5. Wario, Wario series

Mario was too nice to make this list, but his bloated Bizarro counterpart Wario fits the bill perfectly. Created as a way for Nintendo to continue creating Mario universe games without relying solely on their flagship mascot, Wario is more spastic and rascally, always scheming for ways to snag some more dough. Oh, and farting. That dude is always farting. Wario, why you so nasty?
