Marvel had the Glob, Skywald had the Heap, Warren Publications had Marvin the Dead-Thing. There was the Bog Beast at Atlas Comics and the Monster in the Muck at Charlton, while Gold Key Comics offered the Lurker in the Swamp, and the Beast of the Bayou.
As bizarre as it sounds, there was actually something of a vogue in early to mid ’70s funny-books for human corpses emerging from the murk, walking the earth shrouded in goo, and getting involved in other people’s problems. If these stories teach us anything, it’s that some things just refuse to die, especially the propensity for comic book writers to copy off each other.
Honestly, the fact that even one of these lunatic ’70s swamp monster characters managed to survive through the decades as the star of a superhero comic is hard to believe, and yet we find ourselves blessed with two of them: DC Comics’ Swamp Thing, and Marvel Comics’ Man-Thing. It just goes to show what you can achieve, when you put an infinite number of monkeys in charge of your pop culture.
