[Masters of the Universe] So...what exactly is Skeletor?

I mean...is he just a guy in a skull mask? A demon? A possessed Halloween costume? He seems to like spandex to show off his muscle tone but I haven't the foggiest what he actually LOOKS like under that getup.

Skeletor was once Keldor, brother of King Randor, and Prince Adam's uncle. He wanted the power of Greyskull for himself, and rebelled against his brother's rule. His face was disfigured by a vial of corrosive liquid during an attack on the Hall of Wisdom. Keldor was brought to Hordak, an interdimensional demon, who agreed to save Keldor's life in return for a pledge of service. He does uphold his bargain, but burns all the flesh from Keldor's face and renames him Skeletor.
