Dianamon

Dianamon is a God Man Digimon. It is one of the Olympos XII, presides over water and ice, and is able to fight even when the surroundings are below. Just as the moon has two sides, light and dark, its personality is of a two-sided nature, and its beauty conceals a terrifying power. It wears the "Goodnight Sisters" on both of its legs.
