Hamura Ōtsutsuki

was the son of Princess Kaguya Ōtsutsuki‎‎ and the brother of Hagoromo Ōtsutsuki. Alongside his brother, he was one of the first humans to be born with chakra.

Background
Kaguya Ōtsutsuki gave birth to two sons, the first humans to be born with chakra. To repent for their mother's sins, Hagoromo and Hamura fought and defeated the Ten-Tails, with Hagoromo becoming its jinchūriki. It is unknown what happened to Hamura after this.

Appearance
Hamura was a long-haired man with a neck-length braid hanging in front of his right ear. He also inherited horn-like protrusions on his forehead from his mother.

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.

Abilities
One of the most powerful figures in history, he was able to defeat the Ten-Tails in battle together with his brother. In battle he carried a staff and a sword which he was presumably skilled at wielding. He was also noted to have inherited his mother's powerful chakra.

Byakugan
Hamura also inherited the Byakugan from his mother. Possessing it granted him 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 and, if skilled enough, the 361 tenketsu along the pathway.

Trivia

 * As the inheritor of his mother's Byakugan, it is highly likely that he is the ancestor of the modern day Hyūga Clan.
