The Succubus is a secondary villainess in the 1997 Playstation action-platformer "Castlevania: Symphony of the Night", aka. "Akumajou Dracula X: Gekka no Yasoukyoku" (悪魔城ドラキュラX 月下の夜想曲).
A minion of Vlad Tepes Dracula, the succubus quite ignorantly mistakes his son and protagonist of the game, Alucard, as just another mortal who has fallen asleep in his castle. Alucard has a nightmare in which he relives the sight of his mother, Lisa, being executed during the witch trials. The woman is quickly revealed not to be Lisa, but rather the succubus, with intentions of tormenting the hero. It is only after being defeated by him that the villainess finally realizes who he is, but by that time it is too late. Alucard kills her for her actions.
