Hatake Kakashi

 Kakashi Hatake (はたけカカシ, Hatake Kakashi) is a shinobi of Konohagakure's Hatake clan. Famed as Kakashi of the Sharingan (写輪眼のカカシ, Sharingan no Kakashi), he is one of Konoha's most talented ninja; regularly looked to for advice and leadership despite his personal dislike of responsibility. To his students on Team 7, Kakashi teaches the importance of teamwork, a lesson he received, along with the Sharingan, from his childhood friend, Obito Uchiha. After the Fourth Shinobi World War, Kakashi becomes Konoha's Sixth Hokage.

                  

Because his mother died when he was very young, Kakashi was raised during his early years by his father, Sakumo. Sakumo was famed throughout the shinobi world, having saved Konoha on at least one occasion; Kakashi in particular revered his father. During one of Sakumo's missions - after Kakashi was enrolled in Konoha's Ninja Academy - Sakumo made the decision to save the lives of his teammates rather than complete the assignment. The mission's failure had disastrous consequences for the Land of Fire, causing many in Konoha, including the teammates he saved, to vilify him for abandoning his duties. Disgraced, Sakumo committed suicide. Seeing what his father went through and determined not to make the same mistakes, Kakashi decided that following the Shinobi Rules must always take priority.

                     

In the Academy, Kakashi earned top grades, earning him recognition as a prodigy and the best of his generation. Ultimately, he became very popular amongst his peers. With his talents soon being recognised, at age 5, Kakashi graduated from the Academy at the top of his class in a single year. Upon becoming genin, he and his classmates, Rin Nohara and Obito, were teamed together under the leadership of Minato Namikaze.

Because of what happened with Itachi, the Third Hokage felt that individuals with kind hearts did not belong in the Anbu. He therefore thanked Kakashi for his years of service and relieved him of his duty, returning him to the standard forces.Over the years, he was placed in charge of several teams of Academy graduates, but none ever demonstrated the teamwork he considered to be so important. In the anime, he started worrying that his own methods were too harsh, but from seeing how his former underlings that he previously failed prospered due to his teachings, his faith was reaffirmed.
