Peregrine first appeared in Contest of Champions #1 and was created by Mark Gruenwald, Bill Mantlo, Steven Grant, John Romita Jr., and Pablo Marcos.
He is a writer by profession, but is a superhero, adventurer, and mercenary, using a falcon-like costume with artificial wings giving him the ability to fly.
He assisted the archer Hawkeye in destroying a nuclear warhead generator stolen by the Red Skull, and freeing the Sandman—another of Silver Sable's operatives — in the process.
[9] During the Secret Empire storyline, Peregrine appears as a member of the Champions of Europe alongside Ares, Captain Britain, Excalibur, Guillotine, and Outlaw.
Peregrine wears a suit of synthetic stretch fabric that incorporates an anti-gravity generator system which emits and controls anti-gravitons, enabling him to counteract gravitational attraction.
