[about Gohan] Strange. Where did the little one get all his power? That kid's stronger than any Saiyan I've ever fought. Hmm...I better keep my eye on that one. I wonder who he is. I'm sure I eliminated all the Saiyans except for Vegeta, Nappa, and Raditz twenty years ago. How'd he survive? Neither one of those misfits could possibly be his father. No matter. In the end, they all must be exponged anyway.
The time is now. I must crush these miserable Saiyans...because they're like pesky insects. Once you let them get a foothold, they can be hard to wipe out. Best eliminate them now, before they gain momentum.
No, I'm not ready!
My dear, dear friend. Who is ever ready to meet their final fate, hmm? Now feast your eyes on my ultimate transformation.
Come here, kid! You've gotta help me! If you know what's good for you, you will! You understand?
But I can't help you!
What are you saying? I know you can help! I've seen you heal other people!
I can only heal those who have a good heart. You...your heart is black from the people you've hurt.
Why...you little...unless you heal me you little brat, Frieza's going to wipe us all out!
Sorry, I can't!
Hey, come on! I don't have time for your stupid moral dilemma, kid!
[about Frieza] In my wildest dreams, I've never seen anything so powerful...I wonder what it will look like.
I'll bet it's the most hideous, ugly, repulsive creature in the universe.
