Wampire bats

Wampire bats are a mid-sized carnivorous bat species with an appearance similar to vampire bats. The two species are often confused despite having no range overlap. Wampire bats are immune to swords, and can be injured but not killed by other edge based weapons. Additionally, wampire bats have completely unique dentition among extant animals, with their teeth forming the shape of a face. The purpose of this is currently unknown; theories range from a method to scare off would-be predators to some sort of sexual selection mechanism.

Behavior

Wampire bats act in a manner similar to other bats. They are nocturnal and roost in caves or trees during the day. Wampire bats are ambush predators, they often hang in wait for prey to pass nearby. Humans who are bitten by a wampire bat will turn into a wampire. Wampires are resistant to swords, easy to store, and don't need food. However, they are weakened by the sun. Kings would turn their armies into wampires in order to gain the upper hand in battle. This was declared a war crime in the Geneva convention. Wampire bats only show up in mirrors when they are facing the mirror, otherwise they don’t show up at all. Wampires on the other hand, can be seen in mirrors.

Diet

Wampire bats eat raccoons, among other things. ^[1]

Range

Wampire bats can be found across the northern hemisphere, typically in places with adequate shelter. The introduction of raccoons into Europe has caused dramatic increases in the European wampire bat population.
