Well, it's been mentioned before, but Kakashi is one of the Leaf's top ninjas. Why would he need to copy a Jounin level technique from Naruto? He doesn't. There is no chronological fact in your theory, just assumptions. Just because he saw Naruto perform Kage Bunshin, does not mean he copied it.Ok one more shot on Range before I move on to Raijin's comment. Kakashi knew about buushin and gates before. But did he ever perform them? Chronological fact from the story is NO. Kakashi PERFORMS abilities AFTER he was exposed to them. You have no evidence to say that he could PERFORM them before. All you can say is that he "knew of them" prior.
Kakashi just tells Asuma and Kurenai to just close their eyes, he did not explain what the Mangekyou Sharingan was. It seems like he knew something about it, but not thoroughly. Itachi is the one who explains to Kakashi the power of his Mangekyou Sharingan.Second point. Ok, say what you're saying is right Kakashi knows all about Gates before Lee does it. Does that fucking mean he knows all about Mange when he explains it to Asuma and Kurenai what Mange might do if they look in his eyes? NO IT DOES NOT. Otherwise Kakashi knows Mange Sharingan as well as the Gates since "before those two were itches in their daddies pants".
Well, I have the Official Naruto Character Data Book (published/released by Jump Comics & Kishimoto) which states that Kage Bunshin is used in the Dance of the Crescent Moon. With Kage Bunshin, you are unable to distinguish which clone is the "original" since chakra is divided evenly among them. The Kage Bunshins were used as distraction as the "real" Hayate attacked from above. With regular Bunshin, since it is a low level skill and creates "false" clones, a highly skilled individual is capable of spotting the real person.Hell no he didn't. If Hayate did, the buushins would have done damage instead of forcing Hayate to jump down and make an actual blow from above. And only 3 buushins from a jounin? HAHA. Naruto can do 100 without Kyuubi. It was a totally different jutsu seeing how it gained praise from the Sand Nin.
BakaShinji, you have failed to respond to the questions I have asked from you. Itachi never worries or comments about Kakashi copying his techniques. As I mentioned in a previous post, please provide the chapter & page #, you are possibly confusing this incident to Kabuto's comments to Baki concerning Kakashi copying his techniques.
