What are some of the qualities that differentiate Kakashi from Naruto?
Well, Kakashi has the Sharingan eye. He doesn't have as much
chakra as Naruto does, of course. Naruto is always charging into a
battle without even thinking, which is not something Kakashi ever
does. Also Naruto takes things more emotionally than Kakashi does.
That's all I can think of, really.
