Alan Moore's run on Swamp Thing was memorable on many levels. As well as reinventing a rather lackluster take on the titular character and changing the rules of the game completely in "The Anatomy Lesson", he also introduced John Constantine and Swamp Thing's true nature as an embodiment of the plantlife of the world. Constantine would put Swamp Thing through many trials and tests to make him become used to his new existence and the true extent of his powers.
He also did some truly awesome horror stories... This is one that lingers with me, partly because of the hook for the main character, and partly because of the amazing art from Steve Bissette and John Totleben (And Ron Randall too, according to Mr Bisssette himself)
Say hello to the nice people Swamp Thing!

"Hi nice people!"
I was never able to take American's referring to "the Boogeyman" seriously. As a kid in the 1970's it was a dance, and how could a monster be named after a fun, if silly-looking, dance? In the UK there is another name for such monsters, a much less pleasant sounding word, so from Swamp Thing 44, I present...
( Bogeymen! )
