Larva Tiamat

Larva Tiamat, Class Name Alter Ego, is an Alter Ego-class Servant summoned by Ritsuka Fujimaru in the Grand Orders of Fate/Grand Order Arcade. The Beast of Creation, Tiamat, manifested in a juvenile form; an Alter Ego she created with the purpose of "resetting oneself and being reborn." She is said to still be rather upset over her past defeat in the Babylonia Singularity, but has chosen to set it aside in order to ensure that her children are not wiped out.
