Demons are usually, but not always, malevolently evil. Christian Demons are considered to be either Fallen Angels or the souls of the human dead. They are God-haters and can appear in a variety of different forms including as humans, cats, and goats. Christian Demons have the ability to posess people. This posession can result in the host foaming at the mouth, screaming obscenities against God, vomiting strange objects, and posessing super-human strength.
