If my enemy is a magical girl, I will not stand in awe as she goes airborne, drops all of her clothes, and starts spinning in preparation to transform. I will wait until her regular clothes are gone, then yank her down and start fighting. If her shock at my breaking the Law of Uninterruptable Metamorphosis doesn't paralyze her, the fact that she's in her birthday suit will.
Now, we're going to power up. You stand there and be quiet, I'll tell you when it's time to fight."

Freeza: Ninety-eight...percent! Almost...at maximum power!
Goku: That's right, you go right on up to 100. The only reason I'm waiting so patiently for this "grand unveiling" is to have the honour of taking you down at your best.
Vegeta: (watching Cell transform) He's certainly taking his time; this had better be worth the wait.
Trunks: There's no way I'm letting this happen! (opens fire, but his blasts just bounce off Cell's aura)

I just love how easy it is to get away with this sh*t with you people! I want to transform, you just sit there and let me! I want to blow the planet up, you just sit there and let me! I want to reach 100% power, AND YOU JUST SIT RIGHT THERE AND LET ME!

Why do I let people do that?!

Wilfred: When I saw you before, you said that your people could change, like your whole body.
Doctor: I can still die. If I'm killed before regeneration, then I'm dead.
