I am Adam prince of Eternia and defender of the secrets of Castle Greyskull. This is Cringer my fearless friend. Fabulous secret powers were revealed to me the day I held aloft my magic sword and said: "By the Power of Greyskull. I have the power!" Cringer became the mighty Battlecat and I became He-Man the most powerful man in the universe.
Only 3 others share this secret, my friends the Sorceres, Man-At-Arms, and Orko. Together we defend Castle Greyskull from the evil forces of Skeletor.
