yeah but that's unfair... 3 vs 1?? they lose just for that reason.. they can't beat goku 1 on 1... and ill agree that 3 vs 1, goku would probably lose.. ok ill give ya the title... even so at that point he beat freeza and fought almost even with cell... he killed freeza and freeza was the king of blowing up planets....  instant transmission is beyond a teleport... he can even use it to reach king kai's planet which is in the world of the dead... ichigo doesn't have the power to go one on one with goku and neither does luffy... ok so that leaves naruto... no ill admit that i stopped watching naruto after the first series.. i did watch a few episodes of shippuden but not enought to get into it, but from what i know about him he would lose 1 on 1... his specialty is rasen and kage bunshin... clones would mean nothing to goku cause he just power up and blow the away with his energy force.. naruto has to split his power to make clones and goku killed about 1000 metal coolers wsith just at ssj2 so that wouldnt work.... that leaves rasen... which is just taking his energy and making it spin like a drill... that might pose a threat but goku would just flash behind him and hit him with a kamehameha and that would be it.....

like i said, what i say means nothing... its just specualtion really.... if the show writers wanted to make someone stronger, all they have to do is write it... and i admit that im biased on the subject... dbz for the win lol
