User blog comment:Monkey.D.Sammy/Kaido the Strongest creature in the world/@comment-5729687-20130609053259

When Law said that Kaidou is the strongest creature in the world it give me an immediate impression that Kaidou is really gigantic and also a non human. Since in the World of OP we've seen talking bear, talking lion, talking toys, Giants, etc it is possible that Kaidou is not a human at all.

I'm also gonna say that he is the biggest of the 4 yonkou. He may be even bigger than Oars, Oars Jr or even Sanjuan Wolf.

Also Doflamingo is somehow afraid of Kaidou so it shows that his strength and also his viciousness.

DF I have no idea, I wouldn't be surpise if he did not even have one and he could have just pure strength.
