I remember reading that he was sent to Purgatory, but does that count? Many people in the Marvel Universe have died and come back at one point or another, but has one the most violent and reckless heroes truely died and come back?

" @damyria990: I think he died in the Days of Future Past story line.  Other than that, Magneto almost killed him in Fatal Attractions. "

@Edamame: I remember reading both of those,too. I mean has he died in the 616 Universe? "

He's definitely died once during the Fall of Mutants saga, although he and his fellow X-Men were almost immediately resurrected by Roma for theri heroism. Maybe he was also dead for a moment in the 11th Uncanny X-Men Annual, but it's rather uncertain.

Aside from all the times when the entire universe has been destroyed and restored, and the mentioned Uncanny #227 he also died in Wolverine #175

" He also died during the original Secret Wars. But he and the other heroes were resurrected thanks to the healer chick and some of Battleworld's advanced tech. "

Logan can't die...Marvel treats him like a god. Give Spider-Man some love
