The Great Serpent

I think Samuel L. Jackson's gonna have a coronary.

"Oooo, yeah!" Pinkie Pie chimed in, bouncing between the two ponies. "There could be basilisks and bunyips and balrogs and even world snakes!"
"What's a world snake?" Apple Bloom asked.
The pink earth pony gave her an enormous smile. "It's a snake as big as the world, silly!"

—It's A Dangerous Business, Going Out Your Door, Chapter 3

These snakes are not just big; they're absolutely enormous.

Swallowing a human whole is easy for them. In fact, it may not even be enough to satiate them. They may be able to swallow buildings. Or celestial bodies. Or the world. They could have fangs longer than trees and venom that can kill the gods. Or they could just be ordinary snakes that are a little overgrown. Or a lot.

This is a very common motif in mythology, as there are multiple mythical snakes around the world that reach incredible sizes. Giant snakes can also be used in other settings and genres, such as Horror or Science Fiction.

In order to qualify for this trope, the snake in question must be at least bigger than the Reticulated Python, the world's current largest snake species, that can grow up to 7.62 meters in length (that's 25 feet), and be big enough to swallow a person whole.

Sub-Trope to Dire Beast. Not to be confused with Basilisk and Cockatrice and Chinese Dragons, but may overlap with Sea Serpents. See also Snakes Are Sinister. Often the result of Scaled Up. For other unreasonably large animals, compare Mega Neko, Giant Spider, Giant Crab and Big Creepy-Crawlies.

Films — Live-Action

• Anaconda: While the snake from the first movie is a downplayed example — being a fully-grown anaconda native to the Amazon big enough to pose a threat to humans — the snakes present in Anacondas: The Hunt for the Blood Orchid and onward are more straight forward examples, the second movie having snakes that have been made massive from exposure to the blood orchid and through scientific experimentation with black orchids in the third and fourth movie.
• Atragon: While absent in the final product, original drafts depicts the film's main kaiju, Manda, to be a gigantic serpentine creature, with the production team calling it "Mammoth Snake".

It tries to attack Conan and ends up killed by him and Subotai (Conan impales its jaws with his sword, then Subotai shoots arrows in its head, then the heroes behead it for good measure).
• The Jungle Book (2016): In this film, Kaa the Python is depicted as being so massive that her body is draped all over the tree, and she could easily fit Mowgli in her mouth, which is fitting, seeing as she tries to eat him before Baloo intervenes.

• D-War: The Imoogi are a mythical race of gigantic snakes in Korean Mythology that surface every 500 years, the most virtuous of them all evolving into dragons. The main antagonist, Buraki, is a two-hundred foot long cobra who seeks to usurp the good Imoogi's ascension for himself.
• Gods of Egypt: Two fire-breathing giant cobras appear during one desert chase scene, pursuing Bek and Horus.

After traveling the countryside and feeding on woodland animals for a few years, it's grown enormously and appears to be somewhat larger than a reticulated python.
• King Of Snake is a Taiwanese kaiju film where the featured monster, like what the title implies, is a giant serpent.

• Mowgli: Kaa, already an overly large snake in most portrayals, is reimagined in this movie as a colossal python.
• Snake (2018) is pretty much Exactly What It Says on the Tin, and also an unofficial Foreign Remake of Anaconda. The plot revolves around an expedition to an uncharted island to recover a miracle "fruit of life" capable of curing all diseases, but the fruit is guarded by the island's giant serpents, which the crew didn't find out until late into the film. This film actually spawns a trilogy, with the third movie having a serpent large enough to battle a dozen T. Rexpy-dinosaurs all at once.
• The Snake Prince ends with the titular Prince revealing his true form in the final scene after being exposed to Sulphur smoke — as a giant serpentine beast.

• The Sorcerer and the White Snake, an adaptation of the Chinese fable Legend of the White Snake, probably contains the largest depiction of the titular character.

Myths & Religion

• Aboriginal Australian Myths: The Rainbow Serpent is an umbrella term for several snake divinities in these myths, most of which traditionally having little to do with each other. Some like Wungurr (from the "Wandjina-Wungurr" cultural complex in Kimberley) are essentially abstract Life-Force, while the Gamilaraay Garriya is simply a water monster. Examples of more concrete deities include Wonambi from the Wiradjuri and Wagyl from the Noongar, which are closer to what people typically envision the rainbow serpent to be (a Fertility God associated with water with intersex features responsible for shaping the landscape).

• Classical Mythology: As a general rule, Greek dragons were depicted in art as enormous snake with little additional embellishmet — traits such as legs, wings, and pseudo-mammalian heads mostly originate from Medieval art.
• Egyptian Mythology: Apep (or Apophis as the Greeks called him) is a giant, malevolent snake that is said to be the physical embodiment of darkness and chaos, whom the sun god Ra would do battle with during his journeys across the underworld every night. Depending on the story, it was said he lurked beneath the horizon, forbidden to enter the mortal kingdoms, and somewhere in a western mountain called Bakhu, where he lay in wait for Ra before the dawn, or after the sun set. Because of the many possibilities of his location, he eventually earned the epithet World-Encircler, and as a perpetual resident of the underworld (since Ra trapped him there), his roars would shake the underworld, while his movements caused earthquakes. There are also several other gigantic divine snakes that are actually heroic and assist Ra and the other gods at battling Apep.
• Hindu Mythology has several, but perhaps the most famous is Ananta Shesha, a giant, multi-headed cobra who serves as the couch of Vishnu the Preserver. He is said to have anywhere from five to five million heads, each one constantly sings the glories of Vishnu from each of his mouths, while the entirity of all creation is carried on his hoods.

• Japanese Mythology:
  • Uwabami (lit. Gluttonous Eater in older times, currently python) were humongous snakes who were said to be able to devour horses whole in one gulp, as well as adore sakè. Jashin (serpent gods) were also pretty common, with the most famous one being the Kami of Mount Ibuki who was killed/killed Takeru Yamato, though only in certain versions of the myth (in others, the Kami is a massive white boar instead).
  • Subverted by Yamata no Orochi, who's often depicted as a colossal snake but is described as a dragon in the Kojiki and in other works.
• The Grootslang from South African folklore is described as a snake forty to fifty feet in length, sometimes with diamonds for eyes, that guards a fabulous treasure either in a cavern near the Orange River or in the pool of the King George Cataract at Aughrabies Falls. The legend is believed to have originated from exaggerated reports of local pythons, which can exceed twenty feet in length.

Tabletop Games

• In Nomine: At its height, Jormungandr was so huge that it could coil around the entirety of the world. Currently, following centuries of recovery after being decapitated, it's only regrown to the point where its head is sixty yards long and it stands two stories tall when rearing up.

Theme Parks

• Lost Island Theme Park has Matugani, the giant Emerald Serpent of Wisdom that serves as the basis of one of the park's roller coasters.

• Boktai 2: The Final Boss is the Eternal Piece Jormungandr, which threatens to destroy the world if unsealed. The arena takes place atop its coiled body, which seems to go on for eternity.
• Bot Gaiden: One of the bosses of the game is a gigantic robotic cobra called... Cobrabot.

• Jurassic World Alive: The Apex and Unique Raid bosses Hydra Boa and Troodoboa are large enough that even when coiled they stretch the entire width of the Jurassic World main thoroughfare and still look the giant sauropods like Brachiosaurus in the eye. Their playable versions while significantly smaller, are still the largest non-dinosaur creatures in the game, alongside the other snake hybrids Spinoconstrictor and Dilophoboa. Fittingly, this is due to them all sharing the same rig and animations made for the massive Titanoboa and Titanoboa Gen 2, the latter of which is needed to hybridize and level up Troodoboa, and the former needed to hybridize and level up both Dilophoboa and Spinoconstrictor.
• Jurassic World: The Game:
  • Titanoboa, Dilophoboa, and Gigantophis easily rank among the game's largest Cenozoic creatures, as they are big enough to occupy at a significant portion of their entire enclosures, which are big enough to house the elephant-sized sloths Megatherium and Eremotherium, among other mammalian giants. Their feeding animations also come off as a little overkill, since the dodos used to feed all Cenozoic predators are small enough that the snakes can swallow them whole without effort or risk of injury.
  • The snake boss Ouroboros could easily be considered a contender for the largest creature in the game, as it's arena is little more than a small canyon and it's still big enough to take up most of the space inside it.
• Krut: The Mythic Wings, a game based on Thai myths, have two different naga (giant serpentine monsters with draconic features from Thai folklore) as bosses.

• The Last Faith have an area in the castle filled with gigantic serpents, each of them large enough to swallow your protagonist with a single gulp. You need to fight their heads, one at a time, to proceed.
• The Legend of Dragoon: the third major boss is Uroborus, a giant, seemingly eyeless snake who guards the exit of a seaside cavern the heroes have to cross to reach Basil. He can attack by either gnawing at the characters, spitting liquid poison or toxic gas and, as a gimmick, can position himself so that Lavitz and Dart's melee attacks cannot reach him, forcing them to rely on either Shana's arrows or spells.
• The Legend of Zelda: Twilight Princess features Lanayru, one of the Spirits of Light whom took on the form of a serpent. Unlike most of the other examples, Lanayru is a benign spirit that warns Link of the dark power.
• Legends of Runeterra: The Celestial aptly titled "the Serpent" is a massive cobra made of stardust. Ironically it's actually one of the weakest celestial units stat-wise, but costs 0-mana and has the Challenger keyword which lets it handpick an early-game enemy to deal damage to in combat.
• Metal Slug Code J: The guardian / boss of the pyramid's inner sanctum, Apep the great serpent, is a giant water-dwelling cobra who attacks players on floating islets from underneath. The player characters needs to jump from one platform to another to avoid getting devoured, while firing back at Apep. Once Apep's health is down to its last bar though it simply swims away rather than fighting players to the death.

  • In the first game, a monster known as the Crypt Hydra, a mummified two-headed snake, was meant to be the final boss but was ultimately cut out.

• Ninja Emaki have an obscure giant snake Yōkai, a gigantic albino Uwabami, serving as a boss.
• Persona: Black Viper is a recurring spell in the series that's unique to certain high-level Personas.

• Pokémon: Onix is a massive rock-type Pokemon in the form of a giant snake. It is the tallest rock-type in the world.
• Resident Evil features the Yawn, a snake grown to giant size by the T-Virus. It has the ability to inflict "poison" status on Jill or Chris. If that's not bad enough, it's encountered twice.

• Shin Megami Tensei IV: Apocalypse: Sheesha of the Divine Powers is an absolutely enormous fiery snake that can grow big enough to curl around the sun. In the game, it's the only enemy that's depicted with a 3D model. Its sheer size and power drives a major part of the plot, as the multiple factions in opposition to the Divine Powers are forced to team up to take it down.
• Slither.io: Snakes grow longer as they eat neon dots scattered around the arena or dropped from other snakes after they are killed. It's possible to grow so much that the snake reaches tens of thousands of units in length (the growth stops eventually, so it's not possible to grow long enough to circle the whole map), with them also being thicker than smaller ones.
• Songs for a Hero have it's first boss, the Queen Cobra, a gigantic snake monster whose head is larger than your body.
• Sonic Forces: While Sonic is exploring the Luminous Forest, Amy picks up an unidentified life form in her radar, which turns out to be a giant snake that erupts from the ground. Enraged by the noise of the battle between the heroes and Eggman's robots, it attacks Sonic and manages to swallow him, though the hedgehog forces it to regurgitate him by attacking its guts. An illusory, much larger version of the same snake is later used as the arena during the first boss battle against Infinite.

Real Life

• The Paleogene period hosted a wide variety of giant snakes.
  • The largest snake species to ever exist was the Titanoboa (Titanoboa cerrejonensis), a snake that existed in the Paleocene Epoch (around 60 million years ago) that grew to be at least 13 meters in length and weighed more than a ton. Given its massive bulk, it spent its life in the Amazonian swamps of modern-day Colombia. If such animals still lived today, these snakes could have strangled full-grown horses, being ancestors of the modern boa constrictor. While it was initially thought to be an apex predator that fed on large mammals, more recent discoveries of fossils of its head and jaws have led scientists to believe that it was instead a specialist fish-hunter.
  • Second only to Titanoboa, Gigantophis was a large prehistoric snake that lived in North Africa 40 million years ago, estimated to be over 10 meters long; though a recent study adjusted this length estimate to 6.9 meters, much closer in size to the largest extant snakes.
  • Palaeophiids were a group of large sea snakes, members of whom could grow up to 5 to 12 metres.
• Measuring living snakes isn't an easy task, but as far as anyone knows, the largest extant snakes are the Reticulated Python (Malayopython reticulatus), which can reach 25 feet, and the Green Anaconda (Eunectes murinus), whose maximum length is unknown but several skins exist which came from individuals at least 24 feet long.^note Stories exist of anacondas up to 40 feet long, but there is no hard evidence for these, just written accounts that may be exaggerated or even entirely made up. The Green Anaconda is definitely the heaviest snake at 200-400 pounds. The longest extant venomous snake is the King Cobra (Ophiophagus hannah), with a record length of 18 feet and an average of over 10. Besides its extreme length and potent venom, the King Cobra is also a highly alert snake with the capacity to raise almost half of its body length off the ground, meaning it's a Great Serpent that can look the average human in the eye. Naturally, it was an inspiration for myths and religious practices in the places where it's native. The Basilisk is probably based on cobra sightings.
