Doc Samson

A brilliant psychiatrist working with S.H.I.E.L.D., Dr. Leonard Samson exposed himself to a measured dose of gamma-irradiated blood drawn from Bruce Banner, gaining superhuman strength and durability — with his power level reflected in the length of his distinctive green hair.

Few characters in Marvel's Bronze Age arrived with quite the gravitational pull of Doc Samson, who crashed onto the scene in The Incredible Hulk #193 in 1975, courtesy of John Romita. Over the course of roughly fifty years — a span that speaks to genuine staying power — he's logged 215 catalog appearances, racking up ten key issues that any serious collector will want on their radar. His world revolves around the thunderous green chaos of the Hulk's corner of the Marvel Universe, where he keeps company with Bruce Banner, Iron Man, and Tony Stark, making him a fixture in stories where brains and brawn collide in spectacular fashion. If you've been sleeping on Doc Samson, half a century of Incredible Hulk adventures is more than enough reason to wake up.
