he didnt defeat kakazu, kakashi saved him. w/o him he would have lost
naruto was solo by genjutsu by itachi plenty of times.
sasuke beat naruto at orochimaru hideout
killer bee stopped raikage attack from impacting with naruto head.
paths had him beat when they pent him to ground.
I dont know what manga/anime your viewing. But it's clearly not Naruto XD
1. Naruto hit Kakuzu with a Rasenshuriken. He may not have died from it, but he was not gonna get back up.
2. Naruto and Itachi only engaged in 2 fights in shippeden. The first time was during the rescue Gaara ark, where "Itachi" lost. The second time was when Edo Itachi and Nagato fought Naruto and Bee. And as I said, Itachi switched sides. So thats a draw.
3. That Naruto and Sasuke fight was never finished, if it was then the story would have ended there. You can't call the fight a win or loss unless theres a distinct winner, and since Sasuke booked it, it was a tie.
4. You're clearly avoiding what happened after that. Yes, Bee stepped in, but right after that the Raikage charged at Naruto full blast. Naruto dodged the punch at the last moment, and the Raikage allowed him to move ahead because of that.
5. Pain *would* have defeated Naruto when he was pinned down, but then Naruto when 6 tails and broke free. And before you say "that doesn't count since it wasn't Naruto", Naruto then returned to normal and delivered the final blow on Pain. So he still won.
