Myotismon is a Ghost Digimon. As the king of Undead Digimon, it was resurrected through the dark arts and obtained mighty powers. Originally a fiendish computer virus which destroyed the computer data it absorbed, it possessed the ability to revive the destroyed data as malignant computer viruses. As it possesses an extremely cruel and cunning personality, it is exceedingly difficult to destroy this Digimon.
