"The Ten-Tails' Jinchūriki" (十尾の人柱力, Jūbi no Jinchūriki) is chapter 637 of the original Naruto manga.
With Obito's cry resounding throughout the battlefield, Madara muses that he had once told Obito that eventually, he would have to repay the legendary Uchiha for saving his life. Noting Madara's intentions, Hashirama tells both Naruto and Sasuke to deal with Obito since they were the closest to him. As a contingency plan, Hashirama and Tobirama create wood and shadow clones respectively to take on Madara in case it was too late to stop Obito. Meanwhile, Obito — whose hair was beginning to become thinner, and greyer due to the Outer Path: Samsara of Heavenly Life Technique — begins to reminisce his life as part of Team Minato. Sasuke, riding atop Aoda, begins to slither on the Ten-Tails to get close to Obito, and launches a black arrow only to be retaliated by the chakra receivers jutting out of the latter. Minato — having formed a shadow clone himself — teleports to Obito, who was reminiscing about the advice of his former sensei, and cuts him down. With shock, Minato realises that Obito had been the one who orchestrated the destruction of Konohagakure. As Sasuke notes that only Madara was left to be sealed to end the war, Obito simply smirked at their plan as it is revealed he had prevented Madara's control much to the surprise of Naruto, Sasuke and Minato, who had regrouped after witnessing the escape of the Ten-Tails and Obito's transformation as he became the Ten-Tails' jinchūriki.
