He did beat sasuke, he lost because Naruto went 1 tail on him, yeah Haku would have won that fight easily.Back before the Shippuden series when Haku and Sasuke fought do you believe Haku would have won if Naruto never showed up in the middle of the fight.
He tried doing that and it was too weak. just like sasukesasuke will use great fireball jutsu and melt haku ice jutsu
I disagree Sasuke was weak he was one of the top genin in the village and Haku was apart of the Hidden Village of the Mist AnbuHe tried doing that and it was too weak. just like sasuke
