21 Fictional Worms Deserving of Horror & Devotion

Art by Maxime Desmettre

Humans lord over the Earth while worms wriggle and writhe through the soil underfoot.

Or at least that's how we choose to see it in the natural world, with only occasional concerns over scalp-based games of pinochle.

Venture into the unnatural world of fiction, however, and you'll find various worms that turn our anthropocentric attitude right on its ear. Some of the creatures ahead inspire revulsion and fear, while others demand nothing short of complete human devotion.

So let us open the Sacred Book of the Worm. Let's slide out of our human skin and enter a world of squirming horrors.

The Worm in the Cellar

Classification: Biochemically Altered Human

Description: When agreeing to spend the night in a haunted house for a $15,000 pay off, you generally accept a certain degree of Scooby-Doo-esque shenanigans. You most certainly don't expect someone to inject you with a complex enzyme molecule that gradually disintegrates your bones but leaves your nervous system and vital organs intact. In the second season of Rod Serling's "Night Gallery," a war criminal finds himself in just this predicament, forced to choose between a loaded revolver and life as a gelatinous worm-man.

"If this strikes you as absurdly far fetched I suggest you pay another visit to the basement," instructs his captor, the son of a musician tortured during the war. There, he says, one may find a fully transformed worm-man squirming about in the dark. Overcome by horror and convinced by trails of slime and an injection mark on his arm, the war criminal chooses the gun and never inspects the empty cellar.

Classification: Cryptid Death Worm

Description: Also known as the Mongolian Death Worm, the Allghoi Khorkhoi (large intestine worm) is said to reach five feet in length, spit acid and discharge electric shocks. While this monster allegedly makes its home in the sands of the Gobi Desert, lack of proof confines it to the world of cryptid fantasy for now.

The Worms of 'Squirm'
Horror on Screen

Classification: Electricity-Crazed Man-Eating Earthworms

Description: Who will be the worm face? Perhaps all of us, because as rural Georgians learned back in the late 1970s, downed power lines can raise legions of bloodthirsty earthworms up to bore into our flesh, flood our homes and munch down our loved ones.

The Carnictis Sordicus

Classification: Toothed Monster Worm

Description: With a name like "vile meat-weasel," you know this specimen is far from cuddly. Native to the abyssal chasms of Skull Island, these bloated worm creatures are among the more disgusting annelids on the list. While they first seem little more than calf-sized worms, their toothy mouth parts and propensity for swallowing humans whole is enough to thoroughly revolt this writer and make him forget everything else about their island home.

A Freak Named Worm

Classification: Mutated Human

Description: The demented Elijah C. Skuggs transformed many a mundane human into a repulsive freak, but poor worm here stands out as one of his least-human experiments. Thanks to a generous application of the mutagen Zygrot 24, Worm's body is now a boneless, segmented tube. Thankfully, he can still wear his eyeglasses and retains his powerful intellect, but his limbless condition leaves him powerless to wipe his own butt.

The Graboids

Classification: Subterranean Sandworm

Description: The great American graboid continues to capture our imaginations, as well as our ankles -- dragging us into its gaping, beaked maw with three tentacle-like appendages. Sometimes they leave the head. Fortunately, their dependence on loose desert soil and large prey drastically restricts their habitat.

The Purple Worms
Art by Michal Ivan

Classification: Monstrous Earth Worm

Description: This 80-foot-long wormstrosity likes nothing more than to burst out of the ground and swallow treasure-seeking adventurers whole. That's what can happen if your tangle with the toothy mouth end, while the creature's posterior boasts a deadly stinger capable of skewering several halflings in one go.

The Mirocaw Harlequins

Classification: Degenerate Humanoid Species

Description: It is right and good to fear the clown, gentle reader, especially when all that pale grease paint masks a degenerate race of humanoid worms. The town of Mirocaw is rife with these creatures, which saunter through the streets during their yearly Feast of Harlequin and burrow beneath the surrounding hills to engage in unspeakable rites.

The Vendren Worm
Art by Jamie Oberschlake

Classification: Pluralizing Monster Worm

Description: Beware the worm that walks among us, such as the dreaded Venderen Worm that haunts the streets of Crotalorn. Surrounded by undulating tendrils that probe immodestly at its prey, the great worm can easily gobble up a human whole. That's fine enough strength for the shadows, but such a monster needs stealth to survive in the world of men. As such, the Venderen Worm shapes its form into that of a human, in time budding additional, subservient forms as well. Very old members of this secretive species may ultimitly populate whole households with their ring of supernumerary.

The Sandworms of Titan
Art by Phill Gonzales

Classification: Extraterrestrial Sandworm

Description: The sandworms of Saturn's moon titan remain something a mystery. A curious outer mouth protects the creature's true head as it swims through an abrasive sea of sands, only peeling back when the beast emerges to feast on prey. Strangely enough, its diet depends at least in part on interlopers from various afterlife dimensions.

The Shai-Hulud
Art by draxmusthurt

Classification: Extraterrestrial Sandworm

Description: The sandworm of Arrakis stands out as one of the most astounding and influential lifeforms in the universe. These massive, water-intolerant creatures reportedly reach lengths of up to 450 meters (1,476 feet), though some report even greater sizes. They thrive beneath the sands of barren Arrakis and rise to the surface when summoned by threatening sounds or a rival worm. While the creatures boats nothing more than animal intelligence, their larval sandtrout form produces a substance with profound influence on human civilization: an awareness spectrum narcotic called Spice Melange.

Classification: Great Old One

Description: There are creatures in this universe so ancient and powerful that they attain some level of godhood in the eyes of mortal humans. And yes, some of them are worms -- such as the White Worm said to reside in a pit beneath a Derbyshire estate. Granted, it doesn't do much down there. It eats whatever humans feed it and otherwise just accepts their kinky devotion and keeps on living.

The Conqueror Worm
Art by Mike Mignola

Classification: Space Worm Demigod

Description: Space worms that try to eat your spaceship are bad. Space worms that try to decimate your entire planet and free a host of dark monster gods from their cosmic prison are far worse. Behold the Conqueror Worm, one of the 369 Ogdru Hem, the children of the Ogdru Jahad, the so-called "dragon of revelation" destined to destroy the world. The worm entity hitched a ride to earth on a returning Nazi space capsule and attempted to cleanse the planet for its dark fathers. Lucky for us, someone stopped it.

Oh yeah, and they want to wipe out humanity. Great. While highly resistant to heat and pressure in the inner Earth, the Cthonians can't handle water. Rumor has it they serve an even greater and older member of their kind known only as Shudde M'ell.

Art by Devon Cady-Lee

Classification: God Emperor of Humanity
