Olympos XII

The Olympus Twelve (オリンポス十二神) are a group of twelve Mega-level Shaman Digimon modeled after the Roman version of the Twelve Olympians, the "Dii Consentes". The Olympus Twelve possess power rivaling that of the Royal Knights, the guardian deities of the Net, and although they defend the same domain, they are enigmatic, shadowy beings who maintain a neutral standpoint towards the incidents that arise within the Digital World.

Most of the members of the Olympus Twelve resemble a human wearing armor based on a specific animal, and they usually have a named jurisdiction. The group is primarily a facet of the Digimon Card Game, although Merukimon is a major character in Digimon Data Squad anime and the four then revealed members appeared in the game Digimon World Data Squad. A Neptunmon, Marsmon, and Apollomon are also members of the Bagra Army, and a Mervamon is a member of the Xros Heart United Army in Digimon Xros Wars, although they are not stated to be members of the Olympus Twelve.

Only nine members of this group have been announced thus far.

Remaining members
Because there are several versions of the Twelve Olympians in Greco-Roman mythology, it is not entirely certain which members the remaining three to four Digimon will be based on. According to the classical scheme, the remaining members would be "Jupitermon", "Junomon", "Ceresmon", and "Vestamon". This scheme also has Vesta later giving her seat to Bacchus, so it is possible that "Bacchusmon" could be used in place of "Vestamon". Some schemes also would include "Plutomon", though it is unknown who he would take the place of.
