Hatake Kakashi

Kakashi is the sensei of Naruto, Sakura, and Sasuke. He is known as "the Copy Ninja Sharingan Kakashi" all over the world, and it is rumored that he has memorized over 1000 jutsu. At first glance you would never guess Kakashi is a very powerful jounin. He's very relaxed and sometimes even somewhat slow. He also loves to read his romantic (or is it dirty?) book "Come Come Paradise". However, in this case, appearances can be deceiving. Kakashi is known throughout the world as a formidable adversary and he was an apprentice of the Fourth Hokage.

Kakashi is a very good but very strict teacher. Prior to Naruto's team, he had never allowed any of the teams he was to teach become genins. He uses the same teaching methods the Third and Fourth Hokages used, and he emphasizes teamwork above all else. He feels that someone who does not understand teamwork is not worthy of becoming a ninja.

Kakashi has a sharingan in only one of his eyes. This is unusual because normally sharingan affects both eyes. The most likely explanation for this is that it was surgically implanted.
