Dianamon

Dianamon is one of the Olympus Twelve, and the Mega form of Lunamon. She is named after Diana, the Roman goddess of the moon and the hunt. She makes her first appearance in the games Digimon World Dawn and Dusk.

Like the two sides of the moon, Dianamon also has two different characters. As an Olympus Twelve, she takes charge of water and ice, and can battle even under absolute zero. On her legs are the "faces" named Goodnight Sisters.
