Myotismon, known as Vamdemon in the Japanese version, is one of the major antagonists in the anime, Digimon. He is perhaps the most evil of them all, and if a "main villain" for the entire first two seasons could be named, it would be Myotismon; if one were to be picky, one could say Myotismon is the Big Bad of the entire Digimon Adventure. He also reappeared in the video game, Digimon World Data Squad, and in the anime Digimon Fusion (season 3).
