He-Man and The Masters of the Universe Series 2002 - Episode 01 "The Bigening"
In the past, Eternia is attacked by the sorcerer Keldor and his Evil Warriors, battling against Captain Randor and the Masters of the Universe. The Elders of Eternia, aware of this attack, seal away their magical power into an orb and prophecise that a hero will rise to defend Eternia from evil in the future, before Randor defeats Keldor by deflecting a vial of acid poison into his face. Years later, King Randor and Queen Marlena celebrate the 16th birthday of their son, the spoiled and irresponsible Prince Adam. During the party, Adam is taken by Man-At-Arms to see The Sorceress of Castle Grayskull, who explains to him that the Elders hid their power within Castle Grayskull, and the destiny of He-Man to defend Eternia from evil. Adam humbly remarks that they have made a good selection for He-Man: Man-at-Arms. When the Sorceress explains that Adam was chosen, however, he blows her off and heads back to the palace. At the same time, Keldor and his Evil Warriors succeed in disrupting the Mystic Wall that has imprisoned them on the Dark Hemisphere of Eternia, learning of the Elder's disappearance and launching an attack on the palace soon after. Adam attempts to join the fight, but after witnessing Keldor—now disfigured and referring to himself as Skeletor—kidnap King Randor, he flees back to Castle Grayskull, followed by his pet tiger Cringer and Orko, the royal magician. Using the Sword of Power, Adam transforms himself into He-Man, and then transforms Cringer into Battle Cat, being advised by the Sorceress to never reveal his identity. With his newfound power, He-Man helps the Masters fend off the Evil Warriors before saving his father from Skeletor. At the palace, Adam concedes with the Sorceress' warning not to reveal his identity; while, on Snake Mountain, Skeletor begins to plot to destroy He-Man in order to secure rule of Eternia for himself.
