(Left to Right) Aquaman, Martain Manhunter, Wonder Woman, Zatanna, Superman, Flash II, Green Lantern II, Green Arrow and Black Canary II
These heroes are the mightiest champions of the DC universe. What banned these hero together?Silver Age
A evil, starfish-shaped alien called Starro the Conqueror (that could create mini-mind-controlling clones of himself) wanted to conquer the world! So Aquaman, the Flash II (Barry Allen), Batman, Superman, Wonder Woman, the Green Lantern II (Hal Jordon) and Martian Manhunter joined forces and stopped Starro. They decided to become a team, because they defeated Starro so well. Eventually, Green Arrow, Atom II and Hawkman joined. Their base was a hidden cave at Happy Habor, Rhode Island. Snapper Carr was their "boy sidekick", but the Joker trick him into revealing were the JLA base was, causing a resignation where Wonder Woman and Martain Manhunter left the team.
After the "Snapper incident", the JLA got a satellite base. Black Canary II, Phantom Stranger, Elongated Man, Red Tornado II, Hawkwoman, Zatanna and Firestorm all joined. Wonder Woman returned. However this incarnation was short-lived.
An extremely short-lived version of the team was based on Detroit and were called the "Justice League of Detroit". Members were Aquaman, Zatanna, Martain Manhunter and Elongated Man. However, Vixen, Gypsy, Steel and Vibe were unofficial members.
This international Justice League's member was mostly "lesser known" characters. The ranks were Batman, Black Canary II, Blue Beetle II, Captain Marvel, Doctor Light (female Japanese version), Doctor Fate, Martian Manhunter, Mister Miracle and Green Lantern III (Guy Gardner). Later former Global Guardian members Fire and Ice; Captain Atom; Booster Gold; and two Rocket Reds (Dimitri Pushkin and a robot Manhunter in disguise) joined. This team was much more humorous than previous incarnations. The team split into the Justice League of America and Europe.
Another, JLA team was formed. Members were all of the original members (see: Silver Age) and they were based on the moon. This version of the team only dealt with world crisiss and not minor crime like petty crooks (such as Captain Cold and Rainbow Raider).
During the events of 52, Firestorm formed his own version of the team that included himself, Ambush Bug, Bulleteer and Super-Chief.Modern
Superman, Batman and Wonder Woman created the newest version of the team with Green Lantern II, Black Canary II, Red Arrow (formerly Speedy), Red Tornado II, Vixen, Black Lightning and Hawkgirl.
