Re: Wolverine claws or healing powers? Video
I don't think there's a definitive way to kill Wolverine. His healing factor [I believe] isn't as powerful as Deadpool's, though. First, you have to get through his Adamantium skeleton, which is hard, obviously. You would have to super heat it, and drain it from his body, and how are you going to do this? F*ck if I know.
And then, you'd have to deal with his healing power. Cut his head off? Suffocate him? Blow him up? Who knows. It can be done, we just don't know how.
There's only one true way to kill Wolverine.
Stop putting him in comics.
