Hagoromo Ōtsutsuki

, known to Earth's population at large as the, was a legendary godlike figure who is regarded as the ancestor of shinobi, for his act of founding ninshū which led to the creation of the ninja world. He was the son of Princess Kaguya‎‎ and alongside his fraternal twin brother, Hamura, were the first to be born with the same powerful chakra as their mother. Together, he and his brother defeated their mother, who had become the terrifying Ten-Tails, in battle and sealed the powerful beast within himself, thus making Hagoromo the first jinchūriki.

Background
Alongside Hamura, Hagoromo, the elder twin brother, was born as one of the two children to Kaguya‎‎, a princess who ate the forbidden Chakra Fruit of the God Tree that appeared once a millennium in an effort to gain divine abilities, which she used 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. Angered by the fact that her chakra had been spread to others, Kaguya merged with the God Tree into the Ten-Tails, which attempted to reclaim her chakra.

The Ten-Tails rampaged throughout the lands until Hagoromo and his younger twin brother managed to defeat the beast, with Hagoromo becoming its jinchūriki, causing him to be revered as a god for the virtue of his victory. Researching his mother's technique, Hagoromo was able to free the world from her Infinite Tsukuyomi. Going by the Sage of Six Paths after entering priesthood, he travelled across the land giving chakra to every one in the world, spreading his ideals and religion of ninshū in the process. His great deeds and ultimate desire to bring peace to the war-torn world made him widely known as the.

At some point in his life, Hagoromo suffered an unknown illness that was damaging his chakra pathway system from his time as a jinchūriki. After years of suffering and searching for a cure, he found his way to the Land of Redaku where he met Janmāru-Tataru. One night, meteor passed overhead, which the Sage caught and cut in two and one of the halves immediately dissolved into dust, which were dubbed "polar particles". The dust enveloped the Sage and healed his body. Hagoromo separated and hid the remaining particles into two groups

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, Asura, 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 with others along the way. Hagoromo acknowledged Asura's chosen path, agreeing that love and cooperation were the true keys to peace.

Inspired by his younger son, Hagoromo separated the Ten-Tails' chakra within his body and used his Creation of All Things Technique to divide it into nine separated bodies, creating the tailed beasts and giving each a name. As a result of extracting them all at once, Hagoromo was left weakened and incapacitated for several months, though the powerful life force of the Ten-Tails' husk kept him alive. Sometime 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 they 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. In the anime, it was shown that before his death, the Sage and his followers built temples in nine different regions of the world where the tailed beasts could live and be protected. Hagoromo eventually sealed the husk of the Ten-Tails within the moon. On his deathbed, he chose Asura to be his successor and entrusted him with his power, but Indra, overcome by bitterness and envy as well as being encouraged and manipulated by Black Zetsu, a manifestation of Kaguya's will, fought against his brother, beginning a war between them that would continue through their descendants.

Suspecting that Indra or one of his reincarnations would eventually attempt to take Asura's power for themselves, Hagoromo left behind a tablet detailing his history in an attempt to make them reconsider. 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. However, unknown to him, Black Zetsu, a manifestation of his mother's will, had altered the contents of his tablet so he could manipulate Indra's descendants, the Uchiha clan, through the ages into resurrecting Kaguya and initiating the Infinite Tsukuyomi anew. Even though Hagoromo died and his body was destroyed, his chakra and consciousness remained and traversed the world throughout the centuries.

In the anime's telling of events, well into their adolescence, Hagoromo and his brother lived in ignorance of their mother's true amoral nature. While their homeland continued to prosper, people would periodically disappear for a sacred Ritual of the God Tree. One day, the brothers were approached by Gamamaru, who revealed to them that beyond the peak of the nearby mountains lied the truth of the ritual. While initially ignoring the toad's words, Hagoromo grew distressed when a local girl he cared for named Haori became part of the ritual. When the brothers confronted their mother about ending the rituals, Kaguya dismissed their concern, simply saying it was necessary for "the others' arrival". Finally deciding to investigate, the two brothers were horrified to learn that the missing citizens were sacrificed to the God Tree. This especially hurt Hagoromo, and he awakened the Sharingan in his grief. Wishing to learn more, the brothers sought out Gamamaru. He revealed to them their mother's history of coming to Earth and using the God Tree's fruit to gain great power and enslave much of the land using Infinite Tsukuyomi, including their father. Deciding that they needed more power to confront Kaguya should she turn hostile, Hagoromo began training under Gamamaru in senjutsu. While Hagoromo quickly improved in this art, Kaguya soon caught on to her sons' scheme.

After Hagoromo completed his training under the Toad Sage, he returned to confront Kaguya, but not before being presented by Gamamaru with a special seal tag instilled with great sage power refined over the centuries. Once approaching Kaguya, the mother and son made their respective views known. As Hagoromo tried to reason with Kaguya, his words fell on deaf ears, as Kaguya deemed Hagoromo as ungrateful. She then had Hamura, whom she brainwashed, attack Hagoromo. Unable to reason with Hamura, Hagoromo was left with no choice but to strike down his beloved brother, which awakened his Mangekyō Sharingan and Rinnegan. Deciding to use Gamamaru's one-use gift, Hagoromo placed the seal tag on Hamura and healed him.

Angered by the fact that her chakra had been used against her, Kaguya wills the God Tree to transform into the Ten-Tails, which attempted to reclaim her chakra for her. Hagoromo and Hamura fought both their mother and the Ten-Tails in a battle that lasts for months, decimating the land in the process, until they were able to defeat them both by sealing Kaguya, and Hagoromo split the Ten-Tails' chakra into the nine tailed beasts. Later, Hagoromo was able to free the world from Kaguya's Infinite Tsukuyomi. While Hamura decided to stay on the moon to keep watch of their mother, Hagoromo chose to travel the earth to find proper dwellings for the tailed beasts and repent for the damage he caused the world from his fight against Kaguya. Before leaving, Gamamaru told Hagoromo a prophecy he had about a mischievous blue-eyed child who would one day connect with the tailed beasts and bring about a miracle.

Afterwards, Hagoromo eventually returned to his home village to act as the centre for the teachings of ninshū. He also fell in love and married a woman with whom had two children, Indra and Asura. During the second pregnancy, there were complications as Hagoromo's wife passed not long after giving birth to her second child. Hagoromo later began instructing his sons in Ninshū. The older son, Indra, was acknowledged by Hagoromo as a true prodigy, quickly began to revel in his natural prowess and became very solitary, unaware that much of this came from the subtle manipulations of Black Zetsu. The younger son, Asura, 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 with others along the way. Finally deciding the time had come to chose a successor to Ninshū, Hagoromo sent each on his sons on a different mission of restoration for a struggling land that was ravaged by the battle against Kaguya to test their capacities. Indra quickly returning after completing his while Asura took much longer. Deciding to wait for his younger son's return before making his decision, he was told the nature of how Indra completed his mission by Gamamaru. After a year went by since the missions were given, Asura completed his mission, but also returned with many people from the village, who were inspired by Asura and even learned Ninshū from him, having helped him complete his mission.

With Asura and Indra present, Hagoromo decided to choose his successor in Ninshū. Much to everyone's surprise, Hagoromo chose Asura. This greatly angered and confused Indra, who thought he was worthy of becoming the successor, and he stormed out into the wilderness. Later on, Hagoromo explained to Asura why he chose him as his successor and asked Asura to take care of the world with Indra, and Hagoromo gave Asura his power. Subsequently, Indra in a fit of rage attacked Hagoromo, Asura and the rest of the villagers with his Susanoo and newly acquired Mangekyō Sharingan, with his explanation as to how he obtained the dōjutsu drawing Hagoromo's disgust. Hagoromo and the rest of the villagers transferred their chakra to Asura to help him take on Indra, forcing the elder brother to flee.

As Hagoromo was nearing death and laying on his deathbed, Indra appeared to his father after years of disappearance and explained his ambition to take down ninshū. Hagoromo later relays this information to Asura and his family, entrusting his younger son with his final wish before dying.

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 admiration 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. His compassion and desire for peace was so great that even after learning of Kaguya's amoral actions, which included the death of Hagoromo's crush Haori, Hagoromo never succumbed to his grief and rage, despite it also awakening his Sharingan. Instead, he hoped to settle the matters with words rather than violence. Even more, despite rebelling against Kaguya, he still loved and respected her, constantly referring to her as "Mother" even when acknowledging how evil she became.

In the anime, Hagoromo's personality remained mostly the same in his youth, apart from the periodic immaturity that comes with adolescence. One example was when he gloated Kaguya's attempt to turn Hamura against him not only backfired, but also allowed him to awaken his Mangekyō Sharingan and Rinnegan.

Upon meeting Naruto, Hagoromo showed himself to be a very patient and composed individual, being unaffected by Naruto's outbursts. He was a very intelligent man, as even from a young age, he was able to clearly see through the demeanour and intentions of others. Very methodically, he could learn new forms of study including language and culture, able to seamlessly change his speech patterns and dialect to be better understood by people from a different era. He was also very stern about his teachings being recognised as "ninshū", noting that "ninjutsu" was created for combat unlike ninshū's pursuit of peace, and gripped his staff rather tightly when Naruto failed to distinguish the difference between the two. At the same time, Hagoromo was a very modest man, openly admitting that change is inevitable and one can only hope to prepare themselves for it. Likewise, he was open and truthful about his personal mistakes and shames as a father and leader. Despite his deified status, he also believed that no one should have more power than any other because there is a strong chance that the person will become arrogant and desire even greater power. After defeating his mother, Hagoromo made a personal choice to avoid using his inhuman powers whenever possible, both as a means to atone for the damage he caused the land and to better connect with normal people, feeling a certain pride and joy at accomplishing his tasks with normal effort.

After trying to undo the rift he unintentionally created between his sons, and their respective present incarnations, he ultimately lamented that he was unable to repair the damage he caused; as such he put his trust in Naruto only. Hagoromo was also rather open minded, but also a curious individual. When Sasuke told Hagoromo about his drastic plans to revolutionise the world, Hagoromo still shared half his power with Sasuke to see how events would unfold differently.

Appearance
Hagoromo was a tall and pale-skinned man, who had deep wrinkles and a strong jawline in his elderly age. He had spiky, shoulder-length, pale brown hair, with a chin-length, braided lock hanging in front of his left ear. He also sported a goatee, which was short in his younger years and later tapered down to his waist in his old age. Hagoromo had a pair of horn-like protrusions extending from either side of his forehead and — in the anime — pupilless white eyes. He also had a red Rinnegan-like marking in the centre of his forehead referred to as his ; in the anime, this marking appeared when he first awakened his Mangekyō Sharingan and Rinnegan. Hagoromo wore a white, full-length kimono with a pattern of six black magatama around a high collar, beneath which, he wore a necklace which was also made up of six black magatama. On the back of his kimono was a larger, black Rinnegan marking with a pattern of nine magatama arranged in three rows of three beneath it.

Abilities
Hagoromo is widely accepted as the most powerful figure in history, second only to his mother, having defeated the Ten-Tails and seal away his mother alongside his brother, with Hamura acknowledging his older brother as the stronger of the twins. Hagoromo's might and exploits ultimately made him revered as a god. He obtained a great group of followers, as many across the world strove to learn from his teachings. His power even transcended time itself, becoming able to continue observing the world and interact with people long after his death.

Chakra and Physical Prowess
Born as a son of Kaguya, Hagoromo was blessed with remarkably powerful and equally large reserves of chakra, evident from how far his dōjutsu naturally advanced on its own containing the Yin–Yang Release. The first person born with chakra, he also became the first man on Earth to understand the very nature of chakra itself. With no prior training, he had an innate and immensely precise control over its power, not needing hand seals for his various feats and proved to be very versatile in its usage, such as transferring chakra to others. His reserves grew exponentially higher after becoming the first jinchūriki in history with the Ten-Tails' great power contained within him. His power was so great that centuries after his death, with his genes greatly diluted, his distant descendants, Kinkaku and Ginkaku, were able to obtain jinchūriki-like powers by consuming the meat of Kurama instead of dying, as another Kumogakure shinobi did when attempting the same.

Hagoromo was also shown to have impressive raw might. While peaceful, he demonstrated considerable hand-to-hand combat prowess, able to easily fend off his younger brother's brainwashed assault. He also possessed equally remarkable strength, able to effortlessly rip out full-grown trees from the ground.

Ninshū
Hagoromo's wisdom, combined with his kekkei mōra, allowed him to create the original form of ninjutsu, Ninshū. He invented Ninshū as a way to bring peace to a war-torn world, sharing chakra with others and then teaching them to connect together with everyone using their spiritual energies as a mean to understand feelings of one another. He could also use it as a means to heal seemingly any ailment in an individual. He intended for this creation to connect all humans and bring forth harmony, however, following his death, humans began using the newfound power they wielded to fight against each other, and widen the rift between them all instead, turning it into what became ninjutsu.

Nature Transformation
Hagoromo became the first person to master all five elemental nature transformations. In the anime, he was shown to use Lightning Release to demolish a gigantic rock and create a blade of lightning to impale his foes. He could also use Wind Release to produce air currents to cut through the God Tree's bindings. With his mastery of the Yin–Yang Release to such an extent, he was able to combine his Yang chakra, the essence of physical energy, with his Yin chakra, the essence of spiritual energy, to create form from nothingness with a mere thought to bring it to life, an ability that he used to create the Tailed Beasts from the Ten-Tails' chakra.

Fūinjutsu
In preparation for his battle with Kaguya, alongside Hamura, Hagoromo developed immense prowess in fūinjutsu. With his mastery of sealing techniques, he was able to first seal the Ten-Tails into his own body, and was later able to seal it away when his life came to an end. 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 imprison the body of the Ten-Tails within it, a clear testament to his incredible power. His mastery of this skill also allowed him to brand others with a portion of his powers.

Sharingan
In the anime, Hagoromo awakened the Sharingan after finding the corpse of his love interest Haori. Similar to his descendants — the Uchiha — he gained much greater powers of perception, able to clearly see through enemies' tactics to better counter them. Unique to him, his Sharingan first emerged fully mature with three tomoe in both eyes and could maintain usage of this power seemingly indefinitely and unhindered.

Mangekyō Sharingan
In the anime, when finding himself unable to stop his younger brother from attacking in his brainwashed state, Hagoromo was forced to fatally injure him, manifesting the Mangekyō Sharingan. Quickly mastering this new power while in battle, Hagoromo became able to use Susanoo in its Complete Body form to fight on par with Kaguya's Ten-Tails form, even able to deflect one of the Ten-Tails' Tailed Beast Ball. With the simultaneous awakening of the Rinnegan, Hagoromo appears able to access his Sharingan abilities even while the Rinnegan is activated and suffers no adverse effect from using this power such as physical strain or deteriorating sight.

Rinnegan
Hagoromo possessed a derived form of his mother's dōjutsu; the Rinnegan. In the anime, he manifested it simultaneously with his Mangekyō Sharingan. He was believed to have been the only person to have fully mastered the Rinnegan, and also learned to control all five types of chakra natures. As a wielder of the Rinnegan, Nagato openly admitted his power with the Rinnegan was nothing compared to Hagoromo's. The Rinnegan grants him the ability to use all of the abilities of the Six Paths Technique. With the Outer Path, he could summon souls from the Pure Land and also undo another person's use of the Impure World Reincarnation, releasing the souls from their vessels and sending them back to the Pure Land.

Senjutsu
With his immense reserves of chakra inherited from his mother, Hagoromo was very well-adjusted to learning senjutsu to enhance his abilities. In the anime, this was taught to him by Gamamaru in Mount Myōboku, and Hagoromo showed an innate talent for it, shocking Gamamaru with his ability to clearly sense the presence of Natural Energy before gaining any training as a Sage and mastering the art in an inconceivably short amount of time. Along with his powerful chakra and Rinnegan, he was able to develop the Six Paths Senjutsu. With this, he could perform feats such as flying and levitating freely.

Truth-Seeking Ball
With his Six Paths Senjutsu, Hagoromo also had the ability to manifest up to ten Truth-Seeking Balls at a time,  which are composed of the five basic nature transformations, Yin–Yang Release and the Six Paths Sage Chakra. He typically shaped one of the orbs into a dual-headed shakujō. One end has a ringed hoop, while the other end possesses a crescent shaped curve, representing the sun and moon respectively. With this malleable chakra, he can also form the holy sword known as the Sword of Nunoboko, which he reportedly used to shape the world.

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, another weapon that he was likely proficient with.

Treasured Tools
Hagoromo wielded unique tools which became known as the Treasured Tools of the Sage of 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. All five of the tools requires enormous amounts of chakra to use, which can easily kill an average person by exhaustion, though due to Hagoromo's massive reserves, he shows no trouble with this issue.

Birth of the Ten-Tails' Jinchūriki
After Yang-Kurama was extracted from 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 grew frustrated from Hagoromo's philosophical speech, Hagoromo gets to the matter at hand. He begins to explain his family history from his mother to his two sons, to Naruto, which lead him to reveal to the latter that he is in fact the transmigrant of his younger son Asura. Realising that Naruto had already realised this on some level, Hagoromo also went on to explain that similarly, Indra has repeatedly transmigrated his chakra into others; most recently, as Naruto correctly guessed, Indra's chakra is in possession of Sasuke Uchiha. Hagoromo explained that Indra's previous transmigrant, Madara, sought not only the Sage's power, but that of his mother's, having broken from the normal cycle of life. As the Sage asked Naruto to stop Madara, Naruto thanked him for his trust, though Hagoromo insisted that he deserved no praise after his failings as a father and leader as well as having let the world continue to follow the belief of power for peace. Naruto disagreed with Hagoromo being a failure. Gyūki, Shukaku, and Yin-Kurama agreed as they appeared inside Naruto's mind, having just been transferred inside Naruto's body from Obito. As the tailed beasts voiced their agreement to Naruto being the child of the prophecy, Hagoromo summoned the other tailed beasts. Admitting to his mistake of solely trusting one son and ignoring the other, Hagoromo entrusted Naruto to help reshape the world for the better. He then asked Naruto what his goal was after the war ended. Simultaneously elsewhere, Hagoromo met with Sasuke, telling him the same story and asking him the same question. Accepting the respective answers of his reincarnated children, Hagoromo gives divides his power and chakra and bestows it evenly between the two rivals/friends, ensuring he did not repeat the mistake of only entrusting the task to just one. This also blessed the Naruto and Sasuke with awakening the Six Paths Sage Mode and the Rinnegan respectively.

Kaguya Ōtsutsuki Strikes
Later on, after Hashirama placed his hand on half of Madara's body, Hagoromo emerges from it in front of the reanimated Hokage, recognising Hashirama as Asura's previous transmigrant. Hagoromo then explains the current situation to the Hokage, and in the anime revealed the full history of his life. Telling them of a powerful summoning technique that he is unable to perform now as he gave nearly all his power to Sasuke and Naruto, he instead gives instructions to the Hokage.

After sensing his mother had finally been sealed by Naruto and Sasuke, the Yin and Yang marks he gave them reappearing on his own hands, he called the spirits of the deceased Kage to aid him in performing a Summoning Technique to bring Team 7, the tailed beasts, and Madara back from Kaguya's Dimension. Afterwards, he thanks Naruto and Sasuke for saving the world. Hagoromo then thanks Kakashi for effectively leading his students against Kaguya, who humbly says they did most of the work. Sasuke, noticing Madara was still alive, goes to finish him, only for Hagoromo to stop him, saying that having the tailed beasts removed from him without the assistance of the Demonic Statue of the Outer Path means he will soon die on his own. After everyone says their final words, Hagoromo then sends all the past Kage back to the afterlife.

As plans for the future were expressed, Hagoromo insisted to Yang-Kurama that it return to Naruto's side. Turning his attention to the present, Hagoromo began instructing Naruto and Sasuke on how to dispel Infinite Tsukuyomi. Before any such action even started, Sasuke made his own plans known. Planning to kill the current Kage and take control of the tailed beasts, he then swiftly placed the latter under his genjutsu and sealed them away in his own Chibaku Tensei. Sasuke then explained he wished to reshape the world as it should have been, doing so with revolution. Knowing already of Sasuke's intentions from their last talk, Hagoromo was saddened to see despite his efforts to make things right with his children in a new life, they still ended up fighting each other. Naruto however firmly said he would put an end to this sibling feud. Knowing his time left in this world was nearly up, Hagoromo chose to trust Naruto. Watching as Team Kakashi dissolved once more, he approached Kakashi as he tended to an unconscious Sakura. Citing that the past is there as a reminder, he expresses his confidence that Naruto would be able to transform Sasuke's hate into love. Hagoromo begins to disappear and he tells Kakashi to believe in them, because there was nothing more they could do.

Legacy
It is almost 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. However, despite his efforts of using ninshū to promote peace through the world, over time following his passing, people began to use chakra as means to get stronger and weaponised this power, deviating away from the true teachings of ninshū and ultimately formed what became ninjutsu.

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 the DNA of Hashirama Senju into his body, thereby fusing the chakras of Indra and Asura and creating Hagoromo's chakra, the Rinnegan would later resurface. Though he noted nothing happened initially after the DNA integration, when Madara neared the end of his natural lifespan, the dōjutsu finally awakened. With that, Madara 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, possessed the Rinnegan, the latter suspected Nagato to have been the reincarnation of the Sage himself. However, in reality, Madara had secretly transplanted his own Rinnegan into 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 and Ōnoki, noted that the Sage was a myth and the Rinnegan was viewed merely as a mutation. The tailed beasts' recognition of Hagoromo (and their apparent status as the only survivors from his lifetime), lended credibility to his existence. Centuries after Hagoromo died, Hagoromo's prophecy from Gamamaru about the world-changing boy who would unite the tailed beasts finally came true, as the tailed beasts themselves would all later come to agree that this person is Naruto Uzumaki, giving him their trust and a portion of their respective powers.

Aside from the well known Senju, Uchiha and Uzumaki clans, Hagoromo had some lesser-known descendants who were able to adapt to the Tailed Beasts powers, such as the Gold and Silver Brothers who were able eat Kurama's chakra meat and gain power from it instead of dying, or a certain individual whose body Kido Tsumiki and Magire used to help cultivate the Tailed Beast Drug.

Video Games
Hagoromo Ōtsutsuki makes his first video game appearance in the main story of Naruto Shippūden: Ultimate Ninja Storm 4 where he plays the role as the game's narrator. At the beginning of the game's story mode, the unseen Hagoromo presents the player with a scroll without a name which records the game's story. Upon completing the main story, Hagoromo decides that all there is left to do is to give the scroll a name and names it The Tale of Naruto Uzumaki. He plays his role as the narrator again in the Road to Boruto expansion for the game, presenting another scroll without a name to the player, but this time, he doesn't give the scroll a name at the end of the story. The reason for this is because, according to him, Boruto's path in life will keep going on for a very long time. Eventually, Boruto will look back on his path in life, and when he does, the story will get a name. Hagoromo concludes by telling the player that until then, this story will not have a name.

If the player is KO'd in story mode, Hagoromo will appear and will allow them to continue the battle, giving them the option of increasing either their attack or defence power for the remainder of the battle. However, if the player gets KO'd during the Kabuto vs Itachi battle, Itachi will appear instead of him.

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.
 * His horn-like appendages 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.
 * In the fourth databook, Hagoromo is called on one occasion. Although both "sennin" and "shinsen" can be translated as "sage", the latter is an archaic way to refer to supernatural beings and even gods.
 * 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.
 * Prior to his full appearance in the manga, the anime depicted Hagoromo with a different colour scheme: he had light-coloured skin and dull-brown hair, both the magatama around his neck and the markings on his back were red, and the top part of his shakujō was golden. This colour scheme was also used in Naruto: Colour Edition.
 * Despite using Truth-Seeking Balls in the manga, he is not listed as a user of this technique in the fourth databook.
