Wolverine, Definitely. He's fightin' his beast side inside, and he is just wild but yet,  not without honor. He's not a cry baby like many powers, and he's cool. His story make him sometimes looklike a Looser (Hell ! He has lost Jean to cyclops, lost his wife, lost pretty much anything.) but he's goes on, and e still a force to count with.
  Yeah, this guy rocks !
