@Son_Wukong: aaaaaaand that's impossible. the pure kinetic energy of the punch would be more than enough to destroy the moon. yet it doesnt. unless you tell me that a ki based punch now is able to discriminate between targets (lets do a punch with enough force to destroy the earth-accidentally hits the ground...lol joke.)
@eddz99: ok how about spiderman overwhelming thor? good enough. a ki enhanced punch packs a certain ammount of striking force i think that's obvious.
Nope, an ordinary punch = striking force, a ki enchanced punch = striking force that is ki enchanced :3, then how do you explain frieza getting hurt by ssj goku's ( not really ki enchanced ) punches while he was not even hurt by piccolo's special beam cannon which would have been way above planet level at that time? :P , that's why attack potency exists...
I don't really read marvel i just copied that point from 2 people but still, you cannot apply science into dbz ( if you want that then explain me how a time machine fits in a capsule lol ) , they can pack their ki's and not destroy their surroundings whether you like it or not.
