The Swamp Thing is a fictional character in American comic books published by DC Comics. A humanoid/plant elemental creature, created by writer Len Wein and artist Bernie Wrightson, the Swamp Thing has had several humanoid or monster incarnations in various different storylines. The character first appeared in House of Secrets #92 (July 1971) in a stand-alone horror story set in the early 20th century. The character then returned in a solo series, set in the contemporary world and in the general DC continuity. The character is a swamp monster that resembles an anthropomorphic mound of vegetable matter, and fights to protect his swamp home, the environment in general, and humanity from various supernatural or terrorist threats.
The character found perhaps its greatest popularity during the 1970s and early 1990s. Outside of an extensive comic book history, the Swamp Thing has inspired two theatrical films, two live-action televisions series in 1990 and 2019 and a five-part animated series, among other media. IGN ranked him 28th in the "Top 100 Comic Book Heroes" list. He appeared in his first live adaptation in the 1982 film. Dick Durock portrayed the Swamp Thing, while Ray Wise played Alec Holland. Durock reprised the role in the sequel film The Return of Swamp Thing along with playing Holland. Durock reprised the role again in the 1990 television series. The Swamp Thing was performed by Derek Mears with Andy Bean playing his human form of Alec Holland in the television series for DC Universe.
Concept and creation
Len Wein came up with the idea for the character while riding a subway in Queens. He later recalled, "I didn't have a title for it, so I kept referring to it as 'that swamp thing I'm working on.' And that's how it got its name!" Bernie Wrightson designed the character's visual image, using a rough sketch by Wein as a guideline.
Len Wein was the writer for the first 13 issues, before David Michelinie and Gerry Conway finished up the series. Burgeoning horror artist Bernie Wrightson drew the first 10 issues of the series, while Nestor Redondo drew a further 13 issues, the last issue being drawn by Fred Carrillo. The original creative team worked closely together; Wrightson recalled that during story conferences, Wein would walk around the office acting out all of the parts. The Swamp Thing fought against evil as he sought the men who murdered his wife and caused his monstrous transformation, as well as searching for a means to transform back into his human form.
The Swamp Thing has since fought many villains. Though they only met twice during the first series, the mad scientist Anton Arcane (with his obsession with gaining immortality) became the Swamp Thing's nemesis, even as the Swamp Thing developed a close bond with Arcane's niece Abigail Arcane. Arcane was aided by his nightmarish army of Un-Men and the Patchwork Man, alias Arcane's brother Gregori Arcane, who after a land mine explosion was rebuilt as a Frankenstein Monster-type creature by his brother. Also involved in the conflict was the Swamp Thing's close friend-turned-enemy Lt. Matthew Joseph Cable, a federal agent who originally mistakenly believed the Swamp Thing to be responsible for the deaths of Alec and Linda Holland.
As sales figures plummeted towards the end of the series, the writers attempted to revive interest by introducing fantastical creatures, aliens, and even Alec Holland's brother, Edward (a character that was never referred to again by later writers) into the picture.
The last two issues saw the Swamp Thing transformed back into Alec Holland and having to fight one last menace as an ordinary human. The series was cancelled and a blurb for an upcoming encounter with Hawkman led nowhere (however, the story was later told in Swamp Thing (vol. 2) #58).
In 1982, DC Comics revived the Swamp Thing series, attempting to capitalize on the summer 1982 release of the Wes Craven film of the same name. A revival had been planned for 1978, but was a victim of the DC Implosion. The new series, called The Saga of the Swamp Thing, featured an adaptation of the Craven movie in its first annual. Now written by Martin Pasko, the book loosely picked up after the Swamp Thing's guest appearances in Challengers of the Unknown #81-87, DC Comics Presents #8, and The Brave and the Bold #172, with the character wandering around the swamps of Louisiana seen as an urban legend and feared by locals. Pasko's main arc depicted the Swamp Thing roaming the globe, trying to stop a young girl (and the possible Anti-Christ) named Karen Clancy from destroying the world.
When Pasko had to give up work on the title due to increasing television commitments, editor Len Wein assigned the title to British writer Alan Moore. When Karen Berger took over as editor, she gave Moore free rein to revamp the title and the character as he saw fit. Moore reconfigured the Swamp Thing's origin to make him a true monster, as opposed to a human transformed into a monster. In his first issue, he swept aside most of the supporting cast that Pasko had introduced in his year-and-a-half run as writer and brought the Sunderland Corporation to the forefront, as they hunted the Swamp Thing down and "killed" him in a hail of bullets. The subsequent investigation revealed that the Swamp Thing was not Alec Holland transformed into a plant, but actually a wholly plant-based entity created upon the death of Alec Holland, having somehow absorbed duplicates of Holland's consciousness and memories into himself. He is described as "a plant that thought it was Alec Holland, a plant that was trying its level best to be Alec Holland". This is explained as a result of the plant matter of the swamp absorbing Holland's bio-restorative formula, with the Swamp Thing's appearance being the plants' attempt to duplicate Holland's human form. This revelation resulted in the Swamp Thing suffering a temporary mental breakdown and identity crisis, but he eventually re-asserted himself in time to stop the latest scheme of the Floronic Man.
Moore would later reveal, in an attempt to connect the original one-off Swamp Thing story from House of Secrets #92 to the main Swamp Thing canon, that there had been dozens, perhaps hundreds, of Swamp Things since the dawn of humanity, and that all versions of the creature were designated defenders of the Parliament of Trees, an elemental community which rules a dimension known as "the Green" that connects all plant life on Earth. Moore's Swamp Thing broadened the scope of the series to include ecological and spiritual concerns while retaining its horror-fantasy roots. In issue #37, Moore formally introduced the character of John Constantine the Hellblazer as a magician/con artist who would lead the Swamp Thing on the "American Gothic" storyline. Alan Moore also introduced the concept of the DC characters Cain and Abel being the mystical reincarnations of the Biblical Cain and Abel caught in an endless cycle of murder and resurrection.
With issue #65, regular penciler Rick Veitch took over from Moore and began scripting the series, continuing the story in a roughly similar vein for 24 more issues. Veitch's term ended in 1989 due to a widely publicized creative dispute, when DC refused to publish issue #88 because of the use of Jesus Christ as a character, despite having previously approved the script in which the Swamp Thing is a cupbearer who offers Jesus water when he calls for it from the cross. The series was handed to Doug Wheeler, who made the cup that the Shining Knight believed to be the Holy Grail to be a cup used in a religious ceremony by a Neanderthal tribe that was about to be wiped out by Cro-Magnons, in the published version of issue #88. Beginning in issue #90, Wheeler reintroduced Matango, a character that Stephen Bissette had introduced in Swamp Thing Annual #4.
After a period of high creative turnover, in 1991 DC sought to revive interest in Swamp Thing by bringing horror writer Nancy A. Collins on board to write the series. Starting with Swamp Thing Annual #6, Collins moved on to write Swamp Thing (vol. 2) #110–138, dramatically overhauling the series by restoring the pre-Alan Moore tone and incorporating a new set of supporting cast members into the book. Collins resurrected Anton Arcane, along with the Sunderland Corporation, as foils for the Swamp Thing. Her stories tended to be ecologically based and at one point featured giant killer flowers.
With issue #140 (March 1994), the title was handed over to Grant Morrison for a four-issue story arc, co-written by the then-unknown Mark Millar. As Collins had destroyed the status quo of the series, Morrison sought to shake the book up with a four-part storyline which had the Swamp Thing plunged into a nightmarish dreamworld scenario where he was split into two separate beings: Alec Holland and the Swamp Thing, which was now a mindless being of pure destruction. Millar then took over from Morrison with issue #144, and launched what was initially conceived as an ambitious 25-part storyline where the Swamp Thing would be forced to go upon a series of trials against rival elemental forces. Millar brought the series to a close with issue #171 in a finale where the Swamp Thing becomes the master of all elemental forces, including the planet.
Written by Brian K. Vaughan and drawn by Roger Petersen and Giuseppe Camuncoli in 2001, the third Swamp Thing series focused on the daughter of the Swamp Thing, Tefé Holland. Even though she was chronologically 11–12, the series had Tefé aged into the body of an 18-year-old with a mindwipe orchestrated by the Swamp Thing, Constantine and Abby in order to try to control her darker impulses, brought about by her exposure to the Parliament of Trees. Due to the circumstances under which she was conceived, the Swamp Thing, possessing John Constantine, was not aware that he was given a blood transfusion by a demon. She held power over both plants and flesh.
Believing herself to be a normal human girl named Mary who had miraculously recovered from cancer three years prior, she rediscovers her powers and identity when she finds her boyfriend and best friend betraying her on prom night. In a moment of anger, her powers manifest and she kills them both. Tefé then fakes her own death and embarks on a series of misadventures that take her across the country, and ultimately to Africa, in search of a mythical "Tree of Knowledge".
During this series, it seems that the Swamp Thing and Abigail have reunited as lovers and are living in their old home in the Louisiana swamps outside Houma. The home in which they live more closely resembles the one that the Swamp Thing constructs for Abigail during the Moore run than the home in which they dwell during the Collins run. In a confrontation with Tefé, the Swamp Thing explains that he has cut himself off from the Green and there seems to be no trace of the god-like powers he acquired from the Parliaments of Air, Waves, Stone or Flames during the Millar run. Also, Vaughan's Swamp Thing does not seem to have been divorced from the humanity of his Alec Holland self. The disconnection between these two entities becomes a plot point in Volume 4.
A fourth series began in 2004, with writers Andy Diggle (#1–6), Will Pfeifer (#7–8) and Joshua Dysart (#9–29). In this latest series, the Swamp Thing is reverted to his plant-based Earth elemental status after the first storyline, and he attempts to live an "eventless" life in the Louisiana swamps. Tefé, likewise, is rendered powerless and mortal. Issue #29 was intended to be the final issue of the fourth volume, which was cancelled due to low sales numbers.
Return to the DC Universe
The conclusion of the crossover event Brightest Day revealed that the Swamp Thing had become corrupted by the personality of the villain Nekron in the wake of the Blackest Night crossover event. The Swamp Thing now believed himself to be Nekron, similar to how he had once believed himself to be Alec Holland. The Swamp Thing went on a rampage in Star City, ultimately seeking to destroy all life on Earth. The Entity within the White Lantern used several heroes, including Hawkman, Hawkgirl, Firestorm, the Martian Manhunter, Aquaman and Deadman to slow the rampage and to construct a new Swamp Thing based on the body of Alec Holland. Instead of merely thinking that it was Holland, this version of the Swamp Thing would actually be him. The new Swamp Thing defeated and killed the corrupted and original Swamp Thing. The Swamp Thing then restored life to natural areas around the world and declared that those who hurt the Green would face his wrath. He also restored Aquaman, Firestorm, Hawkman, and the Martian Manhunter to normal. The book ended with the Swamp Thing killing several businessmen who engaged in deliberate, illegal polluting activities.
Brightest Day Aftermath: The Search for the Swamp Thing
This three–issue miniseries follows immediately after the events of Brightest Day, and follows the actions of John Constantine as he tries to work out what has changed with the Swamp Thing and track him down, with the assistance of Zatanna, the Batman, and Superman.
DC Comics relaunched Swamp Thing with issue #1 in September 2011 as part of The New 52, with writer Scott Snyder (#1-18 and Annual). Snyder's run concluded with "Rotworld", a crossover event between Swamp Thing, Animal Man and Frankenstein, Agent of S.H.A.D.E. Charles Soule wrote issues #19-40.
A six–issue miniseries written by Len Wein, co-creator of the Swamp Thing, with art by Kelley Jones was released between March and August 2016.
Fictional character biography
Alexander "Alex" Olsen was a talented young scientist in Louisiana in the early 1900s married to a woman named Linda. Alex's assistant, Damian Ridge, was secretly in love with Linda and plotted the death of his friend. He tampered with Olsen's chemicals, killing him in the explosion and dumped his body in the nearby swamp. Ridge used Linda's grief to convince her to marry him, only to one day become confronted with Alex Olsen again, now a risen humanoid pile of vegetable matter. Olsen killed Ridge, but Linda did not recognize him and ran away, leaving Olsen to wander the swamps alone as a monster.
Albert Hollerer is a German airplane pilot who fought in World War II and was shot down over a bog in 1942. In the wake of his death in which he was burned alive, he became the Swamp Thing of that era. For years, he walked the Earth, keeping only a small airplane toy with him as the only memory of his former life. In 1954, the creature finally found peace among the Parliament of Trees.
Alan Hallman was selected by the Parliament of Trees to be the planet's Earth elemental before Alec Holland became the Swamp Thing. He had been a scientist working on a formula to repair damaged crops when the Parliament chose him, and he died in flames—as all Earth elementals must. However, while traversing the Green, he was captured within a creature of the Grey, which broke him down and converted him into fungus and mold. He was recreated as an emissary of the Grey by Matango, who gathered Hallman's consciousness back together in his Chamber of Dreams. With Matango's return from Hell, Alan Hallman was released into the Green to find and capture the Swamp Thing and his daughter Tefé and force them to surrender their individuality to the Grey.
Aaron Hayley is an American soldier in World War II, who was slain and arose as the Swamp Thing. Since there was already an active plant elemental at the time (Albert Höllerer), he was only active as the Swamp Thing for a short time, and soon took his place among the Parliament of Trees.
Calbraith A. H. Rodgers
Calbraith A. H. Rodgers was born in England in 1920. Ever since he was a boy, he had heard whispers from the leaves, the flowers and the trees that something great and terrible would be waiting for him on the other side. Afraid of what would be waiting for him on the other side of death, he enlisted in the Royal Air Force to try and escape the pull of the Green. On May 3, 1942, on his fourth mission as a pilot during World War II, his plane was shot down. Landing in a swamp, the dying Rodgers felt the branches and petals reaching for him, delivering him to his new life as the protector of the Green. By fusing the man with the Green in the final moments of his life, the Swamp Thing was created.
Rodgers served a number of years as the Swamp Thing before taking his place in the Parliament of Trees, the final resting place of his predecessors, where his consciousness would live on as the flesh of his body died. Rodgers would later leave the Parliament of Trees to become the Swamp Thing once again in order to warn Alec Holland of the coming of both the Rot and Sethe, the enemy that the Swamp Thing was born to defend the Green against. Rodgers knew that to remove his consciousness from the Parliament of Trees would mean true death. After delivering his message to Alec and warning him to stay away from Abigail Arcane, he died.
Powers and abilities
In physical form, the Swamp Thing is a chlorokinetic-transmorphic elemental entity; an Avatar of "The Green" (the plane of existence for the hive-mind and life force of all plant life on Earth). The Swamp Thing can inhabit and animate vegetable matter anywhere, including alien plants, even sentient ones, and construct it into a body for himself. As a result, bodily attacks mean little to him, he can easily regrow damaged or severed body parts, and can even transport himself across the globe by leaving his current form, transferring his consciousness to a new form grown from whatever vegetable matter is present in the location that he wishes to reach. He even grew himself a form out of John Constantine's meager tobacco supply on one occasion.
The Swamp Thing is normally human-sized or slightly larger than average, but he can grow bodies much larger. He once used Sequoioideae to grow a body the size of an office block.
The Swamp Thing possesses superhuman strength; however, the Swamp Thing's strength has never been portrayed as prominently as many of his other abilities. DC's The New 52 continuity made several changes, though mostly highlighting previous abilities and a physical look not dissimilar from previous incarnations. The New 52 reboot did bring the Swamp Thing further into the shared universe continuity by placing him permanently in the Justice League Dark team lineup, partnering with many familiar faces like John Constantine, Zatanna and Deadman. The Swamp Thing's powers and abilities make him the true powerhouse of the team. His power limits have yet to be established. He has demonstrated sufficient strength to rip large trees out of the ground with ease and trade blows with the likes of Etrigan the Demon.
The Swamp Thing can control any form of plant life, he can make it bend to his will or accelerate its growth. This control even extends to alien life, as he once cured Superman of an infection caused by exposure to a Kryptonian plant that was driving Superman mad and causing his body to burn out its own power.
After Mark Millar's run, the Swamp Thing had also mastered the elements of Fire, Earth, Water and Air; the Parliaments of each were later killed by the Word, implying that he has retained these abilities and has the power once held by the Parliaments; this has yet to be explained.
The new Swamp Thing (a resurrected Alec Holland) has no power over a White Lantern Power Ring, but he can control all forms of plant life and even grow every kind even if it is unknown to him; he can also grow from any plant life anywhere, dead or alive; this is seen when the Seeder (the Floronic Man now endowed with power by the Parliament of Trees and with his mind splintered as a result of the events of Infinite Crisis) creates a portal to the Moon and banishes him there. However, Holland simply resurrects himself back on Earth from the plants growing on the Seeder's face.

Due to having a past with Constantine he allows them to go unharmed, but warns that he will not be as lenient the next time. The Swamp Thing makes good on his threat near the climax of Year Three, where he appears to aid the Regime against the Insurgency. Poison Ivy is brought in to take him on, though they unite to preserve Earth as the demon Trigon and Mister Mxyzptlk get into an epic fight that threatens to engulf everyone and send them to Hell. As the Flash races to save everyone before it is too late, the Swamp Thing becomes intangible at the last minute and is trapped in Hell.
- In JLA: The Nail, Holland appears as an advisor to the President and Wonder Woman makes reference to her stopping an attempt to steal details of his bio-restorative serum. Holland is apparently killed when the White House is destroyed in an attempt to frame Wonder Woman as an alien invader, averting any possibility that he will serve as the template for the Swamp Thing.
