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.

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 they later divided into numerous clans over time.

History
In distant time, mankind fought countless battles, leaving the earth 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. Princess Kaguya, leader of the clan, would later consume the fruit to transcend and bring peace using her unrivalled power. Seen as a deity by humanity, Kaguya settled down amongst them, as she would eventually get pregnant and bear twin sons. However, Kaguya 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. In a fit of jealousy that her chakra had dispersed into her children, 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 intent to make her his bride and repopulate the Earth after its destruction.

Abilities
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.

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, 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. 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. The pinnacle of the clan's abilities of fūinjutsu is, by combining their knowledge with the knowledge of juinjutsu, they make an unnamed sealing technique that was used for protecting the main content of the Tenseigan and according to Hinata, the technique making it untouchable except by those with the "undiluted chakra of Hamura".

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 and Indra chakras and souls would also continuously reincarnate into their descendants over the millennium.
