i never noticed the story logic of this when i saw it as a kid. so the pretense for having Goku fight against Buu in SSJ3 and show off his skills with exposition was to "buy time for Trunks to get the Dragon Radar"
has Buu already killed everyone in this city yet? maybe goku shouldn't have thrown him into a building?
Vegeta's move is a ki wave barrage? seems kinda common
seriously. Dragon Ball GT was a lot of fun sometimes. its main problem was that it forced us to watch characters with the power of gods struggle against worthless peons to pad the runtime.
THIS SERIES HAS THE SAME PROBLEM.
ordinarily, Id say that Yamcha COULD have beaten Frost, since Yamcha is almost undoubtedly stronger now than Frieza was on Namek...but then again, Yamcha would ABSOLUTELY have fallen for that poison needle
