Hero Overview

After all the suffering... and horror... I have witnessed... it is good... to see so many people... in one place... having a good time...
~ Swamp Thing
The swamp, is my world. It is who I am... it is what I am. I was once a man. I know the evil men do. Do not bring your evil here, I warn you. Beware the wrath of... Swamp Thing!
~ Swamp Thing (Narrated in the 1990 TV Series)
"Good? Bad? I care little for humanity. But I do care... when my swamp burns!"
~ Swamp Thing in Injustice 2

Swamp Thing is a fictional superhero in the DC Universe and comics. He is elemental-swamp monster that often absorbs the memories of many people, most notably Dr. Alec Holland. He is also the partner of John Constantine and Animal Man

Bernie Wrightson and Lein Wein created Alex Olsen and Alec Holland's Swamp Thing, Alan More and Stan Woch created Albert Höllerer's Swamp Thing, Doug Wheeler and Pat Broderick created Tefé Holland's Swamp Thing, Mike Hoffman and Wheeler created Allan Hallman's Swamp Thing, Jon J. Muth created Aaron Hayley's Swamp Thing, as Scott Snyder and Yanick Paquette created Calbraith A.H. Rogers' Swamp Thing.

The character first appeared in House of Secrets # 92 in July of 1971, as Alec Holland's Swamp Thing first appeared in Swamp Thing # 1 in October-November of 1972.


Once, there was a man. A man named Alec Holland.

A brilliant scientist, Holland was perfecting a formula designed to turn deserts bloated with forests... until a bomb planted by enemies destroyed his lab, lighting him on fire. In desperation, Alec fled into the swamp, hoping to put the flames out. Though he was too late to save his own life, the Parliament of Trees transferred his memories into a new body made entirely of vegetation. Initially thinking himself to be merely transformed into a "muck-encrusted mockery of a man", Alec sought to return to his human form... only to discover the truth years later.

Now, Alec protects the swamp from those who would harm both it and its inhabitants. Do NOT bring your evil into the swamp... or else, you'll face the wrath of... the Swamp Thing!


  • Chlorylkinesis:
  • Florapathy:
  • Shapeshifting:
  • Body Formation:
  • Regeneration:
  • Elemental Control: The Swamp Thing has complete mastery over all forms of plant life and can command vegetative matter to do his bidding. Through this power, he is in constant communication with the very essence of the Earth and serves as the Plant Elemental for the entire planet.
  • Superhuman Strength: The Swamp Thing's strength level is directly tied to his connection to the Earth. Occupying his most commonly used body, the Swamp Thing is capable of lifting volumes of mass many times greater than his own body weight. With additional power supplied to him by The Green, his ultimate strength level is nearly incalculable.
  • Chlorokinesis: The ability to commune with plant life and to varying degrees control its growth and form. Summon forth vines to entangle or snare, and so on. A master of this ability can manipulate the microscopic algae inside of a person's body and use it to attack them from the inside out.
  • Self-Sustenance: The ability to nourish oneself, typically via an external energy source. In Swamp Thing's case, likely through a form of photosynthesis.

  • The Swamp Thing television series first aired on USA Network from 1990 to 1993. The series was filmed in the brand-new Universal Studios Florida facilities and soundstages with Dick Durock reprising the role of the Swamp Thing.

Factory.
  • DiC Entertainment's Swamp Thing animated series debuted on Fox Kids in April 1991, with Len Carlson providing the voice of the Swamp Thing. Anton Arcane was the series' main villain, along with his three Un-Men. The animation style followed a trend similar to Troma's Toxic Crusaders. The program only lasted five episodes and is often considered a miniseries. Neither of these incarnations were highly successful critically or commercially, but the live-action series developed a cult following. A moderate collection of merchandise was produced for the animated series, including an action figure line by Kenner and video games by THQ.
  • The Swamp Thing made a small cameo appearance in the Justice League episode "Comfort and Joy". He was seen at a cantina.

  • The Swamp Thing's human name was mentioned by NBC who released a photo for the TV series Constantine which shows Constantine's calling card number Constantine, Master of the Dark Arts at 404-248-7182 and When you dial the number, a recording says, "Hello, you've reached John Constantine. And that's John Constantine. If you're looking for Alec Holland, try the bloody swamp."[17] It was rumored that the Swamp Thing would appear in a future episode, but the show was cancelled.

  • A live-action series based on the Swamp Thing and produced by James Wan debuted in 2019 on the DC Universe streaming service with Derek Mears portraying the Swamp Thing in a "physical costume" rather than CGI, while Alec Holland will be portrayed by Andy Bean. The pilot was written by Mark Verheiden and Gary Dauberman and directed by Len Wiseman.


  • The Swamp Thing's expansion into media outside of comic books began with his first eponymous film in 1982. Directed by Wes Craven, it starred actor/stuntman Dick Durock as the Swamp Thing. A sequel, The Return of Swamp Thing, was produced in 1989. This was much lower in budget and met with significantly less success than its predecessor.[citation needed] The film series rejected the popular Alan Moore revision of the Swamp Thing's origin and portrayed the Swamp Thing with his original origin as a man turned into a plant-like entity.[citation needed] They also heavily featured Anton Arcane, who now became the man responsible for causing Alec Holland's transformation into the Swamp Thing.
