Kaguya Ootsutsuki

Princess Kaguya Ōtsutsuki is the former matriarch of the Ootsutsuki Clan and mother of Hagoromo and Hamura. Long before the founding of the hidden villages, during an era of endless war, Kaguya consumed the fruit of the infected God Tree and became the first wielder of chakra on Earth, before later merging with the tree to become the Ten-Tails.

A millennium ago, Kaguya arrived on Earth with a portion of the clan in search for the fruit of the God Tree, which chakra she was supposed to provide to the clan's main family in another world. She originally went with Isshiki Ootsutsuki before they were separated under unknown circumstances. In the anime, upon her arrival, she was discovered by the people of the Land of Ancestors, who brought her before their emperor, Tenji. Identifying herself as the God Tree's guardian, Kaguya used a mysterious power to wipe Tenji's memories of the encounter and subsequently settled among his people, becoming recognized as his concubine. Growing closer with the emperor, she eventually fell pregnant. When the Land of That began to threaten the Land of Ancestors over a border dispute, Tenji attempted to prevent the outbreak of war by declaring that anyone who attacked the larger nation's representatives was to be executed, an order which she broke when she was threatened by them, resulting in her and her assistant becoming hunted by their land to be executed.

Losing all faith in humanity but still longing for peace, Kaguya believed that it was necessary for her to attain god-like powers in order to put an end to all of humanity's conflicts. So, despite her clan waiting to harvest that world of its God Tree, she defied the taboo surrounding the fruit and ate it. In doing so, she awakened the Rinne Sharingan and became the sole person on the planet endowed with chakra. Using her new-found power, Kaguya single-handedly ended the wars, and took control of the nations. For her deed of stopping the conflict, she received the blessing of the people and was worshipped as the Rabbit Goddess. After establishing peace and changing somehow, Kaguya used the Infinite Tsukiyomi on humans to transform them into an army of White Zetsu over the course of many years in order to protect her chakra from being stolen by other clan members. In the anime, not wanting mankind to perish, she freed some victims of the genjutsu and erased their memories.

While giving birth to her twin sons Hagoromo and Hamura, she dispersed chakra to them, making the pair the first people born with chakra. Ruling by herself and often resorting to cruelty, her dojutsu and jutsu were regarded with fear, awe and reverence by humans. At some indefinite point, the Rabbit Goddess had instead become known as a Demon. Eventually, Kaguya found herself ruled by her own desire to possess all chakra, which eventually turned her against her sons. Having devised a plan to absorb their chakra, she integrated with the God Tree and became the Ten-Tails, followed by her challenging the twins to battle.

Assuming the Ten-Tails was an incarnation of the God Tree that attacked them to recover the chakra from its stolen fruit, Hagoromo and Hamura sealed the beast's chakra within the former's body while using its husk as the core of Six Paths- Chibaku Tensei, creating a celestial body that would become known as the Moon. Hamura later took leadership of the Ōtsutsuki clan and departed to the moon to guard the beast's remains, while Hagoromo remained on Earth in order to spread chakra to humanity and teach them the concept of ninshuu. However, just before her sons could completely seal her, Kaguya had manifested her will in the form of an artificial human called Black Zetsu. With the agenda of reviving its "mother", Black Zetsu manipulated Hagoromo's eldest son, Indra Ootsutsuki, as well as his descendants within the Uchiha clan and his brother's descendants within the Senju in an attempt to get one of them to awaken the Rinnegan and break the seal. Madara Uchiha would eventually succeed in obtaining the Rinnegan, and Black Zetsu began secretly manipulating world events to have Kaguya revived.
