The Justice League, also called the Justice League of America or JLA, is a fictional superhero team that appears in comic books published by DC Comics. First appearing in The Brave and the Bold #28 (February/March 1960), the Justice League originally featured Superman, Batman, Wonder Woman, Flash, Green Lantern, Aquaman, and the Martian Manhunter. The team roster has been rotated throughout the years with characters such as Green Arrow, Captain Atom, Captain Marvel, Black Canary, the Atom, Hawkman, Elongated Man, Red Tornado, Firestorm, Zatanna, Hawkgirl, Cyborg, Vixen, and dozens of others. Sidekicks like Supergirl, Robin, Aquagirl, and Speedy tend to support the main hero or heroine. The team received its own comic book title in October 1960, when the first issue was published. It would continue to #261 in April 1987, which was the final issue. Throughout the years, various incarnations or subsections of the team have operated as Justice League America, Justice League Dark, Justice League Europe, Justice League International, Justice League Task Force, Justice League Elite, and Extreme Justice.

Justice League Heroes is a console video game for the Xbox, PlayStation 2, Nintendo DS, and PlayStation Portable systems. It is based on DC Comics' premiere superhero team, the Justice League of America. It was developed by Snowblind Studios and published and distributed by Warner Bros. Games for all systems except Xbox which was distributed by Eidos Interactive in conjunction with DC Comics. It is based on the long running comic book series, (as opposed to other recent Justice League games which are adaptations of other media besides the source material) and was written by veteran comic book and Justice League of America writer Dwayne McDuffie. It uses the Dark Alliance Engine. Two handheld Justice League Heroes games were released at the same time for the GBA and Nintendo DS systems. The Nintendo DS game shares a similar visual style and gameplay mechanics to the console game, but serves as a prequel to its story. This version was developed by Sensory Sweep Studios. The GBA version is titled Justice League Heroes: The Flash and focused primarily on The Flash. The game featured 2D sidescrolling action gameplay and a sidestory to the console game's plot. This version was developed by WayForward Technologies.
