When CoC users first manifest the ability, they usually perform the clumsy, uncontrolled fodder knockout technique, but Zoro’s first unconscious use of CoC was strong enough to damage Kaido. That’s a whole new level of CoC we haven’t seen yet, and is fitting for the character whose ambition is to make even heaven hear his name.
The thing with people first should understand is:
When CoC ever get combinated in attacks?
Guys like Luffy who have high lvl CoC attack Kaido so manytimes, when Kaido ever made a comment about their CoC?
Can someone tell me when Kaido ever hype a CoC attack? He literally was shocked when he see Zoro performing a CoC attack, he already get cut by Zoro but he didn´t comment anything, with means Ashura is the source of this CoC.
As example Zoro is someone who see manytimes the power of CoC, he even respond to Brook via saying he didn´t have CoC, but here with Ashura he himself even don´t know it since it is really rare with not everyone pose to have such a power. Because that Kaido make firsttime a comment after taking a hit about CoC, because it impressed him a lot.
Zoro has something really rare, ofc he don´t know it byself since he never see such a CoC lvl.
It make Ashura a adv CoC manifest power based ability, only Kaido who probably see such shit in new world would make a comment about it. In case where we learn about adv CoC, this was Oda directly hint that Zoro has such a power too.
