* ''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.

* At the end of the ''Webcomic/{{Housepets}}'' storyline "I Was a Teenage Squirrel", Marion's mother reacts to his ForcedTransformation by saying she's lost her son. When Marion protests that she hasn't, she says "I didn't give birth to a ''squirrel''". Marion replies that she didn't give birth to a seventeen year old either, but she accepted him changing into that, and she snaps "Don't talk back to your mother." Despite this ImmediateSelfContradiction, later strips imply she still hasn't accepted it, and they've basically lost contact.

* ''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.

* {{Subverted|Trope}} in ''Webcomic/YellowBrickRamble''. Like in ''Literature/TheMarvelousLandOfOz'', Tip dislikes being addressed by Jack as "Father", but this is on account of [[AdaptationalGenderIdentity being uncomfortable with masculine gendered terms]]; being called "Mom" is perfectly fine and Tip accepts Jack as his child once it's suggested.

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 [[WebVideo/BackstrokeOfTheWest DOES NOT WANT]].

* 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.]]]]

* ''Manga/SoulHunter'': This is the reason for [[ArtificialHuman Nataku]]'s conflict with his father Li Sei. His mother had a miscariage, but a senin came to her and told her that she could have a child if she implanted a certain paopei (the series' [[{{Magitek}} magical artifacts]]) in her womb, which she accepted. When she gave birth, what came out was a [[BodyHorror ball of flesh]] from which Nataku emerged equipped with several paopeis. He rapidly grew into a [[PersonOfMassDestruction freakishly strong]] and emotionless boy. While In Shi still raised him and loved him as her son, Li Sei didn't see him as his child and was even frightened of him. As a result, Nataku loves his mother back, but hates his father.

* 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".
