Magma

Emerging from Marvel's fertile Bronze Age in 1981, Magma made their debut in the pages of Marvel Team-Up #110, brought to life by the creative team of Herb Trimpe, David Michelinie, and Mike Esposito. A compact but collector-notable presence — two of their four catalogued appearances carry key-issue status — this character moves through some of Marvel's most action-packed corners, sharing pages with the likes of Iron Man and the power players orbiting Stark Industries, including Obadiah Stane himself. Showing up across Iron Man, Marvel Team-Up, and Quasar, Magma is a lean, intriguing figure from an era when Marvel's universe felt genuinely dangerous and unpredictable — a rare find for the dedicated Bronze Age hunter.
