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!

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.

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

Keith and the team uncover the key to the Black Lion, just as King Zarkon's Robeast is about to rain havoc on Planet Arus.

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

Yurak's attack fleet is soundly defeated by Voltron. Hagar comes up with an evil plan to get Voltron out of King Zarkon's hair for good.

After watching Keith and his team 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 her out of trouble.

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.

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.

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

When Yurak takes a village of Allura's people captive, the Voltron Force is forced to surrender.

Escaping from Planet Nemon, Jai seeks out Princes Allura and the Voltron Force to help save his home. Nemon is under the thumb of Tabor, a nephew of King Zarkon.

Princess Allura's aunt Orla comes to visit her at the Castle of Lions. Allura's loyal space mice seem to hate Orla, but maybe they sense something about her that the other's can't.

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.

Princess Allura puts the whole team in jeopardy when she tries to pilot the Black Lion without permission.

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.

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.

King Zarkon lies on his death-bed, and Lotor decides to use this opportunity to finish off his father and the Voltron force.

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 Voltron Force is ready to jump into action when Pidge's home planet of Balto is under attack. However, the planet is very far, and if the team leaves, Arus would be completely defenseless.

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.

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.
