Goku, Vegeta and others in “Unfinished Business”

Ha! Ha! [Goku keeps charging]

Vegeta

Power level's eight thousand! How? Wait, it's over nine!

Nappa

Vegeta, what did you say his power level is?

Vegeta

It's over nine thousand! Ha! [Vegeta takes off his scouter and crushes it in his hand]

Nappa

Nine thousand!? There's no way that can be right! It can't!

Don't be so sure. I'll have you know I was trained in the art of Kaioken!

Vegeta

Huh? Kaioken?

Nappa

Kaio-whatever! Who cares!? I'm still gonna crush you! I don't care what you've learned!
