Swamp Thing is a superhero and antihero appearing in American comic books published by DC Comics. Created by writer Len Wein and artist Bernie Wrightson, the Swamp Thing has had several different incarnations throughout his publication. The character first appeared in House of Secrets #92 in a stand-alone horror story set in the early 20th century. The character found perhaps its greatest popularity during the original 1970s Wein/Wrightson run and in the mid-late 1980s during a highly acclaimed run under Alan Moore, Stephen Bissette, and John Totleben. Swamp Thing would also go on to become one of the staples of the Justice League Dark, a team featuring magical superheroes.
