Frieza and King Cold in “Unfinished Business”

I will make him suffer for what he did to me! I will make this whole planet suffer!

Yes, do be quick about it, I'd rather not stay too long on this pathetic little mudball, not that I don't just love it here, but I still don't see why we can't simply destroy the planet right now!

You can be absolutely naughty father. It's impressive. And here I've always wondered where I picked up my knack for it.

I take great pride in the fact that I have taught you all the necessary skills of life. Use them well.

Indeed I will. For it just so happens that I have also learned from you the fine art of revenge. Allow me to demonstrate by vaporizing all of the Saiyan's friends one by one. Ha ha ha ha ha! Aha ha ha ha! My! Oh my! Ha! Won't he be surprised when he returns home and finds no one here to welcome him but me!
