Writer/creator JM DeMatteis didn't get to finish his Man-Thing
storyline with Mr. Termineus due to early cancellation and Marvel refusing to even publish the completed final 2 issues of the story (sales were REALLY bad). Some years later, while working on DC's 'The Spectre" volume 4, a villain named Monsieur Stigmonius is introduced who, both in characterization and design, holds strong similarities to Mr. Termineus. It is entirely likely that DeMatteis did this to finallyi get some of his unpublished ideas with the character out of his system.
