Doctor Venom

Larry Hama and Mike Vosburg unleashed Doctor Venom on an unsuspecting readership in 1983's G.I. Joe, a Real American Hero #10 — a Bronze Age debut that planted this sinister figure squarely in one of Marvel's most beloved action franchises. With a name that practically drips menace, Doctor Venom has kept dangerous company across his appearances, sharing pages with iconic figures like Snake-Eyes, Scarlett, and Hawk in the pages of G.I. Joe, a Real American Hero, Tales of G.I. Joe, and beyond. His catalog footprint may be selective — 18 appearances across four decades — but that includes a collector-recognized key issue, the kind of résumé that makes completists sit up straight. For fans who love the shadowy corners of the G.I. Joe universe, Doctor Venom is exactly the kind of deep-cut villain worth tracking down.
