A soul Digimon existing in Millenniummon’s inner world. This is the Digimon form of the darkness within Millenniummon’s heart, and thus has no set form. MoonMillenniummon often appears in the shape of a crystal, but its shape changes in response to anger or hatred toward its enemy. Also, it has no substance as a soul, and so no physical attacks affect it. One must first defeat the body of Millenniummon in order to defeat MoonMillenniummon, but Digimon up to that task are practically nonexistent. And even if by some chance someone succeeds in defeating Millenniummon, MoonMillenniummon is said to separate from this body, traversing time and space to revive. MoonMillenniummon’s special move Death Crystal lacks any corporeal destructive power, rather mangling the souls of hostile Digimon.
