Swamp Thing, a fictional character, is a plant elemental in the DC Comics Universe originally created by Len Wein and Berni Wrightson. He first appeared in House of Secrets #92 (July 1971) in a stand-alone horror story set in the early 20th century (plotted by Wein and drawn by Wrightson). The Swamp Thing was then reprised in his own series, set in the contemporary world and in the general DC continuity. The character is a humanoid mass of vegetable matter who fights to protect his swamp home, the environment in general, and humanity from various supernatural or terrorist threats.
