Real name unknown and with no other alias, The Joker loves destruction, anarchy and chaos. Donning a purple suit and painted up like a clown, he has a severely disfigured face which only enhances his menacing nature. He has no rules, and wants only one thing; to kill Batman, the masked vigilante of Gotham City. The Joker character has been played by many actors, including Jack Nicholson and Cesar Romero, but none more memorable than Heath Ledger's Joker in The Dark Knight. It's not a comical caricature like Nicholson, but it's a very dark and intensely scary character that will haunt your subconscious.
