By the Power of Grayskull… I have the Power!

A mysterious toxic gas is spreading across Eternia, ravaging farmlands and endangering citizens. The planet’s only hope lies with Adam, a lost prince with cosmic abilities. When he wields the mystical Sword of Power, he transforms from a scrawny teen into He-Man, the most powerful man in the universe.

With his friends Teela, Cringer, Duncan, and Krass by his side, Adam embarks on a dangerous journey, facing pirates, dragons, and perils at every turn in search of Moss Man, a legendary figure who might hold the key to stopping the devastating stench. Yet the sinister Skeletor and his Dark Masters will stop at nothing to thwart the unlikely heroes. The fate of all Eternia rests with He-Man and his friends.
