if they want this fusion to work goku can't be in super saiyan mood and he would have to lower his power to be at naruto's level. the fusion would be a fail. but the again goku wanted to do fusion with hurcile so this may work
If you have read the latest Naruto manga you will understand what i'm gonnah say right now: God may have mercy of the poor soul that caused those two to fuse, 'cause they sure as hell won't P.S: great art Raz, love it
i know people say hoku would destroy naruto but think if they fuse u got goku's epic speed power and strenght and naruto epic ninjutsu imangin a fusion of rasnashiruken and kamehameha
