The Justice League of America, which is literally t3h r0xx0r. Its membership fluctuates, but always includes Superman, Batman, Wonder Woman, Green Lantern, the Flash, and J'onn J'onnz (sp?). Individuals who are often members but not always include:
Hawkman, Hawkgirl, the Atom,
Green Arrow, Aquaman, and Robin.
