Fiend

A Fiend (魔人) (literally: Jinn) is a devil which has taken over a person's corpse.

Overview
Fiends can be identified as fiends due to their heads having distinct shapes, such as Power's horns, Beam's shark head or Pingtsi's hair.

Fiends have the personality of the devils which took over their corpses. However, some fiends retain more of the original corpse's brain than others, leading to their personalities becoming mingled. The only known case of this is the Violence Fiend who should be inclined towards violence but instead prefers peace.

Abilities
Fiends possess the supernatural abilities of their respective devils in a lesser degree. They can restore their health by consuming blood from humans, fiends or other demons. However, they are unable to make contracts with devils or humans either.
