Just to prove I'm not just using this to talk about my medical issues.
One of the more obscure members of my headcast, mostly because I rarely get a chance to play him, is Skeletor. Not the cartoon guy (although he had his moments), but Skeletor as portrayed by Frank Langella in the Masters of the Universe live action movie. He's a bit quite a bit more casual about his evil (along with a lot less naked, although the whole gay for He-Man thing's still there) and really seems to be enjoying himself even in the little vices, which makes him pretty fun to play.

You may find clips of Skeletor being awesome here and here, with attempts at awesome that end with him falling down an unexplained and completely random pit here.

As a bonus, you've just seen most of the best parts of Masters of the Universe (minus the bits featuring more Skeletor), so you don't actually have to watch the rest of the kind of movie which features He-Man driving a pink cadillac around a New Jersey suburb if you're not the sort of person who likes that flavor of ridiculous the way I do.
