To be honest, I always did wonder why Oda went the Sky Island kamikaze swan dive route of "hyping" Kaido considering that this same feat was achieved by Gedatsu hundreds of chapters ago.
Anyway, Kaido has never impressed me as a character.
My first impression of him was that he was going to be a one dimensional meathead that relies on raw intimidation and hype to attempt to make himself memorable.
My impression of him now is that he is a contradictory bitch that talks big but has lost all semblance of the intimidation and false hype that was propping up his empty husk of a character.
By the time the next popularity poll comes round, chances are he will not even be in the Top 30 characters.
Keep in mind that Oda spent over a decade hyping this utter disappointment up. Lel.
