The Joker is a comic book supervillain appearing in publications by DC Comics. The character was created by Jerry Robinson, Bill Finger and Bob Kane, and first appeared in Batman #1 (Spring 1940). As the archenemy of the superhero Batman, the Joker has subsequently appeared in television programs, films, games, and on a variety of merchandise. Throughout his comic book appearances, the Joker is portrayed as a highly intelligent, master criminal. Throughout the Joker's long history, there have been several different origin tales, but the most common has falling into a tank of chemical waste, which bleaches his skin white and turns his hair green and his lips bright red. He has been repeatedly analyzed by critics as the perfect adversary for Batman; their long, dynamic relationship often parallels the concept of yin and yang.
