Hamura Ōtsutsuki

was the son of Princess Kaguya Ōtsutsuki‎‎, the fraternal twin brother of Hagoromo Ōtsutsuki; both of whom were the first two born with the ability to wield chakra. Hamura was the ancestor and the founder of the shinobi of the moon.

Background
Hamura was born the younger of Kaguya Ōtsutsuki's twin sons, the first humans to be born with chakra. When Kaguya realised both Hamura and Hagoromo also had the ability to wield chakra, Kaguya — as the Ten-Tails — tried to forcibly reclaim her chakra out of rage and jealousy. Eventually, Hagoromo and Hamura succeeded in defeating and sealing her within Hagoromo. Some time later, Hagoromo created the tailed beasts and extracted the Ten-Tails' skeleton from his body and sealed it into the moon, resulting in his death. Before his brother's demise, Hamura and the rest of the clan departed to the moon, in order to guard his mother's sealed remains, though not before receiving instructions from his brother to wait for a full millennium and observe mankind. Hamura eventually died, and the clan dwindled until only Toneri Ōtsutsuki survived by the time a thousand years had passed.

Personality
Hamura was a man who believed in peace and freedom opting to seal away his own mother, ending her reign of terror. Also, he was very dutiful, as he remained on the moon to guard Kaguya's sealed body. Hamura even had a great deal of loyalty towards Hagoromo, wishing to protect the world his brother created, even for a thousand years after his own death.

Appearance
Hamura was a tall and pale-skinned man with hairless brow ridges and waist-length white hair. His bangs were short hung to left side of his face with a chin-length lock which hung from the right side of his face. He also inherited from his mother small horn-like protrusions on his forehead and inherited the renowned Byakugan in each of his eyes. He wore a light, full-length kimono with a pattern of six black magatama around a high collar and dark pants. He had his sword in its sheath strapped to his left hip. He also had a dark crescent-moon representing Yin mark in his left palm.

In his old age, his appearance was very frail, his ribcage was slightly visible, his brows became more prominent, and he had deep wrinkles in his face and his once white hair had turned grey. He wore a white kimono with a black wide collar ceremonial kimono, with a light green sash tied over his right shoulder.

Abilities
One of the most powerful figures in history, Hamura was able to defeat the Ten-Tails in battle together with his brother. During battle, Hamura wielded a sword with presumable proficiency as well as a shakujō. He was also noted to have inherited his mother's powerful chakra and wielded the Six Paths Yin Power in his left hand that he used in combination with Hagoromo's Six Paths Yang Power to seal the Ten-Tails into the core of the Chibaku Tensei. Like his brother, Hamura's chakra was also powerful enough to transcend time, even centuries after his death. Through this, Hamura was able to meet with Hinata and bestow upon her the power to destroy the energy vessel.

Byakugan
As a wielder of the Byakugan, Hamura had access to the standard abilities of the dōjutsu such as: a near 360° vision (with the exception of a small blind spot at the upper thoracic vertebrae), x-ray vision, and the ability to see the chakra pathway system amongst other abilities.

Tenseigan
At some point, Hamura had awoken the Tenseigan in his own eyes, and before his death, he sealed their power into the Energy Vessel. As a result, the branch family of Ōtsutsuki‎‎ clan would use as it as a weapon to annihilate the main branch and Toneri, who misinterpreted Hamura's celestial decree, would later use it to pull the moon down to Earth.

Truth-Seeking Ball
Hamura also had the ability to manifest Truth-Seeking Balls,   which are composed of the five elemental nature transformations and Yin–Yang Release. Positioned in a curved formation, he typically wielded a black shakujō. Later, in his older days, his Truth-Seeking Balls are floating away in crescent formation behind his right side back. Unlike other users that form a set amount of ten balls floating behind them, he only has five.

The Last: Naruto the Movie
An elderly Hamura, alongside his deceased clansmen, appeared before Hinata Hyūga to discuss how she, as the, was the only one capable of destroying the Energy Vessel, which was being used to control the moon by his descendant Toneri after misinterpreting his will. With that, he transferred his own power to Hinata to give her the ability to resist Toneri's chakra orb as well as the power to destroy the Energy Vessel.

Legacy
Hamura's descendants, the Ōtsutsuki clan, acquired the Byakugan, but they sealed their eyes in the Energy Vessel. The branch family of his descendants and the sole survivor of the Ōtsutsuki clan, Toneri Ōtsutsuki, misinterpret his celestial decree while trying to punish mankind for abusing chakra and using it to wage wars.
