World of the Rider War
Formica Regia was among four Lords who were part of a gathering of monsters which were revived by Super Apollo Geist in the World of the Rider War through a surplus of Life Energy which he had gained during his wedding to the Fangire Queen. These four Lords were combined to create a copy of the strongest Lord from the World of Agito, Taurus Ballista. This Taurus Ballista is later destroyed by Hibiki.
