Justice League Unlimited: The Complete Series collects the animated superhero series in which the Justice League expands to take on new threats. After fighting off an alien invasion, the League's ranks are smaller. The remaining heroes decide that protecting the world will take more technology and more manpower.
The original seven Leaguers are Batman, Superman, Wonder Woman, Flash, J'onn J'onzz, Green Lantern and Hawkgirl. They are joined by a wide roster of allies, including Green Arrow, Supergirl and Black Canary.
Not everyone trusts a team this large. A conspiracy against the League named Cadmus is growing. Meanwhile, Lex Luthor leads the Legion of Doom, a group of the galaxy's worst villains, in a plan to dominate the universe. Their first goal is to destroy the Justice League.
