Transhuman Aliens

"We WAH like you ONCE but now we ah di-FER-ent... SAH-tain WEAK-nesses have been RE-moved."

- A Sai-BAH-man, Doctor Who, "The Tenth Planet"

Related to the Planet of the Apes Ending, and sort of like Was Once a Man for an entire species, this is where a group of alien/future creatures (typically those encountered by normal humans) are revealed to be the future evolutionary path of humanity. These creatures are often monstrous in appearance and behavior and this idea generally has a strong element of Humans Are the Real Monsters. Compare with Not Even Human; in this case, they are worse because they are. Note, that there are occasional instances of uplifted humans who having experienced The Singularity are benevolent and god-like.

Compare/contrast with Human All Along and Human Subspecies. Not to be confused with Ultraterrestrials. See also No Transhumanism Allowed and Transhuman.

Anime and Manga

 * The Abh from Crest of the Stars and sequels. Engineered to be space explorers they have a third eye and some modifications to the brain so they can navigate better in three dimensions. They also possess longer lifespans and adaptions to cope with extended periods of microgravity with periods of high acceleration since they were created before the in-universe discovery of Faster-Than-Light Travel and Artificial Gravity.
 * Possibly true at the end of Ergo Proxy:

Comic Books

 * The Sheeda from Grant Morrison's Seven Soldiers series were a future posthuman species that robbed the past to support their resource-poor civilization.
 * The many races of Marvel Comics' Microverse are all descended from a future humanity which fled through time, space and dimensions to escape a genocidal war.
 * Neil Gaiman's The Books of Magic features a vision of a dying Earth where the surviving humans have evolved into tall, translucent-skinned hunter-gatherers with drastically reduced intelligence. Their bodies produce chlorophyll to help cope with the lack of nutrients left on the planet.

Film

 * The robotic alien creatures at the end of A.I.: Artificial Intelligence are a rare positive example of this. Being robots with biological components in a world where humans are extinct, the implication is either they are robots who won the Robot War with evil humans or else uplifted humans who learned the error of their ways. In either case, they are a Sufficiently Advanced Alien.
 * A borderline example in The Descent with the cave creatures who evolved from homo sapiens or an earlier ancestor.
 * Pandorum, the creatures are at first assumed to be aliens that somehow got aboard the ship. It's revealed

Literature

 * The Time Machine is an early example with the Morlocks and Eloi as future humans and neither presenting that pleasant an outcome for the species.
 * Man After Man is all about this in a heavily Humans Are the Real Monsters way. Much of the book is about various genetically-engineered species of humans all heavily dehumanized (and cripplingly overspecialized to boot). The book ends with an alien species coming to earth and destroying all life on land. They are the evolved remnants of the humans who went into space at the beginning of the book.
 * Isaac Asimov's Solarians eventually genetically re-engineered themselves into a race of hermaphrodites with psychic powers in the name of their world's social code, opposing any physical contact between human beings.
 * The Belisarius Series by David Drake and Eric Flint features in its backstory two opposing factions in a far-future war. One faction is made up of transhuman aliens, humans evolved or genetically engineered to live on alien worlds, some even evolving into gigantic Space Whales. Others scuttle about on crab-like legs that are modified ribs. The opposing faction fancies themselves the original, pure-blood humans, and wants to wipe out all the evolved and engineered subspecies of humanity. Of course, this far in the future, they aren't recognizably human any more, either.
 * More precisely, the Great Ones are so different as to be made of non-organic crystals and force fields, but think like human beings; whereas the New Gods resemble impossibly perfect humans, but have lost all compassion for those not like themselves to the point where they seem less human than the Great Ones. The core of their conflict is whether humanity should be defined by your mind or by your biology. This is why one faction is trying to alter the past into a meritocratic society, and the other into a caste-based eugenic society.
 * The Miles Vorkosigan series has three examples in the Cetagandans, the "Quaddies", and the Betan Hermaphrodites. The Cetagandans are an Evilutionary Biologist race who are continually experimenting with genetics so as to "perfect" themselves. They still look human now but it's hard to say what the future holds for them. The Quaddies are a people specifically-engineered for zero gravity with a second set of arms instead of legs. Normal humans shunned them so they fled and set up their own society after the invention of artificial gravity precluded any real need for their services. The Betan hermaphrodites are described as "Betan egalitarianism gone mad" and are relatively normal except for the obvious. They're also a minority even on their home planet though they're much in demand as sex therapists.
 * A group of Sauron Super Soldiers of the CoDominium universe invade Haven. The natives blame everything from Space Pirates to supernatural monsters. Having the Saurons rule most of the planet for several centuries does nothing to clear up the matter for most people.
 * Several Star Trek Expanded Universe novels have the crew meeting "aliens" who turn out to be heavily modified humans.
 * The Homo Ludens in the Strugatsky Brothers' The Time Wanderers are essentially.
 * In Fall of Hyperion,
 * In The Avatar,
 * Lots and lots in Alastair Reynolds' works, notably Revelation Space. The Ultras vary from human-seeming to animated works of art; the Skyjacks are permanently adapted for life in space; the Stoners are heavily augmented humans who go so far as swapping sexes and appearances the way most people choose hairstyles - Zebra, in Chasm City, has horselike legs, zebra stripe skin pigmentation, a mohawk that runs all the way down her spine, horselike eyes, and hasn't always been female. Not that any of that gives the hero a moment's pause before bedding her. In Zima Blue, outside of the Revelation Space universe, an artist who appears to be a transhuman turns out to be
 * Even more so in House of Suns, where we have a galaxy of staggeringly diverse beings, from sea-life to giant space-dwellers to semi-sentient weather, all of which are in fact evolved or modified human stock. The only reason the central characters are remotely recognizable as human comes of their spending the eons since the original diaspora flitting around at relativistic speeds and thus have passed much less subjective time in the meanwhile.
 * In Jack Vance's 1962 story "The Dragon Masters", a human colony is plagued by alien kidnappers. After fighting back and taking captives, the story shifts ahead many years, and the captive aliens have been bred into Dragons of many breeds with many purposes. When the alien slavers return, its revealed that they have done the same with their human captives.

Live-Action TV

 * Lots of examples in Doctor Who
 * The Cybermen from the page quote are not technically humans, but a nearly-identical humanoid race from Earth's long-lost twin planet Mondas, though there was an alternate universe where the Cybermen were indeed humans. Regardless they often forceably convert regular humans into more Cybermen, and presumably other humanoid species, so at least some members of the Cyber-Race fit this trope perfectly.
 * In the episodes with John Simm's Master, his minions, the "Toclaphane" are refugees from a decayed far future. They are a race of cheerful psychopaths which normally look like flying silver basketballs. Inside these "balls" are human heads, revealing their true species.
 * Doctor Who also had Daleks that were partially built from human DNA in "The Parting of the Ways" as well as a human being converted into a human-Dalek hybrid in "Daleks in Manhattan/Evolution of The Daleks".
 * Nietzscheans and the Castalian fish-people from Andromeda. Nietzscheans are humans genetically engineered to be superior Ubermenschen by a literal Nietzsche Wannabe Mad Scientist a thousand years or so before the events of the series. They can eat almost anything organic, have nanobot-enhanced immune systems, and bone spikes growing out of their forearms (in addition to the usual Super Strength and other enhanced physical abilities). The Castalians are humans genetically engineered with gills to live underwater and breathe water rather than air. They've got nifty water-tank backpacks with tubes to their neck gills for when they have to come out of the water to meet others. Nietzscheans are pretty much neutral, Castalians generally fairly good guys, although they've done some nasty things to survive in the Crapsack World after the fall of the the Commonwealth.
 * There are a few less obvious examples. For example, Dylan's enhanced strength ans a few other traits are due to his mother being a high gravity worlder. Becca has a number of enhancements such as enhanced reaction time that make her a better spacer (and were reverse-engineered by the time-traveling creator of the Nietzcheans). The crew had only one un-altered human (until they started to get a bigger crew in later seasons), and it was mentioned a few times that more than 80% of humans have some kind of engineered genetics.
 * "Deconstruction of Falling Stars", the season 4 finale of Babylon 5, had a human from a million years into the future revealed as a trans-human Energy Being who uses an encounter suit much like the Vorlons earlier in the series did.
 * Jason Ironheart becomes one after an experiment at creating telekinetics turns him into an Energy Being.
 * The third season Blake's 7 episode "Moloch" featured one of these, although it was Justified Trope, more or less, since said being was the result of a computer simulation made flesh by an ultra-sophisticated replicator.
 * It's suggested (the crew can't really go look; finding Earth is one of the series' goals, though hardly ever really worked toward) that humanity is extinct in Red Dwarf due to the 3 million year difference between when Lister left Earth and the current time frame. They don't really know what happened, but in the first episode it is suggested that if 3 million years could turn a house cat into Felis Sapien, Lister compared to "modern" humanity might as well be the slime that crawled out of the primordial sea.
 * The various species of GELFs (Genetically Engineered Life Forms) the crew encounters are all of human creation, but they serve very much the same role in the plots that aliens would in a more conventional space opera.
 * Basically, every "alien" in Red Dwarf is a human creation, fast-forwarded three million years. Many shows have The Precursors; here, we're it.
 * The Star Trek: Enterprise episode "Terra Nova" has the Enterprise encounter a colony wiped out by radiation, and an English-speaking primitive group of underground-dwelling bumpy-skinned humanoids, all under a certain age. Guess what, they're . Why the Enterprise crew don't make the connection sooner is just par for the course for that series.
 * Star Trek: The Next Generation inverted this trope
 * The "ascended beings" in Stargate SG-1 - at least, the ones who were human before they ascended.
 * An episode of The Outer Limits has a group of college students board an ancient alien starship. When they land, they find a skeleton of a human-like figure with bat wings, which they assume to belong to the aliens who sent the ship. Then it is revealed that the planet is actually Earth in the future, meaning the skeleton belongs to a human who has either evolved or has been genetically modified to have wings.
 * of Fringe are revealed to be this, albeit coming from one possible future of humanity. Using their unique mastery of time, they are free to interact with the past (including our present).

Tabletop Games

 * Some role-playing-games use the term "Evolutionary Offshoots" for such creatures
 * The Therians from AT-43. They're more Well-Intentioned Extremists than villains, as they're the descendants of humanity, but found that the universe would collapse in a trillion years in its current state. To prevent this, they seeded worlds with life which would strip their homeworlds of resources, allowing their conversion into a gigantic Dyson sphere. All the other factions in the series were seeded by them.
 * As is befitting AT-43, they are also huge nerds. The MMORPG is the basis for their society, and forums are considered cities.
 * "Transhumanity" in Eclipse Phase is mostly composed of humanity and its descendants, though except for flats, almost everyone is genetically enhanced to some degree and virtually immortal. It also includes uplifted animals and A Is though, who are not that different from humanity anymore (and can slip into each other's bodies).
 * An early Dragon article for the Gamma World RPG (several editions ago, and no longer canonical) justified the unrealistic physical hardiness of its "pure strain humans" by revealing that they're descended from genetically-engineered superhumans. Untampered humans' descendants are all mutants; "pure strains" only think they're the original human type because they closely resemble the humans in ancient pictures.
 * Continuum plays this a number of ways -- every Spanner, whether Continuum or Narcissist has been at least partially uplifted by future technology to give them the ability to Time Travel. Aquarian humans from after 2222 AD or so are benevolent, slightly weird telepaths (and get weirder the further Up you go) as a result of the same sets of technology, while past 2400 the world belongs to the Exalted and the Inheritors. The Inheritors have apparently managed to colonise and fill the rest of the universe, so a portion of UFO sightings are spotting them taking a break en route to their colonies in the Earth's past (the rest are spotting them cleaning up someone's attempt to mess with causality and cause vigintillions of Inheritors to never have existed). The monstrous side of the trope is played straight by.

Video Games

 * The Abh from Crest of the Stars and the Androsynth from Star Control are both genetically engineered humans.
 * The Veruni of Wild ARMs 5 are believed to be aliens by the inhabitants of the Filgaia they conquered. However, it later comes to light that centuries ago they fled Filgaia by spacecraft and then returned a few decades ago. However, their alternate path of evolution has made them unfit to survive on Filgaia and they are dying out.
 * Also Wild ARMs, where the evil alien robots turn out to be robots from the future after mankind has replaced organic parts with machine parts.
 * Combine Overwatch soldiers are substantially modified humans touted as "transhuman" and the next stage in the human species' evolution, according to Dr. Breen, and are referred to by Dr Kleiner as the "post-human allies" of the Combine in one of his broadcasts. The Combine will uplift you to the next stage of evolution whether you like it or not.
 * The Rikti from City of Heroes are mutated humans from an Alternate Universe. They're disfigured to the point of being unrecognizable as human, but they also have advanced technology and Psychic Powers.
 * Each of the three factions of the Korean MMO RF Online are this: The Bellato are short Heavy Worlders, the Cora are space elves with psychic powers, and the Accretians are cyborgs with Landmate-sized bodies.
 * Lunarians from Touhou were humans that moved to the earth in ancient times. They also have the most advanced technology in the series, live on the source of Gensokyo's magic, and include a pair of Mary Sues that systematically defeat many of the main characters.
 * The Omar in Deus Ex: Invisible War.
 * in Mass Effect, although

Web Comics

 * The world of Drowtales contains both normal humans and "Rift Halmes", who have changed due to living underground.
 * Venusians in Triquetra Cats, using cybernetics and genetic manipulation to adapt themselves to Venus, humans from that planet end up looking like cyborg Grey Aliens

Web Original

 * Many, many kinds of transhuman aliens in Orion's Arm. Generally positive in portrayal.

Western Animation

 * The Gobots from Challenge of the Go Bots are descended from Human Aliens rather than humans per se, but they're still a race of Cyborgs.
 * In "End Sinister," the last episode of Aeon Flux,
