On Eternia, the first planet of creation, a demonic tyrant rises: Skeletor! With dark armies at his command, Skeletor is on the march, hell-bent on capturing Eternia's kingdoms, and its ultimate prize - Castle Grayskull, the ancient fortress of mystery said to contain the greatest power in the universe.
It's up to He-Man and his brave squad of rookie heroes to stop Skeletor and restore the peace. Both sides come armed with enchanted Power Weapons - transforming them into Masters of the Primal Powers of the Universe. It's Master vs. Dark Master, He-Man vs. Skeletor - fighting for control of Eternia, Castle Grayskull, and the fate of us all.
