A long time ago, in this galaxy far, far away, a group of scientists on the planet Arus created a robot named Voltron as the ultimate defense system.
But bad guy Zarkon had it out for the robot, and after being defeated several times in his futile attempts, he sent his witch Hagar to do his dirty work for him. Disguising herself as a goddess in distress, Hagar put a curse on Voltron that split him into five lion-shaped pieces and forced him into hibernation.
That's where the legend begins...
Lucky for Voltron, a band of space explorers came along sometime around the 25th century and discovered the five sleeping lions. And none too soon, as Zarkon had already established his reign over the galaxy.
Each space explorer piloted one of the lion pieces. The leader of the group was Keith, who helmed the Black Lion and directed the formation of Voltron. Lance, the pilot of the Red Lion, was the sarcastic one, never missing an opportunity for a snide remark. The Blue Lion pilot was Sven, until a near fatal injury mid-series. He was then replaced by the beautiful Princess Allura. The tough guy of the pack, Hunk, piloted the Yellow Lion, while the Green Lion, was piloted by the remarkably agile Pidge, despite his outward geekiness.
When the danger got really heavy the five lions would form the feet, legs, arms, torso, and head of Voltron. The assembled mega-robot wielded the mighty Sword of Arus in the defense of his people and planet.
A score of other characters made this galaxy a bustling one. There was Koran, the worry-wart diplomat of the Castle of Lions (Voltron's base of operations), and Allura’s dead father, Alfor, who would appear to his daughter in frequent visions.
And then there were all the evil folks! At Zarkon's side was his right-hand man, the ineffectual Yurak, and Zarkon's son Lotar, who desired only to take his father’s place as King of Planet Doom. Hagar had her own cronies, including a group of evil monsters known as Robeasts, which were about as effective as a group of Stormtroopers (Remember the Emperor's henchmen in Star Wars?).
