Zombie Devil

The Zombie Devil has a greater hatred towards humans, particularly towards devil hunters. Since devil hunters killed his own kind, the Zombie Devil seeks to kill Devil Hunters in return. He appears to be somewhat cunning, since he managed to trick the Yakuza and turn them into zombies.

The Zombie Devil takes the form of a giant floating limbless torso with multiple exposed organs including a brain from which tentacles emerge to connect him to zombies within his horde. A large human-like face emerges from the right side of the devil's torso unconnected to where its head should be. During the fight with Denji, he loses his right eye and is later cut into two halves.

As a Devil, the Zombie Devil possesses all of the standard devil abilities, such the ability to make contracts with humans for a price. Since zombies are common horror monsters in movies and pop culture, it can be assumed that he is quite powerful. The only known contract is the one with the Yakuza. In exchange for an unknown price, the Zombie Devil agreed to lend his power to the Yakuza. However since his power is to turn people into zombies, they ended up becoming zombies themselves.
