Gotta say, and I hope people don't take this the wrong way due to my bias of wanting a true swordsman fight, but IF Zoro and the rest (for now) get fucked up by Kaido and the war starts to get worse for the alliance, I hope that a damaged Zoro has his fight with King.
Yes at this point there's probably zero merit for it, and we also have to see what happens with Sanji/Yamato/Chopper, but it would be awesome if Kaido's right hand became a nuisance at the worst time and Zoro is forced to hold him off because of it.
We'll see, I doubt it's happening but it'd be cool nonetheless to give him a definitive matchup because it'll be pretty obvious that a least for some time, Luffy will hog up a few big moments with Kaido
I'm ready to be flamed now
