Obito Uchiha

appeared in the Kakashi Gaiden arc as a former teammate of Kakashi Hatake, and a member of Team Minato.

Background
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. 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, and Taiseki used the Hiding Camouflage Technique to disappear. Invisible, Taiseki was able to damage Kakashi's left eye. To save his teammate, Obito awakened his Sharingan, immediately proving proficient enough with it to locate and kill Taiseki. Obito and Kakashi went to save Rin, but once she was freed, an enemy-induced cave-in started. Obito pushed Kakashi out of the way of a falling rock, and his right side was crushed. Unable to free himself, Obito asked Rin to give Kakashi his remaining Sharingan eye, to make up for not giving him a gift earlier. Once the eye transfer procedure was complete, Rin and Kakashi were forced to leave, the cave continuing to collapse around them. Obito was then crushed by the collapsing boulders as he was thinking about his two teammates.

Personality
Obito was constantly tardy, always claiming he had been doing a good deed, such as helping an elderly woman carry her luggage. Minato referred to this as the truth, though Kakashi didn't believe him. Obito was also a little stubborn at times, yet, unlike Kakashi, who was very strict of the rules and regulations, he was usually carefree, and would rather save a teammate than complete a mission - the same as Kakashi's father, Sakumo Hatake. Obito would also lie to get out of trouble or just an uncomfortable situation - whenever he would start crying, he would claim he had something in his eye, though usually at the time he had his goggles on. Obito had romantic feelings for his female teammate Rin, though he never revealed it to her, not even when he was dying.

Obito has similar thin facial structure to Naruto Uzumaki, and they both also have similar personalities. Both were desperate to get attention as a child, they both have an epic rivalry with their other male teammate (Sasuke for Naruto and Kakashi for Obito), and they both have romantic feelings toward their female teammate (Sakura for Naruto and Rin for Obito). They were also considered "goofballs" or "knuckleheads" because of their recklessness. Unlike Naruto, however, Obito seems to be more conserved, not screaming out or recklessly challenging unless forced.

Abilities
Obito,as a member of the Uchiha Clan could use Fire Style.In his fight with two Iwagakure Ninjas he demonstrated his Fire Release: Great Fireball Technique.He was also keen on using kunais as seen when he killed Taiseki and later in his battle with the other Iwagakure Ninja.Obito was also able to awaken the Sharingan, his clan's kekkei genkai.Despite being his first time using the Sharingan,he was able to use it with great ease.Furthermore,he was a good Taijutsu user and with his Sharingan activated he could take down an oppontent in synergy with Kakashi.

Trivia

 * Before Tobi was revealed to be Madara Uchiha, several fans hypothesized that he was Obito Uchiha, as his only shown eye was the opposite of the eye that was inserted in Kakashi. They also have similar personalities and hair styles, as well as the same blood type, "O". The spelling of Obito was also similar to Tobi, creating the fan reference of ObiTobi, or Tobito. Even though Tobi has been referred to as Madara several times in the series, some fans still insist that Obito is somehow connected to Tobi or Madara.
 * He and Izuna Uchiha have some similarities:
 * They both died in battle.
 * Both gave their Sharingan to another person.
 * They have the same birthday as well as the same blood type.
 * Obito's first appearance in games is Naruto Shippūden: Narutimate Accel 3.
