@jazmac: Caught you in your own web of hypocrisy. Your stupidity is on a whole new level, I never talked about one shotting you did my exact words is "by your logic". Please GTFO of this thread, if you will not give any intellegent facts about this fight.
@SpeedForceSpider: We don't actually know how powerful Gohan and Krillin were when fighting Ginyu. Personally I think they were stronger than Ginyu by that point hence why they were actually beating Ginyu. The last confirmed power level before that point was Gohan's being above 20,000 against Recoome, but that was anime only. Gohan got beaten to near death at the end of that battle so obviously he would have become far more powerful as a half sayain after eating a senzu bean.
Vegeta himself went from being someone who was getting destroyed by Recoome to being able to easily defeat Jeice, so we can see that after recovering from near death he too became far more powerful. Gohan was a lot more badly beaten up than Vegeta was so it stands to reason his power increase was a lot higher too.
A V Jump scan states that Gohan was 200,000 before his fight with Frieza. Obviously it's not canon but it gives an idea of how much more powerful Gohan would have become from the time between meeting Guru and fighting Frieza. I'd say Gohan was probably around about 30,000 by the time he fought Ginyu in Goku's body.
