Colonel John D. Armbruster

A military man carved from the Bronze Age Marvel universe, Colonel John D. Armbruster made his debut in The Incredible Hulk #172 in 1974 — a creation of the formidable team of Tony Isabella, Steve Englehart, and Herb Trimpe. The company he keeps is extraordinary: his pages are shared with the Hulk, Bruce Banner, General "Thunderbolt" Ross, and none other than Logan himself, placing him squarely in some of Marvel's most charged, testosterone-fueled corners. Rare in the catalog but persistent across an impressive 35-year span, this is a character whose modest appearance count belies real staying power — and with a key issue among his credits, collectors have reason to take notice.
