A felonious criminal who uses funny prank weapons and convoluted themes in his schemes to unmask the Batman and get the last laugh on the Caped Crusader! The Joker was one of the Dark Knight's most frequent antagonists as the Jester of Jackanapes.

First appearing on January 26, 1966 in the Batman live action television episode, "The Joker is Wild" and was portrayed by Cesar Romero. Romero would go on to reprise his role as the Ace of Knaves as one of the more frequent campy villains of the series and in the 1966 feature film, Batman: The Movie.


The Joker is a major supervillain in the DC Comics, first appearing in Batman #1 which was published on April 25, 1940. Bill Finger, Bob Kane, and Jerry Robinson are credited as being responsible for his creation. He has been considered to be THE principal arch-nemesis to the Dark Knight for decades and the most recognizable as well as being widely considered to be one of the greatest supervillains of all time as the Clown Prince of Crime.

Like his nemesis who uses bats, the Joker employs his own symbolism revolving around clowns, comedy, playing cards and his warped and sadistic sense of humor and mad genius have made him a potent adversary for the Dark Knight Detective along with his bleached white skin, shocking green hair, and macabre death head's grin make him one of the most visually distinctive.

The Joker has been a defining part of the mythology and history of the Batman for decades ever since his appearance. For the most part, he has never had a definitive origin story.

The Joker's identity is a mystery and at times, he has claimed various different versions which are contradictory. Some indicate that he was a failed comedian forced into a life of crime; others state that he was a former Gotham hoodlum turned crime boss who hid behind a veneer of respectability and high-priced lawyers; another history indicates that he was abused by his father with a runaway mother which turned him into a life of crime; while yet another origin proclaims that he was a brilliant but sadistic genius.

The Joker admits that even he doesn't know for sure which is real and which is false but typically all of his stories involve the Batman and the Ace Chemical Plant where he was being pursued by the Dark Knight only to to fall into a vat of chemicals. The strange mixture would turn his skin chalk white, dye his hair green, and cause his facial muscles to be pulled into a fixed rictus. Some stories have indicated that the shock of his new bizarre appearance caused him to lose his mind while others suggest that the Joker is actually sane but like his archnemesis who cultivates his reputation to make criminals superstitious and fearful of him; the Joker does the same by employing bizarre and convoluted campaigns to make himself appear to be insane but is actually a carefully cultivated mask of randomness and unpredictability.

Among his more memorable heinous acts have included murdering of Jason Todd, the second Robin; paralyzing Barbara Gordon by shooting her in the spine, ending her career as Batgirl; and murdering Commissioner Gordon's second wife Sarah Essen.

The Joker has made numerous frequent appearances in various films, animated cartoons, and television series starring the Batman over the decades.
