Galamton

"The purpose of Ouma, which is to merge the different worlds together, is my primary goal and the one that influenced the creation of the group itself. Your ancestors were foolish enough by sealing me in a dimensional prison, Reiji Arisu. It doesn't matter how much time passes, i'll break free to bring sorrow and chaos in my path, for i am Galamton, the multiversal demon, and Ouma's source of life, the one who'll bring them back no matter the times they get annihilated!."

- Galamton revealing his and Ouma's origins to Reiji's group in the final chapter.

Galamton is the final boss of Project X Zone 3: Sacred Destinies, he is a multiversal demon who is responsible not only for the events of the game, but also is responsible of Saya's many resurrections.
