Cockroach Devil

The Cockroach Devil (ゴキブリの悪魔, Gokiburi no akuma) is a devil who embodies the fear of cockroaches. He is a minor antagonist in the War Devil arc.

Appearance
The Cockroach Devil is gigantic and has a meshwork appearance of a skeletal layer on its body that covers its head but does not fully cover its exposed torso. It resembles a humanoid cockroach and has antennae on its head and across its back.

Personality
The Cockroach Devil seems to be calculating and vengeful, hoping to catch Chainsaw Man offguard by dropping a highschool teenager and a car full of elderly people in order to test Chainsaw Man's ability to be a "superhero." It shows little regard for other devils, paying no notice when it accidently killed the Bat Devil.
