No i am not relying on only character dialogue. It seems you can't read. I told you various things like Ace novel, Databooks, Sbs, and dialogue. When did i said Oda gave Kaido a title like WB? Learn how to actually read. I said people called WB the strongest (sengoku and marines).
Yeah, i don't believe Kaido statements because i have more knowledge then Kaido. I know Zoro the main character of this story so i know the future. Just like when BM and Kaido say they can be PK and shit. They don't knkw they are in a story and Luffy the destine Winner and Zoro the destine best swordsman. When it comes to knowing who the strongest currently in the story, characters can know this because it won't change anything.
