It's been a long time Goku. And you've gotten so much cuter since then.
Can't control your own strength, can you little Goku? That will come to haunt you, I guarantee!
Ha ha! I think the runt has forgotten with whom he's dealing!
No. But I think you have.
Ha! Poor Frieza. You were once considered the fiercest fighter in the universe, and now you're just a simple...well, nothing but a slouch.
Uh! How dare you call me a slouch, you idiot! Wait, Cell! Look above you. (Goku is above Cell)
You know Cell, I was always taught that if you spent as much time training as you do criticizing others, then your fighting truly suffers.
(to Nappa) You're still the brainless idiot who knows only how to destroy! One would think that a man with your experience would know when to call it quits, you bald-headed buffoon. I recommend you split town Nappa. Immediately. Unless you want to be killed by me again.
NNappa
Argh!!!! (Nappa runs at Vegeta, only to get blasted to death) Ahhhhh!!!
You've completely lost control of yourself.
Long time no see Vegeta.
What is this? A class reunion of evil losers? What do you want?
Just the usual genocide and extinction of your entire race and people.
(after Goku is frozen into an icicle) Hey there, Goku! You look cold! I warned you about this place and the tricks it hides but don't fret, there's plenty more waiting for you when you thaw out in twenty years!
