Peter

Debuting in the pages of X-Men Annual #12 in 1988 — a landmark Copper Age issue crafted by the legendary team of Chris Claremont and Art Adams — Peter is a Marvel character whose origins are rooted in one of comics' most celebrated creative eras. With appearances spanning all the way to 2011, this figure has quietly persisted across decades of Marvel history, surfacing in the pages of The Uncanny X-Men and the Evolutionary War Omnibus alongside a remarkable roster that includes Colossus, Ka-Zar, and Alison Blaire. A rare find for the dedicated completist, Peter may be modest in total catalog appearances, but that debut issue alone makes them a character worth tracking down — Claremont and Art Adams together were producing some of the most sought-after comics of the age.
