The World Superhero Registry is a register of ordinary people who do good deeds or fight crime whilst wearing costume. Active superheroes include: Foxfire, patrols the streets of Michigan; Entomo, a crime-fighting environmentalist in Naples; and Ghost who fights crime in Salt Lake City, Utah. Inclusion in the register is generally by invitation only; if you want to submit yourself you must provide evidence of superhero activities. Find out why they do it.
