Inuyasha (20)
Geez, Inuyasha, didn't your mom teach you to wash your hands before dinner? He is called a hanyou--a demeaning term that really ticks him off--because he's, well, only half youkai. This is the demon half which erupts from time to time in a very unpleasant way. And he looks unpleasantly pleased about it, too! (Ok, yes, the truth is that I'm thrilled to finally have one of these!)
