Demons

Demons are magical beings motivated by evil. These beings are the main antagonists during the series that the Charmed Ones have had to fight and vanquish since they seek out to kill innocents and spread evil.

Most demons live out in the Underworld, although straggler demons live amongst mortals. They mostly appear to be vaguely humanoid, some demons resembling actual humans ie. Zankou, while some appear to be nothing like them (eg. Manticores, Abraxas, etc...). Almost all demons possess some kind of teleportation power, notably shimmering, and an active offensive power such as Energy balls.

Demons are unable to feel human emotions (Prue vanquished Vinceres by forcing him to feel the world's emotions), and do not have souls. However, demons are not always inherently evil, although they are susceptible to it. Notable demons who have been good include Cole (for a time), the Manticore baby, Kira and Drake.

Low-Level Demons
Next to nothing in the hierachy are low level demons. Also called base-level demons, these are demons with basic powers and often little intelligence, which make them easy to be vanquished. These demons often are minions of Upper-Level demons or hired assassins such as Scather Demons, the Imp Master and his Imps, etc... . Though there are Low-Level demons who prefer to act alone, such as the Water Demon.

There are only a few Low-Level demons who have an entry in the Book of Shadows of the Charmed Ones.

Upper-Level Demons
Also called high-level demons, are demons who possess a great amount of power. They often hire Low-Level demons to do their dirty work and are often affiliated to The Source of All Evil or The Triad. Some of these demons are the Seer, Belthazor, Litvack, Raynor, and other Upper-Level Demons that only owe allegiance to themselves, for example, Zankou.

Most Upper-Level demons have an entry in the Charmed Ones' Book of Shadows, including information of their origin, specific motivation, and a complicated method of vanquishing them, which usually requires a potion made from their own flesh to work or a Power of Three spell.

Ordo Maloru
The Ordo Malorum were upper-level said to be the generals who lead the war against evil. One of them was Litvack. And other one of these demons once was in possession of Jinny, an upper level cursed to be a Genie.
