And once again, I ask you, why are you putting Shanks and BM on the same pedestal when Shanks is the second oldest character in the series and is tied to the MC far deeper than any other character including his own crew?
Such a shitty argument to make, like if Oda didnt create a full chapter illustrating how he won without beating her (stole her RPs, Defeated 2 commanders, escaped her territory had 3 factions under her revolt, etc). He was even called the 5th Emperor because of it. Newsflash, this was chapter 903, and it highlights the exact argument people make about Big Mom.
