Base CoC is not used for anything fight related LMFAOO. The fuck are you even on about. Literally zero mentions, implication or feats of it.
And sorry, Zoro before King was already significantly above most commanders on rooftop. The mere fact you called someone who casually chopped Kaido's scales on top of overpowering his attack, blocked strongest attack in OP history momentarily, and while being half dead outdid Kaido in CQC skirmish on top of scarring him for life a... vet life.
If that's vet level, then the fodder who got crushed by drunk, base Kaido must be weaker than Nami.
Rooftop Zoro had feats and portrayal Katakuri. King outdoes that even more.
Actually, I'm not even going to baby you here. You bitch about things and insult others but that quote above shows how agenda driven you are. Calling Zoro vet level after the insantiy showed on rooftop which even left Kaido and BM stunned on multiple occasions.
It's funny to see you cry and cope with the chapter, though. King beats Katakuri in every aspect from portrayal to feats by a MILE.
