Joker (character)

The Joker is a supervillain appearing in American comic books published by DC Comics. Created by Bill Finger, Bob Kane, and Jerry Robinson, the character first appeared in the debut issue of the comic book Batman on April 25, 1940. Credit for the Joker's creation is disputed; Kane and Robinson claimed responsibility for his design while acknowledging Finger's writing contribution. Although the Joker was planned to be killed off during his initial appearance, he was spared by editorial intervention, allowing the character to endure as the archenemy of the superhero Batman.

In the DC Universe, the Joker is portrayed as a criminal mastermind and the antithesis of Batman in personality and appearance. He was introduced as a murderous psychopath with a warped, sadistic sense of humor but became a comical prankster in the late 1950s in response to regulation by the Comics Code Authority, before returning to his darker roots during the early 1970s. The Joker has been part of defining Batman stories, including the murder of Jason Todd—the second Robin and Batman's ward—in "A Death in the Family" (1988) and the paralysis of Barbara Gordon—the first Batgirl—in The Killing Joke (1988). Unlike many comic book characters, the Joker does not have a definitive origin story, but various possible ones have been developed. The most common story involves him falling into a tank of chemical waste that bleaches his skin white, turns his hair green and lips red, and leaves him with a rictus grin; the resulting disfigurement drives him insane.

The Joker possesses no superhuman abilities, instead using his expertise in chemical engineering to develop poisonous or lethal concoctions and thematic weaponry, including razor-tipped playing cards, deadly joy buzzers, and acid-spraying lapel flowers. The Joker sometimes works with other Gotham City criminals, such as the Penguin and Two-Face, and supervillain groups like the Injustice Gang and Injustice League, but these partnerships often collapse due to the Joker's desire for unbridled chaos. A romantic interest and sidekick for the Joker, his former psychiatrist Harley Quinn, was introduced in the 1990s. Although his primary obsession is Batman, the Joker has also fought other heroes, including Superman and Wonder Woman.

One of the most recognized characters in popular culture, the Joker has been listed among the greatest comic book villains and fictional characters ever created. His likeness has appeared on merchandise such as clothing and collectible items, and he has inspired real-world structures (such as theme park attractions) and been referenced in various media. The Joker has been adapted in live-action, animated, and video game incarnations.

Bill Finger, Bob Kane, and Jerry Robinson are credited with creating the Joker, but their accounts of the character's conception differ, each providing his own version of events. Finger's, Kane's, and Robinson's versions acknowledge that Finger showed them an image of actor Conrad Veidt in character as Gwynplaine (a man whose mouth is disfigured into a perpetual grin) in the 1928 film The Man Who Laughs as an inspiration for the Joker's appearance, and Robinson produced a sketch of a joker playing card.

Robinson stated that it was his 1940 card sketch that served as the character's concept, and Finger associated that image with Veidt in the film. Kane hired the 17-year-old Robinson as an assistant in 1939, after he saw Robinson in a white jacket decorated with his own illustrations. Beginning as a letterer and background inker, Robinson quickly became primary artist for the newly created Batman comic book series. In a 1975 interview in The Amazing World of DC Comics, Robinson said he wanted a supreme arch-villain who could test Batman, not a typical crime lord or gangster designed to be easily disposed of. He wanted an exotic, enduring character as an ongoing source of conflict for Batman, designing a diabolically sinister, but clownish, villain. Robinson was intrigued by villains; he believed that some characters are made up of contradictions, leading to the Joker's sense of humor. He said that the name came first, followed by an image of a playing card from a deck he often had at hand: "I wanted somebody visually exciting. I wanted somebody that would make an indelible impression, would be bizarre, would be memorable like the Hunchback of Notre Dame or any other villains that had unique physical characters." He told Finger about his concept by telephone, later providing sketches of the character and images of what would become his Joker playing-card design. Finger thought the concept was incomplete, providing the image of Veidt with a ghastly, permanent rictus grin.

Kane countered that Robinson's sketch was produced only after Finger had already shown the Gwynplaine image to Kane, and that it was only used as a card design belonging to the Joker in his early appearances. Finger said that he was also inspired by the Steeplechase Face, an image in Steeplechase Park at Coney Island that resembled a Joker's head, which he sketched and later shared with future editorial director Carmine Infantino. In a 1994 interview with journalist Frank Lovece, Kane stated his position:

Bill Finger and I created the Joker. Bill was the writer. Jerry Robinson came to me with a playing card of the Joker. That's the way I sum it up. [The Joker] looks like Conrad Veidt – you know, the actor in The Man Who Laughs, [the 1928 movie based on the novel] by Victor Hugo. ... Bill Finger had a book with a photograph of Conrad Veidt and showed it to me and said, 'Here's the Joker.' Jerry Robinson had absolutely nothing to do with it, but he'll always say he created it till he dies. He brought in a playing card, which we used for a couple of issues for him [the Joker] to use as his playing card.
