The character appears only briefly in the animatic, where the spaceship's computer addresses him as the "King of Space". He appears on the computer screen as an elaborately-dressed old man wielding a scepter. He states that Scrotor has kidnapped his one hundred "smoking hot" daughters for an orgy. He claims that he's the Starbarians' king and thus commands the two save them.
The rest of the animatic follows the short misadventures of Killgar and Hogstrong on planet Terrax, where Scrotor is based, but the narrator assures the audience at the end that the duo eventually went "to go do that thing... which they eventually did".
