The Joker is a fictional character and super villain that appears in the comic books published by DC Comics. Created by Bill Finger and Bob Kane, with contributions by artist Jerry Robinson, the Joker is the archenemy of the superhero Batman and first appeared in Batman #1 (Spring 1940). The Joker is a master criminal with a clown-like appearance, including bleached white skin, red lips, and green hair. Initially portrayed as a violent sociopath who murders people and commits crimes for his own amusement, the Joker, later in the 1940s, began to be written as a goofy trickster-thief. That characterization continued through the late 1950s and 1960s before the character became again depicted as a vicious killer.
He has been responsible for numerous tragedies in Batman's life, including the paralysis of Barbara Gordon (Batgirl/Oracle) and the murders of Jason Todd (the second Robin) and Jim Gordon's second wife Sarah Essen.
In 2006, Wizard magazine rated Joker as the greatest villain of all time.
