Catherine (キャサリン Kyasarin) is the titular character of the game Catherine, and a major character in the novels Catherine: The Novel and Catherine: The Mysterious Tale of Rapunzel. A mysterious young beauty, Catherine falls in love with Vincent Brooks which becomes the catalyst of the game's story. She works as a video game developer at a technology company called Fowles Electronics where she has worked on a "peeping tom dating sim" video game. Her seductiveness is more than just an act. In actuality, it is revealed that Catherine is a demonic succubus from the Underworld and the daughter of the Mesopotamian god Nergal. In her free time, she seduces men by shapeshifting into their ideal woman, and then kills them by dooming them to their nightmares. It is unknown if she is a rapist or a consensual succubus. Although many would call her "evil", her mission is to help clear the world and human gene pool of unfaithful cheating men. Catherine is a playable character in the DLC of Catherine: Full Body.
