The Ten-Tails' Jinchūriki

Summary
With Obito's cry resounding around the battlefield, Madara reminds him that he eventually had 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. As a contingency plan, Hashirama and Tobirama create wood clones 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 on 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 rods jutting out of the latter. As each and everyone begins to stop both Madara and Obito, Minato — having formed a clone — teleports to Obito, who was reminiscing the advice of his former sensei, and severs his left arm. With surprise and realisation dawning on him, Minato begins to question if Obito had been the one who orchestrated the destruction of Konohagakure which was simply responded by the thud of Obito's fall. Having fooled the others into thinking that he had fallen, 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 the Obito's transformation as he became the Ten-Tails' jinchūriki.
