Kaguya Ōtsutsuki

Princess is the mother of Hagoromo Ōtsutsuki and Hamura Ōtsutsuki, who consumed the fruit of the Shinju and became the progenitor of chakra, and part of the creation of the beast that would become known as the Ten-Tails.

Background
Kaguya is a princess who hails from an unknown distant land, and had lived long before the founding of the hidden villages, during an era of endless wars between mankind. Longing for peace, Kaguya decided that it was necessary for her to attain god-like powers in order to put an end to all conflicts. For this reason, she defied the taboo of consuming the fruit of the Shinju, becoming one with the holy tree's power. For her deed of single-handedly ending the wars, Kaguya was worshipped as the. As time passed, however, the power she held ultimately corrupted her, and Kaguya sought to prevent humanity from causing any further harm to the world by trapping them within the Infinite Tsukuyomi, and converted the victims that were assimilated by the Shinju into White Zetsu. This and the other horrifying acts Kaguya committed struck terror into the hearts of the then-powerless people around her, for which she would be feared as the.

Kaguya later gave birth to two sons: Hagoromo and Hamura, both of whom inherited the same powerful chakra she wielded and unique dōjutsu along with it. Angered at the power gained by her children, Kaguya and the Shinju melded into an entity that would later become known as the Ten-Tails with one singular goal: reclaim the chakra she felt was rightfully hers. The Ten-Tails rampaged throughout the lands until Kaguya's sons defeated, and sealed the beast and their mother away. Before her sons could completely seal her, Kaguya's will manifested in the form of Black Zetsu. This manifestation would soon begin its machination to revive Kaguya.

Her son Hagoromo would later teach humanity to use chakra as a way to connect to one another, rather than weaponising it as Kaguya had done before.

With the agenda of reviving its creator, Black Zetsu manipulated the Sage's sons Indra, and his descendants: the Uchiha clan, along with Asura's descendants: the Senju clan, all in an attempt to get one of them to awaken the Rinnegan. Madara Uchiha would eventually succeeded in doing so, and Black Zetsu began secretly manipulating world events to have Kaguya revived.

Personality
After obtaining the ability to manipulate powerful chakra from the Shinju's fruit, Kaguya developed both a god-complex and messiah-complex, believing that chakra rightfully belonged to her alone and that only she could protect and unite the world. Despite her initial desire for peace like her sons and grandsons, Kaguya opted to use her great and terrible power to submit everyone to her will. As Hagoromo noted, humanity around that time began to fear her as a demon. She uses the archaic pronoun when referring to herself — a sign of ancient nobility.

Kaguya also displays a degree of affection, as she appears to care very deeply about the world, viewing it as a nursery that she didn't want humanity damaging any further. Although she openly stated that she hated her own sons for their ability to wield chakra and created the Ten-Tails to get it back by force, she openly wept when looking at Naruto and Sasuke, who reminded her of them.

While her belief of chakra should belong to her alone made her somewhat obsessive in retrieving it from everyone else, she is willing to listen to Black Zetsu's suggestion on killing Naruto to prevent him and Sasuke from sealing her away, though she expressed reluctance that she must destroy a large reservoir of chakra to preserve her freedom.

Despite her sombreness, Kaguya can nonetheless be stunned by unexpected events, as one of Naruto's perverted ninjutsu caught her off-guard, allowing him to land a hit on her.

Appearance
A woman in possession of very delicate facial features, Kaguya also had an extremely long, sweeping light coloured hair that touched the ground. Most noticeable were two horn like protrusions which stuck out from her head — appendages inherited by both her sons. Kaguya possessed the Byakugan, and also had a third eye on the centre of her forehead that's eyelids parted vertically. Her eyebrows were cut very short — a symbol of nobility, and she wore a dark shade of lipstick on her lips and a dark shade of nail polish on her long fingernails. She wore the transitional high-collared hime-kimono which was adorned with intricate lines and tomoe running down the centre and edges of the gown.

Abilities
Having consumed the fruit of the Shinju, Kaguya achieved such unrivalled power that she was able to pacify the war-torn world all by herself, leading the people to worship her in fear. Hagoromo, being a legendary figure himself, praised his mother's might as superior to all others, including his own. Statements made by Naruto Uzumaki, and Sasuke Uchiha indicate that Kaguya possesses more chakra than both the Ten-Tails and its jinchūriki, Madara Uchiha. Black Zetsu claimed that Kaguya, rather than the Ten-Tails, is, in fact, the progenitor of all chakra.

As the progenitor of chakra, Black Zetsu states that Kaguya can also absorb any technique that she encounters. Much like the jinchūriki of the Ten-Tails, Kaguya displayed the ability to fly. In combat, she is able to materialise enormous chakra fists, easily surpassing the power of the chakra arms employed by jinchūriki. She is capable of destroying a Perfect Susanoo without much effort.

Kaguya has shown the ability to manipulate nature itself. One such instance she was seen manipulating lightning, causing a thunder storm. While in her dimensions, she has also shown the ability to meld with the world and control the substance within it, such as the ice and snow in her frozen mountainous dimension.

Kaguya is able to manifest her will, an ability that allows her to create life to serve on her behalf. Initially, she created the Ten-Tails in order to reclaim the chakra her two sons had inherited. Just prior to her sealing, Kaguya was able to create Black Zetsu, using the latter to revive her centuries afterward.

Kaguya is capable of very fast movement, displayed when she suddenly appearing before individuals in the blink of an eye. While not her specialty, Kaguya has shown a degree of unarmed combat skills, able to easily block several attacks from Naruto's omnidirectional shadow clone-assault. She can also use her extremely long hair as a makeshift weapon capturing and tossing foes around the battlefield or shooting it like senbon with enough ferocity to pierce even Sasuke's Susanoo. She is able to harden her hair to shield her from attacks. When making physical contact with an enemy, she is able to halt their movements while absorbing their chakra.

Dōjutsu
Kaguya is the only known wielder of all of the. Using these dōjutsu, she was able to quell the fighting in her era.

Byakugan
Kaguya wields the Byakugan in both eyes, granting her near 360° vision (with the presumed exception of a small blind spot at the upper thoracic vertebrae that all wielders possess), x-ray vision and the ability to see the chakra pathway system. Her sight with the Byakugan was also able to bypass the defence of Susanoo. In conjunction with her hair, Kaguya is able to see the individuals' vital points, accurately piercing them in order to immobilise them completely.

Rinnegan
Kaguya wields her Rinnegan as a third eye on her forehead, which is red in colour and contains several concentric circles and nine tomoe. Her third eye also grants her the Sharingan's powers, such as seeing the flow of chakra, casting and easily recognising genjutsu, heightened powers of perception as well as the ability to copy techniques. The eye once enabled, allowed Kaguya to cast the Infinite Tsukuyomi.

With her third eye, Kaguya is also able to instantaneously teleport herself and others around her to a different dimension, while simultaneously erasing the presence of their chakra. She is also able to instantly rewrite all of the aspects of this dimension, easily catching her opponents off-guard. Kakashi compares the seamless nature of this ability to the creation of genjutsu. Similarly, Kaguya is able to open and travel through rifts in space as a means of instantaneous travel.

Shikotsumyaku
Kaguya's shown the ability to manipulate and by extension weaponise her own bone structure, enabling her to have a vast array of battle options without any need to carry weapons on her body. With one such technique, she is able to launch her bones like a projectile, disintegrating whatever she impales.

Infinite Tsukuyomi Arc
After the Infinite Tsukuyomi was finally cast by Madara Uchiha, he attempted to finally tie up loose ends by eliminating Naruto Uzumaki, Sasuke Uchiha, Kakashi Hatake, and Sakura Haruno. When he proclaimed himself as the Saviour of the World, Black Zetsu — who had been standing behind Madara prior — impaled the elder Uchiha with his hand. Zetsu revealed that his will was Kaguya's own, before covering Madara's body with his own malleable mass. As Sasuke and Naruto attempted to intervene, they were captured by hair-like appendages while Madara continued to grow. He eventually stopped growing, actually shrinking down to a similar size that he was originally, but Madara was no longer there, as Kaguya had taken his place. She looked on at the surroundings, noticing Naruto and Sasuke and, more important, the marks on their hands before the hair-like appendages, now made up of her actual hair, threw them back to the ground. She activated her Byakugan, noticing that the two youths had similar chakra to her sons and Hagoromo's children, before coming to the conclusion that Hagoromo had bestowed the powers to them. Kakashi asked her about her motives, which led her to state that the world was her nursery and as such she wanted no more fighting to damage it any further. She then teleported Team Seven and Obito into an active volcano, telling them that she would have them disappear.

However, all five of them managed to avoid death. Seeing this Kaguya struck them once again with her hair, this time aiming with her Byakugan and firing needle-like strands at Sasuke, who was saved by Naruto whom had just discovered his ability to fly. Noticing this, and Naruto's power resembling that of her son, Kaguya grew enraged and clashed with Naruto while declaring all the chakra in the world should once again be hers. As she knocked Naruto back, Sasuke appeared above her and attempted to strike her with his Susanoo's sword.

The assault left Kaguya unscathed and she was able to rebuff Sasuke sending him reeling to where he almost fell into the lava, before teleporting behind Naruto and using one of his Truth-Seeking Balls as a platform for safety. Kaguya immediately entered a dimensional void and transported herself behind the duo, noticeably crying due to the resemblance they held to her own children, before forcing Black Zetsu over their bodies. Black Zetsu then began to tell the two youths the truth about past events, things that even Hagoromo was unaware of. He told them that Hagoromo and Hamura once sealed Kaguya using the same powers that Sasuke and Naruto inherited and that he had been manipulating the descendants of Asura and Indra for presumably all of time, attempting to get an Uchiha to awaken the Rinnegan and activate the Infinite Tsukuyomi so that the Ten-Tails — and subsequently, his mother, Kaguya — would be revived.

Kaguya, still crying, then stated she hated her two sons for what they did to her, causing Naruto to grow enraged, not understanding why Kaguya was so angry that her sons had gained powers like her own, before tearing the Black Zetsu off himself and Sasuke. To create an opening, Naruto convinced Sasuke to attack Kaguya with Amaterasu, which allowed him to get close to her and use his Sexy: Reverse Harem Technique. The technique was successful in distracting Kaguya long enough for Naruto to strike her, allowing Sasuke to teleport the two of them around her and begin the sealing. In that moment, Kaguya shifted them into a frozen kingdom, encasing herself and her foes in ice. Kaguya then created a portal to escape the ice, before Sasuke used his Blaze Release: Kagutsuchi to free himself and Naruto. At the behest of Black Zetsu, Kaguya created another portal to grab Sasuke, and then proceeded to teleport him to a desert landscape in order to eliminate them one at a time.

As Kaguya went to deal with Naruto, the crafty ninja began drawing aid from the tailed beasts within him, plowing through Kaguya's defensive and quickly overwhelming her with a massive army of shadow clones, calling it his own "personal dimension". The princess quickly retreats through her portal, to which Naruto quickly follows through, as does Obito along with Sakura and Naruto-clone. While the shadow clone quickly disperses, Black Zetsu is shocked that Naruto could follow them to the base world of Kaguya's various dimensions. While Kaguya is determined to "reclaim" the massive chakra within Naruto, Black Zetsu points out that Naruto is too dangerous and should just take the easier route of killing him. Dismayed in agreeing, Kaguya then launched a jagged bone barrage on Naruto that impales him and starts to disintegrate. Kaguya then returned to the normal dimension, only to find that Naruto's shadow clone army didn't disperse. She comes to realise that the body she killed was a well-disguised clone, and then sees that only the true Naruto, among the clones, possesses the Truth-Seeking Balls on his back.

Legacy
Despite Kaguya's meaningful attempts to bring forth peace, her methods only brought it about temporarily. It also inspired the people of Hagoromo's era to weaponise chakra for wars instead of using it for peace, which would include the tailed beasts being seen as nothing more than masses of powerful chakra to exploit and control. Before she was sealed away, she created Black Zetsu as a tool to facilitate her revival. Black Zetsu's actions throughout the history of the shinobi world included influencing the Uchiha clan for hundreds of years, tampering with the Naka Shrine stone monument.

Kaguya is the progenitor of the Uchiha, Hyūga, Senju, Uzumaki, and Kaguya clans, as she is the mother or grandmother of each clans' ancestor and originator of the Uchiha and Hyūga clan's dōjutsu kekkei genkai, the powerful chakra and life force of the Senju and Uzumaki clans, and the Kaguya clan's bone-manipulation kekkei genkai.

Eventually, Black Zetsu's efforts swayed Madara Uchiha to carry out the Eye of the Moon Plan, and creating Akatsuki as a project to prepare the Infinite Tsukuyomi, which led to the Fourth Shinobi World War. Madara would later succeed in casting the Infinite Tsukuyomi upon the entire world thinking he had accomplished his goal when in reality he facilitated the revival of Kaguya. Finally, Black Zetsu manifested his will into Madara, using him as a vessel to once again bring Kaguya back into the living world.
