[X-Men] Can Wolverine drown, or die of thirst or starvation?
gpt
I don't know about starvation or thirst,  but drowning is a common theme in his comics. 

He killed his son by drowning him.  He's been nearly drowned several times but someone managed to stop it. 

For the most part drowning wolverine is the only way to really kill him.  You just have to keep him down there long enough for everything to give out.

(The newest movie does differ, but we don't know how long he was down there.  Maybe it wasn't too long.  In the comics, he dies from drowning and it's the one real way to do it)
