What ways can Wolverine die?

Can he die through drowning and oxygen loss?? Any other ways?

Well, when everything fails, call Bendis

Anything lethal once you remove his healing factor. Otherwise there are sometimes methods that are said to work, but some of these have been survived by him on panel in comics by other writers.

Powerful energy blasts have killed him twice on panel both in future timelines. I doubt he would survive having his head cut off either.

I theorize that any character that can duplicate or copy other characters powers, gained Hank Pym's size changing powers, Blobs powers, Human Torches powers, Ghost Riders powers, Madcap's powers and Hydroman's powers they could turn themselves into a giant and eat Wolverine… then their stomach would be a fiery pit of supernatural liquid flame they could control and it would burn forever, either killing Wolverine or at least preventing him from healing to normal.

Genocide.

Organ removal, suffocation, drowning, brain damage, and anything else that Healing Factors don't really heal.

Anything that can't be healed

If he can't heal from it, then he dies horribly.

Being atomized.

Soul steal?
