The Parapsychological Studies Institute, or PSI, is a complex organization of villainous criminals for use with Champions and other Hero System Games. PSI, is somewhat different from the typical comic book villains. The GM should read through the entire book carefully noting how the various members of the Institution interact and what goals and ambitions motivate each one. As always, the GM should feel free to alter the information provided to create a more unique, tailored campaign.
