A criminal mastermind and arguably one of the most infamous supervillains in the DC Comics universe, the Joker, the grinning killer, is the archenemy of Batman and nearly all DC Comics superheroes. He stars in comics, films, and television series, always sporting his red-painted smile to hide his damaged face underneath, wild green hair, and purple suit. Gotham City's resident psychopath, the Joker has been portrayed by various actors in television series and many Warner Bros. films over the decades.
