Doc

Debuting in the Bronze Age classic G.I. Joe, a Real American Hero #11 (1983) under the creative hands of Larry Hama and Mike Vosburg, Doc is a quietly enduring presence in one of Marvel's most beloved action franchises — a character who has kept pace with the series across an impressive four-plus decades, from the Reagan era all the way to 2025. With four key-issue appearances to their name, Doc is no background figure; they've earned their place in the collector's conversation, sharing pages with heavy hitters like Hawk, Cobra Commander, and Lonzo R. Wilkinson across the core G.I. Joe titles that defined a generation. Forty-eight catalog appearances spread over 42 years speaks to a staying power that casual fans might overlook but dedicated readers know well — Doc is exactly the kind of character who rewards the deep-diver.
