But I don't see anything impressive about Akainu beating Aokiji, we know that since the introduction of Whitebeard he is capable of beating any higher level with the exception of Kaidou and he doesn't even need to duel for 10 days against them to prove it, we know that Whitebeard wins Aokiji, We know that since the introduction of Kaidou, that Kaidou beats Aokiji, but in Marineford we knew that Akainu could beat Aokiji? No, so Akainu still needs to prove that he can beat opponent in which Oda already said that Whitebeard and Kaidou are winning, same for Mihawk, Mihawk according to his title beats Fujitora, but is Akainu able to beat Fujitora? He needs to prove it, because he simply doesn't have statements, titles that make him capable, as is the case with Kaidou, Wb and Mihawk.
Another example:
Can WB defeat Dragon? He can, and for that he doesn't even need to fight him, Oda through his title is validating the fact that WB > Dragon.
Can Kaidou defeat Dragon? Yes, Oda through Kaidou's title and statements is validating the fact that Kaidou
> Dragon.
But can Akainu beat Dragon? No, he needs to prove he can by fighting him. LMAO
Defeating another top tier is no better than titles and declarations, especially when it comes to globally scoped titles.
Defeated a higher level? Okay, what about the rest of the other higher levels?
