No we don't. Specially when Kaido started to talk about JoyBoy and how Luffy didn't could became him. People were even speculating if JoyBoy isn't a title instead of a unique person. We could have Kaido as JoyBoy or even Momo because he was giving orders to Zunesha.
Did you even read fishman Island?
Weve known joyboy was a person
and that his will is carried within a secific person.
it's been VERY obvious that it was luffy.
Kaido stated that ONLY because he thought he just KILLED him by throwing him in the ocean...
Yes he would.
You are simply ignoring how haki blooms in One Piece.
First of all, no one ever used Enma to unlock CoC. Even Oden just learned that after getting beat by Roger.
Second, haki blooms in extreme situation. For Luffy was getting koed by Ragnarok(which sucks since he got defeated) but for Zoro was blocking Hakai which left him in a every bad condition. That's why when he uses Asura against Kaido already has ACoC on it and he was able to scar Kaido.
Asura was not coated in COC...please stop with the headcannon
he clearly awakened it only when he was on his last legs vs King and the sword literally pulled it out of him.
he was literally monologuing about how enma was draining too much haki and then said to enma "ill give you what u want"
after that he learns how to coat COC.
