Usually, motherhood is seen as something nurturing and life-giving. It's something to look forward to. Babies Make Everything Better, after all. Except in this case. This in when things get bad, creepy, or downright terrifying. Like its counterparts Eye Scream and Body Horror, this trope is dependent on the Primal Fear of things going wrong with a pregnancy, taken to disturbing levels.
It's painful, traumatic, bloody, and potentially life-threatening. Babies may turn into grotesque monsters, which is common in works about fearing parenthood. This trope often carries supernatural elements, with women carrying literal devil-spawn or a Half-Human Hybrid, as somewhat of the evil version of a Mystical Pregnancy.— most often, this supernatural baby is a Child by Rape. Rape scenarios are common even without the supernatural, however. Another theme that may occur is abortion or miscarriage. The imagery may also be entirely metaphorical, with references to wombs and pregnancy rather than anything explicit.
Can overlap with Face Full of Alien Wing-Wong, Womb Level, Spawn Broodling, Chest Burster, and Breeding Slave. Fetus Terrible is a specific example of this. See also Bizarre Baby Boom and Medical Rape and Impregnate.
- Guts and Casca's unborn child is corrupted in the womb when Griffith, a Demon of Human Origin, brutally rapes Casca. After she miscarries the demonic fetus, it suddenly teleports away.
- Trolls are seen to reproduce by raping human women, who are eaten alive by the fetus. Like other Qliphoth inhabitants, Trolls are formed in part from the darkest elements of humanity's collective subconscious.
- The Kushan Empire uses demonic soldiers called Daka as shock troops. These are obtained by plunging pregnant women into vats of demonic essence, corrupting the fetus so it quickly grows and eats its way out of the mother's womb.
- Goblin Slayer: Goblins reproduce by capturing the young women who enter their lairs and using them as Breeding Slaves for the rest of their lives, assuming they don't die from the treatment before that.
- The Xenomorphs from the Alien franchise are meant to invoke this in conjunction with rape horror, in particular their life cycle consisting of involuntary fertilization from a facehugger leading to a Chest Burster. This intent was confirmed by screenwriter Dan O' Bannon in the Alien Saga documentary.
- BrainDead: In the climax, Lionel's zombie mother assumes a One-Winged Angel form and drags Lionel back into her womb, forcing him to fight his way out.
- The Director's Cut of The Butterfly Effect has a scene towards the end where Evan strangles himself as a fetus in the womb of his mother so he would never be born to cause harm to the ones he loved. It's rather played for drama than horror though. Watch the scene here.
- INSIDE is an extremely gory French horror film about a pregnant woman being stalked by an insane woman who wants to cut up her stomach and take her child. The insane woman succeeds at the end.
- Prometheus: Shaw gets a helping of this after sleeping with her black oil-infected husband, culminating in her desperately trying to override an automated surgical unit to abort the fast-growing alien Fetus Terrible before it can tear its way out of her.
- Rosemary's Baby, in which Rosemary's pregnancy becomes a nightmare as she fears she is carrying the spawn of Satan.
- Species II: The male astronaut infected with alien DNA impregnates human women with hybrid fetuses... which gestate and are born in just two minutes. The end result is rather like a Chest Burster, though lower on the torso and coupled with belly inflation.
- Twilight: Breaking Dawn -- Part 1: Human Bella gets impregnated by vampire Edward, and the Dhampir fetus starts slowly killing her. After she dies from the pregnancy and/or emergency non-medical C-section, Edward gives her an Emergency Transformation into a vampire to save her life.
- The titular Brood from The Brood are a group of monstrous Humanoid Abominations that are born from a psychoplasmically-induced external womb growing from Nola. These creatures are connected to Nola on an empathetic level, acting out her desires in the form of murdering people that enrage her and kidnapping her daughter Candice when her father tries taking full custody of her.
- One of The Malloreon's darker moments has the protagonists find a demonic cult waiting for a grotesquely, impossibly pregnant woman to deliver. Whatever Team Mom Polgara the Sorceress does with them isn't described, but is strongly implied to involve Mercy Killing the mother and driving an unborn Demon Lord back to Hell.
- In Graham Masterton's The Manitou, the Indian medicine-man Misquamacus chooses to re-enter the world as a monstrous foetus attached to an external womb on the back of a human host.
- A Song of Ice and Fire: In A Game of Thrones, Daenerys has a run-in with some Blood Magic, which causes her to give birth to a stillborn deformed winged reptilian fetus.
- N. K. Jemisin's Inheritance Trilogy: Implied with Yeine's mother, who famously crossed her legs in an attempt not to give birth and who later had to be prevented from killing her. It's revealed to be because she acquiesced to a Leonine Contract with the gods to make Yeine a vessel for the dead goddess Enefa's soul, and later had a My God, What Have I Done? moment.
- Roulette in Wild Cards apparently had this happen to her. She was infected with the Wild Card virus while pregnant. She became an Ace with the power to produce toxin vagina secretions, making sex with her quite risky (hence the name). Her still developing fetus, on the other hand, well, let's just say that the reason she became an assassin for the Big Bad of her story arc was because he was a telepath who promised to remove the memories of what she gave birth to.
- Fringe: The second episode opens with a hook-up ending in a pregnancy that is well along before the woman can get a few steps away from the motel. She doesn't survive, even after being brought to the hospital.
- The X-Files, "Home": Mrs Peacock gives birth to a horrifically disfigured and deformed baby that is later buried alive by the Peacock brothers. Agents Mulder and Scully are both extremely uneasy during the autopsy. The baby's face is distorted and its legs are bent out of shape.
Scully: Imagine all a woman's hopes and dreams for her child and then nature turns so cruel. What must a mother go through?
Mulder: Apparently not much in this case if she just threw it out with the trash.
- Barbara Eden is pregnant with what turns out to be an invasive alien baby in the 1974 made-for-TV movie "The Stranger Within." The first signs that something is amiss.... 1.) Her husband had a vasectomy three years ago, and she has not been unfaithful. 2.) The fetus is fully developed and birth is imminent, even though she is only five months along, and 3.) X-rays show that the baby has two hearts.
- In the Masters of Horror episode "Pro-Life", a sheltered, heavily pregnant teenage girl runs away from her deeply religious relatives to request an abortion at a local clinic. An armed stand-off ensues when her father and brothers show up to take her back so she can deliver her child. Then at the end it's revealed that she was literally impregnated by a demon, who shows up purely to collect his demon spawn.
- The Chilean Hip-Hop group Tiro de Gracia has a crude song called "Viaje sin Rumbo"note about a guy who's a Addled Addict and has a couple who always has sex. Then he got sick and was diagnosed with AIDS, he told it to his girl and she didn't care, then they had sex and got pregnant (and infected). The last part is about she goes in the middle of her pregnancy and wanted to do an abortion, dying with the baby. Of all the song, this final lines are the creepiest of all:
"Muere en las manos de un falso doctor, el olor a la putrefaccion de los tres es nuestra leccion"note
- Warhammer 40,000: Daemonculaba was an attempt at mass-producing Chaos Space Marines, involving taking female Breeding Slaves and mutating them so their wombs could accommodate an adolescent human and his growing into a seven-foot tall Astartes, who was reborn without skin. If the newborn was deemed acceptable, skin from other slaves was grafted onto him, if not, he was rejected into the sewers, where some survived as the Unfleshed (who somehow resisted falling into Chaos and instead still venerate the God-Emperor).
- The Binding of Isaac has tons of this stuff - it is, after all, a game about a small child and his apparently psychotic mother.
- Among the enemies you'll meet in her basement are creepy blood-stained floating fetuses that emit a shrill scream when they see you and can even teleport behind your back. All the more disturbing that they, as well as many, many others, are supposed to be Isaac's mutilated brothers and sisters.
- And once you beat the game for the first time, you get access to The Womb, which is literally a whole level in Isaac's mother's insides. Almost anything you'll see there falls under this trope, but the most prominent part is the deformed-looking naked humanoids tethered to the walls by their umbilical cords, constantly trying to break free. It's best you don't let them succeed.
- And, of course, there's the final boss of The Womb. A giant heart that summons enemies is more or less normal by the standards of this game, but after some playthroughs it grows vestigial limbs and a head, turning into some kind of baby/organ hybrid.
- One of the nightmares Vincent faces in Catherine is a giant amalgamated horror in the shape of a baby known as "The Child". It's covered in Volcanic Veins as if still developing in the womb, and chases after Vincent, wanting to play with his "daddy". It represents Vincent's fear of losing his freedom as a bachelor and having to settle down when learning that Katherine might be pregnant. He later experiences another nightmare in the form of "The Child With A Chainsaw", where the baby transforms and reveals grotesque rusted robot parts, including a sharp pinching claw for a left hand and a chainsaw for a right. It represents Vincent's fear that the child might not even be his, which means that Katherine is cheating on him just as much as he might be cheating on her.
- Dante's Inferno begins with Dante being sent to Purgatory before making his way deeper into Hell. Purgatory contains enemies in the form of demonic unbaptized babies who spawn out of fiery furnaces shaped like a woman's enlarged birth canal.
- The broodmothers in Dragon Age: Origins fit this trope to a T. Being forcibly impregnated by grotesque monsters, eventually giving birth to legions of them? Check. Bloating up to a deformed, grotesque monster in the process? Check. Being associated with motherhood due to their name? Check.
- The playable teaser of the now cancelled Silent Hills involved some pregnancy-based horror such as the talking fetus in the bathroom.
- In Sonic Dreams Collection, the second-to-last stage of Sonic Movie Maker is initially set in what looks like some giant creature's stomach, until you fall down in a hole and come out... revealing it was Rouge the Bat's uterus.
- In Drakengard, during ending D, The Watchers descend upon the world after Manah is killed. They look like giant babies with fully formed teeth. They are led by the Queen Beast, who resembles a giant woman. Near the end of this ending, she appears to become pregnant and her womb swells to an unnaturally large size.
- Drowtales: It turns out that a type of faulty demonic seed that's been distributed to members of the Sharen clan causes this. Effects range from the mother miscarrying early in the pregnancy, to giving birth to a horribly deformed baby, or at worst the baby ripping out her stomach and leading her possessed body around.
- The SCP Foundation's SCP-231-7 is the last survivor of seven pregnant women extracted from an Apocalypse Cult. Her predecessors underwent progressively more catastrophic [DATA EXPUNGED] upon dying or giving birth, such that the Foundation projects that #7 could kick off the Apocalypse. Whatever procedure they use to keep her from delivering, even members of an organization Conditioned to Accept Horror routinely volunteer to have their memories wiped of the experience.
- One of the nightmarish scenes at the end of the "Sex Survey Results" video of Lasagna Cat features a scene of a woman giving birth into a toilet. She proclaims in Polish that she gave birth to "A human curse", and that if she asks for grace, she won't get it, only having her soul "swallowed and vomited and swallowed again". Looking into the toilet reveals the baby is wearing Jon Arbuckle's shirt.
