Thumbelina

Thumbelina burst onto the Marvel scene in 1990's The New Mutants #87 — a landmark Copper Age debut that also introduced Cable to the world, which alone makes it one of the most collectible single issues of its era. Over a publishing span stretching more than three decades, she's carved out a distinctive corner of the Marvel mutant universe, sharing pages with the likes of Reaper, Forearm, and Sam Guthrie across titles including X-Force Epic Collection and Cable: Second Genesis. With two key-issue appearances to her name and a presence that has persisted from the early '90s all the way to 2021, Thumbelina is the kind of deep-cut character that rewards fans who love digging into the sprawling, interconnected world of Marvel's mutant comics — a true Copper Age original with real staying power.
