The Psi Corps was originally founded by the United States over growing fears of telepaths, who had in a few short years before the creation of the Psi Corps, suddenly become quite numerous. The Psi Corps was created as a regulatory body designed to capture rogue telepaths and police the telepathic activities of telepaths.

Needless to say, under the reign of certain individuals from its inception, the Psi Corps has become one of the most powerful organizations in the Earth Sphere.
