Iceman

Few characters arrive with quite the pedigree of this Iceman, whose debut in the landmark DC / Marvel #8 (1997) — crafted by the creative team of Ron Marz, Frank Neubauer, Jackson Guice, and Josef Rubinstein — dropped him into one of comics' most celebrated crossover moments of the Copper/Modern Age. With nearly three decades of publication history stretching from 1997 to 2026 and 80 catalog appearances to his name, this is a character who has clearly resonated with readers for the long haul. He keeps exceptional company throughout those pages — sharing adventures with the likes of Jean Grey, Beast, Hank McCoy, and Professor X himself — and his appearances span marquee series including X-Men, Marvel Origins, and Die furchtlosen X-Men under the Panini Deutschland banner. Five of those appearances carry key-issue status, making this a run that serious collectors will want to track down with care.
