Fetus Terrible

Go To
Cain at least had the patience to be born.
Cameron: What happened?
Kim: I was scanned. The woman in the waiting room...
Cameron: She scanned you?
Kim: No, not her. Her child. Her unborn child scanned me.

The only thing creepier and more dangerous than the Enfant Terrible. The Fetus Terrible hasn't even been born yet, but will become The Antichrist or a demon prophesied to bring about The End of the World as We Know It or just wreak havoc once it escapes from its womb. The woman carrying this (often literally) hell-born spawn is usually an innocent, unwittingly impregnated by the Devil himself, and the other characters have to race to prevent the birth or stop the child from becoming the ultimate Enfant Terrible. Occasionally this can result of a perfectly normal pregnancy Gone Horribly Wrong pre or post conception, where the issue can be a mutant, Hybrid Monster, Undead Child or some other abomination. This trope can also overlap with Womb Horror, especially if the mother knows what's growing inside her.

Worth noting, not all examples are "evil", several are more among the lines of a Non-Malicious Monster.

Sub-Trope of Superior Successor, in cases where this isn't usual for the species.

    Anime & Manga 
  • Envy's true form in Fullmetal Alchemist is one, though borders on Ugly Cute.
  • Berserk:
    • After being raped by a newly-demonic Griffith, Casca gives spontaneous birth to one of these, which is actually the unborn child of her and the protagonist Guts, who was conceived as a normal baby but was corrupted by the aforementioned rape. It's hideously malformed, teleports away if threatened, and has a certain amount of control over the demons that constantly come after her. However, it's only terrible in appearance: the thing is apparently mindless, yet drawn to its parents like all children, and is willing to protect its mother. Eventually it merges with an egg-bodied demon, and Griffith is reborn through it.
    • Ganishka's demon soldiers, which are created by dropping pregnant women into a pool of liquid from captured Apostles and then burst from their mothers' stomachs Alien style, could count too.
    • Trolls breed by capturing and raping human women. After a short amount of time, the woman's stomach explodes and a group of baby trolls emerges from her bloody corpse.
  • Yuca Collabel from Immortal Rain resurrects himself this way. Specifically, after his surrogate mother is unwittingly artificially inseminated with him, he rapidly grows to term in two months, causing his mother's stomach to get so huge that she couldn't walk. Why does she get so big? Because he's already aged to the form of a prepubescent boy in utero. Unsurprisingly, when she goes into labor, instead of taking the usual route, he just bursts out Aliens style.
  • Hao from Shaman King. His regular rebirth through conception is treated as an Anti-Christ thing by his clan. They have a special 'kill the infant' thing around the time of the Shaman Fight because one of them will be him.
  • Pinoko in Black Jack started out as a fetal mass of underdeveloped flesh with psychic powers, encrusted as a huge parasitic tumor in the body of a woman (of whom she would've been her twin). Black Jack took pity on her as she wanted to live at all costs, and finally made her a doll-like body.
  • In Jin, the eponymous character is sent to the past by a horrifying fetus. Before the surgery, it's spent forty years in another man's brain, apparently drove him crazy and now it can telepathically contact (or rather scream at) Jin when he's miles and years away.
  • The A.I.M BURST from A Certain Scientific Railgun. It is the collective sorrow and despairs from the low-level Espers that used the Level Upper. Although it's not a human born fetus, it certainly qualifies for the terrible part. It's also the first arc's Final Boss.
  • In Chapter 49 of Hyde and Closer, we get a story about five people trapped in a tunnel: A business man, a wealthy couple, a policeman and a pregnant lady. The story basically tells how each one of them die one after another because of some creepy accidents. The catch is during the time they are trapped in the tunnel, the policeman was giving reports about how many people were still alive. He always gave the right number, but he always forgot to count one of them, the unborn child. The unborn baby was so furious for not being counted that he created those accidents to kill the people that were excluding him. In the end, he crushed his own mother under a rock and still managed to survive. Ouch.
  • The Watahiko in Mushishi. They're a fungus-like type of mushi that infect a pregnant woman, kill her developing child, and take on its form. If that's not enough, they multiply and have a Hive Mind.
  • Jinchuuriki in Naruto are often this, or at least regarded as such.
  • Arguably, Miaka's unborn child in the 3rd Fushigi Yuugi OVA counts as this, as it leads Mayo to the fake Suzaku. Subverted, however, because the rest is all Mayo's doing... and eventually allows her and Miaka to summon the real Suzaku.
  • In Descendants of Darkness, Hisoka's mother Rui has been pregnant for at least two years with a sort-of demon god.
  • In Magical Girl Lyrical Nanoha Striker S, all twelve Numbers bear a clone of Jail Scaglietti in their wombs. If he dies, a clone of him with all of his memories will be reborn and it will grow instantly into an adult. It's also Parental Incest.

    Audio Plays 
  • We're Alive has a type of Elite Zombie called "Little Ones." Turn out these Little Ones are actually the "grown up" fetuses of infected pregnant women that were fed massive amounts of growth hormone while in utero. The results were baby zombies that grew at massively accelerated rates and became giant killing machines in a matter of months.

    Comic Books 
  • Half of all comic-book pregnancies. Most notably, that of Donna Troy. Donna's friend and fellow Titan Raven is one of these, which is why her mom was spirited away to Azarath and allowed limited at best contact with her daughter. How well Raven can resist her "daddy's girl" tendencies determines which side of the Heel–Face Revolving Door she's stuck on for a story arc.
    • The worst would have to be Ms. Marvel in The Avengers, who got spontaneously pregnant, went through hyper-accelerated gestation, and gave birth to a child who rapidly grew into an adult and mind-controlled her into being his lover. Not only is it squicky almost beyond description, it's nigh-unfathomable how this got past, well, anyone in a Comics Code approved book in 1980.
    • The same thing happened to Power Girl during Zero Hour: Crisis in Time!; just replace "rape" with "incest", as the father was revealed to be her grandfather, Arion (in Post-Crisis continuity). The baby grew up to become Equinox, who promptly defeated Scarabus, disappeared, and was never seen nor mentioned again.
  • One Big Bad of X-Factor was Haven, who sought to bring about the foretold apocalypse today instead of waiting for it to happen on its own after still more centuries of human suffering. She was led to do it by visions sent to her by "him," but never elaborates upon just who "he" is, though you figure she's talking about God. She's not: she's pregnant, and "he" is her unborn child and the true source of her power.
  • One of the main characters in Lucifer was impregnated by a pack of cards. With twins. One of which she managed to kill while it was technically unborn, the other took her hostage until she negotiated with it.
  • Cassandra Nova, the parasitic twin sister of Professor Xavier was one of these. In fact, Professor X's very first act of superheroism with his Psychic Powers was to fight her while they were both in the womb. It turns out she was an astral parasite (known as a Mummudrai) who was Xavier's opposite: Every bit evil as Xavier would be good. She's since become one of the X-Men's top villains.
  • Jack Kirby created a one-shot character called Paranex the Fighting Fetus. No, really.
  • One of the most horrible stories in Hack/Slash had the slasher turn out to be a stunted murderous fetus who emerged from his obese adult twin brother's belly through a slit camouflaged between two rolls of fat. A very short story in the same series had a fetus carve its way out of its laboring mother with a knife, kill the attending doctor, and attempt to crawl into Cassie Hack while she was waiting for a gynecological exam. Hack promptly squashes it, but still... where did it get the knife???
  • In Fables, Snow White gets pregnant by the Big Bad Wolf and gives birth to six babies. What she doesn't know at first is that she actually had seven babies. The seventh child was a invisible being made of wind and wound up killing some people to feed itself. Things got better after that, though.
  • The end of Bio Apocalypse involves an epic showdown between a 50 mile high fetus and a space fleet armed with nuclear weapons. Really.
  • Pre-Flashpoint, Barbara Gordon was impregnated with one of these by Brainiac. It made her a Technopath for a while, until she had to abort it for her own survival.
  • Zigzagged with Rahne "Wolfsbane" Sinclair of the New Mutants and her son Tier. At first, it seems to be played straight; he develops at a freakish speed and kicks so hard that she needs an Emergency Power Up of Super Toughness to cope with it, and eventually she gives birth to him by vomiting him out of her mouth. Averted in that not only can all of this be explained reasonably (Rahne's a mutant, dad's an Asgardian wolf-spirit), Tier himself isn't evil.
  • The Boys: Billy's motivation against supers comes from the fact that his wife was raped then impregnated by one. The superpowered fetus then escaped her womb (via heat-vision then flying around, making it clear the Homelander was responsible) before Billy managed to kill it. Except he wasn't: his clone Black Noir, created to kill the Homelander if he went rogue, decided he'd had enough of waiting for his life's purpose, so he went around filming himself committing atrocities and sending the pictures to the Homelander, gaslighting him into going rogue.

    Comic Strips 

    Fan Works 
  • In the Godzilla: King of the Monsters (2019) fanfiction Abraxas (Hrodvitnon), the unborn children of the three Russian women who were non-consensually inseminated appear to be this. Whilst the human cast are unfortunately late to the realization, it's clear enough to the reader that the babies are related to Ghidorah and that Ghidorah itself has long-term plans for them.
  • Subverted in The Mountain and the Wolf, to the Wolf's clear disappointment: despite multiple Chaos-infused warriors having sex with Cersei several times a day for several months, her baby is born completely free of any Chaos corruption or mutation.

    Films — Live-Action 
  • Alien, obviously. There's a reason why the newlyborn is called a chestburster. It's made all the more horrible in Alien³, when Ripley is impregnated and you know that she will die, one way or another...
    • Prometheus picks up this trope from the previous Alien films and has a ball with it: Elizabeth Shaw recognizes right off that her pregnancy is abnormal, since she can't have children in the first place. Plus, it's grown far too quickly in the available time to possibly be human. Then she learns exactly what's growing inside her and immediately performs a Cesarean section on herself without adequate anesthetic; she's that desperate to get it out of her. The resulting baby/squid/facehugger hybrid proceeds to face-rape the Engineer and begin a very familiar cycle.
  • In The Astronaut's Wife, Jillian becomes pregnant after her husband returns home from a questionable space expedition, and it's suggested that the fetus isn't entirely human. At the end, we learn that she had Creepy Twins, and they're possessed by aliens, as is she, after the being inhabiting her husband's body transferred into her when she killed him.
  • A movie made in the mid 1990s called Aswang has this. Basically, Aswang are Philippine vampires whose tongues are abnormally long and are used to suck the innards out of sleeping people. The film's version plays on this as the Aswang in this American movie feed on unborn children, but the survivors of an Aswang attack become Aswang themselves. At the end of the movie, the mother is running away for her life, stumbles and is preparing to be killed by the house help when she feels something tickle downwards past her legs: It's an abnormally long tongue belonging to a baby Aswang.
  • The direct-to-DVD movie Born revolves around this trope, where the pregnant protagonist's demon fetus causes her to kill people so that she can give birth. Then when the baby is born (looking just like a human baby even though her ultrasounds show it as a gremlin-like creature), she's told that she has a chance of saving it — when it's said throughout the movie that its birth would bring hell on Earth.
  • Class of Nuke 'Em High: The killer mutant is technically Chrissy's baby, although it came out the wrong end.
  • The plot of Constantine (2005) revolves around a still unborn son of Lucifer who should prove to be many times worse than the father.
  • Cradle of Fear: After spending the night with The Man, Melissa begins hallucinating about the people around turning to her with monstrous faces and voices. Melissa goes to Nikki's house to seek help, then a creature bursts out of Melissa's womb and attacks Nikki, killing both.
  • A less apocalyptic but no less creepy version can be found in Dawn of the Dead (2004), in which a woman is bitten while pregnant and succumbs to the zombie plague. Her baby turns into a zombie fetus and is later born in a very gory scene.
  • Dead Night: Implied to be the main antagonist of the film, a woman is shown giving birth to one of these in the movie's opening. It flexes out her midsection in ways often seen in this trope.
  • The ending of The Doll (2017), after Sanaa has destroyed the evil demon Creepy Doll, has her go to her obstetrician for an ultrasound, only to see the doll's face on the fetus.
  • The third act of The Fly (1986) involves, among other things, the possibility that Veronica is carrying a mutant child, since most of her relationship with Seth came after he accidentally spliced himself with fly DNA. In a memorable Nightmare Sequence, she imagines herself giving birth to a giant maggot. For his part, Seth is against her intentions to have an abortion because it's possible that the child is fully human, and thus the last remnant of his own dying humanity, and in the climax he attempts to genetically fuse himself with her and the unborn child to save himself and create "the ultimate family". (The film ends without resolving this plot thread, so the B-Team Sequel The Fly II is about the Spin-Offspring, who turns out to be a good-hearted Uneven Hybrid.)
  • The movie Grace is about one of these. A mother survives a car crash, but her fetal daughter is killed — however, she insists on carrying to term. She does, and the baby is born seemingly alive... except that she bruises in sunlight, and has a thirst for blood.
  • It's Alive: The first thing that the baby does when it's born is slaughter the attending medical staff. And in the sequels, the creatures get even more horrific...
  • A particularly creepy example happens in Ju On: The Grudge 2. The protagonist, Kyoko, is pregnant at the beginning of the film, only to lose her unborn child in a car crash caused by Toshio. However, later in the film, after a visit to the hospital, she discovers that her baby is somehow still alive. How can this be? All is revealed at the end of the film, when she gives birth to some dreadful, unseen thing, the sight of which causes all the present doctors to go insane and die horribly, while it shrieks inhumanly. Shortly after the adult spirit of Kayako crawls out of her womb, and, when Kyoko awakens from passing out, she sees her baby on the floor, tightly wrapped in a bloodstained piece of plastic. The finale of the film subsequently reveals that the child is Kayako reborn (or a child simply possessed by Kayako, depending on which fan theory you believe).
  • The God of Machines in The Matrix Revolutions has the shape of a baby's head. Any similarity ends there.
  • A Nightmare on Elm Street 5: The Dream Child has Freddy trying to turn the main character's unborn son into one of these, feeding the fetus souls to strengthen it, presumably intending to either make the baby into his agent, or possess it. In a nightmarish flashback to Freddy's own birth, he's also depicted as one of these.
  • The plot of the film Prevenge sees the main character's unborn child willing her to perform a Roaring Rampage of Revenge, although it is implied that this is almost certainly a case of Enemy Within.
  • Popularized by Rosemary's Baby, the entire plot of which is "an unsuspecting woman is impregnated with a half-demon to serve as The Antichrist".
  • Scanners: When Cameron and Kim visit an obstetrician who has been receiving shipments of ephemerol from Biocarbon Amalgamate, Kim (sitting in the waiting room) is painfully scanned, not by the pregnant woman who is the only other person in the room but by her unborn child. Ephemerol actually mutates fetuses into scanners, and is being prescribed to pregnant women to produce a new generation of scanners to be converted to Darryl Revok's scanner-supremacist cause.
  • The demon fetus in Seeding of a Ghost, who is an aborted baby who's brought back from the dead to wreak havoc. The same fetus later impregnates a woman to assume a humanoid form.
  • The final scene of Splice reveals that Elsa is pregnant by Dren's male adult form, and she's persuaded by the genetic engineering Corrupt Corporate Executive not to abort the whatever-it-is she's carrying, so that it can be studied alive.
  • Barbara Eden once starred in a film called The Stranger Within, where she plays a woman who's taken over by the alien fetus she's carrying. In the end, it turns out that several women were impregnated, and they all get whisked off into space by the babies' father(s). It becomes Harsher in Hindsight considering what happened to Barbara Eden's own child.
  • The main antagonist of The Suckling is an aborted fetus mutated into a horrifying monster.
  • Oskar from The Tin Drum never committed any acts from the womb but he did have the very eerie ability to understand everything going on outside (as well as remember it years later) and hate the world for it.
  • A 1991 movie titled The Unborn is all about this. A couple who have had fertility problems for a long time undergo an experimental in-vitro fertilization procedure in order to successfully have a child. At first, they're ecstatic to be pregnant. Unfortunately, the doctor who performed the procedure was experimenting on the infertile women to produce creepily intelligent, genetically modified babies.
  • Who Can Kill a Child? and its remake Come Out and Play have an ambiguous case in that the pregnant females in both films die believing that their fetus has killed them, but it's never proven.

  • Damien Thorn Jr in Omen IV: Armageddon 2000. The pregnancy caused his mother terrible suffering and she died giving rectal birth.
  • Isaac Bashevis Singer's short story, The Black Wedding is about a Rabbi's daughter who is married to a demon and is eventually killed from the inside by her fetus. This story has a Cuckoos Nest twist though, as it is possible to read the character as being crazy and only hallucinating that her boisterous husband and his community are demons, and her ultimate death is merely from normal complications.
  • Mordred Deschain in The Dark Tower — while in the womb he forces his mother to eat frogs. He also has four parents, two of whom are human (and two of the main heroes). The other two are the Big Bad and the gender-bending incorporeal sex demon who raped the aforementioned humans at various points in the story.
  • The Christopher Pike novel The Grave was about a young woman who is impregnated by one of The Undead and killed by being dumped in a freezer. She becomes one of the undead herself and it is revealed that the fetus she is carrying was specifically bred by a Mad Scientist to become the antichrist. But by the end it's revealed that the scientist has failed, being more a balance between good and evil who destroys the scientist and goes on his merry way. Oh, and this book was aimed at teenagers. Really.
  • In Black Legion, Bile's experiments aboard the Fleshmarket include his attempts at cloning the Primarchs, most of which ended up as horribly malformed, but nevertheless sentient fetuses capable of communicating through telepathy.
  • Damon Knight's short story Special Delivery features a couple discovering that their unborn child is a hyper-intelligent telepathic bastard (in the magnificent, not biological, sense), but when he's born, the abrupt change in atmosphere turns him into an ordinary infant.
  • In Paradise Lost, the personification of Death is the child of the angel Sin and her father, Satan. Her giving birth to him was so painful that it caused her to cry out "death", with the scream reverberating across the universe, and creating a child with the ability to destroy anything except for God. He subsequently raped her, resulting in a group of demonic dogs inhabiting her womb, causing her to exist in eternal agony. It's a weird, weird poem.
  • In David Shobin's The Unborn, a pregnant woman takes part in an experiment where she's hooked to a super-computer. The fetus begins communicating with the computer and controlling the mother through hormones. Much horror ensues, including a failed abortion attempt, and worries about the baby being some sort of monster when born. At the end the baby is born, and is perfectly normal, hence a subversion.
  • Renesmee from Breaking Dawn bears all signs of being this, seeing as she feeds only on human blood and shatters her mother's ribs, pelvis and spine — but once she's born (by gruesome vampire-tooth C-section), she ends up a shockingly well-adjusted Creepy Child.
  • Glen Cook's Dread Empire books have the Unborn, a creature created by Varthlokkur from the (yes, unborn) fetus of a pregnant woman who was murdered. Played with in that while the thing is immensely creepy to everyone around it, it's not really evil and is actually essential as one of the few beings capable of reliably using magic when all magical energy starts becoming unreliable.
  • In Richelle Mead's Dark Swan series, it is prophesied that the first-born child of the protagonist, Eugenie Markham, will bring about the end of the human world.
  • To avoid horrible spoilers, let's just say that this trope plays a plot-critical role in Otherland as the origin story of one of the major characters.
  • A Song of Ice and Fire has Melisandre and her shadow assassins. Every so often, she'll lie with Stannis Baratheon, who she believes to be her religion's Messiah come again; when one of Stannis's enemies needs to be killed, she'll get in close and give birth to something made of shadow that can cut through steel and bone like paper (as his brother Renly found out).
    • Mirri Maz Duurr believed that Daenerys Targaryen's child with Khal Drogo was this. So, she did something about it. According to the possibly exaggerated tales of the other women present, the stillbirth was hideously deformed, with scales and bat wings.
  • The novel Parasite Eve ends with the psychoactive child destroying everything around it as it goes through its birth phase before it is inevitably killed by male zygotes, which means that sperm hurts it.
  • The titular monstrosities of the short story "Eumenides in the Fourth Floor Lavatory", from Orson Scott Card's collection Maps in a Mirror, don't appear in an unborn state, but they look an awful lot like stillborn fetuses (with a fair amount of demon mixed in). The term used for them is significant: "Eumenides" are otherwise known as "Furies", and these freaks are the main character's punishment for Parental Incest.
  • Particularly powerful psychics in Julian May's Galactic Milieu setting often develop powers and consciousness in utero. Fury, the Big Bad of the series used his Coercive powers to corrupt several of the Remillard dynasty's children before they were born. Later on, the Well-Intentioned Extremist Marc Remillard's plan to boost human evolution would come unstuck when Fury's servants infiltrated the clinic where hundreds of unborn fetuses were being given metapsychic training and corrupted them all.
    • Subverted in the case of Jon Remillard. Sentient, aware, and superbly powerful from the first trimester, destined by genetics to become something thoroughly inhuman, he is the closest thing to a Big Good the series has.
  • Dean Koontz:
    • In Demon Seed, the sapient computer Proteus IV is unable to experience true life himself, so he settles for using Susan's ovaries and womb to produce a perfect human child that will have his personality. In the original 1973 novel and the film based on it, Susan initially wants to kill the thing she helped give birth to; however, when she finds that Proteus's child has been genetically tailored by Proteus to physically be identical to her dead daughter, she appears to accept it. In the 1997 revised version, she does kill the far-less-human-looking avatar.
    • In his short story We Three, two brothers and sister, gifted with immensely far-reaching psionic powers, kill the entire human race. After that they beget a baby via Brother–Sister Incest — and the baby, still in utero, proves to be stronger that they three combined. And there's a strong possibility that the baby is a hermaphrodite, so it won't need the three protagonists after birth...
  • In K.A. Applegate's Remnants series, there is "The Baby", born during the 500-year space flight and controlling its mother Tamara through a psychic connection until she becomes a mere husk of her former self.
  • Used twice in The Darkglass Mountain Trilogy. The first, nearing full-term, Gorgrael eats his way out of his mother in the prologue, and in the third novel his nephew, Dragonstar Sunsoar, orchestrates his elder brother's kidnapping by Gorgrael from within the womb.
  • Jean-Baptiste Grenouille, the protagonist of Perfume: The Story of a Murderer, whose mother, as all characters who encountered him, died shortly after giving birth. Admittedly, she thought he was stillborn and decided to just throw him away with the debris of cleaning fish, but Grenouille emitted a piercing cry, and his mother was tried and executed for attempted child murder.
  • Ben Lovatt from Doris Lessing's The Fifth Child. Hariett Lovatt and her husband have a really great family of six, but Harriet's fifth pregnancy is a nightmare — she feels like the fetus tears her apart from inside and is consumed with pain and exhaustion. Ben, when born, is a most unusual and frightening kid whose presence ruins the family.
  • In Harry Potter and the Deathly Hallows, Voldemort's soul is described as looking like a horrific, shriveled, bleeding fetus. The reason is because making his Horcruxes has brutally torn and maimed his soul beyond repair. According to Word of God, Voldemort's final fate is to lie in Limbo between life and death for eternity as that shriveled, semi-conscious fetus, never living in the physical world but never moving onward into the comfort of death.
  • Brought up and explicitly feared in Tales of Kolmar. A dragon was turned into a human and married another human, which was prophesied to result in monster children and later a world brimming with demon fire with nothing to stop it. When Lanen got pregnant this pregnancy almost killed her several times, since the mingling of such different kinds of blood was hard on her body, but ultimately the trope is subverted.
  • In Waging Good by Robert Reed, the Earth's atmosphere is full of a variety of deadly nanomachines and tailored viruses after losing a war with its former colonies on the Moon and beyond. One type of artificial virus targets unborn children, mutating them into hellish abominations that hide poison factories in their stomachs or bladed monsters which try kill anything they see as soon as they are born. Because of this, Earth has "Jurors", people who test any newborn children as soon as they pop out. If they appear subverted, the Juror crushes their head against the nearest wall or table.
  • The Skyscraper Throne has Reach, King of the Cranes, an Eldritch Abomination who tears down the city and all the spirits within it as part of his attempt at being born.
  • In The Mallorean, Garion and company come across a temple in which a woman is giving birth. The father is the demon lord Nahaz. Neither child nor mother survive.
  • In Cassarabia, a neighboring imperial power from the Jackelian Series, this trope has actually become industrialized, as sorcerers known as "womb mages" use magical genetic engineering to produce new life forms that are gestated inside female slaves. These unwilling "producers" seldom survive more than a few years' of forced surrogacy, as the resulting artificial life forms are often much larger than any human adult, let alone a human infant: some "producers" are kept in nutrient vats to sustain their pregnancies, and have ribs and pelvic bones surgically removed to accommodate their over-sized pseudo-offspring.
  • Whateley Universe:
    • There's a classic example in a Lovecraftian sense. A woman whose ancestry isn't all human is made pregnant by a demon whose parent is Shub-Niggurath. The unborn child is predicted to be a powerful demon whose progeny will wipe the earth clean of humans. The mother is killed. Subversion: the mother is killed over twenty years too late, and the child grows up apparently human until his death. At which point it comes back to life and fights like hell not to be turned into the predicted demon. Currently in this universe, said character is one of the heroes. So far.
    • In Buffalo Gal Won't You Come Out Tonight (Ch 4), Debra is spiritually impregnated by one of Unhcegila's sons. When her spiritual abortion is discussed:
      "If she doesn't do this, she will die. The spawn of the serpent-creature will eat their way out of her, killing her in an agonizingly painful, slow death. She will die in the dream world, and she will die in the real world. Before she dies in the real world, though, she will be driven mad by what is happening to her." She looked at me with a level gaze. "You have no choice. She must take the medicine, and you must incant the spell I tell you if you wish to save her life."
  • Fëanor of The Silmarillion is an example of the "normal pregnancy gone wrong." He was so incredibly Hot-Blooded in the womb that giving birth to him depleted his mother's life energy—elf mothers pass part of their own living spirit into their children and Fëanor had all of it. She didn't resent him for it, but she was so spiritually exhausted that she passed away shortly into his childhood. Fëanor went on to become the mightiest and most skillful elf whoever lived—but also the most vainglorious, selfish, and hubristic one too.

    Live-Action TV 
  • Angel:
    • Cordelia becomes pregnant and possessed with a Fetus Terrible twice. If you count the "eye-in-the-back-of-the-head" thing, three times. It was even lampshaded.
    • Played with in the pregnant Darla storyline. It was written for a few eps as though she was pregnant with something terrible, although it was ultimately subverted.
  • Phoebe on Charmed (1998) becomes pregnant with Cole's child (conceived while he was possessed by the Source, and was thus destined to become the ruler of the underworld if born). The kid is able to make Phoebe throw fireballs, force her to shove Paige out of a third floor window and turn fruit into raw meat all while still in the womb. Ultimately, the fetus was magically transferred to the Seer, who, unable to handle the sheer power it had come to develop, exploded violently enough to take down the entire Infernal Council with her.
  • Game of Thrones: Played with. Mirri Maz Duur considers Daenerys Targaryen and Drogo's unborn son Rhaego this. He is prophesied to become 'The Stallion Who Mounts the World.' After Dany resorts to blood magic to save her dying husband, something happens in her womb, and the child is stillborn with reptilian features and wings.
  • Only Fools and Horses parodied this with the birth of Del Boy's son, Damien. When Rodney discovers the name to be given to the child, he is tortured by fantasies and nightmares that the as-yet-unborn child will grow up to be an evil, manipulative Antichrist. Of course, the boy is nothing of the sort, but this doesn't stop Rodney from reading far too heavily into the small child's rebellious antics.
  • There is a Colombian Telenovela titled Me Llaman Lolita where the heroine fell in love with the male protagonist since she was in her mother's womb, and her feelings radiated to her mother, leading to a series of tragic situations. Granted, she's not evil, but the whole premise is squicky as hell.
  • Let us not forget the long, drawn-out story arc on Xena: Warrior Princess in which Gabrielle is impregnated by the demonic god Dahak.
  • When Gail is pregnant with Lucas Buck's child in American Gothic (1995), she sees the baby as this during her ultrasound.
  • Supernatural: Kelly Kline's Nephilim child, the son of Lucifer, is a being so powerful his birth outright kills his mother, and before his birth both angels and demons consider him a borderline apocalyptic threat. Supernatural puts a spin on this by having Jack be a rather nice person who doesn't really want to hurt anyone, much to the disappointment of his father.
    • Jack then proves himself to be the ideal replacement for his malevolent grandfather God AKA Chuck Shurley, after he and the Winchesters figured Chuck is a sadistic jerkwad fanfic writer that is torturing everyone in the multiverse for his personal amusement as he only sees them as characters of the story he writes, he loves downer endings at the expense of the people he tortures and he never cared about anyone interpersonally.
  • In the Torchwood episode "Something Borrowed", Gwen gets her Face Full of Alien Wing-Wong at her Hen Do (Bachelorette Party) and she is tracked by the genetic mother of the fetus who wants to rip Gwen apart to get her baby. The trope predominantly comes from Gwen and Rhys's parents thinking she's going to have their grandkid juxtaposed with Torchwood trying to figure out how to kill the fetus.
  • Lost's Aaron may grow into something terrible, depending on who you ask about the woman raising him.
  • Malcolm in the Middle
    • Played with when Dewey is encouraged by his unborn brother to make mischief.
    • Another example is in a flashback when Lois is pregnant with Reese, and he kicks so hard that it's clear that he already has a nasty violent streak.
  • Subverted in the Star Trek: The Next Generation episode "The Child", in which Deanna Troi becomes mysteriously pregnant, which makes some people very nervous, but it's really just a friendly alien wanting to learn about humans by incarnating as one for a short time.
  • One episode of ReGenesis involves a baby specifically bioengineered by terrorists as a purpose-built carrier of a deadly, contagious hybridized plague, and implanted into the fetus of an unsuspecting mother in an attempt to bring about The End of the World as We Know It.
  • Ghost Whisperer's Melinda is pregnant, and the Other Side has told her that her son will have even more powers than her, which will presumably draw unsavory spirits to them.
  • The 4400: In "White Light", the unborn Isabelle uses her abilities to injure Jordan Collier in such a way that Shawn is unable to completely heal him more than a year later.
  • The X-Files:
    • A likely explanation for the events of "Aubrey" is that detective B.J.'s unborn child is taking after its great-grandfather.
    • The episode "Terms of Endearment" is all about a demon who's trying to father a child that isn't this. He just wants a normal human baby and marries women and then kills them when they inevitably give birth to demon babies. (He kills the babies, too.) Unfortunately for him, he eventually marries a woman who wants a Fetus Terrible.
  • Riget: In the haunted Danish hospital, Dr. Judith Petersen's fetus develops much, much, much too fast. The mysterious father has disappeared, and her new boyfriend tries to convince her to abort the FT. However, the child gets born towards the end of the first season, just when they try to carry out the abortion, and we follow its trials and tribulations throughout the second season. It turns out that the child isn't evil at all. The father, on the other hand...
  • In American Horror Story: Murder House, Vivian is pregnant with a demon spawn.
  • In season 9 of Stargate SG-1, the Ori impregnate Vala with the Orici, basically their version of the Antichrist. As Vala herself put it:
    Vala: Let's get something clear. She's not my daughter, Daniel. The Ori impregnated me against my will and forced me to bring her into the galaxy. I was an incubator. A shipping crate. And nothing more.
  • In one of the more nightmarish episodes of Ultraman Ace, Yapool curses a pregnant woman by transforming her unborn child into a monster called Mazarius. To make matters worse, after Mazarius is "birthed,"note  Yapool transforms the pregnant woman into the source of the creature's life force meaning the only way Ace can kill Mazarius is to somehow lift the curse of its "mother".
  • Zigzagged in the original V (1983) franchise, as Robin's pregnancy by a Visitor at first looks like this trope, causing her to crave raw meat and nearly killing her when an abortion is attempted. She gives birth to twins: a daughter who looks human, then reveals a reptilian tongue and poison spit, but grows up to be one of the good guys; and a short-lived scaled son who's the carrier of a toxin that becomes the heroes' chief weapon against the alien invaders. So he's a Fetus Terrible for humans in looks and for the aliens in physiology.
  • Discussed in The Walking Dead (2010). Lori briefly expresses concern over what would happen if she suffered a miscarriage, and her unborn child turned in the womb.
  • One of the unsubs on Criminal Minds was a teen boy who claimed his mother turned him into a monster by hating him since he was born. She eventually admits to hating him because she "was pregnant with twins, and then [she] wasn't." The show does point out that he's too young to be diagnosed with psychopathy, so it's unclear who's right (whether he committed his first murder in the womb, or whether his mother's mistrust of him drove him to rise to her expectations).
  • Ben Chang on Community claims to have eaten his twin sister in utero. However, it is also possible that he just made this story up, which seems just as likely given the source.
  • In Evil (2019), Eleanor is in the ninth month of her fraternal twin pregnancy, and comes to believe the male twin is malevolent, and requests an exorcism. She is initially rebuffed by the church, as an exorcism on a womb is highly unorthodox. Later, while attending mass, she appears to suffer a miscarriage, but her son is shown to still be alive. However, her daughter now mysteriously no longer appears on the ultrasound. Eleanor's doctor attributes this to Vanishing Twin Syndrome, whereby one twin absorbs the other. However, he conveniently ignores that this should only be possible about 12 weeks into the pregnancy, not 9 months (nearly-born babies don't absorb eachother). Eleanor, horrified by the whole ordeal, attributes this to her son eating her daughter. David later arranges an emergency exorcism, but she gives birth before it can be completed, to a seemingly-healthy baby boy.

  • Abigail, in the King Diamond album of the same name, possess her mother before being born. She is also an example of Express Delivery.
  • :wumpscut:'s Womb is about the Fetus Terrible delivering a Break Them by Talking to the mother.
  • Nirvana: Inverted and subverted. Cobain was fascinated by the concept of birth and evoked the imagery often in his work. The album art of In Utero also references childbirth by showing the inside of a female body and imagery of fetuses. However, to the audience this all comes across as being nauseating and creepy.
  • The Cover of ASP's Requiembryo shows the albums Big Bad, the Black Butterfly, as an Embryo. Nothing is said about this on the album.

    Myths & Religion 
  • The creation myth in some American Indian cultures features the Good Twin and the Evil Twin. The Evil Twin is evil from the womb, and typically kills his mother trying to get born too quickly. He goes on to create death, disease and the Rocky Mountains.note 
  • Esau and Jacob fighting in Rebekah's womb and causing her lots of trouble... Esau in particular.
  • All fetuses, if the concept of original sin (with no sufficient concession to a hypothetical age of reason) is combined with that of ensoulment occurring before birth (hence limbo as a receptacle not just for unbaptised infants but also for fetuses aborted or naturally miscarried).

    Tabletop Games 
  • Ye olde ever relevant Dungeons & Dragons calls these little nasties "Unholy Scions" in the supplement "Heroes of Horror", giving the fetus a +6 intelligence bonus while still in the womb (the rough equivalence of taking an animal and making it a slightly stupid person, or of taking an average person, and making them a genius). Comes with a no-save allowed charm effect on the mother.
    • The Atropal is a DnD monster which looks like a giant fetus. It's technically supposed to be a stillborn god, though, and is undead, floating around outside of a womb, and in the 3rd Edition was technically unkillable due to a rules loophole. If killed, some of its chunks had a chance to eventually come back again as an Atropal Scion.
    • Legends state that a hag can switch her unborn child for that of a human female. They further claim that any mother who brings a hag-child to term will be slain by her.
  • This is a motif for around 80% of Zombie Spawn in Mortasheen, which mainly comes from the fact that they are the horrifying results of two zombies copulating.
  • The first edition of Werewolf: The Forsaken has the unihar, or "ghost children," which are created when two werewolves have a sexual relationship and the female gets pregnant. At birth, a twisted malformed spirit emerges and flees into the Shadow Realm, waiting to grow more powerful and exact revenge upon its parents. Averted in 2E, wherein the product of two werewolves is simply almost certain to be a wolfblood likely to undergo the First Change.
    • In the predecessor, Werewolf: The Apocalypse, most werecreatures are forbidden from mating with each other since the offspring will be deformed from inbreeding, and are commonly known as Metis. As Metis are born in war form and don't gain the ability to shapeshift until they're about 3 years old, their birth usually kills the mother. But while werewolf Metis are simply Wangsty outcasts, the werelizard variety are always stillborn and become evil, twisted spirits.
    • For another Apocalypse example, there are Breeder Banes. Guess what they do. If a woman gets pregnant from a Breeder Bane, she gives birth to a Ferectoi, a type of fomori that is wholly devoted to the Wyrm. The fetus doesn't necessarily damage the birth mother... at first. But having a baby with a Bane for a soul can inflict the worst case of peripartum depression ever, as the mother starts to suspect that her pregnancy isn't natural and there's something wrong with the kid. And if she should actually act on those urges and try to terminate the pregnancy, when the Ferectoi comes to term, it usually repays those sentiments tenfold, crippling if not killing the mother during birth.
    • The Mage: The Awakening supplement Intruders: Encounters With The Abyss has the Nativity, children born from the Abyss impregnating unfortunate Muggles. They are Paradox magnifiers, living curses of bad luck, cause the mother to become overprotective to the point of paranoia...And have no idea they're causing any of this, leading to major sympathy as everyone blames them for a crime they didn't know they commit. Woobie, Destroyer of Worlds, ahoy!
    • Changeling: The Lost has Fetchspawn, the offspring of a Faerie human-impersonator and a human they've fallen in love with; they're generally born sociopathic monsters who are very likely to disappear into the Hedge one day, but that doesn't mean that's where the trouble starts. The extremely rare occasion that two Changelings actually manage to reproduce may also spawn a child as half-fae as their parents, whose Fae nature can be detectable (or even obvious) before its birth.
    • Mage: The Ascension had the Widderslaint in the Book of Madness, reincarnated Nephandi (mages who are evil because of their warped souls— or possibly whose souls are warped because they're evil). The fluff text describes a Widderslaint infant who crawled into his twin brother's crib and strangled him to death.
  • This is how Genestealers from Warhammer 40,000 differ from Facehuggers, Headcrabs and most other providers of the Face Full of Alien Wing-Wong - they corrupt the DNA of the victims so that the offspring are horribly mutated, but hypnotise the parents (or this happens as part of the infection) into looking after it. From the parents' point of view, they aren't this at all.
  • "Blood Babies" from Deadlands Classic are "Abominations" from the southern parts of America that superficially resemble newborn human children and have a penchant for clawing their way out from inside a woman's uterus. And this, friend, is why you should always boil water before you drink it.
  • F.A.T.A.L. has a particularly depraved version in which people can be made pregnant by a rapist sword and give birth to another sword. And this, friends, is one of many, many reasons why you Should Not Play FATAL.

    Video Games 
  • In Silent Hill 3, it turns out that Heather is "pregnant"note  with a freakish God (or devil, whichever you like). Made more terrible when she vomits up quivering God-fetus. Made more more terrible when Claudia eats it.
  • The demon's final form in Slashout is a scary-looking green demonic foetus with horns and red eyes, in an incubation chamber located in the heart of it's lair.
  • South Park: The Stick of Truth: After the abortion scene you have to fight off waves of aborted Nazi Zombie fetuses ending in a boss battle against the huge mutant undead fetus from Khloe Kardashian's latest abortion. It's one of the most disturbing parts of the game, especially if sympathise with the dead babies.
  • The first Parasite Eve becomes a race to stop this in the game's latter half. In a strange twist, the pregnant "woman" in question is doing this deliberately.
  • Shin Megami Tensei III: Nocturne has as one of the three last major enemies Noah, god of solitude. Isamu as the core, curled up in a fetal position surrounded by a red orb Equal parts this trope, Body Horror and pure terror.
  • In the massive Dragon Quest I romhack Dragoon X Omega, the Big Bad is revealed to be a goddess, corrupted by her unborn child. After the first round, it tears from her womb to continue the fight.
  • In Haunting Ground, Riccardo needs Fiona's womb/azoth so she can give birth to him (possibly repeatedly) as a means of living forever.
  • Fetus of god in Vampire Savior, where Jedah tries to drain the energies of captured ''Darkstalkers to bring forth The Antichrist.
  • At the end of FEAR 2, Alma "rapes" Beckett and gets pregnant. Alma then puts Beckett's hand to her stomach and a little voice, which is not Alma's, says "daddy".
  • At the end of Overlord: Raising Hell, it is shown that the Overlord's mistress is pregnant. Said hellspawn is the protagonist of Overlord II.
  • In Final Fantasy VII, Lucrecia Crescent allowed her unborn child to be injected with Jenova cells. The direct result of this experiment was the main antagonist Sephiroth. During her pregnancy, Lucrecia got horrible pain attacks and visions of what her son would become. Granted, it was actually the Jenova cells causing the illness and visions, not the fetus itself, but still.
  • The Nihilanth from Half-Life resembles a giant fetus (with a third arm growing out of it's chest and a head that opens up).
  • Meat Boy: Dr. Fetus is probably the most actively evil fetus ever, and he does it all in his mechanical, tuxedo and monocle wearing preservative jar. Can possibly be an Enfant Terrible since he's out of the womb, but he's also still a fetus.
  • Dragon Age: Origins features a Fetus Terrible as an important plot point in the climax. It's revealed that an archdemon is killed, the Old God that inhabits it will simply jump into the next tainted creature nearby. The only thing to prevent this is to have a Grey Warden deal the killing blow as they gain their powers from the taint but still have their own souls, so the soul of the Warden and the Old God will annihilate each other. Your companion Morrigan offers to perform a ritual that enables her to become pregnant with the child of a Grey Warden. When a Grey Warden deals the killing blow to the archdemon, the Old Gods spirit will jump into the tainted child instead and save the Warden from having to sacrifice themselves. Morrigans only condition for going through with it is that she is to leave after the battle and raise the child on her own. In Dragon Age: Inquisition, the Inquisitor encounters Morrigan and her now ten-year old son Kieran, a normal looking but creepy and suspiciously knowledgeable child. The Old God's soul is eventually extracted from Kieran, rendering him a human child and ultimately subverting the original implication that he was going to become an Old God in human form.
  • In Dead Space, there are the Lurkers. Originally, they were clone-fetuses being grown in People Jars as spare body parts for the miners aboard the Ishimura, but became necromorphs. They crawl up the walls and shoot slime at you from their Combat Tentacles.
  • In Batman: Arkham City, if you search Joker and Harley's HQ, you can find a positive pregnancy test laying around indicating that Harley is pregnant with The Joker's child. The fact that the child was conceived while The Joker was suffering the side-effects of Titan can lead to some pretty terrifying implications. However, it's revealed in Harley Quinn's Revenge that Harley merely got a false positive on her test after a long string of negatives.
  • In The Binding of Isaac:
    • Killing Mom's Heart 10 times will replace it with a boss called It Lives!. It Lives! is a giant fetus that's seemingly attached to Mom's Heart as a result of pregnancy Gone Horribly Wrong. The battle is no different from Mom's Heart aside from the fact that It Lives! summons bosses like Chub and Teratoma during the battle.
    • Dr. Fetus makes a cameo appearance as an unlockable item - the Fetus In A Jar, which replaces your tears with bombs. There's also the Epic Fetus item, which drops absurdly powerful missiles onto your enemies. The unlock image even has the Epic Fetus Flipping the Bird at you as missiles rain from the sky!
    • Afterbirth introduces the item "Cambion Conception", which makes your character visibly pregnant. After being hit enough times (described in-game as "feed them with hate"), it spawns a random demonic familiar to follow you from then on. The character Lilith starts with this item.
    • Repentance introduces Tainted Lilith, whose only method of attach is to release her demonic fetus, named Gello, out of her womb, wherein it becomes controllable and fires tears at enemies. Beating Delirium with this character unlocks a Gello item that gives other characters the same ability, albeit once every two rooms.
    • Repentance also has Vis Fatty enemies, which have a demonic fetus - called Fetal Demons - attached to an umbrical cord that chase after the player, though are limited in range due to being tethered. Killing the Vis Fatty first will allow the Fetal Demon to fly around the room and chase after the player freely.
  • In Cry of Fear, one kind of enemy is a pale-skinned pregnant woman whose unborn child bursts out of her womb to attack you with knives. It can also mind control you into killing yourself unless you resist the influence.
  • Medivh from the Warcraft series. He was possessed by the spirit of Sargeras (Warcraft's equivalent of Satan) while he was still in his mother's womb. He got better by the time of the third installment. It latter turns out that Azeroth itself is in danger of becoming this should the Old Gods manage to corrupt the nascent Titan world-soul slumbering within its core.
  • The third Darkstalkers game has one, the Shintai, as a plot element - one of the titular Darkstalkers, Jedah, is hoping to use it to rewrite reality. It's shown in the background of the "Fetus of God" stage, and its disgusting, skinless look has been known to unsettle players.
  • In Ōkami, the source-of-all-evil Yami appears to be some kind of giant, modular mechanical orb, but when you finally manage to cut through his layers of defense, his core is a clear bubble with a small fetus-like creature inside. This may be a metaphor for the evils of technology.
  • The ORN Emperor from Thunder Force VI is an extremely ugly and monstrous infant with 3 eyes and varying number of irises in each of them. Apparently, the design was lifted from a character from a manga the project director had once drawn.
  • Neo Contra has Gegebonne the Saprophagous Head and Shadow Beast Kimkoh.
  • Played very tragically in The Witcher 3: Wild Hunt. Botchlings are monsters born from the tortured souls of stillborn babies who were hastily discarded and buried without proper ceremony. They look like deformed toddler-sized fetuses, caked in dried blood, their umbilical cord wrapped around them like a strangling vine, and their enormous mouths filled with many sharp teeth. While they normally only prey on pregnant women, they can transform into a larger and more powerful form if directly threatened, a form akin to an alghoul. It is also possible to appease one into becoming a gentle guardian spirit for the family household, but this requires one of the parents to undergo a ritual which is both physically dangerous and emotionally traumatising.
  • In DmC: Devil May Cry, Dante barges into a night club owned by a demonic mistress of Mundus, who is heavily pregnant with their child. At the beginning of the boss battle, the child sprouts out of the mother's body, sucking her insides itself and transforming into a huge demon baby. After defeating it, its forced back into the womb.
  • Darius II has the Bio Strong, a giant embryo, as the final boss of Zone V and Zone Z. It has a pitiful moveset consisting of only two different attacks, but that's not to say they're easy to dodge... The updated version, Super Darius II, meanwhile has Mech. Bio Strong, which is best described as a Cyborg fetus. This one has more moves than its organic counterpart, though one can find a safe spot if they park their ship so that it lines up with the chest of the boss.
  • Lore entries in The Secret World reveal that Uta Bloody Valentine AKA the White Rabbit started out as an example of embryonic cannibalism, for though she was ostensibly an ordinary human embryo, she assimilated her twin sisters in the womb - and the birth was so difficult that it ended up killing her mother too. As a result of this, she was born with the souls of her dead siblings rattling around inside her head and an unprecedented prowess in magic. For good measure, lore for her mentor Lilith actually features references to the real-world phenomena of embryonic cannibalism among sharks.
  • Dragon Quest: In Dragon Quest III, the Orb of Light is given to Erdrick by the Dragon Queen, moments before she dies in birthing the egg of her heir. Return later, and the egg is gone— and an NPC will comment on how something flew down into the Pit of Gaia, the only passage between the Upper World and Alefgard, while it was still open. Coupled with greater hints in the Emblem of Roto manga, all signs point that her child ultimately became the Dragonlord who conquered Alefgard in Dragon Quest I.
  • The Big Bad of Kirby and the Forgotten Land is Fecto Forgo, an evil and destructive psychic alien whose brainwaves have put the Beast Pack under its control. While not technically a fetus, its appearance while shut up in the Eternal Capsule looks like an enormous embryo.
  • Covetous seems to have this going on, but in a case of Fetus in Fetu rather than actual pregnancy. The game involves a parisitic twin consuming its attached brother's cells / organs and eventually rips out of the brother's chest. (Warning: the game features some incredibly strong flashing lights and can give headaches or seizures as a result, so research with caution.)

When his was in the womb, he ate his own brother, who later turned out to have survived inside his body for his entire life to come out as a baby that is missing an arm and has the head of a full-grown man. It's also an exaggeration of what occasionally happens in the womb.
