See, my thinking is, and grizzly bear with me, is that Wolverine can only die if he gets hit with a blast that destroys his skeleton along with vital organs, or if he gets 'beaten to death' while his healing factor is completely overloaded
Both include him not being immortal.
Are you feeling me wilderness(extra 's' like you're a snake)?
that blast would have to destroy every cell as it has been mentioned that logan could regenerate from a single cell; does dos doomsday have this kind of energy projection? he's definately not going to get beaten to death with his current HF.
I see what you're saying though, I'm just not certain doomsday can achieve the former.
Regenerating from a single cell could have to do with his immortality though... plus the part where it's never happened.
His healing factor can still be overloaded, and Doomsday certainly has the power to overload it. It's just a matter of what we think can theoretically kill the Wolverine
actually, i think he did regen from nothing but a charred adamantium skeleon when it was shown that jean grey phoenix can bring him back from nothing/0 cells. at least, that's what it looked like.
