Keldor is a character in several versions of the Masters of the Universe franchise. In the 1980s he is only briefly mentioned as being the long-lost brother of King Randor, and in the 2002 animated series he is depicted as Randor's rival who becomes disfigured and becomes Skeletor. It has been generally accepted that these two characters are in fact the same man, although this was never directly stated in any canon until the Masters of the Universe Classics line. As a result of Keldor's introduction to the mythos, Skeletor is unwittingly the uncle of his archnemesis He-Man.
