The Ten-Tails' Jinchūriki
As the Shinobi Alliance wonders about the Ten-Tails disappearing from the battlefield, asks to explain what happened, and it is explained that the beast's body and chakra were completely absorbed by the enemy. explains to and that never tried to revive from the beginning, but was actually making himself the Ten-Tails' jinchūriki. and soon realise how big of a threat just appeared, and the First Hokage pins Obito, only for the new jinchūriki to destroy both the restraints and the barrier with chakra arms.
As Minato tries to call out to his former student, who barely recognises his own name, the other reincarnated Hokage start attacking the enemy, using their immortality to study the enemy's power. His predecessors being easily knocked out, with Hashirama forced to take on Madara, Minato goes on the front trying to exploit Obito's inability to suppress the Ten-Tails. In his mind, Obito gets his consciousness ripped by the Ten-Tails but ultimately manages to take control of the monster, gaining a new form and making an attempt to kill the enemies in one single blow.
