Nah portrayal it’s clear roger and primebeard are above him, bro oda and characters were putting oldbeard above kaido that should tell you something
Eh no. You should dive more deeper into the contents
You can't scale Roger/WB against Kaido by portrayal because they are from different era and have different legacy.
According to your portrayal logic, Kaido and Big mom are equal too
The people of one piece world said bet on Kaido 1v1 supposedly even during Whitebeard was alive, and the one piece world called him strongest living thing.
So portrayal logic says Kaido > any being right??
Pretty sure Old WB would eventually fall in the hands of other Yonko in the future even if MF war doesn't happen. WB maintain his title because no one has or have the urge to take him, whether he is getting older and weaker with health issues, he will still remain at the top in the eyes of ppl who "used to know" about him decades ago, if no one takes him down, just like the so-called weakest Yonko by fans reign supreme in her throne for decades
Kaido is the only one who try to attack WB. Which is interesting
And Shanks interrupted, why did Shanks do that??
He want to save Kaido because WB would kill him(lol) "OR" that Kaido is major threat to WB
You pick what makes more logical sense lol
