DC Universe: Justice League Unlimited When the villain Starro attacked Earth, it took the combined efforts of Aquaman, Green Lantern, Flash, Wonder Woman and Martian Manhunter to defeat him. As a precautionary measure against future large-scale threats, the group formed a team known as the Justice League to protect the Earth. Later Superman and Batman joined the team and have since expanded their roster.
The Justice League operated from a secret cave outside of the small town of Happy Harbor, Rhode Island. Since then they've had several base of operations including the Justice League Satellite and the Hall of Justice. Currently the team operates out of the JLA Watchtower.
