At present with what we know about Deadpool, based on the 2016 movie version, we know he has regenerative abilities.

Can he drown? Can he survive drowning?

  • By surviving you mean not dying or dying and not coming back to life? Because he likely can die from this, but would likely come back to life.

  • @Durakken, if he can come back to life, is there anything canon that says he can?

  • Nothing said, but his regen ability is based on the idea of cell longevity and cells regenerating (perniciously so) so long as they can respirate. Cells stay alive after a person dies and deadpool has even longer than normal longevity so it's assumed that as long as 1 cell that's still alive can get oxygen that cell can regen and repair any damage and revive him...though it might take outside intervention to get the oxygen to the cells due to the organs that do that not working at that moment.

    I don't know a way to answer this definitively but based on the evidence, if he can survive being impaled through the chest and then burned alive and crushed under a building then the chances are he would survive drowning (which is simply another way of depriving the brain of oxygen and if that could kill him he would have died in the fire).

  • @Durakken Which still makes me wonder whether you can get two Deadpools by cutting him into two halves?

In the movie universe (X-Men Universe), Deadpool got his powers from the Weapon X Program which is based on Wolverine's mutant powers.

Although Wade Wilson doesn't have a skeleton made of adamantium, he has super healing powers we have seen in Wolverine.

In X-Men: Days of Future Past, we saw Wolverine drowning under water (at the end of the movie).

enter image description here

When he was taken out of the water. Wolverine was left trapped there for an unknown period of time until Mystique, disguised as Major William Stryker, has him rescued and takes custody of him for an unknown reason.

This shows that Weapon X gene gives you abilities of surviving drowning or suffocation. Other than that, there aren't any comic references for Deadpool's healing ability in this area.

  • I agree, as far as I know, if you drown, the main problem is, that your cells begin to die, because they get no oxygen anymore, when enough cells, especially the brain cells die, you.. well... die. But if you are able to regenerate cells, even new cells, as we saw it when growing back his hand. It would be likely that he dies, but his cells still regenerate, as long as there is one living cell left. Commented Jul 25, 2016 at 7:55

When you drown your lungs are flood with water, there's no way to get oxygen from water and, as a consequence, your cells cannot get oxygen and start to decay.

When brain cells stays too much time without oxygen, your brain suffers damage, usually grave damage that cannot be repaired. At some point, essential life functions get stopped. Your heart stops, your brain activity stops, you die.

But your body cells will still be alive for a certain period, not every cell in the body perish in the same moment. Your body starts to rot on a slow decay (quite accelerated underwater).

In the case of Deadpool it's difficult to say what could happen. My wild guess is that the brain damage he could suffer would get repaired almost instantly, this means he never dies completely. His blood will become toxic for his organism, as there wouldn't be enough oxygen in it (his heart won't stop, but the absence of oxygen would make it impossible to renew blood in the lungs). Massive organ damage to kidneys and liver will probably follow, again, to be almost instantly repaired.

As there is no oxygen to carry to muscular cells, probably he won't be able to make physical efforts, eventually it's possible that he becomes completely inmobile, but also it's probably that he loses any bit of consciousness a lot before.

As the organ damage that the loss of oxygen produces will probably be slower than the rate at which his body regenerates, drowning him will only have the effect to put him in a stand by state, where he becomes incapacitated and unconscious, but alive.

If he is somehow dragged to surface and reanimated (at least breath would need to be reseted) he probably get conscious and fully functional quite fast.


The difficult part would be subdoing him. Once you accomplish that you'd have to toss him into the ocean with sufficient weight to make sure he couldn't resurface. Sinking deep enough would add pressure and ensure he couldn't escape. Also his organs would crush and possibly his bones. Lack of oxygen and he passes out his lungs fill with water and he dies. Either the pressure or lack of oxygen kills him. Not sure which happens first. Either way all his cells decay and no more regeneration no more deadpool

    Is this entirely speculation or do you have any evidence you can [edot] in?
