Background

Kakashi is the son of the legendary White Fang of Konoha, Sakumo Hatake, and like him was considered a gifted shinobi. He graduated from the academy at the age of 5, becoming a Chunin a year later. However, his success came at a great loss; his father, once well respected in the village, fell into disgrace after choosing to save his comrades rather than complete a mission, causing Konohagakure to suffer in the war effort. Dishonored, Sakumo committed suicide after deep depression and a drop in his skills, which caused Kakashi to lead his life strictly by the ninja code. His White Light Chakra Saber, for which his father was nicknamed, was given to Kakashi.
He went on to become a part of the Team Minato, led by the future Fourth Hokage, Minato Namikaze, with Obito Uchiha and Rin, a medic-nin. Kakashi's relationship with Obito and Rin was very much similar to that of Sasuke's relationship with Naruto and Sakura respectively in which they share a complicated relationship that later developed into a close friendship. In the midst of the Third Great Shinobi War, at a meeting to hear their new mission, Kakashi was elevated to Jonin and received gifts from his teacher and team mates; a special kunai from Minato and a medical pack from Rin. After receiving their gifts, the Fourth informs the team of their mission: they must travel through the Grass Country in the midst of a conflict between Iwagakure and Konohagakure to destroy a bridge. Along the way, Kakashi’s team notices that they’re being watched from the trees by Mahiru, an Iwagakure ninja. Kakashi sees this as a good opportunity to use his newly created jutsu, the Chidori. He arrogantly ran off to attack the hidden foe, only to face off against Mahiru’s multiple Shadow Clones while Rin was captured by enemy Shinobi. Obito immediately stated his intention to rescue her, but Kakashi disagreed on the basis that they needed to complete their mission, opting not make the same mistake his father did. Obito then states that his father was a true hero for protecting his friends. Kakashi parted ways with Obito soon after, and as he reflected on Obito’s words and Rin’s prior kindness, he realised that his father had made the right choice after all. This prompted him to rejoin Obito in the rescue effort, claiming that Obito couldn’t survive on his own.

During the attempt to rescue Rin, Kakashi detected a Rock ninja, and yelled a warning to Obito, who was too slow to react. Kakashi jumped in front of Obito to save him from the enemy's kunai, losing his left eye in the attack. Obito, due to the shock of Kakashi's injury, awakened his Sharingan and killed their assailant. The two managed to rescue Rin, however, a rockfall technique was triggered, hindering their escape. It was then that Obito chose to make the ultimate sacrifice, pushing Kakashi out of its path. As he laid there dying, Obito had Rin implant his Sharingan eye in Kakashi’s damaged eye socket, referring to it as a gift, as he had never given Kakashi one before the mission started. He died shortly thereafter. As his first act with his new eye, Kakashi avenged Obito by killing the enemy ninja with his now-perfected Chidori technique. Obito's death had a huge impact on Kakashi's personality. Obito's flaky and unreliable traits were adopted by Kakashi, as we see in his adult age; constantly being late to meetings and making fake excuses to his tardiness. Kakashi also became more mellow, having adopted some of Obito's other traits such as his notion for teamwork.

Part I Team Kakashi (Team Seven)

Amongst the students and instructors at the academy, Kakashi developed a reputation for failing every potential Genin team that took the Survival Training Exam he proctored. When he was given Team 7—which consisted of Naruto Uzumaki, Sakura Haruno, and Sasuke Uchiha—Kakashi tested their individual skills, and their ability to work as a team. He gave them a Survival Training Test, which involved the team stealing two bells off of Kakashi's person; only those who retrieved the bells were allowed to eat while the one without one was forced to starve. Sakura's tunnel vision focus on Sasuke, Naruto's impulsive insistence on being a one-man show and Sasuke's arrogant superiority complex and loner attitude led the team to fail the Survival Training Exam. Only after Sakura and Sasuke tried to feed Naruto that he revealed the purpose of the test: teamwork. He then passed the team when Sasuke and Sakura said that they fed Naruto because their team was one.

Kakashi tells them that they are the first team to realize this. Before he started the Survival Training Exam, he invited them to a group session, where he got the chance to learn about their goals and dreams. At the start of their partnership, Kakashi seemed a bit wary of his team—especially Naruto, who he found to be quite annoying. Over time, however, his feelings for his team changed, and he took on a more brotherly role.







Part II Rescue Gaara

With Team 7 effectively dissolved-Naruto training under Jiraiya, Sakura under Tsunade, and Sasuke under Orochimaru-Kakashi spends the 2 and half years between Naruto's departure and return to develop his speed, particulary his sign-weaving abilities, making him an even more formidable opponent. Naruto and Sakura claim they can't track his movements. When Naruto returns, Kakashi is quick to put him and Sakura through a second bell test, in which their efforts to acquire the bells through force prove ineffective. Realizing this, the pair instead yell out spoilers from Make-Out Paradise's newest edition, Make-Out Tactics, distracting Kakashi and allowing them to recover the bells. Tsunade then appears and congratulates the two before officially forming Team Kakashi, with Kakashi as the captain and Naruto and Sakura as his subordinates. Later on, when word of Gaara's kidnap reached Konoha, Tsunade reassigned Team Kakashi's mission: to aid Sand and rescue Gaara from the Akatsuki.
