Vampire

Vampires are a dangerous type of undead. Whilst humans are the most common victims of vampirism, it can infect other species as well, including hounds and even dragons. Throughout the multiverse, vampires can be created through other vampires transforming their victims, or through enchantment.

The most defining characteristic of vampires is their hunger for the blood or lifeforce of others, despite not having any blood of their own. Other traits of vampires can include unnatural physical strength, enhanced healing powers and the ability to fly, with the method of flight being through either natural or magical means. Many vampires are highly sensitive to sunlight and therefore only go out at night or in the shade, but this is not always the case. Regardless, the secretive and predatory nature of the creatures means that they all prefer the cover of darkness. Vampires can range from being mindless predators to sophisticated and intelligent nobles. The appearance of vampires is similarly varied, although they all have at least two elongated fangs and the more feral ones have bat-like qualities.

The Moroii from Ravnica are psionic vampires, draining the youth and mental abilities of their victims for sustenance. They are employed by House Dimir as assassins and spies (although they employ traditional blood-drinking vampires as well). They are unaffected by sunlight. Some look like Humanoid bats while others, such as Szadek and Mirko Vosk, could pass as humans. Refferences:
