Demons are a race of supernatural beings that live in the Netherworld.
The time of when Demons became apparent in the world is unclear. However, they likely have existed for 500 years during the time of the Monkey King, with the most notable appearance of Demons being the arrival of the Demon Bull King.
Personalities vary from Demon to Demon, but so far, they have shown to be cruel, sadistic, vicious, and wanting domination over the entire world.
Given their existence as other worldly beings, Demons so far have shown to possess supernatural and destructive powers, raining from immense physical attributes to manipulation of energy and the elements.
