User blog:Staw-Hat Luffy/About Kaido

After chapter 697 I'm really curious about Kaido's nature.We know almost nothing about him but he is gonna be a major antagonist.So,till now we know What's wrong with that guy??Is he a fishman or maybe does he originate from a Sky Islands?Is he a DF user?And my most important question is Will he fight Doflamingo,or  Doflamingo will retrieve Ceasar?
 * 1) He is NOT a human
 * 2) He isn't patient and he's merciless
 * 3) He is considered the biggest threat in the world
 * 4) He likes power
 * 5) He doesn't value his crewmates(since he will kill Doflamingo if he finds out abut the Punk Hazard incident)
