Obito Uchiha

Obito Uchiha is a chūnin-level shinobi from Konohagakure and was a member of Team Minato and was initially thought to have died at the Kannabi Bridge during the Third Shinobi World War.

Obito's childhood was largely defined by his unwavering dream of becoming the Hokage. Following the tragic death of a girl who believed in him and he loved, Obito, who grew to hate the world that caused it, later donned a mask and began operating under the guise of Madara Uchiha, and later as Tobi, becoming an international criminal and the benefactor for Akatsuki. He was one of the three remaining living Uchiha following the clan's genocide. He was also the second jinchūriki of the Ten-Tails and one of the main antagonists of the series until his defeat.

During the Third Shinobi World War, Kakashi was placed in charge of the team for a mission to destroy the Kannabi Bridge, which would hinder Iwagakure from usingKusagakure as a relief point. Before beginning the mission, Minato and Rin gave gifts to Kakashi to celebrate his promotion to jōnin, though Obito had forgotten thus straining an already poor relationship. Minato would soon be called to the front lines, leaving the team to carry on the mission alone. The three were then discovered by Iwa-nin and Rin was captured. Kakashi elected to abandon Rin, believing it was more important to finish the mission before concerning themselves with her safety. Obito became enraged at the idea and insisted that they focus on her rescue. When Kakashi refused, Obito left on his own, remarking that Kakashi was worse than scum for abandoning his friends.

Obito found the cave the Iwa-nin were using as a hideout, but before he could make much progress, was found and attacked by a camouflaged Taiseki. Kakashi having a change of heart because of Obito's parting words, arrived and saved Obito, shielding him from Taiseki's attack, but damaging his left eye in the process. To save his team-mate, Obito awakened his Sharingan for the first time, allowing him to see through Taiseki's camouflage and kill him. The two found and released Rin from her restraints, prompting Kakkō to bring the cave down around them. As they made their escape, Kakashi's limited vision greatly hindered him, and when Obito noticed he was about to be crushed by a falling boulder in his blind spot, he pushed him out of the way and became trapped under the rubble in his place, crushing the right half of his body. With no way to escape, Obito accepted his fate and made an offering: to give Kakashi his left Sharingan as an apology for forgetting to get him a present earlier.

However in actuality, Obito was rescued by an elderly Madara Uchiha who found the younger Uchiha when the cave-in brought him to one of his tunnels leading to the Mountains' Graveyard. Though his Sharingan was miraculously unharmed, the entire right side of his body from the neck down was completely destroyed, prompting Madara to reconstruct half of his body using parts of Hashirama's living clone. Telling Obito that he now owes him his life, Obito instead declared he wanted to return to Konoha and be with his friends. Madara informed him that his new body would prevent him from becoming a shinobi again, and that in the end it wouldn't matter. Madara preached about the harsh nature of reality and how he has a plan to change the world. Still unconvinced, but otherwise unable to leave, Obito remained in the Mountain Graveyard to recuperate. During his recuperation, he met and became friends withWhite Zetsu and one of his many clone brothers while undergoing rehabilitation in order to use his new limbs.

On his way, Obito's left eye socket caught a glimpse of what his left eye was actually seeing, but dismissed it as a panic thought. Upon reaching the battlefield, he was shocked to see Kakashi had run Rin through with his Chidori.

As Rin died before both of them, their Sharingan matured into the Mangekyō Sharingan and Kakashi passed out quickly afterwards. The Kiri-nin attempted to claim Rin's body for intel.

Enraged by this, Obito responded by using a combination of his Kamui ability and Wood Release sprouting from his body which resulted in the deaths of all the Kiri-nin and ignoring Kakashi completely, Obito cradled Rin's lifeless body and, with Madara's words still ringing in his mind, vowed that he would create a world where she was alive again.
