The Beldam from Coraline

Implied to be a demon born from longing to have something to love, the Beldam, also called the Other Mother, in the book Coraline is the main antagonist. She copies the world Coraline lives in and coaxes her to enter her counterfeit world. But her behavior, coupled with her want for Coraline to replace her own eyes with black buttons, turns Coraline off and causes the girl to go home. Unused to getting what she wants, the Beldam abducts Coraline's parents so she'll be forced to return to her. It's revealed that the Beldam has no true understanding of unconditional love and quickly reveals herself as a hideous and horrendous monstrosity and tries to keep Coraline from escaping her by force. The Beldam could be seen as a sign of abuse; kind and caring at first, but quickly becoming violent and insane when she feels control is being taken away from her.
