Profile

Origin

In the Babylonian creation myth, Tiamat^[a] (from the Semitic root t-h-m, meaning "sea") is the primordial sea goddess and personification of the chaotic saltwater ocean. Together with Abzû, the god of freshwater, she fills the cosmic abyss with the primeval waters and gives rise to the first generation of deities in the Babylonian creation epic Enûma Elish (“When on High”). She is described as female and is depicted with both anthropomorphic features, such as breasts, and theriomorphic traits, including a tail. She is also called Ummu-Hubur ("Mother-Watercourse"), credited with forming all things.

With Abzû, Tiamat mothers the elder deities Lahmu and Lahamu, who in turn give birth to Anshar and Kishar, personifications of the horizons of heaven and earth, and ultimately to Anu (Heaven) and Ki (Earth), establishing the divine genealogy of the Babylonian cosmos.

According to the myth, the younger gods' noise disturbs Abzû, who plans to destroy them. The god Enki (Ea) learns of this and captures Abzû, imprisoning him beneath his own temple. Enraged by her consort's defeat, Tiamat wages war against the younger gods, creating an army of monsters and elevating her son and consort Kingu as their leader, granting him the Tablet of Destinies as a symbol of supreme authority. The gods ultimately choose Marduk as their champion. In the ensuing battle, he defeats Tiamat, splits her body in two, and fashions the structure of the cosmos from her remains, forming the heavens and the earth, while her eyes become the sources of the Tigris and Euphrates rivers. After seizing the Tablet of Destinies from Kingu, Marduk establishes himself as king of the gods, and humanity is later created from Kingu's blood to serve the divine order.

Tiamat's battle with Marduk is widely regarded as the earliest recorded example of the Chaoskampf myth motif, in which a hero deity defeats a primordial chaos monster to establish cosmic order. The epic's central theme is the legitimization of Marduk's supremacy within the Babylonian pantheon, though scholars have noted that the narrative likely draws on earlier Mesopotamian traditions.^[1]

Design

In Digital Devil Story: Megami Tensei II, Tiamat is depicted as a red wingless dragon.

In Shin Megami Tensei II, Tiamat is given her first major design by Kazuma Kaneko as a monstrous woman covering in blue scales with green hair, three pairs of breasts and serveral white snakes coiling around her body.

In Devil Summoner: Soul Hackers, Tiamat is given her second major design by Kazuma Kaneko. This design bares multiple similarities to the one from Shin Megami Tensei II, namely that she has the body of a large blue skinned woman with three pairs of breasts, however she now has the armless body of woman emerging from the neck of the large body from the torso up and multiple snake like tentacles emerging from the waist of this second smaller body. The head of this new body has four yellow eyes and hair in a fashion similar to depictions of women from ancient Babylon and surrounding cultures. According to Kazuma Kaneko, he designed her head to create a Trompe-l'œil effect resembling a feminine figure.^[2] Her skin is also given a texture resembling water rather than the scales of the previous design.

Tiamat was given a drastic redesign in Shin Megami Tensei V: Vengeance by Masayuki Doi to match her role in the story. She is depicted as an enormous serpent with the head of a goat, dragon, and camel emerging from her neck, each one with a pair of golden fins on the side of its face, while also having a humanoid body resting atop them. Her humanoid body is armless similar to her Soul Hackers design, however while fused to her serpent body a pair of legs and be seen giving the appearance of her sitting on the serpent with several tail like tentacles around her waist resembling a dress, and her head is completely devoid of features aside from her eyes and a pair of upwards pointing horns. Her body is entirely black with golden accents, and her serpent tail is lined with multiple growths that resemble breasts. Tiamat is notable for being one of the largest demon in the game, towering over the player character and other demons.

This section contains spoilers. (Skip Section)

Tiamat is the goddess and mother of the Qadištu, worshiped as the Primordial Serpent. In eons past, Tiamat ruled over the universe in a state of primordial chaos until the Babylonian god Marduk sought to claim the Throne of Creation, killing her and establishing the rule of the Horned Gods.^[3] Any gods of Tiamat's lineage were barred from claiming the Throne by a curse placed on it by Marduk, ensuring that only those of his own lineage would have the right to create a new world.^[4]

At the start of Vengeance, the Qadištu and their allies seek to resurrect Tiamat and are relentlessly collecting Magatsuhi to offer power to Tiamat. As she is a Divine Dragon, the spell to undo her death requires the sacrifice of a Divine Dragonslayer. As such, after encountering the Nahobino he is targeted for this purpose, as he carries the Knowledge of Susano-o.^[5] After the confrontation between the Qadištu and the Nahobino in the Serpent's Grave, Naamah, Eisheth and Agrat sacrifice themselves along with the Nahobino to complete the summoning, with Aogami being consumed but succeeding in preventing the protagonist from also being absorbed into Tiamat.

Upon her resurrection Tiamat lays waste to Shinjuku with her Annihilation Ray, killing Nuwa in the process before disappearing, guided to the Throne of Creation by Yoko Hiromine in order to destroy it. She reappears when the Nahobino, now fused with Tsukuyomi, arrived before the Throne of Creation. If the Nahobino is Law aligned, Yoko will furiously trap both him and Tao in the Serpents Grave and unleash Tiamat on them in order to destroy the system, while if the Nahobino is Chaos aligned Mastema will appear and wrest control of Tiamat away from Yoko and drag them into the Serpents Grave to be killed for defying his Lord. After the boss battle in both routes, the Nahobino is unable to kill Tiamat due to her primordial nature making her immortal.^[6]^[7] She attacks with her Annihilation Ray, fatally wounding Tsukuyomi as well as whichever goddess the protagonist sided with and leaving the protagonist defenceless. However the battle against Tiamat granted Aogami's magatsuhi the chance to escape Tiamat, allowing him to reform and reunite with the Nahobino once again. Due to Aogami being a Divine Dragonslayer by virtue of being Susano-o reborn, he and the protagonists combined power is able to bypass Tiamat's immortality, and once they re-fuse they kill Tiamat with a single strike from their Murakumo.^[8]
