Hagoromo Ōtsutsuki

, known to the world at large as the, was a legendary god-like figure who founded the arts of ninjutsu and created the ninja world. He was the son of Princess Kaguya Ōtsutsuki‎‎ and the first human to be born with chakra. He defeated the Ten-Tails in battle and sealed the beast within his own body, thus becoming the very first jinchūriki in history.

Background
Hagoromo was born as one of two children to Kaguya Ōtsutsuki‎‎, a princess who ate the forbidden fruit of the Shinju that appeared once a millennium in an effort to gain god-like abilities to put an end to the constant wars during that era. As a result, Hagoromo was born with the ability to manipulate the same type of powerful chakra as his mother. The Shinju, furious with Kaguya's actions, was determined to get its chakra back, which caused the tree to assume a monstrous form of what many christened as the "Ten-Tails".

The Ten-Tails rampaged throughout the lands until Hagoromo, alongside his brother, managed to defeat the beast by becoming its jinchūriki, and became revered as a god for the virtue of his victory. According to Jiraiya, with his knowledge of the concept of chakra, the Sage travelled across the land, spreading his ideals and religion, the, which eventually became the ability known as ninjutsu. His great deeds and ultimate desire to bring peace to the war-torn world made him widely known as the. Knowing that his death would unleash the Ten-Tails back into the world to continue its rampage, Hagoromo separated the monster's chakra from its body before using Chibaku Tensei to seal the husk in what would become the moon.

Hagoromo's ultimate wish was to establish peace across the world, but it was a goal that would never be achieved in a single lifetime. Knowing this, he chose to entrust his dream and legacy to his two sons, and began to teach them ninshū. The older son, Indra, was acknowledged by Hagoromo as a true prodigy, who quickly began to revel in his natural prowess, and became very solitary. The younger son, Ashura, proved to be the exact opposite, having shown no special abilities or natural talent, but he pushed on through his limitations, growing stronger and more mature because of his struggles and making friends along the way. Hagoromo acknowledged Ashura's chosen path, agreeing that love and cooperation were the true key to peace. From there, he used his Creation of All Things ability to divide the Ten-Tails' chakra into nine fragments that are each given a physical form and name. Some time after their creation, the young tailed beasts were told that they were all still linked to one another despite being separate entities. Hagoromo also told them that would eventually become one again, yet not as they originally were, and that one shall appear at that time to show them what true power is.

On his deathbed, Hagoromo chose Ashura to be his successor, but Indra, overcome by bitterness and envy, fought against his brother, beginning a war between them. Their feud has continued on through their descendants: the Senju clan and the Uchiha clan.

Hagoromo would leave behind a tablet for his descendants, detailing the history of his struggle with the Ten-Tails. Only those who possess the Rinnegan can fully decipher the contents of the tablet, while a reader with other dōjutsu such as the Sharingan can still partially interpret the information.

Personality
Hagoromo was a man who sought peace by spreading his wisdom across the world. He was exceptionally wise, as he was able to bring about a great change to the world by simply disseminating the principles of chakra and his religion. He also seemed to care a great deal for the tailed beasts when they were still with him; he gave them each a name as a sign of their individuality, and told them that no matter how far apart they grew, they would always be together, and would someday be led down the right path. In return, the tailed beasts showed respect and adoration for the Sage. Kurama even shed a tear at the thought of his imminent passing, suggesting that the beasts might even have viewed him as a sort of father-figure. Upon meeting Naruto, Hagoromo showed himself a very patient and composed individual, not being affected by Naruto's bursts of anger. He also is very stern to his teachings be recognized as "ninshuu" as "ninjutsu" was created for combat unlike ninshuu's pursuit of peace. He was a very intelligent man, able to methodically learn new forms of study including language and culture.

Appearance
Only seen entirely in his elderly age, Hagoromo had a long beard and short light greyish-coloured shaggy hair that spiked up in the front with two distinctive parts of his hair resembling horns and a chin-length braid hanging in front of his right ear. Hagoromo had pronounced eyebrow ridges with small horn protrusions above them. He also had a Rinnegan-like marking on his forehead. He wore a white full-length cloak (haori) with a high collar, revealing his necklace with six red magatama. These symbols were later mimicked by Nagato's Deva Path, and the seal around the neck of Naruto Uzumaki's and Minato Namikaze's Nine-Tails Chakra Modes and Tailed Beast Modes. On the back of his cloak was a reflection of a seal which had the Rinnegan with nine magatama (both red in the anime) in three rows beneath it, much like the seal which appeared on Obito and Madara Uchiha's backs after they became the Ten-Tails' jinchūriki

Abilities
Though not a great deal is known about all the skills Hagoromo possessed, he is widely accepted to be the most powerful figure in history, having single-handedly defeated the Ten-Tails: a being that was revered as a god, causing the Sage himself to be seen as a god. Hagoromo was also revered as the man to first understand the very nature of chakra itself. This wisdom, combined with his kekkei genkai, the Rinnegan, allowed Hagoromo to create the first modern ninjutsu. With such powers at his disposal, Hagoromo obtained a great following, as men and women from across the world strove to learn from his teachings.

Jinchūriki Transformation
Hagoromo developed the first technique capable of sealing a tailed beast inside a human body, making himself the very first jinchūriki in history. Having the Ten-Tails' great power contained within him, Hagoromo developed immeasurable power and chakra that far surpassed all others, allowing him to be renowned for possessing the Treasured Tools of the Sage of the Six Paths, which are tools that require a vast reservoir of chakra and would quickly kill any normal human in order to be used. Even on his deathbed, Hagoromo was able to employ his Chibaku Tensei technique on a massive scale and use that chakra to create the moon to seal the body of the Ten-Tails within it, a clear testament to his incredible power. His god-like abilites were later shown to even transcend time itself, able to continue observing the world and meet with people long after his death.

Ninjutsu
Hagoromo is revered as one of the most legendary figures in the ninja world, powerful enough to create the moon using Chibaku Tensei, while on his deathbed. Using fūinjutsu he was able to first seal the Ten-Tails into his own body, and was later able to seal it into the moon when his life came to an end.

Yin–Yang Release
By using the Yin chakra, that comes from the spiritual energy, and the Yang chakra, that comes from the physical energy, he had the ability to create form from nothingness with a mere thought to bring it to life. Hagoromo created the nine tailed beasts from the Ten-Tails' chakra by using this ability.

Bukijutsu
Hagoromo was shown carrying two objects. One was what appeared to be a katana, implying that he was skilled in kenjutsu, whilst the other was a shakujō — a Buddhist ringed staff which is meant to be used in prayer.

Hagoromo also made use of a holy sword known as the Sword of Nunoboko, which he reportedly used to create the world.

Treasured Tools
Hagoromo wielded unique tools which became known as the Treasured Tools of the Sage of the Six Paths, each of which possess a unique and powerful ability. The five treasures are: the Bashōsen, Benihisago, Kōkinjō, Shichiseiken, and the Kohaku no Jōhei. By combining the Benihisago, Kōkinjō, and Shichiseiken, Hagoromo could capture the word soul of his victims, and then draw them into the gourd to seal them away. With the Bashōsen, he could generate any of the five basic elements. The Kohaku no Jōhei allowed him to seal anyone without the elaborate procedures used for the Benihisago.

Rinnegan
Hagoromo was believed to have been the only shinobi to have fully mastered the Rinnegan, and also learned to control all five types of nature chakra. As a wielder of the Rinnegan, he also wielded all the abilities of the Six Paths Technique.

Return of Madara arc
After the Yin half of Kurama was sealed inside of Naruto Uzumaki, the legendary sage met within Naruto's mind to speak with him, noting that he felt drawn to Naruto. After the young shinobi grows angry from Hagoromo's philosophical speech, Hagoromo gets to the matter at hand. He begins to explain his family history to Naruto, also noting that Naruto is in fact the reincarnation of the sage's younger son Ashura.

Legacy
It is impossible to overestimate Hagoromo's effect on the course of the ninja world's development. As the first true ninja, he created the ninja world, revolutionised it, and left it forever changed. As his disciples grew continuously greater in number, it led to the creation of ninja clans, and later, ninja villages.

As time passed, Hagoromo ultimately faded into legend. His bloodline was divided into the descendants of his two children, which would eventually form the Senju clan — and through distant relations the Uzumaki clan — and the Uchiha clan. As a result of Madara Uchiha acquiring and integrating Senju DNA into his body, the Rinnegan would later resurface. Though he noted nothing happened initially after the DNA integration, when he neared the end of his natural lifespan, the dōjutsu finally awakened. With that, Madara Uchiha managed to undo Hagoromo's seal on the vessel of the Ten-Tails by summoning it from the moon and formulated the Eye of the Moon Plan to become the Ten-Tails' new jinchūriki.

Because Nagato, a pupil of Jiraiya's, manifested the Rinnegan, the latter suspected Nagato to be the reincarnation of the Sage himself. In reality, Madara secretly transplanted his own Rinnegan to the boy, without his knowledge. Nagato, as a descendant of the Senju-related Uzumaki clan, was the perfect host for the dōjutsu; however, Nagato himself noted that his own power would have paled in comparison to the Sage's. Others, including Kakashi Hatake, noted that the Rinnegan was viewed merely as a mutation. Kurama and Son Gokū's recognition of Hagoromo (and the tailed beasts' apparent status as the only survivors from Hagoromo's lifetime), lends credibility to his existence.

Before he died, Hagoromo told the young tailed beasts that someone would come and lead them on the right path. The tailed beasts would all later come to agree that this person is Naruto Uzumaki.

Trivia

 * literally means 'feather mantle' and is a reference to The Tale of the Bamboo Cutter, in which Princess Kaguya is given a hagoromo to wear upon her return to the moon. The surname roughly means 'big bamboo tree' and is derived from an obscure passage in the second volume of the Kojiki about the genealogies of Emperor Suinin, eleventh emperor of Japan, which states that he had a consort named, the daughter of a king named ; tradition holds that these individuals served as the basis for Princess Kaguya and the old bamboo cutter in the aforementioned tale.
 * The horn-like tufts of Hagoromo's hair may in fact symbolise rabbit ears, representing his connection to the moon by evoking the moon rabbit; pop culture depictions of Princess Kaguya and the moon-folk often incorporate features like rabbit ears for this reason.
 * The necklace that Hagoromo wore might be a reference to the Yasakani Jewel; a legendary magatama necklace that is part of the Japanese Imperial Regalia, together with the Kusanagi Sword and the Yata Mirror.
 * Hagoromo shares the same nickname with both the First and Third Hokage, who were all known as the.
 * Due to the Gold and Silver Brothers' ability to assimilate Kurama's chakra by eating some of its flesh, the Fourth Raikage suspected them to be distantly related to Hagoromo.
