Ōtsutsuki Clan

The is a clan originating from another world, having arrived to the Earth about 1,000 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. Members of this clan notably have unusual anatomy such as horns and pale grey skin. They also seem adapted to living in otherwise uninhabitable environments such as the Moon.

History
In time distant, 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 unrivaled power. Seen as a deity by people and called the, Kaguya settled down amongst them, as she would eventually get pregnant and bear twin sons. However, Kaguya had grown despotic, the power having clouded her judgment, resorting to control mankind by force, something which would change her public image of a benevolent goddess into that of a. In a fit of jealousy that her children had inherited her chakra, Kaguya merged with the Shinju to turn against her own sons in a form of the monstrous Ten-Tails. After a fierce battle, with Hagoromo and Hamura standing victorious, the Tailed Beasts were made from her chakra, with her body sealed into Hagoromo's body. Later when Hagoromo divided the Ten-Tails' chakra into the tailed beasts and sealed its empty shell into the Moon, Hamura succeeding 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 the Shinju).

One millennium later, Toneri Ōtsutsuki, a direct descendant of the 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, specifically targeting Hinata Hyūga for unknown reasons.
