Lets hope he is cuz i wanna see him fight someone.
if he is it wont be mihawk
most likely has conqueror haki given his title
a black blade which zoro still wants to forge
an ephithet emphasising keen observation perhaps
and the person who trained zoro in armament.
you can argue everything zoro has atm he has much better.
zoro is still a bit behind
one more opponent before he might be set imo.
