->''"If I could time-travel, I'd go back to the night my parents conceived me. I would just run into the room and smack my dad on the ass -- Wham! 'I'm your son from the future!!' ''Aahhh-hahahaha!!!"
-->-- '''Creator/DaneCook'''

Surprise! Two of the main characters have just had a child! I bet you ''are'' surprised, since they didn't go through pregnancy or anything, might not even be dating, and the kid is already 14!

It must be the Kid from the Future here to SetRightWhatOnceWentWrong! A child the characters have yet to have has traveled back in time to save their parents for some reason. Great for pairing up characters who have yet to even show any interest in each other since now they must get together BecauseDestinySaysSo. Also a way of working in a DistantFinale into the plot of what has already come along.

If the series involves a LoveTriangle, or, worse yet, an UnwantedHarem, expect all hell to break loose as those involved try to figure out who the child's mother or father is.

This trope is also used in FanFiction (especially {{Fix Fic}}s), often to push together the author's [[OneTruePairing OTP]], pair the MarySue with her chosen love interest, or even as the origin for the [[AuthorAvatar self-insert]] or MarySue.

An ''extreme'' form of PlotRelevantAgeUp. Can develop into a full-blown SpinOffspring.



[[folder:Anime & Manga]]
* Rikka Iroha, Reika Kujo and Ichinose Saki from manga ''Manga/MahounoIroha'' meet their present father, Rikka Naoki. [[spoiler:Two of them meet him probably because his future-self don't spend much time with them. And the another one, meet him for another reason.]]
* Trunks from ''Manga/DragonBall''. In his case, his parents might have had two scenes together at that point and his mother had been with a different guy for about ten years. Goku's reaction is [[FaceFault shock and disbelief]]. Neither of his parents actually know who Future Trunks really is until after they've gotten together, as neither Goku nor Piccolo (who overheard Trunks telling Goku due to his superior hearing) said anything. Eventually, the present-day Trunks is born, and Future Trunks meets him. Hilarity ensues.
* Chibi-Usa (future daughter of Usagi and Mamoru) and Diana (future daughter of Luna and Artemis) from ''Franchise/SailorMoon''. As a result, this trope is sometimes referred to as "pulling a Chibi-usa".
* Sheena to Damos from the thirteenth ''Anime/PokemonArceusAndTheJewelOfLife''. Well, she's more like his Distant Descendant from the Future.
* The entire plot of the manga/anime series ''Manga/MotherIsAFourthGrader'' -- a ten-year-old having to deal with taking care of her infant child who has fallen through a time-warp from the future.
* [[spoiler:Chao Lingshen]] in ''Manga/MahouSenseiNegima'', although she's a little further down the family tree. She fulfills the harem-anime version of this trope by pulling out a book detailing her ancestry to deliberately (and successfully) spark total mayhem among Negi's UnwantedHarem. Side Joke: [[HilariousInHindsight Two chapters before we find out their relationship, one of the scanlators released a joke image]] with her doing a LukeIAmYourFather.
* Inverted in ''Negima's'' sequel ''Manga/UQHolder''. Touta ends up meeting and becoming friends with a younger version of his adoptive mother while training at Danna's palace.[[note]]She's actually a temporal echo caused by the dimension they're in existing outside the normal flow of time.[[/note]] Played straight for about five minutes at the end of the arc when he enters a literal window to her past.
* ''Manga/LittleJumper'': It features a high school student (Hiroki) who suddenly meets a girl (Chimari) who illegally time-traveled from the future to cure her ailing mother via genetic manipulation - and he is her (future) father. Two complications: 1) she hates her father (him), and 2) neither of them have any idea who her mother could [[TimeTravelTenseTrouble (will?)]] be. A surprisingly widely agreed-on theory is that [[spoiler:she could very well be her own future mother]], which would effectively [[spoiler:create both a StableTimeLoop ''and'' a decent amount of fan-discomfort.]] How it all concludes: [[spoiler:Chimari isn't actually Hiroki's kid, she's the result of Ai-chan being a TrulySingleParent, via some [[MagicFromTechnology Techno]]-MysticalPregnancy involving time travel. The cause is likely the Time Jumper, but it could some other time travel method.]]
* ''Anime/TenchiMuyo'':
** In ''Tenchi Muyo [[TheMovie in Love]]'', Tenchi Masaki himself goes back in time to rescue his parents from Kain.
** Subverted in the second movie, ''Daughter of Darkness [=/=] Manatsu no Eve''; Mayuka shows all the symptoms (and some of the characters just accept that she must be from the future, despite the bizarre (and [[YouFailBiologyForever scientifically impossible]]) means used to prevent Washu from identifying the mother through DNA analysis), but turns out to be an ArtificialHuman LaserGuidedTykebomb.
* ''Manga/UruseiYatsura'' uses a variation of this in chapter 11. Ataru tries to avoid arriving late to school by using time travel, but he ends up 12 years in the future and meets up with his [[spoiler:and Shinobu's]] son.
* Nanami in ''VisualNovel/SoulLink'', the HalfHumanHybrid daughter of Nao and Shuuhei. As it turns out, she and she alone holds the key to defeating the BigBad. Even though Nao and Shuuhei only had sex once (and both of them are still high school age), they have no problem taking responsibility as parents for Nanami, who apparently came into being even with Aries being a BuildingOfAdventure.
* An episode of ''Anime/OjamajoDoremi'''s OAV had Doremi's granddaughter from the future travel to the present. [[note]]This, of course, raises the question of who Doremi hooks up with... and then, whose kid ''their'' kid hooks up with.[[/note]]
* ''Anime/{{Doraemon}}'':
** Nobita basically does Dane Cook's stand-up joke from above in an early '90s episode to his parents, who had just had him as a baby, except with less twisted intentions. But hey, might as well warn them their kid's going to grow up into a (ten-year-old) loser, right? Though of course he might've cursed himself this way...
** Sewachi, Nobita's great-great-whatever grandson, is the one who sent Doraemon to his ancestor in the first place. He also spoiled all of Nobita's failure future. Nobita's fate would have been so bad his descendant didn't care of any effect he causes from [[ScrewDestiny screwing destiny]], since he believes he can be born nevertheless.
** Also, [[spoiler:Shizuka and Nobita's son,]] Nobisuke. Even he is angry when Giant tries to hurt his father.
** Later, Doraemon brings [[spoiler:Nobisuke's son]] aka [[spoiler:Nobita's grandson]] to the present time in the same episode.
* Suzune of ''Manga/KamichamaKarin'' came back to SetRightWhatOnceWentWrong and [[spoiler:prevent the eventual death of his father, though he doesn't know that part]].
* Aura of ''Manga/MythicQuest'' is more an [[InstantAIJustAddWater AI]] daughter from another dimension who suddenly introduces herself to her "father," but she plays about the same role in her parents' relationship.
* NSFW Manga ''Yomeiro Choice'' has three (and counting, [[spoiler:up to four and a cybernetic assistant/daughter]]!) daughters from the future, each trying to get the protagonist to impregnate her mother so she doesn't cease to exist. [[spoiler:It ends with the protagonist [[MarryThemAll choosing all of them]]. All of the future daughters not only still exist, they are now sisters.]]
* In ''VisualNovel/SteinsGate'' [[spoiler:Suzuha]] is this to [[spoiler: Daru]], although neither know at first, as the kid in question has very little information to go on regarding the identity of their parents, since it would have to be a very carefully-guarded secret to prevent rival time-travelers from being able to target them.
* ''Manga/MyMonsterSecret'':
** Rin Kiryuin is the teenaged, time-traveling granddaughter of protagonist Asahi Kuromine, which she quickly proves by [[CannotKeepASecret blabbing her secret to him despite being ordered not to do so]]. She doesn't tell anyone else, though, which results in her cute granddaughter-ly interactions with Asahi [[NotWhatItLooksLike causing some confusion]]. Ironically, the only secret she ''can'' keep is the one that would solve most of Asahi's problems: the identity of his future wife.
** 70 chapters later, another kid from the future is introduced with [[HighlyVisibleNinja Momochi]] [[LoveFreak Yuka]], although for a while her being from the future is just shown through obvious hints instead of outright revealed. [[spoiler:Turns out she is the granddaughter of [[LovableSexManiac Shiho]] (friend of Asahi's girlfriend Youko)]].
* ''Manga/SgtFrog'': One episode has Fuyuki and the platoon dragged into the '80s, where Fuyuki meets a younger version of his mother, Aki.
* ''LightNovel/StrikeTheBlood'':
** Discussed during the "Fiesta for the Observers" arc, when a little girl (actually [[spoiler: Natsuki after a witch turned her into a little girl and stole most of her memories]]) starts following Asagi around and seems to believe she's her mother. Asagi considers this trope, but dismisses it because the girl doesn't look enough like her [[PatientChildhoodLoveInterest or Kojou, the guy she has feelings for]].
** [[spoiler:Played straight]] in the "Empire of the Dawn" arc, with the arrival of [[spoiler: a girl strongly resembling Yukina but with Kojou's eyes named Reina. She also has vampiric abilities similar to Kojou's, and can summon a golden spear that resembles Yukina's. She reveals she was sent twenty years into the past in pursuit of a powerful artificially-created monster intent on retroactively destroying Itogami Island before it can become the titular sovereign nation. After helping the main cast defeat the monster, she returns to the future, but not before unambiguously stating that she's Yukina's daughter. Yukina and Kojou awkwardly try to act like this doesn't establish a ForegoneConclusion for their UnresolvedSexualTension. After the credits, TheStinger reveals that this girl also has a half-sister, the daughter of Koujo and [[BalancedHarem Asagi]].]]
* In ''Manga/{{Magical Girl Lyrical Nanoha INNOCENT}}S'', Vivio travels from the future (along with Einhart) and meets up with [[HasTwoMommies her mothers]] Nanoha and Fate. And unlike in [[Franchise/LyricalNanoha the main canon]] where she's adopted, it's implied that she's actually [[HomosexualReproduction their biological daughter]] in this continuity.
* In ''Manga/{{Chinpui}}'', Eri meets a time traveller who turns out to be the son she will someday have with Prince Lulealv. Twice, in fact - the second time she meets him, [[ItMakesSenseInContext he's a baby]].

[[folder:Comic Books]]
* Multiple instances with variation in the [[TangledFamilyTree Summers Family Tree]] of ''ComicBook/XMen'' fame.
** ComicBook/RachelSummers (Phoenix/Marvel Girl) is this trope played absolutely straight and is probably the TropeCodifier (predating [[Franchise/SailorMoon Chibi-Usa]] and [[Manga/DragonBall Future Trunks]], the most famous examples of the trope, by about a decade): she's the daughter of Scott Summers and Jean Grey in the "Days of Future Past" timeline's future, who goes back in time and joins various X-Teams.
** ''ComicBook/{{Cable}}'' is a variation on this. He's the son of Scott Summers and Madeline Pryor (a clone of Jean Grey). He was actually born in the present (now past), but was taken to the future by the Mother Askani (actually future-future Rachel, his half-sister/genetic full sister). No, not the future she came from, another further distant future. There he gets cloned and grows up, later coming back as Cable to a period not long after he was born (but before he was taken to the future). His clone Stryfe follows him back. Note that, briefly, Cable and baby Nathan existed concurrently but never interacted.
** Nate Grey (a.k.a. ''ComicBook/XMan'') looks like this, but is not from the future: he's from the present of an alternate timeline, where he was genetically engineered from Scott and Jean's genetic material and given a PlotRelevantAgeUp. He eventually wound up in the main timeline.
** If you've followed all of this, you may have noticed that Scott Summers and Jean Grey effectively have had four children running around even though Jean was never pregnant. Three of those children are genetically identical, despite it being ludicrously implausible that the genetically engineered Nate Grey would end up with ''exactly'' the same DNA as Cable, who was conceived naturally in a different universe.
** Other ''X-Men'' future Summers kids not tied to ''both'' of the above parents: ComicBook/{{Cyclops}} has a daughter with Emma Frost, in the form of X-Factor's Ruby Summers.
** Also in ''ComicBook/XFactor'', it is revealed that Shatterstar is the son of [[spoiler:Dazzler and Longshot]] who had been raised in the future of another dimension. This had been hinted at many times almost from the moment Shatterstar was introduced. Surprise, surprise! It's now confirmed that Shatterstar is [[spoiler: Longshot's]] son, but also (due to time-travel whackery), that Shatterstar is [[spoiler: Longshot's]] father!
** Another alternate-universe twist on this trope from X-Continuity is [[ComicBook/{{Exiles}} Nocturne]], Nightcrawler's daughter with the Scarlet Witch, of all people.
** Minor case: Bishop of the X-Men is from the future, and turns out to be the grandson of minor character Gateway.
* In ''ComicBook/BattleOfTheAtom'', [[spoiler:Future Kitty is really Mystique and Wolverine's future son Raze, a mutant who inherited both of his parents' powers.]]
* For a non-X-Men example in the Franchise/MarvelUniverse, this has also happened in ''ComicBook/FantasticFour'' with Valeria [[spoiler:Von Doom]], daughter of [[spoiler:Sue Richards and Doctor Doom ([[{{Retcon}} or Reed Richards impersonating Doom]], though she certainly ''thought'' Doom was her father)]]. Like Rachel Summers, she's a creation of Creator/ChrisClaremont, and they've even both used the CodeName "Marvel Girl" (though in all fairness, Rachel had yet to use that name at the time of Valeria's creation). Clearly, Claremont ''loves'' this trope.
* In another ''ComicBook/FantasticFour'' storyline, Reed and Sue's son Franklin Richards pulls a Cable, getting sent into the distant future and returning as the adult "Psi-Lord". Oddly enough, during the brief time that the adult Franklin was in the modern era, he never encountered Rachel Summers despite his "Days of Future Past" counterpart being her boyfriend.
* Then, Hyperstorm came. Who is Hyperstorm? Child of [[ComicBook/FantasticFour Franklin Richards]] and ComicBook/RachelSummers in the ''Days of the Future Past'' alternate future. Yes, The two families who did it most in the Marvel Universe are now mixed together! Unfortunately, he's a completely insane villain. He's also the reason the 616 version of his father is a kid again, having pulled a RetGone on the adult version.
** For that matter, [[{{Comicbook/Avengers}} Kang The Conqueror]] always claimed to be a descendant of Doctor Doom. It turns out he's actually a descendant of Reed's dad Nathaniel, making Reed his great-great-great-great-great-great-whatever uncle. Although now a recent RetCon seems to declare that that was only an [[TangledFamilyTree alternate-universe version of Nathaniel!]]
* From ''ComicBook/TheFlash'':
** [[ComicBook/{{Impulse}} Bart Allen (Impulse/Kid Flash II)]] was the Wally West's (The Flash III) cousin from the 30th Century--and the grandson of Barry Allen (The Flash II) who had spent a long time in the 30th Century before his death. Bart is also technically also the great-great-great (you know how this goes) grandson of the Eobard Thawne (The Reverse-Flash I) on his mother's side.
** [[ComicBook/LegionOfSuperHeroes Jenny Ognats (XS)]] is Bart's cousin, and thus also Wally's cousin and Barry's granddaughter. She too was born in the 30th Century.
** Iris West II, the (seemingly) third Kid Flash, is Wally's future daughter. She was introduced in the 90s, and eventually by the mid-00s Wally and his wife Linda had twins, one of whom was named Iris and would become the second Impulse.
** In "Chain Lightning", Wally West, Jesse Quick, Jay Garrick, Max Mercury and Impulse are requried to travel through time recruiting the Flashes of various eras, and one of them is a man named [[DeadguyJunior Jace Allen]], a descendant of Barry Allen's.
** Owen Mercer (Captain Boomerang II), is Impulse's half-brother, conceived while the original Captain Boomerang, Digger Harkness, ended up in the 30th Century and lost his memory. Digger somehow ends up back in the present, but isn't aware of Owen's existence until Owen is already an adult. Owen is also the great-great-great (you know how this goes) grandson of Eobard Thawne.
* Another case of the lead being the child is the current ''ComicBook/BoosterGold'' series, in which his distant ancestors are recurring characters. Booster explicitly references Marty [=McFly=] at one point.
** In addition to this, Rip Hunter, who's playing mentor to Booster, has been revealed as [[spoiler:''Booster's son''. The mother remains a mystery thus far.]] He deliberately keeps his parentage a secret so that other time travelers can't RetGone him by targeting them.
* In one ''Comicbook/AstroCity'' plotline, several versions of Jack-In-The-Box's son from the future appear (The Box, The Jackson, and Jerome Johnson). They [[spoiler:grew up without a father]] because, in their timelines, [[spoiler:Jack-In-The-Box died before his son's birth. One turned out to be a bloodthirsty vigilante, another ended up totally insane, and the third, 'normal' one was clearly emotionally wounded]]. This convinces Jack-In-The-Box to [[spoiler:[[PassingTheTorch hand off his identity to a younger protege]] and concentrate on his family.]]
* Lara-Su, the daughter of Knuckles and Julie-Su from two different possible futures in Archie Comics' ''Comicbook/SonicTheHedgehog'':
** The first version of Lara-Su to appear, also known by the alias "Jani-Ca", first showed up in the early 100's issues. She came from a BadFuture (a ''very'' bad future recently dubbed "Dark Mobius" by WordOfGod), and attempted to [[SetRightWhatOnceWentWrong avert it]] by preventing Knuckles' assassination. Except, when she got back to her time, not only did she find out that she had gone back into [[AlternateUniverse the wrong timeline]], but that her mother had lied to her to protect her - Knuckles hadn't died, he'd pulled a FaceHeelTurn and was responsible for that bad future.
** The second version of Lara-Su was from the much nicer "Mobius: X Years Later" timeline. She was one of the few people [[RippleEffectProofMemory not affected]] by the CosmicRetcon and helped Future Sonic depose [[KnightTemplar King Shadow]], and a while after that became a member of the Future Freedom Fighters.[[note]] It should also be noted that this version of Lara-Su never went back in time - so she's not so much a Kid From The Future as she is a Future Kid.[[/note]]
** And there's also Silver the Hedgehog, who continually makes trips from a ruined future trying to find the "Freedom Fighter Traitor" responsible for causing it. Unfortunately for him, he's wrong every time, and every trip to the past ends up changing the future (their present), and not for the better. Eventually, his mentor, [[spoiler:Future Mammoth Mogul]], sends him into the past and tells him to stay there until he's found the traitor. He ends up joining the Secret Freedom Fighters. But just when he's about to find the true traitor, the CosmicRetcon occurs.
* Done in the final issue of ''ComicBook/BillAndTedsExcellentComicBook'', where the two main characters are visited by their grown-up children from the future.
* Lyra is the daughter of ComicBook/TheIncredibleHulk and the parallel universe future AntiHero Thundra.
* In ''ComicBook/GoldDigger'', Brianna Digger's daughter Roquette came back in time to stop her mother from marrying the wrong person! ... only to discover Brianna was merely ''planning the wedding'' of some other person and Roquette's timeline was unthreatened. Oops?
* Lord Chaos, the BigBad of the ''Comicbook/TeenTitans'' storyline "Total Chaos" is a future version of Donna Troy's son, who travels back to ''the day she gives birth'' (he's pursuing the Team Titans who are attempting their equivalent of "killing Hitler as a baby").
* In the ''{{ComicBook/Tammy}}'' comic “Thursday's Child”, Thursday Brown is tormented by a girl named Julie, then learns that Julie is her daughter from the (then-future) year 2000, who has come back to make her mother's life a misery to punish her for a car accident in which Julie ended up paralyzed.

[[folder:Fan Works]]
* This is the whole point of the ''LightNovel/HaruhiSuzumiya'' fic [[http://www.fanfiction.net/s/6254986/1/The_Anagram_of_Suzumiya_Kurumi The Anagram of Suzumiya Kurumi]]. Notably, it is ''much'' more of a MindScrew than it seems at first, due to ridiculous amounts of time-travel-related AnachronicOrder.
* ''Fanfic/HigherLearning'': Subverted. [[spoiler:Kaoru]] is a descendent of Shinji and Asuka came from the future, but he is not their child but their grandchild, and he is an adult.
* ''Fanfic/TheSecondTry'': Variant. [[spoiler:Aki Ikari is Shinji and Asuka's future child. She gets sent back in time about a day before SEELE launches their attack on NERV. Her parents were already aware of her existence, having been sent back in time themselves.]] Her character is explored further in the sequel ''Webcomic/AkiChansLife''
* In the ''WesternAnimation/AvatarTheLastAirbender'' fanfic [[http://www.fanfiction.net/s/4229235/1/Tea_With_Destiny Tea With Destiny,]] Iroh travels to the Spirit World following the death of his son and intends to stay there forever. His son, however, doesn't think that's a good idea and takes him to visit with a very wise old man who turns out to be future!Zuko (Iroh isn't aware of this, as Zuko is currently ten years old in the real world). Future!Zuko advises Iroh to go back to the mortal world and be his mentor, because he's [[HeelFaceRevolvingDoor really]] going to need it.
* ''WesternAnimation/CodenameKidsNextDoor'' has inspired many fanfics that use this trope, such as [[http://www.fanfiction.net/s/5782902/1/KND_Operation_Meet this example]]. These fanfics tend to involve future KND Operatives meeting the present-day KND via time travel, or the present-day KND time-traveling and meeting future KND Operatives.
* ''{{Series/Glee}}'' - It's become a Brittana fandom meme that Sugar Motta is actually [[http://tilhe.tumblr.com/post/13536671495/afterlaughs-back-to-the-future-glee-yes Brittany and Santana's time-traveling daughter]]. Variations include whether she ended up in the past on purpose or by accident. Vanessa Lengies thinks it's hilarious.
** Other fanfics include [[http://teamklaine.tumblr.com/post/14073439700/happyinyourarms-back-to-the-future-part-iv Rory as the adopted son of Kurt and Blaine]], and Harmony as the daughter of either Rachel and Quinn, or Rachel and Jesse St.James
* ''FanFic/{{Hands}}'' by Andrew Joshua Talon has an unresolved LoveTriangle between a human, Fluttershy and Twilight Sparkle. In the TimeTravelEpisode after those three agree that {{Stable Time Loop}}s are useless and cause only problems they get back to discussing how to resolve their Love Triangle. Seconds later two half human hybrids colored like Twilight Sparkle AND Fluttershy respectively arrive via Time Travel to tell their parents to just get a move on. [[spoiler: They are actually [[PhysicalGod Princess Luna]] and [[FunPersonified Pinkie Pie]] who traveled back from later that day to prank them.]]
* The Harry Potter fanfic [[http://www.fanfiction.net/s/8965827/1/Far-From-Home-and-All-Alone Far From Home and All Alone]] uses this trope with Remus Lupin, his future son Teddy and Harry's future daughter Lily. The two are sent to the past while Teddy is supposed to be protecting Lily and instead get in the middle of some dark wizards' nefarious schemes. [[spoiler: Remus does not learn Teddy is his son until the end though.]]
* In ''Fanfic/TwistOfFate'', the time-traveler Moses declares that Gunha Sogiita is Touma Kamijou and Misaki Shokuhou's son from the future who was brought into the present. The incredibly shocked and embarrassed Touma and Misaki suspect Moses was just messing with them, especially since Moses was snickering when he said it, but the incredibly gullible Gunha immediately believes it. Touma and Misaki are essentially forced to take responsibility for Gunha, even though they are roughly the same age, even going to a parent-teacher conference for him. It helps that they are much more mature than him. On the other hand, the girls in Touma's harem are not pleased because if Moses was telling the truth, this means Misaki won. [[spoiler:Much later, Gunha somberly admits that he knew Moses was lying, but he went along with it because he liked Touma and Misaki and ''really'' wanted them to be his parents.]]
* This is the only way to rationalize {{original character}}s in ProfessionalWrestling fanfics who are the sons and daughters of wrestlers that are barely half their age and whose stories are unironically set in "present-day" timelines.
* Suzaku is a variant of this trope in ''FanFic/MyMirrorSwordAndShield'' as he's Cecile's [[HappilyAdopted adoptive son]] from the future. This is lampshaded by Lloyd who wonders how Suzaku could be her kid when he doesn't look like her. Suzaku deconstructs this as he decides not to help his biological parents. He acknowledges that he could meet his father and make sure he doesn't die and prevent his mother from becoming a neglectful drug addict but he much rather help his adoptive family.
* ''Fanfic/CardinalKing'', being a Franchise/SailorMoon fanfic, has an example. As the story revolves around Mamoru being the HenshinHero and not Usagi, the kid in question is [[OriginalCharacter Mamorin]], a boy with [[CurtainsMatchTheWindows red hair and red eyes]], instead of Chibi-Usa.
* ''Fanfic/PonyPOVSeries'': Nightdrake Bannerette, a grown-up, alternate universe version of Spike, appears and saves Rarity and the Cutie Mark Crusaders from Abandon. Before he leaves, he asks the CMC to tell Spike not to give up on pursuing Rarity. When they tell him, Spike mistakenly believes Bannerette is his and Rarity's kid from the future and that this proves he and Rarity are destined to be together. The CMC attempt to explain that this is not the case, but give up and just let him think that.
* In ''[[https://www.fanfiction.net/s/4363514/1/Flashback Flashback]]'', [[WesternAnimation/TeenTitans Beast Boy and Raven]]'s son goes back in time to help his parents with an alien invasion. [[spoiler:In the end, he performs a HeroicSacrifice to get rid of the aliens... and two years later, Raven gives birth to a girl.]]
* In ''[[https://www.fanfiction.net/s/7172115/1/Surprise-of-your-Life Surprise of Your Life]]'' Remus's son Teddy and Harry and Charlie Weasley's son Connor accidentally show up at Grimmauld Place during the summer after Harry's fourth year.
* Several stories have an infant Literature/HarryPotter sent back to his parents while they were still students at Hogwarts. In a few of them, caring for him is what brings them together as a couple.
* ''Fanfic/OversaturatedWorld'': Dinky Doo is Ditzy's, sent back from the future by Ditzy's future self so Dinky can spend time with a version of her mother.
* ''Fanfic/TheBridge'': A future Flurry Heart, whom hasn't even been born yet in the setting, ''Empress'' Flurry Heart temporarily time travels using a spell taught to her by her aunt, Twilight Sparkle. While trying to avert a BadFuture, her method of SetRightWhatOnceWentWrong is less her direct actions and more arranging events to happen right.
* The ''WesternAnimation/JackieChanAdventures'' fanfic ''[[Fanfic/TheUltimateEvil The Stronger Evil]]'' has Drago, Shendu's son from the future, as per JCA canon. Here, however, it's further expanded on by showing that [[spoiler: the Chan family's friend [[OriginalCharacter Valerie Payne]] is his mother]].
* Near the climax of the StoryArc of the fifth ''Fanfic/HalloweenUnspectacular'', the heroes are joined by Tammy Turner, the future daughter of Timmy Turner [[spoiler: and Dani Phantom]], who has come back in time to [[SetRightWhatOnceWentWrong avert]] the horrible BadFuture she's from.

[[folder:Films -- Animation]]
* In ''Disney/MeetTheRobinsons,'' [[spoiler:Wilbur is Lewis' son. This explains his reluctance to help Lewis go back in time and meet his birth mother--Wilbur knows that Lewis is destined to be HappilyAdopted if he just holds out a little longer]]. Interestingly, the LoveInterest winds up introduced at the ''end'' of the time-travel adventure, but still with the clear indication that the two will hook up eventually.

[[folder:Films -- Live-Action]]
* The ''Franchise/BackToTheFuture'' trilogy:
** ''Film/BackToTheFuture'': Marty [=McFly=] is the kid from the future. He's also the main character and accidentally nearly prevents his own parents from getting together in the first place.
** ''Film/BackToTheFuturePartII'': Marty travels back to 1955 again.
** ''Film/BackToTheFuturePartIII'': Marty travels even further into the past and meets his ancestors, thus making him a Great-Great-Grandkid from the Future.
* Lampshaded in ''Series/GuestFromTheFuture'' when Alisa jokes to Yulia "Maybe I'm your granddaughter."
* The 2011 film, ''Film/EnterNowhere'' [[spoiler: has a child from the future, grandchild from the future, and a great-grandchild from the future. Tom is Jody's son, Jody is Samantha's daughter, and Samantha is Hans's daughter.]]

* In ''Literature/BonesOfTheEarth'', some time-traveling paleontologists get stranded in the Mesozoic for months. Once rescued, they're welcomed home by hordes of media and friends from many different times ... including an adult version of the baby one of their group gave birth to in the Mesozoic. He doesn't save them, but he gets to hold his infant self.
* Done weirdly in the ''Series/DoctorWho'' Literature/EighthDoctorAdventures novel ''Father Time''. Neither the Doctor nor his KidFromTheFuture, Miranda, knows that he's her biological father, despite the fact they look decidedly alike (when she grows up, they're even about the same height) and she's the [[WhereIWasBornAndRazed only other member]] of his [[HumanAlien species]] he [[TraumaInducedAmnesia remembers]] meeting. He [[ChildrenRaiseYou adopts her]] and raises her like his own, not realizing that she actually is. ([[TimeyWimeyBall Confusing things further]], if Miranda's father ''is'' a future version of the Doctor [the books are only implicit on this point], then it's almost certainly a future that never actually happened; and was unlikely to happen even by the time of ''Father Time'').
* This trope is central to ''Literature/TheGlassRuins'', where the main character is sent into the past [[spoiler:to prevent his mother who is pregnant with him from having an abortion.]]
* Alba from ''Literature/TheTimeTravelersWife'' (approximately--she appears after Henry and Clare are married but when they think they can't have kids, and Henry comes forward in time to see her about as much as she goes back to see him). In one of the final scenes in the book, Alba visits Henry before he meets Clare. Even after she says she was looking for her father but was apparently too early, he still fails to understand who she is.
* In ''Literature/TheDivineComedy'', Dante speaks to his great-great-grandfather in the Mars sphere of Heaven. Contrary to most uses of the trope, it is Dante's ancestor who "predicts" Dante's future, namely, his exile from Florence.

[[folder:Live-Action TV]]
* Wyatt and Chris on ''Series/{{Charmed}}'', the children of Piper and Leo. Future Wyatt only shows up after Baby Wyatt has been born, but Future Chris preceded Baby Chris and his identity was an object of speculation.
** Interestingly, the girls undergo MentalTimeTravel in a season two episode, and Piper meets her young ''daughter'' Melinda; a few years later, she and Leo get pregnant specifically because it's about time for Melinda to be conceived, and were surprised when Wyatt was born instead. Of course, as Piper noted, she met Melinda in a BadFuture that they managed to avert, so clearly this wasn't an ironclad destiny anyway.
** Chris almost causes himself not to exist the same way Marty [=McFly=] did, by breaking up his parents. Except he did it on purpose, apparently not ever bothering to do the math and figure out when he was conceived. This was due to RealLifeWritesThePlot. Chris was always going to be their son, and that reveal had already happened, but Piper's actress got pregnant halfway through the season, while Chris was deliberately keeping Leo away so Leo wouldn't figure out who Chris was and what he was doing. So the writers had to scrabble to get in a one-night Leo-Piper hookup arranged by Chris to explain the pregnancy, and Chris looks like a complete idiot for almost erasing himself from existence.
** A rumor says that Chris was originally supposed to be ''Phoebe and Cole's'' son from the future, meant to give Phoebe a reason to have hope for her bad luck in romance. It makes sense given his original actions earlier in the season--he had strong connections to demons and moved around in the underworld to access magic that would protect his identity from the Charmed Ones. The pressure was really on to identify whose kid he was after Creator/HollyMarieCombs became pregnant though, and it's incredibly fortunate that the series hadn't revealed Chris' origins beforehand for the writers' sake. (It's also worth noting that the writers ''originally'' intended to use Wyatt, who was already born by that point, but thought it would be too obvious.)
** In one episode, Future Chris' girlfriend Bianca shows up, and runs into her mother at one point.
** The girls themselves also went back in time at one point and met their mother (who had died when they were young children). They figured out that she'd already be just barely pregnant with Phoebe at this point, and Piper sort of spoils it for her when trying to prove they have a connection (the mother believes she can't get pregnant anymore).
* ''Series/DoctorWho'' has multiple examples, dealing with TimeTravel on a regular basis.
** [[Recap/DoctorWhoS27E8FathersDay "Father's Day"]] has companion Rose Tyler meet her mother, father, and infant self.
-->'''Jackie:''' Her dad? How are you her dad? [[{{Squick}} How old were you, twelve?]]\\
'''Pete:''' Jacks - listen. This is Rose.\\
'''Jackie:''' Rose? How sick is that? You give my daughter a second hand name? How many are there? Do you call them ALL Rose?\\
'''Pete:''' Oh, for God's sake, look! It's the SAME Rose!
** River Song, [[Recap/DoctorWhoS30E8SilenceInTheLibrary first]] [[Recap/DoctorWhoS30E9ForestOfTheDead introduced]] to (''and'' killed off soon after meeting) the Tenth Doctor in 2008, turns out to be the daughter of Eleventh Doctor companions Amy and Rory, [[Recap/DoctorWhoS31E1TheEleventhHour introduced]] in 2010. Her example is among the most extreme on this page -- thanks to the TimeyWimeyBall ''and'' [[TheNthDoctor Time Lord regeneration]], she actually [[Recap/DoctorWhoS32E8LetsKillHitler spends her entire teenage years]] growing alongside her parents as their contemporary BlackBestFriend, even playing a role in getting them together. She also visited her parents' wedding and later married the Really700YearsOld Doctor herself, making her 20+ something old parents his in-laws.
** In [[Recap/DoctorWhoS33E9Hide "Hide"]], the Doctor meets a scientist and a psychic investigating a haunting, and discovers the "ghost" to actually be a time traveler stuck in a pocket universe. After they rescue the girl, the Doctor reveals the time traveler to be one of the scientist and psychic's descendants, even though they weren't even technically a couple yet -- they had just finally begun to recognize the mutual UST.
** Subverted when Clara [[Recap/DoctorWhoS34E4Listen meets and rescues]] another time travel pioneer named Orson Pink and, due to his resemblance to her [[RomanticFalseLead then-love interest]] Danny Pink, his mention of a time-travelling great-grandparent, and her witnessing of the above example, assumes that he's a descendant of hers and that she and Danny are "supposed" to end up together, leading her to continue a date that was going badly before time travel got involved. While Orson is likely related to Danny in some way, he turns out ''[[RedHerring not]]'' [[RedHerring to be a direct descendant]]: Clara's relationship disintegrates as a result of their incompatible lifestyles and her lies about her adventurous double life, and Danny himself dies in a sudden, tragic traffic accident just as she was trying to patch things up.
** ''Series/TheSarahJaneAdventures'' episode "The Temptation of Sarah Jane Smith" uses [[RecycledScript the same plot]] as "Father's Day", incorporating both Kid and Grandkid from the Future.
* In the final season of ''Series/GoodnightSweetheart'', Gary (who regularly time-travels back to UsefulNotes/WorldWarII, and maintains a second life there) is taken aback to meet his Kid In The Present.
* Claire Bennet plays this role in a season 3 episode of ''Series/{{Heroes}}'', as does Hiro Nakamura.
* Wataru becomes one to Otoya in ''Series/KamenRiderKiva'' when he decides to travel back in time both in-series and in-movie. Ironically, he does so because [[spoiler:he's in despair at accidentally killing his love interest Mio, so he tries to convince [[ReallyGetsAround Otoya]] and [[TheVamp Maya]] ''not'' to have him. In the end, both convince him to choose to live.]] Given the strong GenerationXerox Kiva has, [[spoiler:Wataru's son from 22 years in the future appears in the finale, along with Kivat the 4th, who gives him the power to become New Kiva.]]
* ''Series/KamenRiderDenO'' is a natural candidate for this, given its plot. The series proper has [[spoiler:Hana, who as the child of Yuto and Airi, is Ryotaro's future niece, which makes all that ShipTease turn a little sour in retrospect...]]. TheMovie ''Final Countdown'' introduces Kotaro, Ryotaro's grandson, who is also New Den-O.
* ''Series/KamenRiderDrive''[='s=] summer movie ''Surprise Future'' involves Shinnosuke's son Eiji traveling back in time from 2035 to prevent a BadFuture apparently caused by [[TheMentor Krim Steinbelt]] and an EvilCounterpart of Drive. [[spoiler:And then it turns out the Eiji we've been following most of the movie is actually the BigBad in disguise, and the ''real'' Eiji was defeated in the future and had his Belt taken.]] Eiji also teases at his mother's identity when he tells Shinnosuke [[spoiler:[[WhenSheSmiles "She doesn't smile very often, but when she does it's very meaningful"]], which is a spot-on description of Shinnosuke's partner Kiriko.]]
* This may be what happens in the final episode of ''Series/KamenRiderGhost''. Ayumu, a mysterious boy seemingly from a [[BadFuture dystopian future]], armed with knowledge of who Takeru is and what he did as Ghost, appears searching for a powerful object capable of changing the course of history. [[EarlyBirdCameo With the help of]] [[Series/KamenRiderExAid his successor]], Takeru sets the boy's sullen attitude straight and convinces him that the future can be changed if people work together. Ayumu thanks Takeru as he steps back into the portal to his own time; although his words become inaudible at this point, he is very clearly mouthing "otou-san"[[note]] dad[[/note]] as he vanishes, though unlike in the other cases on this page, it's never explicitly stated.
* The ending of the last ep of ''Series/LoisAndClark'' was a setup for this trope.
** Even though the same episode had DNA testing establish that Clark could never have a child with a human woman. Of course, it's not entirely unlikely that an advanced species like the Kryptonians could have devised a way to make such a pairing work.
* ''Series/{{Krypton}}'': [[spoiler:General Zod]] meets with his dead family on their not-yet-exploded planet while time-traveling to kill Brainiac.
* On ''Series/{{Lost}}'', time travel begins playing a role in the fifth season. After being transported back to the 1970s:
** Miles interacts with his parents and sees himself as an infant. Miles wishes to have no relationship with his father because he allegedly abandoned Miles and his mother. Through predestination paradox, it is revealed Miles' friend Daniel Faraday was responsible for this: Miles' father didn't abandon his son, he forcibly made them leave the island to survive a catastrophic incident that would happen hours later, having been told of this by Daniel.
** Daniel himself believes he can stop said incident by finding his mother, Eloise Hawking, a member of the Others, then having her help him detonate a hydrogen bomb that he told her to bury when he time travelled to 1954. However, when he arrives at camp, [[spoiler:she shoots him in the back]] when he holds up [[ReallySevenHundredYearsOld Richard Alpert]], and as he [[spoiler:dies]] he tells her he is her son. She is forced to live the rest of her life knowing her son will grow up, go back in time, and be [[spoiler:shot dead]] by her unknowing past self.
*** And then she [[spoiler:sends him to the Island in the first place]], knowing too well what's going to happen. It is all really tragic, but she must have really disliked time paradoxes to allow all this to happen.
*** She didn't "allow" anything to happen. "Whatever happened, happened". As she told Desmond, any attempt to change what is fated will be futile, as it will happen anyway.
* On the soap opera ''Series/{{One Life to Live}}'', a one-month story arc in 1988 sent Clint Buchanan back to 1888, where he nearly [[MyOwnGrampa married his wife's great-grandmother]]. Thankfully, she manages to follow him back in time just in time to stop the wedding.
* ''Series/PowerRangersNinjaStorm'' - Cam's journey to become SixthRanger involves using a magic scroll to travel back in time. He witnesses his parents' first meeting (his mom kicking his dad's ass in front of their entire NinjaSchool), and "inherits" his morpher from her before returning to the present.
* Alexander Rozhenko does this in an episode of ''Series/StarTrekTheNextGeneration''. [[spoiler:Due to having grown up to be a pacifist and diplomat, his perceived weakness led to him nearly being assassinated by political rivals, with Worf TakingTheBullet. He traveled back to convince his younger self to become a warrior as his father had wanted, but when this plan fails, he attempts to kill his younger self to ensure that future never came to be. Worf luckily convinces him that the future is not set in stone and even if he pursues the path of peace, it is something [[SoProudOfYou he would be proud of]].]] Interestingly, when Alexander shows up in ''Series/StarTrekDeepSpaceNine'' as a young adult it's shown that the BadFuture has been thoroughly averted, but this incident isn't even mentioned except in passing.
** Two other ''Franchise/StarTrek'' episodes, namely the ''[[Series/StarTrekDeepSpaceNine Deep Space Nine]]'' episode "Childen of Time" and the ''[[Series/StarTrekEnterprise Enterprise]]'' episode "E[[superscript:2]]", had a variant of this trope, in which the descendants of the crew (of the ''Defiant'' and the ''NX-01'' respectively) ended up in the present due to the ship's imminent travel into the past, with no way back. [[spoiler: In both episodes, the time travel eventually gets prevented, but not without paying the high price of the "future" children's existence.]]
* ''Series/{{Supernatural}}'':
** Dean in the episode "In the Beginning".
** And both Sam ''and'' Dean in the episode "The Song Remains the Same".
* Deke Shaw, future grandson of [[spoiler: Fitz-Simmons]] from ''Series/AgentsOfSHIELD''. Bit of a variation, as he's first met when the team time travels to the future, ''then'' he travels back with them (by accident) to the present.
* In ''Series/{{The Flash|2014}}'', a girl keeps showing up throughout Season 4. [[spoiler:She's eventually revealed to be a speedster named Nora - Barry and Iris's future daughter]].

[[folder:Tabletop Games]]
* In the detailed character biographies of ''TabletopGame/KitsuneOfFoxesAndFools'' it's stated that Akomachi's daughters Sharmarali and April, grandkits Akira and Cori, and apprentice Aoki all came back in time to see what she was like before her ascension.

[[folder:Video Games]]
* Trinity from ''[[Videogame/{{Boktai}} Boktai 3]]'', according to WordOfGod, is a distant descendant of Django. He does ''one good thing'' (Break the seal that trapped Django, whose absence led to the BadFuture to begin with) before comfortably settling into his position as TheLoad.
* ''VideoGame/TalesOfDestiny2'' has Kyle, the protagonist, meeting his parents in the past. Stahn even jokes that he'll name his son after Kyle. He never reveals that he's their son, though.
* Arguably, Silver from ''Franchise/{{Sonic the Hedgehog}}''. It's implied that he's the descendant of either Sonic or Shadow, but it's never specified which.
** Although ''[[VideoGame/SonicStorybookSeries Sonic and the Black Knight]]'' is a spin-off whose place in canon is disputable (although ''Generations'' ''does'' distinctly, if not offhandedly mention the events of its direct predecessor, ''Sonic and the Secret Rings''...), it should be noted that Shadow is portrayed there as Sir Lancelot. Silver, although a secret character with no plot importance, also appears in that game as Sir Galahad, ''Lancelot's son''. Make of that what you will.
* The main plot of the best-forgotten game ''TimeDiver''.
* In ''VideoGame/{{Space Quest IV|Roger Wilco and the Time Rippers}}'', Roger is saved by his future son. Roger meets the mother in Part V and [[http://tmd.alienharmony.com/rw/sq5/pictures/ledgea4.gif will cease to be]] if she gets killed.
** Interestingly, Beatrice is barefly mentioned in ''VideoGame/{{Space Quest VI|Roger Wilco in the Spinal Frontier}}'', and Roger is trying to get together with another woman, apparently forgetting the time loop. It's possible, of course, that he simply wants to have a fling with Stellar, while Bea is busy elsewhere. The preview for ''Space Quest 7'' (which was never made) once again has Roger trying to save Beatrice.
* Baby from ''VideoGame/SuperMonkeyBall''.
* In ''VideoGame/ChronoTrigger'', Marle warps back a few centuries [[spoiler:and is [[IdenticalGrandfather mistaken for her great-great-etc.-grandmother]].]]
** [[spoiler:She's also implied to be Ayla's Descendant From The Future.]]
* In the Ambitions expansion pack for ''VideoGame/TheSims 3'', it is possible to end up with one of these when using the time machine.
* ''[[VideoGame/InazumaEleven InazumaEleven 3: the Ogre]]'' features Endou Kanon, a kid from the future who tries to stop an evil organization that tries to get rid of Kanon's great great grandfather, Endou Mamoru, and his Japanese international soccer team.
* In ''Videogame/MagicalGirlLyricalNanohaAsPortable: The Gears of Destiny'', [[LesYay Nanoha and Fate]] meet [[HasTwoMommies their (adoptive) daughter]] Vivio from the future. The real kicker is that all three of them are ''about the same age'' (that is, ten years old). Oh, and to make the matters worse, Vivio brings her own girlfriend Einhard along for the ride. Also, Vivio and Einhard are able to transform into [[OlderAlterEgo adults/teenagers]].
** It's even funnier: regardless if Vivio is in her Adult Mode or not, Nanoha acts like a mother to her like she will do in the next 9 to 13 years.
* ''VideoGame/{{Achron}}'' has a partial example. It's possible for a factory (parent) to produce a unit (child) which then gets sent back to before it was built (born) to defend the factory.
* All over the place in ''VideoGame/FireEmblemAwakening''. [[spoiler:"Marth" reveals her true identity as the grown-up version of Chrom's daughter Lucina, who comes from a BadFuture that she and her friends want to avert.]] After this reveal, when a male and female campaign character reach S support level, the player can recruit their kid in a side chapter. There are a total of 13 future children; at least one of them ([[spoiler:Morgan]]) will be mothered or fathered by the PlayerCharacter. To make things even "funnier", said future kid can end up as the future kid of one of the other 12 future kids if the PC marries one of them, meaning to two characters that character is a ''Grand''kid from the Future.
** ''VideoGame/FireEmblemHeroes'' allows [[VideoGame/FireEmblemTheBindingBlade Roy and Lilina]] to meet their fathers [[VideoGame/FireEmblemTheBlazingBlade Eliwood and Hector]] in their younger days.
* Petta from the PSP remake of ''VideoGame/MakaiKingdom'' is the daughter of Zetta (the Protagonist and self-proclaimed "Most Badass Freakin' Overlord in the Cosmos",) having traveled from the future... Or so she claims. [[spoiler: Surprisingly, she is indeed the daughter of [[OfficialCouple Zetta and Salome]]; the reason she came from the future is because the prophecy that set the game's plot in motion still persists in her era, so she went back in time to prevent it.]]
* Ele of ''VideoGame/StarGladiator''. She's a cute girl from the future who happens to be the daughter of [[spoiler:Hayato]] and [[spoiler:June]].
* ''VideoGame/JojosBizarreAdventureEyesOfHeaven'': It's possible to team up 24-year old Dio with his teenage son Giorno ([[{{Immortality}} who wasn't conceived for another hundred years]]), 19-year old Joseph with his teenage son Josuke ([[HeroicBastard who wasn't conceived until Joseph was in his 60's]]), and 17-year-old Jotaro with his daughter Jolyne, who is ''older than him'' at the point he meets her in the timeline. Jolyne and Jotaro are of special significance to the plot, as in her time period, he's her DisappearedDad, and they don't have the best relationship, but she's still worried about him. [[spoiler: Meeting, fighting alongside, and subsequently losing her to the villain is what causes him to try and become a better father once the timeline rectifies itself.]]
* A ''really'' weird and MindScrew-y case of this happens in ''VisualNovel/ZeroTimeDilemma''. [[spoiler:In the D-2 Ending, Sigma and Diana give birth to twin babies after being stranded in the shelter and about to starve to death. In a last ditch effort to offer their kids a life in ''some'' timeline, they use the transporter they found that allows them to send a copy of the children through spacetime and back into the past. Those twins' names are Delta, the true identity of this game's [[BigBad Zero]], and Phi, the same Phi that acts as the heroine of ''VisualNovel/VirtuesLastReward'' and a member of the D-Team]].

[[folder:Web Comics]]
* ''[[Webcomic/WalkyVerse It's Walky!]]'' has Bobby "Machete" [[https://web.archive.org/web/20110805040700/http://www.walkypedia.com/index.php/Bobby_Walkerton Walkerton]].
* In ''Webcomic/{{Narbonic}}'', [[spoiler:Dave]] and [[spoiler:Helen]]'s child abuses her parents' [[TheEndOfTheWorldAsWeKnowIt Universe-consuming]] time machine ("We siphon it from universes where they probably don't want to exist as much") to [[spoiler:spy on her parents before they got married -- and arguably creates a StableTimeLoop by convincing Dave to get back with Helen, a decision without which she wouldn't have been conceived]].
* Similarly, in ''Webcomic/UmlautHouse'', Rhonda goes into the past to [[spoiler:settle an argument with Pierce, who follows her to keep her from meddling in the past (as it happens, he shouldn't have bothered)]].
* [[http://www.galactanet.com/comic/view.php?strip=342 J.J.]] from ''Webcomic/CaseyAndAndy''.
* Todd from ''Webcomic/GeneralProtectionFault''.
* Vivio in the ''Anime/MagicalGirlLyricalNanoha'' FanWebcomic by [[http://www.q-ice.com/ Q-Ice]], [[JerkAss who mostly did it to]] [[http://img300.imageshack.us/img300/4199/nano104trwg1.jpg screw]] [[https://web.archive.org/web/20130730152224/http://img300.imageshack.us/img300/9425/nano105tryy0.jpg around]] [[HasTwoMommies with her mothers]].
* [[spoiler: John]] Taylor from ''Webcomic/CogaSuro'', in a direct homage to [[Anime/DragonballZ Trunks]].
* In ''Webcomic/{{Homestuck}}'', Jade's 'penpal' [[spoiler: claims to be her future grandson.]] What this truly means remains to be seen. [[spoiler: [[HappilyAdopted Parentage is]] [[StableTimeLoop a strange]] [[MyOwnGrampa thing in]] ''Homestuck''.]] We later meet him in Act 6, where it turns out [[spoiler:Jade is his grandmother - except it's an AlternateUniverse version of Jade. And Jake's counterpart in the original universe was Jade's grandfather... who was also her genetic father. And he's effectively cloned from Jade and her genetic brother, so his existence and parentage tells us nothing about Jade's future love life.]]
* In ''Webcomic/SoreThumbs'', Fairbanks' son had come from the future [[http://sorethumbs.keenspot.com/d/20110214.html in this strip.]]
* TimePolice officer [[spoiler: Philia]] from ''Webcomic/GastroPhobia'' turns out to be this for [[spoiler: Phobia and Klepto]]. When they break up and her father starts getting into a ShipTease with his childhood friend [[spoiler: Mania]], she agonizes over the possible TimeParadox. [[spoiler: Fellow time traveler Lord Nightsorrow decides to take Klepto's sperm cells with Phobia's egg cells, incubate them with magic, and allow the child to be adopted by Mania]], which everyone decides to accept.
* ''Webcomic/ArthurKingOfTimeAndSpace'':
** The space arc has a variation: Morgan has been brought forward in time to serve as Merlin's apprentice. While there, she and Arthur conceive a child, not realizing that they're [[BrotherSisterIncest half-siblings]]. When Merlin finds out, he returns Morgan to the past and she gives birth to Mordred... who in the present day is already serving aboard the ''Excalibur'' and doesn't know any of this. Also, Morgan met Squire Mordred while on the ''Excalibur'', and was so impressed by his ambition, she [[StableTimeLoop named her son after him]].
** A second, more straightforward example: Nimue, also a time traveler, brings Galahad from the future to meet Lancelot.
* In the comic ''[[http://transypoo.com/comic/ Transypoo!]]'' Acey's daughter from the future, [[http://transypoo.com/comic/?p=48 Jo Smit]], goes back in time, seemingly, to provide futuristic armor to the main cast, and possibly just to have fun.
* All known members of [[TimePolice TACT]] in ''Webcomic/LsEmpire'' are kids of members of the present cast. Hector is Rib and Bow's son, Pix is [[spoiler: Dark Star and Phala's son]] and Rosa is [[spoiler:Luigi and Daisy's daughter]]. Subverted in [[spoiler: Rosa's case. By the time she traveled back to the present, Daisy was already pregnant with her. And we don't find out that Dark Star and Phala are Pix's parents until after he's born.]]
* In [[http://nonadventures.com/2010/01/23/like-mother-like-slaughter/ this]] ''Webcomic/TheNonAdventuresOfWonderella'' comic strip, Dana's evil daughter comes from the future to kill Dana out of revenge for Dana always dismissing her and never letting her become Wonderella. Dana negates her daughter's entire existence by deciding to go back on birth control. (Of course, as Bianca points out, killing Dana now would have negated her existence anyway, but hey, kids are stupid.)
* Brady "Honey" Smith from ''Webcomic/SailorSun'' is a parody of this trope, and specifically Chibi-Usa.
* In the ''WesternAnimation/StarVsTheForcesOfEvil'' work ''Webcomic/ShipWarAU'', two kids from alternate futures arrive. Elizabeth, the daughter of Marco and Star, and Jam, the son of Marco and Jackie. They attempt to protect their parents and fight each other over getting their respective parents to come together, while on a mission to fix their timelines.

[[folder:Web Original]]
* Cassandra Cain from [[http://cass-cult.deviantart.com/ Cass Cult]] is on fairly good terms with the Legion of Cass Daughters, which includes her daughters from every possible timeline.
* In ''Podcast/RedPandaAdventures'', the Red Squirrel reveals in her first appearance that Kit Baxter, the Flying Squirrel, was her great-great-grandmother. It's not until the heroes' wedding day that she also confirms that the Red Panda was her great-great-grandfather, since she didn't want to affect the timeline by interfering in the WillTheyOrWontThey and the Red Panda himself was too polite to ask. When the Red Panda first sees the Red Squirrel's face, he's astonished by her resemblance to Kit. When Kit first sees her face, she's astonished at the Red Squirrel's resemblance to the Red Panda.
* In Roleplay/WeAreOurAvatars: A portal created by Damara Megido enabled the future kids to visit the past versions of their parents.

[[folder:Western Animation]]
* ''WesternAnimation/JusticeLeague'':
** Warhawk is ComicBook/GreenLantern (John Stewart) and Hawkgirl's Kid From The Future -- which came as a surprise because they had stopped dating quite some time before traveling to the future and running into him. This actually causes John to attempt a ScrewDestiny by not getting back together with Hawkgirl over the course of the series just so he doesn't feel [[YouCantFightFate pressured to do so]] just by Warhawk's existence. WordOfGod says that's okay, given that Warhawk is still only in his twenties by the ''Beyond'' time period, which is still a good forty years off.
** Technically there is two such cases in that episode, as a later episode tells us that [[spoiler: Terry [=McGinnis=] [[WesternAnimation/BatmanBeyond (Batman II)]] is Batman's biological son created by Amanda Waller.]]
* In ''WesternAnimation/TimeWarpTrio'', the original trio of Joe, Sam and Fred sometimes cross paths with their great-granddaughters from the future: Jodie, Samantha and Freddi.
* Jake becomes this in one episode of ''WesternAnimation/AmericanDragonJakeLong'' when he travels back to 1986 and accidentally causes his parents to split up. He then has to strive to get them back together in order to ensure his own birth.
* Destructicus, son of Hector and Dr. Ghastly, from ''WesternAnimation/EvilConCarne''. This raises questions on how this happened however as Hector is a brain (and stomach) in a Jar attached to a circus bear.... [[LampshadeHanging This is addressed.]] [[HandWave The given explanation is that]] [[ThePowerOfLove "love finds a way".]]
* ''WesternAnimation/DannyPhantom'':
** A unique case: the main character doesn't meet any future kids of his own--he meets a future child of his ''enemies!'' Box Lunch (daughter of the [[HarmlessVillain Box Ghost]] and [[MoodSwinger Lunch]] [[LethalChef Lady]]) who is sent by [[TimeMaster Clockwork]] to SetRightWhatOnceWentWrong. That is, killing Danny to prevent his [[FutureMeScaresMe future self]] from destroying the world.
** Danny himself does this when he travels back in time and prevents the accident that gave Vlad ghost powers. His mother ends up marrying Vlad instead, and they have no children. Danny has to convince her to help him fix things so he can go back to his own timeline.
* [[FragileSpeedster Bart Allen/Impulse]] in ''WesternAnimation/YoungJustice'' is [[ComicBook/TheFlash Barry Allen/The Flash]]'s grandson from the future. Coincidentally this occurred mere hours after Iris found out she was pregnant; she had not even had a chance to tell Barry yet. And ''she'' didn't realize she was having twins.
** Not so coincidental: [[spoiler:turns out Bart comes from a BadFuture, where Earth is a wasteland, and all the heroes are dead. Bart specifically went back to the day that Barry would have been killed, [[SetRightWhatOnceWentWrong as the first step of setting things right]]. Bart not only stops his grandfather's death, but [[BroughtDownToNormal takes away the powers]] of the guy who would've killed him (in the BadFuture, he become TheAtoner and helped Bart build the time machine)]].
-->'''Bart:''' [[RunningGag Oops! Spoilers]]...
* PlayedWith on ''WesternAnimation/PhineasAndFerb'', where they go to the future and meet their sister Candace's kids. We don't actually find out much about Phineas and Ferb themselves, including if either of them has children. Though it is implied that [[SiblingTriangle one]] [[TheUnreveal of them]] marries Isabella. In a few episodes, Candace mentions her dreams of one day marrying her crush, Jeremy, and having two children named Xavier and Amanda. Sure enough, those are two of the three future children, and while their father isn't revealed, Xavier looks an awful lot like Jeremy.
* In one HalloweenEpisode of ''WesternAnimation/TheSimpsons'', Bart travels back in time and meets Homer in high school, introducing himself as "the unwanted son from the future who kills all your fun." Homer starts strangling him at the very moment he first meets Marge, and she is so disgusted that she never marries him, and Bart becomes the son of Marge and Artie Ziff.
* ''WesternAnimation/CaptainPlanetAndThePlaneteers'':
** In one episode, some villains from the future travel to the present to [[MakeWrongWhatOnceWentRight assist the present villains]]. One of them addresses Dr. Blight as her ancestor. Dr. Blight says that can't be possible because she doesn't have any children and doesn't plan on having any. The woman glances significantly between Blight and Looten Plunder and chuckles, saying she will. Blight and Plunder get nervous and disgusted. It becomes a moot point because the changes done to the timeline end up causing the future villains to suffer a RetGone.
** In a different episode, Dr. Blight's daughter Betsi comes to the present. To everybody's shock, she is a good guy.
* In the ''WesternAnimation/PacManAndTheGhostlyAdventures'' episode "Pac To The Future", Pac-Man travels through time to when he was still a baby, and throughout the episode he has to keep his identity a secret from Pac-Man Sr. and Ms. Pac-Man while his friends work to bring him back to the present.
