Grottu

Grottu is one of Marvel's classic monster-era throwbacks, brought into the modern spotlight in 1998 by Roger Stern and Mike Manley. Emerging in the late Copper/Modern Age, this creature shares the page with a wonderfully wild roster — Taboo, Gargantus, Rommbu, and even Giant-Man — the kind of company that signals Marvel's deep love for its pre-superhero monster mythology. Grottu's appearances span titles like Marvel Monsters: Devil Dinosaur and Nick Fury's Howling Commandos, a gloriously eclectic mix that speaks to the character's cult appeal across corners of the Marvel Universe. Rare in the catalog with just three appearances, Grottu is a collector's gem for fans who relish the strange, oversized creatures lurking in Marvel's rich and wonderfully weird history.
