<P> In animated versions of the manga, Kakashi has been voiced by Kazuhiko Inoue in Japanese . Inoue was surprised about Kakashi's popularity within the Naruto fans and expected people to continue supporting him . In an interview, Dave Wittenberg, who does the voice acting for Kakashi in the English dub, comments that he feels he is similar to the character since he tends to have one eye open at a time and he becomes angry if he is interrupted while reading . He also added that what he likes most about Kakashi is his relation with his students, noting him to be "a very nice person". </P> <P> Kakashi Hatake is introduced as the leader in charge of Team 7, a new ninja team including Naruto Uzumaki, Sasuke Uchiha and Sakura Haruno . He first appears as a carefree character as he tends to lose track of time, and is frequently late to his appointments as a result . However, when testing his students, Kakashi reveals himself as a strong opponent to the point he fights while reading Make Out (イチャイチャ, Icha Icha) series of erotic novels . Kakashi is revealed to be very famous in the Naruto world, earning him the moniker "Kakashi of the Sharingan" (写 輪 眼 の カカシ, Sharingan no Kakashi) for possessing the Sharingan, gaining it from a member of the Uchiha clan he was friends with . It grants him the ability to mimic the movements and jutsu of others . Although most of Kakashi's abilities were acquired with his Sharingan, he also invented the Chidori and its Lightning Blade variation, a collection of lightning chakra in one's hand that uses the Sharingan's visual ability to lock onto a target . When first forming Team 7, Kakashi does not turn them into his students until instilling in them the concept of teamwork even if they have to break the rules he gave them . Kakashi continues to further this philosophy for the duration of Part I upon Sasuke Uchiha but is unable to get through to him before the latter's defection from Konoha . Kakashi also reluctantly participates in various kinds of challenges by his childhood friend Might Guy who considers Kakashi his rival . </P> <P> Kakashi's background is explored in Kakashi Gaiden, a six chapter series that divides the gap between Part I and II of the manga . Following his father's suicide, Sakumo Hatake aka the White Fang, Kakashi adopted the philosophy that the success of a mission must always come first rather than comrades in contrast to his father . Kakashi is assigned by his teacher, Minato Namikaze, to lead a mission that would turn the current war in Konoha's favor . When his teammate, Rin Nohara, is captured by enemy ninja, his other teammate, Obito Uchiha, convinces him to rescue her despite the mission's ending . After finding Rin, an enemy - induced cave - in crushed Obito's right half . With his dying wish and the possibility of enemy reinforcements, Obito has Rin implant his newly acquired Sharingan into Kakashi's recently damaged eye socket as a parting gift . His new eye in place, Kakashi flees with Rin as the cave collapsed, eventually completing their mission . Shortly after this event, Kakashi has to rescue Rin again who is kidnapped by Kirigakure; however, he learns that the Kiri, under the influence of Madara Uchiha, has made Rin as the host of the Three Tails, Isobu . Rin requests Kakashi to kill her so she may not be used by the Hidden Mist ninja as part of a Trojan Horse scheme against Konoha, but Kakashi is reluctant . She eventually forces herself on the way of Kakashi's Lightning Blade that he originally directed at the pursuing Hidden Mist ninja, killing her . An anime exclusive flashback arc in Naruto Shippuden covered Kakashi coping with what he endured during the war as he becomes an ANBU operative during Minato's time as Hokage and influences Yamato into becoming a member of the ANBU as well . Once relieved of duty in the ANBU, Kakashi becomes a Genin instructor prior to the events of Part I . </P> <P> Two - and - a-half years later in Part II, Kakashi reforms Team 7 . During the gap in time, Kakashi hones the Mangekyo Sharingan that he gained from result of Rin's death to master the Kamui ability that allows him to send any targeted object to another dimension . Because his students are now capable of taking care of themselves, Kakashi takes a more active role in the battles that go on during the series, particularly those with the criminal organization Akatsuki . When the Akatsuki leader, Pain, invades Konoha, Kakashi engages him in battle but he dies as a result of forcing all his energy . However, after his confrontation with Naruto, Pain decides to use all of his remaining power to revive all those killed in the battle at Konoha, including Kakashi . Following a brief encounter with Tobi, the Akatsuki's true leader, Kakashi becomes one of the generals to participate in the war against Tobi's army . As Naruto and Killer Bee continue to battle against Tobi and his forces, Kakashi and Guy arrive to join the fight against Tobi . During the encounter, Kakashi learns that Tobi is Obito, who in fact had survived his apparent death and had committed horrible deeds since Rin's death to destroy the world order that allowed their friend's demise to occur with Kakashi being left greatly stunned and also horrified at Obito's actions . Despite the guilt for what Obito has become, Kakashi is encouraged by Naruto to continue fighting and the battle ends with Kakashi managing to impale Obito . When Naruto is nearly killed by Madara, Kakashi and a redeemed Obito joined forces to protect Naruto by spiriting him off into the latter's dimension to be healed . After losing his Sharingan, Naruto using his new - found abilities to restore his original eye, Kakashi finds himself temporarily infused by the chakra - based spirit of Obito as he gains his friend's full Sharingan abilities and a Susanoo to help his team defeat Kaguya . Kakashi Hatake is the commander of the third battle unit in fourth great ninja war . Following the conclusion of the war, Kakashi is named by Tsunade as her successor, the Sixth Hokage, with his first act being to pardon Sasuke for his crimes . He holds this title for many years before finally passing it to Naruto, as revealed in the epilogue . </P>
