Joker

The Joker is a supervillain from DC Comics who first appeared in Batman #1 in 1940 and was created by Bill Finger, Bob Kane, and Jerry Robinson, though credit for his creation is disputed. Originally intended to be killed off, editorial intervention preserved the character, making him Batman’s enduring archenemy. Known for his sadistic humor and chaotic nature, the Joker has evolved from a murderous psychopath to a comical prankster in the 1950s, before returning to a darker tone in the 1970s. He lacks superpowers but uses chemical weapons and themed gadgets, and is often associated with other villains and his sidekick Harley Quinn. Widely regarded as one of the greatest comic book villains, the Joker has become a cultural icon featured in merchandise, media adaptations, and theme park attractions.
