Tiamat

Tiamat, appearing as Beast II in Fate/Grand Order, is a primordial deity from ancient Mesopotamian mythology, also known as the Goddess of Beginning and the embodiment of the primordial sea. In the game, Tiamat is depicted as a formidable enemy with the power to manipulate the Sea of Life and self-modify. Once the mother of gods, she harbors resentment towards humanity for being abandoned. In the Fate/Grand Order story, she transforms into a colossal monster symbolizing the return to bestiality, aiming to erase human civilization. Like other Beast-class enemies, Tiamat is an incredibly powerful and threatening presence. She has multiple forms in the game, including the larva form Larva/Tiamat, each with unique abilities and skills. Her complex backstory, immense power, and complicated relationship with humanity make her a memorable character in Fate/Grand Order.
