Goku: It will be more interesting if he fights at full power.
Vegeta: It doesn't matter how strong he gets, I'll be stronger. I'm the Prince and a Super Saiyan!
Gohan: I won't intentionally let him get stronger, but I'm going to draw this fight out so I can torture him and give him a chance to get stronger anyway.
Gotenks: I'm going to win, but I better act weak so it will look impressive. I look totally awesome, and not at all like the retarded child that I am.
Future Trunks: KILL IT NOW!!!
