The Current Obito

Summary
Asking Obito if he hadn't had enough of their genjutsu battle, Kakashi and Obito form the seal of confrontation as they begin their real battle. They start to think back to their childhood days as young ninja, when they fought under the instructions of their sensei. Kakashi remembers the "old Obito", who was just like Naruto, and resolves that to protect Naruto and the old Obito, he will have to defeat the current one. As both men deliver final blows, Kakashi impales Obito directly through his chest with a lightning-infused kunai, leaving Obito heavily wounded, while Obito stabs Kakashi in the side with one of his black rods. Obito, unwilling to give up as well, states that defeating him will not gain any advantage to winning the war. As Kakashi observes, Obito warps back to the battlefield. Meanwhile, Madara impales Hashirama's wood clone, and notes that Hashirama was putting too much energy into restraining the Ten-Tails. Though the clone disagrees, it is split in half before it can complete its statement. As Obito arrives on the battlefield, Madara decides that Obito had served his purpose to him and though he wanted to fight Hashirama before he became a jinchūriki, the situation could not be helped. Forming a seal which affects Obito whose right side begins to spike out black rods and turn black, Madara declares that it was time to revive him with the Outer Path: Samsara of Heavenly Life Technique. As this occurs, Obito remembers Rin once again before forming a seal of his own and letting out a cry which draws the attention of many on the battlefield.
