Kosmos
Kosmos is a Marvel cosmic entity — the combined essence of the Beyonder and Molecule Man merged into a single new being of immense cosmic power, taking form at the conclusion of a reality-altering crisis.
Born in the pages of Fantastic Four Annual #23 in 1990, Kosmos is a Marvel cosmic entity whose debut — co-created by Len Kaminski and Greg Capullo — landed at the intersection of the Copper and Modern Ages, when Marvel was pushing its universe to its grandest, most ambitious scales. With only a handful of catalogued appearances across a surprisingly long 21-year publishing span, Kosmos is a rare, enigmatic presence — the kind of figure who drifts through the Marvel cosmos like a rumor, surfacing in the company of powerhouses like The Thing and the Human Torch before turning up in the world of the Thunderbolts. That one key-issue appearance makes this a character worth hunting for collectors who love the deep end of Marvel's cosmic mythology.
