Obito Uchiha (うちはオビト, Uchiha Obito) was a former team-mate and friend of Kakashi Hatake and a member of Team Minato who appeared in the Kakashi Gaiden arc. Obito graduated from the Ninja Academy at the age of 9, and was promoted to Chūnin at the age of 11. During the Third Great Shinobi World War, Team Minato was assigned the task of destroying the Kannabi Bridge. Because Kakashi had recently been promoted to Jōnin, he was to be left in charge of the mission. Before setting out, however, Minato Namikaze and Rin gave Kakashi gifts, something Obito forgot to do. Minato left them to go fight on the front lines, and Rin was soon captured by Iwagakure forces. Kakashi chose not to go save her, placing the mission's completion first, but Obito refused to comply, stating that, while those who break the rules are scum, those who abandon their friends are worse than scum. After that, they parted ways.
When Obito found where Rin was being held, he was immediately attacked by Taiseki. Kakashi, having had a change of heart, arrived in time to save Obito, while Taiseki used the Hiding with Camouflage Technique to disappear. Invisible, Taiseki was able to damage Kakashi's left eye. To save his team-mate, Obito awakened his Sharingan, immediately proving proficient enough with it to locate and kill Taiseki. Obito and Kakashi went to defeat Kakkō and save Rin, but once she was freed, Kakkō started an enemy-induced cave-in and escaped.
When Obito pushed Kakashi out of the way of a falling rock, his right side was crushed. Unable to free himself, Obito asked Rin to give Kakashi his remaining Sharingan, to make up for not giving him a gift earlier. Once the eye transfer procedure was complete, Kakashi moved forward to kill Kakkō with a perfected Chidori.
Sensing that reinforcements from Iwagakure have arrived and attacked them (causing the cave to collapse once more), he forced Kakashi and Rin to leave him in the collapsing cave. Obito was then crushed by the falling boulders while he was thinking about his two team-mates, sadly remarking how he was unable to fully deepen his friendship with both of them when they were already getting along well.
Abilities As a member of the Uchiha clan, Obito could use Fire Release jutsu, as seen in his fight with two Iwagakure ninja where he demonstrated his Fire Release: Great Fireball Technique. He was also keen on using kunai as he used them to kill Taiseki and later used them in his battle with Kakkō. Obito was also able to awaken his Sharingan and use it with great ease, despite being his first time using it. Furthermore, Obito was good at using taijutsu, which, together with his Sharingan and Kakashi's help, was proven an effective fighting combination.
