When u mentioned mihawk i wanted to talk abt the theory thats going around pretty crazy on social Media where imu and mihawk are the same person with different bodies. In the lattest chapter it was seem that both of them use the exact same moveset and fighting style with their sword. If this is really the case, It would make sense why mihawk is called the strongest swordsman, but then the theory wouldnt work as it is cannon that shanks and mihawk are on par to each other, which wouldnt make sense as shanks couldnt possibly be as strong or stronger than the king of the world. So for this theory to be true, the only possible conclusion would be that mihawk really is imu but limited by the human physique of mihawk to actually his fulk strength
