Been re-reading a lot of Alan Moore because of the movie, and just got through his six volumes of Swamp Thing. In volume 5, Swamp Thing's body is destroyed, and he's blocked from entering the green, by the machinations of Lex Luthor. ST's consciousness is thus flung across the universe, and ends up on a (seemingly) barren world where he reforms himself out of blue corral.
The entire issue is his inner monologue as he creates a second Swamp Thing for companionship, then an entire town of his old friends. I couldn't help but feel that, seeing as this issue ("My Blue Heaven") was published in 1987, this picked up Dr. Manhattan's story where Watchmen left off. In fact, seeing as Alan Moore's run on ST started about 1-2 years before Watchmen was published, I can't help but think of Swamp Thing as a proto-Dr. Manhattan now.
As well, re-read Moore's Supreme run and am now reading Tom Strong for the first time. The Supreme stuff is All-Star Superman before Grant Morrison. It's provocative how Moore mentioned in an interview that he felt guilty for turning the superhero genre grim & gritty, and has been attempting to bring it back to its silver age roots since the mid-90s or so (aside from the occasional From Hell and League of Extraordinary Gentlemen). I very much enjoy his America's Best Comics stuff, it's a lot of fun.
The old stuff, along with late 80's/early 90's Hellblazer, Books of Magic and Sandman makes me miss the days when Vertigo housed a small corner of the DCU that, although separate, would occasionally bleed over into the main whole. Moore's Swamp Thing has Constantine on the Monitor's space station during the Crisis! I liked outsider characters commenting on the silliness of the genre as a whole. These days Hellblazer is the only old tier Vertigo left, with nary a Zatanna or Phantom Stranger appearance in sight.
