Editing Skeletor (section)

===Post-Filmation series minicomics===
In the 1986 minicomic "The Search for Keldor", Skeletor is implied to be Keldor, King Randor's long-lost brother, as he attempts to stop Prince Adam and Randor from searching for Keldor. According to King Randor, Keldor disappeared years ago after, in his pursuit to master magic, an experiment  went wrong and transported him to another dimension. In order to uncover what happened to Keldor, Randor and the Sorceress attempt to look through a space-time rift that opens once a year. 

However, because the original toyline ended before the story could be resolved, this has not been confirmed. [[Steven Grant]], the writer-for-hire of the minicomic, stated in a he-man.org interview that "As far as I remember, Keldor was Skeletor... But, I don't think that was ever going to be revealed... I seem to remember it as one of those things Mattel came up with out of the blue... Slur Keldor and you end up with Skeletor... His back-story wasn't really worked out. Some sort of evil cosmic energies altered him. I think they were going for a [[Darth Vader]] thing, but it was a tack-on... The main idea was that if they found out Skeletor was Keldor, they'd be able to find out what had changed him and might find some way to reverse it."<ref>{{cite web|url=http://www.he-man.org/resources/archive.php?id=28 |title=> Resources > Archives > Opening the Vault > Steven Grant - writer |publisher=He-Man.org |access-date=2011-12-29}}</ref>

In the Masters of the Universe Classics toyline, he is Randor's half-brother, whose mother was a member of the Gar race, and was ousted from the royal castle due to his Gar heritage. While roaming Eternia in search of knowledge, he learned the Dark Arts from Hordak and sought to unite Eternia by ruling it himself. After battling Randor and losing, he turned to his mentor, Hordak, to survive and was merged with an entity known as the Demo-Man, becoming Skeletor.<ref>{{cite web |url=http://www.mattycollector.com/store/matty/en_US/DisplayProductDetailsPage/productID.188412500 |title=Online Store - Keldor Figure |publisher=Mattycollector.com |date=2011-02-15 |access-date=2011-12-29 |archive-date=2012-01-15 |archive-url=https://web.archive.org/web/20120115110127/http://www.mattycollector.com/store/matty/en_US/DisplayProductDetailsPage/productID.188412500 |url-status=dead }}</ref>
