Myotismon

Myotismon (voiced by Richard Epcar) is one of the many villains in the Digimon franchise. His goal was to rule both Digimon and human world. He had many Digimon henchmen, including Gatomon. He went to the human world to try to find the eighth Digi-Destined and destroy her. After he discovered that Gatomon is the Digimon to eight child, he used her to find the Kari, and planned to destroy them both. After Myostimon killed Wizardmon, Gatomon was able to digivolve into Angewomon and destroy Myotismon.
