A demon is a supernatural being, typically associated with evil, prevalent historically in religion, occultism, literature, fiction, mythology, and folklore; as well as in media such as comics, video games, movies, anime, and television series.
The original Greek word daimon does not carry negative connotations. The Ancient Greek word δαίμων daimōn denotes a spirit or divine power, much like the Latin genius or numen. The Greek conception of a daimōn notably appears in the works of Plato, where it describes the divine inspiration of Socrates.
In Ancient Near Eastern religions and in the Abrahamic traditions, including ancient and medieval Christian demonology, a demon is considered a harmful spiritual entity which may cause demonic possession, calling for an exorcism. In Western occultism and Renaissance magic, which grew out of an amalgamation of Greco-Roman magic, Jewish Aggadah and Christian demonology, a demon is believed to be a spiritual entity that may be conjured and controlled.

The Watcher, another group of demonic entities, known from the Enochian writings, appear in the canonical Book of Giants. The Watchers came into existence after the demons were chained up in the sky by Living Spirit. Later, outwitted by Third Messenger, they fall to earth, there they had intercourse with human women and beget the monstrous Nephilim. Thereupon they establish a tyrannical rule on earth, suppressing mankind, until they are defeated by the angels of punishment, setting an end to their rule.
According to Rosemary Ellen Guiley, "Demons are not courted or worshipped in contemporary Wicca and Paganism. The existence of negative energies is acknowledged."
