Prometheus

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!

Aight hear me out, you people might be thinking how Brook is gonna defeat a Yonko. Well, if you think about it, Big Mom's main strengths are her homies, which are Zeus, Prometheus, and Napoleon, BUT, they are homies made from souls, despite them being souls from Big Mom herself. If you watched the anime, you should've seen the scene that Brook released "Soul King aura" and killed the homies. Now, what if Brook unleashes his power and is able to overcome Big Mom's special homes. If he does then Big Mom's best advantage over pretty much any competent enemy is lost.
