This has been bugging me for quite some time so I decided to make an account and post on one of the naruto forums I read from time to time. The theory surrounds narutos current training and my theory is as follows. Unless the completed rasengan is somehow a ranged attack wont it STILL be incomplete? The reason I say this is because of what yondaime told kakashi in the kakashi gaiden chapters. Chidori and Rasengan are basically the same style of attacks (a type of high damage palm thrust). But yondaime said chidori was incomplete because it involved kakashi rushing in and often missing and we have seen naruto miss rasengan a few times already. Toward the end of kakashi gaiden kakashi was able to complete the technique by receiving sharingan so he can predict the opponents movements and use the technique successfully. So assuming the completed rasengan doesnt change it into some kind of ranged attack and kishi sticks to what he said in earlier chapters wont naruto have to learn something else to effectivly deliver the rasengan to his opponent? Perhaps shunshin/hiraishin? Because I seriously doubt naruto will get sharingan or anything like it. And I dont think kage bunshin counts. I think its a pretty strong theory and it has support I just want to see what others think.
