7	Simply put, a StableTimeLoop where one is his own ancestor. Of course, this implies an IdenticalGrandson, and an [[TemporalParadox Ontological Paradox]] which results in a quarter of one's DNA being created from out of nowhere. It also requires an {{incest\|IsRelative}}uous coupling with another of one's ancestors, though the implications of this are seldom brought up.
8
9	The trope namer is not an example, however. The song ''[[https://www.youtube.com/watch?v=zeIsxXDyjlc I'm My Own Grandpa]]'' by Lonzo and Oscar in 1947 is about how the singer's character became his own ''step''-grandfather through [[TangledFamilyTree complicated marriages]]. This trope is about being one's own ''biological'' ancestor.

11	If they're just pretending to be their grandchild, then that's MyGrandsonMyself. See also KidFromTheFuture, for more time-travel and offspring-related hijinks, and TimeTravelRomance, which could also lead to this trope.

22	[[folder:Anime and Manga]]
23	* In the WhatIf movie ''Anime/DragonBallEpisodeOfBardock'', Bardock is sent back in time to start the legend of the Saiyans. It's probably better to be "My Own Progenitor", though it's physically impossible for Bardock to be the Super Saiyan Vegeta described unless the legend was ''really'' muddled.
24	* ''Manga/EdensZero'' has a twist of this trope with [[spoiler:Ziggy, Shiki's adopted grandfather, [[FutureSelfReveal revealed to be a future version of himself from a timeline where he was rebuilt as a robot]]. Ziggy's mission to reach Universe Zero with the ''Edens Zero'' and save Mother instead lead him to crash in the past and lose his memories. From there, he created the Four Shining Stars and found and adopted his younger self, an event that rippled across multiple timelines]].
25	* In ''Manga/{{Hinamatsuri}}'', the time-traveler Mao is implied to be a clone of herself.
26	* ''Manga/TsubasaReservoirChronicle'': Following clone Syaoran and clone Sakura's HeroicSacrifice, they re-incarnate in the past, meet, marry, and then become the parents of the original Syaoran. [[FridgeBrilliance This all makes a weird sort of sense]] when you take into account that the BigBad of the story has been making an attempt to rewrite the basic laws of reality, screwing up everything and causing things that should not make sense, or are flat out impossible to happen. When reality snaps back to normal, the original Syaoran becomes a walking paradox and is forced to continue [[FlyingDutchman wandering the multiverse]] as payment for his continued existence.
27	* Pierrot Bolneze in ''Manga/YakitateJapan'' was abandoned at a circus as an infant, but by Kazuma Azuma's history-changing Taima Ja-pan, he goes back to his childhood and ends up saving his mother from DeathByChildbirth. When Pierrot comes back to current time, both his parents are alive in this timeline. In this version of reality, he became a clown and was named Pierrot because his parents were so impressed with their old butler, the adult Pierrot from the future who was abandoned and raised in a circus.

30	[[folder:Comic Books]]
31	* Creator/AlanMoore's [[http://www.againwiththecomics.com/2007/11/forgotten-alan-moore-chronocops.html "Chronocops"]] strip for ''ComicBook/TwoThousandAD'' sees the [[TimePolice time cop]] narrator arresting his partner, who attempted to marry his own grandmother as a young woman after he suffered a mental breakdown. The narrator himself ends up retiring from the TimePolice after this and marries his partner's grandmother himself. His (now former) partner says that [[GrandfatherParadox he's going to kill him]] when he gets out of jail.
32	* ''ComicBook/DCOneMillion'' has the series antagonist Solaris, an evil artificial intelligence, sending a computer virus back to the 20th century, which is stopped by the Justice League by building a supercomputer to contain it, thus leading to the events that caused the rise of Solaris in the 853rd century in the first place.
33	* In the Year Three arc of the Tenth Doctor ''ComicBook/DoctorWhoTitan'' comics, it is strongly implied that the Doctor's contemporary-origin companion Cindy Wu is descended from one of the clones that the Paranestene created from her in ancient China.
34	* In a 1952 Creator/ECComics story "Why Papa Left Home" (published in ''Weird Science'' #11) a scientist invents a time machine and plans to test it by sending his assistant, Raymond 25 years to the past for two hours. However, due to an accident, Raymond ends up stranded in the past for two years. During this time, he falls in love with a woman, marries her, and they have a son (named Raymond Jr.). When he's brought back to the present, and meets his mother, he realizes that the child he fathered was himself.
35	* A bizarre example in Magazine/{{MAD}}'s ''ComicStrip/GasolineAlley'' parody, where the characters' disjointed [[NotAllowedToGrowUp aging rates]] eventually results in the protagonist's [[MindScrew wife turning into his daughter]], prompting him to exclaim the trope name.
36	* Played with, but averted, with the Creator/MarvelComics villains ComicBook/KangTheConqueror and ComicBook/DoctorDoom. Kang, the UrExample of the ConquerorFromTheFuture, was for some time believed to be a future version of Doom, and the two worked together (and double-crossed each other) on many occasions, culminating in the ''Secret Wars'' maxiseries, in which Doom had Kang disintegrated by [[DoAnythingRobot Ultron]] (he got better with the help of a RealityWarper). Later, however, it was revealed that Kang wasn't really Doom's future incarnation. He was actually either Mister Fantastic's father or distant cousin or some such thing ([[TangledFamilyTree it's confusing]]).
37	** What complicates it is that Reed Richards' father and Kang are ''both'' named Nathaniel Richards, but are completely separate people. We think.
38	** That can be explained by the Nathaniel Richards, who is Kang, is named in honor of the creator of the utopian society on Earth he originated from, Reed Richards' father: Nathaniel Richards...who is also a time-traveler.
39	** Kang is a bit of a mess. There is another character Immortus, more or less a good guy, who's a future version of Kang, and there turns out to be a rather large group of Kangs, from different points of their own timeline or from paralleled realities, that cooperate and occasionally congregate for various purposes, then there's a larger group of Kang-analogs that are clearly Kang but have different faces, different genders, different species... Eventually Kang is (much to his delight) able to change the timeline sufficiently that Immortus is the future self of an ''alternate'' Kang instead of the future self of ''him''.
40	** It is supposed to be impossible in the Marvel universe to become our own ancestor because you can't actually travel into your own past, unless you have 'Doomlock', a {{Magitek}} means of doing so invented by Doctor Doom. If you try without one, you end up in what will already become a different universe than the one you left (for example, ComicBook/RachelSummers tried to avert the future she came from, only to eventually find out she had arrived in a different timeline). This is a good thing, as overuse of the Doomlock leads to the TimeCrash of ''ComicBook/AgeOfUltron'' (the comic, not [[Film/AvengersAgeOfUltron the film]]) and is revisited as a problem in ''ComicBook/TheUltimates2015''.
41	* In ''ComicBook/XFactor'', the longstanding question of Comicbook/{{Shatterstar}}'s relationship with [[Characters/XMenMojoverse Longshot]] was finally resolved. Due to a mystical battle, Shatterstar got blasted back to his native dimension [[AnotherDimension Mojoworld]], but [[TimeTravel in the past]]. The Spineless One scientist Arize used genetic material taken from Shatterstar to create Longshot. At a relative future point in Mojoworld's timeline, Longshot will father a child with the human mutant ComicBook/{{Dazzler}}. This child will be [[HalfHumanHybrid Shatterstar]]. The infant will then be taken even further into the future, to be raised to become a gladiator and living a StableTimeLoop that includes his own involvement in the creation of his "father" and arranging his own upbringing. And we thought Cable and Rachel Summers had messed up origin stories!

44	[[folder:Fan Works]]
45	* The ''WesternAnimation/{{Futurama}}'' fanfic ''Fanfic/BlameItOnTheBrain'' makes greater use of the idea of Fry being his own grandfather. Not only does this give him an immunity to the Brainspawn due to his lack of a delta brainwave, but his self-manifestation [[spoiler:gives him a link to the fundamental fabric of the universe, much like the Nibblonians and the Brainspawn, who are essentially inverted versions of each other, although it is left unclear whether the Brainspawn manifested from the Nibblonians or the Nibblonians are the pre-flection of the Brainspawn]].
46	* Referenced in ''Fanfic/KyonBigDamnHero'', with Kyon recalling someone saying he looked identical to his grandfather at that age. Given how much time-traveling he does...
47	* At the end of ''Fanfic/LightAndDarkTheAdventuresOfDarkYagami'', it turns out that [[spoiler: Dark is actually his own ''father''.]]
48	* In ''Fanfic/MementoVivere'', a VideoGame/FinalFantasyX fanfiction, this question seems to rise when [[spoiler: Braska starts flirting with Rikku]]. Although technically they aren’t related by blood...
49	* Referenced but averted in "Mr. Bennet Travels Through Time", a ''Literature/PrideAndPrejudice'' fanfic in which the Bennet girls' father is a stranded time-traveler from the future. Shortly after becoming stranded he worries about the prospect of becoming his own ancestor, but in the event he only has daughters, so any Bennets in his own time must be descended from someone else.
50	* Averted in the ''Literature/{{Worm}}'' fanfic ''Fanfic/{{Recoil}}'' where, while a younger Danny Hebert does form a crush on his alt-daughter Taylor (''he'' doesn't know any better), she introduces him to his [[OneTruePairing future wife]] at the first opportunity. Also subverted, in that Danny's parents were trying to ''encourage'' the match.
51	* The ''Manga/RanmaOneHalf'' fanfic ''[[https://www.fanfiction.net/s/327129/1/Where-I-Came-From Where I Came From]]'' is basically ''All You Zombies'' applied to Ranma Saotome, with the reveal that he was both Genma and Nodoka. Genma came about when Nabiki got angry that Ranma and Genma were cured of their Jusenkyo curses thanks to a deal with Cologne, so Nabiki pulled a prank on a drunken Ranma and hypnotized him into believing he was Genma. The hypnotized Ramna uses the Nanban Mirror to go back in time and lives out Genma's life. As for Nodoka, she came out when Cologne thought Genma broke the deal, and so invoked the punishment of undoing the cure, locking him in his cursed form, and erasing any memory of being a male. As Genma was really Ranma, instead of turning to a panda, he was flung back in time, trapped in a body of a young girl with no memories, and given the name Nodoka by the authorities.
52	* A ''VideoGame/FireEmblemAwakening'' CrackFic called ''[[https://www.fanfiction.net/s/9198070/1/Ylissean-Bachelor Ylissean Bachelor]]'' has Lucina claim that she is her own mother. As Robin explains, [[InSpiteOfANail Chrom's first child will always be Lucina, regardless of who the mother is]], meaning that this could be made possible by the mechanics of their game. Luckily for Chrom, Sumia {{Megaton Punch}}es Lucina out of the studio before he's forced to follow through.

55	[[folder:Films -- Live-Action]]
56	* Spoofed in ''Film/{{Detention}}''. "Ione is pregnant with herself?"
57	* Caesar from the original ''Franchise/PlanetOfTheApes'' series was born when his parents traveled back in time, and he essentially became their distant ancestor as well as the forefather of the ape race.
58	* ''Film/PoorThings'' has a rare non-time travel example by way of mad science. Bella Baxter was created, Frankenstein-style, out of the intact body of a woman named Victoria Blessington, who committed suicide by jumping off a bridge, and the brain of Victoria's unborn baby daughter, who was still struggling to live as her mother's body died. The baby's brain was placed in the head of the body that used to be Victoria's, and it's that brain that matures into the Bella we know and love- making Bella her own mother.
59	* ''Film/{{Predestination}}'', the film based on the Heinlein story in the Literature section, except it takes the MindScrew a few steps further. Got a flow chart? [[spoiler: So the time agent is tracking a terrorist, and while doing so recruits a transman who turns out had sex with his female self, who then gave birth to him/herself. Said Time Agent takes the resulting baby to the orphanage to where said transperson was found, THEN is revealed not only to be a future version of the transman, but the terrorist he's tracking is a version of him even FURTHER down the line.]] No, don't worry, the headache will pass.
60	%% * Stanley sings the TropeNamer song in ''Film/TheStupids''.
61	* The title villain of ''Franchise/{{Terminator}}'' is the most famous western case, as its travels back in time resulted in it "fathering" its own master [=SkyNet=]. Technically, it could be said that it simply caused [=SkyNet=] to develop sooner rather than being the cause of its existence altogether.
62	** The [[Film/Terminator2JudgmentDay first sequel]] is a more straight-played example, with [=SkyNet=] being created by people who found a piece of one of [=SkyNet=]'s agents.
63	* ''Film/TimeriderTheAdventureOfLyleSwann'', where the hero went back in time and became his own great-grandfather.
64	[[/folder]]
65
66	[[folder:Literature]]
67	* In ''Literature/BookOfTheNewSun'', this is played completely straight, although never spoken plainly, where it is heavily implied that [[spoiler: Dorcas is Severian's Grandmother, and Severian is His Own Grandpa]], due to the ever-present time travel.
68	* The first edition of ''Literature/HarryPotterAndTheChamberOfSecrets'' has Dumbledore stating that Voldemort "is the last remaining ancestor of Salazar Slytherin". Of course, it was simply a mix-up with "descendant" on Creator/JKRowling's part. Some people use "ancestor" in a sense that includes "descendant", but it's best not to for clarity's sake, lest they fall into this trope.
69	** Some fans interpreted it as a clue that Time Travel would make a reappearance in the series, especially since Rowling referred to it as a [[IMeantToDoThat "deliberate mistake"]], but she was clearly being tongue-in-cheek.
70	* Spider Robinson's ''Have You Heard The One...'' features a visit to Literature/CallahansCrosstimeSaloon by a time-traveling salesman, whose plans are foiled by [[spoiler:Philip Jose Farmer's daughter Josie, who mentions that she "thinks she's going to grow up to be Mom."]]
71	* Creator/RobertAHeinlein loves this trope:
72	** [[ExaggeratedTrope Played to the extreme]] in the story ''Literature/AllYouZombies''. [[spoiler:The protagonist is a man who is ''both'' of his own parents. The story starts with him telling his backstory to a bartender: He was born female, and got pregnant after sleeping with a man. She gave birth via c-section, where it was discovered she was a {{hermaphrodite}} with internal male genitalia. Complications during the birth caused her to lose the function of her female genitalia so the doctors swapped them out for the still-functioning male genitalia, and she has been living as a man ever since. The bartender reveals himself as a time traveller working for a secret organization, and offers to take the protagonist back in time so he can save himself from that jerk who knocked him up and then disappeared. It is only after seducing and sleeping with his past female self that he realizes that ''he'' was the jerk. Meanwhile, the bartender travels nine months into the future to when the protagonist gives birth to herself, kidnaps the baby, and takes it further into the past to drop it off at an orphanage, thus completing the StableTimeLoop. Because ''the bartender is the protagonist too'', only older, and he wants to ensure his own creation. This twist is simultaneously {{foreshadow\|ing}}ed and {{lampshade\|Hanging}}d at the beginning of the story, when "I'm My Own Grandpa" starts playing on the jukebox in the bartender's bar, and the protagonist becomes angry and shuts it off]].
73	** ''Literature/ByHisBootstraps'' is an example by the same author of the "milder" version described above.
74	** ''Literature/TimeEnoughForLove'' has a blurb on the back cover that claims this trope occurs, but it couldn't have happened in the novel, nor could it have happened off-stage, since Lazarus's arrival date in the past was after his own birth, quite intentionally (and Maureen is already pregnant with a younger sibling of Lazarus when he arrives). The blurb-writer got a few other details of the book wrong, and probably was working from a grossly simplified synopsis.
75	* Parodied in ''Franchise/TheHitchhikersGuideToTheGalaxy''. Zaphod Beeblebrox's father is Zaphod Beeblebrox the Second, while his grandfather is Zaphod Beeblebrox the Third and his late great-grandfather is Zaphod Beeblebrox the Fourth. (Despite what one might think, there's no ancestral Beeblebrox numbered the Fifth or higher.) When asked why, he says it was "an accident [[NoodleImplements involving a contraceptive and a time machine]]". His great-grandfather, when summoned via séance, takes to referring to him as "Zaphod Beeblebrox the Nothingth" as an insult because of it. Though ''The Hitchhiker's Guide'' does state that becoming one's own grandparent through time travel is nothing that a significantly well-adjusted family can't deal with.
76	* ''Literature/TheInfected'' is not ''precisely'' this, but after a trip through time, Brian does wind up fathering one of his best friends, Scott.
77	* {{Downplayed}} in ''Literature/TheLicaniusTrilogy''. Davian isn't his own ancestor, but time travel does result in his saving his father's life and introducing his parents to each other.
78	* ''Literature/TheManWhoFoldedHimself'', [[spoiler:Dan is his own mother and father. How this is possible when time travel to the past forks into an alternate reality is unclear.]]
79	* In a book called ''The Mirror'', a young woman switches bodies/eras with her grandmother, and then lives her life (in other words, she is the one who has the great romance with the grandfather, who is thought by the family to be psychic, who gives birth to her mother...). [[TimeyWimeyBall At the beginning/end of the book]], she dies as her grandmother, while her grandmother then lives the rest of her life.
80	* Chuck Palahniuk's novel ''Literature/{{Rant}}'' - many of the major characters [[spoiler: repeatedly go back in time to become their father, grandfather, great-grandfather, etc.]] with the theory that [[spoiler: this eventually allows for an ascent into godhood via killing yourself since things without beginning have no end.]] Not only that, [[spoiler: the main character himself is his own [[strike: father]] [[strike: father and grandfather]]]]''[[spoiler: entire line of male ancestors.]]'' ''Lots'' of [[spoiler: time travel]] needed for that.
81	* ''Literature/TheStarDiaries'', "The Twenty-eighth Voyage": The private log of Cosimo Tichy, captain of a spaceship approaching the speed of light, mentions Cosimo's relative Amphotericus confiding to him that as a consequence of the latest temporal paradox (accelerating, the ship's stern had "cut across an isochronal"), Amphotericus is now his own father.
82	--> [A]pparently his time line knotted up into a loop.
83	* Creator/RobertSilverberg's time-travel novel ''Literature/UpTheLine'' has a character who is trying to sleep with all his female ancestors, except his mother (as he puts it, "I draw the line at abominations"). He's careful not to father any children, he is just seeking to cuckold all of his male ancestors (except his father because sleeping with his own mom would be sick).

86	[[folder:Live-Action TV]]
87	* Darla sired Liam, later known as Series/{{Angel}}, who in turn sired Drusilla. After getting staked early on ''Series/BuffyTheVampireSlayer'', Darla is resurrected as a human in the {{spinoff}} - but she still has the disease that was killing her before she became a vampire. As a last resort, Lindsey brings in Drusilla to vamp her. On having this "family tree" explained to him, Gunn has this to say:
88	--> "That means the granddaughter remade the grandmother. Man, somehow that weirds me out more than the whole bloodsucking thing."
89	* ''Series/Bodies2023'': Elias is born in the 21st century, travels back in time to [[spoiler:Victorian London to live as "Julian Harker", marries Polly, and starts a bloodline that culminates in Danny Barber conceiving him with Sarah Mannix]].
90	* ''Series/{{Charmed\|1998}}'': Piper Halliwell's past life, P. Baxter, was the great-grandmother of her present life. Points for being biologically possible, as the soul is the same, not the body.
91	* ''Series/Dark2017'' is a show that traffics heavily in bootstrap paradoxes as major plot drivers, though confined at first to the exchange of objects and information. In Season 1, the trope is only flirted with [[spoiler: by Mikkel returning to the past to become Jonas' father, though they were not originally relatives.]] However, Season 2 finally takes it all the way and reveals that [[spoiler: Charlotte's young daughter Elisabeth grows up and gives birth to Charlotte, who is kidnapped and taken to the past when she's still a baby. Thus both Elisabeth and Charlotte are their own grandmother, and each is both mother and daughter to the other]].
92	** In Season 3, it's revealed that [[spoiler: the child of Jonas and Martha from Eva's World later will give birth to Tronte from both universes, who will give birth to Ulrich, Mikkel, Magnus, Martha (from both worlds) and Jonas (from Adam's World) making all of them their own ancestors as well as descendants.]]
93	* In ''Series/TheFlipsideOfDominickHide'', Dominick, who comes from 2130, travels back in time to UsefulNotes/{{London}} in 1980 in hope of meeting the great-great grandfather he's heard so much about. It turns out to be a journey of self-discovery.
94	* Mentioned on ''Series/TheOfficeUS'' of all places, where Dwight claims that his ancestors were farmers, and before that, hunters, and before that, time travelers, and before that, Dwight himself again. Or at least that's how the legend goes. Based on some of the Schrute family's traditions, it's really not that far a stretch to think they really believe in that.
95	* ''Series/OrphanBlack'' has a weird variant without time travel, in which [[spoiler:the heroine Sarah turns out to be a clone of her adoptive mother's own mother]].
96	* ''Series/RedDwarf'''s Lister is his own ''father'', through time-travel shenanigans and other convoluted oddness.
97	* ''Series/RussianDoll'' offered an attempted variant in season 2. [[spoiler:Nadia time travelled to 1982, witnessed her own birth, and decided to take her newborn self back to 2022, thinking that for all the upbringing issues that made her such a screwed up person, no one would be better to raise the baby but herself - pointing out "being my own mother will bring me an aneurysm". Thus the same person twice in the future causes a TimeCrash.]]
98	* In an episode of ''Series/StarTrekDeepSpaceNine,'' Bashir wonders about this when he meets a woman on Kirk's ''Enterprise'' whose last name was that of an ancestor's, but it proved not to be true. PlayedForLaughs when Bashir argues that he must have sex with the woman after she invites him to her quarters, but Miles O'Brien refuses to let him be DistractedByTheSexy.
99	-->'''Bashir:''' I can't wait to get back to Deep Space Nine and see your face when you [[InsaneTrollLogic find out that I never existed!]]
100	:: Layered even further by Sisko insisting to the time police that there were no time paradoxes in play earlier in the episode.
101	* In ''Series/TerminatorTheSarahConnorChronicles'', the [=SkyNet=] example is taken even further, with the future AI going to great lengths to essentially create itself, since human time travelers are [[WellIntentionedExtremist quite willing to kill people who create SkyNet on their own]] in an effort to prevent Judgement Day. [[spoiler:Later it's revealed that some of the Terminators are from a rogue faction who are completely ambivalent to humans (though perfectly willing to kill individuals who present a threat to them) but very much opposed to [=SkyNet=], and have gone back in time to create their own anti-[=SkyNet=] AI that will go on to create ''them'' in the future.]]
102	* A RunningGag in the first season of {{WebVideo/Dimension20}}, ''Fantasy High'', is PC Gorgug's attempts at locating his biological father. In episode 7, "Graveyard of Good and Evil", he rolls a natural one on an insight check and for a moment considers the possibility that ''he could be his own dad.'' He is not.
103	--> '''GM:''' You're not proud of this. But you've been struggling with this for so long that momentarily, it occurs to you that there's a possibility, however slim, that you are your own dad.
104	[[/folder]]
105
106
107	[[folder:Video Games]]
108	* ''VideoGame/{{Achron}}'': The alien Grekim are able to pull this off in gameplay (see [[http://www.achrongame.com/forums/viewtopic.php?f=21&t=2903&hilit=Grekim+grandfather&start=20 here]] for directions how). It has [[AwesomeButImpractical little practical use]] though, so it doesn't happen often.
109	* ''VideoGame/DigimonTamersBraveTamer'' establishes that a combination of this and TimeyWimeyBall to MindScrew levels resulted in the birth of [[spoiler:Millenniumon: far in his future as [=ZeedMillenniumon=] he released Apocalymon, whose presence came to cause the existence of [[Anime/DigimonAdventure the Dark Masters]]. One of the Dark Masters was Mugendramon, who after his apparent death merged with a Chimeramon to form Millenniumon, who would go on to do horrible things, become [=ZeedMillenniumon=], et cetera.]]
110	** Add to that that Chimeramon was created by [[spoiler: Ken]] as a direct result of him [[spoiler:[[MoreThanMindControl having been hit by Milleniummon's dark spores]]]] years earlier. The irony being that [[spoiler: Ken]] ended up setting the events in motion that screwed up Ryo's life by TakingTheBullet for him.
111	* A variant shows up in the first ''VideoGame/EccoTheDolphin'' game. While Ecco is in the distant past, he can meet some proto-cetaceans who live on the land. Speaking to them gives them idea to try living in the sea. Thus, while Ecco isn't his own genetic ancestor (it's unlikely he'd have been able to breed with his evolutionary ancestors), he ''does'' accidentally set them on the path that leads to modern cetaceans.
112	* Caeldori from ''VideoGame/FireEmblemFates'' is an {{Expy}} of Cordelia from ''VideoGame/FireEmblemAwakening'', but several lines imply Cordelia is actually a reincarnation of Caeldori. Where this trope comes in is that, on the ''Revelation'' route, it's possible for Caeldori's mother to be Selena... who is Severa, Cordelia's daughter from ''Awakening''. Time-travel and world-hopping does weird things.
113	* ''VideoGame/OracleOfTao'' has a version of this that doesn't involve time travel, but rather a GodInHumanForm situation, where God impregnates her mother, even though God turns out to be her true form. [[HomosexualReproduction There are so]] [[ParentalIncest many things wrong]] [[TangledFamilyTree with this]].
114	* ''VideoGame/ShadowOfDestiny'': In this game, the protagonist Eike Kusch gains the ability to travel through time. In the second chapter, he meets up with a friend who owns a museum, Eckhart Brum, whose cat has just had a large litter of kittens. In a later chapter, Eike travels to 1902 and meets Eckhart's great-grandfather Alfred Brum. Alfred has a daughter named Sibylla (Eckart's great-aunt) who is lonely and Eike decides to give her a kitten. Eike returns to the present and then back to give Sibylla one of Eckhart's kittens which will inevitably become its own ancestor.

117	[[folder:Web Animation]]
118	* The ''Film/BackToTheFuture1'' example is parodied by ''Les Kassos'' in episode [[https://www.youtube.com/watch?v=Gt5-xU1-Ows #17]]. [[strike: Marty]] Darty goes back in time with [[strike: Doc]] Moc, and does [[ParentalIncest become his father.]] It's [[DeconstructedTrope deconstructed]] by giving him mental retardation, causing Moc to [[ScrewThisImOuttaHere leave him]] at the [[BeleagueredBureaucrat social worker's]] office. This all PlayedForLaughs.
119	* In ''WebAnimation/RedVsBlue'', Genkins refers to Chrovos as "grandpa" given [[GenderBender they]] created the two gods who in turn made him. Then once Genkins returns to the beginning of the universe, hoping to become more powerful like grandpa, he ''becomes'' Chrovos, including the part about being locked up by his children. Chrovos is surprised upon learning this, as [[TheFogOfAges they had forgotten this as eons passed.]]

122	[[folder:Webcomics]]
123	* ''Webcomic/DarthsAndDroids'' wrote many versions of the "LukeIAmYourFather" scene, with [[http://www.darthsanddroids.net/episodes/1191.html one rejected version]] following this trope.
124	-->'''Luke:''' [[BigNo Noooooooooooo!]] [[MoodWhiplash Also, why were you hitting yourself?]]
125	* ''Webcomic/{{Homestuck}}'':
126	** John, in the present, finds a cloning station which is locked on to four people: [[spoiler:his Nanna, Jade's Grandpa, Rose's Mom, and Dave's Bro]]. He clones all four of them, using paradox slime. [[spoiler:The slime from Nanna and Grandpa is mixed together, as is the slime from Mom and Bro. From the Grandpa/Grandma slime, clones of John and Jade are created, as are Rose and Dave from Mom/Bro slime]]. These clone babies [[spoiler:of himself and his friends are sent back in time, to become who they are now]]. Four "pure" clones babies are also created ... and [[spoiler:sent back to become Nanna, Grandpa, Mom and Bro]] in the first place.
127	** This also happened with [[spoiler:the trolls, with Karkat performing John's role. In this case, owing to the fact that troll parentage [[MemeticMutation sure is weird]], he also created the trolls' {{famous ancestor}}s, who are actually their decendants. The fact that he was the one who cloned them in the first place means that, by some definitions of parent, he is their collective father.]]
128	** In the [[spoiler:post-scratch universe]], the kids and their guardians [[spoiler: switch places, but presumably keep their old biology]]. It must be clarified that [[spoiler:while the kids and guardians are related in addition to John & Jade and Rose & Dave being sibling pairs, the guardians/post-scratch kids are not related to each other due to being true paradox clones]].
129	** The simplest way to describe the relationships between the players in Homestuck is that [[spoiler:everyone is everyone's grandparent.]]
130	* ''Webcomic/IrregularWebcomic'': Adam and Jamie from ''Series/MythBusters'' attempt to do this. They screw it up by accidentally sleeping with their counterpart's grandmother, becoming ''each other's'' grandfather, but incidentally it does make themselves their own ''great-great-grandfathers''. Which, incidentally ''does'' prove that this trope can happen, which was the whole reason they attempted this in the first place. Myth confirmed!
131	* Subverted in the very NSFW webcomic ''Webcomic/{{Oglaf}}'' when [[Theatre/OedipusRex Oedipus]] is convinced by his mother Jocasta to impregnate her ([[MindScrew and two other versions of Jocasta]]) with himself. It turns out that he kept his father's "equipment" and used it as a substitute.
132	* ''Wicked Powered'': Taken to its natural extreme. The main character was sent back in time twice (once [[GenderBender as a woman]] and once as a man). He arrived in the same time on both occasions. The two instances met, fell in love, got married, and conceived a child. Take a guess as to who this child was. [[spoiler: Oh. And the 'aunt' he was living with was actually his pet monkey.]] And apparently, being your own parents makes you immortal. Or something.

136	* In a Website/{{Cracked}} article, this turns out to be the case [[http://www.cracked.com/blog/grandmas-letters-to-her-mysterious-time-traveling-lover/?utm_source=newsletter&utm_medium=email&utm_campaign=newsletter-weekly-20160715 with a time traveler]].
137	* WebVideo/TheNostalgiaCritic describes ''WesternAnimation/TheThiefAndTheCobbler'' and ''WesternAnimation/{{Aladdin}}'' thus:
138	-->When I hear pop cultural references in a film that takes place in Arabia, I think of ''Aladdin''. But this was being made '''before''' ''Aladdin''. Apparently, Disney animators drew influence from this movie when it was being made that helped ''Aladdin'' get off the ground. And after that came out, the new producers of this film drew influence from ''Aladdin''. So ''Aladdin'' ripped off this, only to have this rip off ''Aladdin''. Basically, the film is a product of '''animated inbreeding'''. Suddenly, this is all starting to make more sense, isn't it?
139	* One of the members of the ''Website/SCPFoundation''’s O5 council, [[FourthWallObserver Joey Tamlin]], went 2000 years back in time and kickstarted his entire bloodline. This bloodline being [[BigScrewedUpFamily the Brights]].

143	* ''WesternAnimation/TheFairlyOddParents'' has an example. In the [[ShowWithinAShow Crash Nebula]] episode, Wanda says that there is an episode where Crash discovers he's his own great grandfather after traveling through time.
144	* ''WesternAnimation/FamilyGuy'':
145	** "[[Recap/FamilyGuyS9E16TheBigPangTheory The Big Bang Theory]]" has Stewie taking the place of his ancestor Creator/LeonardoDaVinci when he is killed by Bertram and managing to pass his own genes down before freezing himself and taking TheSlowPath back.
146	** "[[Recap/FamilyGuyS14E6PetersSister Peter's Sister]]" had a CutawayGag showing an alternate ending to ''Film/BackToTheFuture1'' wherein Marty figures that since he's about to [[RetGone fade into oblivion]], he might as well have sex with his mother in the past. The result is that in his picture of himself and his parents, they're replaced with an inbred Marty and the "To Be Continued" card is replaced with "To Be Contondered".
147	* ''WesternAnimation/{{Futurama}}'' provides a well-known example in its protagonist Fry, who unwittingly becomes his own grandfather. It's originally set up as the major plot point in "[[Recap/FuturamaS3E19RoswellThatEndsWell Roswell That Ends Well]]", in which Fry travels back in time to 1947 and encounters his grandfather Enos Fry. Fry becomes outrageously paranoid about Enos dying before he can have children, therefore causing [[RetGone Fry's own erasure from existence]], and so starts obsessively protecting him from anything even remotely dangerous... and in doing so ends up accidentally getting him killed. However, his death does not erase Fry from existence as expected, which greatly confuses him. Later, Enos's grieving girlfriend (Fry's grandmother) drunkenly propositions him. Fry reciprocates, deducing that his continued existence must mean that Enos wasn't really his grandfather, and therefore that this woman isn't really his grandmother. He's half right. While it seems like an interesting gag for that episode, it turns out to be a future plot point, as "the nasty in the past-y" (as they call it) causes differences to Fry's physiology that make him immune to certain forms of mind control. They even planned it from the start, providing a RewatchBonus a couple of times, especially once "[[Recap/FuturamaS4E10TheWhyOfFry The Why of Fry]]" reveals that [[spoiler:the Nibblonians deliberately engineered Fry's stint as a HumanPopsicle ''and'' his "past-nastification" so that he can use his mind-control resistance to defeat the Brainspawn and the Dark Ones]]. The experience also technically makes Fry's dad/son Yancy Fry Sr. ''his'' own grandpa, and the characters stop caring much about {{Temporal Paradox}}es after this point knowing what Fry was able to do with few ill effects:
148	-->'''Farnsworth:''' Let's just steal the damn dish and get back to our own time!\
149	'''Fry:''' But-- But won't that change history?\
150	'''Farnsworth:''' Oh, a lesson on not changing history from Mr. I'm-My-Own-Grandpa. Let's just get the hell out of here already! Screw history!
151	* At the end of ''WesternAnimation/TheGrimAdventuresOfBillyAndMandy'' episode "[[TheGrimAdventuresOfBillyAndMandyS4E3TestOfTimeAKickInTheAsgard Test of Time]]", after Billy and Mandy mess around with Grim's time manipulation remote, Billy ends up stranded at the dawn of man and falls in love with a cavewoman, resulting in him not only becoming his own ancestor but also the progenitor of all modern human ([[RuleOfFunny and animal]]) life on Earth. The last scene is of Billy waiting for the school bus like at the beginning, only now everyone else is as dumb as him and has his BlackBeadEyes and GagNose.
152	* In the ''WesternAnimation/IAmWeasel'' episode "My Friend, the Smart Banana", Weasel and the banana have an intellectual discussion and conclude that if you travel faster than the speed of light, you become your own grandmother.
153	* Brought up in a ''WesternAnimation/RobotChicken'' sketch where ''Film/TheForceAwakens'' is announced. Among all of the outlandish ways that it could potentially go wrong, one of them is a plot twist that Luke is his own father. This is accompanied by two Lukes having a lightsaber duel as one of them yells "I'll never join me!"
154	* In an episode of ''WesternAnimation/XiaolinShowdown'', Dojo warns Omi that by using the Sands of Time, "You can end up becoming your own grandpa." It can't actually happen, as time travel in this series operates on a "change the past you change the future" type deal.
