In the entire canon anime, we only saw Luffy (and the crew), Ace, and Buggy, as well as Jack, as the DF users who experienced drowning. (we can include smoker, for a while) I want Kaido to get drowned or BM :( :(
That only shows how strong they are. Nobody can still bring them near the sea to drown. I guess.
Technically Jack isn't drowning.
They must have drown but some guys like Aokiiji can just freeze the water body and make it a ground to walk on.
What if Aokiji was knocked out and throws in the water, do you think the water will freeze
their power are worthless when they are under water. I think he'll be weakened before he can use his ability.
there is that evidence that luffy tried to swim up before totally drowning: that time frame could possibly be used by aokiji to freeze the water
BM will get drowned because she is a DF user but for Kaido, I'm not sure about him.
What do you think?
