I am just saying that unlike Killer Croc or Poison Ivy, these Batman villians have tangled with a few people other than Batman and they don't really fight him that much unlike Joker or Two Face. Firefly is a Batman villian though, i was kind of getting desperate with him. Doesn't matter though cause he was only in one episode.
