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 is 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.
This often makes use of Parasitic Horror. Can overlap with Face Full of Alien Wing-Wong, Womb Level, Spawn Broodling, Chest Burster, Abortion Fallout Drama, and Breeding Slave. Fetus Terrible is a specific example of this. See also Bizarre Baby Boom and Medical Rape and Impregnate.

- 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.
- Deadtime Stories: Volume 2: In "On Sabbath Hill", Professor Weaver's pregnant mistress is Driven to Suicide when he callously abandons her. Afterwards, he is haunted by her Vengeful Ghost, who looks like a decaying corpse. Eventually, he sees her rotting body give birth to their monstrous child.

- Pan's Labyrinth: Ofelia's mother Carmen has a complicated pregnancy and suffers a bloody near-miscarriage. This inspires Ofelia to seek the Mandrake root to heal her.

- 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.

Multiple golliwog dolls then burst out of her stomach. As more Gollys are born, Audrey dies.
- The Fly (1986): Because it's likely that Seth impregnates Veronica after his DNA has already been merged with the fly (due to his Slow Transformation having an enhanced libido as a side effect), she understandably worries what effect this could have on the child and tries to have it aborted. During a Nightmare Sequence, she gives birth to a giant maggot. The sad thing? When Seth finds out about her intentions, he's upset because there is a chance that the child was conceived before he had his Teleporter Accident, in which case it would be both fully human and the last remnant of the man he once was. The audience never learns which situation applies due to the film ending right after Veronica mercy kills Seth, leaving it to the 1989 sequel The Fly II to reveal it is indeed an Uneven Hybrid.
- The first half of Good Manners is this. Wealthy woman Ana is pregnant and hires protagonist Clara to take care of the soon-to-be-born child.

Ana gruesomely dies giving birth to a werewolf, thus starting the second act of the movie.
- One of The Malloreon's darker moments has the protagonists find a demonic cult waiting for a grotesquely, impossibly pregnant woman to deliver.

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 that 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.

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.)

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.

- In The Boys (2019), when Homelander talks to Vogelbaum about Rebecca Butcher, who disappeared after being raped by Homelander, Voglebaum mentions that she was rushed to their facility, but the baby used its Heat Vision and Super Strength to claw its way out.

- The Chilean Hip-Hop group Tiro de Gracia has a crude song called "Viaje sin Rumbo"note about a guy who's an 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, the 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).
- Warhammer: The winds of Chaos blowing from the polar vortexes can cause spontaneous in-utero mutations, causing the child born part beast. These children are often exposed, abandoned in the forest for fear they are cursed by the Ruinous Powers. This curse is, unfortunately, all too real and the resulting spawn grow up to be Chaos-enslaved, civilization-hating Beastmen, the first target of whom is usually its parents.
- 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 Limbo before making his way deeper into Hell. Limbo contains enemies in the form of demonic unbaptized babies who spawn out of fiery furnaces shaped like a woman's enlarged birth canal.
- Dragon Age: Origins:
- The broodmothers 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.
- While not as obviously horrific as the above example, this is part of what makes Morrigan's proposed ritual so disturbing; she wants to become pregnant by a male warden (either the player character or Alistair) so that the baby will have the soul of an old god - the Archdemon before it got The Blight. While there are benefits for the player to go along with this (namely, it means that the warden can kill the Archdemon without dying), but the uncertain nature of what this baby could become is presented as a major con.
- 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.

- Mother Chef: The Musical!: After Mother Chef eats all the food, the game suddenly cuts to a black screen, where the player can only hear the sounds of a woman giving birth.
- The theme of the Urashima Woman from Spirit Hunter: NG, a spirit who appears in the form of a pregnant woman. It's revealed that she was killed after childbirth by her midwife and had her baby stolen; she roams the lake searching for her child, and kills those who can't tell her where he is (or those who throw rocks into the lake, as she interprets it as an attack on the dead fetuses that were dumped there). After she's pacified, it's implied that the midwife filled her swollen stomach with rocks to weigh her down when she was thrown into the lake.
- 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.
- Monster Pulse is a Mon series with the twist that the monsters are people's body parts disembodied and mutated into a monster whose abilities derive from that part's function. A member of the clandestine organization responsible for this is paranoid about such a thing happening to her and has a nightmare of her womb turning into a monster.
- 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.
- Anything related to Sarkicism. Case in point, one of its patron saints is said to be constantly inseminated and birthing horrid monsters by the prophet of the religion.
- In Tales from Cherryshrub, Mississippi, a nameless woman is given a potion by a shady man as a remedy for her barrenness. What he doesn't mention is that she would be giving birth to a spawn of an ancient Eldritch Abomination who enlisted her cult with gestating different women so she could rule over the known universe.
- 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.
