Demons are generally malevolent entities that inhabit the dimension of Hell. They consist of fallen angels and Hellions, by birth, or by creation, such as a mortal soul so evil it is accepted as a fiend after its requisite torment. Other dark entities that are not from the Inferno may also be called demons, such as djinn, malicious deities, or supernatural creatures like Trigon.

Rhyming Caste: High raking demons by promotion. They have earned the privilege to speak in rhyme as a status symbol.
Demon Lords: There are thousands of demon lords holding land across Hell. Much like angels and saints have specific roles, certain demon lords preside over various areas. There is even a demon for every town and city around the world who grow more powerful with the populations sin, such as the Gothodaemon.

Others: Some malevolent beings have the attributes of demons without coming from Hell, but are, or could be still considered demons.
- Demons Three
- Rakkar the Nothing (Kryptonian demon)
- Mordecai Cull (Atlantean demon)
- Abyssal Dark (Atlantean demon)
- Arion (Atlantean demon)

- Creepers: Entities same as the one who possessed Jack Ryder.
- Reptawks: Flying creatures whose stings cause paralysis then death.
- Shamblers: Small demons of which little is known. Etrigan encountered one in a dream only, so they may not exist.
- Stone Giants: When wandering Hell, Jason Blood encountered a trio of towering stone demons with wings. Though little is known about them, two of the giants smelled Blood's connection to Etrigan and left him alone out of fear.

Powers and Abilities
- Demon Physiology
- Immortality: Demons are not mortal beings and do not age or die naturally. They can be destroyed, sending them to oblivion where they cease to exist. Lower class demons are easier to destroy than the powerful demon ruling class.
- Enhanced Senses: Demons have a sixth sense of sorts, allowing them to sense intangible concepts on a tangible level. Etrigan could sense evil and the supernatural, for example. Asteroth proclaimed that demons can taste fear which resembles, "peaches covered with fresh bone marrow".
- Possession: Many demons are able to possess mortal forms and control the hosts to various degrees.
- Magic: Medium to upper demon castes can use magic. They use souls as fuel for spells.
Almost all demons share the same vulnerabilities with few exceptions. Of course the higher (lower) a demon's class, the more powerful they are, generally speaking.
- Vulnerability to Theology: Theological weapons that represent the divine can ward off and harm demons, such as:
- Magic: Those with the requisite occult knowledge can summon, control, imprison, or banish demons.
- Summoning: Demons can be conjured by those with occult knowledge, and controlled if the summoner is powerful enough.
- Vulnerability to Cold: Eldritch cold can harm demons. Etrigan's life-force was once snuffed out by the frost created by the Philosopher's Stone. He also commented on how the natural cold made his blood run "sluggishly", though this may just be poetic licence.
- Lesser demons aren't even immune to Hellfire, but elite demons like Belial are hard to destroy; even with his heart ripped out he lived, but it dramatically reduced his power. The demon lord Morax was killed by decapitation. Whether or not it was the just beheading, or the fact it was a divine weapon that cleaved his neck is unknown.
- Vulnerability to Iron: Iron has long held mystical properties and harms demons on contact.
Type of Government:
- Autocratic Kingdom
- Satanic Triumvirate (Formerly)
Level of Technology:
- The majority of depictions shows demons retaining a medieval technological level, however Reign in Hell depicted a technologically advanced Hell, with demons using futuristic armour, weaponry, and computers.
- This character is an adaptation of Demon, a character in traditional stories. These include, but may not be limited to religious texts, myth, and/or folk lore. More information on the original can be found at Wikipedia.org.
- Krypton had its own Hell and demonic entities that were destroyed along with the planet. Rakkar the Nothing was the only known survivor who clung to Kal-El's vessel. He mentioned the Glass Lords, the Seven Courtiers, the Flame Brethren, the Corpse Mother and the Eret-Ha who all perished with Krypton's destruction.
