Morrigan Aensland is the main protagonist of the Darkstalkers series. She may be a demon, but she is not evil. She is a succubus, a human demon with the power to steal the souls of those she seduces. However, unlike traditional succubae, Morrigan can sustain herself by secreting a special liquid when she is physical and mentally excited. She made her first appearance in Animated vs Video Game Villains War.
