Zoro is in full cope mode because he realises Mihawk is a chump. Big man in East Blue but a mere Yonko commander in the New World. Sad.
Imagine pulling up everywhere with your fleet with your entire crew and bullying on one admiral by himself or bullying on kaido and King and then mihawk alone calls you pathetic trash in front of your entire crew.
Imagine being pure swordsman yet never having haki strong enough to make black blade
Imagine finding out uonko title is so pathetic mihawk can make literal clown a yonko
