Chrome

Debuting in the pages of The X-Men Annual #1 in 1992 — courtesy of the superstar creative team of Fabian Nicieza and Jim Lee, with finishes by P. Craig Russell — Chrome arrived right at the height of the X-Men's explosive Copper/Modern Age renaissance. A Marvel creation with a collector-significant key issue to their name, Chrome shares the page with luminaries like Colossus, Jubilee, and Sean Cassidy, placing them squarely in one of the most beloved corners of the Marvel Universe. Though their catalog footprint is compact, Chrome has earned enough staying power to appear across three decades and land a dedicated entry in the All-New Official Handbook of the Marvel Universe A to Z — the kind of recognition that separates a true piece of X-history from a one-panel footnote. For deep-cut X-Men enthusiasts and Copper Age completists, Chrome is exactly the sort of discovery that makes digging through annuals so rewarding.
