I didnt ask for your opinion of the scar. Manga has said that nothing else has damaged Kaido's body that much.
Crying and downplaying it cant help your cause, Wessy-chan.
I will trust more what I see than any translation out there - that's how I stay right aka Luffy isnt on his last legs. He was actually fresh, lol.
Or do you wanna say he can fight better and more on his last legs than when he is fresh? Silly, Wessy-chan... Use common sense.
Luffy's aCoC usage was literally identical to Kaido's. There is no mystery behind it, you either coat yourself in it or you dont.
Not a single knockout has affected Luffy, in fact, he only benefited from them. You would know if you paid attention, lol.
