'''Swamp Thing''' is a [[superhero]] and [[antihero]] appearing in [[American comic books]] published by [[DC Comics]]. Created by writer [[Len Wein]] and artist [[Bernie Wrightson]], the Swamp Thing has had several different incarnations throughout his publication. The character first appeared in ''[[House of Secrets (DC Comics)|House of Secrets]]'' #92 (July 1971) in a stand-alone horror story set in the early 20th century.<ref>{{cite book |last=McAvennie |first=Michael |title=DC Comics Year By Year A Visual Chronicle |publisher=[[Dorling Kindersley]] |year=2010 |isbn=978-0-7566-6742-9 |editor-last=Dolan |editor-first=Hannah |page=146 |chapter=1970s |quote='Swamp Thing' was the name of Len Wein and Bernie Wrightson's turn-of-the-century tale, and its popularity with readers led a modernized version of the character into its own series a year later.}}</ref> The character found perhaps its greatest popularity during the original 1970s Wein/Wrightson run and in the mid-late 1980s during a highly acclaimed run under [[Alan Moore]], [[Stephen Bissette]], and [[John Totleben]]. Swamp Thing would also go on to become one of the staples of the [[Justice League Dark]], a team featuring magical superheroes. 

The character is often depicted as a swamp monster that resembles an anthropomorphic mound of [[vegetable]] matter seeking to protect [[nature]] and humanity from threats of both scientific and supernatural origin. These duties are often an expression of his designation as the '''Avatar of the Green''', an illustrious title depicted as synonymous with both Swamp Thing and makes the character the embodiment of the cosmic energies that gives life to all plant life in the known universe, often dubbed "'''The Green'''". Several incarnations arise from the consciousness of other beings who are selected as the champion of the '''Parliament of Trees''', the guiding and collective consciousness of all plant life, which includes past incarnations of Swamp Thing.<ref name=":1">{{Cite book |last1=Manning |first1=Matthew K. |url=https://books.google.com/books?id=Q2k0EAAAQBAJ |title=The DC Comics Encyclopedia New Edition |last2=Wiacek |first2=Stephen |last3=Scott |first3=Melanie |last4=Jones |first4=Nick |last5=Walker |first5=Landry Q. |date=2021-07-06 |publisher=Penguin |isbn=978-0-7440-5301-2 |language=en}}</ref> Swamp Thing is also often in an elemental conflict with both rivals within the Green (i.e [[Floronic Man]]), rival elemental forces, such as "The Red" (embodies all animal life, including humanity), and most notably "The Rot" or "The Black" (embodies death), with their archnemesis being [[Anton Arcane]]. 

The original version of the character is '''Alexander Olsen''', a scientist who was killed by his assistant vying for the affections of his wife. Returning as a swamp creature, he confronts his assistant and kills him in revenge but his wife runs off, unable to recognize him. He later becomes a local legend in Louisiana.  His successor, [[Alec Holland|'''Alec Holland''']], is the second and most well regarded version of the character. A [[chemist]] who dies following the creation of a scientific formula capable of stimulating plant life in hostile environment to criminal or malevolent elements. Stories vary in his being, sometimes a plant creature believing himself to be Alec possessing his memories while later stories make him the genuine Alec who transforms into the Swamp Thing. This version is also a reluctant ally of John Constantine and a later member of the Justice League Dark, considered a powerhouse among their ranks.<ref name=":6">{{Cite book |last=Tynion |first=James IV |title=Justice League Dark.

In 2021, a new incarnation of Swamp Thing is created. This version is '''Levi Kamei''', a young [[Indian people|Indian]] scientist chosen as the new Swamp Thing at a young age. Descended from a [[tribunal]] connected to the [[Kaziranga National Park|Kaziranga]] wetlands, his powers awaken following a altercation between the community and employers, which also resulted in the death. Following his awakening, various factions seeking to control the new Swamp Thing for their own nefarious agenda.

The character has been adapted from the comics into several forms of media, including feature films, television series, and video games. The character made its live-action debut in the film ''[[Swamp Thing (1982 film)|Swamp Thing]]'' (1982), with [[Dick Durock]] playing the Swamp Thing, while [[Ray Wise]] played [[Alec Holland]]. Durock played both Swamp Thing and Holland in the sequel film ''[[The Return of Swamp Thing]]'' (1989). Durock reprised the role again in the television series ''[[Swamp Thing (1990 TV series)|Swamp Thing]]'' (1990). The Swamp Thing was played by [[Derek Mears]] with [[Andy Bean (actor)|Andy Bean]] playing Alec Holland in the television series ''[[Swamp Thing (2019 TV series)|Swamp Thing]]'' (2019). Another live-action film adaptation, titled ''Swamp Thing'', is in development as an installment of the [[DC Universe (franchise)|DC Universe]] (DCU) media franchise. [[IGN]] ranked him 28th in the Top 100 Comic Book Heroes list.

==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!"<ref name="WeinDaddy" /> Bernie Wrightson designed the character's visual image, using a rough sketch by Wein as a guideline.<ref name="WeinDaddy" />

==Publication history==
{{Main|Swamp Thing (comic book){{!}}''Swamp Thing'' (comic book)}}

===Volume 1===
[[File:Swthing01.jpg|thumb|200px|Cover of ''Swamp Thing'' #1 (October–November 1972), art by [[Bernie Wrightson]]|left]]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.<ref name="WeinDaddy">{{cite journal |last1=Ho |first1=Richard |date=November 2004 |title=Who's Your Daddy?? |journal=Wizard |issue=#140 |pages=68–74 |publisher=[[Wizard Entertainment]] }}</ref> 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 [[Abby Holland (comics)|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 (DC Comics)|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 with issue #24 and a blurb for a 25th issue containing an upcoming encounter with [[Hawkman]] led nowhere. Alec Holland's transformation back into the Swamp Thing was covered in ''Challengers of the Unknown'' #81-87, within which the Swamp Thing is enlisted by the titular team to fight the [[Lovecraftian]] cosmic threat M'nagalah, whom the Swamp Thing had encountered during Wein's run.

===''The Saga of the Swamp Thing'' and Volume 2===
[[File:Swampthingmoore21.jpg|thumb|left|Cover of ''The Saga of the Swamp Thing'' (vol. 2) #21 (February 1984), art by [[Tom Yeates]]]]
In 1982, DC Comics revived the ''Swamp Thing'' series,<ref>Manning, Matthew K. "1980s" in Dolan, p. 197: "Swamp Thing returned to the pages of a new ongoing series, written by Martin Pasko and drawn by artist Tom Yeates".</ref> attempting to capitalize on the summer 1982 release of the [[Wes Craven]] [[Swamp Thing (1982 film)|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 film 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]].<ref>{{Cite journal |last=Watson |first=Dan |date=December 1986 |title=Alan Moore Adds Sin and Drugs to Swamp Thing |url=https://books.google.com/books?id=FL-rqqrDxb8C&pg=PA10 |journal=[[Spin (magazine)|SPIN]] |volume=2 |issue=9 |pages=10 |via=Google Books}}</ref> 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]].

Issue #32 was a strange twist of comedy and tragedy, as the Swamp Thing encounters an alien version of [[Pogo (comic strip)|Pogo]], [[Walt Kelly]]'s character.

Moore would later reveal, in an attempt to connect the original one-off Swamp Thing story from ''[[House of Secrets (DC Comics)|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|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.

''The Saga of the Swamp Thing'' was the first mainstream comic book series to completely abandon the [[Comics Code Authority]]'s approval.<ref>"Comics Code Rejects ''Saga of Swamp Thing'' Story; ''Swamp Thing'' Rejects Code", ''[[The Comics Journal]]'' #93 (September 1984), pp. 12/13.</ref>

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.<ref>"''Swamp Thing'' Cancellation Begets Protest, Media Attention", ''The Comics Journal'' #130 (July 1989), pp. 28–29.</ref><ref>"Rick Veitch Quits ''Swamp Thing''", ''The Comics Journal'' #129 (May 1989), pp. 7–11.</ref> 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-Magnon]]s, 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,<ref>"Swamp Thing Team Leaves", ''The Comics Journal'' #139 (December 1990), p. 16.</ref> 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.<ref>"Nancy Collins: ''Swamp Thing''<nowiki>'</nowiki>s New Scripter Speaks", ''David Anthony Kraft's Comics Interview'' #102 (1991), pp. 4–13.</ref> 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.

===Volume 3===
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 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.

===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 story line, 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===
====''Brightest Day''====
{{See also|Vertigo (DC Comics)#Relationship to 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.<ref>{{cite comic|writer= [[Geoff Johns|Johns, Geoff]]; [[Peter Tomasi|Tomasi, Peter]]|penciller= [[Ivan Reis|Reis, Ivan]]; Prado, Joe|inker= [[Norm Rapmund|Rapmund, Norm]]; Albert, Oclair|story= Rise and Fall|title= [[Brightest Day]]|issue= 23|date= Early June 2011}}</ref> 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 Corps|White Lantern]] used several heroes, including [[Hawkman (Carter Hall)|Hawkman]], [[Hawkgirl]], [[Firestorm (comics)|Firestorm]], the [[Martian Manhunter]], [[Aquaman]] and [[Deadman (DC Comics)|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.<ref>{{cite comic|writer= Johns, Geoff; Tomasi, Peter|penciller= Reis, Ivan; Prado, Joe; [[Patrick Gleason (artist)|Gleason, Patrick]]; [[Ardian Syaf|Syaf, Ardian]]; Clark, Scott|inker= Rapmund, Norm; Cifuentes, Vicente; Albert, Oclair; Nguyen, Tom; Gray, Mick; Irwin, Mark; Beaty, David|story= Brightest Day|title= Brightest Day|issue= 24|date= Late June 2011}}</ref>

=== Past incarnations ===

* '''Allan Hallman''': 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. 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 (DC Comics)|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.

* '''Albert Höllerer''': 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 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.{{efn|This timeline corresponds with the fictional biography and dates of [[Hillman Periodicals]]' character [[Heap (comics)|The Heap]], published 1942–1953.}}

* '''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.

==Powers and abilities==
The Swamp Thing, considered typically the Avatar of the Green, possess the power to control the aforementioned "Green", the cosmic energies in which animates all plant life in the known universe and is often the living embodiment of it. With it, the Swamp Thing possess various powers, in which includes being capable of inhabiting and animating vegetable matter at will, including those with alien origin,<ref>{{cite comic |date=September 1985 |title=[[DC Comics Presents]] |story=The Jungle Line |issue=#85 |writer=[[Alan Moore|Moore, Alan]] |penciller=[[Rick Veitch|Veitch, Rick]] |inker=[[Al Williamson|Williamson, Al]]}}</ref> and move towards places wherever there's life.<ref name=":1" /> Swamp Thing also possess various esoteric abilities, including able to change size and shape with control over the vegetable matter within their given body and can even travel through time.<ref name=":1" />  Swamp Thing also possess superhuman strength<ref name=":1" /> and other attributes capable of contending with powerful adversaries of great strength including the likes of [[Captain Atom]], [[Etrigan the Demon]], and [[Superman]] and also possess regenerative powers.<ref name=":1" />

=== Weaknesses ===
Swamp Thing is susceptible to chemical compounds in which typically prove disastrous to plant-life, making him capable of being poisoned. His powers can be impaired or completely disrupted if his connection to the Green is also cut off by mystical or scientific applications.

==Other versions==

* '''Lady Weeds:''' A predecessor of the Swamp Thing prior to avatars commonly adopting the "Swamp Thing" codename denoting their status. A [[Victorian era]] avatar active in the 1800s, she was known to be a particularly ruthless avatar who slayed all her rivals and managed to convince the Green to cease by first killing their latest rival who originated from Ireland before causing the [[Great Famine (Ireland)|Great Potato Famine]], a symbolic gesture of her power.
