I'm not saying Injury messes wth portrayal. If it did then Zoro would have the worst portrayal in the crew.
I'm just saying its quite curious that Oda has specifically not shown Mihawk take damage. And Mihawk is actually part of the story and actually does things all the way back since East blue unlike Dragon and he still hasn't even gotten scratches.
I hhave a feeling that he probably never will until Zoro or until we get a flashback of his earlier days.
So Oden knows already that the birth of Joy Boy is 20 years based on the laughtale expedition and that is Luffy senpai! if Oden can not defeat Kaido at the point someone in the future will come to wano and will defeat kaido that is why Toki is crying while reading Oden notes. Toki is not the traitor because as a samurai with 2 kids she needs to be calm all the time despite the situation
Feel sorry to old hug who is the first owner of Mane Mane no Mi because she was being executed by kaido itself and the reason for kaido is always suicidal because of this chapter!
