Justice League Unlimited (2004 - 2006)

In a world of extraterrestrial invasions, powerful sorcerers, vast shadowy conspiracies and ancient gods, the galaxy's most powerful superheroes return to battle the allied villains and criminal plots that endanger the universe.

Two years ago, the world's greatest heroes banded together as the Justice League and dedicated themselves to battling threats too great for any single hero to handle. Since then, they've saved the world countless times from unimaginable dangers. But the price has been high. With their ranks diminished after fighting off an alien invasion and with new dangers arising at an ever-increasing pace, the remaining Justice League crime fighters realize that protecting the entire world is going to take more technology and manpower than they have at hand. A lot more.

These heroes come home to roost in their high-tech Watchtower, sporting space-based energy weapons and a powered-up fleet of Javelin spaceships. The team members tap innovative matter-transporters that zip them from one location to another in a flash.

Superman, Batman, Wonder Woman and Green Lantern continue to lead the universe's most powerful superheroes, including such well-known defenders as Supergirl, Green Arrow and the Atom as well as Booster Gold, Hawk & Dove, Elongated Man, Mister Miracle, Big Barda and Zatanna. These fearless fighters and many others are the Justice League Unlimited.
