Naruto Season 1 Episode 9

Kakashi: (to Haku) From the markings on your mask, I would say your a Tracker Ninja from the Village Hidden in the Mist.

Naruto: Hey you...the freak with no eyebrows!

Tazuna: He's not just following. He moves the same way at the same time.
Sakura: How's he doing that? How Sasuke?

Sasuke: Wow, so many hand signs, and he mirrored them all perfectly, instantly.

Sasuke: Don't brag, you just lucked out.
Tazuna: The whole thing was a fluke.

Naruto: Stop right there! Shadow Clone Jutsu.
Zabuza: Oh! Shadow clones...and there's quite a few of them

Haku: Your struggle is over now. Now, I must deal with the remains. There are many secrets in this body. They must not be allowed to fall into the wrong hands. Please excuse me. Farewell!

Zabuza: (After being forced to release Kakashi) Damn kids!

~Japanese version

Kakashi: In this world, there are kids younger than you, and yet, stronger than me.

Naruto: Hey! Who do you think you are?!
Kakashi: Easy, Naruto. He's not our enemy.
Naruto: That's not the point! Did you see what he did?! Zabuza was huge, and powerful like some kind of monster! And this kid, who's no bigger than me, he brought down Zabuza with one move! Like it was nothing! What does that make us? We're just stubmling around. We don't know anything! How can I accept that?!
Kakashi: Well, even if you don't accept it, still, it did happen, Naruto.

Zabuza: (Thinking) What? Is this his genjutsu?
Kakashi: Water Style: Giant Vortex Jutsu!
Zabuza: Impossible!
(Zabuza gets swept away by a giant wave)
Zabuza: (Thinking) I was going to create a vortex, but he created one first! He copies my jutsu before I can even do it! I CAN'T KEEP UP!

Zabuza: (Thinking) Did he read my mind? Damn! That...
Kakashi: ...freaky eye is really pissing me off! Right?

~Japanese Version

Zabuza: Can you see the future?
Kakashi: Yes, and you're about to die.
(Two needles hit Zabuza in the neck and Zabuza falls.)
Haku: You're right, he died.

~Japanese version

Zabuza: You're nothing but an imitation!
Zabuza and Kakashi: You can't be the real thing, you bastard!
(Zabuza gasps)
