"Frieza: Oh my. You are so naive. You know nothing of the pleasures of this universe. Any desire that you have could be instantly fulfilled. But have it your way. Die if you must. But allow me to let you in on a little secret.

Frieza: Well, I haven't even begun to use my real power yet.
Goku: Yeah well I have some reserved myself.
Frieza: Yes, I know. Five. Five times what you've displayed, ten at the very most. But I...I've only used one percent of my power."
