Kaguya Ōtsutsuki was a member of the Ōtsutsuki clan and the matriarch of a branch family, including her children Hagoromo and Hamura. Long before the founding of the hidden villages, during an era of endless war, Kaguya consumed the fruit of the God Tree and became the first wielder of chakra on Earth, before later merging with the tree to become the Ten-Tails. Kaguya was a pale-skinned woman with delicate facial features. She had extremely long, sweeping white hair (grey in the anime). Kaguya possessed white clear eyes and her eyebrows were cut very short and round— a symbol of nobility, and she wore a red shade of lipstick on her lips. In the anime, after consuming the forbidden fruit, her hair grew even longer, dragging across the ground and her fingernails grew long and dark. Most noticeable, she grew two brown horns that stuck out from her head and a third eye formed in the centre of her forehead. She wore a high-collared hime-kimono which has tomoe running down the centre and edges of the gown and in the anime, adorned with intricate gold and purple lines. When her power went out of control, Kaguya transformed into a conglomerate of the tailed beasts. Her original body turned into a gigantic rabbit creature with a humanoid upper body, jagged teeth and her signature Rinne Sharingan on its forehead. On its back was a great spherical mass of chakra with the heads of the nine tailed beasts emerging from it, along with chakra arms. When Kaguya had her powers stripped away, she briefly reverted to her Ten-Tailed form, with each tail ending with the head of one of the tailed beasts and the tenth ending with her rabbit head. As noted by her son Hagoromo, Kaguya was once truly a good and caring person. This was expanded on in the anime where despite displaying an apathetic personality, she longed for peace and eventually fell in love with Tenji, who shared a similar dream, even though she never openly displayed her feelings for him. She also cared deeply for her hand-maiden Aino, even though she never openly displayed emotions to her either until just before Aino's death. However, she was also treacherous and ruthless towards those she did not care about, as she betrayed fellow clansman Isshiki and nearly killed him; Amado speculated it could either be personal enmity or her desire to have the chakra fruit for herself. After obtaining the ability to manipulate powerful chakra from the God Tree's fruit, Kaguya had grown despotic and developed both a god-complex and messiah-complex, believing that chakra rightfully belonged to her alone and that only she could protect and unite the world. Black Zetsu noted that Kaguya tried to love humans for the sake of peace, but her distrust in them proved far too great as she came to believe all they did was fight and destroy the world. Despite her initial desire for peace like her sons, grandsons, and in the anime, her lover, Kaguya ultimately caved into corruption from her power and lost faith in humanity's ability to do what is right. As a result of her losing faith in humanity, Kaguya opted to use her great and terrible power to submit everyone to her will. As Hagoromo noted, humanity around that time began to fear her as a demon. She uses the archaic pronoun "warawa" when referring to herself — a sign of ancient nobility. Kaguya also displays a degree of affection, as she appears to care very deeply about the Earth, viewing it as a nursery that she does not want humanity itself to damage any further. In the anime, although she had affection for her lover, Tenji, it was not strong enough to stop her from trapping him in the Infinite Tsukuyomi when he betrayed her for his own pursuit of peace. Although she openly stated that she hated her own sons for using their inherited chakra against her and created the Ten-Tails to take it back by force, she openly wept when looking at Naruto Uzumaki and Sasuke Uchiha, who reminded her of them, hinting that part of her still loved her sons. In the anime, Hagoromo and Hamura understood that their mother committed immoral acts for the sake of protecting them from the clan that she previously defected from, and they still felt affection for her because she was simply a mother doing what she could for her children. Even Kaguya herself told her sons prior to their battle that she had given them nothing but unconditional nurturing and protection, and willingly shared her chakra with them before their betrayal prompted her to try to claim it back. However, whatever love she harboured for her children was small, as shown in the anime where she was willing to take Hamura hostage and force him to fight Hagoromo in order to reclaim her chakra. Although, Kaguya did claim Hagoromo's love would prevent him from killing Hamura, suggesting she wanted to claim her chakra back without killing her children. It was later revealed she was on a mission to provide chakra to her clan, but after falling in love with a human and bearing his children, she created a White Zetsu Army to fight them off and protect not only her children, but the inhabitants of the Earth. This suggests that had it not been for her clan, she would have been a benevolent ruler. While her belief that chakra should belong to her alone made her somewhat obsessive in retrieving it from everyone else, she is willing to listen to Black Zetsu's suggestion on killing Naruto to prevent him and Sasuke from sealing her away, though she expressed reluctance that she must destroy a large reservoir of chakra to preserve her freedom. Despite her sombreness, Kaguya can nonetheless be stunned by unexpected events, as one of Naruto's perverted ninjutsu caught her off-guard, thereby allowing him to land a hit on her. Naruto stated that unlike all his previous foes, he couldn't empathise with Kaguya at all, as he felt she completely lacked a heart. Hagoromo wasn't sure why Kaguya ended up the way she did, but believed her eating the chakra fruit may have had something to do with it.
