The Justice League is a fictional superhero team appearing in American comic books published by DC Comics. The team was conceived by writer Gardner Fox and first appeared in The Brave and the Bold #28 in 1960. The original lineup brought together DC's most popular heroes—Superman, Batman, Wonder Woman, The Flash, Green Lantern, Aquaman, and Martian Manhunter—into a single ongoing series, establishing the shared universe concept that would define DC Comics for decades.
The Justice League's formation marked a pivotal moment in comic book history, reviving the superhero genre during the Silver Age of Comics. The team operated from the Hall of Justice and later the Watchtower satellite, facing threats too large for any single hero. Over the years, the roster expanded to include dozens of heroes, with various iterations and spin-off teams like Justice League International, Justice League Dark, and Justice League Elite.
The Legion of Doom, introduced in the 1970s Super Friends animated series and later incorporated into comics, became the Justice League's iconic counterpart—a coalition of supervillains led by Lex Luthor. This villainous alliance typically includes major antagonists like Sinestro, Black Manta, Cheetah, Gorilla Grodd, and others, united by their shared goal of defeating the Justice League. The dynamic between these two teams has become one of the most enduring rivalries in superhero fiction.
