Voltron: Defender of the Universe Episode Rating Graph

Voltron continues the attack on Planet Doom with Merla's help. This time, Lotor is by her side, ready to take on his father and lead Voltron though Haggar's traps.

The evil Rogue Galaxy barbarians have started an all out war against the Alliance. Princess Allura, Keith, Sven, and the rest come to speak at Galaxy Garrison's intergalactic council. But then Lotor crashes the conference, and Allura surrenders herself to save the others. Now the team has to move into action, but who will pilot the Blue Lion?

The Voltron Force successfully ground 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.

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.

A crack team of pilots is selected by the Galaxy Alliance to travel to Planet Arus and uncover the secret of a weapon from ancient times, Voltron!

The Muses of Norn escape from Merla and reach Galaxy Garrison safely. Not only that, but they've managed to bring Merla herself as a prisoner. They'll only turn her over to a high ranking official, so Prince Bandor goes. Then Queen Merla springs her trap with the help of Lotor. The Voltron Force must rescue Bandor while fighting two evil starfleets at once.

Keith, Sven, Pidge, Hunk and Lance scour the surface of Planet Arus, looking for brave citizens willing to help them fight Zarkon.

Keith, Lance, Sven, Hunk and Pidge ask for help from the Princess Allura to find Voltron.

With Zarkon and Lotor recovering from their big defeat against Planet Arus, local Drule warlord Cossack makes his move for glory. He assaults Planet Pollux, and manages to corner Bandor. Sven signals the Voltron Force and rides out on his horse to save the young prince. Keith and the others arrive to find Cossack working alongside an old enemy, who has a deadly trap waiting for Princess Allura.

All at once, Zarkon's countless slave planets begin revolting at the same time. The evil King's armies are spread thin, and the Alliance stages a major offensive. Princess Allura and the Voltron Force once again take the fight to Zarkon. Zarkon fights back by trying to sacrifice Prince Lotor, but Merla has a change of heart and protects him. Then she begs the Voltron Force to help her save Lotor from the Pit of Skulls.

Coran is showing the Voltron Force space images of the planet Philos - an oddity in that it's a planet that orbits and acts like a comet. Ineterrupting their space lesson is a skull tank, which lands on Arus with a white flag raised. Though skeptical, the team has to check it out. Alliance guards escort the pilot of the tank out, which is an alien who claims to be from Philos. Lance wants to just lock him up right away, but Allura gives the stranger a chance.

On Arus, a parade is going on complete with floats containing statues of all the important people like a dead king, a princess and an advisor...but no statues of the voltron force save for Keith. This doesn't sit well with the other four guys. Merla sits on Zarkon's throne plotting her next move on Arus. Haggar tries to sneak a mini-spider robeast in to attack Merla but her vulture pet comes to the rescue, giving Haggar a bitter taste of her own medicine. To keep Merla from putting her little robeast in the cosmotron - that contraption that makes stuff disappear - Haggar promises to help Merla defeat Voltron.

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.

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 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.

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.

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.

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.

A ship of young pilots from Galaxy Garrison crash lands on one of Zarkon's slave planets. All are enslaved except for Lt. Lorn, who is saved by a tribal girl with a grudge against Zarkon and a mysterious Fish Man. When Voltron arrives to free the young pilots, a Robeast attacks. The Fish Man is revealed to be one of Haggar's failed experiments. He grows to Robeast size and its' a Robeast versus Robeast battle to save the planet!

One of Zarkon's captains is imprisoned after he takes pity on some slaves. Now he's a slave alongside those he once oppressed. As they work on an alien planet, he is saved by a race of natives who live underground. When the Voltron Force arrives, they decide to sneak in and free the slaves. But that's impossible without someone who knows the complex. Can they convince the former captain to help?

Zarkon is annoyed at all the happiness on Arus, so in the dead of night, he sends out a Robeast to start destroying Arusian cities. The Castle's alert sirens go off and it isn't long before the VF launch into action. This crab-like Robeast is a real challenge. What's worse is they're hesitant to use Voltron as the monster insists on staying in the city where frightened Arusians could be hurt by the resulting battle. The VF try to lure the Robeast away but he won't budge, and Pidge only succeeds in getting his Lion skewered by the Robeast.

Yurak's fleet shoots down a space ship over planet Aurs. Hunk manages to rescue the pilot, a pretty young slave who escaped from Planet Doom.

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.

Lotor once again is up to no good. First he conquers a new planet and dubs it Zarkonia. The people of Zarkonia are promptly enslaved and treated poorly, which Lotor hopes will draw Voltron...for he and Haggar have a little trap for their loathed arch enemy when he arrives.

Sick of his son's failures, King Zarkon himself steps in and puts all his resources behind a huge plan to wipe out Planet Arus. Using the power of a hidden Lazon satellite, Zarkon plans to turn all 500 of his remaining gladiators into an army of Super Robeasts! But Sven gets wind of the plan, and infiltrates the armies of Planet Doom at great personal risk. Sven must find the satellite's location so Voltron can destroy it before it's too late!

A series of unnatural earth tremors frightens the Space Mice into action. Rather than running or hiding, they begin to train like soldiers, and fight a pitched battle against the Blue Cat. The back them up, Pidge builds them their very own robot vehicle, a flying mouse. Voltron is trapped by a powerful underground Robeast and it's up to the Space Mice to launch a rescue mission!

With Planet Doom's recent defeats, Princess Allura decides the time is right to strike back. She holds a conference for all the neighboring planets to discuss uniting against Zarkon. Lotor attempts to disrupt the meeting, and ends up slashing Keith across the chest. Allura must pilot the Black Lion to protect the conference from an enemy Robeast!

Lotor's newest Robeast generates an enormous cloud of fire and heat, vaporizing all the water around the Castle of Lions, including the entire moat. The Voltron Force is interrupted from their martial-arts training, and head off to battle. Princess Allura can't seem to activate the Blue Lion. Her father's ghost reveals the secret of the Lions: They are powered by the elements of Arus. Without any water, the Princess has no way of operating the Blue Lion, and the team can't form Voltron.

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.

To celebrate the rebirth of Planet Arus, Princess Allura decides to host the Space Olympics. Hunk and the rest of the Voltron Force mobilize an enormous construction machine to build the Grand Stadium in time. Lotor manages to take control of it, but Voltron can't fight back, because three local kids are trapped inside.

Zarkon is furious with Lotor's cowardice, and demands that he lead an attack on Arus from the front lines. Haggar creates a clone of Lotor that has no fear whatsoever, and sends it with a new Robeast that can generate a computer destroying electro-magnetic pulse. The EMP shuts down Voltron, so Keith sneaks out to sabotage the Robeast. Separated from the others, he is locked in a duel with the fearless, relentless Lotor clone!

Lotor, Zarkon and Morgill are watching some of the up and coming pilots in the Academy practice when a stand-out performance from one catches their eye. The pilot, Carp, does a bold fly-by at the trio before landing. Morgill wants to kill him for his wreckless endagerment of the King, but Lotor sees the potential in his skill as a pilot and has him spared after Zarkon seconds that notion. Carp is willing to pilot a robeast for Doom but insists it be built to his specs and, when he defeats Voltron, demands to be made Governor General of Arus. Morgill has never been more infuriated but must hold his tongue and his sword.

Instead of your typical Robeast, this time Haggar and Lotor have cooked up an elite fighting force of robots they call the Red Berets. Even Zarkon is impressed with their fighting style when he sees them in action at the Arena. The force of about 5 Berets is launched to Arus with a Robeast overnight.

Planet Arus has an evil twin planet, Pollux, that has allied with Zarkon. The Voltron Force travel to Pollux in an attempt to make peace.

After the battle on Planet Pollux, Romelle was taken prisoner by Lotor because of her resemblance to Princess Allura. She survives terrible hardships in the slave dungeons of Planet Doom, but finally escapes, crashing on the ice planet of Neeve.

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.

After a serious defeat at the hands of Planet Doom, the Voltron Force desperately trains, hoping to find a new source of strength before Haggar's robot attacks again. With help from the ghost of King Alfor, Keith and the others reach a new level of control over Voltron and unlock a new weapon!

Pidge naively helps some local kids collect tadpoles, so they can take them home and watch them grow. However, these tadpoles grow up to be horrible Robeast frogs surprising the kids at home and other innocents all over Planet Arus! The Voltron force splits up in a desperate scramble to save the populace from the deadly frogs.

A remote planet named Yadil has thrown off the bounds of Zarkon's oppression. They decide to join the Alliance, and invite Voltron to a celebration in honor of this great event. However, Voltron shows up strangely early, and with him a strike force of Doom Soldiers. They take over Yadil and set a trap for when Keith and the rest of the team arrive with the real Voltron.

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.

To celebrate his birthday, Lotor takes a trip to planet Tyrus. While getting a massage from scantly clad servants, Zarkon informs Lotor that he sent a ship with a present for Lotor ( a big gold statue of the Prince, to be exact). However, the ship ran into some trouble on its way to Tyrus and as luck would have it, the Voltron Force picked up the S.O.S.

Zarkon has decided it's time for Lotor to take a suitor and presents him with Princess Koral from Demos. He kisses her (a taste test?), and while she's attractive enough, Lotor just can't shake his dream of having Allura all to himself.

Unable to contain his ambition, Lotor challenges Zarkon to a duel in the arena. The winner takes the throne of Planet Doom. Witch Haggar takes the opportunity to steal the spotlight and field her anti-Voltron robot, programmed to steal the spotlight and exploit Voltron's weaknesses. Concentrating all its fire on Blue Lion, the robot successfully hands Voltron his first defeat!

Princess Allura, unsure of her ability to lead the planet, is visited in her dreams by the ghosts of her parents.
