Myotismon

Myotismon is an Undead Digimon whose name is derived from Myotis, a genus of bats (his Japanese name is a concatenation of "vampire" and "demon"). His design is derived from the Vampire.

Myotismon is a vampire dressed as an elegant gentleman, and feeds on the fresh or deleted data of his victims, who were thought to have been afflicted with sudden anemia. His power is decreased in the presence of the sun, so he creates a fog around him wherever he goes. He has demonstrated telekinetic abilities.
