Batman's powers and abilities

Batman has retractable fangs inside his mouth that allow him to pierce the skin of humans, typically at the neck, and extract their blood. Batman requires blood to survive, though it is mentioned that it need not be human blood; it is mentioned that he has fed on rats in the past, and that he normally survives on artificially-created plasma. Blood appears to be the only sustenance he can consume. Unlike a "real" vampire, it is unclear whether feeding on blood heals Batman's injuries or in any way enhances his health and vitality.
