Poison Ivy controls nature and is usually almost naked; Catwoman is a hot burglar (and occasionally romances Batman), Talia is a hot heiress of an evil empire (and in on/off relationship with Batman). Two-face is a gangster with a coin. Penguin is also an underworld operator. Scarecrow is a psychologist gone psycho. The Riddler riddles while Freeze freezes everything (ok, those two were obviously not very well thought out). And the Joker is probably the best known of them all… he’s the Moriarty to Batman’s Sherlock.
But if you aren’t a hardcore Batman fan, chances are that you haven’t heard of this ‘Bane’ that everyone is talking about. Not your fault. Off all the Dark Knight’s foes, Bane is probably the least well-known.
