Now, let's try this once more. [King Piccolo kicks Goku in the chin, sending Goku flying into the air. Piccolo then jumps into the air after Goku and punches him back down to the ground. After Goku slams into the ground, King Piccolo picks him up by the neck]
Why must I continually deal with these human fools? If it weren't for but a handful of annoying warriors, this invasion would be so pleasant. There's nothing more aggravating than an inferior adversary who confuses pure luck with prowess
I don't believe it. He flew right through me. How could he defeat me like that? So... I underestimated his strength. He's won for now, but my legacy on this planet will survive. [barfs one last egg] Good luck, my son. Get revenge for my demise. Destroy all of my enemies. [dies]
[to Goku] It's a shame that you have such great power yet you make such poor use of it. You need to learn control. Only then will you be able to past this test and meet with Kami.
Goku, our last fight against Piccolo showed I was nothing compared to you. But if a kid can reach such powers, think of what a trained master can do. At the next World Martial Arts tournament, I will surpass you!
Yes. You beat him and so you assumed you were the toughest in the world. But learn this now: no matter how strong you are, there will always be someone stronger who comes along. To stay on top, you must keep pushing past what you think is strength.
