Dolly

Dolly was the main villain of the horror movie Dolly Dearest, although technically she was one of many possessed dolls in the movie - however their was a singular "Dolly" that seemed to have more hold over her human victims than the others and thus could arguably be the prime villain of the mob of demons.

Dolly and her many minions were the creations of Elliot Wade, an American who had gained possession of the Dolly Dearest doll company in Mexico and moved his family out in order to oversee the project - however he was unaware that evil spirits had been disturbed from the site of a Mayan cult, these roaming spirits quickly found a vessel to enter the mortal world in the form of the many dolls Elliot had made: much like in Child's Play Elliot gave one of the dolls to his daughter to keep - this doll is known as "Dolly" and acts as the main villain since she tries to possess Elliot's daughter and corrupt her innocence.

After a few grisly murders however Elliot and his family become aware of Dolly and her plans, they fight back - climaxing in them blowing up the Dolly Dearest factory with dynamite: as Dolly and the other dolls explode the evil spirits are dispersed and peace seemingly restored to the area.
