His myth is based on a Carp turning a Dragon. I fail to see where the Carp comes into play.
I see where you are coming from.
But that rule has been established before though.
Ox Ox fruit Model: Giraffe is a Giraffe and not an Ox, same way as how Fish Fish fruit Model: Seiryuu is a Seiryuu and not a Fish.
Plus Momonosuke also instantly turned into a Dragon no?
I think you can say Kaidou's buff Hybrid form maybe Awakening but other than that, I dont see answers.
All it took was a simple line from Oda but he fucked up.
Kaidou's still the Strongest though.
