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. For unknown reasons, he doesn't seem to appear in the history or mythology of the shinobi world like his brother. Even Madara, with his rich knowledge of the origins of the shinobi world, was seemingly entirely ignorant of Hamura's existence.

Appearance
Hamura was a long-haired man who wore a light, full-length haori with 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.
