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.
