Debuting on Halloween October 31st 1990, Swamp Thing ony ran for five episodes, failing to build on the popularity on the movie and television show that came before it.
Scientist Alec Holland invents a growth substance that could end world hunger, but a plantation owner obsessed with immortality tries to steal it and causes an accident that turns Alec into a human-plant mutant, protector of the bayou.
In the cartoon series Swamp Thing (Len Carlson) mainly battles Anton Arcane (Don Francks) as it is Arcane who was responsible for Alec Holland’s transformation into the Swamp Thing. Arcane is backed by his gang of Un-Men: Dr. Deemo (Errol Slue), Weedkiller (Joe Matheson), and Skinman (Gordon Masten).
Swamp Thing is aided in his adventures by Tomahawk (Harvey Atkin), a Native American who was a soldier in the American Revolution, Bayou Jack (Philip Akin) a Vietnam veteran, and young boys Delbert (Jonathan Potts) and J.T. (Richard Yearwood).
Another interesting ally is Abigail Arcane (Paulina Gillis), the stepdaughter of Anton Arcane. Abigail hopes to help her friend Swamp Thing become human again.
Through the five episodes we see adventures involving NASA, the Amazon rainforest, Native American burial grounds, lost caverns, and New Orleans!
In 1990, Kenner produced a line of Swamp Thing action figures with vehicles & playsets that served as a direct counterpart to the animated series.
