The "World's Strongest Creature", Full Analysis
This is a post analysing just the portrayal of Kaido as the "WSC" and why I think Oda has left room for this to be false. I am not looking at feats because the series has not ended and only 2 top tiers have gone all out onscreen, so we don't know if his feats are strongest material. I am not arguing that Kaido is not the strongest, but that it is possible and that the portrayal doesn't back it up.
Kaido's "title" vs Whitebeard's and Mihawk's
Kaido's title is "Kaido of the Beasts" or "Kaido, King of the Beasts", but the narrator went on to say that people say Kaido is the "World's Strongest Creature". In the Japanese and the translation, the narrator directly states that Whitebeard and Mihawk are the world's strongest man and swordsman respectively.
Compare this to Kaido, where the narrator doesn't, and states it indirectly, as something people say, so it's not certain the narrator agrees.
The title is presented as something the narrator heard and chose to parrot, a rumor. So, this title is substantially less credible than Whitebeard's and Mihawk's.
Outside of the narrator, there's also nothing backing up the title at this point in the series chronologically. Whitebeard had his duels with Roger and the hype of Marineford along with the power to destroy the world; Mihawk had his duels with Shanks and being the target of Zoro's dream, which leaves Oda no choice but to make him worthy of the title. Kaido has nothing but defeating Gecko Moria and being the scrub of Rocks' crew. This fits the notion that Kaido was just the subject of rumors based on his appearance, race and bounty, not necessarily strength, which were spread by NPCs in the One Piece world. They obviously don't know anything concrete about the world's strongest.
Common counterarguments
Killer's opinion doesn't matter. The only other pirates he had fought at that point were the Red Hair Pirates excluding Shanks. And since he lost to both them and Kaido, he doesn't know their full capabilities. So, at best, this shows that Kaido > Beckman, but it's more likely he thinks Kaido is stronger and heard the rumors.
Zoro saying Kaido is the strongest
Zoro's opinion doesn't matter. The reasons have been left as an exercise to the reader.
This is comparing apples to oranges. It attempts to frame Kaido's title as being as definitive as Roger's Pirate King title, just because they were both called that by people, and because Roger's is rock solid. That would be fair if Roger's was just given in that panel and parroted by a bunch of other people like Kaido's, but that is far from the case. Roger's is a made up title that was given to him because he found the One Piece, with a lot more evidence of it being true. It is tied to Luffy finding the One Piece, which is the premise of the entire series. It was stated in the very first chapter, and again in Oden's flashback. I am sure I can't even think of all the evidence for it. Kaido's is a strength title stating that he is the strongest creature, but there is no justification anywhere.
All titles are rumors, or made up by the people within the verse. Kaido's title doesn't hold any less legitimacy than everybody else's.
Sure, I don't think titles are that concrete by themselves. But if Whitebeard's and Mihawk's titles are rumors or made up, so aren't reliable, then Kaido's are even worse, as argued above.
Kaido's opinion doesn't matter. The only top tiers alive he has met are Shanks and Big Mom. There isn't any conclusive evidence that he is above Shanks and he probably hasn't met Imu, Dragon or Mihawk. Don Krieg said he was the strongest man, even after losing his fleet to Mihawk, but he isn't the strongest.
Editor #56 is easily swayed by rumors. It is not in the volume release.
This is in no way confirmation of Kaido being the WSC, it just takes people knowing about the rumors of Kaido being the strongest to hype up P.N. Star Fairy's mother in a joking way. Also, it is in volume 83, so Oda still wants to hype Kaido as the strongest, without outright confirming it. He's not going to downplay Kaido in an obvious way.
I looked at the Japanese version of volume 95, and there wasn't a blurb, so this was written by some random guy for the english release.
Luffy’s Vivre Card, apparently
How did Kaido become renowned as the strongest? Who knows. And doesn't confirm that Kaido is the strongest. Vivre cards aren't reliable anyway.
Why would the rumor, multiple characters and multiple supplementary sources be wrong
Kaido is effectively the antagonist of most of the post-timeskip from Punk Hazard to Wano. But, he was defeated before the final saga. He needed some hype to make sure readers weren't disappointed with spending that long on him, when there might be stronger characters in the future. So, he was given the rumors and hype, but with subtle reasons that they are not definitive.
All in all, Kaido's portrayal as the "World's Strongest Creature" is shaky, so don't be surprised if he gets powercrept in the future. And don't overrate him because of that portrayal.
