Demons are a species of evil magical beings, most of which are born and reside within the the Underworld. Demons primarily exist to fight the forces of good, harm and kill innocents and spread evil throughout the world.
In the hierarchy of evil, most demons serve the leader of the Underworld, the Source of All Evil. However, most demons know no true loyalty and will seek to claim power for themselves. Because of this, various sub-species of demons are often involved in internal struggles for power and territory.
Demons do not possess souls and therefore cannot truly experience and handle emotions. However, demons at least feel negative emotions such as anger and hate. While nearly all demons are inherently evil, a few have been able to overcome their nature and desire to be good.
Lower-level demons are demons that do not rank high in the demonic hierarchy. They often possess limited and common powers. Most low-level demons are under command of upper-level demons or operate in groups of tribes. However, some low-level demons possess unique powers and operate individually. It is possible for a low-level demon to rise in power by collecting powers or being granted a higher position by another demons.
Upper-level demons are demons that rank high in the demonic hierarchy. They possess more and stronger powers. Upper-level demons are often leaders in the Underworld and command lower-level demons and other evil beings. Most upper-level demons are loyal to the hierarchy, but some operate independently and only seek to fulfill their own needs and desires.
Becoming a DemonEdit
There are several ways how mortals and other magical beings can become demons.
Several species of demons, such as Vampires and the Furies, can infect other beings to turn them into demons. These infections are often sealed when the newly turned being causes harm or kills an innocent. Furies can infect witches with unexpressed anger and the transformation is completed when the witches make their first kill. However, if the anger is expressed before that, the transformation will be undone. Vampires can infect other beings with a bite, and the transformation will be complete upon the first taste of human blood. This transformation can be undone if the Queen is vanquished before this happens.
There are two types of demonic conversion. A mortal can become a demon by entering a demonic training program. This program is designed to surpress their humanity. Those in the program will earn chevrons with each step they take. The sixth and last chevron is earned upon killing an innocent, at which point the conversion is complete. However, it was shown that the soul is not fully destroyed in this process, but merely surpressed.
The second form of conversion is limited to half-demons who seek to become fully demonic. A half-demon can become a pure demon by killing all their living mortal relatives. They will earn new powers with each kill and may undergo physical changes as well.
Demonic Children are the purely demonic offspring of upper-level demons. These demons look like mortal children, but are pure evil and possess powerful demonic powers. These children often roam the mortal world to create chaos and harm innocents as they grow older. However, they can be trapped by the Ice Cream Truck, which houses a pocket dimension where the Nothing can destroy them.
Some upper-level demons infiltrate the mortal world with the sole purpose of giving birth to a hybrid. This allows demons to take a foothold in the mortal world by placing these hybrids in positions of power. Other demons, such as Manticores, breed with mortals to allow their children to blend into the mortal world. Demonic hybrids possess a soul, meaning they can reject evil and choose to become good.
