The Illuminati (of Earth-616) is a covert think-tank comprised of the world's smartest super-heroes that each represent one of the major aspects of Human society. At any given time there is at least 1 representative for each of the races that occupy the planet Earth in the group, so that all viewpoints and interests can be represented. The group works behind the scences to ensure the Earth's saftey usually through tactics that most heroes would find morally questionable.
