The JLA (Justice League of America) goes back to the Silver Age of comics for it's inception. First shown as a team in 1960 the original members included Batman, Superman, Wonder Woman, Flash, Green Lantern, Aquaman, and Martian Manhunter. Throughout the decades a variety of other Superheroes have joined the team to right the wrongs of the world. I particularly like the JLA comics in the graphic novel format from the 1990's that Grant Morrison worked on.
