The Joker is a fictional character, a comic book supervillain appearing in DC Comics publications. The character was created by Jerry Robinson, Bill Finger, and Bob Kane, and first appeared in Batman #1 (April 25, 1940). Credit for the character'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.
In his comic book appearances, the Joker is portrayed as a criminal mastermind. Introduced as a psychopath with a warped, sadistic sense of humor, the character became a goofy prankster in the late 1950s in response to regulation by the Comics Code Authority, before returning to his darker roots during the early 1970s. As Batman's nemesis, the Joker has been part of the superhero's defining stories, including the murder of Jason Todd—the second Robin and Batman's ward—and the paralysis of Batman's ally, Barbara Gordon. The Joker has had various origin stories during his over seven decades in publication. The most common story is where he falls into a tank of chemical waste which bleaches his skin white, turns his hair green and his lips bright red; the resulting disfigurement drives him insane.

One of the most iconic characters in popular culture, the Joker has been cited as one of the greatest comic book villains and fictional characters ever created. He appears in a variety of merchandise, such as clothing and collectable items, real-world structures (such as theme park attractions) and references in a number of media. The Joker has been Batman's adversary in live-action and animated incarnations, including the 1960s Batman television series (played by Cesar Romero) and in film by Jack Nicholson in 1989's Batman and Heath Ledger in 2008's The Dark Knight (earning Ledger a posthumous Academy Award for Best Supporting Actor). Mark Hamill, Brent Spiner, Michael Emerson, Richard Epcar, Troy Baker, and others have voiced the animated character.

A term used by sport tipping websites where the tipper elects a round of his/her choice to have their total points doubled for that particular round. For example, in a round of AFL there are 9 games. If a player elects a particular round to be used as their joker round and they get 5 games correct, their score will be doubled to 10.
Boxy: I can't believe I am already 5 points off the pace after round 1. I really thought that Essendon would get up over the Suns. Luckily I still have 3 joker rounds to play to stage a comeback.

Joker Bombs is a slot inside Stake that is very clearly rigged. Joker bombs will continuously screw you over time and time again but you will still feed hella money into the game. NOTE: Only playable when Nikola Jokic scores at least a 30 point triple double.
