The Justice League, also known as the Justice League of America, is a fictional superhero team appearing in American comic books published by DC Comics. The Justice League was conceived by writer Gardner Fox, and first appeared in The Brave and the Bold #28 (Feb.-March 1960).
The team is an assemblage of superheroes who join together as the Justice League. The seven original members were Superman, Batman, Wonder Woman, Green Lantern, Martian Manhunter, Aquaman, and Flash. The team roster has rotated throughout the years, consisting of many superheroes from the DC Universe.
