Demons are malevolent spiritual entities created by Lucifer. Created from corrupted human souls after extensive torture in Hell.

Most demons forget what it means to be human. Some have even forgotten that they were once human. In general, demons engage in torture and destruction because it is fun or to avoid being tortured themselves. Some demons, however, are true believers in Lucifer's agenda to "cleanse" Earth, and actually consider themselves morally superior to humans.

Once a soul becomes a demon, it gains the basic demonic powers (possession, superhuman strength, etc.) and from there, it can work its way up the ladder to positions of greater authority and power within Hell (possibly by torturing other souls).

Types of Demons

Black-Eyed Demons
The most common class of demons on the show, black-eyed demons possess only basic powers, such as super-strength and telekinesis.

Crossroad Demons

Crossroad demons have red eyes. Unlike normal demons that serve the King of Hell, Crossroad Demons tend to be more self-serving, often bargaining with desperate people, making deals in exchange for their souls after a certain amount of time (usually ten years). They can grant wishes, collect souls, teleport, and be summoned by digging a hole in the center of a crossroads and burying a box with a picture of the summoner, some graveyard dirt, and a bone from a black cat. Gifted with immense power, these demons usually possess attractive women to lure men into making deals, although there are exceptions.

Cambions

Cambions are a demon race that are half demon but are also half human, they are created when a demon reproduces with a human, via there vessel.
