Iron Man

Few characters in the catalog boast the sheer staying power of this Iron Man — a Silver Age stalwart whose journey through comics stretches across an extraordinary 56 years, from a 1970 debut in Strange #1 courtesy of Stan Lee and Bill Everett all the way to 2026. Published under Editions Lug and appearing most prominently across Strange, Titans, and Spécial Strange, this armored icon has racked up 376 catalog appearances, no fewer than 27 of them recognized as collector-significant key issues — a testament to just how much this character matters on the page. Along the way, Iron Man shares adventures with some of Marvel's heaviest hitters: Peter Parker, Captain America, Spider-Man, Steve Rogers, and Daredevil all keep him company, placing him squarely at the heart of an interconnected heroic universe. Whether you're a seasoned collector or just discovering these classic runs, a character this enduring and this well-connected is absolutely worth chasing down.
