History Main / AlienFairFolk

* ''ComicBook/WonderWoman1942'': Nymphs of Greek myth, and their ruler Artemis, turn out to actually be {{Lunarians}}.

* "Literature/ThoseEyes": This story is about the activities of a group of alien beings whose origins are not made explicit, but who are responsible for both fairy legends and UFO sightings, and are struggling to keep their power in a world increasingly full of people who believe in neither.

** We later learn that various [[AnimalAnthropomorphismTropes anthropomorphic animals]] from mythology like [[OurWerewolvesAreDifferent werewolves,]] [[{{Tengu}} tengu,]] the [[OurMinotaursAreDifferent Minotaur,]] the [[Literature/JourneyToTheWest Monkey King,]] etc. are members of a lost civilization of [[UpliftedAnimal Uplifted Animals]] called Furmians.

There are two variants of this trope. The first one is the so-called [[AncientAstronauts paleocontact theory]] which implies that various legendary creatures (gods, demons, angels, fairies, gnomes, etc.) are actually extraterrestrials who visited Earth many centuries ago. The other variant is the so-called "interdimensional hypothesis" proposed by ufologist John Keel and astrophysicist Jacques Vallee; according to it, the fairytale creatures (who are actually {{Ultraterrestrials}} possibly of electromagnetic origin) are nowadays posing as aliens in order to trick humans. In real life, a third view disbelieves they're real beings, but hypothesizes both are a result of our folklore (based partly on hypnogogic hallucinations), with space aliens taking the place of fairies as our ideas change.

* ''Franchise/TheWitcher'': The Aen Elle are elves from a parallel dimension. They have a terrifying reputation, some neat magic tricks (those involving teleportation and portal travel in particular) and a culture steeped in BlueAndOrangeMorality, and while they love to paint themselves as an implacable force of nature, they are physically indistinguishable from "ordinary" elves and quite mundane once you get behind the facade.

[[folder:Film]]

* ''Franchise/MarvelCinematicUniverse'': Though in [[ComicBook/TheMightyThor the comics]] their relationship to Earth is a little more complicated, in the movies, all the creatures of Myth/NorseMythology are aliens, plain and simple. Subverted in ''Film/ThorRagnarok'', where they're [[DoingInTheScientist back to identifying as gods again]], though the difference is split in that they do have history in the greater galactic community.
* ''Film/{{Vampirella}}'' has vampires coming from the planet Drakulon. Seeing as it never got any sequels, this was never retconned like in the comics.

* In the ''Literature/RiversOfLondon'' novels, it's TheFairFolk that are real, but modern-day witnesses usually report run-ins with them as alien/UFO sightings. Peter has a standing arrangement with a UFO-buff to craft the gadgetry he uses to detect fey activity; he allows the craftsman to keep right on assuming they're alien-detectors, figuring that's a more plausible cover story than AWizardDidIt.

** Demons are descended from micro-organisms that evolved on the moon during eath's Triassic period. A chunk of the moon broke off after being hit by a meteor and plummeted to earth, bringing the organisms that would eventually evolve into demons with it, and creating the island of Hybras where they have lived ever since.

* ''LightNovel/GoblinSlayer'': It's revealed that [[spoiler:the Goblins]] actually come from the Moon.

It is, however, ambiguous if any ''[[TomatoSurprise characters]]'' ever believed Gems were magical beings from Earth. Most humans are FantasticallyIndifferent to them in general, Steven called doesn't particularly react to this part of the revelation even though he'd previously been calling them "magic", and his father directly calls them "aliens" in a flashback to years earlier.

* ''[[Podcast/{{Kingmaker}} The Kingmaker Histories]]'' features a race called Good Neighbours, who are reality-warping, extremely long-lived humanoids from AnotherDimension.

* ''Podcast/{{Kingmaker}}'' features a race called Good Neighbours, who are reality-warping, extremely long-lived humanoids from AnotherDimension.

* ''TabletopGame/WarhammerFantasy'': Background material in the older editions suggests that the Orcs and Goblins were accidentally brought to the planet as spores that hitched a ride on the Old Ones' spaceships.

* ''Literature/TheLunarChronicles'' retells well-known fairy tales in a sci-fi setting. Lunars, humans who [[{{Lunarians}} live on the moon]] and have developed PsychicPowers, stand in for the various fairy or witch characters, with their powers even referred to as "{{Glamour}}s."

* ''Series/QuatermassAndThePit'' deals with ancient aliens who not only gave the human race intelligence, but who are the inspiration for supernatural beings, most notably horned demons.
