Wounded and beaten Samurai recovered within 2/4 chapters.
But Zoro can't do the same? With Law/Marco & even chopper around?
Same Zoro that went on to fight fishmen after the nasty wound Mihawk gave him? Yeah okay...
Kaidos commanders and other pirate subordinates haven't been defeated yet.
So I doubt Luffy will 'defeat' Kaido before Zoro can recover, or before his commanders have been defeated.
Big Mom's pirates haven't technically entered the fray either.
Plus Kaido is lifting an Island, so he's technically not at full strength, regardless of his hybrid form.
Now correct me if I'm wrong, but has Kaido ever (since the beginning of the story) used CoA to defend against attacks?
Because as far as I know, he's relied on his superior physiology to help him.
Let's see how luffy deals with Kaido thats actually defending against his attacks.
Long live ZKK though 😏
