Peepers

A small but genuine piece of the Modern Age Marvel mutant tapestry, Peepers made their debut in X-Men #179 in 2006 under the creative hands of Peter Milligan and Salvador Larroca — landing right in the thick of a rich, complex era for Marvel's merry mutants. With appearances stretching across nearly two decades and pages shared with heavy-hitters like Colossus, Rogue, Logan, and Raven Darkhölme, this character moves in serious company. Popping up across X-Men, Marauders, and the Wolverine Epic Collection, Peepers may be a rarity in the catalog, but for the dedicated completist, that scarcity only adds to the appeal.
