Real Name of the Joker
The Joker is a fictional supervillain known primarily as Batman's greatest enemy. In most comic book continuities, his real name is not definitively established, and he is simply called the Joker.
In the 2019 film Joker, the character is portrayed as Arthur Fleck, a failed comedian who transforms into the Joker. This version presents a specific civilian identity for the iconic villain.
Other major interpretations include Jack Napier, the name given to the Joker in Tim Burton's Batman (1989). In the television series Gotham, the character is shown as a man named Jerome Valeska before fully becoming the Joker.
