining members of the Voltron Coalition (including Shay, Matt, Nyma, Krolia, etc.) arrive at Earth, not only to help rebuild it, but also to make it their main base of operations against the Galra Empire. Months later, after the Garrison had retrieved most of the remains of the robot, Allura is shocked upon learning that a female Altean was discovered inside it as the power source.

Six months have passed since the defeat of Sendak and the mysterious Robeast. With the Atlas and Voltron preparing to leave Earth to liberate the rest of the universe from the Galra, Hunk pushes Lance to ask Allura out on a date, which he manages to do. Pidge, Romelle, Rizavi and Leifsdottir help her choose a dress for the date while Lance is ordered by Coran to follow Altean customs. Prior to the date, Keith gives Lance a pep talk, reminding him that Allura agreed because she liked him. Allura joins Lance's family for dinner and they later kiss. Meanwhile, the comatose Altean, Luca, wakes up. She accuses Romelle of being a traitor and mentions that Honerva sent the Robeast before Honerva telepathically kills her. The next day, Voltron and the Atlas leave Earth.

In the past, Honerva reveals to Zarkon that she is pregnant with their child, whom they name Lotor after Lotarious, a figure in Altean history, and Kaltor, a figure in Galra mythology. After the destruction of Daibazzal, Honerva has lost all her memories and assumes the name "Haggar", taken from a Galra medic sent to attend to her that she instead kills. She later gives birth to Lotor, but does not acknowledge anything until Zarkon questions her about Quintessence. From there, Lotor grows, excelling at his academic and strategic studies despite his smaller physical stature for a typical Galra. He inquires about his mother, but Zarkon refuses to speak anymore of her. When Lotor is slightly older, he takes possession of Honerva's old cat, Kova. Many years later, Lotor receives his father and Haggar at a planet under his dominion, but Zarkon is disgusted that Lotor chooses to work alongside the local populace rather than subjugate them and has the planet destroyed and Lotor banished. In the present, Honerva desperately tries seeking Lotor and eventually discovers his battle with Voltron in the Quintessence field. At the next Kral Zera, Honerva reveals herself and kills all those in attendance before arriving at the Altean colony Lotor had started. After revealing herself as Lotor's mother and that Voltron killed Lotor, the Alteans swear their allegiance to her. They travel to Oriande where they restructure the planet and build several Robeasts before sending the first one, piloted by Luca, to Earth.

The Paladins and Atlas attack a Galra base run by Warlord Lahn, whom the Paladins had previously helped aboard the Omega Station. Lahn, however, rebuts any of their attempts at becoming allies, due to feeling abandoned by Voltron after making their alliance when Sendak attacked them. An alert from Lahn's missing fleet that had gone to salvage weapons from another base comes in and he is taken with the Paladins to investigate. They discover the wreckage of the entire fleet, caused by the superweapon created by Warlord Ranveig, that Krolia had previously set loose to allow her and Keith to escape during their first mission together. They are able to destroy the creature by setting the ship to self-destruct and Lahn, finally convinced of the Paladins and their heroism, agrees to join the Coalition and urges other Galra to do so as well.

The Paladins split up from the Atlas to search for signs of another Robeast, similar to the one that attacked Earth, but find nothing for days. When they decide to stop at Olkarion, they discover that the planet is lifeless and about to be consumed by a Weblum. While Keith, Lance and Hunk hold it off, Pidge and Allura try to find out what happened. By tapping into her connection with nature and the Olkari, Pidge is able to see the events that transpired: a Robeast arrived on Olkarion, attacked and stole the Olkari cube weapons built by Branko. The planet was unable to survive the attack due to its Quintessence syphoning abilities, and the Olkari were forced to evacuate their planet. The Weblum begins consuming Olkarion, but Pidge is able to acquire useful information from the Olkari in tracking the Robeasts.

Acxa struggles in adjusting to the Atlas crew, remaining aloof and distant until she finally feels accepted by Veronica. Meanwhile, the Paladins and Atlas plan to meet up, but when the Paladins arrive at the meeting place, they are ambushed by a Galra ship. Forced to abandon their lions and suits, they struggle to survive without weapons or armor in a toxic environment that will slowly kill them. The Atlas eventually figures out the ruse and arrive in time to help Lance, Allura, Pidge and Hunk. Keith, however, is attacked by the group's leader: Zethrid, who wants revenge on Keith for what he did to her and for taking Ezor from her. She overpowers Keith just as the Atlas crew arrive. Acxa tries to reach out to her former friend, telling her that Ezor left her because of all the hate and anger Zethrid held onto. Zethrid is subdued and imprisoned on the Atlas, where Acxa refuses to give up on her friend as Ezor appears beside her.

The Atlas heads to Oriande to confront Honerva and her machinations. Honerva sends Robeasts to various planets to syphon their Quintessence and send them into the Olkari cubes to amplify their power. The planets are successfully evacuated in time, but Honerva sacrifices the White Lion in order to bring back Lotor's Sincline mech from the Quintessence field. Allura, fueled by rage, coldly attempts to kill Honerva, but Honerva threatens to destroy Lance and the Red Lion, causing Allura to miss. Honerva flees Oriande as the planet becomes unstable and the white hole leading to it begins to close. The Paladins and Atlas are able to escape just in time, but despair at not being able to stop Honerva.

Kinkade, one of the MFE fighter pilots, documents day forty seven aboard the Atlas to show what it is like. Rizavi, seeing what he is doing, joins in to make a more exciting movie. They interview various members of the crew such as the Paladins, Kolivan, Coran and Colleen Holt while the camera gets lost during a battle and found by Bae Bae, the Holt family dog, and the Space Mice. During this time, the Atlas has captured a sixth Altean pilot of the Robeasts, but all refuse to speak to Allura and Romelle. Later, Kinkade documents Hunk's attempts at making an Altean cake in order to get the Alteans to open up. It is successful and they agree to speak with Allura and Coran.

Tavos, one of the Alteans, speaks with Allura, but when Honerva interferes, Allura is able to extract a small, dark creature from him, which is what allows Honerva to spy through and control them. The creature is contained for the moment while the Atlas investigate increased activity on a planet. This planet turns out to be the same one from the Voltron Show tour that Coran had gotten the date wrong, as the citizens can only come out on one day per year when the weather is clear. Despite still being angry over their failure to show up, the leader invites them to attend as free security. Everyone heads down to enjoy carnival festivities while Allura stays behind to rest. Keith and Hunk get stuck on a ride, Coran wins a Yalmor imitation contest, Lance and Pidge both try to win prizes for Allura while Shiro wins an arm wrestling contest and defeats the reigning champion: a reformed Beta Traz Warden. As she is resting, she is tormented by haunting visions of Lotor, Lance and her own mother, all convincing her to use the dark creature to stop Honerva. She gives in and allows the creature to fuse with her body, and passes out.

When Allura wakes up two days later, she decides to use the dark entity to her advantage. Despite disapproving of Allura's decision to take in the dark creature, the team nonetheless decide to use its connection to Honerva to see into her mind and hopefully figure out her plans. As they reach Honerva's mind, all the Paladins - except Keith - are pulled in and forced to fight corrupted versions of the original Paladins. Once defeated, the original Paladins are restored and freed from Honerva's corruption. Paladins old and new reunite outside Honerva's mind and Allura is reunited with her father. Despite his warnings of the dark creatures and how they led to Honerva's corruption, Allura presses on and they are able to enter Honerva's subconscious.

As they travel deeper into Honerva's mind, they are attacked by the Robeast Myzax, one of the guardians installed to protect Honerva's secrets. The old Paladins hold it off while the new Paladins press on and discover more about Honerva's past and how - as Haggar - she killed Gyrgan, Blaytz and Trigel. They keep going and encounter a second guardian in the form of Zarkon's Robeast armor. The old Paladins arrive to help and once it is defeated, it reverts to an uncorrupted Zarkon. They discover that Honerva's desire is to be reunited with her family. However, because Zarkon and Lotor are both dead, they deduce that she plans on using Lotor's Sincline mech to pierce into another reality where she can have her happy ending. Doing so, however, will result in the destruction of other realities. Honerva becomes aware of their presence in her mind and the Paladins are able to escape with the help of the old Paladins. However, when the new Paladins return to the real world, Allura is comatose.

The Atlas crew race to stop Honerva, who uses her own mech to search for the reality where she can live happily with her family. Using the dark creatures, Honerva takes control of the Alteans aboard the Atlas, and uses them to siphon and channel the energy from the Castle of Lions crystal that powers the Atlas. Merla, one of the Robeast pilots, is horrified at Honerva's willingness to sacrifice her fellow Alteans, and turns against her. Lance is able to bring Allura back from her coma. Hunk arrives with a Balmera, but Honerva siphons its energy as well, allowing her to fuse her own mech with Lotor's Sincline.

Despite their efforts, Honerva is victorious and opens a rift in reality. Since Voltron is made of the same material, only it and not the Atlas can follow after her, but they do not stand a chance against Honerva's fused mech. Several more Balmera arrive and imbue Voltron and the Atlas with enough energy to fuse them together, allowing them to pursue and match Honerva. The Paladins and Shiro enter the rift while Coran tries to think of a way to stabilize it. Coran has each of the Alteans placed on a Balmera to channel energy to stabilize the rift, with the Galra fleet led by Krolia and Kolivan arriving as well to provide aid. Voltron-Atlas continues pursuing Honerva through various alternate Alteas, each of which is crumbling into nothingness as a result of Honerva's tearing apart of reality. She arrives at her destination, appearing before Zarkon, who is elated to see his wife back, as Honerva had died in that reality. They travel to Altea, where a young Lotor is being raised in accordance with Honerva's wishes, but Lotor rejects her, knowing that she is not really his mother. When Honerva shows her true evil colors in her angry response to Lotor's rejection, Zarkon also declares that she is not his wife and calls for her to be arrested. Voltron-Atlas arrives and, heartbroken and angry at their rejection, Honerva decides to destroy all realities.

Voltron-Atlas engages Honerva's mecha in the alternate Altean reality. Honerva gains the upperhand and travels to the source of all realities. Enraged by her loss, Honerva coldly eliminates each and every reality from existence. After a desperate battle, they are able to stop Honerva from destroying the last reality. They work to convince her that while life is hard and rough, it is still gorgeous and vibrant, something Allura reminds her of by showing Honerva her memories. Allura convinces Honerva to help her undo what she has done and repair the damage, knowing that it will require both of them to sacrifice their lives. After saying a tearful farewell to the team, and giving Lance Altean markings, Allura and Honerva sacrifice their lives to restore all the destroyed realities. The original Paladins and Lotor appear and Allura and Honerva move toward them, signifying their deaths. The team find themselves in their home universe with Altea and Daibazaal restored.

One year later, Keith declares that the Galra Empire shall be restored to its former peaceful glory before Zarkon's rise and that they will join a new Galactic Coalition being formed with Earth at its center. Pidge is working with her brother to create a robot named Chip while her father is perfecting Teluduv technology while also using the Green Lion for it. Later, Pidge travels to Altea for the first celebration of Allura's memory. Coran has been overseeing reconstruction of a new Castle of Lions with Merla's help and organizes a dinner in front of the statue erected in Allura's honor. That night, the Lions of Voltron, their long task now finished and the universe at peace, share a silent farewell with the Paladins and leave for parts unknown.

Following this, the Holts work to create the next generation of Legendary Defenders. Hunk began a culinary empire, bringing races together one meal at a time under the philosophy that full stomachs brings happy lives. Lance is spreading Allura's message of peace and togetherness while also working on the family farm. Kolivan and Krolia become the Galra representatives of the Galactic Coalition while Keith turns the Blades of Marmora into a humanitarian relief organization, with Acxa, Zethrid, and Ezor among its ranks. Shiro retired from fighting and married an Atlas crew member, Curtis. In a post-credits scene, the lions fly through space with a silhouette of Allura among the stars.
