Kakashi Hatake is introduced as the Jonin (elite ninja) 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 and tends to lose track of time. He loves reading a particular set of novels, his impressive ninja-copy skills, a mask that covered most of his face, and a great head of hair. With his ability to copy nearly any jutsu he saw in action, Kakashi certainly put his own body through its paces as well.
