User blog comment:Kaido King of the Beasts/Why Does Doflamingo Carry a Gun? - And Other Stupid Questions/@comment-24638955-20141125183600

The reason he uses a gun on someone is because when he uses his gun is to make stand out he is executing someone as a World Noble/Celestial Dragon (I know he technically isn't but for Doflamingo point of view he is still) rather than as a pirate which then he would use his DF powers or other means.

Sakazuki likes dogs because when bad trained they bite people not based on if they follow justice or not, they just bite.

Señor Pink has Peter Pan and the Chunibyo sindrome so there is that he thinks he is harboiled but deep inside his true self is a very weak and softboiled man.

Kaido is stupid because he has to be an animal in stereoids so don't expect it to use the brain to much.

Those bananas tried to eat the Crocodiles, as the bananas are the apex predators of Alabasta and are still digesting them alive. It is just the bananas going bananas.
