Actually he's called 100 beast Kaido because of the fact that his crew of hundreds are all devil zoan fruit users.They most likely became this way because of the artificial smile that Kaido was sold by Don flamingo. Also when he is being referenced in the manga he has many zoan beasts drawn in the background. He's definitely a zoan himself most likely a lion.
