Mephismon

A Fallen Angel Digimon which has the appearance of a giant ram. It is also a dark being born from the lingering thought-data of an Apocalymon that attempted to destroy all life. Like Apocalymon, its governing principle is the extermination of all life. It specializes in the black magic of the Dark-species, and its personality is endlessly cruel. However, it is highly intelligent, and is also a tactician. Its Signature Move "Black Sabbath" is a dark incantation in which it prays for a festival of death. Those who hear this spell will soon die. Its Special Move is generating a cloud of darkness which causes everything to decay (Death Cloud).
