Doffy casually humiliating and disregarding a guy who:
Fought prime Scopper Gaban for multiple days, didn't lose
Shanks didn't ask to recruit(like how Blackbeard didn't want to recruit the guy stronger then him in the movie)
Akoiji had to cheat against
Made Mihawk give up on fighting against the Yonko, something that gives him a PTSD attack 2 years later
Like it or not, the only characters we can be sure stronger then Doffy are Kaido, Big Mom, Aramaki and Borsalino
