Nemesis

Stepping out of the cosmic shadows in Jim Starlin and Ron Lim's The Thanos Quest #2 (1990), Nemesis is a Marvel character born at the intersection of the Copper and Modern Ages, when cosmic storytelling was reaching some of its most ambitious heights. With a debut appearance in one of Marvel's most celebrated cosmic sagas — and pages shared with universe-shaking figures like Thanos, The Grandmaster, and The Collector — this character keeps genuinely rarefied company. Rare in the catalog with only a handful of recorded appearances, Nemesis carries the mystique of a deep-cut cosmic entity, the kind of find that rewards fans who love to dig beneath the surface of Marvel's vast universe.
