@fein, i don't know about naruto melee power, i talk mainly about the ball thing because that's his strongest move as far as i know, ( dropped naruto ages ago )

@tetris, if he shoot at a small scale, not enough to destroy the earth, as you can see in the anime, manga, those beam take seconds to charge and they travel quite slow, so obviously the trio would have plenty of time to dodge, to a safe space , or even behind goku and strike immediately, since goku HAVE to hold the beam for a few sec.
