raised an army of powerful minions of his own and took over as ruler of Snake Mountain. Skeletor's main goal is to conquer the mysterious fortress of Castle Grayskull, from which He-Man draws his powers. If he succeeds, Skeletor would be able to conquer not only Eternia, but the whole universe. At the same time, his other goal is to take revenge on Hordak and overthrow Horde Prime in his bid to conquer the universe. Skeletor appeared in 71 of the 130 episodes of the 1980s He-Man cartoon (33 episodes in the first season, 38 in the second) and in 9 of the 93 episodes of the spin-off She-Ra: Princess of Power, for a total of 80 appearances, and also in The Secret of the Sword and A Christmas Special. He was voiced by Alan Oppenheimer in both series. While he was occasionally seen as a bumbling figure whose plans were always foiled by He-Man and his friends, his intentions to conquer Eternia were taken seriously by He-Man, and sometimes by She-Ra. He-Man regarded Skeletor as his arch-foe, and Skeletor's plans were sometimes ruined through the fault of his minions rather than by his own incompetence.

This contradicts both earlier minicomics and cartoon series. This implication occurs specifically in the 1986 minicomic entitled "The Search for Keldor", a story that involves Prince Adam and Randor searching for Randor's lost brother Keldor. When Skeletor learns of their quest, he muses that "they must never discover the secret of Keldor", as the truth will lead to his destruction. In this story, King Randor announces that Keldor disappeared years ago. "He thought to master magic; when his experiments went wrong and he was lost in a dimension beyond time!" One of the few elements of Skeletor's back story that remains consistent throughout the various continuities is that he had come to Eternia from another dimension. It is likely that Randor's statement about Keldor disappearing to another dimension is an attempt to reconcile Skeletor being He-Man's uncle with his Extra-Eternian origins. To find out what happened to Keldor, Randor and the Sorceress attempt to peer through a space-time rift that opens once every year. Randor announces "I think I see Keldor... Or is it..." Before he can see anything else, Skeletor appears,
