Grom

A card-carrying member of the Fantastic Four's extended world, Grom stepped onto the Marvel stage in 1971 — right in the thick of the Bronze Age — debuting in the pages of Fantastic Four #113, a key-issue entry point into a corner of Marvel history worth exploring. With a catalog presence stretching across four decades and appearances in Fantastic Four, Marvel's Greatest Comics, and Quasar, this character has quietly woven themselves through some of Marvel's most beloved corners. Grom keeps remarkable company, sharing pages with the likes of The Thing, the Human Torch, and Susan Storm Richards — the very heart of Marvel's First Family. Twenty-four appearances across forty years may sound modest, but for dedicated collectors, that kind of long-tail presence in flagship titles is exactly the kind of thread worth pulling.
