Except for brook for some reason

Brook is a skeleton, so he's light enough to use his ice abilities to frozen the water beneath him for a while. I don't know, it's just a guess.

No he’s fast enough to walk on water. The water doesn’t freeze under him.

I'm almost sure that's impossible but whatever okay

Bro Oda has confirmed it. And it’s easily possible it’s One Piece. If Brook weighs nothing he is light enough to run on water.

Doesn’t the ocean in some sense enable your devil fruit? That’s why they use sea prism stone handcuffs on logias

Bro is watching two piece…

The sea disables devil fruit abilities, likewise with sea prism stone handcuffs (which disable all fruit abilities not just logias). So if a shark fruit was made and the user tried to swim with it, they’d immediately be forced out of their transformation and into base form where they would then begin to drown.

@L725 I wouldn't be so sharp regarding the interval until sea can force someone out of zoan form. Warcury might and might not have a devil fruit, but we've seen him maintain transformation inside the sea. So the way the sea affects devil fruits powers depends on durability. Jack was also shown surviving in the water as a fishman.

I need to rephrase, typically the rules surrounding devil fruit users and being pacified by water requires a roughly 50% body submersion. Otherwise the user is fully capable of sustaining themselves at knee or leg depth but they do become more lethargic. Warcury is far less than 50% submerged and I think he understands that, that’s why he’s staying in shallower water (or paddling a bit), however it’s pretty clear he’s suffering from lethargy as well, as I don’t think he’d necessarily take that hit from the iron giant if his observation haki was working at full strength. Jack survived in the water because breathing is a passive action and fish men can breathe underwater. Being in water for a DF user means that passive actions such as breathing, thinking, etc.. continue and that’s why Jack is capable of surviving underwater.

Oda wrote a whole piece about how this works but essentially once a certain % (1/3rd I think) of your body is below the waves you cannot physically move and basically become like an anchor or wrench tossed in water. Interestingly enough Oda does specify moving water aka waves doesn’t take away your abilities or weaken you. So apparently that’s part of why Brooke can run on water without becoming weak or losing his powers, because normally any still water like a pool, pond, or even a puddle should at least weaken you a little bit. So in short it’s simply not possible to get into a floating position on the ocean without first submerging yourself below the waves at which point you become paralysed and sink anyway

This was also an important point in the debate over whether or not it would be worth it to feed a ship a DF, since according to the explanation given by Oda as long as enough of the ship is above the waves the ship shouldn’t sink or become weaker
