James Buchanan Barnes

A small but intriguing corner of Marvel history, this James Buchanan Barnes made his catalog debut in Deadpool #0 (1998), courtesy of writer Joe Kelly and artist Yancey Labat — squarely in the Modern Age and deep in the gloriously irreverent world of the Merc with a Mouth. With only a handful of appearances concentrated in Deadpool's early Kelly-era run, he's a rare find for completists digging through those landmark collections. Sharing pages with the likes of Blind Al, Porcupine, and Bucky himself, this version exists in one of Marvel's most wonderfully chaotic corners — a curiosity that rewards the dedicated collector who loves hunting the unexpected edges of a beloved run.
