Inquisitor

Debuting in the pages of Marvel Comics Presents #4 in 1988, Inquisitor is a Copper Age Marvel creation bearing the fingerprints of two legends — writer Chris Claremont and artist John Buscema. This is a character who entered the Marvel Universe sharing space with none other than Wolverine, alongside the likes of Vestry, Douglas Scott, and Colonel Jody Choate, which tells you something about the intense, gritty corners of Marvel storytelling they inhabit. Though their catalog footprint is compact — six appearances spanning an impressive arc from 1988 all the way to Dark Wolverine in 2009 — that kind of longevity across two decades signals a figure with staying power in Marvel's shadows. For collectors who love digging into the deeper cuts of the Claremont era, Inquisitor is exactly the kind of discovery that makes hunting through back issues so rewarding.
