The Justice League, sometimes called the Justice League of America or JLA for short, is a fictional DC Comics superhero team.
First appearing in The Brave and the Bold #28 (1960), the League originally appeared with a line-up that included Superman, Batman, Wonder Woman, Flash, Green Lantern, Aquaman and the Martian Manhunter. However, the team roster has been rotated throughout the years with the recognizable characters Green Arrow, Atom, Hawkman, Black Canary, Captain Marvel, Plastic Man and dozens of others. Throughout the years, various incarnations or subsections of the team have also operated as Justice League America, Justice League Europe, Justice League International, Justice League Task Force, Justice League Elite, and Extreme Justice.
Various comic book series featuring the League have remained generally popular with fans since inception because, in most incarnations, its roster includes DC's most popular characters. The League concept has also been adapted into various other entertainment media, including the classic Saturday morning Super Friends animated series (1973-1986), a lesser known live action television movie, and most recently the successful animated series Justice League (2001-2004) and Justice League Unlimited (2004-2006) and an upcoming 2011 live-action film.
