Son Goku - Naruto Uzumaki SWITCH !

With goku's personality and determination to be the best, together with his incredible ability as a fighter (sure, he is a dumb ass and naive in most of the aspects of life, but he is a genious when comes to fight, just see him fighting piccolo at the 23 budokai for example) I see him becoming the strongest ninja ever. He would probably even invent a jujitsu which would resemble kamehame lol.

Naruto, well, as someone said, would probably die in chapter one lol. Anyway, with the right training he could have become strong, yet I doubt he could survive a fight against vegeta like goku did, or even come up with the idea of surpassing the super sayan level during the cell saga.

well naruto wouldnt last, but im goin to say he lasts to the saiyan saga when vegeta and nappa arrive, even though he would be long dead by now and its impossible for him to live lets just say he does, so vegeta reads his power level And shouts impossible its over 9 thn tht stupid bird chirpin plays, nappa says what, vegeta says its over 9 again, so vegeta decides to fight him instead of nappa, so naruto starts hiting vegeta with a flurry of punches vegeta just stands there laughing then vegeta touches naruto on his head he goes flying back into a mountain unleashes the kyuubi (9 tails) vegeta playes she loves me, she loves me not with his tails when all the tails are gone vegeta finds out she loves him :L lmao. So vegeta becomes the main character and becomes good for some unown reason :L, marries bulma and the first to reach a super saiyan, super saiyan 2, super saiyan 3 and 4 and saves the universe again and again :L

All this happened because naruto was a pansy and couldnt defeat vegeta, therefore vegeta becomes the main character because he defeated the main Yay go vegeta

P.S Vegeta rocks
P.S.S If only this could happen Vegeta always gets his ass kicked
