It kinda doesn't lol. Like, Oda draws 3 chapters advance. You telling me he didn't think to show Kuzan having acoc or even regular coc even though he was about to draw fucking Coby having acoc the very next chapter?
This is why I think it's just Coby hype and not coc lol.
Oda can't have sunken THAT far right?
Logically, Coby getting AdCoC doesn't make sense.
We might see a lot regular uncontrolled CoC burst like what happened at MF with Luffy
So, I really don't think coby got AdCOc...this would be the worst asspull in the series and would shit on haki system for ever.
So if coby really got coc then it's normal CoC awakening out of anger and emotions running high with everyone around him getting destroyed like at MF with luffy
