King has made you so desperate lmfao. In the canon manga, King is lucky to be alive as Raidsuit Sanji almost shoved his head straight up Queen’s ass hole (which Marco later did actually)
Anything in Katakuri’s arsenal would easily kill King who is roughly Who’s Who level. A jellybean to the head would kill him quite easily. Marco could’ve defeated King 1v1 (Marco almost defeated King and Queen at the same time) and Katakuri’s arsenal is way above that of Marco.
King having AdCoC doesn’t matter, he can’t land a hit on Katakuri, nor can he react to any of Kuri’s attacks given that he can’t even react to Zolo.
