U.S. Agent

U.S. Agent is a fictional comic book superhero appearing in books published by Marvel Comics, usually those starring Captain America and the Avengers. He was created by Mark Gruenwald and Paul Neary and first appeared in Captain America #323 (November 1986) as Super-Patriot. He was later redesigned as a new incarnation of Captain America and, just a few years later, as U.S. Agent.
