Nega Filgaia was the creature Beatrice created to be the ultimate life form and Filgaia's counterpart. Nega Filgaia is the conclusion of Beatrice's schemes. Its creation required enormous quantities of energy, so Beatrice took all the energy scattered from the destruction of the Nightmare Castle. This energy channeled into the Yggdrasil Generator and fused with every person of Filgaia´s memories gave birth to Nega Filgaia.
