"If you can't build a better mousetrap, build a better mouse."The biological counterpart to Cyborging: instead of altering humans to add machine parts, the geeks in the lab-coats change the flesh, blood and DNA. Genetic Engineering and stem cell research opens new avenues in the way science and Sci-Fi writers can create modified humans to suit any environment. You could think of them as artificially created Mutants, but "artificially created" is the key to the definition. And we mean created on purpose, not by freak accident like being bombarded with gamma radiation or other exposure to Green Rocks. On the mild end, this can entail things that, if current medical science keeps trending the way it does in Real Life, may not sound all that fantastic in a few decades: limb grafts, biological prosthetics and less visible gene mod enhancements that make people smarter, stronger and better at stuff. Further down the fantastic scale you start to get genetic superpowers, quick and easy drastic cosmetic changes from plastic surgery on up (want green skin and spots? No problem!), extra limbs and stuff that makes humans look a lot more like aliens than most Human Aliens. Can be combined with Cyborging for even more body mod fun. Certain types of Functional Magic may accomplish the same thing but many or most of them are better listed under Mix And Match Creature or Hybrid Monster, and of those remaining, should be looked at with Clarke's Third Law in mind. Is a newer trope than cyborging because Genetic Engineering Is the New Nuke (and shares some but not all examples with it). Also see Organic Technology, LEGO Genetics, Magic Genetics, Superpowerful Genetics, Mix-and-Match Critters, Art Major Biology, Bio Punk, and its Super Trope, Transhuman.

Anime & Manga
- Appleseed has "bioroids", Artificial Humans with genetically suppressed aggressiveness.
- Ghost in the Shell: Stand Alone Complex also has a bioroid, Proto, in the second season.
- Claymores use something like Graft Flesh from D&D for reproduction.
- The Millennium Organization in Hellsing uses surgical procedures to turn Nazi soldiers into vampires in order to better their odds at world domination.
- Absalom in One Piece is a freakish mixture of animal parts all sewn to his previously normal human body. You can't see most of it normally except for his lion's mouth. Sadly for him, biology and physics don't work the same in this world, so Sanji is much stronger than the bear muscles comprising Absalom's limbs.
- Coordinators and Extended in Mobile Suit Gundam SEED and Mobile Suit Gundam SEED Destiny. The former are humans genetically engineered to be peak mental and physical specimens of the human race, the latter are ordinary humans turned supersoldiers through years of mental conditioning and carefully-administered drug regimens.
- In Guyver the entire business plan of the ChronosCorporation is to "optimize" humans into monstrous Zoanoids.
- In Wild Fangs, Syon is created in attempt to make more Marked Ones. Besides being created via artificial insemination, he was continually having pieces transplanted onto him leaving huge raw scars where the natural markings would ideally be.
- Tsukune and Hokuto from Rosario + Vampire are humans who have been infused with the blood of monsters, and have gained some of their powers—and some mental instability.
- Many Bishokuya from Toriko are infused with Gourmet Cells which cause mutations giving them special powers and limited Adaptive Ability. Eating food that is compatible with them will cause them to "evolve". This isn't without risk since Gourmet Cells burn energy at an alarming rate, forcing those who have them to be Big Eaters. A few people were born with Gourmet Cells instead of having them infused later, such as Midora.
- Chapter 259 reveals that the Earth itself was infused with Gourmet Cells by a meteorite. The "Human World" is the original Earth and "Gourmet World" is what the Gourmet Cells created.
- In Yu-Gi-Oh! GX, Kenzan's DNA was accidentally spliced with that of a dinosaur sometime in the past when he suffered broken bones at a paleontological dig, and doctors mended them with dinosaur bones at hand. This enables him to somehow access primal, bestial powers when angered or excited, at which point his eyes become reptilian and he can gain a serious Heroic Second Wind. It also renders him impervious to the corrupting power of the Light of Ruin. (Sure, it really doesn't make sense but little in the show does.)
- Snow White and Seven Dwarfs revolves around "tekigousha," people who've obtained special abilities (primarily of the Blessed with Suck variety) by undergoing human experimentation. Virtually every major character is a product of said experimentation.
- Rogue Trooper centres around the last surviving Genetic Infantryman out to avenge his comrades.
- In The Mighty, Alpha One Had been kidnapping humans for years and experimented on them to give them the same super powers as him. Most of them turned into monsters.
- In the story "Bats in My Belfry", in Tales from the Crypt, a man who was going deaf received an ear-canal transplant from a bat. The same back-alley surgeon who performed this impossible operation had previously given one of the protagonist's friends an eye-transplant from a panther.
- Iron Man foe Ezekiel Stane augmented himself to be a biological version of Iron Man. He can use his own body's energy reserves to fly and generate repulsor blasts, but needs to consume a very high calorie goo to avoid starving himself to death after using his powers. To use his full powers, Ezekiel also needs to wear a suit designed to vent excess body heat to avoid burning himself up.
- In Über, the mysterious "Wotan's Blood" kills and/or horribly mutates most people but can transform others into the superhuman "Ubers". Depending on the potential of the candidates and the follow-up activation procedures, the results can be radically different. The rarest and strongest Ubers are the "Battleships" who can wipe out dozens of lesser Ubers with ease.
- The two-parter Batman story Infection revolves around Batman having to fight two escapees from a governmental science lab who were infected with a genetically tailored virus created during the Cold War that induced this effect to create Super Soldiers. The infectees were given increased strength and durability, built-in guns that fired bullets of sharpened bone, specialised organs that let them cannibalise human corpses to replenish their supply of ammo, and programmed delusions that compelled them to "retake America from the Commies". As well as the ability to produce pustules that would disperse an infectious variant of the virus, allowing a single survivor to infect dozens, or even hundreds, of individuals.
- In Aeon Entelechy Evangelion before the First Arcanotech War there was a genefixing procedures that modified humans. After the Nazzadi joined, due to their existential angst by being an manufactured race with Fake Memories they put a stop to any transhuman experiments. By the time the fanfic starts, genefixing is slowly resurfacing.
- In Warhammer 40000 Trouble, all the (teen) humans are given Bio-Augmentation. Instead of painful surgery or something, they're only given drugs and manipulated diets, and they become stronger via Training from Hell and Level Grinding. The best result achieved when they're in puberty (14-20 years). Elites are those who can stand heavier training, therefore higher Power Levels. Result usually break into three categories:
- Soldiers = Simply stronger and faster (most people tends toward this, boys and girls alike). All of them Join Guardsmen.
- Sisters= Girls weaker than the female Guardsmen, but able to synchronize with Powered Armor efficiently (without Black Carapace).
- Operators= Incredibly high perception, G-tolerance, and motor control, resulting almost-instant Ace Pilot.
- In Mass Effect Human Revolution mankind uses this to Loophole Abuse around their self-imposed anti-cyborg rulings. The genemods given to the average Alliance soldier makes them "only" peak human, but more potent ones exist - Jules Leng, being The Dragon to the Corrupt Corporate Executive running the most advanced Mega Corp. in the trade, has bioaugs that grant him Compelling Voice, Deflector Shields, Healing Factor and Invisibility Cloak.
- The Headhunt: The Motta crime family has been known to get its soldiers genetically enhanced on independent fringeworlds like Adigeon Prime where such augs are legal. Dul'krah also reveals that his entire species is genetically enhanced to be resistant to disease and radiation and "able to subsist on materials that most would not even consider edible," which they believe dates back to the aftermath of their self-inflicted Apocalypse How.
- Runs rampant in No Gods, Only Guns thanks to unscrupulous MegaCorps experimenting on the human genome - with the side effect of inducing mental instability in a large part of the human population. The process is explicitly described as "pummelling their DNA into submission."
- Starting to come to the fore in Child of the Storm, with both the MCU and Mainstream versions of Extremis being referenced (the latter is a refinement of the former), as well as the Infinity Formula.
- Played with in Alabaster Orchestra, with Ichigo having his Shinigami side being purged from him after getting captured by the Vandenreich.
Films — Live-Action
- Repo! The Genetic Opera has the realistic version, the most fantastic being Blind Mag's hologram projecting eyes.
- And considering how she's essentially the mascot of the company providing all of the new and improved organs, it makes sense that she would receive the most cutting-edge products they have to offer.
- In The Bourne Legacy, Outcome agents are retrovirally engineered to enhance their physical and mental abilities.
- Successful bio-augmentation exists in the world of the Alterien series. In fact, many variations of bio-augmentation is what goes into the creation of super soldiers. Other uses go to treating civilians as well.
- Duumvirate has electroplaques, quadbracchalism, combustive gases, and other things as "extras". The new basic humans have regeneration, super strength, and super speed.
- The Vattas War series has "humods", modified humans that use combinations of biotech and cyborg tech in a way that they practically stand in for the series' Absent Aliens. A tongue that can check the authenticity of precious gems? Extra-sensitive tentacle hands? Colored skin? You can have all that.
- In Lois McMaster Bujold's Vorkosigan Saga books:
- The Cetagandans are extremely into genetic engineering on themselves. Especially the Haut caste.
- On Jackson's Whole we see body guards who have enhanced strength and reflexes, at the cost of shorter lifespans. They're also the ones who made Taura the super-soldier, and Baron Ryoval would make you a slave to satisfy any of your depraved desires, for a price.
- The novel Blood Music, winner of a Hugo Award and a Nebula Award, is a Gone Horribly Wrong example: a scientist creates biological computers, each potentially as smart as a human from lymphocyte cells then injects them into himself. They attain self-awareness. Chaos ensues.
- Along with rampant xenophobia, a rigid caste system, a hatred of nonorganic technology, and institutionalized, religious masochism, this is the Yuuzhan Vongs' "thing". Chopping off fingers or limbs to replace them with specifically-created animal bits is a sign of status; if their bodies then reject the new additions, it leads to a major drop in status.
- This trope is the foundation of Scott Westerfeld's Uglies Trilogy.
- In Orson Scott Card's "Shadow" series, a rogue scientist alters the DNA of 24 fertilized eggs to create superhumans, with a possible goal of replacing humanity. They're highly intelligent from an impossibly young age; the only downside is that they grow so large their bodies can't take the stress and they die by the age of 20. The experiment's only survivor is Bean, and he does his best to keep his children from inheriting it.
- Further toward the fantastic end of things, we have the Bred in The Sirantha Jax Series. They're engineered at birth to be better than average humans — faster, stronger, more graceful, more beautiful. They even have at least one superpower — regeneration.
- Tons of it in the Council Wars series, as part of the general Magic from Technology nature of the milieu.
- Used in the Honor Harrington series. The depiction is fairly realistic, with such things as the titular character suffering malnutrition when her Hyperactive Metabolism isn't kept fed. The series also features a fight against "genetic slavery".
- It's amazing how many fantasy stories let the protagonist to absorb his opponent's abilities simply by drinking their blood.
- In Spin there is the Fourth Age, extending one's life and allowing to install different abilities on the human.
- The Sauron Cyborgs in Jerry Pournelle's future history cycle are created through bioaugmentation rather than chop and replace.
- This is the Hat of the planet Prometheus in George R.R. Martin's "Thousand Worlds" short stories. Through genetic engineering, the Prometheans are bigger, stronger, faster, and mentally they are always "three steps ahead", to quote a Promethean character from "Nightflyers". It's theorized that they live longer than non-augmented humans as well.
- Greg Egan's Quarantine focuses heavily on neural mods that alter people's thought processes - for instance, Sentinel allows a person to stay focused and alert through long periods of inactivity, and Boss allows a person to play with their circadian rhythm, meaning that they can fall asleep at-will or set aside the effects of fatigue. The protagonist in particular used a mod that dulls emotions to keep the mind clear for rational/tactical thinking (standard issue for police officers) to not be bothered by his wife's death, which is implied to be a semi-common form of abusing mods. More conventionally, the book also mentions that most southern Australians have black skin to combat the destruction of the ozone layer.
- Rob Grant's Colony has backstreet grafters, who can (illegally) replace existing organs and add extra body parts. A prostitute offers one character a handjob with a hand with a vagina in the palm.
- Jeff VanderMeer's Finch features the Partials, people who have deliberately allowed parts of their bodies to be overtaken by beneficial fungus infections and replaced one of their eyes with a "fungus camera", in order to become Quislings for the Graycaps.
- Done with almost terrifying thoroughness by the "Change" syringes in Beggars in Spain. In addition to delivering the Cell Cleaner, which destroys any bearers of non-native DNA (from bacteria to cancer), it modifies the human body to be able to liquefy and absorb certain forms of matter, and adds organelles capable of photosynthesis and fixing nitrogen directly from the atmosphere. If mouth food is not available, a Changed person can lie on soil and in sunlight for half an hour and obtain all the energy they need. "You are now autotrophic."
- In the web-novel Domina, something called the "toy maker" lets people modify their bodies relatively easily. It's described as "like stem cells, but without the moral implications." The products are called "toys," and are split into cosmetic "cosmos" and functional "buffs." It's not limited to humans, either; the fey think it's funny to release augmented animals every once in a while.
- The Susan Gates novel Dusk, which centered on a girl engineered with hawk DNA
- In Robert Silverberg's story "At the Conglomeroid Cocktail Party", genetic engineering is such a common and casually-regarded thing in the far future that people actually hold "fetus parties" where they invite the guests to come up with the best design for the hosts' future offspring.
- "Pure" boys and some girls living in the Dome undergo "coding" (enhancing their speed, strength and intelligence) in Julianna Baggott's sci-fi novel Pure.
- In Roger Zelazny's Creatures of Light and Darkness, this is common on the human worlds, especially Blis, where we meet a wrestler with four arms, and Megra of Kalgan has such enhanced strength that she can only trust the strongest of men to survive her lovemaking.
- In Neuromancer Wintermute replaces Case's failing pancreas and liver with bioengineered ones that make him Immune to Drugs, he then spends much of the book looking for something that can get him high.
- In Robert Reed's Great Ship universe, the Remoras are constantly bombarded by interstellar radiation due to them living on the outer hull of the Great Ship, which causes rampant mutations. The Remoras use technology to cultivate the mutations into forms they consider useful or beautiful - such as being able to see further up the visual spectrum by replacing their eyes with photosensitive hairs.
- In The Mortal Instruments, Valentine unknowingly added angel's blood to Clary before she was born. He also added angel's blood to Jace before he was born, through the naivete of his birth mother Celine Herondale.
- In the Monster Blood Tattoo series, people do various forms of this; the most disturbing ones augment their senses to the point they have to wear special helmets to help direct things so they don't go insane from sensory overload. Unusually, this series is set not in the future, but in a world resembling a magical version of Napoleonic Europe.
- The Ultra Violets got their superpowers from accidentally being exposed to Helitropium, a substance capable of genetically altering any living thing on planet Earth.
- In A Confusion of Princes, Princes have a combination of this and cyborg parts.
- The Witcher has mutations such as faster reflexes, higher regeneration, more durability, higher tolerance to toxins, immunity to diseases and control over the body to a incredible degree (such as controlling the widening or shrinking of the pupil). However, this comes at the price of infertility. Also, most aspiring witchers die due to the horrible side-effect and high mortality rate.
- Neogicia, a Spin-Off novel of Noob focuses on Empire neogicians, who get this as a job perk. The First-Person Perspective protagonist is shown to have gotten the standard Super Strength, Hyper Awareness and much more rare Telekinesis.
- The Star Trek universe does not indulge in this to a great deal but it's reasonable to believe they have the technology for it, given that when someone needs to pass as, say, Romulan or Cardassian (or Cardassian posing as a human in one case), they can drop into sick bay for some easy plastic surgery and genuine pointy ears.
- The Federation banned it due to having the genetic engineering equivalent to a Robot War. Earth's early attempts created Khan and his supermen, superior in mind and body but too aggressive. Having been engineered to be superior to ordinary humans, they felt that they should rule the ordinary humans. They ended up starting the Eugenics Wars before being defeated and exiled as Human Popsicles. This causes a major problem for Dr. Bashir when he gets found out. Genetically enhanced humans were eventually dubbed "Augments".
- The United Earth had a ban on genetic enhancement before becoming founding the Federation, as mentioned on Enterprise. However, other species are not discussed. The question of whether a society that regularly used genetic engineering could join the Federation is not discussed.
- Bashir would later be charged with the care of a quartet of...slightly off Augments in "Statistical Improbabilities." Nicknamed the "Jack Pack" after their nominal leader, the four are able to postulate how the Dominion War will end... and then try and facilitate the Federation's surrender to prevent the needless waste of life.
- Despite the ban, one The Next Generation episode had the Federation allow a research station to develop an "ideal" human species. With long lifespans, improved intelligence, youthful appearance, telepathy, and an advanced immune system, they were the scientist's every dream. Almost.
- On the other hand, The Dominion, Federation's Evil Counterpart, is a huge genetic engineering society. Jem'Hadar were created from nothingnote , Vorta bred from some other form; and it's stated that The Founders were once humanoids but genetically engineered themselves into shape shifters. It is even supposed that their close-mindedness is the price they paid for their new body abilities.
- The Suliban on Star Trek: Enterprise obeyed a mysterious figure from the future, known to fans only as "Future Guy" since his identity was never revealed, in exchange for genetic upgrades.
- Babylon 5: Vorlons bioengineered various younger races to have telepathy. The Psi-Corps does extensive experimentation to allow telepaths greater abilities. Gill implants exist that allow the recipients to breathe in atmospheres they usually can't.
- A regular character in seaQuest DSV had himself implanted with gills to allow him to breathe underwater. Apparently, he is also able to survive at great depths.
- The Red Dwarf episode DNA had a DNA modifier which would allow a user to change their genetic structure. When the crew encounter the ship it was on, they find a man with three heads. Kryten accidentally becomes human, Lister becomes a chicken, a hamster and a foot tall "Man-Plus" (Essentially Lister crossed with RoboCop) and a mutton vindaloo becomes a mutant vindaloo-based creature that can only be killed with the application of lager.
- Heroes has a red formula that gives people a seemingly random ability.
- In Firefly, this appears to be the goal of the Academy, which gives people Psychic Powers, mental conditioning, and combat training to create superhumanly powerful assassins.
- In Supernatural the Special Children gain psychic powers after they were fed demon blood as an infant.
- In Orphan Black Olivier has had a tail transplanted onto himself, which he seems quite proud of. More generally, the neolutionists are believers in this.
- The villainess in the Doctor Who story "The Two Doctors" is an Androgum woman who has been "augmented" to the point where she has reached "mega genius level". However, both the Second and Sixth Doctors have misgivings about this, saying that, regardless of what has been done to her mind, the fact that Androgums are inherently treacherous and self-serving cannot be altered.
- In Mortasheen, as you level up, you can improve your Mons via this.
- Warhammer 40,000:
- Space Marine recruits go through an extensive and extremely taxing series of implantations of extra organs that cause massive physiological changes. The process is detailed here.
- The Thunder Warriors, the Space Marines' predecessors, were augmented using a far less refined process with the details unknown. The Thunder Warriors were even stronger than the Space Marines and Custodes, but were also physically and psychologically unstable and had shortened lifespans, making them unsuitable for the Emperor's long-term goals of galactic conquest.
- The Custodes were augmented using a refined version of the same process that created the Thunder Warriors. While less powerful than the Thunder Warriors, the Custodes are still stronger than the Space Marines and have similarly extended lifespans, making them the most powerful warriors in the Imperium. The few known details revealed about the procedure show that it's even more extreme and difficult than the process used to create a Space Marine. As a result, each Custodes is a costly investment to the Imperium.
- Dungeons & Dragons has the "Graft Flesh" feat and several variations that allow the altering of a creature's biology.
- In the Dark Sun setting supplement The Windriders of the Jagged Cliffs, players are introduced to living "life shaped" items that could be implanted in living beings.
- Cyberpunk 203 X includes a sea-faring tribe that uses genetic manipulation instead of cybernetics.
- Shadowrun has bioware (biological implants that enhance the recipient's abilities) as well as genetic augmentations. They aren't nearly as cool as and more expensive than cybernetic implants, but they do cost less essence.
- The one that shows up all over the place, especially in the novels, is the Supra-Thyroid Gland. Better, stronger, faster... all in one easy operation. The side effect is fun, too.
- A common trope in the Star*Drive setting, especially for Thuldan characters.
- Magic: The Gathering:
- Take Bio-Augmentation, add a generous dose of Hollywood Cyborg and Body Horror, and you've got Phyrexia and a couple of spare livers.
- The Simic Combine has this as one of their premier products, allowing customers to add various augmentations with Cytoplasts (such as give a normal-sized human a giant's strength). Unfortunately Momir Vig had ulterior motives for these...
- In Hunter: The Vigil, The operatives of the Cheiron Group keep up with supernatural creatures by abducting them, cutting them apart, and grafting bits of what make them special into their own systems.
- The Skaven supplement Children Of The Horned Rat for Warhammer Fantasy Roleplay has several sections on body augmentation - either technological, using bionics or powered frames built by Clan Skryre and done willingly, or actually warping flesh (usually that of prisoners) and melding creatures with weapons or mechanisms to produce horrific shock troops as practiced by Clan Moulder. Moulder members also tend to "improve" themselves as well, with extra limbs or massively altered metabolisms, with roughly the same results.
- For a period, there was a Skaven-specific Gaiden Game of Rat Ogre Pitfighting on the Games Workshop website, dedicated to the deranged craft of Clan Moulder. The entire point of the game was to do this kind of stuff to your "pets" and hurl them against the other players.
- Eclipse Phase again. In this RPG, changing bodies is done so often that a body is referred to as a 'sleeve'; all it takes is for someone to extract your "Cortical Stack" (which makes a backup of your mind once per second) and plug it into a new sleeve. Most biological sleeves, aside from non-engineered humans (called Flats) are immune to aging, immune to all natural diseases including cancer, and can even regenerate lost limbs over time.
- In the New World of Darkness:
- The Cheiron Group in Hunter: The Vigil upgrades its agents with implants engineered from the supernatural beings it hunts. Demon eyes, vampire ligaments, werewolf brain tissue — it's all on the table.
- The Legion in Mage: The Awakening summon up minor Abyssal spirits to consume and replace parts of their body, starting with eyes or hands and working up to major organs. Full members of the legacy often even replace their brains — which, by that point, is probably an improvement.
- The Splicers in BioShock are this Gone Horribly Wrong, quick and easy gene modification for superpowers at the cost of sanity. The plasmids/tonics that cause the most mental damage are the cosmetic plasmids (which the player can't use), which were designed that way.
- Deus Ex has the protagonist, his brother and the two main antagonists equipped with "nano-augmentations". In the sequel, this technology is much more widespread.
- In the prequel, the vast majority of augmentation are still of the mechanical sort, as nanomachine-based augmentation isn't even being tested yet.
That said, a sidequest does reveal that bio-augmentation tests performed on infants (presumably not using nanomachines) was the reason Adam's body can accept augmentation without the use of any drugs, and the ending implies what was recovered of this technology from Adam's body was used to create the Denton brothers.
- In the prequel, the vast majority of augmentation are still of the mechanical sort, as nanomachine-based augmentation isn't even being tested yet.
- The Genome Soldiers of Metal Gear Solid are enhanced by gene therapy with the genes of Big Boss to have augmented senses and reflexes.
- The entire first game in the Solid series is a Deconstruction of gene therapy (among other things). The end of the game includes a character noting that having the genes necessary to succeed means nothing if you don't have the mentality. And Snake himself is supposed to be a living example: despite receiving "all the recessive genes" and being an inferior clone of Big Boss, he is perhaps the greatest soldier in the world.
- In Metroid, Samus gets this a lot. She first was augmented with Chozo DNA as a kid to help her survive on their planet after the race adopted her. Later on, she's also transfused with Metroid DNA to save her life after being infected by the X-virus.
- This happens quite a lot in Geneforge, as skill canisters manufactured by the titular Geneforge can enhance the abilities of anyone who absorbs their contents by re-writing their genetic structure. However, With Great Power Comes Great Insanity...
- EVE Online:
- The mysterious Jove race became masters of gene manipulation and other bioengineering, transforming themselves into emotionless, quasi-superhumans. It's since bitten them in the rear, as they suffer from a degenerate disease that threatens to wipe them out.
- The Blood Raider Covenant runs an ample research of improvement of the human body through transfusions of modified blood that, among other examples, grants its citizens reduced aging, improved inmunological system and enhanced physical fitness, making their troops rival even Sansha's Nation True Slaves in combat effectiveness. Combined with a populace-wide public blood transfusion system (which has its basis on their ritual of "Blooding", main axis of their cult, the Sani Sabik), the Covenant's citizens enjoy a far more healthy life than those of even the main Empires. Unfortunately for outsiders, that means they might get their ship captured and themselves dragged to "Blood Farms" for having their blood used for the rituals, research, or even nourishment of the Blood Raiders.
- Genetic enhancement is fairly commonplace in Mass Effect, but is strictly regulated by Council law. Enhancing existing abilities is legal; adding new ones is illegal. Alliance soldiers routinely undergo genetic enhancement upon entering the military, and almost all children are screened before or just after birth and provided treatments to fix genetic defects. In addition, there now exist "designer babies", children of the wealthy that were engineered from the ground up to be better than normal humans. In some places they're the equal of any other human, in others they're regarded as little more than property.
- Mass Effect 2 squadmate Miranda Lawson is one of these "designer babies", and shows why it's not such a good idea. You can also pick up a "krogan retrovirus" upgrade, which alters the genetic code in squadmate Grunt to increase his health.
- The SPARTAN-II supersoldiers, at 14, underwent a laundry list of enhancements that made them physically and mentally superior to all other humans—those that survived the process, that is. Even so, damage remains in that they lack interest (and, through implication, ability) in sex.
- The list of enhancements to SPARTAN-IIIs is even longer, especially Gamma Company after their instructor, a SPARTAN-II, got tired of watching his students from previous companies get slaughtered in suicide missions and decided to add a few illegal enhancements to make them highly resistant to pain.
- The SPARTAN-IVs have somewhat less extensive augmentations, due to being modified as adults, but they can still do things like breathe methane for an hour.
- In the Compilation of Final Fantasy VII, various kinds of Super Soldiers are created via bioengineering and ruthless human experimentation.
- The most extreme case is Sephiroth, who is technically human, but with truly bizarre DNA since he was altered in the womb with Jenova cells and infused with mako energy.
- Genesis and Angeal from Crisis Core were products of Project G (a less successful Shinra research project that competed with Project S which produced Sephiroth) which also involved the use of Jenova cells and mako in developing fetuses.
- SOLDIERs such as Zack Fair and experimental subjects such as Cloud Strife are the result of modifying humans with both Jenova cells and Mako.
- Vincent Valentine was originally human, but was modified by both Hojo and Lucrecia Crescent into a deadly shapeshifter.
- Also from Dirge of Cerberus, the Deepground soldiers and Tsviets were results of various bioweapon experiments.
- The Final Fantasy franchise actually first utilized this trope in Final Fantasy VI, where The Empire bio-engineered Kefka and Celes to be magic-wielding Super Soldiers by implanting the genes of magical Espers. The process turned Kefka into a Psycho Prototype Monster Clown, but it was refined in time to give Celes magic without any downsides (though a cut plot point from the game would've made Celes unstable as well). Then she proved just as problematic as Kefka, but for different reasons.
- In the expansion pack to XCOM: Enemy Unknown, called Enemy Within, you have the option to upgrade your troops with gene mods to increase their combat potential. The modifications include, among others, increased muscle density, which allows them to jump to rooftops, a secondary heart, which prevents them from dying instantly when critically wounded, and mimetic skin, which let's them blend with the environment.
- Civilization: Beyond Earth: The Purity affinity is nominally anti-transhuman, but still partake in some basic genetic modification to improve lifespan and resistance to disease. It is the Harmony affinity, however, who take genetic modding into transhuman territory, incorporating alien DNA into their own and allowing them to empathise better with alien lifeforms and breathe otherwise deadly Miasma. High-tier Harmony foot-soldiers are basically Human-Alien hybrids.
- In Drowtales this is what the all-female Jaal'darya clan is (in)famous for. Well, this and Organic Technology.
- Spacetrawler: Yuri gets part of an Eeb brain implanted into her own, in order to gain greater technological understanding and limited telekinesis. And she gets cat ears, because she wants to be a Cat Girl.
- The K-Series soldiers in Elf Blood were designed before birth to have bodies ultra-compatible with Magitek implants. They were quite successful.
- In Jet Dream, Virus-X gives T-Girls enhanced strength, agility, and endurance in addition to its most obvious effect.
- Many characters in Schlock Mercenary get various strength and resiliancy boosts, due to their occupations as soldiers or mercenaries. More than a few characters end up getting full-body makeovers (turning a very runtish character into The Big Guy, for example). Later on, some characters learn too late that this process can turn them into unwitting bio weapons.
- Among The Chosen has quite a few heavily modified characters, but the technology tends to be so advanced as to blur the line between this and Cyborgs.
- This is the point of Pelvanida Base in Darwins Soldiers.
- In New Vindicators, this pops up with the Primes, man-made Neo-Sapiens (or super powered mutants), with powers of their genetic donors (though not always willing). In one case, cunning terrorists buy samples of this Prime technology and have it used by their duplicating leader to impregnate several women-leading to supers not only with doctored in super powers, but the man's own duplicating power as well.
- The Bioborgs of Orion's Arm.
- The Coalition soldiers (Ourkind) and several of the protagonists are this in Unlikely Eden.
- This is a common way of gaining superpowers in the Global Guardians PBEM Universe. Lord Doom even bio-engineered a raft of children to serve him as super soldiers.
- Whateley Universe: It's how Delta Spike went from a nerdy teen inventor to a super-strong energy blaster with the Most Common Superpower. She was experimented on by the dreaded Dr. Pygmalion. The doc's other experiments have all that, plus they are his mindslaves.
- Happened to the Architect in 1943 at the hands of Nazis, but the actual events of this time period take place on a different storyline called Upworld, Downworld. He was part of a highly unstable project by Nazi Germany to create a Super Soldier race of Nazis. Because of the danger this would theoretically pose to human lives, they used prisoners in the concentration camps. They infused demonic steroids within his body. The result augmented his muscular strength and turned his bones into a kind of living metal. Naturally after discovering his new abilities, he killed the people who slaughtered his family and then escaped.
- Planet Shield from Phaeton do this all of the time, though its mostly done with mindless clones who they then control with remote stations.
- Panacea of Worm has this as a superpower. She can exert complete control over the physiology of any living thing she touches. She mostly uses it to heal people, but the possible applications are pretty much endless.
