Mihawk is thee greatest swordsman on one piece he also is one of only 3people never harmed in the entire one piece series saying he wouldn't stand a chance against shanks who only has one arm(when he fought a shanks with too arms) just because he gained the rank of yonko doesn't mean his power jumped to unreachable levels
well if you go by your logic then shanks shouoldnt be a yonkou because of his lost arm.
Be realistic if he really was weak then he woulnt be a yonkou.
Thats why Law is targeing Kaido even after Luffy wanted to go after shanks because he knows shanks is stronger.
Im not saying Mihawk is weak, but dont diss shanks by saying that MIhawk can beat him..
And just becasue he doesnt get hurt doesnt mean anything. Hes only appeared like twice and fought a weak newbie zoro. And in the war none of the warlords were hurt. therefoe invalid arguement
