A guy with 30 broken bones and who was already pushing himself above 100% ( Acc. to Law) scarred the WSC just like it's nothing. And you are calling it his best attack? I just pity you. Had he not stopped hakai and saved their asses , they all would have been done by now except ZORO. When Zoro was cutting Prometheus that
coward kaido attacked Zoro from behind, didn't he? He was just afraid of going 1 on 1 with Zoro because he knew the result.
And btw Zoro > Yamato >> Luffy
