[Theory] Post-Dressrosa Arc

[Ryuma720]

I have a feeling Kaido's crew will make a appearance in DressRosa
Then we get a appearance of Kaido pissed that the smile is no more (after Luffy and the gang destroy the factory)

Kaido one-hit kills Flamingo !

 

[Dr Strangelove]

That is certainly most likely.
