Unlock Description Translation🛈
Default メソポタミア神話における創世の神のひとり。



NA Localization: One of the gods who created the world in Mesopotamian myth. The gods were born from Abzu (fresh water) and Tiamat (salt water).
Afterward, the gods rebelled against their father, Abzu, and gained control of the world.
When this happened, Tiamat kindly watched over her children. This was proof that her love for her children exceeded her love for their father.

However, the gods eventually turned their blades on even Tiamat. She mourned and went mad, and created the monstrous Eleven Offspring of Tiamat to battle the gods.
At the end of the battle, Tiamat and her Eleven Offspring lost.
The gods split her corpse in two to make the heavens and the earth. This is said to be the ritual that created the human world.

Fan Translation: One of the creator deities of Mesopotamian myth.
The gods were born from the union of the freshwater Abzu and the saltwater Tiamat. Then, the gods rebelled against their father, and seized authority over the world from him.
Tiamat quietly approved of her children’s actions. It was proof that her love for her children outweighed her love for her husband.

However, the gods then turned their blades on Tiamat. Tiamat wailed and raged, birthing eleven new Magical Beasts to oppose the gods.
At the end of the war, Tiamat and the Eleven Beasts were destroyed.
The gods split Tiamat’s corpse in two and used them to form the heavens and earth. It is said that this ritual created the world of humans.

Bond 1 身長/体重:160cm~7400万km2・??kg

属性:混沌・悪  性別:女性

NA Localization: Height/Weight: 160cm – 7,400,000km2 ?? kg
Origin: Ancient Mesopotamian Mythology
Region: Mesopotamia
Alignment: Chaotic-Evil
Gender: Female
The black mud’s dimensions should be included in Tiamat’s own. But since the mud is of the void element, it cannot be weighed. At the same time, its internal capacity is infinite. It’s essentially a four-dimensional pocket space.

Fan Translation: Height/Weight: 160 cm ~ 74000000 km²・??kg
Source: Ancient Mesopotamian Mythology
Region: Mesopotamia
Alignment: Chaotic ・ Evil
Gender: Female
The black mud is also included in Tiamat’s height. However, the mud is made of imaginary numbers, so her weight is unquantifiable.
Meanwhile, Tiamat’s volume is infinite. In other words, she is a four-dimensional pocket.

Bond 2 創世後に切り捨てられた母胎。



NA Localization: A womb abandoned after the creation of the world.
The "Primordial Sea" that was used as the fertile soil which created life, but when Earth's environment settled down and ecosystems were established, she was banished to the world of void space (the world on the other side, a world of the void without life that isn't even a parallel world).

...Since she created life at random, now that ecosystems exist, she is no longer needed. As life on this planet began the process of gaining sentience, she could only hinder things. Ever since her banishment, Tiamat waited in the world of the void for a chance to return to Earth.

Fan Translation: Tiamat is the womb that was cast aside after the world was created.
She is the Maternal Sea who was used as the soil to give birth to life, but once the Earth’s environment settled and ecosystems were established, Tiamat was deemed unnecessary and driven out into the world of imaginary numbers. (The Inner World. Lifeless imaginary number space, not a parallel universe.)

Because the Earth’s ecosystems were established, Tiamat, who randomly designs life, was no longer needed.
The goddess became nothing more than an obstacle to the process by which life forms acquired the intelligence determined by the planet.
Since then, Tiamat has been waiting in the world of imaginary numbers for her chance to return to Earth.

Bond 3 【クラススキル】




NA Localization: "Class Skills"

Authority of Beasts: A
Also called an "anti-humanity" skill. She gains a special attack bonus against anything born from a womb, be it Heroic or Divine Spirit. This skill is given not only to Beast II, but to all the monsters she creates as well.

Self-Manifestation: B
A skill that allows one to manifest in the world without outside help.
Once she manifests, she spends seven days taking over the Indian Ocean. She continues making monsters from the moment of her manifestation to devour humanity.
At the same time, Beast II herself is the sea, so she cannot come on land.
Exterminating humanity is the job of her children, the monsters.
Also, since this skill indicates that she exists across all of space-time, it can cancel out any attacks that use time travel or time paradoxes, as well as any instant death attacks.

Self-Modification: EX
She can use the Chaos Tide to modify her own Spirit Origin.
She can switch from her normal Spirit Origin (Femme Fatale) to a massive dragon over sixty meters tall. In her dragon form, Tiamat nullifies any attacks below A++ rank.

Fan Translation: [Class Skills]

Authority of the Beast: A
This can be considered an anti-humanity Skill.
It is an ability that is especially effective against Heroic Spirits, Divine Spirits, and all things born from the mother’s body.
This Skill is not possessed solely by the Second Beast, but also by all Magical Beasts she gives birth to.

Independent Manifestation: B
The Skill to manifest independently in the current world.
Seven days after manifestation, the Indian Ocean will be smothered black.
Once Tiamat manifests, she unceasingly gives birth to Magical Beasts and sets out to devour humanity. However, the body of the Second Beast is the ocean itself, so it cannot move onto land. Instead, it is her children’s role to mop up the human race.
Furthermore, this Skill is an expression of the holder’s presence across all of space-time, rendering her immune to attacks by methods such as time travel paradoxes, and canceling out all instant death attacks as well.

Self-Modification: EX
Tiamat can remold her own Saint Graph using the Black Sea of Life.
Her body can grow from its standard Saint Graph (Femme Fatale) into that of a dragon over 60 meters in length.
Once Tiamat becomes a dragon, attacks against her of A++ rank or lower are nullified.

Bond 4 ○生命の海:EX




NA Localization: Primordial Sea: EX
Beast II is the sea that brings forth life itself.
Since it circulates with true ether from the time of the planet's creation, an infinite supply of magical energy is available within it.
Anyone who is trapped within the black mud and sinks into the sea is randomly given skills such as Self-Modification, Bio-Alteration, Bio-Fusion, and Replication. When they return from the sea to the land they are forced to receive a geas from Beast II at the cellular level... a DNA contract (Amino Geas), and automatically become an enemy of humanity.

Nega-Genesis: A
The same type of skill as Beast VI's Nega-Messiah.

A conceptual barrier that overturns everything modern science thinks it knows about the Theory of Evolution and the creation of the Earth. When Beast II is protected by this skill, she gains a powerful resistance to any Noble Phantasms wielded by Servants from humanity's proper history.

Monstrous Strength: A++
Her ability as a monster. Increases her strength.
Close to the highest rank. With the black mud and dragon body she uses in this manifestation, Tiamat has the strength of a giant.

Fan Translation: Sea of Life: EX
The Second Beast itself is the sea which gives rise to life.
It cycles the True Ether of primordial Earth, so its mana supply within this sea is infinite. All who are caught and drowned in the black mud are randomly assigned the following Skills: Self-Modification, Life Transformation, Life Fusion, and Individual Multiplication.
Once these organisms exit the sea to make landfall, they are forced into a cellular-level geis — a nitrogenous base contract (amino-geis) — and automatically become enemies of humankind.

Nega-Genesis: A
A Skill of the same type as Nega-Messiah, which is possessed by the Sixth Beast.
It is a conceptual bounded field which completely overturns modern evolutionary theory and the predictions of Earth’s genesis.
Thanks to this ability, the Second Beast has acquired a strong resistance to the Noble Phantasms of Servants created by correct human history.

Monstrous Strength: A++
One’s ability as a monster. This Skill raises the user’s Strength.
It is at about the highest possible level. This is why Tiamat’s Strength is that of a titan when she makes the black mud into her body and manifests in her draconic form.

Bond 5 人理定礎の崩壊、そして聖杯の力によりこちらの世界に帰還を果たしたティアマトは、しかし、深い微睡みの中にいた。





NA Localization: Tiamat returned to the world after the collapse of the Foundation of Humanity, and with the power of the Grail. However, she was in a deep sleep. This was due to Merlin's spell, but even so, Chaldea's attack awakened her and caused her to instinctively attempt to wipe out humanity.

Part of this was due to her rage, hatred, and sorrow at being abandoned once she was no longer useful. But it was also an attempt to feel the joy that would come if she were to recreate Earth's ecosystems and once again become the mother of all things.

This nature was what decided her Class.
Her True Name is not "The Goddess of Creation."
She is a great disaster, the most rejected being in all of human history, and something that humanity long ago left behind.

Her name is Beast II.
One of the Seven Evils of Humanity, and a beast which possesses the law of Recurrence.

Fan Translation: With the collapse of the cornerstone of the anthropic principle, Tiamat managed to return to this world with the power of the Holy Grail. And yet, she was in middle of a slumber.
Setting aside wherever it was caused by Merlin’s magecraft, she awoke from that sleep due to the attack from Chaldea and set out to eradicate mankind in accordance with her instincts.

While there is resentment・hatred・sadness for being discarded as someone who had already served her purpose, this is also a deed of indulging in the “joy” of once again repainting the Earth’s ecosystem and having everything come back to the mother.

Her Class was determined by this true nature described above.
The goddess of Genesis and the likes are nothing but fake names.
Deserted by humans, this is one of the most rejected great disasters in human history.

Its name is Beast II.
One of the seven human vices, the beast carrying the principle of "regression."

Extra 人格らしきものは確認できない。



NA Localization: It is impossible to confirm any sign of personality within her.
Perhaps she's lost her ideals, or perhaps she never had any reason to begin with. It could be either.
Her sole reason for existence is to bear and raise children, and then love them. But when this was taken from her, she began a war against a humanity that decided she was no longer needed.
Her internal systems run off a very primitive principle: if she does not exterminate humanity, she will be killed.

Motive/Behavior Towards Master
One of 7.2 billion. A target for annihilation.
To humanity, Beast II is a terrible invader.
But at the same time, to Beast II, humanity is a terrifying invader.

Fan Translation: It is impossible to confirm if Tiamat possesses anything resembling a personality.
Perhaps she lost her intellect, or perhaps she never had one, to begin with. Either is acceptable.
The only meaning of her existence is to create, raise, and love her children. Thus, she set out to make war against humanity for declaring that it has no need for her.
It is the functioning of an extremely primitive system: “If I do not exterminate modern humanity, I will be killed.”

Motivations・Attitude towards the Master
One of seven billion. An obvious target to be obliterated.
While the Second Beast is a repulsive invader to humanity, humans are terrifying aliens (extraterrestrials) to the Second Beast.


  • Tiamat is the antagonist of Babylonia. She, like all Beast-class servants, is currently unobtainable.
