What do you guys think his devil fruit could be??
He might not have a devil fruit he may just be RAW!!!
If he did it would clearly be a mythical beast from hell.
GumGum Leo - if Kaido doesn't eaten any DF but people call him Beast because of his personality, power and shit and people feared him as the Strongest Creature alive, then He sure as hell is way too Badass. But why would he gather such many zoan devil fruit users in the first place? is it just for collections or sort of shit like that? or is it because he is a zoan devil fruit eater himself?
Kaido's DF might be the Thypon. Cause it has wings and a Lower Torso of a serpent and a probably a body of a man... why is he a thypon? because as you can remember people says that 'among all the living, be it Land Sea or Air, he said to be the strongest pirate alive'.
Either some sort of immortality devil fruit or a special devil fruit that allowed him to consume 1000 different smiles which is why he is called "Thousand Beasts Kaido"
