What did Kaido was talking about the “color of the supreme king” towards Zoro? How can Prometheus swim since he’s made out of fire? That doesn’t make a lick of sense to me!
I think is because prometheus is a homie and the water only cause him to slow down and for zoro that wil be explained later in the anime,
EDIT: I did some research and is just a plothole of the anime (the prometheus thing)
What do you think?
