Olympos XII

The Olympos XII (オリンポス十二神) are a group of twelve Mega-level Shaman modeled after the Roman version of the, the "". The Olympos XII possess ability rivaling that of the Royal Knights, and each protects its own domain while maintaining a position of neutrality regarding the incidents which arise in the Digital World. They are led by Jupitermon and seek to punish evil, but some similar Digimon with the same goal, like Plutomon, are excluded from their number due to their cruelty in pursuit of that goal. The forces that defy the will of the Olympos XII and oppose them in battle are never-ending, to the point that the hatred of the Digimon they've defeated has been reborn as Titamon, who seeks to have their heads.

Development
When Digimon World Re:Digitize: Decode was in development, the producer Kazuma Habu requested Kenji Watanabe to design a Digimon that was both a member of the Olympos XII and Ogremon's Mega form. This Digimon was originally planned to be Bacchusmon and take design cues from the mythological, however, because it was hard to incorporate wine-based elements with Ogremon's design, the Digimon was redesigned to focus just on being Ogremon's Mega form, but they still wanted to connect it to the Olympos XII. Watanabe based this Digimon's relationship to the Olympos XII on, where the Twelve Olympians and the were enemies, and, because Ogremon was "quite titan-ish", the Digimon was named Titamon.
