Hero: Eh, heroes are boring. Only one I'd really want to be is Bobbery. Just cuz he resembles a bob-omb version of Elite Four's Drake. Plus, he's better then Bombette.
Villain: Vega from the Street Fighter series. The fact that he's spanish is awesome enough, but he trained in martial arts and fought bulls at the same time. Though I'd prefer to have his red hair rather than his new blond look.
Gender-Bending: Myrrh from Fire Emblem The Sacred Stones. She's got the appearance of a little girl so no one suspects her of being a century old dragon capable of completely destroying her opponents and never gets hurt. How great is that?
