lol, I just meant people who only have a personality on the internet, and that personality is a regurgitated, typical "internet" archetype. Concluding that they are probably very nice, yet socially awkward people. This obviously isn't necessarily my opinion, but you get the imagery I'm setting up here.
Yeah, Wolverine does tend to be... very good at coming back to life. :x Happened in Avengers vs X-Men too. He was completely destroyed by the Phoenix Force and ~miraculously~ recovered. Again, it's just the writers illustrating the devastating "power" of a force and the protagonist's abilities to overcome and triumph, be it physical or mental. That's the wonderful thing about comics! Take Avengers vs X-Men, for example. That was the climax of a story that had been occurring since the 50s. Have you seen the X-Men movies? Because they hint to an AvX movie (in my opinion) which seems to correspond suspiciously well with the release of the Avengers movie (although, I think they're producing a second movie but idk). Anyway, unless the writers specifically deem something as otherwise, everything is canon. Everything is being carried over from when Wolverine was a sketch on the back of a paper plate. It's all relevant.
As for the biological end of it, well, it's a mixed bag. Wolverine always had mutant DNA which provided him with claws and supernatural regenerative abilities. I'm fairly confident that they released an arc about Wolverine and his powers actually, so you can always pick that up if you want to learn more! From what I understand, and according to how it is explained, Wolverine can be reduced to a skeleton, much like he was in that atomic explosion. So long as some of his DNA remains intact and he's not in contact with the Muramasa blade, that mutant DNA produces and replicates all of his cells as they originally existed. It's also been mentioned that, since Wolverine had been reduced to a skeleton (or injured to an absurd extent) sooo many times, his regenerative abilities have adapted to perform faster and better than other mutants with the same skill. So yeah, Logan is pretty broken but hey, he's the main character. :p And in my opinion, he's way less broken than some superheros. I mean, Xavier has died, like, died died, at least four times now. But, Wolverine is only broken because he's in a universe of mostly non-broken characters (save Hope, but she doesn't even know she's broken). Unlike Thor, who is literally a God. Like.. omnipresent, all powerful, lightning bolts from the sky, God. But, when paired against his brother Loki, Thor seems rather tame due to his tendencies towards order. But, pair up Thor and Wolverine.. and there's no doubt Wolverine would "lose" (not die-- just be beaten to submission, which is like the same thing lol). At the end of the day though, all the characters, good or evil, will keep coming back. That's why we played those games as children. They were too much fun and told too good of a story to just let them die.
Topping my personal list of broken heroes is definitely Superman though. Easily. It's like... DC just gave him powers as they thought of them. :/ It partially the reason DC began the New 52. Everything just got so messy that they literally started over. It was like... 700+ issues of Green Lantern just vanished. Hal Jordan is dead. The New 52 wasn't really a good move for some characters, but it really needed to happen for others. Batman got a total revamp and it's one of the best current Batman comics in existence. They're on like issue 16 or 17 right now-- so it's not too late if you want to jump in. ;) I highly recommend it!
Well, Spiderman is dead. Like, Peter Parker is gone. Dead. Died. Like actually for real. ;( Now a bunch of "avanging Spiderman" books have come out and they even did a "Spidermen" run with Ultimate Spiderman (Miles Morales) and Peter Parker. But what's hard to wrap your head around is the fact that there is like.. a billion universes in the comic world. Peter Parker only died in the most important universe. He's still alive in the past and whenever they see fit to revive him for storyline purposes. But the singular universe that was The Amazing Spiderman, no longer contains Peter Parker. u_u;; I'm not even a huge Spiderman fan, but it's still sad.
