A poor man named Nepthu limps across the Sands of Time in search for the Temple of The Sun. Inside he claims the Scarab of Power, a magical jewel. The scarab's power transforms Nepthu into a muscular, dominating being. Nepthu uses the scarab to capture a falcon flying over the Sands of Time, which just happens to be Zoar. The Sorceress contacts Adam through telepathy revealing her location.
Adam immediately becomes He-Man, but Cringer refuses to become Battle Cat. When they arrive at the Temple of The Sun, many obstacles block their path, thus Cringer finally decides to become Battle Cat. Nepthu is busy creating an army of Sand Demons with which to take over the world.
Zoar tries to escape but Nepthu stops her fleeing by crystallizing her. He-Man confronts Nepthu and along with Battle Cat defeats all of his Sand Demons. He-Man takes the scarab and destroys it. Nepthu turns back into his normal self and Zoar is freed.
