Gronk

Gronk is a Bronze Age Marvel curiosity who first lumbered onto the scene in 1981's Marvel Two-in-One #71, conjured up by the talented team of Mark Gruenwald, Ralph Macchio, Ron Wilson, and Gene Day. Over a surprisingly long publishing footprint stretching nearly three decades to 2010, this minor but persistent figure pops up across titles like Quasar and Marvel Two-in-One, sharing pages with heavy-hitters like Iron Man and memorable villains such as Maelstrom and Deathurge. With only a handful of catalogued appearances, Gronk is the kind of deep-cut Marvel character that rewards the dedicated completist — a small but genuine thread woven into the larger Bronze Age tapestry.
