General Jeremy Clarke

A military man with Marvel credentials going back to 1992, General Jeremy Clarke made his debut in X-Force #10 — right at the height of the Copper Age's bold, kinetic energy — courtesy of Rob Liefeld, Fabian Nicieza, and Mark Pacella. Over a surprisingly durable run stretching all the way to 2019, he's kept some seriously notable company, sharing pages with the likes of Domino, Cannonball, and Tabitha Smith across titles like X-Force and Cable - Blood and Metal. He may clock in at a modest nine catalog appearances, but for collectors who love the gritty, action-packed corners of the Marvel universe, tracking down a character with that kind of staying power and those kinds of co-stars is exactly the sort of rewarding deep-dive that makes Bronze and Copper Age hunting so much fun.
