tsunde-sama50 I think you may want to re-watch ep 76-80.

As for Haku, Naruto didn't really fight him, that was Sasuke. Sure, he used the kage bunshins, but didn't really do anything. He was trying to escape more than attack. Naruto beat him, but it wasn't really a fight (more like an ass-whooping) once Naruto powered up.




Personally, I think Gaara was Naruto's toughest opponent. But his toughest match would be a toss-up between the Neji one and the Gaara one. Sure, Gaara was stronger than Neji, but Naruto really had to struggle a lot more in the final chuunin exam (except maybe in the very end of the Gaara fight).
