Orochimon

Orochimon is a Demon Dragon Digimon whose name and design are derived from the mythical Orochi (『大蛇』). Orochimon is an ancient Digimon that used to rampage across the Digital World, until it was sealed by an "existence" that harmonized the area so that Orochimon couldn't annihilate it. Seven of Orochimon's eight heads are expendable, but the black head is not.
