Where you get this(don't tell me novel, it is non canon). Kaido was not the WSC during Oden battle...
Kaido is a man right?
A male?
Or no?
Whitebeard title doesn't say "World strongest human", it says world strongest man/male...
And Kaido is a man/male...
He never revealed Oden to be stronger.
Oden so far has nothing to be even named as Whitebeard when it come to powerlvl.
Fact is that Whitebeard gained his title by top tiers and the narrator.
Fact is that he never lost his title.
If someone(Kaido/Mihawk) would ve stronger than Primebeard, one of them would have the title.
The fact no one got it, shows you that the narrator had Primebeard over Kaido/Mihawk and any other character two years ago(pre timeskip).
This includes Shanks and co too(Dragon).
No one surpassed Primebeard, they might now, but so far we didn't got a new replace for Whitebeard title.
As i said, Whitebeard holds the record, no one yet surpassed that record.
I get it from Higurashi saying that he is the Embodiment of Might 10 years after God Valley.
I get it from King telling Kaido to remain the strongest.
I get it from Oden saying that if he cannot beat him nobody else will be able to either.
So yes, Kaido was WSC during the battle against Oden and even 8 years before that.
During battle with Oden, Kaido is 39 years old which is around the beginning of prime for many characters, such as Shanks.
Kaido is not a human and thus disqualified from WSM and thus a superior title is attached to him.
It's not about male and female but species, Kaido's
creature should be enough hint that it isnt about genders.
He did reveal Oden as stronger when he said that Oden's Nittoryu is the greatest there is, that nobody else will be able to beat Kaido and when he said that Kaido's expectations were surpassed while thinking of Oden to be as mighty as Roger and Whitebeard and finally, when he decided to decorate only Oden among Kaido's top 5 with the best feat in the world, a scar on Kaido.
Fact is that he still carried his title despite not deserving it anymore so you have to figure out why...
No, because Kaido and Mihawk arent in the spotlight in pre-TS, that's what you dont get. Hype doesnt work that way.
The fact that Oda doesnt place anyone flat out above WB in pre-TS shows you that he wants to hype him up at that point in story.
However, then comes post-TS, a part of the story where Whitebeard is irrelevant and someone else needs the same treatment and gets even superior title. That's the era when narrator himself says that a mother is even stronger than Kaido, picking him as the highest praise for a fan's mother.
In the present, Whitebeard was weaker than all of them, Mihawk, Kaido, Dragon and Shanks.
However, it was focus on Whitebeard and others are irrelevant at that point so WSM is given to him despite not being WSM then.
Bro legit thinks Oda wants to keep a guy long dead as the strongest... Do you really think that's how you write a story?
It is really simple, there are 3 parts of the story - Pre-TS, post-TS and Final Saga. Each part focuses on one of the 3 WS title holders as the strongest of the era. And I can tell you one thing for certain, the order goes from weakest to strongest, not the other way around.
There is no record, never has been. WSS>WSC>WSM, you will understand this before the story ends.
