Demons are a common antagonist in horror movies, often taking the form of supernatural creatures with evil intentions. They are usually depicted as powerful and malevolent entities that seek to cause chaos and destruction. In some cases, they may even be the source of the horror movie's plot. The term 'DEMONS' is derived from the Greek word 'daimon, ' which means 'SPIRIT.' DEMONS have been featured in many horror films, such as The Exorcist, The Omen, and The Conjuring.
