Can Goku, Gohan and Vegeta beat Fat Boo?

[sei'taer]

Meh full power gohan isn't THAT weaker than goku and vegeta. All 3 of them felt at full power SSJ2 they could beat buu before the first power up, even if goku and vegeta seemed much more sure of it than gohan. And none of them felt they could beat post power up buu alone. He'd certainly be of help in a fight if buu didn't have his other advantages.

buu (first powerup) > SSj2 vegeta = SSJ2 goku > SSJ2 gohan ~/> initial buu.
