Lol its been extrm diff fight because fist = fist. Also wci luffy were weak af than rooftops wgs. Both kata luffy df are similer even shanks will one shot kata. Luffy wont win easly by using fist. Hawkings vs kata debatable. Even killer got insane speed. I dont need to remind you kaido speed...
yes when he uses ashura it already confirms he had coc even before luffy.
when they realize Three Thousand Worlds also using coc which used against mihawk
he is the second character who used coc in entire series after shanks :steef::finally:
