Vampire

Vampires, or vampyres, were a class of undead, supernatural beings. They exhibited a range of traits in various varieties across the Multiverse.

The Invisible Vampyres of Sanguivor were, as their name implied, invisible. They were beastly creatures who usually killed their victims. However, a non-lethal bite from them would result in the victim beginning to turn into a vampire themselves. They would have the ability to turn invisible too, but remain more human and intelligent than normal Sanguivorian vampires, as demonstrated by Acantha.

Some vampires, including victims of the Sanguivorian vampires and the vampires of the 819th Universe, could also turn into bats at will. (PROSE: Century Smith and the Time Terror)
