First the fight where Naruto First used the rasengan on him was not right considering if he knew it was coming wouldn't he have blocked it? He is equal to Kakashi which Naruto is definitely not yet since him and Sakura couldn't get the bells.
Another mystery is that we still have yet to see alot of his moves I believe. He has had only one real fight and even that one I am not sure if that was Kabuto for reals.
- Spoiler:
- He gave Naruto A scroll to help him but then he promises to kill him. Why would he do this without some alternative motive?
And unlike the Akatsuki, Leaf and Sand ninjas, among lot's of other characters that will either be bad guys or good guys we never really know where Kabuto stands. While one minute he is helpful the next he is trying to hurt them?
So I said all this basically to ask what do you think will happen to him?
