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.

The Justice League operated from a secret cave outside of the small town of Happy Harbor, Rhode Island.

After a year of being a team (1969), 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.

Formation of the SuperFriends


In late 1971, shortly after the Martian Manhunter had left Earth, a group of the Leaguers gathered together and decide to 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 founding members of the Justice League's Superfriends organization consisted of Aquaman, Batman, Robin, Superman, Wonder Woman, Hawkman, the Flash, Green Lantern, Black Vulcan and Samurai. This is another significant departure from the parallel universe of Earth-One.

The name stuck for years, and over time, the name Superfriends was used to describe all members of the Justice League of America. It was not long before their volunteer organization expanded and they added Marvin White and Wendy Harris, to the Junior SuperFriends.

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

Known SuperFriends Members
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.

Robin and Firestorm were considered Jr. Super heroes in The Case of the Shrinking Superfriends

Headquarters
Instead of moving their headquarters into an orbiting satellite as they did in the parallel universe of Earth-One; their base of operations is the Hall of Justice, located in 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.

The JLA also make use of the Justice League Satellite, which transmits video images from space and other information to the Hall so as to allow the Leaguers to monitor outer space.

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.
