History Main / FantasyAliens

** ''Literature/TheColourOfMagic'': Near the end of the book the protagonists encounter a water troll who informs them that its an alien who reached the Disc World by literally falling off another planet and landing there.

* ''Manga/{{Naruto}}'': The founder of modern ninjitsu is later revealed to be a HalfHumanHybrid born between a human and Kaguya, a woman from the Otsutsuki clan of "celestial beings" that hail from another world with many others like themselves. These beings tend to send one of their own to underdeveloped planets and try to find a God Tree, which absorbs the blood and life of the native beings of that world to produce "chakra". The tree itself is an extraterrestrial plant that crashed on Earth via meteorite several millennia ago, and was reversed by ancient humans as a divine entity. Some Otsutsuki harvest the fruit until it kills all of the native inhabitants, while Kaguya ate the fruit of the tree, settled on the Earth and came to be revered as a goddess.

* ''Literature/CodexAlera'': in a book series about Romans with ElementalPowers, the Vord are a HordeOfAlienLocusts strongly hinted to be (yes) aliens from space, though they’ve lain dormant for centuries. They’re first encountered inhabiting an enormous crater with a huge metallic pillar jutting out from its exact center, inside which their HiveQueen hibernates. In a later book, after the Vord awaken, the Vord Queen declares that her species is conquering other worlds out among the stars, and that even if she’s destroyed, the Vord will inevitably return one day.

* ''Videogame/{{Darkstalkers}}'': The game features mostly MonsterMash of well-known fantasy monsters... And then you have Huitzil and Pyron, the former being an automaton of extraterrestrial origin and the latter being an EnergyBeing alien.

* ''VideoGame/KingdomRush Frontiers'': one of the heroes is an alien warrior in an openly fantasy series, fighting with energy blades, drones and even summoning his spaceship to kidnap enemies. The jungle levels also feature {{Xenomorph Xerox}}es which apparently spawned from a starship.
* ''Videogame/TalesOfLegendia'': Humans, referred to "Orerines", are under constant threat and harassment by another group of invaders called the "Ferines", an aquatic-based of unknown origins that look identical to humans, and have developed a powerful superweapon that could destroy all land and wipe out human civilization as we know it. However, a very late plot twist reveals that [[spoiler:it's the ''Orerines'' (humanity) that are the invaders. Thousands of years ago, the world the story takes place in was an ocean world with no landmasses. The continent that the story takes place on is actually a gigantic ColonyShip that is able to become and create inhabitable land. The Ferines were the original inhabitants of the planet, whose lives began disrupted and oppressed when the human ship terraformed their world.]]

** The franchise sometimes leans towards sci-fi, but even in the more strictly fantasy settings aliens can be a somewhat common occurrence. Notable examples are Xemnas and the Lunarians in ''VideoGame/FinalFantasyIV'' (as well as the Creator from the sequel, ''VideoGame/FinalFantasyIVTheAfterYears'', Jenova in ''Videogame/FinalFantasyVII'' and Garland and the Terrans in ''VideoGame/FinalFantasyIX'' are all aliens that serve as big bads of the story.

* ''VideoGame/ChronoTrigger'' is a story involving time travel with a heavy slant towards the fantasy side of the spectrum. The main antagonist, Lavos, is a parasitic being who arrived on Earth in the time of the dinosaurs and has been interfering with the course of the world ever since.

* ''Videogame/GrandiaII'': Although the God of Light, Granas, and God of Darkness, Valmar, are revered as magical gods, the story slowly starts to reveal that this is a grave misconception. The first clue comes when the party finds the "Granasaber", a magical sword that was said to be so powerful that it created a giant gorge on the world's surface -- and it turns out to be a massive spaceship in the shape of a sword. Later, the team also meets an "angel" that was one of the footsoldiers that Granas used in the war against Valmar, and she turns out to be an android. Even later still, when the party finally sees the final moments of the war between Granas and Valmar, it turns out to have been a massive space battle between Granas and his/its/their robotic soldiers and Valmar, which is much more like an eldritch abomination.

[[AC:Film -- Live-Action]]

[[AC:Literature]]
* ''Literature/{{Grunts}}'': The second half has an AlienInvasion by a race of scorpion-like aliens with OrganicTechnology, which they use to replicate the titular Grunts' guns (the Grunts being an orcish warband who stumbled upon a dead dragon's hoard of modern weaponry). Their ship touches down in the obligatory desert region. When they finally make diplomatic contact, they reveal that [[BloodKnight they just like fighting a lot]].
* ''Literature/TaleOfTheComet'' involves an [[AIIsACrapshoot evil, alien A.I.]] called the Overseer invading a StandardFantasySetting by way of a half-[[YouWillBeAssimilated assimilated]] battlecruiser crash-landing on it. The battlecruiser's owners, the humanoid Rael, train the native population to fight it off.
* ''Literature/FaerieWars'' combines alien and fairy myths in a generally fantasy setting. The protagonist discovers a portal to {{Fairyland}}, which is a StandardFantasySetting occupied by several races (all called Faeries) who are at war with each other, including an evil race referred to as demons. The demons turn out to be responsible for all reported alien sightings, as they kidnap people and keep them on what resembles [=UFOs=], but they can also be summoned by a SummoningRitual, and hail from AnotherDimension rather than space.

[[AC:Tabletop Games]]

** ''Expedition to the Barrier Peaks'' is an adventure module in the ''TabletopGame/{{Greyhawk}}'' setting, where a group of adventurers from the otherwise firmly fantasy world explore a cavern that turns out to be the long-buried remnants of a crashed starship. Within it, the characters will find themselves battling malfunctioning robots and alien creatures and may be able to scavenge advanced energy weapons and PoweredArmor.

[[AC:Video Games]]

** Sometimes leans towards scifi, but even in the more strictly fantasy settings aliens can be a somewhat common occurance. Most notably Xemnas and the Lunarians in ''VideoGame/FinalFantasyIV'' (as well as the Creator from the sequel, ''VideoGame/FinalFantasyIVTheAfterYears'', Jenova in ''Videogame/FinalFantasyVII'' and Garland and the Terrans in ''VideoGame/FinalFantasyIX'' are all aliens that serve as big bads of the story.
** Final Fantasy also has a recurring alien race known as Pupu who appears in multiple games, usually in a cameo capacity with their true motives and intentions being unknown.

* In ''VideoGame/TheLegendOfZeldaMajorasMask'' a group of monsters resembling the Flatwood Aliens attack a ranch that need to be stopped. Their "ship" for want of a better term, appears as a glowing ball of light. Majora's Mask is otherwise a completely straight fantasy setting.

* This was one of the reasons the ''Burning Crusade'' expansion of ''VideoGame/WorldOfWarcraft'' received backlash from lore fans when it was first released. While the orcs were from another world in the first ''Warcraft'' game, it was handled in a solidly fantasy manner, involving stock fantasy races, and the worlds were connected using a magic portal.

** However, over time, ''World of Warcraft'' would so thoroughly embrace the idea of being a FantasyKitchenSink that "aliens" feel as at home as anything else. By the time the ''Legion'' expansion had the Burning Legion literally invading with spaceships from their homeworld (instead of just portals to the Twisting Nether), and us counter-invading with a ship capable of OrbitalBombardment, no one really batted an eye (and newer players were surprised to learn the game was ever limited to a setting that only just barely averted FantasyGunControl).

* While ''VideoGame/FinalFantasyVII'' does have a megalopolis and light space travel, Jenova still solidly fits into this category, being a shape shifting alien that landed on the planet in ancient times and would have overrun it had the precursor species not imprisoned her. Rather than fight with traditional alien weapons, her very biology is the threat to life on the planet with cells that can infect individuals and bend them to her will.
