An idiot? Says the guy using text abbreviation? maby ur actooly the idiot, dood.
Anyway, WB was the worlds strongest MAN making him the strongest among only MEN. Then there's Kaido who is the strongest among all living creatures on the planet. That encompasses the entire planet and all its life as Oda described. Even if Kaido himself is a man that doesn't take away from the statement. There could be multiple creatures in the OP world that are > WB. If Kaido (who came about after WB had gained his title of WSM) were to be stronger than these beasts who were stronger than the WSM why would his title of strongest creature on earth be a paradox? The man is humongous with horns and a body made of freaking diamond (figuratively speaking) and leaps from Sky islands without a scratch. How is at all strange to label the him the strongest creature on Earth even if he is technically a man? To be able to deny what is a direct statement from Oda himself you must have some sort of executive power at SJ and are able to influence the story. I can't think of any other way for you to be able to contradict the author himself.
i think u mabey loosen it dood. or are u an ideot lol?
