Vampires are undead Humans afflicted with a supernatural virus that drives them to drinking blood from the living, often using fangs to inflict wounds from which to obtain it. Vampires possess immortality, heightened senses, and supernatural powers of strength, speed, and mind control. Some Vampires struggled with Batman, most notably Dracula and The Monk. In The Batman vs. Dracula, Vampires are also implied to consume souls and flesh.
Batman would sometimes be afflicted by Vampirism and be transformed into a vampire for a short time.
On some Elseworlds, Batman is permanently a vampire.
