Wow dude your a moron. First of all Naruto is powerful as heck he is easily top 5 in the narutoverse so saying somone got beat by him and saay they are weak is retarded.^^^^ But why? he has gottenn his A$$ whooped by a 16 year old? like come on
Anyways Naruto fought Pein after he just destroyed the village, couldnt use deva path, Naurto had a ton of info and he had the frogs on his side, then had hinata and Minato save him. Quit acting like naruto could have beaten him on his own, cause if he was alone he would of been fooderized. And if deva was active in the start of the fight even with all naruto had he still would have been taken out with ease. Also pein was only trying to capture not kill, he could have killed naruto anytime he wanted. Deva pinned him down and could have driven a poll right through his skull.
Nagato is powerful as hell and Naruto can only challenge him as BM, KM got fooderized while fighitng along side Bee in seconds while Nagato wasnt even able to walk. Nagato has crazy amounts of chakara, Mastery of rinnengan, all chakara natures, knows almost all jutsu, op summons, etc etc etc
Only people who can beat or challanege Nagato is Madara, Obito(cause of beasts). BM Naruto and Hashirama are debatable.
Maybe you should go read the manga alittle more you sound like an idiot.
In conclusion Nagato is powerful and you my friend are a fool.
