John Greycrow

Few characters in Marvel's X-Men corner of the universe carry as layered a history as John Greycrow, who stormed onto the scene in the landmark Uncanny X-Men #210 in 1986 — a Copper Age debut courtesy of the legendary team of Chris Claremont, John Romita Jr., and Dan Green. Over roughly four decades of publication, Greycrow has moved through some of Marvel's most compelling corners, with team affiliations spanning the Marauders, the X-Men, the Morlocks, and the Hellfire Club — a résumé that speaks to a character who defies easy categorization. He's kept genuinely electrifying company along the way, sharing pages with Wolverine, Psylocke, and Ororo Munroe across Uncanny X-Men, X-Men, and beyond, racking up 81 catalog appearances and four key collector issues that mark real turning points in his journey. If you're a fan who loves morally complex figures with deep X-Men roots and a story still actively being written into 2026, John Greycrow is absolutely worth your attention.
