The Joker is a fictional supervillain created by Bill Finger, Bob Kane, and Jerry Robinson that first appeared in the debut issue of the comic book Batman (April 25, 1940) published by DC Comics. Credit for the Joker's creation is disputed; Kane and Robinson claimed responsibility for the Joker's 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.
