He-Man and the Masters of the Universe (1983) - 1x41 - The Search- Followmy.tv

Zodac comes to Grayskull and tells The Sorceress that Eternia is in great danger as Skeletor is searching for the Starseed, the single most powerful object in the universe- a small chunk of cosmic matter left over from the big bang, which can turn its holder's thoughts into reality. The Sorceress summons He-Man, and together with Battle Cat and Orko, he sets off on a race to reach the Starseed before Skeletor does. But given that the Starseed is able to give anyone all the power that they want, is even He-Man strong enough to resist being corrupted by its power?
