A devil born from humanity's revulsion toward roaches, this towering creature surfaces briefly during the Justice Devil arc as an enemy of Chainsaw Man. Their clash tears across the city, costs the Bat Devil its life by accident, and ends with Denji choosing a stray cat over the crowd.

Fellow devils mean nothing to it; when its own descent crushed the Bat Devil, it never paused to notice.
