I would probably say Tom or Cassius from Kimba the White Lion. Or perhaps one of the Black Four (From Kimba the White Lion), most likely the one whose eyes turn up instead of down, giving him a goofy look rather than a sinister one. Also, Cheetah (from Kimba the White Lion) is pretty cute.
Gosh, I'm falling in love with all of the bad guys. XD (Except Cheetah, he's not a bad guy.)
EDIT:I have a huge crush on Cassius now, bigger than I have anybody else I mentioned. <3
