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.

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.

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!

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.

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 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.

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.

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.
