thumb| The fictional character Swamp Thing has appeared in five comic book series to date, including several specials, and has crossed over into other DC Comics titles. The series found immense popularity upon its 1970s debut and during the mid-late 1980s under Alan Moore, Steve Bissette, and John Totleben. These eras were met with high critical praise and numerous awards. However, over the years, Swamp Thing comics have suffered from low sales which have resulted in numerous series cancellations and revivals.
