Colossus

Few characters carry the weight of nearly half a century of Marvel storytelling quite like this Colossus, who made a Bronze Age entrance in Howard the Duck #9 in 1981 under the hand of creator Lynn Graeme. A proud member of the X-Men, this is a figure who has kept remarkable company across the decades — sharing pages with Wolverine, Storm, and Scott Summers in the storied pages of The Uncanny X-Men and the more recent Immortal X-Men. With at least one key collector issue to their name and a publishing history stretching all the way to 2026, Colossus has proven to be a genuinely enduring presence in the Marvel universe. If you love the rich, interconnected world of mutantkind, this is a character whose appearances are well worth tracking down.
