Vampire
Vampires, or vampyres, were a class of undead, supernatural beings. They exhibited a range of traits in various varieties across the Multiverse.
Nature
Powers and limitations
In at least one universe, it was possible to turn into a vampire over time after being bitten by a regular vampire, but this was not a given. These vampires needed human blood to survive, and did not drink any other beverages. They were invisible in mirrors (PROSE: Camera Shy) and weak to direct sunlight, their skin beginning to burn after a few seconds of exposure, though they could quickly recover from this if taken back into shade. (PROSE: Parallax, COMIC: A Letter From Beyond) In another universe, vampires needed human blood to survive, though a synthetic substitute existed, but they could walk in the sunlight unprotected with no visible ill effects. (COMIC: Infinity Apartment)
Physical traits
Many vampires had sharp canines, which were more properly referred to as fangs instead of teeth. (PROSE: Century Smith and the Time Terror, COMIC: Infinity Apartment, Jenny Everywhere in the House of Terror) Some had unusually-coloured eyes: Alan's were golden, (COMIC: Infinity Apartment) while the fake Dracula appearance once used by Strach had eyes with yellow “whites” and red irises. The latter also had pointy ears. (COMIC: Jenny Everywhere in the House of Terror) Ibdis had extremely pointy ears, as well as chalk-white skin. (COMIC: A Letter From Beyond)
Association with bats
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) Kim, a friend of Jenny's who had vampiric abilities, though she never called herself a vampire, had the ability to turn into a swarm of bats, which would pool together to reform into a single woman when she took human form again. (PROSE: Camera Shy) Alan, a vampire from yet another universe, could grow bat-like wings on his back at will, adjust their side, or put them away entirely. (COMIC: Infinity Apartment)
Specific types
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. (PROSE: Century Smith and the Time Terror)
