The classic Justice League of America lineup of Superman, Batman, Wonder Woman, the Flash, Green Lantern, Aquaman, and Martian Manhunter returns, but while the team members may be familiar, the stakes aren't. This is a dark new era where aliens from another world, evil masterminds, and even the old gods themselves are waiting to test the JLA's mettle. Battles will be fought, allies will be gained and lost, and the League will be pushed to its limits like never before.

In a world where superhumans live side-by-side with mortals, the people of Earth can take comfort that some of these powerful beings are on the side of good. Superman, Batman, Wonder Woman, the Flash, Green Lantern, Aquaman, and Martian Manhunter are the world's first line of defense against alien invaders and supernatural entities. Time and again the JLA has rallied to save humankind from the brink of extinction. These are the adventures that have made them living legends.
