->''"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.

!!Examples

[[foldercontrol]]

[[folder: Anime and Manga ]]
* 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 due to his superior hearing) said anything.
* Chibi-Usa and Diana 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 ''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 ''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.
* The manga series ''Manga/LittleJumper'' 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.]]
* In ''TenchiMuyo [[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 ''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]]
* Nobita from ''{{Doraemon}}'' basically does Dane Cook's stand up joke from above in an early 90's 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.
* Suzune of ''KamichamaKarin'' came back to SetRightWhatOnceWentWrong and [[spoiler:prevent the eventual death of his father, though he doesn't know that part]].
* Aura of ''Mythic Quest'' 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 ''YomeiroChoice'' 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.
* In ''SteinsGate'' [[spoiler: Suzuha]] is this to [[spoiler: Daru]] although, neither know at first.
[[/folder]]

[[folder: Comic Books ]]
* Multiple instances with variation in the SummersFamilyTree of ''ComicBook/XMen'' fame.
** Rachel Summers (Phoenix/Marvel Girl) is this trope played absolutely straight: 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 ComicBook/XMen future Summers kids not tied to ''both'' of the above parents: ComicBook/{{Cyclops}} had a daughter with Emma Frost, in the form of Comicbook/{{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 MarvelUniverse, this has also happened in ''ComicBook/FantasticFour'' with Valeria [[spoiler:Von Doom]], daughter of [[spoiler:Sue Richards and DoctorDoom ([[{{Retcon}} or Reed Richards]], 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.
* Then, Hyperstorm came. Who is Hyperstorm? Child of [[FantasticFour Franklin Richards]] and [[XMen Rachel Summers]] 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!
** Valeria Richards made her first appearance as a time-traveling teenager before Sue became pregnant with her.
** For that matter, [[{{Comicbook/Avengers}} Kang The Conqueror]] always claimed to be a descendant of DoctorDoom. 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 [[SummersFamilyTree alternate-universe version of Nathaniel!]]
* Impulse, Bart Allen, was the ComicBook/TheFlash's cousin from the future -- and the grandson of Barry Allen, the greatest Flash of the DCUniverse.
** Also, Impulse's half-brother, Captain Boomerang Jr.
* Another case of the lead being the child is the current 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]]
* 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 (a possibly/possibly not) the parallel universe future AntiHero Thundra from a world where the male heroes of today are worshipped.
* 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?
[[/folder]]

[[folder: FanFic ]]
* 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.
* ''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
* [[http://s1.zetaboards.com/Danny_Phantom_World/topic/2638262/1/ This]] [[Anime/SailorMoon Sailor Moon R]]-esque WesternAnimation/DannyPhantom fan fic features Serena, [[spoiler:Danny and Sam]]'s future daughter.
* ''MyLittlePony Fanfic'' ''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 suposed to protecting Lily and instead gets 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 that this means Misaki won.

[[folder: Film ]]
* Wilbur Robinson from the film ''MeetTheRobinsons''. It wasn't really the ''plan'', but his actions do end up connecting Lewis with his family.
* In the movie ''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.
** And in the sequel, Marty travels back to 1955 again.
** And in the second sequel, Marty travels even further into the past and meets his ancestors, thus making him a Great-Great-Grandkid from the Future.
* Lampshaded in ''GuestFromTheFuture'' when Alisa jokes to Yulia "Maybe I'm your granddaughter."
* The 2011 film, ''Enter Nowhere'' [[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.]]
[[/folder]]

[[folder: Literature ]]
* Alba from ''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.
* 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'').
* In ''Bones of the Earth'', 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.
* This trope is central to [[http://chrisjonesbooks.com/the-glass-ruins/ The Glass Ruins]], where the main character is sent into the past [[spoiler:to prevent his mother who is pregnant with him from having an abortion.]]
[[/folder]]

[[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.
** 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.
** Clarification as to the original plan for Chris' origin: [[spoiler:Chris was supposed to be Phoebe and Cole's son from the future, that was supposed to give Phoebe a reason to have hope for her then unfortunate 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.]]
** In one episode, Future Chris' girlfriend Bianca shows up, and runs into her mother at one point.
* Alexander Rojenko does this in an episode of ''Series/StarTrekTheNextGeneration''. [[spoiler: Due to having grown up to be a pacifist and diplomat, his perceived weakness lead 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]].]]
** 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".
* 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'' features Kotaro, Ryotaro's grandson, who is also New Den-O.
* ''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.
* Claire Bennet plays this role in a season 3 episode of ''Series/{{Heroes}}'', as does Hiro Nakamura.
* 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 ''{{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.
* The ending of the last ep of ''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/DoctorWho'' had multiple examples, dealing with TimeTravel on a regular basis.
** River Song, first introduced to Tenth Doctor ''and'' killed off in 2008, turns out to be the daughter of Eleventh Doctor companions Amy and Rory, introduced in 2010. Her example is among the most extreme on this page -- thanks to the TimeyWimeyBall ''and'' [[TheNthDoctor Time Lord Regeneration]], she actually spends her entire teenage years growing alongside her parents as their contemporary BlackBestFriend, even playing a role in hooking them together. She also visited her parents' wedding and later married the Really700YearsOld Doctor herself, making her 20+something old parents his in-laws.
** An earlier episode, [[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!
** In the episode [[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.
** ''Series/TheSarahJaneAdventures'' episode "The Temptation of Sarah Jane Smith" uses [[RecycledScript the same plot]], incorporating both Kid and Grandkid from the Future.
* In the final season of ''Series/GoodnightSweetheart'', Gary (who regularly time-travels back to WorldWarTwo, and maintains a second life there) is taken aback to meet his Kid In The Present.
[[/folder]]

[[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]]

[[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 ''[[SpaceQuest Space Quest IV]]'', 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 ''Space Quest 6'', 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 ''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.
* ''InazumaEleven 3: the Orge'' features Endou Kanon, a kid from the future who try 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.
* {{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.]] After this reveal, when a male and female campaign character reach S support level, you can recruit their kid in a side chapter. There are a total of 13 future children; at least one of them will be [[PlayerCharacter yours]]. To make things even more ridiculous, your future kid can end up as the future kid of one of the other 12 future kids if you marry one of them.
* Petta from the PSP remake of ''VideoGame/MakaiKingdom'' is the daughter of Zetta (the Protagonist and self-proclaimed "[[{{Badass}} 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]].

* ''[[WalkyVerse It's Walky!]]'' has Bobby 'Machete' Walkerton[[http://www.walkypedia.com/index.php/Bobby_Walkerton]].
* In ''{{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 ''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 ''GeneralProtectionFault''.
* Vivio in the ''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]] [[http://img300.imageshack.us/img300/9425/nano105tryy0.jpg around]] [[HasTwoMommies with her mothers]].
* [[spoiler: John]] Taylor from CogaSuro, in a direct homage to [[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 J's counterpart in the original universe was Jade's grandfather... who was also her genetic father.]]
* In ''SoreThumbs'', Fairbanks' son had come from the future [[http://sorethumbs.keenspot.com/d/20110214.html in this strip.]]
* ''Webcomic/GastroPhobia'': [[spoiler:Philia]] is revealed to be this, and a member of the TimePolice, to boot.
* ''ArthurKingOfTimeAndSpace'''s 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 imprssed 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.

* Brady "Honey" Smith from ''SailorSun'' is a parody of this trope, and specifically Chibi-Usa.
* 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 ''RedPandaAdventures'', [[spoiler:The Red Squirrel]] reveals in her first appearance that [[spoiler: The Flying Squirrel]] was her great-grandmother, but it's not until later that she also confirms that [[spoiler:The Red Panda]] was her great-grandfather, since she didn't want to affect the timeline by interfering in the WillTheyOrWontThey.
* In Roleplay/WeAreOurAvatars: A portal created by Damara Megido enabled the future kids to visit the past versions of their parents.

[[folder: Western Animation ]]
* Warhawk in the animated version of ''WesternAnimation/JusticeLeague'' was 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.
** Technically there was 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.]]
*** These two are actually inversions, given that, as mentioned above, their parent came to ''them''. 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.
* In ''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 ''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 happned 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".]]
* A unique case in ''WesternAnimation/DannyPhantom''. 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 [[TheFlash Barry Allen/The Flash]]'s grandson from the future. Coincidentally this occurried 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.
-->'''Bart:''' [[RunningGag Oops! Spoilers]]...
* PlayedWith on ''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 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.
