->''"I'm telling you that that thing upstairs isn't my daughter. Now I want you to tell me that you know for a fact that there's nothing wrong with my daughter except in her mind. YOU TELL ME YOU KNOW FOR A FACT THAT AN EXORCISM WOULDN'T DO ANY GOOD! YOU TELL ME THAT!"''
-->-- '''Chris [=MacNeil=]''', ''Film/TheExorcist''

A trope common to SpeculativeFiction, in which a victim finds their genes, DNA, soul, or "essence" taken or copied without their permission, resulting in an offspring which is either unnatural or unwanted--or ''both''. This being could be a {{Clon|ingBlues}}e, HalfHumanHybrid, HumanoidAbomination, or a {{Designer Bab|ies}}y created by a StalkerWithATestTube. Sometimes, the villainous party may take what they want from the character's ''real'' offspring instead, twisting it with BodyHorror, DemonicPossession or TheCorruption, prompting the parent to now consider it a different entity entirely and deny any kinship. In any case, the clear message is that the parent [[MemeticMutation DOES NOT WANT]].

Things can get even {{Squick}}ier if the "offspring" is a full-size, adult clone. In RealLife, monozygotic twinning (identical twins) is as close as you can get, so most would consider a copy that's close to their age (or even older) a "sibling" rather than a "child"… although that's moot if this trope is played straight, of course, as the reaction will instead be "That Thing Is Not My Sibling."

This can become the progeny's source of angst or their FreudianExcuse for turning evil. For this trope to be in effect, it has to be clear that the "child" is considered a new creation outside of the "parent's" control (i.e., rape, cloning, or some sort of freak accident). If the parent willfully mated, cloned themselves, or did [[ForScience brutal experiments]] on their own child, only to disown them later, that is a different matter.

This trope is often the result when TheBadGuyWins in a story with a StalkerWithATestTube, or after a character catches a FaceFullOfAlienWingWong. A common reaction is ButICantBePregnant, and sometimes happens in RealLife with a ChildByRape. See HalfBreedDiscrimination for what happens to children that live with this stigma. Sometimes happens in RandomSpeciesOffspring cases.

If the child is lucky, they can find a ParentalSubstitute. If their parents [[AbusiveParent absolutely hate them]], they will ''need'' one.

Do not confuse with IHaveNoSon, in which the parent disowns a disappointing child. See also ClonesArePeopleToo, in which a person doesn't actually consider said clone family, but nonetheless respects their right to live. If a parent maintains that it '''is''' their child, despite bad behavior, it's MamaDidntRaiseNoCriminal.


[[folder:Anime and Manga]]
* This seems to be much how Guts reacts in ''Manga/{{Berserk}}'', after [[spoiler:Casca miscarries and gives birth to a hideously deformed child after the events of the Eclipse where she was raped by Femto]]. Unlike most examples on the list, it actually ''is'' his child, but merely corrupted by events outside of his control.
* In a particularly [[{{Tearjerker}} heartbreaking]] example, ''Manga/FruitsBasket'' features [[StepfordSmiler Momiji's]] mother reacting this way (using the almost exact quote) upon discovering that her child [[InvoluntaryShapeshifting turns into a rabbit when she holds him]] because he's under the zodiac curse. Momiji's father had [[spoiler:her memory of her son erased]] to aid her failing health brought on by the emotional stress of all this.
* A major element of [[spoiler:Historia[=/=]Krista's]] backstory in ''Manga/AttackOnTitan'', being rejected and denied by a mother unable to find the courage to [[OffingTheOffspring kill that "thing"]].
* ''Anime/MagicalGirlLyricalNanoha'' eventually reveals this is how [[spoiler:Precia feels about Fate]] due to her not being a perfect clone [[spoiler:of Alicia, her first daughter]].
** Averted with [[spoiler:Quint Nakajima]] in ''Anime/MagicalGirlLyricalNanohaStrikers'', who took in two combat cyborgs she rescued from an illegal research facility and raised them as her daughters, only to later discover that they had been cloned from her. We never do find out how she felt about having her DNA used for making SuperSoldiers, but she definitely didn't hate her children for it. [[GoodParents Quite the opposite, actually]].
* ''Manga/AngelSanctuary'': Setsuna's mother disowned him because she realized from an early age that something was WRONG about him, that he wasn't really her child. She was right - he was possessed with the soul of a fallen angel since birth. What she doesn't realize is that [[spoiler: HER DAUGHTER ALSO HAS AN ANGEL'S SOUL.]]

[[folder:Collectible Card Games]]
* ''TabletopGame/MagicTheGathering'''s Innistrad set has a card named Cloistered Youth with the ability of transformation.[[note]]It is a double-sided card that can be flipped when certain conditions are met.[[/note]] When transformed, it becomes Unholy Fiend.
-->''"I heard her talking in her sleep, pleading, shrieking, snarling. It was not my daughter's voice. That is not my daughter."''

* Comicbook/{{Cable}}'s reaction to the "son" which was sired when his identical clone Stryfe raped his wife. Ironically, Cable himself is the son of Madelyne Pryor, aka "The Goblin Queen", the [[EvilTwin Evil Clone]] of Jean Grey. She handled it better. Considering her husband/his father abandoned him in Alaska to explore his feelings for her, it's the least she could do.
* Averted with ComicBook/{{Superboy}} in the comics, whom Franchise/{{Superman}} initially accepts as an ally and successor, and then as a cousin. However, he never explicitly sees him as a ''son''. (Although an in-universe newspaper article written after Superboy came BackFromTheDead states that Superman felt Superboy's death was "like losing a son".) Even averted with Comicbook/LexLuthor, who created the boy and donated the other half of the DNA, and considered him more of a son than even Superman did… [[IHaveNoSon at first]].
* Averted with Franchise/{{Batman}} and Damien Wayne, the [[LegacyCharacter fifth Robin]], who may or may not have been the result of a StalkerWithATestTube.
* ''Franchise/SpiderMan''
** Played with between Peter Parker and his clone, Ben Reilly. The two eventually resolve their differences and come to see one-another as brothers... even if half the time they aren't even sure who the original is.
*** Ditto with Kaine, though the resolution took considerably longer since Kaine was, basically, crazy and tried to kill both Peter and Ben a number of times. Eventually he sacrificed himself for Peter in ''Grim Hunt'', before returning during ''Spider-Island'' and reconciling with Peter. The two now see each other as brothers, and while they don't always get on with each other, Kaine does genuinely want to be a man as good as his brother, while usually believing himself to be a monster.
** In ''ComicBook/UltimateSpiderMan'', Peter was even tricked into believing an artificially aged clone of himself was his ''father''. He was ''not'' pleased when he learned the truth... nor was his "dad", who was a ManchurianAgent and didn't know about it himself.
** Comicbook/SpiderGirl averted this with a clone of May Parker who started calling herself April - Peter and Mary Jane decided take her in as a second daughter, though officially they claimed she was an identical cousin.
* The roles are reversed with [[PoliticallyIncorrectVillain Graydon Creed]]; he feels this way about his ''father'', Sabretooth, and frankly, having a guy like him for a father may well be ''why'' he grew up to hate mutants.
* Invoked in ''ComicBook/AvengersAcademy''. [[Comicbook/AntMan Hank Pym]] was [[Comicbook/SecretInvasion replaced by a Skrull]] which copied him "to the genetic level" and, during an affair with Tigra, impregnated her. As such, the child is ''genetically'' Pym's. Later, the real Hank Pym returns, and Tigra insists that he has ''no'' parental claim to the baby. He agrees, but she then asks him to be the child's ''godfather'' instead.
* Defied in a ''WeirdScience'' story. The children on a new colony are systematically taken from their mothers at birth, and the mothers aren't allowed to see them. The women's leader eventually forces the head doctor to admit why this is happening: The children are malformed and mutated, and the medical staff was trying to protect the mothers from the horror and trauma. The women basically storm the nursery, and accept the children with open arms. The leader turns to the head doctor, and with a mix of pity and contempt says to him "Did you truly believe we could not love our [[UglyCute own children]]?"

[[folder: Fan Works:]]
* An {{Inverted}} example of this trope provides a CrowningMomentOfHeartwarming for ''[[FanFic/TriptychContinuum A Mark Of Appeal]]''. After Joyous learns that her parents are infected with the same mark-amplifying sickness she suffers from, and that their amplified mark magic has consumed their minds, we get this:
-->'''Joyous:''' It... wasn't them.
-->'''Celestia:'''Joyous? They're your parents. We tracked them. There aren't any other ponies who qualify--
-->'''Joyous:'''-- it's... not what I meant, Princess. I wasn't talking to them. I haven't... I haven't spoken to them for a long time, have I? I was talking to a disease. A disease which doesn't know me, or care about me, and can barely remember me at all. A sickness in two pony bodies. It was the disease which didn't come home when it promised to. Illness never picked me up from school, or took me there on so many new first days. Something which isn't my parents. Which never was.
-->'''Joyous:''' The disease doesn't love me, because it can't. But... if they're cured... then somewhere under the disease... I still have a mom and dam. I always did. They just can't get out...

* The mother in ''Film/AIArtificialIntelligence'' reacts this way to the robotic "child" her husband brings home. Eventually reversed in that she's the only member of the family that doesn't wants to destroy him.
* This may have been the motive for the Cobblepot family from ''Film/BatmanReturns'' to throw baby Oswald over a bridge in its wicker bassinet.
* In ''Film/{{Inception}}'', [[spoiler:Mal and Cobb both react this way when they're faced with children they believe to be fake, while they may or may not be dreaming. The jury's still out on which interpretation, if either, was correct.]] WordOfGod has a [[http://collider.com/inception-christopher-nolan-explains/61972/ strongly implied conclusion]] and a definite final answer.
* In the BMovie ''Film/ItsAlive'', this is a major plot point for the father of a killer mutant baby.
** The father of conjoined twins from ''Film/BasketCase'' has a similar reaction to Belial, the deformed parasitic twin.
* This is how some parents react to the silver-eyed children in ''Film/VillageOfTheDamned1960'' and [[Film/VillageOfTheDamned1995 its 1995 remake]].
* In ''Film/RosemarysBaby'', the title character [[spoiler:turns out to be not the child of Rosemary's husband but rather that of the Devil. Upon seeing her (off-screen) baby for the first time, Rosemary exclaims, "What have you done to it? What have you done to its eyes?" Ultimately averted, as she decides to take care of it anyway.]]
* {{Inverted|Trope}} in ''Film/ThePhantomOfTheOpera2004''. In the graveyard ("Wishing You Were Somehow Here Again/Angel of Music Reprise/Swordfight"), Raoul says to Christine, "This man--this ''thing''--is not your father!" (The Phantom had been posing as the Angel of Music--the ghost of Christine's late father.)
* Towards the end ''Film/RepoTheGeneticOpera'' when Rotti Largo is dying Amber comes up to him [[spoiler: after her face fell off from too many cosmetic surgeries]] and he says to her and her brothers, "Don't come near me, any of you. You're disgusting, you're not my children. You're nothing."
* In ''Film/{{Pixels}}'', Pac-Man's creator Toru Iwatani reacts this way when his brainchild bites his hand off.
* A downplayed example in ''Film/{{Logan}}'': [[Comicbook/{{X 23}} Laura]] is Logan's daughter, via genetic material salvaged from the Weapon X project, and Logan spends much of the film distancing himself from her. [[spoiler:Upon reaching the other X-23 kids, Logan outright states that he'll be leaving her alone after they cross the border into Canada. He eventually has a [[CharacterDevelopment change of heart]], but not long after he's [[DyingDeclarationOfLove mortally wounded]].]] It's downplayed in that it's not so much because of Laura, as it is Logan's [[ItsNotYouItsMyEnemies jaded attitude]] when it comes to relationships, and he's pushing her away to protect her.


* Played straight in ''Literature/{{Duumvirate}}''. Luke ''agrees'' with this sentiment when [[spoiler:killing his parents]].
* ''Literature/VorkosiganSaga'':
** Averted in ''Literature/BrothersInArms''. Miles discovers that a Komarran terrorist cell has cloned him as part of a Byzantine plot. He immediately declares the clone his brother, informs him of the automatically-determined DeadGuyJunior name Vor tradition gives him (Mark Pierre), and goes out of his way to protect and support Mark. His mother Cordelia does the same when she meets Mark. His father Aral is more skeptical; he feels a sense of responsibility, but also admits that he doesn't love Mark the way he does Miles. Eventually even Aral acknowledges Mark as a son. (Rather heartwearmingly, in fact-- somebody comes complaining to him about 'your son' and he asks "which one" ''completely'' offhandedly.)
** Miles himself was not as lucky: His grandfather disowned him and demanded that Miles not get a DeadGuyJunior name from him after learning that the severely damaged fetus was being artificially brought to term. Thankfully, he later repented and accepted Miles as his grandson.
* In ''Literature/TheMarvelousLandOfOz'', Tip, a boy who's "small and rather delicate in appearance," creates a huge pumpkin-headed scarecrow man named "Jack Pumpkinhead" to frighten a witch, who uses magic to bring it to life. This leads to Tip being very uncomfortable with the creature calling him "Father", although he does consider Jack a good friend. At the end [[spoiler: it turns out that Tip is a girl, Princess Ozma, who's been under a spell since she was younger to protect her identity. After being changed back into Ozma, she's thrilled that Jack Pumpkinhead can no longer refer to her as "father".]]
* ''Film/TheExorcist'': {{Trope Namer|s}}. "Father, you show me Regan's identical twin: same face, same voice, same smell, same everything down to the way she dots her i’s, and still I'd know in a second that it wasn't really her! I'd know it! I'd know it in my gut and I'm telling you I know ''[[DemonicPossession that thing upstairs is not my daughter!]]''"
* ''Literature/TheMetamorphosis'': After Gregor Samsa wakes one morning to find he inexplicably transformed into a giant cockroach in the middle of the night ([[MakesJustAsMuchSenseInContext don't ask]]), his family [[TearJerker slowly stops believing the bug was ever their son to begin with and eventually just leave him to die alone in his room.]]
* In ''Literature/TheDemonsLexicon'' the protagonist's mother spent his whole life hating and fearing him because [[spoiler: her magician husband had a demon possess their unborn child before he developed a soul. She tried to drown him at birth and before her death makes it clear that she believes her real child died before it was born and the one she raised is a demon in its body (which is technically true).]]
* in ''Literature/TheMortalInstruments'', [[spoiler:Jocelyn's husband Valentine injected her with demon blood whilst she was pregnant, causing her to give birth to a demonic child who she was convinced was monstrous and evil. She turns out to be right, since Jonathan grows up to be a sadistic psychopathic murderer]].
* Misquamacous in the ''Literature/TheManitou'' series, ''twice'' attempts to return to the mortal world by hijacking a foetus in the womb, and once as a tumorous growth like a conjoined twin, that gradually sucks all the life out of its host before being "born".
* Happens in Literature/EvaLuna, to [[spoiler: Eva's ParentalSubstitute La Madrina.]] She gives birth to [[spoiler: a deformed stillborn kid, and tosses the tiny corpse to the trash.]] What follows is [[TraumaCongaLine a MASSIVE media circus]] that [[spoiler: [[SanitySlippage drives her further into insanity]].]]
* ''Literature/JourneyToChaos'': Basilard is technically [[spoiler: Zettai's]] biological father because a blood transfusion was the only way to save her from Mr.15's experiment; his Bladi blood replaced her human blood. Despite this, he insists that he is her "legal guardian", not her "father" and refers to her as an abomination because Bladi Conversion is a forbidden art.
* Played with in the ''Literature/RiversOfLondon'' book ''Foxglove Summer'': A woman whose daughter went missing [[spoiler: when she followed a unicorn to Fairyland]] is absolutely adamant that the girl who returned isn't her daughter. It turns out [[spoiler: her daughter ''was'' replaced by a changeling, but that happened eleven years earlier; the magical nightmare now in her house ''is'' her biological daughter. Once this is explained to her, she still says that her ''real'' daughter is the girl she raised for over a decade, wherever she came from.]]


[[folder:Live Action TV]]
* ''Series/DoctorWho'': In "The Doctor's Daughter", the Doctor originally reacts this way to his "daughter", actually an OppositeSexClone. He refers to her as a "biological accident" and goes as far as to reject that they're even the same species because there's more to being a Time Lord/Lady than genetics. Donna gives him an earful about this and urges him to change his mind.[[spoiler: He ultimately does and claims her as his daughter as she dies in his arms.]]
* In an episode of ''Series/StarTrekTheNextGeneration'', Riker kills the still-in-development clone of himself produced by the colony that reproduced by cloning (their initial population was too small to provide adequate genetic diversity). Riker cites some "diminished my uniqueness" excuse, (and the fact this was done without his permission). Later, a transporter-accident clone fares better, being recognized as much as Riker as the one on Enterprise. The two act like brothers.
* ''Series/StargateSG1'': Vala Mal Doran eventually develops this attitude towards Adria, the [[DarkMessiah Orici]] offspring implanted in her by the [[SufficientlyAdvancedAlien Ori]].
-->'''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.
* Played with in ''Series/TinMan'' where the [[TheHighQueen Queen]] tells [[BigBad Azkedellia]] that she is "not my daughter." At the time, you think it's just because of Az's bad behavior. [[spoiler: She's ''really'' addressing the Evil Witch that has possessed Azkedellia]].
* ''In The Flesh'': [[spoiler: Bill Macey kills his son, Rick, unable to accept him as resurrected.]]
* In the ''Series/{{Eureka}}'' episode "Many Happy Returns," [[spoiler: the real]] Susan Perkins [[spoiler: doesn't even want to see her clone's child. By the end of the episode, she does anyway.]]
* In ''Series/PersonOfInterest'', Harold goes back and forth on this with regards to the Machine. He deliberately maintains a distant, businesslike relationship with it - its sentience was something he'd done [[SpringtimeForHitler everything in his power to avoid]] - but to [[TokenEvilTeamMate Root]], he compares the dreams of code he had when he was building it to a mother dreaming of her unborn child's face. Then there's the conversation he has with Arthur about whether the Machine (and ArtificialIntelligence in general) is a wonder, or something comparable to the atomic bomb:
-->'''Arthur:''' Everything slides towards chaos. Your creation... it brings us poor souls a cupful of order. Your child is a dancing star.
-->'''Finch:''' It's not my child, it's a machine!
-->'''Arthur:''' A false dichotomy; it's all electricity. Does it make you laugh? Does it make you weep?
-->'''Finch:''' ...Yes.
-->'''Arthur:''' What's more human?
* ''Series/BattlestarGalactica2003'': Double subverted during the "New Caprica" arc. After the Cylon invasion, Leoben Conoy AKA Number Two has kidnapped Kara "Starbuck" Thrace and keeps her locked up in a secluded apartment to force some sort of twisted StockholmSyndrome relationship on her, and since he has plenty of backup bodies, "killing" him just means he'll be back in a few hours. At one point he brings in a little blonde girl that he claims is a human-cylon hybrid, who was conceived with Kara's ovary (which the Cylons had previously removed from her body) and his own sperm. Starbuck initially refuses to accept the child as her own, but when the kid gets hurt Kara seems to acknowledge the child as her daughter. However, when the humans escape the planet it's revealed that the kid in question was actually taken from her real human mother by Leoben as part of his ploy to get close to Starbuck.
* In Series/StrangerThings, Will Byers, the kid missing at the start of the show, [[spoiler: is found dead in a lake.]] His mother cries out at the morgue that it's not her son on the lab table. This gets Sheriff Hopper to examine the body, [[spoiler: and find out that the body they fished out was a convenient fake.]]
* ''Series/LawAndOrderSpecialVictimsUnit'' has a relatively realistic version. The detectives encounter a young teen who is all but homeless because her mother is suffering from Capgras Syndrome, a mental disorder that causes her to not recognize her daughter ''as'' her daughter. She is able to recognize her daughter's voice and pleads to see her, but upon actually ''seeing'' her, she immediately rejects her as a stranger.

[[folder:Tabletop Games]]
* This was what led Lord Soth of ''Literature/{{Dragonlance}}'' and ''TabletopGame/{{Ravenloft}}'' fame to commit his first supreme act of evil, one of several that would ultimately make him a Darklord in the Land of Mists. He and his wife, Lady Korrine of Gladria, had been trying to produce a son to be his heir, and Korrine had consulted a witch about the problem, who had agreed to help them, but had warned her that the child would be a representation of Soth's soul. Unfortunately, Korrine didn't know about the wicked deeds that her husband had done, including ordering the murders of his half-brother and sister by his seneschal Caradoc, else she would have known what would eventually transpire of the birth and would be of a mind to curse the witch. When she gave birth to the son in question, it had a face similar to that of dragon-kin with two arms on one side and a leg on the other, with the last leg placed at the bottom of the buttocks as if it were a tail. To say that Soth was pissed about this was a massive understatement, and thinking that she had cheated on him with some kind of demon, Soth murdered Korrine and the monstrous child.
* In the original Black Box edition of the ''TabletopGame/{{Ravenloft}}'' setting, one example of how curses could be used in adventure-design had a treacherous nobleman who'd been cursed so his firstborn offspring would be a monster: a miniature spirit naga (evil, human-headed magical serpent) that grew rapidly in the hours after its birth.

* Done in the stage adaptation of ''Theatre/{{Wicked}}''. Elphaba's father undisguisedly loathes her with a passion and dotes on her younger sister Nessa merely because Elphaba is green. The moment she's born he screams [[PunctuatedForEmphasis "TAKE! IT! AWAY!"]] at the nurse before angrily storming off. Although, [[spoiler:he isn't Elphaba's real father anyway.]]
* In ''Batboy: The Musical'', [[spoiler:a woman has [[ChildByRape twins by different rapists]] from the night of a FreakLabAccident with pheromones. She loves one baby, because the father isn't so bad ([[MoralEventHorizon yet]]); the other is a HalfHumanHybrid, prompting her to shout, "Kill it!" But her attitude changes when she meets him again years later.]]
* ''Theatre/ThePhantomOfTheOpera''--Inverted in the graveyard scene, where Raoul tells Christine that "This man--this ''thing''--is not your father!" Played (implicitly) straight later on, when Erik reveals that his face "earned a mother's fear and loathing."

[[folder:Video Games]]
* ''Franchise/MetalGear'': This is Big Boss's initial reaction to the Snake brothers, who are his clones; in fact, the discovery that Zero and Para-Medic had cloned him in the first place was the final straw that led to him [[DefectorFromDecadence leaving the Patriots for good]]. As revealed in the Truth tapes in ''VideoGame/MetalGearSolidVThePhantomPain'', [[spoiler:he adamantly refuses to acknowledge them as his sons, to the point of refusing to see Eli[[note]]A young Liquid Snake[[/note]] in Africa]]. Still, he always respected Solid Snake as a man and a soldier, and personally mentored him.
* Averted in ''VideoGame/ParasiteEve2'', when Aya Brea finds out that an evil cult has cloned her in order to create a new 'Parasite Eve' with the ability to control NMC's... despite having standing orders to destroy the girl, and despite said girl going OneWingedAngel on her, she stubbornly refuses to hurt her, and eventually adopts the young clone as her younger sister.
* Played with in ''VideoGame/TalesOfTheAbyss'', with "replicas" (clones) in general. There is one major incident where it is [[AvertedTrope averted]] in a CrowningMomentOfHeartwarming, but most of the time replicas tend to be rejected...in part due to the fact they show up just after the original died (and their creation tends to be what killed the original).
* Averted with ''VideoGame/DeadSpace2'', where a woman calls lovingly to her [[BodyHorror necromorph]] baby... only to get her entrails splattered against the wall when [[ActionBomb it goes kaboom]].
* This is Kitana's reaction towards her 'sister' Mileena's insistence of 'being a family' in her Story Mode chapter in ''VideoGame/MortalKombat9''. Considering Mileena is an evil clone of Kitana created by Shao Kahn, Kitana is very, very justified in her assertion.
* In ''VideoGame/FinalFantasyVI'', this happens in [[spoiler:Gau's]] backstory. [[spoiler:Gau's mother [[DeathByChildbirth died in childbirth]], and his father snapped, declaring Gau a monster and dumping him on the Veldt. Despite his father's paranoid rantings, Gau is, for the record, a completely ordinary human beyond being [[RaisedByWolves Raised By Monsters]].]]
* One boss in ''VideoGame/{{Catherine}}'' is "The Child" (who later comes back as "Child ''[[ChainsawGood With A Chainsaw]]''"), a giant deformed zombie baby. Vincent's reaction? "What the hell is this? I'm NOT your father!"
* In ''VideoGame/WorldOfWarcraft'', this is Alexstrazsa's response after finding out Deathwing has corrupted a large number of young red dragons (and is using them to attack her and the players):
--> '''Alexstrazsa:''' They are... my clutch no longer. Bring them down.
* In ''VideoGame/{{Skullgirls}}'', this happens in [[spoiler:Painwheel's]] ending. [[spoiler:She manages to break free of the mind control and retain her humanity, but her body is still [[BodyHorror that of a horrific monstrosity]], causing her parents to freak out when they see her and throw her out.]]
* In ''VideoGame/Fallout4'', [[spoiler:the player can optionally react this way towards the [[ArtificialHuman synth]] replica of your son Shaun. Or the original, if his possible sociopathy is too off-putting for you.]]

[[folder:Web Comics]]
* ''Webcomic/DestroyerOfLight'': Persephone has an abortion, and the embryo, once outside, turns into a snake. When they catch the snake, it turns into a grapevine. Her reaction? Calling the thing "mommy's boy" - she ''likes'' plants. She's a goddess, so some weirdness was to be expected. [[spoiler: She eventually gets "it" to Zeus, so that he can ... continue the pregnancy, or whatever, and never acknowledges her child, even after finding out that he was reborn as Dionysus, but that's more because she's MaternallyChallenged.]]
* In ''Webcomic/{{Yosh}}'', when Kate was changed into a CatGirl by the [[MassSuperEmpoweringEvent Weirding]], her mother couldn't admit it was still her and had her thrown out. Her father couldn't handle the guilt and eventually set out to correct this.
* Generally averted in ''Webcomic/TheInexplicableAdventuresOfBob'' Jean has no fewer than ''three'' such accidental "children" -- Molly, Galatea, and Djali -- and she has never disputed her title as their "mother" or that she therefore has obligations to them. Molly is the only one she's actually had the chance to raise as a daughter, however.

[[folder:Western Animation]]
* This is Franchise/{{Superman}}'s reaction to ComicBook/{{Superboy}} in ''WesternAnimation/YoungJustice.'' Though he's at least nicer than most examples of this trope-- he never blamed Superboy or considered him a "thing," but he also clearly didn't want to consider him his child. He's also rationalized this as a way to avoid giving Superboy CloningBlues, claiming that it would be better if Franchise/{{Batman}} or someone took on a mentoring role instead. It also may have been because he was just not ready for fatherhood. After the timeskip he's fine calling Superboy "little brother" and "Kon-El" and treating him very nicely.
* Like the above, this also occurs in the animated film ''WesternAnimation/SupermanDoomsday'', when [[spoiler:the Clone]] Superman states that he is the authority figure to the world and has the primary say on what's good for humanity. Cue Martha Kent stating flat out "That is NOT the boy that I raised". [[spoiler:[[CloningBlues She's right.]]]]
* In ''WesternAnimation/{{Gargoyles}}'', Xanatos created a clone of Goliath, who reacted in disgust, calling him a "thing" and an "abomination". Elisa immediately pointed out that "[[SdrawkcabName Thailog]]" could be considered his son, and Goliath reluctantly agrees they should help free him from Sevarius. Unfortunately, Thailog had already learned a few tricks from his other daddies...\\
…resulting in an {{inver|tedTrope}}sion -- it really only takes Goliath about a few minutes to admit that Thailog is his son, but Thailog refuses to accept Goliath as a ''parent,'' claiming he's too weak for him to admire. He rejects [[TheChessmaster Xanatos]] and [[MadScientist Sevarius]] too, but that's more because his own ambitions oppose theirs (though he's eventually willing to work with Sevarius, who is the least like him of his three "fathers" and therefore the one least in direct competition with him).
* Averted with ''WesternAnimation/DannyPhantom'' when the title hero meets his "cousin" Danielle. He's at first untrusting and suspicious of her until learning what she is and accepts his new cousin.
* Humorous example in ''WesternAnimation/StevenUniverse'''s CrossOver episode with ''WesternAnimation/UncleGrandpa'': Upon seeing Pizza Steve dressed up as Steven after a long, long series of reality warpings by said Grandpa driving her to near madness, Pearl cries out in horror: "THAT'S NOT MY BABY!"
