Какаси Хатакэ
Kakashi Hatake is the easygoing, smart leader of team 7, consisting of Naruto Uzumaki, Sasuke Uchiha and Sakura Haruno. Kakashi had a dark past, but is unaffected by it as an adult. He was a very vital key for Naruto's success, training him to be a great ninja. Kakashi is a master of the Sharingan, which he gained as a present from his late friend, Obito Uchiha. Kakashi's original eye was restored late into part 2 of the series. Kakashi is killed by Nagato, who later repents and revives him. Kakashi succeeds Tsunade as the sixth Hokage in the late parts of "Naruto Shippuden".
