Ōtsutsuki Clan

The is an ancient clan originating from another world, having arrived to the Earth over a thousand years ago. Several members of this clan have heavily influenced both the shinobi and the world at large with their actions having shaped the world into what it is today. Some members of this clan have unusual anatomy such as horns, they also tend to have paler complexions. They are the progenitors of notable clans such as the Senju, Uzumaki, Uchiha, Hyūga, and Kaguya clans. They are also the originators of puppets.

In The Last: Naruto the Movie, it has been long thought that the clan itself is nearly extinct in name, but it's still extant through Hamura's line, with the sole member, Toneri Ōtsutsuki himself. However, the clan's bloodline status remained extant through Hamura and Hagoromo's descendants on Earth, although over time they have divided into numerous clans. In Boruto: Naruto the Movie, it is later revealed that there are still many distant descendant members of this clan that live scattered in numerous and various realms in the universe. However, aside from Momoshiki's and Kinshiki's death and after this point, the fate of the rest of the surviving distant descendants of this clan is unknown.

History
At some point in the past, the Ōtsutsuki left their home realm. The reason why they left is unknown, but presumably for seeking more power to strengthen themselves by making a panacea that will grant them unlimited supernatural powers, eternal youth, and immortality. By using their natural prowess (because chakra in that time is something that is never known by most living beings at that time, and the Ōtsutsuki tend to use the word "power" to describe it), they traveled to many realms in the universe throughout the ages. If they find an interesting place where the "power" could be obtained, they will stay there. It could explain the reason why they live scattered across the universe. Momoshiki also stated he had seen various interesting sentient beings, various interesting planets and places, and what and how the alien life is doing, with his own eyes, so he could actually compare them. This indicates there might actually be many of them and other alien beings out there.

Over a millennium ago, a wave of Ōtsutsuki led by Princess Kaguya landed on Earth, which in that time was a war-torn world where mankind fought countless battles, leaving the land soaked in blood. A tree would grow from the blood of the deceased, getting attention of the Ōtsutsuki clan, as it bore a fruit of great power. Kaguya, who longed for peace, would later consume the fruit and use her unrivaled power to end the conflicts. Seen as a deity by humanity, Kaguya settled down amongst them, as she would eventually get pregnant and bear twin sons. However, Kaguya, later changed to another personality caused by two factors. First, she became despotic, as the power having clouded her judgement, resorting to control mankind by force, something which would change her public image of a benevolent goddess into that of a demon. Second, she later discovered that two Ōtsutsuki descendants, Momoshiki and Kinshiki, were plotting to stealing her chakra for themselves. Driven insane in the preservation of her chakra, Kaguya converted the people trapped in the Infinite Tsukuyomi into White Zetsu soldiers, with the intent of fighting Momoshiki and Kinshiki should they ever make their move. In a fit of jealousy that her chakra had dispersed into her children, her power-hunger that soon corrupted her, and in paranoia of coming of the incoming Ōtsutsuki invaders, Kaguya merged with the Shinju to turn against her own sons in the form of the monstrous Ten-Tails. After the fierce battle, with Hagoromo and Hamura standing victorious, Hagoromo sealed her into himself, becoming the first jinchūriki. On his deathbed, the tailed beasts were made from her chakra, with her body sealed to form the core of a celestial body that would be known as the moon. Hamura, succeeding to the leadership of the clan, later departed along with the rest of the Ōtsutsuki to the moon in order to guard their late princess (something they weren't aware of, thinking it to be only the Shinju), while Hagoromo would stay in order to spread chakra to humanity and teach them the concept of Ninshū.

The clan was separated into two parts, the Main family and the Branch family; the clan inhabited the moon for a thousand years, and the descendants of Hamura sealed their eyes within the Tenseigan, a giant orb accumulating tremendous power. The Branch family misinterprets Hamura's celestial decree, if they determined that mankind were using their chakra for evil after a millennium, they would unleash that power upon them. Clashing over differing ideals, the clan divided itself between the main and branch families and warred with each other, driving the clan to the brink of extinction.

One millennium later, Toneri Ōtsutsuki, a direct descendant of Hamura and sole survivor of the otherwise extinct clan, would return to undo what his ancestors had made, planning to destroy humanity by having the moon collide with the earth, as a punishment for humans abusing chakra for militant purposes, and also specifically targeting Hinata Hyūga with the intent to make her his wife and have her help him repopulate the Earth after its destruction.

A little over a decade later after Toneri's attack, two distant descendants of the Ōtsutsuki clan, Momoshiki and Kinshiki would arrive on earth in search of the tailed beasts, seeking to recreate the fabled Chakra Fruit and cultivate it into cinnebar panacea, which would granting them eternal youth and even stronger supernatural powers. After abducting Naruto and fighting him, his son and Sasuke in another dimension, they would ultimately be defeated by the three shinobi's combined effort.

Abilities
It is very difficult to define the limits of their natural prowess as they are revealed to be unclear and far beyond human understanding. In the ages where chakra was an unknown concept by most of creations at that time, they somehow were able and displayed ability to travel many realms throughout the ages using their natural prowess. It's also shown if the remaining "purest" members of this clan, like Momoshiki and Kinshiki, have very unique attributes and archetype than humans and even other Ōtsutsuki clan's members, indicating the clan members somewhat retained both nigh-omnipotence and nigh-omniscience attributes, even a being like Kaguya feared both of them and forced her to amass countless White Zetsu Army in past in order to fend off against them and attempted to stop their attempt to steal her chakra. Another interested trait of the clan is, the very extreme longevity which they possessed, like Momoshiki and Kinshiki displayed. They were alive even after centuries had passed and displayed no significant aging process. Some of notable clan members also tend to display certain a mix of power hunger and god-like complex, although most of the clan members not displayed it.

Aside their natural prowess, as one of the original people to have received chakra, the strength of it is extremely powerful and in massive quantities compared to most shinobi. The kekkei genkai, most importantly the three great dōjutsu originated in this clan with the Byakugan, Sharingan, and Rinnegan being wielded by members of the clan. Kaguya possesses a predecessor ability of the Shikotsumyaku. Most of the members are born with the Byakugan, which they would seal into the Tenseigan, the clan's ultimate weapon.

The "real" ability of this clan, as stated by Momoshiki, was making medicine. Their ambition was to make a panacea which would grant unlimited power, eternal youth, and immortality. Their ambition also led them on an exodus from their home realm and to travel from star to another star in order to harvest more power to create it. This resulted in members of the Ōtsutsuki clan being scattered across the universe.

As the originators of puppetry, they also have advanced knowledge in mechanical engineering, as they are capable of creating various types of puppets. Interestingly, instead of chakra threads, they directly control their puppets using the power of the energy vessel. The energy vessel allows for the puppets to also work independently in various tasks, making their puppet abilities somehow equivalent with real-life robots.

The clan appeared to be very knowledgeable in the art of fūinjutsu, even long time ago before the concept of chakra itself created, and they can make their own intricate and advanced sealing techniques. As shown by both Hagoromo and Hamura's capability to seal the Ten-Tails with Six Paths — Chibaku Tensei, a very powerful ancient sealing technique that even Hagoromo or Hamura with their own prowess in their youth were not able to perform it by themselves, so they ended up splitting it into two separated parts. Hagoromo eventually mastered it to the point where he can perform it by himself, but not in the mortal plane. The Six Paths Ten-Tails Coffin Seal was also likely created by Hagoromo at some unspecified time as the technique's description and instruction were inscribed on the Hagoromo's tablet which came to be possessed by the Uchiha clan. From Hagoromo's line, the clan's abilities in fūinjutsu apparently eventually passed to the Uzumaki clan. From Hamura's line, the clan also developed some form of sealing method for sealing their own Byakugan to the Tenseigan, although the reason why they did it was unknown. Another testament of the clan's abilities was an unnamed curse technique that was applied to the Tenseigan vessel and according to Hinata, made it impossible to destroy the vessel by anyone not part of Hamura Ōtsutsuki's lineage, instead draining them of their chakra.

The chakra of the clan members is also powerful enough to transcend time along with their soul and consciousness, even many years later after their deaths, as shown by Hamura - the last patriarch of the main family and the rest of his dead clansmen being able to meet with Hinata, to give her power and knowledge. Hagoromo was also able to temporarily materialise in the physical realm of the living, using his residual chakra in Madara's remains. His sons', Asura's and Indra's, chakras would also continuously reincarnate into their descendants over the millennium.
