Adam X

Born into the fertile creative soil of 1994 — that wild, experimental Copper/Modern Age when Marvel was throwing bold new concepts at the wall — Adam X made his debut in X-Men #39, brought to life by writer Fabian Nicieza and artist Terry Dodson. He's a Marvel character who shares his pages with some of the heaviest hitters in the mutant world: Scott Summers, Wolverine, and Hank McCoy, as well as Spider-Man himself, which speaks to the broad Marvel universe he inhabits. His appearances stretch across two decades and touch landmark publications like Marvel 75th Anniversary Celebration, marking him as a figure with genuine staying power in the collector consciousness. Rare in the catalog and steeped in that distinctly '90s Marvel energy, Adam X is exactly the kind of deep-cut discovery that makes digging through back issues so rewarding.
