if nappa gets a ki blast in he may win.. however with food honor i dont see that happening anytime soon.
idk i always saw dragon ball characters having ridiculous energy output and energy resist. however they havent shown much for actual muscle strenght. and they dont seem that durable against actual punches or kicks. i can tell some instances:
-vegeta getting damaged by rocks big rocks but nothing mountain sized.
-goku only being able to lift 40 tons on base form and this goku is thousands of times stronger than nappa. if his energy output were as good as his strenght he would be able to lift planet earth and even more.
-gohan finding hard to carry the Z sword which shouldnt weight more than 500 tons.
if my theory is true then the attacks of toriko should be able to damage and kill nappa
in those instances toriko characters are wayy above dragon ball characters and that's why i think they can damage them. sani can reflect away almost 100 million tons. it might sound funny and incredible but if the gets gohan with hair marionette he wouldnt be able to move even on sjj2.
I think the point that you're missing is that brute strength doesn't equal striking power in dragonball. There are multiple instances of this being the case. Vegeta with a swat deflected Zarbon's attack which would at the least be island level+. Goku drop kicked Freeza with enough force to shatter through two islands and cause the whole battle field for few mile radius to tremble violently. This is easily class 100+ striking power. Freeza deflected with a kick an attack that would at the least destroy a moon or small planet. SSJ3 Goku deflected a blast with a hammer fist that destroyed 1/10th of the planet. Also if lifting strength meant so much then why didn't Piccolo and Vegeta one-shot Goku when they both went huge and hit him? Clearly brute strength isn't as important a stat in dragonball as it is in say comics.
Dragonball is also not the only one where this is the case. Kenshin Himura I don't think is even a class 100 pounder really and yet he is able to match blades with guys like Hajime Saito and Makoto Shishio. Two guys as strong or stronger than Sanosuke Sagara who wields a blade that weighs 300 pounds with ease. Why? Because Kenshin uses his own Kenki or swordsman ki that increases the striking force of his blade. There are probably plenty of other examples in other mangas where this is the case but I hope my point is clear enough already. These guys focus their Ki behind their blows. It's not just about bench press.
