Bog Swamp Demon

The Bog Swamp Demon is a swamp monster that first appeared in the pages of Teenage Mutant Ninja Turtles comic book series. His adventures are chronicled in issues #4 through #12 of Volume 2 of the Mirage Studios title. He is one of the many comic book swamp creatures from various publishers based on the archetype established by Theodore Sturgeon's "It!"

Bog fought a horde of demons summoned by a coven of harpy-witch sisters living in the swamp. The demons took human form to do their dirty deeds but, being a demon himself, Bog saw them for what they really were and promptly dispatched them. Bog killed one of the witch sister's thus prompting the remaining two to conjure help from hell. The demon Bathym answered their call only to be killed by Bog who lured him to hallowed ground, a swamp-side cemetery, where he impaled the demon beast on a tombstone.

For some reason the story segments are out of sequence in the Teenage Mutant Ninja Turtles comic books. A paragraph on the inside front cover of Teenage Mutant Ninja Turtles volume 2 number ten addresses this but offers no explanation. Part one of Bog begins in Teenage Mutant Ninja Turtles volume 2 number six then skips an issue and resumes with issue eight but omits Bog part 2, printing instead Bog installment number 3. Bog part two then appears in Teenage Mutant Ninja Turtles volume 2 number ten instead of issue nine. Things get back in order with Teenage Mutant Ninja Turtles volume 2 number eleven which prints Bog part four and finally the Bog Swamp Demon story concludes in issue number twelve of the Teenage Mutant Ninja Turtles volume 2 title.
