The Justice League
The Justice League first appeared in the comic book The Brave and the Bold #28 in 1960. The first members were Superman, Batman, Wonder Woman, Flash, Green Lantern, Aquaman, and the Martian Manhunter.
Over time, many other superheros have been members of the Justice League. Some examples are: Green Arrow, Atom, Hawkman, Black Canary, Captain Marvel, Plastic Man, Elongated Man, Booster Gold and Skeet and The Question. Many other superheroes joined the justice league.
Many different comic book series have featured the Justice League. The current series are Justice League of America (Volume 2) and JLA:Classified.
The Justice League has had several headquarters. These include the Hall of Justice, the Justice League Satellite, and the Justice League Watchtower.
It is rumored that there will be a 2015 action-adventure film based on The Justice League with the same name. The movie will include Batman, Superman, Green Lantern, and Wonder Woman. The movie is on-hold just because they say that if the new 2013 Superman movie Man of Steel becomes of a success then the movie will be made.
