History Main / SewerGator

Of course, this trope is entirely fictional and unrealistic. Not only because it relies on AbsurdlySpaciousSewer, itself a fictional and unrealistic trope, but also because there's just plain nothing to ''eat'' in a sewer, and alligators (and crocodilians in general) need to bask in the sun in order to properly digest their food or else it will rot in their stomachs. In addition, the sewers used for this trope are depicted as the sewers under streets and sidewalks. These sewers are used for storm run-off and drainage to prevent flooding. A baby gator flushed down a toilet wouldn't end up there, but would instead go into the water treatment system, where the filters and chemicals found in a water treatment plant would quickly kill it.

* In 2023, [[https://www.bbc.co.uk/news/av/world-us-canada-65566980 footage]] of an alligator found in a drainage pipe was released -- although this was in a storm drain, rather than a true sewer.

* ''ComicStrip/TheFarSide'': A New York sewer-gator goes back to Florida to visit his relatives, and arrives at their riverbank in a taxi, walking upright and wearing a [[HawaiianShirtedTourist Hawaiian Shirt]].

** ''Anime/PatlaborTheTVSeries'': "The Underground Mystery Tour": While investigating a series of thefts at the station, they learn about tunnels beneath the reclaimed land that look an awful lot like sewers. Inhabitants include numerous rats, feral cats, the homeless man behind the thefts, and an enormous albino aligator that chases them around for the last third of the episode.
** ''Anime/PatlaborTheNewFiles'' episode "The Dungeon Again": When they hear about a very valuable pearl that was secreted by an albino alligator that was recently captured from the sewers beneath the [=SV2=] hanger, some mechanics go into the tunnels to see if they can find some more and a rescue team is sent in after them when they do not return. Hilarity ensues when they run to {{booby trap}}s left a by a crazy guy living there [[spoiler: and when they find the "pearls", it turns out that they were actually ''eggs''.]]
* ''Anime/PokemonTheSeries'': The Orange Islands episode "The Mystery Menace!" could be seen as a reference to this trope, as it involves a reptilian Pokémon being abandoned in the sewers (though it was floated into them in a box rather than flushed), growing to gigantic proportions, and attacking the main characters. Unlike most examples, the reptile in question (a Bulbasaur) isn't actively malicious; the reason it's kidnapping people and Pokémon is so that it can have a friend. It ultimately gets its wish at the episode's end, as the local Nurse Joy offers to take care of it.

* ''{{ComicBook/Batman}}'' #577 -- "Mike and Allie": While searching for the source of the rats that are infesting the [[ElaborateUndergroundBase Batcave]], Batman finds a blind girl who ran away from home and lived with a group of sewer gators after her [[AbusiveParents abusive foster parent]] flushed her pet alligator down the toilet.

A third story kickstart the plot by having a Nile Crocodile escaping into the sewers as Cattivik is washing, and is shown to be so harmless that the protagonist briefly considers to adopt him.
* ''ComicBook/{{Daredevil}}'' #180 - "The Damned": [[IntrepidReporter Ben Urich]] realizes a bag lady in pictures of an abandoned subway tunnel looks like the missing Vanessa [[ComicBook/TheKingpin Fisk]] and contacts Daredevil to help him find her. While they are looking for Vanessa in the tunnels, Ben and Daredevil are captured by a group of homeless people.

Crocodiles are sometimes substitued for alligators, to much the same practical effect. Other variants sometimes replace crocodilians with some other variety of exotic pet reptiles -- giant mutant lizards turn up from time to time; more parodic examples may throw in giant mutant goldfish and the like. Depending on how wild a work cares to get, there may be a whole ecosystem of carelessly disposed-of animals down there.

* ''Videogame/KingdomOfLoathing'': Sewer Gators live in the Maze of Sewer Tunnels that connect the clan basement with Hobopolis. They're not descended from flushed-away baby gators -- they just wandered in through regular sewer openings and grew so big on a diet of rats that they couldn't fit back the way they came, so they're stuck down there and a little cranky about it. The actual descdants of improperly disposed-of pets -- or, well, deceased pets -- are the giant zombie goldfish that also live down there (you know how goldfish grow larger or smaller depending on how big their tank is? Well, that goes for the undead kind as well, and a sewer system's pretty large...)

Alligators that have been flushed down the toilet [[ExactlyWhatItSaysOnTheTin will end up living in the sewers down below the streets.]] Most of the time, these alligators can be an example of NeverSmileAtACrocodile. They are sometimes said to be albinos, like many real cave-dwelling creatures, due to living in a mostly lightless environment (even though cave-dwelling albino creatures are that way in real life due to having ''evolved'' to be that way over countless generations). Many fictional works make alligators grow to gigantic proportions or become indestructible killing machines from all the chemicals (often growth and/or rage inducing) found in sewers.

Of course, this trope is entirely fictional and unrealistic. Not only because it relies on AbsurdlySpaciousSewer, itself a fictional and unrealistic trope, but also because there's just plain nothing to ''eat'' in a sewer, alligators (and crocodilians in general) need to bask in the sun in order to properly digest their food or else it will rot in their stomachs. In addition, the sewers used for this trope are depicted as the sewers under streets and sidewalks. These sewers are used for storm run-off and drainage to prevent flooding. A baby gator flushed down a toilet wouldn't end up there, it would instead go into the water treatment system, where the filters and chemicals found in a water treatment plant would quickly kill it.

The alligator-in-the-sewer thing is probably one of the oldest UrbanLegends UsefulNotes/NewYorkCity has.

Since most of the frogs aren't really capable of standing up to the rats, Thor decides to investigate the frog's legends about "dragons" that live in the sewers and they turn out to be the Piper's alligators. Thor steals his instrument away and leads the gators to feast on the rats.
