In realistic settings, this could be an orphan taken in by a parent who has recently lost a child (to death, relocation, etc). In a sci-fi setting, the typical trope is the lonely scientist who [[CreatingLife creates]] a [[RidiculouslyHumanRobot robot]], [[ArtificialHuman android]], [[BrainUploading artificial intelligence]], [[CloningBlues clone]], or [[RobotMe robot-clone]] in the image of the deceased (probably first seen in this form in the classic ''{{Metropolis}}''). Often it's a RobotGirl or RoboticSpouse.

If the ReplacementGoldfish is unlucky, they constantly live in the shadow of the dead person and feel they [[WellDoneSonGuy can't measure up]], which can also be the [[WhyCouldntYouBeDifferent secret disappointment]] of the MadScientist.

When a lonely EvilutionaryBiologist fills the void by cloning ''himself,'' he is a TrulySingleParent.

Not to be confused with the DeadPetSketch, not with DoppelgangerReplacementLoveInterest.

[[folder: Anime ]]

* Nuku Nuku from ''AllPurposeCulturalCatGirlNukuNuku'' is not quite a ReplacementGoldfish, in that the scientist takes the brain of the cat he struck in an accident and resurrects it in the body of a hyper-powered, incredibly cute [[{{RobotGirl}} cybernetic]] [[{{Catgirl}} cat-brained girl]].
* Astro Boy in ''AstroBoy'', a replacement for the son Doctor Tenma lost, who died in a car accident playing with a robotic car that Doctor Tenma gave him to make up for the fact that he was so obsessed with developing a super-robot, that he forgot to pay attention to his son. In one version, he was about to apologize for neglecting his son when he got the news.
**Now the incredible super-powers? If you're going to make a robot son, you want it to be the best robot ever! And not get hit by a car. And have machine guns in its ass. And he already had the plans mostly finished...
***Well, ''this time'' his son is not going to be run over by anything short of an imperial battlecruiser.
** Though, for some reason, in the original, the Doctor gets freaked out that his son, a '''robot''', doesn't grow up. In other words, he got surprised that his [[NoWaterProofingInTheFuture robotic goldfish couldn't swim.]]
** Of course, even though Tenma gets freaked out, he still helps Astro off and on and off again (see one example in the "World's Strongest Robot" story-arc and its remake, Urasawa Naoki's ''{{Pluto}}''). And then in the 2003 version, Tenma becomes the stalker dad.
* Pictured above: Honey Kisaragi in ''CuteyHoney'', a robotic replica [=/=] partial clone of the daughter that Dr. Kisaragi lost. She was specifically told by her father that she was her own person, though.
* In the first ''FullMetalAlchemist'' series, Majihal creates simulacra of his lost love interest from years ago. Turns out she was alive, but he had become so obsessed with perfecting his ideal android that he refused to accept an average-looking middle-aged woman as the genuine article. Alchemist Sho Tucker also is obsessed with using human transmutation to recreate his lost daughter, whom he "killed" by using as ingredients in a transmutation experiment, which then died. (In addition, this is pretty much ''the'' reason anyone creates homunculi; the ones made for reasons other than replacing dead loved ones are exceptions.) There are also two ReplacementGoldfish relationships that complement and parallel each other. The orphaned Elric brothers take on their alchemy teacher Izumi as a mother figure, while Izumi herself had a stillborn child and now accepts the Elrics as surrogate children.
** Considering the result is pretty consistently a [[VGCats pus-oozing, organ pile, sin against God]], you'd think people'd learn eventually.
* Rei Ayanami from ''NeonGenesisEvangelion'' is party cloned from DNA from Gendo Ikari's wife, Yui, and is therefore Gendo's replacement goldfish for Yui. She have also died and been resurrected twice, which would make her a replacement goldfish for ''herself'', and she is the surrogate host for the soul of Lilith because she has no soul of her own. Furthermore, Ritsuko considers herself to be a substitute of sorts for Rei. The Dummy Plugs, which are intended to replace pilots, are based on Rei's personality. And don't even get started on the whole thing with Kaji, Misato, and Misato's father, because the implications will require {{Brain Bleach}}.
** Rei could also be considered Gendo's replacement for Shinji. In one of his angry inner rants, Shinji even says as much. The fact Rei was the name Gendo had planned on giving Shinji, if he had been born as a girl, seems to support this.
* An old man in the anime of ''RozenMaiden'' convinced himself the boyish doll Souseiseki was his child, Kazuki, and went so far as to dress her in boy's clothing.
** More like that he probably chose her because she wore boy's clothing in the first place. She wears the same outfit in flashbacks from long before she met the old man, best seen in Overture.
* Variation: [[spoiler:Fate Testarossa]] from ''MagicalGirlLyricalNanoha'' was a [[spoiler:"short-term" replacement for the villainess' daughter, whom said villainess was attempting to resurrect. Fate's inability to mimic this daughter led to much suffering on her part.]]
* In the ''{{Pokemon}}'' short story "The Birth of Mewtwo", the scientist who was working on Mewtwo was attempting to recreate his daughter. He was successful only in creating a clone that would live for only a year in a tank.
** Pokemon also features Jessie attempting (and of course, failing) to train a Ditto to become a replacement goldfish for an ex-boyfriend.
* In ''TheBigO'' anime, R. Dorothy Wainwright was an android created as a surrogate for the deceased daughter of her creator.
* Likewise Naomi Armitage in ''ArmitageIII''.
* In ''{{Chobits}}'', Minoru's persocom Yuzuki, a replacement for his sister (whom you might recognize as [[spoiler:Kaede]] from ''KidouTenshiAngelicLayer'').
** It should be noted, though, that he eventually understands what he is doing to Yuzuki and decides to stop updating his sister's personality into her. Also, the whole thing might be insane if it came from a scientist with no interest for ethics, but it's understandable since he's a lonely 12-year-old who needs some kind of emotional protector.
* Inverted in ''{{AIR}}''. [[spoiler:Minagi's mother has been traumatized by her miscarriage and thinks that Minagi is the dead baby and there was no older child, leaving Minagi to live as "Michiru" at home. Minagi's relationship with her mother deteriorates along with her mother's mental state, and she starts blaming herself for the baby's fate.]]
* Nataku in ''{{X1999}}'' is the botched, emotionless, genderless [[CloningBlues clone]] of the resident {{mad scientist}}'s dead daughter.
* In ''ToukaGettan'', [[spoiler:Yomiko considers Touka to be her dead daughter]].
* Eris did this with her dead love [[TheSlayers Rezo]], giving us Copy Rezo.
* Suzu in ''Hotori - Tada Saiwai o Koinegau'' is a robot replacement for a couple who has recently lost their son to illness, and struggles with the question of whether he has an identity of his own. The "doctor" who's overseeing the process of implanting the dead boy's memories into Suzu also has a terminally ill daughter, but (perhaps wisely) decides against getting a Replacement Goldfish because he's got enough experience with the robot doubles to know that however good the replacement is, it will never really be ''her''.
* There's a trace of this in ''Sonic X'' where Shadow the Hedgehog, despite his current outright abhorrence of humans, chooses to save Chris Thorndyke from an exploding island after envisioning him as Maria Robotnik (it's all the eyes, apparently). Somewhat subverted as it does not stop him from bashing the kid about a bit several episodes on.
* Is it still Replacement Goldfish if, in [[KodomonoJikan Kodomo no Jikan]], the female lead (age 9-10) is [[spoiler:being raised up by her guardian (her mother's lover/cousin) to be [[HikaruGenjiPlan a replacement for said dead lover?]]]] Even to the {{Squick}}able point of [[spoiler:leaving hickeys on the back of her neck]]?
** Well, that plus HikaruGenjiPlan.
* Played with in the second season of ''{{Gundam 00}}''. [[spoiler:Neil Dylandy, the original Lockon Stratos, has a twin brother named Lyle, who eventually takes up his brother's place as Lockon in Celestial Being.]] He grew into being his own person by acting like as much of a {{Jerkass}} as he could when he first came to Celestial Being, purposely failing to deliver during battle, and refusing to feel vengeful when everyone expected him to. Only later does he actually put his heart into filling [[spoiler: his dead brother's shoes]], and it was when he was trying to save [[spoiler: Katatron, the group for whom he was acting as a {{double agent}}]]. Later, he says that as a child he had himself sent to boarding school to get away from the comparisons, and he laments the fact that he will never live [[spoiler: Neil]] down.
* An episode of ''The Third'' features the superweapon Gravestone, whose creator made in the image of his dead son and ended up trying not to use it for that reason.
* In ''{{H2O Footprints In The Sand}}'', Hinata is a ReplacementGoldfish for [[spoiler:''her own sister''. Her older sister, the real Hinata, drowned, and the family forced Hotaru to replace her, telling everyone that Hotaru had died instead.]]
* In ''PetShopOfHorrors'', an early chapter of the manga which became the first episode of the anime involves the Count selling a "rabbit" to a pair of distraught parents - a "rabbit" who looks exactly like their dead daughter, Alice. They take her in and treat her exactly the same as their own daughter, [[spoiler:with disastrous results. It turns out that the "rabbit", when fed sweets, "gives birth to" (is eaten from within by) dozens of {{killer rabbit}}s, each of which go forth, kill, eat, and "give birth" to more killer bunnies until the town is overrun.]]
** Quite a few ''PetshopOfHorrors'' chapters deal with D giving a pet as a replacement for a lost child, spouse, or family member. Almost all of them appear human to the owners and (thankfully) they don't all end like Alice the Rabbit did. In one chapter, D is visited by a man whose famous fiancee just died and [[spoiler:gives him a mermaid that looks just like her...a mermaid which enchants and seduces him before devouring him]]. Another chapter has Leon's younger brother Chris bond with a Maya bird [[spoiler:which appears in the form of Chris and Leon's deceased mother, giving both a chance for emotional release before finally dying of old age]]. In fact, it was in that chapter that D comments on how the pets in his shop will deliberately take the form and role of whomever the owners want, including lost loved ones.
* A slight subversion in ''OnePiece'' as [[BadAssGrandpa Garp]] who wanted to train his grandsons to become Marine officers only to have to have them run off to become pirates when he leaves them in the care of a friend. He then takes in two chore boys, Coby and Helmeppo who coincidentally met Luffy, after being impressed by their spirits and has them become his subordinates. He puts them through {{Training from Hell}} and helps them [[TookaLevelinBadAss become stronger]] and seems genuinely fond of them, but clearly distinguishes between them and his grandsons.
* In ''{{Sola}}'', we find out that the protagonist, Yorito, is actually [[spoiler:a replacement made out of paper by Aono to replace the REAL Yorito, who died sometime in the feudal era in a landslide. Using her paper manipulation abilities as a yaka, she basically planted dead!Yorito's personality and memories into origami!Yorito.]] The whole thing is a bit disturbing when you think about it.
* [[spoiler:Shiina]] in ''{{Narutaru}}'' gets to be this in a ''very'' strange way in the manga. [[spoiler:She's a replacement for ''herself'' after she is killed by a fighter jet; it's basically the handiwork of her real {{Mon}}, the Earth itself, because she still has to fulfill her role in what will become of the world]].
** Not to mention that [[spoiler:if you believe the theory that Shiina drowned in the very first chapter, the Shiina we see throughout most of the manga is a replacement of ''that'' Shiina]]. And it's possible that there were other examples even before then. You gotta love ''{{Narutaru}}''.
* In ''[[CaptainHarlock Cosmo Warrior Zero]]'', the new first mate, Marina Oki, looks EXACTLY like Captain Zero's late wife.
** ''{{Galaxy Express 999}}'''s Maetel has a startling resemblance to KidHero Tetsuro's MissingMom. This is not a coincidence...
* The Manwha (and movie) ''MySassyGirl'' is about [[spoiler: a man who meets a seemingly deranged woman who forces him to act like her deceased lover ("No soda, ''coffee!''"). By coincidence, the dead lover is the man's cousin.]]
* Sharem in ''ImmortalRain'' is so into her ReplacementGoldfish son that she has no issues with his...eccentricities or his [[KillEmAll views on humanity]].
* The second season of ''CodeGeass'' has Rolo, who was [[spoiler:inserted into Lelouch's modified memories by Emperor Charles as part of a backup plan should Lelouch ever realize who he truly is.]]
* In ''FruitsBasket'', Yuki sees Tohru as a replacement mother figure.
* A story in ''Mermaid Saga'' has Mana and Yuta meet a woman and her young son [[spoiler:who turn out to both be immortal and been together since World War II. Turns out the boy isn't the woman's biological child. He became immortal first and offered her a chance to eat the mermaid's flesh and be with him. She accepted because her own child died and saw the boy as a replacement.]]
* In the ''FullMetalPanic'' novels, this can be a rather disturbing (and possibly implied) view of the two (male) twins Gauron [[HikaruGenjiPlan took in]]. It's revealed that Gauron had actually wanted to lure and take Sousuke in [[LoveAtFirstSight the first time he saw him]], giving him a "dark smile" (read: rapeface), and later even coming out and saying that his plans for Sousuke had been less than pure (hint: it involves buttrape). Later, Gauron ends up taking in two male twins he tells Sousuke "were quite similar to you." It gets worse: The twins are both Asian (like Sousuke), and they are described using similar terms to Sousuke's physical looks ("slender" build, around the same age, with a similar sort of haircut, and one of the twins even uses the same kind of gun Sousuke normally uses - the same kind of automatic pistol, which was also why Kaname knew how that gun worked better than if he had been using a different kind).
* Happens twice in ''RahXephon''. The two main leads, Ayato and Haruka, inadvertently seek out ReplacementGoldfish for one another after they're separated across time by the arrival of the Mulians. Haruka starts dating [[spoiler:Ayato's twin brother]], and Ayato becomes infatuated with a girl [[spoiler:who's actually a spirit that's adopted the guise of Haruka]]. Eventually, they are reunited and everything is set right with the help of the titular GiantMecha.

[[folder: Comic Books ]]

* ''YTheLastMan'' averts this in the DistantFinale. Yorick refuses to even consider the offer implied by theories concerning 'bringing back' any number of dead women and a sample of [[spoiler: 355's hair]].
** Played rather straight in the same series' penultimate chapter [[spoiler:when Dr. Matsumori is revealed to have used his estranged daughter's tissue samples in the hopes of being a proper father to her this time around. Alison Mann (''neé'' Atsuko Matsumori) is annoyed over it, but she did not like the guy anyway, even before finding out he had sabotaged her own [[TrulySingleParent cloning project]] out of sheer ego]].
* Spygirl, the Japanese knockoff of Spyboy, [[spoiler:is/has an entire assembly line of Replacement Goldfish for herself. The Japanese spies don't understand why the Americans put so much effort into Spyboy if they were only going to make one.]] Her one solo story ends with the current model getting this explained to her via a flashback explaining a picture of her she doesn't remember taking [[spoiler:ending with the Spygirl in the picture dying and being replaced with her. She's then drugged to forget the whole thing and has the photo taken away, with her superior who's been flashbacking remarking that if she figures it out again she can always be replaced.]]
** Painkiller Jane suffers from the same issue.
* A significant problem in SpiderMan and Mary Jane's marriage, is that M.J often had the problem of feeling like she couldn't measure up to Spidey's first love, Gwen Stacey. But hey, it's not like [[OneMoreDay THAT'S a problem any more!]]
** Hell, it was shown in House Of M that his hearts desire is to be married to Gwen and to a father a kid with her.
* Part of the reason Jason Todd went nuts after his resurrection was because he thought {{Batman}} just replaced him without question. The other part was that Jason's killer was still alive.

*The Professor does this twice in TheNightmareBeforeChristmas. The first is Sally, who proves very undesireable, rebellious and disobedient. Exasperated, the Professor gives her her freedom and [[spoiler: makes a female robot who uses half of his own brain.]]
-->"think of the conversations ''we'll'' have, my dear."
** Just the once, actually-Sally was the first goldfish. Presumably before Sally he did his own freakin' housework.
* In ''{{Vertigo}}'', Scottie molds the brunette Judy into the image of the elegant blond Madeleine after the latter woman breaks his heart by committing suicide. Cruelly ironic once learned that [[spoiler: Judy really ''is'' the "Madeleine" he'd known — she impersonated the real Madeleine as part of Elster's plan to cover up his murder of his wife.]]
* In ''A.I.'', the android child David is adopted as a replacement for Henry and Monica's comatose son. The problems really begin when the "real" son wakes up.
** Android David was also created in the image of Professor Hobby's dead son David.
* In ''North'' (best-known for starring a very young Elijah Wood and [[http://rogerebert.suntimes.com/apps/pbcs.dll/article?AID=/19940722/REVIEWS/407220302/1023 Roger Ebert's infamous review of the film]]) one of the title character's several adoptive families almost immediately start trying to shape him into the image of their dead son.
** Extra creepy because this appears to merely be a pleasant bonus to their stated goal of having the biggest of everything in Texas-son included.
* Ripley and Newt in ''Aliens''.
* Violet and the CreepyChild in ''Ultraviolet''.
* In an attempt to replace their stillborn daughter, Kate and John Coleman adopted a mysteriously intelligent nine year old Russian ''Film/{{Orphan}}'' called Esther into their family.... [[ItGotWorse Bad]] [[HighOctaneNightmareFuel Mistake.]]
* The Francis Ford Coppola version of the story of ''{{Dracula}}'' had the title character attracted to Mina because of her resemblance to his lost wife Elizabeta, who killed herself (and in the church's view, damned herself) because of a false report of his death spread by his enemies, which led to Dracula renouncing God and becoming a vampire.

[[folder: Literature ]]

* The classic literary example, pleasantly twisty, would have to be [[http://en.wikipedia.org/wiki/Rebecca_book Rebecca]].
* ''[[LoisMcMasterBujold Ethan of Athos]]'': Terrance brings his wife's corpse to the best scientists money can buy and asks them to revive her. They can't, but offer to create a clone identical to Janine in looks, personality, and mannerisms - perhaps even with a few improvements. Terrance declines, but he does have the scientists splice her DNA into donor ovaries so that he can have thousands or millions of Janine's babies.
** Averted with prejudice in the same series's ''Mirror Dance'', by both Miles' and his mother Cordelia's emphatic refusal to treat Miles's clone Mark as anything but Miles' brother. One of the reasons for this is that in the setting, most civilized societies with cloning technology treat a clone as legally either the child of the person who originally commissioned its creation, or the sibling of the clone's genetic progenitor.
* In ''ForeverAmber'', the heroine Amber marries the creepy, elderly Earl of Radclyffe. It turns out he's attracted to her because of her resemblance to his long-lost love, Judith, and even has Amber wear Judith's wedding gown. Neither Radclyffe nor Amber realize that [[spoiler:Judith was Amber's mother]].
* In ''DoubleIdentity'', [[spoiler:Bethany was cloned from her parents' deceased daughter Elizabeth]].
* ''My Sweet Audrina'' by V.C Andrews has an odd twist to this trope. Audrina, the title character, is a girl living in the constant shadow of her elder sister who had died nine years before she was born, and her parents have absolutely no qualms about letting their daughter know that she was born and raised for the sole purpose of replacing her dead sister. [[spoiler:But as it turns out, Audrina and her sister are one and the same. Audrina had a very sheltered life and, on one of the few times she was allowed to walk home without an escort, she was attacked and raped. She managed to get home safe and sound, but after a few suicide attempts her father forced her into [[LaserGuidedAmnesia electro-convulsive therapy]] in order to erase her memory of the event, and many of her supposed mental problems, as well as the personality defects her parents are constantly trying to fix, are caused by the initial treatment and the constant confusion her parents keep her in to maintain the amnesia]]. And, as it turns out, that's only ''one'' of her problems...
* ''Tarzan'' was the replacement for his [[RaisedByWolves ape mother's]] dead infant.
* In DanAbnett's GauntsGhosts novel ''Only In Death'', after [[spoiler:Caffran]]'s death, [[spoiler:Dalin Criid]] is slotted into [[spoiler:his father's]] place in the Ghosts. He bitterly resents it but is aware that he can do nothing to stop it.
* Elizabeth-Jane Newson/Henchard in ''The Mayor of Casterbridge''.
* {{Harry Potter}} to Sirius Black. Harry's strong physical resemblance to his father James makes him a substitute for his best friend when Sirius escaped prison. This causes some tension between the two in the text when Harry is revealed to be less daring than James and Sirius is unable to handle it appropriately (saying things like "you're not so like your father at all" and "the danger is what would have made it fun for James" (paraphrasing)), and is reflected also in the film version when Sirius actually calls Harry by James' name in the battle scene where he dies. This ReplacementGoldfish situation is also what prevents Sirius from being the father figure that Harry desires, and Harry from being the best friend that Sirius desires, neither are able to fully transition into the Godfather/Godson relationship because of their inability to get past the physical similarities that James and Harry had. Harry can't be the James that Sirius remembers because he never knew him, and Sirius can't be the father that Harry craves because he's trapped by the trauma of his youth.
* [[spoiler: Sansa Stark]] is apparently one of this for [[spoiler: her mother Cat's UnluckyChildhoodFriend, Petyr "Littlefinger" Baelish]] in ASongOfIceAndFire.
* In ''Jessica'', Ruthie seems to have a rather odd version of this. Her ImaginaryFriend, Jessica, is her constant companion, always eager to play whatever game Ruthie devises and willing to take the blame for Ruthie's actions. Ruthie's parents are unamused and do not play along. Shortly before starting kindergarten, they suggest that Jessica should stay home. Ruthie of course takes her along anyway. After spending the majority of the day homesick and unhappy with only Jessica for companionship, Ruthie is approached by a girl volunteering to be her partner. Ruthie, unsure, brightens up considerably when the girl's name happens to be Jessica. Soon they are best friend, illustrations showing them happily doing all the activities that Ruthie and the first Jessica enjoyed.

* Denji Sentai Megaranger has Shibolena who was created as Samejima Shizuka.
* K9 from ''DoctorWho'' was created by Professor Marius to replace the the dog he couldn't take to his new home, Titan.
** Also used with K9 in a later episode; after bidding farewell to Leela and K9, the Doctor immediately takes out a box marked "K9 Mark II".
*** And ''again'' in the new series with K9 Mark IV being given to Sarah Jane Smith immediately after the heroic sacrifice of K9 Mark III.
* In ''DarkAngel'', Max is eventually informed by her former commander and father figure, Donald Lydecker, who has been hunting her and the other escaped X5s for a long time, that her genetic code contains DNA preserved from his dead wife. She is not an exact duplicate, "more like inspired by".
* In ''StarTrekTheNextGeneration'', Dr. Noonien Soong replaced his wife with an android (with her memories), despite the fact that she was going to divorce him. He went to such extreme measures to make her seem human, even the most advanced technological equipment and everyone she ever met [[spoiler:except Data]] couldn't tell the difference.
** Data himself is arguably a replacement for Lore.
*** And in ''Star Trek Nemesis'' [[spoiler: B4 is clearly set up to become one for Data.]]
* ''{{Battlestar Galactica}}'': This is the origin of [[spoiler: the Cylon Centurions. Replace a goldfish (namely your dead daughter),]] set in motion the end of your civilization.
** Oh, and Cavil was made [[spoiler: in the image of Ellen's father.]]
** All the human models seem to be [[spoiler: Ellen and Tigh's replacement children and/or the Final Five's replacement PEOPLE.]]
* In a more realistic version, ''{{Supernatural}}'' had Dean replace his dead mother by looking after both his father and his brother when he shouldn't have had to. [[LoveMartyr And]] [[MartyrWithoutACause we]] [[DrivenToSuicide all]] [[HeroicBSOD know]] [[DeathSeeker how]] [[BreakTheCutie well]] [[TheChewToy that]] [[TheWoobie turned]] [[SadClown out]].
* ''{{Hamish Macbeth}}'': The episode "Wee Jock's Lament" [[spoiler: has the title character's dog, Jock, run over and killed at the beginning of the episode. At the end of the episode, he ends up receiving another dog of the same breed as a reward for solving the crime of the week--and he names it Jock.]]
* ''{{Series/Heroes}}'': As of the most recent season finale, [[spoiler: Sylar has become one for Nathan Petrelli, complete with his [[EasyAmnesia memories being wiped]] and [[FakeMemories replaced with those of Nathan]], his [[ShapeShifting shapeshifting ability]] being used to turn him into a lookalike of Nathan (which, since he doesn't remember that he can shapeshift, leaves him effectively [[ModeLock mode-locked]]), and the [[FakingTheDead burning of a fake Sylar body]] to convince him that Sylar is most definitely [[KilledOffForReal dead for good]]. Of course, that still leaves [[HereWeGoAgain the hunger that made Gabriel Gray into Sylar in the first place...]]]]
* A mad scientist in one episode of ''{{Sliders}}'' was in fact his robotic replica without even knowing it.
* ''{{Fringe}}'', [[spoiler: It looks like Peter Bishop is one, that the Peter of ''this'' reality died as a child and that in his grief Walter, his MadScientist father, built a reality hopping device and dragged an [[AlternateUniverse alt-reality]] Peter into ''this'' world as a replacement.]]
* "Hi. I'm Larry. This is my brother Darryl, and this is my other brother Darryl." On ''Newhart'', you didn't even have to be adopted to be a ReplacementGoldfish.
* In the "Man On The Street" episode of ''{{Dollhouse}}'' a billionaire uses Echo as a replacement for his dead wife but only once a year.
** In a more recent episode another Rich Dude rents Echo as a more long-term replacement for his wife and mother of his child.
* In ''ThatMitchellAndWebbLook'', Dreamy Pastures Insurance offers as a life insurance policy to replace your dead loved one with someone "prettier and kinder", usually in the Russian bride mold.
* The golem in ''TheXFiles'' episode ''Kaddish'' is also a replacement goldfish, [[spoiler: specifically created by the fiancee of an assassinated man to "play" him in a fake wedding]].
* Juliet from ''{{Lost}}'' is made into this twice, both times by Ben. The first time, he tries to use her as a replacement goldfish for Jack's ex-wife Sarah to further his MindScrew on him. Then again before that, for himself as a replacement goldfish for his [=MIA=] childhood sweetheart Annie.

* In the storyline for the ''MagicTheGathering'' set ''Planeshift'', Yawgmoth (the Big Bad) grants Crovax (the Dragon) a Replacement Goldfish for his lost love, Selenia. Later Crovax lures Gerrard (the main protagonist) to the dark side with false promises of a Replacement Goldfish of his own, though Gerrard sees through the ruse in time. It is unclear whether Crovax realizes that his Selenia Mark II is not the genuine article.

[[folder: Video Games ]]

* In the anime and videogame of ''{{Xenosaga}}'' the character of MOMO was an ArtificialHuman reconstruction of her creator's daughter, Sakura.
** He went a little further than that, Momo being the 100th Replacement Goldfish he created in a full scale production line of androids with her face. His wife on the other hand was none too pleased with seeing a hundred copies of her dead daughter running about the galaxy and mentioned as much.
** Something of an unusual example, as MOMO and the others were originally only meant to replace part of Sakura, as she suffered from a disease similar to [[http://en.wikipedia.org/wiki/Locked-In_syndrome Locked In Syndrome]] and MOMO was meant to become a new body for her. It was only after the poor kid bit it that Mizrahi decided to go the whole hog and use MOMO as a full Replacement Goldfish.
*** This becomes a CrowningMomentOfHeartwarming in the third game when Mizrahi tells MOMO that he had long since accepted that he would never get his daughter back, and had truly grown to love his 'second daughter' as a completely separate being.
**** Scores more heartwarming when Juli herself accepts this fact too.
* In ''BaldursGate II'', the BigBad tried to clone his long-lost love. It ended ''badly''.
* Subversion: In ''[[SamAndMaxFreelancePolice Sam and Max: Season 1]]'', Sam and Max actually get a replacement goldfish, and they worry he'll find out.
** In Season Two, the Goldfish dies, and returns from Hell to kill them. They replace him in their office with a stone replica naming it as the prophesied leader of the sea chimpanzees.
* In ''KingdomHearts: Chain of Memories'', the Riku Replica engineered by Vexen realizes he's a copy (but considers himself ''better'' than the real Riku). That is, until Namine modifies his memories so he thinks he ''is'' Riku.
* In the ''Rockman EXE / MegamanBattleNetwork'' series, [[spoiler:Rockman/Megaman was made by Netto/Lan's father FROM his dead son Saito/Hub]]. In later games, this is spoken of casually. This is also the reason Netto/Lan can use his EleventhHourSuperpower.
** The sequel series, ''Ryuusei no Rockman/MegaManStarForce'', [[spoiler:the robot Empty/Hollow is a replacement for the BigBad Orihime/Vega's dead husband. Ironically, she never pays proper attention to him because he isn't an exact copy, but he ends up developing a soul and falling for her.]]
* In the Nintendo DS game ''ProfessorLaytonAndTheCuriousVillage'', [[spoiler:Lady Dahlia is a robot, like everyone else in St. Mystere except for Flora. She was created by Baron Reinhold to be a replacement for his dead wife. However, her existence as a replacement for the dead wife was so traumatic to his daughter that he had the robot's memory wiped and the Lady Dahlia personality created instead.]]
* SilentHill example: [[spoiler:Maria]], who was born from [[spoiler:James' wish to be with his [[DeadLittleSister dead wife Mary]].]]
* According to the enemy notes, and her appearance, in ''{{Mother3}}'', [[spoiler:[[RobotMaid Lil' Miss Marshmallow]] was built by Porky to replace his human maid, Electra from the previous game (''{{Earthbound}}''), who he apparently had a crush on and who he could no longer be with due to TimeTravel problems.]]
* This is the backstory behind the Prismriver Sisters from ''TouhouProject''. A long time ago, a man named Count Prismriver had four daughters, but he tragically died and the sisters were orphaned. Each went their separate ways, but the youngest couldn't bear to part with her sisters, so she created three poltergeists with the appearances and personalities of her sisters.
* This is also the backstory of Seihou's ([[TouhouProject Touhou Project]]'s 'sister' series) main character [[ArtificialHuman Vivit]]; [[spoiler: Erich, the developer of Saboten energy, suffered an accident while trying to manipulate or test it; said accident has severely injured him, forcing him to survive as a cyborg, and has taken his daughter's life. Thus, Vivit was created by him as a replacement for his daughter.]]
* In RogueGalaxy, Steve was created as a replacement of sorts for Dr. Pocacchio's son Mark, and apparently has some of Mark's thoughts in his neural network.
* This becomes glaringly obvious when you play the prequel to Final Fantasy 7, Crisis Core, when you realise that all of that cool stuff Cloud did? Zack did it first, and Aeris noticed.
* In KnightsOfTheOldRepublic you have the option to help a woman get back her droid. [[spoiler: As it turns out, he became a replacement husband for her. '''In a lot of ways.''' If you find him, he asks you to end his misery.]] "Wow. She really misses her droid, doesn't she?"
* ''SuperPaperMario'' lets you buy [[spoiler:Tiptron]] in place of [[spoiler:Tippi/Timpani after you lose her to Count Bleck/Blumiere]]. You'll ''want'' to do so more likely than not.
* Mona, the protagonist of AVampyreStory, is the latest in a protracted line of ReplacementGoldfish for the villain, Shrowdy von Keifer. After his mother vanished, he went a little goony (well, moreso than usual-the dialog is peppered with implications that even before the Baroness disappeared, Shrowdy was everything wrong with mama's boys) and started kidnapping young women and keeping them in his castle. It's stated once or twice that Mona's been around the longest of all of them because she bears an uncanny resemblance to the missing Baroness.

* In ''ElGoonishShive'', [[spoiler:Grace's was artificially created, but the project was hijacked into a replacement for a scientist's daughter, who died in a car crash. She considers the original Grace her mother, and calls the scientist her grandfather.]]
** Considering the method of reproduction of the Uryuoms that's actually the relationship she has with them
* [[http://xkcd.com/299/ This xkcd strip]] has one character describe doing this in [[FinalFantasyVII a video game]], and then start to evoke a "troubling" extension of the concept to real life.
* A somewhat strange example in ''GirlGenius'' involves the Sturmvoraus family. After [[spoiler: Anevka Sturmvoraus is exposed to the Geisterdamen's summoning machine by her father]], her brother, Tarvek, builds a life-support chamber connected to a pneumatic clockwork girl, so that she can still communicate with the outside world while being kept alive and protected. [[spoiler: The puppet becomes sentient to the degree that when the organic Anevka actually dies, it goes on believing that it is still being controlled by a living master, instead of being self-aware, and fools everyone but Tarvek as well. Eventually, the Anevka personality of the puppet is deactivated after it turns out to have "inherited" a little too much of the family's betrayal gene, and is replaced by the personality of The Other.]]
* In ''{{Misfile}}'' Ash is Kate's [[ReplacementGoldfish surrogate for her dead sister]]. Kate explicitly saying she needs to find a sister in her in one strip. Naturally [[GenderBender boy turned girl]] Ash finds this turn of events rather disconcerting to say the least.
* Used very literally in the beginning of ''AbeKroenen'' where Kroenen's initial interest in Abe came because Abe reminded him of his dead goldfish Wolfram.
* The episode "[[http://www.alessonislearned.com/index.php?comic=37 Caroline's Doppelganger]]" from ''ALessonIsLearnedButTheDamageIsIrreversible'' uses this trope heartbreakingly.
-->'''Father:''' Darling, you can't spend every day searching for your real self. You'll waste living the pale reflection of her life!

* Danielle in ''DannyPhantom'' was created as an imperfect clone of the main character (not only physically younger and female, but with an unstable body). She was a stepping stone on the way to creating a perfected clone, and when she found out, turned into a {{Tykebomb}}.
* Odd spin: In ''{{Transformers}}: Beast Wars'', Megatron had a habit of making replacement Dinobots.. An organic one was made after he defected to the good guys and the transmetal Dinobot II after [[spoiler: his HeroicSacrifice.]] Megatron seemed pleased with these clones (Dinobot II was basically his second in command), except when they followed their template's footsteps a little ''too'' closely.
* In ''[[DisneyAnimatedCanon Disney's Tarzan]]'', the titular character was adopted by Kala who recently lost her baby to Sabor.
* In ''AvatarTheLastAirbender'', Iroh begins treating Zuko like a son after his own child, Lu Ten, dies in battle. He seems to love Zuko for who he is, however, and doesn't project Lu Ten onto him.
**This trope is evoked with Zuko and Katara's relationship when they reconcile, with Katara basically being a sane version of Zuko's little sister Azula. But like the above example, Zuko doesn't project Azula into Katara;she simply fills the emotional void left due to his biological younger sibling being [[AxCrazy unable to have a loving, healthy relationship with him.]] The writers [[TheyWastedAPerfectlyGoodPlot didn't heavily go into this aspect of the friendship]](perhaps due to lack of time), but it is there, much to the annoyance of the rabid Canon!Zutarians.
***It gets weirder when you consider that [[spoiler:due to Zuko being a descendent of Avatar Roku, in a cosmic sense, Katara's technically his ''great grandma''.]]
*In TheVentureBros [[spoiler: the accident-prone [[CloudCuckoolander titular brothers]] have killed themselves numerous times, only to be replaced by [[CloningBlues identical clones]] (with their memories implanted) every time]], a major plot point at the begging of the second season. Sociopath Dr. Venture seems to think this is no big deal.
* When SouthPark killed Kenny [[KilledOffForReal For Real]], the boys tried to make Butters dress in Kenny's coat and even called him Kenny until he stopped cooperating.
* Done by ''TheSimpsons'' in a Halloween Special; Bart, the ''original'' goldfish, wakes from his coma, builds himself a robotic shell, and comes back for revenge. And then there's the time (widower) Flanders offers a bed for the night to an old flame...who wakes up to find Flanders cutting her hair to match Maude's.
* Subverted in Futurama. Yancy names his first son Philip after his long, lost brother (Philip Fry, but called Fry in the series), but not because he wants Philip II to replace Fry, but because he wants Philip to be able to accomplish all the things that his older brother wanted to do, but never did. [[spoiler: Yet...]] [[spoiler: Philip goes on to accomplish all these things.]]

* This has been a major problem with divorced families with teenaged kids still living at home. The mother unconsciously starts treating her son as a replacement husband or the father unconsciously treats his daughter as a replacement wife, sexually and emotionally. The poor kid ends up expected to provide adult advise and adult emotional support to a parent!
* A documentary about the children of Holocaust survivors (''Jews'', BBC Four, June 2008) featured a woman who had survived Auschwitz but whose young daughter had been gassed there. Later she settled in Britain, remarried and had another daughter, who was named after the first one.
** It was once fairly common to name a baby after its deceased sibling. The artist Vincent van Gogh was named after a brother who'd died one year before his own birth.
*** As was Salvador Dalí.
*** This practice was actually used as a plotpoint in [[spoiler:''Beethoven's Last Night'']]
*** Nelson Mandela did this with his daughters.
*** PeterSellers' birth name was Richard Henry, but his parents nicknamed him Peter, the name of their short-lived first child. Eventually he adopted that name as his own. This has not passed without ironic comment, given his later claims that he could only be his characters and never himself.
** It was even once fairly common (and might still be...) to name a child after ''what the parents would've called a stillborn or aborted baby had it lived''. Have fun in therapy, kid!
*** Someone explain why this is bad; does the baby having died make the name unlucky or something? It never got used and it's still a perfectly good name. What's wrong?
****Because many, if not most, parents develop attachments to their infant or [[strike: unborn children]] fetus; the idea that a second child is just a replacement for the same affection instead of a wholly separate person is rather creepy.
*** Probably because the parents may have a few lingering issues or something.
*** In fact, current Ashkenazi Jewish custom is to avoid naming children after people who died young, or at least not using it as their primary name, out of fear it would bring bad luck and cause the new child to also die young.
**** 'Course it was common when more than half your kids were definitely going to die before they turned five.
*** Totally subverted in Mongolian culture, where if a couple's children keep on dying young, they would name the newborn something like 'Vicious Dog', 'Not This One', 'No Name', 'Not a Human Being', or give a female name to a boy. This was to make the evil spirits leave them alone, or to confuse the spirits.
*** This actually got rather strange in cultures where there were rules on which relatives you named offspring after -- names were heirlooms, passed down through the generations, and in some you could easily guess exactly what a couple's children would be named ''just from reading the family tree.'' (And yes, some basically did not count babies who were stillborn or died very soon after birth, either.) Talk about maximizing both the potential for ReplacementGoldfish ''and'' confusion!
** In ''Maus'' Art Spiegelman touches on this point, describing some warped sibling rivalry he had with his brother Richieu, who died in the Holocaust before he was born.
*** Specifically because his parents kept a large photograph of Richieu and then of course [[spoiler: Art's own father calls him Richieu at the end of the book.]]
