It's probably not an Dragon.

There is a second guy, working with Kaido, who betrayed Wano-Kingdom. It's their Shogun. It would make more sense for him to have, that kind of Devil Fruit.



1. Kiemon showed hate toward dragons, and claimed that he wants to kill them, but absolute fear of Kaido. If Kaido was truly a dragon, he would not shown great signs of fear. When you hunt a lion, you should not fear to face it.

He on other hand, he could hate Shogun for betraying his kingdom.



2. Kaido is based upon mongolian invadors. Mongolian culture did not include dragons, unlike Japanese/Chinese culture.

In Japanese culture, dragons are signs of royalty, which links dragons to Shoguns.



Kaido's Devil Fruit is definately Zoan type, but since our mythology, past and our imagination includes creatures of all sorts, it would be impossible to guess, what he ate.
