Justice League of America



In the Earth-1A universe, a similar universe to Earth-One, there is a team of the greatest superhero's located on Earth called the Justice League (JL or JLA). Together they protect the Interplanetary Federation as well as the entire universe.

The League was founded in order to accomplish this goal:

To fight injustice, to right that which is wrong, and to serve all mankind.

Formation of the Justice League of America
Much of the back-story concerning the formation of the Justice League of America is the same as in the parallel universe of Earth-One; with the exception of the date of formation. Instead of the date being 1960, it was late 1968.

Originally, these heroes operated solely within their own respective territories. With the exception of their super-powered adversaries, they rarely interacted with other heroes.

The initial Justice League lineup was also the same as the Earth-One universe. It included seven of the Leagues most prominent members: Aquaman, Flash, Green Lantern, Martian Manhunter, Wonder Woman, Superman and Batman. Over the next two years Hawkman, Green Arrow, Zatanna, the Atom, Black Canary and several others were added to the roster.

At that time, the Justice League operated from a secret cave, located outside of the small town of Happy Harbor, Rhode Island.

Within a few years of being a team, the JLA entered a volunteering program to help train young people to become superheroes. Teenager Snapper Carr was the first teenage member or more specifically he was the first Junior Justice League Member.

In 1971, the Martian Manhunter had left Earth when Mars became desolate to help his people search for a new world.

The Expansion
In late 1971, shortly after the Martian Manhunter had left Earth, The Justice League enters a program to help expand the Justice League and they call themselves Superfriends. -- because (as Superman stated), "the best way for us to combat crime and be prepared for world-wide emergencies is to work together. From now on, we'll be the SuperFriends." The heroes on hand during this incident were Aquaman, Batman, Robin, Superman, Wonder Woman, Hawkman, the Flash, Green Lantern, Black Vulcan and Samurai.

The team continued to expand, as the Justice League begin to train younger members. Marvin White and Wendy Harris, and later Zan and Jayna of the Wonder Twins are the first of the trainees. This is another significant departure from the parallel universe of Earth-One.

In 1985, they changed their name again and went by the name "The Super Powers Team."

Junior SuperFriends Members
The Junior SuperFriends were young heroes that the other older heroes that were considered full time members would train to be superheroes.

Although Robin is seen training the Wonder Twins on occasion, he is still considered a junior member.

Headquarters
Initially their headquarters was the Secret Sanctuary located in the caverns of Mount Justice in Happy Harbor, Rhode Island. Eventually, with the help of billionaire Bruce Wayne, they were able to establish a suitable headquarters.

The Justice League eventually moved into a satellite above the Earth.

The Justice League also made use of an earth-base, the Hall of Justice, located in Gotham City, but later relocated to Metropolis. The Hall was equipped with an advanced communications network and "Trouble Alert" system. They maintained a relationship with important government officials such as Colonel Wilcox, who often alerted the Super Friends to various global threats, including alien invasions. At first, the Hall was not their primary headquarters, and it only served as a place to train young men and women learning to be superheroes. And the Justice League Satellite continued on as the League's official headquarters. Over time though, the Hall becomes their main headquarters.

Gathered together from the cosmic reaches of the universe – here in this great Hall of Justice - are the most powerful forces of good ever assembled.
