Seraphimon

Seraphimon is a Great Being who was against the Uterio War, and was apprehended for it. After being released after the war's end, he decided not to care if TPK took control of the Great Beings and buggered off.

Along with Arceus and Michael Weston, Seraphimon was recently abducted by DU Monarch and placed inside the UG for an unknown reason.
