Grogg

Grogg crashes into the Modern Age with a memorable debut in Nick Fury's Howling Commandos #1 [Director's Cut] (2005), courtesy of creators Keith Giffen and Eduardo Francisco — and the company alone tells you everything about the wild, monster-mash energy of this corner of the Marvel Universe. Sharing pages with the likes of Frankenstein Monster, Vampire by Night, and Zombie, Grogg clearly inhabits a gloriously strange world where the supernatural and the super-heroic collide. With appearances also in Fantastic Four / Iron Man: Big in Japan, this is a character who pops up in some genuinely offbeat Marvel adventures worth seeking out for the curious collector.
