“Saiyans Emerge” quotes from Dragon Ball Z

Vegeta

I will take care of everything now. There is no need to attempt the training, Kakarot, because I'm sure you will not survive it. Besides, I guarantee that I won't be needing any of you to help me take care of the androids.

Tien

You fool!

Piccolo

Listen, I don't know how powerful you think you are, but you're underestimating our enemies.

Vegeta

Heh heh heh heh heh heh.

Tien

While you were in that room, Cell swallowed up Android 17 and transformed, so don't try to tell us you can handle it. You don't even know what you're up against.

Android 18

[to Android 16] Oh, great. I think you're starting to malfunction. All you've been doing is staring at these birds all day long. What do you see in those things anyway? Don't you care that Cell's going to suck me up like he did 17? Don't you care that he's going to kill you?

Bulma

Vegeta, you don't look that different. Why didn't your hair grow at all?

Vegeta

Uh...for your information, a pure Saiyan's hair does not change from the day that he is born.

Bulma

Oh...

Goku

Is that true...how 'bout that!

Bulma

I guess that's why you've never needed a haircut.

Goku

Hey yeah. But I wish I could do something about these split ends. Ha ha ha.

Bulma

Try shampoo.

Vegeta

I don't have time to listen to Kakarot's hair problems.

Bulma

[about Saiyan combat armor] Hey, aren't you going to wear yours?

Piccolo

I am a Namek, not a Saiyan. And I'm not going to dress like one.

Tien

That's right. I refuse to wear the same suit as Vegeta! Not after all of the horrible things he's done.

Why is Cell so determined to become more powerful? He is already stronger than any other creature on this planet. What is he trying to achieve? What is the point to this destruction?
