Who He Is: One of Batman's first recurring villains, having appeared before the Joker himself. Typically portrayed as a psychiatrist, he also works as a criminal mastermind, using his great intellect to perform bizarre acts of crime. Noteworthy as being one of the first villains to figure out Batman's identity (spoiler alert: Bruce Wayne). Special Powers/Skills: The man is a genius, and has mastery of psychology, biology, and chemistry. Who Should Portray Him: I dare you to look at that picture above and think of anyone but John Malkovich. Can't do it, can you?
