I was actually pumped up during Azrael DDK that perhaps it was JPV making his grand return but alas that wasnt meant to be. While I haven't read the new Azrael series, I really can't comment on just how different the backstory is from the actual Azrael. Nevertheless, its quite annoying to expect such a change without a proper send-off or "Whatever happened to...". I would personally have loved it if JPV was given more page-time in the Blackest Night, perhaps even being in the "Blackest Night Batman" mini-series. It would have been a major story and one I thought should have happened. Regardless of which, if comic editors are going to do returns, then at least give returns their due. It did feel cheap that a guy like JPV that had so much exposure in the 90s and his own series would just get just about a page on Blackest Night, and not even be that meaningful.
 
Eradicator is another return that hasn't been done well. He was last seen prior to Infinite Crisis, and returned post-New Krypton/War of the Supermen arc. Wouldn't he have been a major character during the actual NK story arc? Or for that matter, are his appearances in the Outsiders noteworthy enough? I would personally have loved to see Eradicator with the remaining survivors or New Krypton or something, but that doesnt seem likely after what happened in Action Comics 901
 

I'd like to see Toxin to return from comic Limbo. It makes no sense to create interesting character - police officer + non-evil symbiote, and then to forget about him.

I don't mind bringing back characters that have died.  Most definitely I WANT all the dead Guardians back protecting our Galaxy.  It is a shame Marvel wiped them all out and ended the series.  Marvel you suck!   
 
I'd also like to see Knockout in this next Secret Six book come back.  I don't think it is going to happen though, I think it is too obvious for Scandal to save her, and if Simone is anything it is NOT obvious.

Oh, I wouldn't worry about it too much... No interesting character or group stays dead forever in the Marvel Universe... I believe Mar'vell stayed dead the longest, but I also believe he was the first Marvel super hero to die, so he died at a time that death actually MEANT dead....  I'm actually thinking of starting a thread that asks the question, "Which marvel super hero has died and STAYED dead?"

@TheShame:  yes. Phobos was the best part of Secret Warriors.
