Skeletor, bony arch-nemesis of He-Man, embracing the omnipotent Ilearth Stone, has stormed Castle Greyskull, captured the Sorceress and now is busily assembling an army of clones to consummate his despicable scheme to become Lord of all Eternia. To thwart his lordliness, He-Man must first free Orko from necromantic imprisonment, enabling him to conjure a spell that will transform the prince's Sword of Power into the notorious, almighty Atom Smasher. Demolish the Ilearth Stone and Skeletor is as vulnerable as a gift wrapped stack of bones wandering through a hound pound.
