Moon=Millenniummon

Moon=Millenniummon is an Evil God Digimon whose name and design are derived from "-Millenniummon". It is a soul Digimon that exists within Millenniummon's inner world. As a result of Millenniummon's dark spirit becoming a Digimon, it does not possess a fixed form, and although it often takes the shape of a crystal, it seems that the hatred and anger it feels against those who oppose it cause it to change shape. As it is a soul and does not have substance, it is immune to physical attacks. To defeat Moon=Millenniumon, one must first defeat Millenniummon, its true form, but it's likely there are virtually no Digimon who are up to that task; even if Millenniummon is somehow defeated, it is said that Moon=Millenniummon will separate from its now-dead physical form and be revived throughout time and space.
