Krollar

Stomping onto the scene in the Bronze Age Marvel Universe, Krollar made their debut in Godzilla #12 (1978), courtesy of the dynamic duo of Doug Moench and Herb Trimpe. With only four cataloged appearances, this is a rare and curious corner of Marvel history — the kind of deep-cut discovery that serious collectors love to unearth — sharing pages with the King of the Monsters himself alongside Marvel stalwarts like Dum Dum Dugan and Gabe Jones. The fact that Krollar's footprint extends into The Spectacular Spider-Man Weekly makes this a wonderfully eclectic Bronze Age artifact worth tracking down.
