Moving fast enough for light refraction to slow down isn't a superpower...it's that the normal human body can't handle that speed that makes it impossible. We turn into messy globs way before then. However, if you'd actually notice what I was saying before, since there's no way to strip him of chi the same principle would indirectly apply- since afterimages aren't a byproduct of the martial arts so much as light refraction no longer continuing with a moving object and Goku without the chi to do that would be dead if we were talking about a living Goku the point of 'realworld physics' would still be moot. It is the application of chi in unnatural ways that conflicts with physics and not the indirect application of what's already there. Strip both combatants of this to equalize them and there would be no point to the fight. You would have the "first Shinto human effect", two people barely breathing and slumped onto the ground with most of their body withered and/ or shutting down.
You don't get it do you? Goku without chi means he's dead. Superman without chi means he's dead. Chi is needed for existence. In it's most basic form all it represents is the breath of life within us all. Without it this battle can't happen. If you're going to say any feat of strength done with the exertion of chi in the body can't be used as it's defined as a 'superpower' in your eyes and make a chi-less Goku you end up with Dead Superman vs. Dead Goku. If you would so kindly do your research into the principle you'd find that everything from breathing to excresion of waste from the body is connected to the healthy (or, at times, unhealthy) flow of chi through channels believed to be throughout the body. Hence the premise of acupuncture- restoration of the basic bodily functions. It has nothing to do with 'focus' when you move or grip something. Focusing chi to the point that you do something extraordinary that normally could never be done by the limitations of matter (and yes, at the height of human potential Son Goku's early feats are paltry) is when it can be properly designated as a 'superpower'. Thus, the Kamehameha could not be used- it's an visually outward extension of chi, something that has never been scientifically proven or recorded. But if you're so adamant of Goku having no chi whatsoever, here's a screenshot from the anime at a point where he had no chi (or what you've convoluted into a 'superpower'):
You know, just because I'm a fan doesn't mean that I can't debate rationally. Just because I see things differently from you doesn't mean I have some ravenous agenda. I can see Superman winning in a fight with the Hulk and a Pre-Crisis Superman beating most all DBZ-related characters outside of Super Vegetto. It's just under the circumstances debated in this topic (both combatants stripped of what both sides consider to be 'superpowers') that I see a different outcome. If you've notice, I've yet to post 'goku wins cuz he's the strongest' or that you're ignorant for not agreeing.
I actually came into this topic with the naivete that this was a logical conversation on two characters and not a flame war.
Umm...hate to rain on your parade, but if Goku had no powers (which in this case would mean the inability to focus his chi) it doesn't mean he would lose. Sure, he wouldn't be able to channel his chi into techniques. But knowing how to defend yourself isn't a superpower. Even if you stripped him of all chi-related techniques he still moves so fast he leaves afterimages behind him. Without their superpowers Kal-El is a normal man and Goku is a skilled fighter.
