Durgan

Few characters can claim a debut alongside the likes of Logan, Ororo Munroe, and Colossus, but Durgan made exactly that entrance when Al Milgrom introduced him in Marvel Fanfare #33 in 1987 — right in the thick of the Copper Age, when Marvel's mutant titles were at the height of their cultural dominance. With appearances stretching across nearly four decades and a presence in Quasar as well as the prestige pages of Marvel Masterworks: The Uncanny X-Men, Durgan occupies a quietly fascinating corner of the Marvel universe. He may be a rare find in the catalog with only a handful of recorded appearances, but that scarcity is precisely what makes him a gem worth tracking down for the dedicated Marvel completist.
