Oda had more than 300 chapters to build up kaido and he failed miserably, kaido was a nobody before wano, even in wano he's still a nobody, the only interesting thing about him is the rocks flashback and vegapunk hype.
Kaido's oni race is so lame and uninteresting, his racial superiority argument is so generic, his lack of aggression and bloodlust is pathetic for a supposedly very powerful brute.
Such a shame that he had the most badass introduction in the series, the narrator saying "the strong lives and the weak dies, this is the only rule of this world" then it turned out that it's all a big lie, it's understandable why kaido left kid, killer and hawkins alive, but why didn't he kill the rest of their fodder crew members, literally no one died from kid's crew.
Mf defeated the scabbards, and he just sat there, just for him to fight kin'emon again half an hour later and suspiciously killing him.
I read entire series of similar length that had masterfully written characters than one piece.
