Pan, General Rilldo and others in “Unfinished Business”

Now, as for you, Mr. General-with-the-stinky-attitude, if you don't wanna suffer anymore, then I suggest you apologize and give us back our Dragon Balls, and I mean this minute.

I'm afraid I can't do that. You see, the Dragon Balls don't belong to me. They belong to Dr. Myuu, who is their sole proprietor. They are an integral part of his grand plan to conquer the galaxy.

The galaxy? What? Ehh, why would he do that?

Eheh heh heh. Why did you decide to start walking rather than continue to crawl? And then why did you venture into space rather than continue to walk? Progress, my little friend. Natural evolution. Just as the inferior beings of this planet were replaced by our robot mutants, so too does forward progress dictate that this must happen throughout the galaxy. Dr. Myuu is the grand conductor of this orchestration, and there is nothing you can do to stop him! The strong must flourish and the weak must perish!

Alright, we'll play by your rules then, but don't be surprised if you find we're not as weak as you think.

Heh. An amusing theory, to say the least.
