Swamp Monster

Go To

As we all know, Swamps Are Evil, and filled to the brim with dangerous animals, plants, and tribes. But sometimes, they are also home to something a little more nasty.

The Swamp Monster is a monstrous creature found almost exclusively in the swamp. It is where they have made their home and they will not or perhaps cannot ever leave. On the rare instances they do, they will likely return to their home eventually.

Expect them to be hostile towards any visitors unfortunate enough to stumble upon their territory, though on occasion benevolent swamp monsters do exist. They usually have the ability to stay submerged in the water, if the water isn't where they usually reside.

The exact nature of a Swamp Monster varies between different works, but common forms it takes include:

See also: Sea Monster, Stock Ness Monster for similar creatures with a different choice of habitat.

  • In Toriko, while exploring the First Biotope, Sunny and Komatsu run into an ancient giant swamp which is the hunting ground of several massive creatures: just upon arriving, they see a giant fresh-water moray eel, a massive multiple-headed snail and finally a crocodile-mouthed shark who devour both creatures in one gulp.

    Comic Books 
  • Big Bang Comics: Bog is a demon who Escaped from Hell, and nearly killed the Devil in the process. He now dwells in a swamp on Earth and fights any attempt by the forces of Hell to drag him back.
  • DC Universe:
    • Solomon Grundy is a supervillain whose origins are of a deceased criminal, Cyrus Gold, whose body was dumped into Slaughter Swamp, where the mutagenic chemicals and mystical energy revived him as a gigantic zombie at least partly composed of plant matter. He was introduced as an enemy of the Golden Age Green Lantern, who had difficulty fighting him due to his ring's weakness to wood, which was what Grundy's swampy body was largely made from. Grundy has gone on to menace many other heroes from throughout the DC universe.
    • Swamp Thing is one of the Trope Codifiers for the Muck Monster variety and appears to have eclipsed Man-Thing in fame due to his appearances in numerous adaptations. Swamp Thing, unlike many other examples of this trope, is a full-fledged, if unusual, superhero. There have been many different holders of the Swamp Thing name over the years, with perhaps the most famous version being Alec Holland. Swamp Thing is a being whose body is composed of vegetation and plant matter, and who has developed very powerful Green Thumb powers that actually make him an elemental avatar of nature.
  • Eerie Magazine's fifth issue featured a cover story called "The Swamp God Strikes", about two explorers and their guide, tracking the titular monster, which turns out to be a surviving T. rex. And they are lunch.
  • The Heap is the Trope Maker for comics swamp monsters, specifically the Muck Monster variant. There have been multiple versions of the character, but the most famous example is the Baron Eric von Emmelman version, a WWI pilot who crashed into a swamp, where his will to live caused his body to merge with the swamp itself.
  • Marvel Universe
    • The Incredible Hulk: Joseph Timms was a petty criminal who escaped from prison to be with his dying wife. He ran into the Florida everglades, only to drown in the marshes. Decades later, after the Hulk accidentally spilled radioactive waste into the swamp, Joe Timms was resurrected as a swamp creature now called the Glob. The Glob's body is made out of muck and dirt, with the Hulk's punches simply sinking into it, making him a difficult opponent for Hulk to defeat.
    • Manphibian is an Expy of the Gillman and part of the Marvel's monsters lineup. Despite his resemblance to his inspiration, his origins are extraterrestrial in nature. He ends up becoming a member of the Legion of Monsters.
    • Man-Thing is one of the Trope Codifiers, being among the most famous Muck Monster swamp monsters in all of fiction, rivaled only by his DC counterpart Swamp Thing. Man-Thing was one a scientist named Dr. Theodore Sallis who attempted to recreate the Super Serum used on Captain America, before an accident led to the serum fusing him with the mystical energies of the swamp, transforming his body into a humanoid mass of swamp material. As Man-Thing, it has lost his human intelligence and is mostly a creature of instinct, though it is sensitive to emotions, particularly fear, which will cause it to burn targets who exhibit said emotion. Despite its limited intelligence, Man-Thing often ends as an incidental hero. Later it's also revealed the mystical energies made Man-Thing the guardian of a Nexus of Realities present in the swamp.
  • The pre-Code horror comic This Magazine is Haunted ran a story called "The Slithering Horror of Skontong Swamp", where a prison escapee runs afoul of some waterlogged undead creatures.

    Fan Works 
  • Equestria Divided: Ponies who die in the swamps of Froggy Bottom Bog sometimes return to life as swamp shamblers, lumbering masses of mud, moss and tree branches in vaguely quadrupedal shapes. They also emanate clouds of toxic gases, and House Everfree sometimes uses them in battle to sicken and poison enemy troops.

Too bad it turns out the monster has LOTS of siblings of its own out there.

    Tabletop Games 
  • Dungeons & Dragons:
    • Bog hounds are canine monsters that arise from a cursed moor - the majority look like wolves comprised of the mud and straw of their home marsh, while the moor hound that leads them is formed from the vapors of the bog, and thus can only be hurt with magic weapons. They don't fare well in sunlight, which causes bog hounds to instantly freeze into easily-broken statues of hardened mud and plant matter, and makes the moor hound vulnerable to even ordinary weapons. But until that moor hound is slain in the daylight, it and its pack will continue regenerating each night to haunt their moor.
    • A swamp that's tainted by magical pollution can create mudmen, humanoids made out of swamp mud. Not very intelligent, they instinctively try to drown anything that enters their territory, often destroying themselves in kamikaze attacks as they try to smother their foes.

    • Some editions of D & D, as well as Pathfinder, offer variant rules on the mummy to create swamp-dwelling undead more along the lines of the bog bodies of European peat bogs, for dungeonmasters who find the usual Ancient Egypt Fantasy Counterpart Culture setting a bit too predictable and played-out.

    • DragonFable: The ironically named "Crystal Clear Lake" is a murky swamp with mobs there including a Man-Thing-esque monster called the Swamp Shambler, as well as a Gill Man-type creature called the Lagoon Goon. The latter is also capable of summoning a monstrous fish to attack the player.

  • Memoria Freese: One story event features a creature known as the Swamp King, who is a giant slimy Muck Monster mass of eyeballs and tentacles.

These things are tough enough to take on and defeat trolls.
  • The Witcher has enough of these to have a whole book about them, which include: Drowners and Drowned Dead, which are essentially dead men revived by the swamp as zombie/ghoul like creatures. There's also the Bloedzuiger, a gigantic monster with a leech-like head.
