Dragon Ball Z, Season 3

Frieza:
Darn. I held back too much power.

Goku:
So, you couldn't do it. You couldn't go through with it after all, huh?

Frieza:
Huh?

Goku:
I don't blame you. Destroying both of us to make sure that I don't win isn't any way to fight. It's just another way of giving up.

Frieza:
You still don't get it, do you? Heh heh heh heh heh. I didn't plan on destroying myself, just you and the planet.

Goku:
Hm?

Frieza:
I can breathe in space and you can't. That means if the planet goes, then you won't have any more air to live on. And I shall be victorious. Five minutes. That's how long you have. This planet is still going to blow, the core has been completely disintegrated.

Goku:
Hmph. Five minutes is all that I need. It won't even take me that long to beat you and leave with my friends on my spaceship.

Frieza:
You underestimate me. The true depth of my power escapes you. Well then, it's time that you experience the ultimate Frieza! Yes, a very rare occurence indeed. One hundred percent of my true power! You never really had a chance to beat me! It's over!

Goku:
Can your body handle the stress from all that power?

Frieza:
Hmph.

Goku:
Well, I don't think that it can! In any case, I'm not going to give you the time you need to power up! This battle ends right now!
