Dirty Details Done Dirt Cheap:
The former leader of her own Brotherhood of Evil Mutants, Mystique is a frequent terrorist, assassin and all-around bad girl that's been around for so long (she's supposedly over 100 years old) and assumed so many different personalities that she no longer knows her own name and origin. She's made a name for herself in the X-Men universe through her slinky, foreboding appearance, her numerous affiliations with various villain groups and eventual turn with the X-Men. In the comics mythology, Mystique is the mother of both the villainous Graydon Creed (the result of Mystique's seduction of Victor Creed) and Kurt Wagner, aka Nightcrawler, and is the foster mother of Rogue. In any mythology, she's crazy hot.
