Voltron: Defender of the Universe - Season 1

The Planet Arus has been under attack by the ruthless King Zarkon for many years. Responding to a call for help, Galaxy Garrison sends a team of five young space explorers, Keith, Lance, Sven, Hunk and Pidge, hoping they could reach the devastated planet, in hopes to offer help. However, they are captured by Yurak before they could land on the beautiful planet. Knowing that they would be used as entertainment for the citizens of Doom in Haggar's Robeast arena, they work out an escape plan, to find a way out of the Doom Castle and a way to get back to Arus. Hunk's brute strength and Pidge's agility, they are able to break out of their meager cell and hijack a Doom Slave ship. Pursued by Doom Robot fighters, the five explorers managed to reach Planet Arus. They then recall a legend of a mighty robot, named Voltron that once stood and fought against the forces of Doom. Though defeated, whe King Zarkon's witch, Haggar disguised herself as a beautiful goddess, then split the giant defender into five lion ships, sending the robot lions crashing to Arus' surface. The five explorers then vow to find a way of learning the secret to Voltron, in hopes to resurrect the mighty robot, and save Arus from the forces of King Zarkon.

After escaping from Planet Doom aboard a stolen slave ship, the five space explorers are chased to Planet Arus by Yurak's forces. Crash landing on the worn torn planet, the five youn men find themselves unwelcomed by the citizens, who are afraid of what will happen to them. The slowly make their away across the desert to the ruined castle, in hopes that they will be able to find the secret to the legend of Voltron. There, they are greeted by Coran, the Castle Magistrate, who relates to them, the story of how Arus was once a beautiful planet within the Diamond Galaxy, and thusly destroyed by King Zarkon's forces. He however, looks over the young Princess Allura, the last survivor of the royal family and daughter to King Alfor, the man who created Voltron. The five space explorers vow to help resurrect the fallen robot defender and to help protect Arus against King Zarkon's forces. With Yurak adamant on finding them, Coran tells them of the locations of each Lion robot, in hopes that they will uncover secret to join them together to form Voltron

Angered by Yurak's failures, Zarkon tasks his evil witch Haggar to send a robeast to Planet Arus, in hopes of capturing the five space explorers who escaped him and destroy what was left of any hopes to resurrect Voltron. Haggar sends her best robeast to Arus. On Arus, the newly formed Voltron Force watches helplessly as Yuraks forces attack Arus, while Coran reluctantly keeps the secret of the Lion ships to himself. Pidge decides to head out by himself to see exactly how near Yurak's forces are getting to the castle. Coran then reveals that the only way to activate the slumbering machines, is to locate the 5 mystic keys that can operate them. To Allura's surprise, he tells them that the keys were entombed with her father, the late King Alfor. Together, the members along with the Princess, make their way to the where King Alfor is entombed, and upon etnering the crypt, King Alfor's ghost makes his presence known to them. He shares with them his appreciation that five young strangers are willing to devote their lives to the protection of Arus. Unfortunately, to their dismay, only four keys are found with King Alfor, meaning that Voltron can't be formed, since the key to the Black Lion is missing. Reluctantly, the team take the four lions ships; Blue, Red, Yellow and Green , hoping to thwart the forces of Yurak. They are able to take out the many robot fighter ships and troops, but when Haggar's robeast finally lands on the planet, they soon realize that they are not prepared to handle a fight of this magnitude. Coran and the Princess watch in horror, as their new friends were easily defeated by the meanacing robeast.

Zarkon is angered that both Yurak and Haggar have failed in their attempts to bring back the escaped space explorers from Planet Arus. Haggar reassures Zarkon, that her robeast will be able to destroy the Voltron Force before they are able to find the missing key to the Black Lion. Pidge, slowly makes his way back to the Castle of Lions, where Coran and Princess Allura are worried that the five young men have just risked their lives in a failed attempt to bring back the legendary defender. On his return, Pidge makes his way back to the control room where Coran delivers the bad news. However, hope returns when Keith, Hunk, Lance and Sven recover from their ordeal and return to the castle. Still, the key to the Black Lion is still missing, so they make one last attempt to find it. Upon returning to King Alfor's tomb, they discover that there was a small mouse hole in the stone coffin. Pidge suggests that they capture the space mice he ran into earlier, in hopes of discovering the location of the missing key. They capture the four mice, and decide to question them about the whereabouts of the key they took. Allura however, interrupts them, asking them to let her friends go, revealing that the mice were the only creatures that gave her comfort in her years of being alone. On their suggestion, Allura questions her friends and learn that they took the key because they thought it was pretty. Making a deal, they release the mice, and they return with the key to the Black Lion. Just in time, the Voltron Force then launch to confront Haggar's robeast. The robeast puts up a great fight, and prevents them from forming Voltron, but on their second attempt, they are able to break free from the robeast attack and form the legendary defender. By forming the Blazing Sword, they are able to destroy the robeast.

Defeated by the Voltron Force, King Zarkon grows wary of his charges continuous defeat against the mighty robot defender. Haggar suggests that they hold a contest between her robeast monsters to determine one that would go to Arus and battle against the Voltron Force. They hold a battle and one such monster suceeds against the other monsters. Haggar then turns him into a giant robot monster, and sends him with Yurak and his forces to Planet Arus. On Arus, the Voltron Force are seeking help among the citizens of Arus, hoping that they will be brave enough to come out of hiding. Though, the people are still afraid and refuse to come out of hiding. It is then that Yurak attacks Arus, so the Voltron Force launch their lion ships. Quickly they realize that this robeast monster is much stronger and faster than their previous encounter and quickly lose their advantage. While the monster confronts Voltron, Yurak takes the opportunity to attack the Castle of Lions directly. Allura and Coran flee to the underground tomb of her father, there his spirit reveals a secret. Allura presses a button in the crown of his tomb and suddenly, a new and improved castle emerges from the ruins of the old one. Princess Allura comes to the aid of the Voltron Force by taking up one of the gun cannons on the side of the new Castle. There she wards off Yurak's attack with direct hits to his ship, then focuses her attack on the robeast. This gives the Voltron Force their opening to attack the monster and then destroy him.

With the new Castle of Lions and the return of Voltron, the citizens of Arus come out of their hiding places, comfortable to know that Voltron will protect them from the evil forces of King Zarkon. Princess Allura vows that the Voltron Force will protect her people and planet. In celebration of their new found freedom, she proposes a banquet. King Zarkon is not pleased that Planet Arus is slowly slipping away from his grasp. Haggar proposes a new plan, that in order to weaken Voltron, they need to do away with one of the Voltron Force members. Without all five of them, they would be unable to form the mighty robot. King Zarkon agrees, and the Witch Haggar goes to Arus, with one of her deadly robeasts. On Arus, the Voltron Force go with Princess Allura to pass out food to many of the destroyed villages, hoping they can bring more of the citizens out from hiding. Witch Haggar watches them closely, then tasks her Blue Cat to lure one of the members into her trap. Pidge is alerted by Cheezer that the Blue Cat is nearby. Lance and Sven then chase after the cat, where Lance falls into the Witch Haggar's trap. Sven rescues Lance from the trap, and battles Haggar alone. Unfortunately, Haggar's magic is enough to overcome Sven's abilities and he is then blindsided by her robeast monster, injuring him. Keith and Lance arrive too late, only to find Sven badly hurt. Keith suggest that they send him to Planet Ebb, where he can rest and recover from the attack. Now, one member short, the Voltron Force must deal with Haggar's monster without Voltron. They lure the giant beast to the edge of a cliff, overlooking a lava stream. Lance suggests that they attack the monster and force it into the firey stream. Lance volunteers to attack the robeast head on, since his Lion is homed in the lava pit that surrounds the Castle of Lions. Their plan works! They are able to defeat the robeast without Voltron and celebrate their victory. However, they do know that without Sven and the Blue Lion, Voltron will not be able to protect Arus from any further attacks from Yurak and King Zarkon.

It would seem an intruder has gotten in the castle, but it's not until after Pidge attacks the intruder that they learn it's really the Princess' governess who has returned.

The Princess is undergoing rigorous training in her Lion, fighting with Lance's Lion as if it's a real battle after taking a hard hit from one of his assaults, the Blue Lion plummets toward earth in a tail spin. She is saved, not by any of the VF rushing to aid her in their Lions, but by the tractor beams from a ship piloted by a mysterious stranger.

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!

Princess Allura, unsure of her ability to lead the planet, is visited in her dreams by the ghosts of her parents. When a majestic White Lion appears to her, she follows it deep into the forest, believing it to be the reincarnation of her father. Keith, Lance, Pidge and Hunk hurry to find the Princess before she falls into a trap!

A young girl named Tammy gets separated from her mother, and Pidge does his best to comfort her.

This one starts with Princess Romelle of Pollux being tossed into a dungeon cell on Doom by Prince Lotor. Due to her resemblance to her cousin Allura, Lotor figures he might as well live vicariously through her and snag a smooch. Of course, he is seriously denied when she sends him packing with a hefty slap to the face. She even tries to stab him with a sharp rock. Poor Lotor, he gets no respect.

Lotor is daydreaming of Allura once again when Zarkon summons him. Planet Moura has been captured and it's time to have a little arena fun with some slaves. Zarkon also has a new toy he wants Lotor to tend to - it's an Ion Laser Gun that will be powerful enough to obliterate Arus when finished. Meanwhile, Voltron is lurking in an asteroid belt so the VF can keep tabs on the activity on Moura, as well as observe Zarkon's other new toy - the Centipede Express. Upon deciding reconnosence is in order, Keith and Lance use Green Lion's head to fly down to the planet's surface. Armed with explosives, they aim to strategically place them around the giant Ion gun in hopes of destroying it. By knocking out a few Doomite guards, they score the perfect disguises to proceed in.

Yurak is leading a fleet to Arus, only to have the Lions waiting to dish out a good pounding. Adding insult to injury, they didn't even form Voltron to send him away in defeat.

And the obessession over Allura begins for Lotor! He's on Doom, plotting for the first time of many a way to make her all his.

There is a fairy tale on planet Arus of star-crossed lovers who united their kingdoms when they met on a bridge between the two lands. As the Princess of Arus, Allura takes part in a ceremony where the famous meeting must be recreated. A bit of chance lands Hunk in the role of the lucky guy, but the ceremony is crashed by Lotor! Hunk and Allura are trapped on the bridge, leaving the others with no way to form Voltron.

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. They meet the high strung younger prince, Bandor, and his sister Romelle -- who bares an uncanny resemblance to Princess Allura. But the king's first son, Avok, volunteers to become a Robeast to fight Voltron. Because he is willing, the evil Haggar is able to make him the most powerful Robeast yet!

King Zarkon lies on his death-bed, and Lotor decides to use this opportunity to finish off his father and the Voltron force. Using a magic potion from Planet Doom's top alchemist, he arrives on Arus and turns the plant life against Princess Allura and her handmaidens. Keith and the Voltron Force must rescue the castle women from the monster flowers, and without the help of their Lions!

An ancient castle appears from the mists on Planet Arus. Pidge and some of the local kids go exploring, but it turns out to be Haggar's trap! The rest of the Voltron Force arrives, but they are also trapped in the castle. Haggar's Robeast begins to tow the castle to Planet Doom. The team's last hope is Keith, who manages to escape by hijacking one of Zarkon's ships. But can he defeat the forces of Doom and free the others all by himself?

Pidge's home planet of Balto is being barraged with nuclear missiles as Coran and Nanny are putting the pressure on Allura to get married. The Voltron Force (minus Allura) goes to Balto despite Coran's attempts to place them under house arrest in a last desperate attempt to save the planet.

This one starts with Princess Romelle of Pollux being tossed into a dungeon cell on Doom by Prince Lotor. Due to her resemblance to her cousin Allura, Lotor figures he might as well live vicariously through her and snag a smooch. Of course, he is seriously denied when she sends him packing with a hefty slap to the face. She even tries to stab him with a sharp rock. Poor Lotor, he gets no respect.

Seedlings flutter down from the sky to Arus, leaving beautiful and fragrant blooms. Arusians frolick in the fields of flowers and even Allura dances about with some blossoms the space mice brought her.

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.

The gist of this one is implied pretty well by the title - Zarkon and Co. send an invisible Robeast to Arus to take care of the Voltron Force. Coming back in a carriage after a day of picking fruit, Allura, Nanny, Lance and Pidge and some space mice are caught offguard when the invisible Robeast attacks. It overturns their carriage into a nearby lake - luckily, all are able to escape a watery fate. But before Allura can climb out of the lake, the Robeast picks her up and carries her away. After a few well placed laser blasts from Pidge's pistol, the Robeast drops Allura. However, it's not done with them. Hiding near a bluff, they're shocked to find a bolder the Robeast threw barreling toward them. Fortunately, the others at the Castle caught an inkling of what was going on and so the boulder harmlessly ends its journey on the back of Black Lion.

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.

This one has that amusing sequence where the Voltron Force is honing their hand-to-hand combat skills and Allura lays the smackdown on Lance. Depsite how tough she is, Allura's still no match for Nanny's and Coran's combined anal retention. In yet another instance of same-ish plot recycling, Allura is hauled off to do more Princess-worthy activities.

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!

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.

After a windstorm devastates a large city on Arus, Pidge gets into a fight with a suspected looter, Tommy. Pidge ends up making friends with Tommy, who won't evacuate the ruined city because of his bedridden mother. But when Pidge explores the earthquake zone where the woman was injured, he finds an underground tunnel, leading to the drill machine Lotor snuck onto Arus under the cover of the storm!

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.

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.

Trying to protect Planet Arus, Prince Bandor has been forced to bombard the Omega Comet with his fleet, while Voltron was still on it! The comet has been redirected, careening toward the End of the Universe with a seemingly dead Voltron still trapped on it. Violating a command from Galaxy Garrison, Bandor tries one last-ditch plan to save Voltron, and fails as Lotor's surprise attack cuts his fleet to ribbons!

Furious at his defeat, Lotor throws Princess Romelle into the Pit of Skulls, from where no one has ever returned. But she is rescued by a wild man, an escaped slave who has been living alone in the caves under Planet Doom. Shocked, she realizes the wild man is Sven, former member of the Voltron Force! Romelle must help Sven reconcile with his painful past and take up the mantle of hero once again!

Lotor sets up his command base on a desert planet, planning to enslave the peaceful Sand People and turn them into Robeasts. A local researcher, Professor Sawa, realizes what's happening and calls in the Voltron Force. Princess Allura meets with the Sand People, and sees that they are innocent and childlike. She gives one her bracelet as a present. But when Lotor attacks with his new Robeast, Allura recognizes the bracelet on the monster's arm.

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.

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.

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!

When Zarkon first ravaged Planet Arus, Coran sent his wife and young son away for their own safety. He never heard from them again. One day, Princess Allura is saved by a mysterious young man named Garrett. He appears to be a natural pilot, and the Voltron Force take him in as a new recruit. Then, Coran notices a scar on Garrett's arm and realizes he's none other than his long lost son!

Garrett betrays the Voltron Force, allowing Lotor to fly an enormous Pulsar Cannon within range of the castle. Voltron rushes to stop it, but is attacked by a Robeast. As the two giants grapple, Lotor mercilessly blasts them both! Voltron is split into five parts, each one crashing down to Arus. If the Voltron Force can't get back together by sunrise, the Pulsar Cannon will recharge and vaporize the castle!

Lotor fails to capture Planet Arus and allows the Voltron Force to capture the Pulsar Cannon. For his incompetence, King Zarkon has his son imprisoned! Princess Allura and her alliance of local planets see their chance to launch a counterattack on Planet Doom itself. They disable Planet Doom's shield with a shot from the Pulsar Cannon, only to be faced with the ultimate Robeast: King Zarkon himself!

Lotor has broken out of prison and taken over the throne of Planet Doom, as his father battles Voltron personally in the skies above! Sven and Romelle lead a team of commandos to blow up the Robeast laboratory. But Zarkon destroys the Blazing Sword, and Lotor surrounds Voltron with flying explosives, making it impossible for the team to move. The only one who can save them now is... Witch Haggar?

Lotor activates his command center, Dark Doom Castle. Even with all his might, Voltron cannot fight off the entire castle alone. The team tries to hold on just long enough for Sven and Romelle to free the slaves. At the last moment, Coran flies to the rescue with the Castle of Lions in starship mode. While the fight rages, Sven sneaks into the evil castle alone to challenge Lotor personally!
