Vampires are folkloric creatures, typically held to be the re-animated bodies of human beings and said to subsist on human or animal blood.
And they have unnatural powers, and ability to physically transform.
Some cultures have myths of non-human vampires, such as demons or animals like bats, dogs, and spiders.

They are ageless. But once they are exposed to the sunlight they will be reduced to ashes.
They are weak in the cross and garlic. And they will die by being driven a white stake into their hearts.
