Database of Demons, Evil Spirits, and Monsters
Virtually all religions & cultures have various supernatural spirits that are considered malevolent or even evil.
- In ancient cultures, demons were thought to be the cause of illness, epilepsy, and other diseases.
- A chaos monster might attempt to overthrow the general order of the gods and upset the balance of the cosmos.
- Underworld and fertility deities can be vengeful if certain rites and rituals aren’t followed and may cause the next year’s harvest to be meager.
- In some cultures, demons may be forces of nature like hurricanes that can kill people and livestock and destroy villages and crops.
- And in some belief systems, they are evil spirits that can cause misfortune, destruction, illness, and death because of a chance encounter.
This page was created as a study of how different religions of the world personify “evil.” Throughout this section, you’ll find lists of demon names and descriptions of different demons, devils, monsters, and evil spirits.
Note: What is “evil” is often defined by a specific belief system. One religion’s gods become another religion’s demons – especially as Christianity became dominant and demonized pagan or foreign gods and goddesses.
What Demons and Monsters Are Included?
Below, you will find some criteria I used to decide whether to include an a demon or monster on this list:
Gods and Goddesses of the Underworld
If a god or goddess is associated with death, involved in the annual fertility rituals of the harvest, or is a caretaker of the underworld, I have included them.
God of Chaos and Destruction
Some gods and goddesses are known for having a destructive side when angered. They may kill, drink blood, or cause havoc for entertainment.
The Personification of Natural Evil
Some belief systems like the Mayans and Native Americans thought that the destructive elements of nature were gods that needed to be appeased or sacrificed to.
The trickster is a supernatural entity who is mischievous and often causes trouble. A trickster might be a god or associated with animals like Ravens and Coyotes.
