uuh i think yu out of pure physicial ability would win pretty quickly, like yeon (if your are talking about the weak hero mc) is only able to beat opponents by "studying ahead" and using pressure points and tricks and shit. but yu would jsut sidestep all that by simply being able to use the stance he did against jean and just knock yeon out with a single straight punch. like the first punch that yu landed on jean. its like putting yeon against an adult version of donald nah(or whatever the dudes last name is) who has been training with those baboons from mihawks island that have copied yus techniques....if u get that refrence i applaud u btw
Yu would win hands down as the person said above out of pure physical ability and intellect gray studies the predictable movements of the people around by being in such a toxic environment for so long and even if he was to study up on martial arts he still couldn’t predict not protect himself against YUs super human techniques plus grey probably wouldn’t fight him in the first place because he knows how pick his battles and on another note please remember to support author on webtoon
