It was hinted that Skeletor might have once been Keldor, the brother of He-Man's father, King Randor.

Early Skeletor

Skeletor as he appeared in the early Minicomics.

Skeletor was originally an inhabitant of another dimension, populated with others of his kind. During "the great wars", a dimensional hole opened up and Skeletor was thrown from his home dimension to Eternia. Skeletor initially sought to open a portal back to his homeworld, which would allow his people to invade and conquer Eternia alongside him, before he became more interested in simply seizing the power of Castle Grayskull for himself.

In later Minicomics, which largely ignored Skeletor's original origin and took more cues from the animated series, Skeletor was hinted to be the long lost brother of King Randor, Keldor, who was said to have disappeared many years ago when he was lost in another dimension. Skeletor was determined that no one should learn the secret of Keldor, as the truth would lead to his destruction. Skeletor was also forced to contend with the return of his old mentor, Hordak, and forged an uneasy alliance with King Hiss.
