Galen Kor

A Copper Age menace who made his Marvel debut in The Avengers #366 in 1993, Galen Kor is the kind of antagonist who earns his place by sharing panels with heavy hitters like Captain America, Thor Odinson, and Warbird. Created by Glenn Herdling and Mike Gustovich, he cuts a striking figure in the early Modern Age, appearing across Avengers and Iron Man titles through the mid-to-late nineties. His catalog footprint may be compact, but any character who goes toe-to-toe with Earth's mightiest makes a lasting impression worth tracking down.
