Beast II (ビーストⅡ, Bīsuto II?) is a Beast-class Servant who appears in the Grand Orders of Fate/Grand Order.



Beast II's True Name is Tiamat (ティアマト, Tiamato?), one of the Primordial Deities in Mesopotamian Mythology/Sumerian Mythology.[1][2] Before being called Tiamat, she was known as the Goddess of Beginning, the primordial sea, Nammu.[3] Along with Abzu, she was manifested from the Sea of Dawn (黎明の海, Reimei no Umi?)—an Ocean of Void (無の海, Mu no Umi?) that lies below the Underworld of Ereshkigal, said to have once been under the administration of the god Enki. [4]

In Sumerian Mythology, the gods were given birth from the pairing of Tiamat, who is the salt water, and Abzu, who is the fresh water. Afterwards, the gods, whom are their children, waved their banner of revolution against the primeval father Abzu and acquired supremacy over the world. At this moment, Tiamat gently approved the deeds of her children. It is proof that her love for her children has won over her love for her husband.[1][2]

However, the gods pointed their blades even at Tiamat, their mother. Tiamat, in her grief and disorder, gave birth to 11 Magical Beasts as her new children, and they altogether had a showdown with the gods. At the end of the conflict, Tiamat and her 11 Magical Beasts were torn apart. It is said that the gods tore up her corpse into two, forming heaven and earth from it, and thus, had established the ritual for the creation of the World of Man.[1][2]

Tiamat was “a womb discarded after the Genesis”, becoming the origin of Sumerian Mythology. She was turned into a “Mother Sea” and was put to use as a breeding ground to produce life, but once the earth’s environment stabilized and after the ecosystems were established, she was banished to the World of Imaginary Numbers (虚数世界, Kyosuu Sekai?) (a World on the Reverse Side (裏側の世界, Uragawa no Sekai?); an imaginary space that has no life and is not even a Parallel World) as something unnecessary. (Seeing that the ecosystem was already established, there is no need for her, one who designs life randomly, and it is said that regarding the course the lifeforms who acquired intelligence conforms to, she was nothing but an impediment by now.) Hereafter, Tiamat has been waiting in the mirror world for a chance to return back to her original world.[1][2]


After obtaining the Holy Grail that Goetia stored within the heart of Kingu, the Sea of Life (生命の海, Seimei no Umi?, localized as "Primordial Sea") initially manifests a human-scale body known as Femme Fatale (ファム・ファタール, Famu Fata-ru?). It appears as a woman with light blue hair clad in leg and arm restraints, with features that represent the planet, large horns that symbolize the land, and eyes that reflect the inner sea of the planet. Gilgamesh refers to this as Tiamat's Cerebral Corpus; it is suggested to represent whatever remains of Tiamat's mind or consciousness. Upon partial awakening,her Cerebral Corpus is stained in red and black in a manner reminiscent of Dark Sakura.

Following the annihilation of the Cerebral Corpus, the Sea of Life manifests Tiamat in the form of a Titan (巨人, Kyojin?)—later demonstrated to be capable of flight by the use of her Wing-Horns (角翼, Kakuyoku?). However, in the circumstance that Tiamat faces a severe threat, she enacts Self-Modification (自己改造, Jikou Kaizou?) and Saint Graph Dilation Operations
, Reiki Bouchou Koutei
?) to assume a Draconic Body (竜体, Ryuutai?)—referred to as her "true appearance". After the Draconic Body is imposed with the "Concept of Death" (死の概念, Shi no Gainen?) by the Old Man of the Mountain, da Vinci confirms that Tiamat's Saint Graph Core (霊基核, Reiki-Kaku?) is situated within its brain.[5]

To clarify, Tiamat's assumed appearances are, with the exception of her Draconic Corpus, said to express her existence as a Divinity (神性, Jinsei?, lit. "Divine Nature"). However, the assumption of her Draconic Body is described by Romani Archaman to entail an unveiling of her complete and unadulterated existence—moving him to distinguish it from Tiamat's other states as "the very Corpus of a God" (神の体, Kami no Karada?, lit. "Flesh of God"). Though Tiamat's combat capabilities and defenses are indeed the strongest upon assuming her Draconic Corpus, Jaguar Man comments that this is in reality Tiamat in her weakest, most vulnerable state.[5]

Owing to Tiamat's Authority (権能, Kennou?) over the Sea of Life and her capacity for Self-Modification, she is capable of freely remodeling her Saint Graph, and therefore is unrestricted to the appearances described above.

The Black Mud of the Sea of Life is also included in Tiamat’s height.[1] Her height matches the area of the Indian Ocean.[2] However, given that the mud is made up of Imaginary Numbers, her weight cannot be measured.[1][2] Essentially the same as zero.[2] On the other hand, its volume grows to be infinite. In short, it is a 4-dimensional pocket.[1][2]


Something like a personality cannot be confirmed from her. Whether Tiamat has lost her ideals, or whether she has no reason since the beginning, it can be interpreted as either way, but one cannot surmise the reason. Although she simply birthed, raised and loved her children, which was viewed as her only meaning in life, she has set out to fight against humanity, of whom they decided that for the sake of denying this meaning, they have declared “you are not needed.” Her behavioural ideology when becoming a Beast is extremely simple; she runs under the extremely primitive system of “If I do not kill humanity, I will be killed.[1][2]

Concerning Tiamat's motivation and attitude towards the Master, he/she is one of seven billion humans. Naturally a target for obliteration. As far as human beings are concerned, Tiamat is a repulsive aggressor (invader), but concerning Tiamat too, human beings are terrifying aliens (extraterrestrials).[1][2]

Because Tiamat cannot converse, her pronouns are unknown.[2]

In the Anime, Ritsuka Fujimura during the final battle against Beast II encountered a mental projection of Tiamat in her first form. Somehow she was able to make herself understood to him. Tiamat lamented that her children used her as a stepping stone, leaving her behind and that all she wanted was to be by their side.

After asking if her love was wrong, Ritsuka choose not to stab her like her previous children (the Sumerian Gods) and instead told her that her children loved her and that they had to "get going". In other words he thanked her for a Mother's Love as humanity grew up but now that they were adults she had to let them go.

"Please don't leave me. Please never... love me again."

In the end, Tiamat asked Ritsuka to not leave her behind and that if he (humanity) had to do so, to not love her again.


Fate/Grand OrderEdit

Babylonia: The Absolute Frontline in the War Against the Demonic BeastsEdit

While Beast II achieved her return to this world with the collapse of the Human Order Foundation and due to the power/distortion of the Holy Grail, she was however in the middle of a deep slumber. Setting aside the fact that Merlin's magecraft kept her asleep, once Beast II was attacked by Chaldea, she woke from her sleep and setted out to clean up humanity in accordance with her primal instincts.[1][2]

Although there is resentment/hatred/sadness for being abandoned for having already served her purpose, there is also a conduct in indulging in the “joy” of coming back to repaint the earth’s ecosystems once again as the mother of everything.[1][2]

Her Class was determined by her real nature mentioned above. The Primordial Goddess and the likes are but false titles. Deserted by the humans, that being is one of the great disasters most rejected by human history. That name is Beast II. One of the seven Evils of Man, the beast that carries the principle of “Regression”.[1][2][5]

Also, the title called Femme Fatale was something given by Beast I (Goetia). Goetia successfully saw the true nature of Beast II’s core, so he bestowed a title meant for a Woman of Destiny rather than one meant for a Mother of the Gods (Magna Mater). At the bottom of her hatred towards humanity, there is also joy towards humanity for becoming a mother, as well as love towards humanity, them being the children of her first-generation children. For this reason, Beast II binds herself. A mother’s love is something necessary for growth, but it is something unnecessary for adults. In order for humanity to advance to the next stage, they must overcome the “original woman”.[2]

Other appearancesEdit

In Fate/EXTRA CCC, Tiamat was mentioned in BB's Potnia Theron Skill. It is the authority of the Earth Mother Goddess whom BB compiled and absorbed from the abyss of the Moon Cell. It is the embodiment of the power of creation possessed by the mother goddesses, originating from a forgotten goddess approximately 8000 years ago (the goddess of Çatalhöyük), and branching to Tiamat, among other goddesses.[6]


Tiamat is said to be an "evil" Chaldea can't even imagine and a great demon that may even surpass the power of the King of Magecraft as claimed by Goddess Rhongomyniad.[7] Being a primordial goddess,[8] Tiamat's Magical Energy and firepower are incredibly vast. Without fully awakening due to being sealed, Tiamat is able to damage Chaldea's SHEBA 02, 06, and 09 by causing spatial rifts all over Mesopotamia and birth over one hundred million Laḫmu capable of spreading all over Mesopotamia in less than half a day.[9][8] After receiving the Holy Grail, Tiamat is only able to manifest her brain in the form of "Femme Fatale" due to the seal still restraining her arms and legs. In this form, Tiamat possesses an ultra-ultra-ultra-class Magical Reactor core with seven times the magical energy of a Holy Grail and can release from her body as much energy as a Hydrogen bomb. Dr. Roman also claimed that had she fired at that moment she would have blasted Uruk even from that distance.[10]

Tiamat's Titan Form 1

Tiamat's "Titan" form destroying Uruk

After voluntarily letting Ishtar destroy her body with An Gal Tā Kigal Shē, Tiamat restructures her Spirit Origin into a mega-structure post dispersion, increasing its scale. With an Authority that had not been seen since the era of Genesis, Tiamat also drastically increases her body mass.[10] In this "Titan" form, Tiamat is said to be a perfect being with no physical or mythical shortcomings,[11] with enough magical energy to travel between stars. In fact, not even aliens would be able to take her down. Even if both Quetzalcoatl and Ishtar had their full-powered authorities and the help of any other powers left in Mesopotamia they wouldn't be able to damage Tiamat.[10] Tiamat boasts impressive durability and even the combined efforts of Quetzalcoatl's Xiuhcoatl and Gorgon's Pandemonium Cetus are only able to destroy her right horn without her main body taking any damage.[12] In this state, Tiamat surpasses the power of any Heroic Spirit as even the Chains of Heaven formed from Kingu's Enuma Elish was only able to momentarily restrain her movements before she broke them, even though according to Gilgamesh that feat was equal to any other in Enkidu's life,[13] a being whose combat strength is roughly the same as that of Gilgamesh during his prime.[14] It is theorized that only Gugalanna, the greatest and strongest Divine Beast, would be capable of stopping her on her tracks for a day.[11]

Tiamat's Draconic Corpus Form 1

Tiamat's true form, "Draconic Body" corrupting the Underworld

Even at her weakest, wounded after falling to the Underworld and receiving Ereshkigal's punishment, Tiamat's Authority is still powerful enough to corrupt the Underworld by spreading at an enormous speed,[13] even though Ereshkigal is absolute law inside her domain and all deities are left powerless within it if she so chooses.[15] Even in this state, Tiamat is able to grow her Spirit Origin and reboot her magical reactor once more, healing all her wounds and manifesting her true form, "Draconic Body". In this state, her strength is like that of a giant and she becomes immune to attacks ranked A++ or lower.[1] She can no longer be considered a Servant possessing Divinity but only an actual deity.[13]

On top of her firepower, strength, and endurance, Tiamat lacks the concept of death and can heal herself from the Sea of Life over time rendering her virtually unkillable without being able to enforce the concept on her powerful Saint Graph. According to the Corrupted Ushiwakamaru, only a Noble Phantasm capable of gathering all the magical energy of the entire era would be able to destroy the Sea of Life. In other words, only the Bands of Light in the sky can rival Tiamat.[10] Even if her Sea of Life is completely destroyed, it will end up remerging from her body in a short while such as after being destroyed by Piedra Del Sol or after her fall to the underworld.

Tiamat is ultimately defeated in the Babylonia Singularity due to multiple factors. Mainly Merlin transforming the Sea of Life into flowers draining her power and King Hassan not only severing her wings but granting her the concept of "death" by downgrading her Saint Graph into that of a normal servant. These two attacks were able to weaken her enough so that the rest of Ritsuka's party could keep damaging her until Archer Gilgamesh ultimately dealt the finishing blow with Ea by destroying her weak spot in the head and therefore collapsing her Spirit Origin.[13]

Class SkillsEdit

Authority of the Beast (A Rank): An Anti-Humanity Skill that enhances the skill holders' capacity to harm Heroic Spirits, Divine Spirits, and all organisms birthed of the "Mother's Womb". This Skill is held not solely by the 2nd Beast but shared amongst all the Magical Beasts birthed of her womb.[1]
Independent Manifestation (B Rank): Lends the capacity to manifest independently within the temporal reality. Within seven days of manifestation, the Indian Ocean is smothered black; and Tiamat incessantly spawns Magical Beasts to the end of devouring humanity. However, as the body of the 2nd Beast is the ocean itself, it cannot make landfall. Therefore, the role of annihilating humanity is delegated to her children. At this rank, this Skill is furthermore a declaration of the holder’s presence across all of space-time and thereby grants immunity against existential threats by way of time paradox or the instantaneous imposition of death.[1]
In the 7th Singularity of Fate/Grand Order, the 2nd Beast overcomes her restriction against landfall by use of Self-Modification -- altering her horns into wing-like appendages and taking flight. Upon the eradication of the Sea of Life within her immediate environs by the Divine Authority of Quetzalcoatl, she is able to spontaneously regenerate her domain by dispensing tides of the Black Mud from the base of her feet.
Self-Modification (EX Rank): Beast II can remold her Saint Graph through her Sea of Life. She can expand the scale of her standard Saint Graph (Femme Fatale), to a "Draconic Body" over 60 meters in height. In that form, Beast II is able to cancel any attacks ranked A++ or lower.[1]

Personal SkillsEdit

Kingu sJ0drd7

Kingu states that the Black Mud of the Sea of Life is the substance known as the Mud of the Grail.

Sea of Life (EX Rank): Tiamat's true Authority, it's the "Sea From Which Life Itself is Sprung". Because the sea circulates the True Ether that existed from the Genesis of the Earth, magical energy is infinitely supplied to Beast II while she's within the sea. 
The movement by which the Sea of Life extends its domain is referred to as the Chaos Tide. The substance of the Sea of Life is a Black mud pollutes that Saint Graphs and that fundamentally remakes any organism that enters unto the Sea as a "Child of Tiamat" that bears an arbitrary selection of the following skills: Environmental Modification, Environmental Fusion, and Unit Mitosis. Furthermore, the Children of Tiamat are imposed with a cellular-level Geis — a Nitrogenous Base Contract — that automatically renders them enemies of humanity.[1] Servants are no exception to the process. The weight of the black mud cannot be measured due to it being made of imaginary numbers, making its volume unlimited. In short, it is a four-dimensional pocket.[1]
In the 7th Singularity of Fate/Grand Order, Kingu refers to the Sea as the Primordial Organism and the Sea of Chaos -- further stating that, amongst practitioners of Magecraft, the Black Mud is the substance referred to as the Mud of the Grail.
Self-Seal (C+++ Rank): A chain of self-mutilation that ties down Beast II. Although Beast II hated her grief of being banished for “not being needed anymore” by the collective unconsciousness of humanity, the depths of her consciousness accepted that as something inevitable. Beast II, who has the role “mother” as her foundation, possesses a desire to function as a patron of humanity to the very end. This Self-Sealing is something that became that form.
Beast II constantly seals herself. This self-inflicted pain is equivalent to giving herself damage that deals 50% of Beast II’s current HP every turn. In the rare cases where Beast II emerges from the sea while losing her self-control, the seal admonishes her for this and the damage is raised to 90% of her HP instead for a moment. This is why she has +++ in this Skill.[2]
Nega Genesis

Nega-Genesis as depicted in the anime.

Nega-Genesis (A Rank): A Skill of the same variety as the 6th Beast's Nega-Messiah. A manifestation of a Conceptual Bounded Field (Genesis of the Earth) expressed within the proper continuity of the History of Man, consequently proffering a nullification against the Noble Phantasms of any Servants generated as an output of the above processes.[1][2] Specifically speaking, a barrier takes root against the Noble Phantasms of Servants with the attributesHuman” and “Star”.[2]
In the Anime it is referred to as an Authority that allows Beast II to create a new world by overwriting the current one, similar to a Reality Marble. The barrier expands and denies all established forms of life, those whose lives are over and have died, allowing it to instantly destroy Servants and even Divine Spirits like Ishtar while giving her space to create new life. As such, only the living are permitted to exist within the bounds of Nega-Genesis as their lives are not yet over. Only Ritsuka Fujimaru, new Laḫmu that are created within it, King Hassan and Fou are able to move in it without being destroyed.[16]
Monstrous Strength (A++ Rank): 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 giant when she makes the black mud into her body and manifests in her "Draconic body".[1][2] At the moment, only Tiamat and Kingprotea possesses this skill at EX rank.[17].

Other CapabilitiesEdit

  • Potnia Theron: Due to being worshipped as an Earth Mother Goddess, Tiamat had the power of creation that originated from the forgotten goddess of Çatalhöyük.[6] This Authority allowed Tiamat to function as a mobile creature factory that can "birth" millions of magical beasts from her true Authority, the Sea of Life. By using the endless magical energy supply, Tiamat could create millions of Lahmus in a few seconds, with each of them boasting power on par with the magical beast Ugallu. The most powerful creatures she created were the Bel Laḫmu, who possessed magical energy that surpassed that of a Demon God.
  • Regression to the Age of Gods: Tiamat is able to reproduce mysteries that predate Magic, by regressing to the Jurassic Age Tiamat was able to use the Sea of Life to remodel her Saint Graph and transform into her "Draconic body" form, which gave her the body of a God.[18]

Hypothesized CapabilitiesEdit

Paradox RestorationEdit

Romani Archaman and Gilgamesh hypothesize that Tiamat's existence as the Mother of Genesis renders as a Law of Nature the "fact" that she is "the first to be born into the World, and the last to die." That is to say, so long as another life exists within the same "World" as Tiamat, she may be incapable of dying.
Romani Archaman terms this capability "Paradox Restoration" -- and for the purpose of neutralizing the phenomenon, Gilgamesh plots to entrap Tiamat within the Underworld (冥界, Meikai?, lit. "World of Death") domain of Ereshkigal, making use of its nature as a "World" wherein the only "life" that is properly recognized to exist are those existences subjectively defined as "the Living"at Ereshkigal's whim. Furthermore, as the domain was in part originally created to restrain and confine rogue gods, the Sanctions of the Underworld exert a strong Anti-Divinity effect by default, and would therefore hypothetically weaken Tiamat.[5]
In practice, however, it is unclear that Paradox Restoration is indeed one of Tiamat's actual capabilities, or whether the actions taken against her were in fact effective in neutralizing the phenomenon.


Creation and ConceptionEdit

Kotetsu Yamanaka is the character illustrator for Tiamat.[1][2] Kinoko Nasu is the scenario writer for her character.[2]

It is a digression, but Tiamat was taken into consideration as a boss of a raid event when planning “Fate/Grand Order” in 2014. She is an anthropomorphism of the sea, someone similar to a generator that produces powerful Magical Beasts, and she was depicted as an unequalled beautiful woman that dissolves into the chaotic mud. During the moment Beast II appears, “Fate/Grand Order’s” image… becomes a fun Starship Troopers. It is also a service character that makes a homage to Dark Sakura of “Fate/stay night”. Revising that design is for some reason, two times more appealing, as long as you can see “Ah, it is a genealogy of that Dark Sakura.[2]

Comment from IllustratorEdit

"I joined together rivers/harvests and destruction (clear streams and sludge) growing wild as in the color image (of the black + red stripes) of Dark Sakura. I aimed at a simple silhouette of a little girl with gigantic horns + hiding her breasts.

Monster Form: For the MAP plan and on the occasion of expressing her parts, I crammed as many details of gigantic structures in order to potentially put them for another use. (I was thinking something like walking on a road above her horns.)"[2]
