Although the Joker is generally thought to have been destroyed for good in this movie, he is not actually completely gone, as he has a still-living counterpart in an alternate universe introduced in the "Justice League" episode, Justice League: A Better World: Part II (2003), in which the Joker has been lobotomized by that dimension's Superman and now serves as the superintendent of Arkham Asylum. However, this alternate Joker's status, by the time of the movie, is unknown.
