Adam 3,031

A Bronze Age curiosity born in the pages of Amazing Adventures in 1975, Adam 3,031 emerged from the imaginative collaboration of Don McGregor and Craig Russell — a pairing that brought genuine artistic ambition to Marvel's more experimental corners. Though appearances in the catalog are rare, this character shares the page with some compelling company: Killraven, M'Shulla Scott, and the evocatively named Eve 3,031, suggesting a world richly populated with striking figures. The fact that Adam 3,031 surfaces again as late as 2017 — across a span of some 42 years — hints at a staying power that transcends a modest page count. For collectors drawn to the wilder, more literary edges of Bronze Age Marvel, that debut issue alone makes this a name worth tracking down.
