Zabuza and Kakashi both admitted Haku was stronger.

Part 1 Sakura > Haku.

No stop with your bs lol

 

[~Naruto&Itachi~]

remove their souls or seal them!

That's not killing....that's sealing

 

[cajin]

No. Just no. There are kids in this world..., doesn't refer to Haku. He just want to say that Naruto isn't stronger than Haku. So: Hey Naruto, you see that child Haku. Like there are children that are stronger than me, there are also children who are stronger than you.

Anyway, Sasuke who barely awakened Sharingan could read and dodge Haku. Kakashi is faster then him, better in using Sharingan, he could post earth wall just in case, then Raikiri Haku.

Haku is so powerful.
If he lived then he will surpass naruto and sasuke.
Too bad he died early in series

Haku had potential but he died
