Demon

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.^[1] The Ancient Greek word δαίμων daimōn denotes a spirit or divine power, much like the Latin genius or numen.^[2] 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,^[3] a demon is believed to be a spiritual entity that may be conjured and controlled.
