Naruto would Beat out Kiba, point blank.if kiba had kept his composure naruto would have lost.
neji got arrogant and began toying with naruto which resulted in his defeat, as we all know an active byakugan sees EVERYTHING, including a punch from below. and not to mention in close range combat neji is faster than sasuke,, so y is it that he wasn't able to dodge one punch?
there would have been no fox if hinata had not jumped in when she did. and if the yellow flash did not contain the fox naruto would have killed himself (the nine tails was not only to great for pein, but naruto as well) god realm is the only one that is truly powerful the others are just support.
in deidara's case you state the impossible naruto had no high range vertical moves at that time (in fact he still doesn't) from a distance deidara is probably in the top 3 most powerful ninja. he even wears the scope to heighten long distance vision. and deidara has shown competence in short range combat when he fought sasuke.
Neji woulda coulda shoulda won. But his personality defeated him. But now Im more than sure he would beat naruto, and the Raikage from that matter.
Pein, idk what to say about him........as for the fox, the fourth knew the day would come to where he would need to save Naruto from the sealed fox, it was pre-planned. So no, Pein was the only one that would lose there.
Deidara isnt strong enough to take A rasengan, And we all know Naruto is a straight genious when it comes to close combat. He would Find A way
