WTF!
first of all,goku only gets up to SSJ3 in dragonball Z but in dragonball GT he gets to 4,5 and 6 and fusion SSJ 4 with vegeta against omega shenron and in dragonball x whitch is a porn hentai series he gets to a power called "ten-kai" and in dragonball RF he goes to SSJ 7 and in dragonball AF he gets to SSJ 8,9 and 10 and fusion and if you dont believe me about AF, i have a video on youtube of it that i got of my japanese friend whos 11 and has a video i bought from him of AF in japanese when i visited there... his name is Kairo-san by the way, goku has 527 fases so far including ten-micha, ten-kai,sai-otakiro,pan-chirakoi and pan-chirakoi fusion with Sima ten kaio
