The Smile Entity

The Smile Entity, also known as The Monstrosity, is the main antagonist of Paramount Pictures' Smile franchise. It is an evil demonic entity responsible for an ongoing series of gruesome murders, which it facilitates through a “curse” which passes from victim to victim in a “chain” stretching back to an unknown beginning. When the demon first begins to manifest, it torments the cursed person over a prolonged period of time (almost a week) through illusions and various other malicious tricks before moving on to possess them, whereupon it will use the victim's body to commit suicide in front of a nearby witness, who then becomes the demon's next host. Before driving them to suicide, the demon always forces its hosts to wear a sinister, unpleasant smile. Some theories suggest the demon consumes the souls of its victims, adding to its collection of terrible grins in this manner. The demon can alter a person's perceptions to mislead them into thinking they’ve managed to beat it, before resuming the haunting as before. As such, the only way to be rid of this entity is to pass on the curse which carries it on to another person.
