Swamp Thing is an American animated television series based on the DC Comics character, Swamp Thing. Debuting April 20, 1991 on FOX, it lasted only five episodes. The short-lived series, produced by DiC Entertainment, corresponded with Kenner's Swamp Thing action figure collection released the year prior.
Like previous film incarnations of Swamp Thing, the animated series rejects the popular Alan Moore revision of Swamp Thing's origin and portrays him with his original origin as a man turned into a plant-like entity. Anton Arcane takes the role of the main villain responsible for Alec Holland's transformation into Swamp Thing. Arcade is backed by his gang of Un-Men: Dr. Deemo, Weedkiller, and Skinman. Swamp Thing also has two friends named Tomahawk and Bayou Jack. Tomahawk is Native American not to be confused with the DC/Vertigo character, Thomas Hawk, who was a soldier in the American Revolution rescued by Native Americans. Bayou Jack is a Vietnam veteran.
Similar to Troma's Toxic Crusaders, the animation style of Swamp Thing follows the trend of goofy, horror anti-heroes made for the children. Spoofing Chip Taylor's "Wild Thing," the opening theme plays "Swamp Thing! ...You are amazing!" The series also bears an environmentally conscious side also noted in many of its contemporaries.
Swamp Thing was apparently turned down by CBS, leading it its mid-season debut on FOX. Despite the show's limited number of episodes, NBC featured it during Chip and Pepper's Cartoon Madness in fall 1991, and the Sci-Fi Channel would syndicate it years later. USA Network and the UK's Children's Channel also re-aired Swamp Thing in the 1990s. Most recent was its stint on Toon Disney in the 2000s.
Ever since the Swamp Thing animated series, the title character's only animated appearances have been two small cameos in Justice League and Justice League Unlimited. He first appears at a cantina in "Comfort and Joy." In the premiere episode of JLU, "Initiation," an unnamed creature aboard the Justice League Watchtower also looks remarkably similar to Swamp Thing.
