ok, when Goku and Piccolo where fighting Raditz the highest power level Goku got to, was 1030 when he did his Kamehameha, the highest Piccolo got when he was doing the Light of death was 1330, but when Gohan got mad because he could hear his father(Goku) screaming because Raditz was cracking Goku ribs, his power level was 1307! he was more powerful then Goku when Goku did the Kamehameha! Gohan was not more powerful than piccolo at the time but its still cool Gohan got that powerful when he was only four. ok so in the dragon ball super manga trunks super Sayian 2 was as powerful as Goku's super Sayian 3 that's cool. just thought i'd tell you guys that because I thought it was cool.
