->''"There's this man. He has a time machine. Up and down history he goes, zip zip zip, getting into scrapes. Another thing he has is a passion for the works of Ludwig van Beethoven. And one day he thinks, 'What's the point of having a time machine if you don't get to meet your heroes?' So off he goes to 18th-century Germany. But he can't find Beethoven anywhere. No-one's heard of him, not even his family have any idea who the time traveller is talking about. Beethoven literally doesn't exist. [...] The time traveller panics, he can't bear the thought of a world without the music of Beethoven. Luckily he'd brought all his Beethoven sheet music for Ludwig to sign. So he copies out all the concertos and the symphonies, and ''he'' gets them published. He ''becomes'' Beethoven. And history continues with barely a feather ruffled."''
-->-- '''The Doctor''', ''Series/DoctorWho'', "[[Recap/DoctorWhoS35E4BeforeTheFlood Before the Flood]]"

You TimeTravel into the past; something happens as a result of your time travel, and [[ButterflyOfDoom somebody dies]]. Somebody important and probably even famous, who you ''know'' stayed alive until after this date. What can you do to close the StableTimeLoop, SetRightWhatOnceWentWrong, or at least [[TrickedOutTime trick out time]] so you can end up back in a CloseEnoughTimeline to your own? Why, impersonate them, of course!

Usually, for added [[RuleOfDrama drama]], the person you're replacing is supposed to die in some other way in order to trigger a significant event, meaning that you expect replacing them to lead to a HeroicSacrifice. This is not to say that it actually does, though; you can often find a [[TakeAThirdOption third option]] besides dying nobly in the past and screwing up the timeline.

There is also a variation in which the time traveller doesn't cause the historical figure's death, but instead -- as in the page quote -- discovers that the historical figure ''never actually existed''; the time traveller then has to impersonate the historical figure in order to [[StableTimeLoop create the history he remembers]]. This also makes the original historical figure an extreme ImpersonationExclusiveCharacter.

If the person was your own ancestor, this may turn into MyOwnGrampa, where you ''become'' your own ancestor.

Compare and contrast TimeTravelEscape; in particular, the third option in the more-dramatic version often involves pulling something like a TimeTravelEscape. Also compare BeethovenWasAnAlienSpy, which is a supertrope to at least the StableTimeLoop version of this, and EmergencyImpersonation, a very similar plot that doesn't require time travel.

[[folder:Audio Plays]]
* In the tremendously funny ''AudioPlay/BigFinishDoctorWho'' episode ''[[Recap/BigFinishDoctorWho081TheKingmaker The Kingmaker]]'', Creator/WilliamShakespeare manages to [[spoiler:get into a tiff with Richard III]] through a very complicated time travel mishap, ends up [[spoiler:on the Battle of Bosworth Field]] and promptly [[spoiler:gets mistaken for Richard III (very long story) and dies]]. Once the Doctor is past the initial shock, he wearily realises he's now got to [[spoiler:train Richard III in how to be Shakespeare]].
** In a much darker twist on the trope, the War Master uses an extremely dangerous variant in an attempt to take control of the Daleks by inserting himself into the Skaro scientific elite pre-"[[Recap/DoctorWhoS12E4GenesisOfTheDaleks Genesis of the Daleks]]" [[spoiler:by getting Davros killed, posing as his uncle "Sorvad", and taking his place as the Daleks' creator and master]] in the ''Anti-Genesis'' storyline.

[[folder:Anime and Manga]]
* One of the primary plot points in ''Literature/TheAmbitionOfOdaNobuna'', the main character--Yoshiharu Sagara--is deposited in the UsefulNotes/SengokuJidai without warning. Upon his arrival--in the middle of a battlefield--his life is saved by a young soldier, whose actions result in his own death. Asking the man's name, Yoshiharu is startled to discover the man is none other than UsefulNotes/ToyotomiHideyoshi. In the aftermath of the battle, he becomes a favorite of UsefulNotes/{{Oda|Nobunaga}} [[GenderFlip Nobuna]], and serves has her sandal-bearer, eventually taking Hideyoshi's place in this deviation of history altogether.
* ''Anime/BattleGirlsTimeParadox'' has a similar case to ''Nobuna'' above. OrdinaryHighSchoolStudent [[PunnyName Hide Yoshino]] ends up in another world, much resembling the UsefulNotes/SengokuJidai - except everyone in her textbook is a woman. She is found by UsefulNotes/OdaNobunaga and UsefulNotes/AkechiMitsuhide, introduces herself as Hideyoshi, and ends up taking [[UsefulNotes/ToyotomiHideyoshi that role]]. [[spoiler:Turns out her teacher Date-sensei is also in this world, and is currently masquerading as "hick samurai from Oshu" UsefulNotes/DateMasamune.]]
* ''Anime/NobunagaConcerto'' has high school student Saburou sent back in time and encountering a sickly Oda Nobunaga. When Nobunaga realizes how similar the two look, he asks Saburou to serve as his replacement [[spoiler:and later serves him as UsefulNotes/AkechiMitsuhide]]. An interesting depiction, as Saburou was not a particularly good student and only has a vague understanding of history, so the StableTimeLoop is more often than not one that occurs naturally rather than one he deliberately takes.
* ''Manga/KingOfWolves'' ends with the protagonist Iba [[spoiler:having no choice but to take on the identity of Genghis Khan after defeating the original one (who in this story turns out to have been Minamoto-no-Yoshitsune) who then committed suicide rather than live with defeat.]]
[[/folder]]

[[folder:Comic Books]]
* Applies to the ([[ComicBook/CrisisOnInfiniteEarths Pre-Crisis version of]]) Creator/DCComics' heroine Superwoman. She was a time traveling researcher who came to the present from the 29th century in order to try to find Superwoman's secret identity, the only superhero whose secrets were never discovered. She ends up realizing that ''she'' was supposed to be her. At first she only visited the past when recorded history said Superwoman appeared, but a time travel accident left her stuck there with amnesia for years. She eventually returned to her home time, however.
* This sort of happens in issue #5 of the original run on ''Comicbook/FantasticFour'', in which Dr. Doom (his first appearance) sends the foursome back in time and The Thing, who has always been a fan of stories of Blackbeard, ends up ''becoming'' Blackbeard.
* In the 1930s, ComicBook/AtomicRobo was a fan of pulp novels in general and [[TheWestern Western]]s in particular - notably, when Jack Tarot shows up, he's engrossed in the story of a bulletproof gunslinger called "Ironhide". When [[AchievementsInIgnorance Dr. Dinosaur]] sets off a [[RealityBreakingParadox "Time Bomb"]] in TheNewTens, he's blown all the way back to TheWildWest - and inadvertently becomes the real Ironhide's "successor", despite his best efforts to stay out of history's way.

* In ''[[https://www.fanfiction.net/s/10142174/1/Sword-of-Slytherin Sword of Slytherin]]'' Harry and Draco are accidentally sent to the past and end up pretending to be Hogwarts co-founders Salazar Slytherin and Godric Gryffindor, who were killed by bandits.
* Discussed in the ''Series/DoctorWho'' fic “[[https://www.whofic.com/viewstory.php?sid=8044 Fear and Freedom]]” when the Sixth Doctor finds himself in prison in a dystopian America in the mid-twenty-first century, where he's shocked to find Susan is also present. Talking with Susan, he learns that she was abducted from a cafe after a woman she was talking with was killed... and the Doctor recognises the name of the dead woman as the woman who was meant to organise the underground radio network that exposed the crimes of the current government and ended the current situation. The Doctor speculates that his younger self will deal with the change in history by arranging for his companion Barbara to take the place of the dead woman as the voice of the broadcasts, allowing the timeline to unfold as it should.
* ''Fanfic/AnEagleAmongLions'' sees Ashe Ubert [[spoiler:live out a prosperous, storied life as the legendary Pan the Tactician in the past]].
* In ''[[https://www.fanfiction.net/s/7180443/1/My-Mirror-Sword-and-Shield My Mirror, Sword, and Shield]]'', [[Anime/CodeGeass Suzaku]] accidentally travels back in time to the months before the assassination of Emperor Lelouch, gets to know him, and realizes he's actually the demon history makes him out to be... [[spoiler: and he ends up inverting this trope by replacing the assassin, saving the emperor, and bringing him back to the future with him.]]

[[folder:Literature]]
* ''Literature/{{Discworld}}'':
** In ''Literature/NightWatchDiscworld'', Vimes spends almost the entire novel impersonating his own mentor John Keel, murdered by the other half of the novel's TerminatorTwosome.
** In a non-TimeTravel example from ''Literature/{{Mort}}'', Mort and Ysabell learn that the Duke of Sto Helit was ''supposed'' to unify and bring peace to the Sto Plains after ascending to the throne via the murder of Queen Keli, an intended future which Mort screwed up by stopping the assassination. By the novel's end, the evil Duke is dead, and Keli appoints Mort as his replacement, obliging him to fulfill the villain's stabilizing role in history, albeit by diplomacy rather than subterfuge or conquest.
* Happens several times in the ''Literature/TimeWars'' series:
** In ''The Pimpernel Plot'', a time traveller's action causes the death of Sir Percy Blakeney, a.k.a. the Scarlet Pimpernel. One of the Time Commandos is assigned to replace Sir Percy to ensure that the events described in ''Literature/TheScarletPimpernel'' play out as they should. At the end of the mission, another agent is assigned to take over and live out the rest of Sir Percy's life.
** In ''The Zenda Vendetta'', the villains murder [[Literature/ThePrisonerOfZenda Rudolf Rassendyll]], again obliging one of the Time Commandos to take his place.
** In ''The Ivanhoe Gambit'', [[Literature/{{Ivanhoe}} Sir Wilfred of Ivanhoe]] isn't dead -- the heroes deliberately kidnap him so that one of their number can impersonate him as cover -- but the timing means that the impersonator does end up having to do all the stuff that Ivanhoe is remembered for (meanwhile, in a subplot, a supporting character becomes King UsefulNotes/RichardTheLionheart after the real Richard is killed by the villain).
** Perhaps because this imposes a restriction on the plotting, the other ''Time Wars'' novels just have the heroes befriending historical figures, not replacing them.
* In Creator/IsaacAsimov's ''Literature/TheEndOfEternity'', someone is sent back in time by the leaders of Eternity, a centuries-spanning time-traveling organization, to explain the workings of time travel to its purported inventor, thus completing a StableTimeLoop. The inventor dies, however, and the person from the future ends up replacing him and "inventing" time travel himself. Or rather, this was the plan of the leaders of Eternity, based on secret information about what had happened in the previous iteration of the loop, but in the end of the book [[spoiler:the StableTimeLoop gets broken, bringing about the eponymous "End of Eternity"]]. Probably the trope maker, and at minimum the trope codifier: pretty much every other example on this page traces back to Asimov and many directly allude to it.
* In Creator/TimPowers' ''Literature/TheAnubisGates'', the main character, expert in the study of a (fictional) Victorian poet, travels back in time and ends up being said poet in the past. This is the variant version mentioned in the description, as the poet in question didn't die and need replacing. He'd ''always been'' the time traveller, product of a StableTimeLoop with no discernible origin. [[TemporalParadox Nobody ever composed his poems, either]], which worries the protagonist more than the actual replacement does.
* ''Behold the Man'' by Creator/MichaelMoorcock. You can probably figure out the subject in question from the [[http://en.wikipedia.org/wiki/Ecce_Homo title]].
* In one of Creator/PoulAnderson's ''Literature/TimePatrol'' short stories, a time-traveler gets pressed into taking the place of an assassinated Persian royalty; history remembers him as Cyrus the Great.
** Another story in the same series, which has the magnificently awesome title "The Sorrow of Odin the Goth", has a time-travelling anthropologist trying to find the source of a particular legend involving the god Odin. He visits a dark-ages Goth community several times over the course of decades, and the locals, noting that he never seems to age (among other reasons), decide he is Odin. At the end he has to close the ''StableTimeLoop'' by doing what Odin is described as doing in the legend, even though it means killing two of his grandsons.
* The variety where the famous person never existed appears in at least two writings of Creator/StanislawLem.
* The protagonist of Creator/ManlyWadeWellman's ''Twice in Time'' travels back to Renaissance Florence to meet Creator/LeonardoDaVinci and to leave a mark on the back of the Mona Lisa to prove he made the trip. He eventually ''becomes'' Leonardo da Vinci and paints the Mona Lisa itself as proof of his trip. Of course, the time traveler's name was [[{{Foreshadowing}} Leonard]] to begin with.
* In ''Literature/{{The Missing|Haddix}}'' series by Creator/MargaretPetersonHaddix, this is combined with TimeTravelEscape. A group of children who are adopted, but cannot find their birth parents. They find out they are long lost children of the past (such as Anastasia or Virginia Dare of the Roanoake Colony) that were taken by time travelers from the distant future. Unfortunately, the time machine went wrong and ended up at an airport in the 90s. In the second book, ''Sent'', this trope is almost played straight when Chip and Alex are found to be missing medieval princes who are meant to be killed.
* In ''Literature/TheDoorIntoSummer'' by Creator/RobertAHeinlein, a professor who's invented a faulty form of time travel talks about how one of his students took the risk and went back in time. His name? [[Creator/LeonardoDaVinci Leonard Vincent]]. While he never appears in the story, so we never find out if he really is da Vinci, the protagonist wonders if Leonard, trapped in the past, drew plans for flying machines and such because he was hopelessly trying to recreate things he'd seen in the 20th century. He also quietly mourns for the man, talking about how incredibly impressively difficult it would have been for him to travel across fifteenth century, pre-Columbian America and wrangle his way to Europe, and pitying him as a FishOutOfTemporalWater either way.
** The protagonist himself fulfills the trope, [[spoiler: first by revolutionizing robotics and then, when he's betrayed by his business partner and fiancee and forced into suspended animation, uses the professor's time travel apparatus to return to the past with knowledge of future designs, set up a rival company, and drive his former partners out of business.]]
* ''[[http://www.gutenberg.org/catalog/world/readfile?fk_files=1563580 A Knyght Ther Was]]'' had Tom Mallory, a time thief. A particularly nasty rival sabotages his time machine, landing him in the 15th century -- when ''Le Morte d'Arthur'' was written (or compiled) by Sir Thomas Malory.
* In ''Literature/DirkGentlysHolisticDetectiveAgency'', it turns out that Music/JohannSebastianBach [[spoiler:never actually existed; Prof. Chronotis stole some unearthly beautiful music from a Salaxian space ship and used his time machine to plant it in the Baroque era under the pseudonym of Bach]].
* In ''Literature/InvadersOfTheRokujyouma'', Koutaro is cast in a play based on a legendary knight of Alien Princess Theiamillis' homeworld. Rehearsals include actual fencing lessons (Theia is a big fan of realism). On top of that, the only authentic costume was a full-body-interface PoweredArmor used to control her ship. When an attack by one of the princess' rivals ends up slinging both Koutarou and said rival a thousand years into the past to her homeworld, he ends up actually becoming the legendary knight.
* A very compacted version happens in ''Literature/HarryPotterAndThePrisonerOfAzkaban.'' Harry is swarmed by dementors and sees a figure he believes to be his dead father sending out a patronus to save him. Shortly afterward, Harry and Hermione travel a few hours back in time. Harry makes sure to hide out in the bushes near where the figure appeared so that he can have a chance to actually meet his father. When his father fails to materialize, Harry realizes he must have seen his own time traveling self (who is nearly [[IdenticalGrandson identical]] to his father), so he quickly steps out of the bushes and casts the patronus himself, just in time to be seen by his past self and set up (and close off) the StableTimeLoop.
* ''The Skull'' by Creator/PhilipKDick. An assassin is sent back in time to kill the founder of a subversive religion before he gives a famous speech, only to realize that the Founder is himself -- the 'miracle' that inspired the religion's creation was him appearing after he'd been killed (he'd arrived at the wrong point in time) thus 'coming back from the dead'. The RousingSpeech supposedly given by the Founder never actually happened, but was a result of history being embellished after his death.
* In "The Sword In The Stars", several of the Knights of the Round Table are missing from history. The main characters had to fill in for Sir Lancelot, Sir Lamarack, Sir Percival, and Queen Gweneivere upon time traveling.
* In the ''[[Literature/{{Dragonlance}} Dragonlance Legends]]'' trilogy, Raistlin Majere travels back in time to apprentice under the archmage Fistandantilus, [[spoiler:and ends up killing him and taking his place.]]
* This is a regular occurrence in ''Chorale'', a 1978 science fiction novel by Creator/BarryMalzberg. Based on a 22nd century [[MadScientist crackpot]]'s theories, science has accepted that the past and future are [[TimeyWimeyBall both extensions of the present]], and that the past must continually be reconstructed in order to exist. Thus, "travelers" routinely go into the past to impersonate great historical figures. Protagonist Reuter is, in fact, taking the place of Beethoven, despite the fact that he's not a musician and needs a rickety [[TranslatorMicrobes device]] to make his English speech sound German.
* In the ''Series/StarTrekDeepSpaceNine'' novel trilogy "Millennium", near the end of the second book, Vash and alternate future versions of Nog and Picard go back in time to ancient Bajor to become the seers "Eilin", "Shabren", and "Naradim", who are famous in the future because of their predictions of recent events.

!!!'''Series:'''
* A key plot point in ''Series/BabylonFive'' involves Sinclair going back in time one thousand years to intervene in the previous war against the Shadows [[spoiler: and become the Minbari cultural hero/religious figure Valen in the process]].
* ''Series/DoctorWho'':
** "[[Recap/DoctorWhoS3E3TheMythMakers The Myth Makers]]": Vicki decides to leave the TARDIS when she falls in love with Troilus, becoming the Cressida of Greek mythology.
** "[[Recap/DoctorWhoS26E1Battlefield Battlefield]]": The Seventh Doctor discovers that he will, in his own future, become Merlin in the King Arthur legends.
** The teaser to "[[Recap/DoctorWhoS35E4BeforeTheFlood Before the Flood]]" has the Twelfth Doctor [[BreakingTheFourthWall directly teach the audience about his trope]], although he's specifically using it as an example to teach about the Bootstrap Paradox — if Beethoven's work was copied out by a time traveller, who actually wrote the music? The Whoniverse being what it is, as the above examples show, he also has to clarify that it's hypothetical; Beethoven ''did'' exist, and the Doctor's met him. ("Nice chap. Very intense. Loved an arm wrestle.")
** "[[Recap/DoctorWhoS37E3Rosa Rosa]]: A racist time-travelling villain sabotages events to prevent [[UsefulNotes/CivilRightsMovement Rosa Parks]]' pivotal refusal to give up her seat on a segregated bus. Team TARDIS successfully get the bus and its driver back on course, but due to the saboteur, they need three more seats at the front of the bus filled by non-black passengers if Rosa is to be ordered to forfeit her place. With ''great'' reluctance, the Doctor, Graham and Yaz fill those seats, substituting for white passengers whom the saboteur had discouraged from boarding.
* ''Series/{{Farscape}}'': Aeryn tries this in "[[Recap/FarscapeS03E05DifferentDestinations ...Different Destinations]]" to save the life of a bumbling cook who clearly had no place in a battle. He doesn't let her, though, and dies like he's "supposed" to. Still doesn't fix the timeline, though...
* In the final season episode "Mokey Then and Now" of ''Series/FraggleRock'', Mokey, Wembley, and Boober accidentally [[TimeTravelEpisode get sent back in time]] after triggering some mysterious magic. They're sent back to a time in the distant past that Mokey identified as being before the arrival of a figure called the Great and Wondrous Blunding. It turns out that the Great and Wondrous Blunding was none other than Mokey Fraggle, who teaches the ancient Fraggles the "Dance Your Cares Away" song, promotes having hair, and encourages freedom over following a leader.
* In ''Series/{{Heroes}}'', Hiro goes to 17th century Japan to find that his childhood idol, Takezo Kensei, doesn't even come close to meeting his expectations. While not actually doing (some of) the amazing things that Kensei would be credited for, Hiro definitely plays a part in the making of history. In fact, the writers actually try and fake out the audience to think this is what Hiro is going to do after [[spoiler: Kensei dies]]. However [[spoiler: it is revealed shortly afterward that he is a "Special" and his wounds heal]].
* ''Series/LegendsOfTomorrow'':
** In "[[Recap/LegendsOfTomorrowS2E4Abominations Abominations]]", a Union messenger crucial to Ulysses Grant's victory in the Vicksburg campaign gets killed by zombies. So Jax has to take his place (and his name) to deliver a set of stolen battle plans to Grant.
** In "[[Recap/LegendsOfTomorrowS2E12Camelot3000 Camelot/3000]]", this trope occurs twice. First, the wizard Merlin turns out to be Stargirl. Then at the end of the episode, Queen Guinevere refers to Sara as "Sara Lance-a-lot", which sounds an awful lot like "Sir Lancelot".
* ''Series/TheMinistryOfTime'': Rogelio Buendía in episode 9. [[spoiler:After accidentally getting El Cid killed in 1079 while he filmed him fighting, he takes over his life, spending twenty years without seeing his family and playing someone he is not, even dying when the historical Cid did.]] Doubles as HeroicSacrifice.
** There is some FridgeBrilliance here in that Buendía is [[spoiler:a Francoist-era soldier (in fact, he was filming El Cid as documentation for the semi-propagandistic [[Film/ElCid 1961 film]] starring Creator/CharltonHeston) and the Cid he tries to live as is the legendary one that appears in the Medieval epics, rather than the purely historical one, because he knows no better. As a result, the legendary Cid ultimately arises from Buendía's own actions, rather than their supposed historical inspiration]].
* In the ''Series/RedDwarf'' episode "[[Recap/RedDwarfSeasonVIITikkaToRide Tikka to Ride]]", the crew go back in time and accidentally kill Lee Harvey Oswald, preventing the Kennedy assassination. After the usual time travel shenanigans (which include prompting Oswald to avoid being killed by them by inspiring him to move up to a different floor to take his shot), eventually they convince a JFK from later in the timeline to take the place of the assassin, [[WhoShotJFK firing from the grassy knoll]].
* ''Franchise/StarTrek'':
** In an [[WhatCouldHaveBeen early draft]] of the ''Series/StarTrekTheNextGeneration'' episode "[[Recap/StarTrekTheNextGenerationS3E15YesterdaysEnterprise Yesterday's Enterprise]]", Surak is accidentally killed by time-travelers, and Sarek has to take his place in order to bring logic to Vulcan. The actual episode is a borderline example. Tasha ends up going back in time with the ''Enterprise-C'' after she dies, but it's not to fool anyone into thinking she's anyone important -- it's just that they need somebody to manage tactical station on the ship.
** In the ''Series/StarTrekDeepSpaceNine'' two-parter "[[Recap/StarTrekDeepSpaceNineS03E11PastTensePartI Past]] [[Recap/StarTrekDeepSpaceNineS03E12PastTensePartII Tense]]", Sisko ends up in [[TwentyMinutesIntoTheFuture the 21st century]] as the result of a [[NegativeSpaceWedgie transporter accident]], where he has to impersonate the soon-to-be martyr Gabriel Bell after the real Bell is killed trying to help when Bashir is ambushed in a food line. At the end of the episode Starfleet Command has some questions to ask about why the picture of Gabriel Bell in the history books resembles him so closely; it gets {{lampshade|Hanging}}d again in a later episode when Nog is looking at a historical database and comments that Gabriel Bell looks an awful lot like Sisko.
** ''[[Series/StarTrekDeepSpaceNine Deep Space Nine]]'' also has a strange example with a short timeframe. In "[[Recap/StarTrekDeepSpaceNineS03E17Visionary Visionary]]", O'Brien is time-jumping uncontrollably, and he sees the station blow up in the future. To prevent this, he decides to force a time-jump, find out how the disaster happens, and come back. Unfortunately, the device that makes this possible emits deadly radiation, and O'Brien overestimates his endurance; when it's time to go back, he realizes he won't survive the return trip. Solution? He gives his future self the device and sends ''him'' back. The disaster is averted, and at the end of the day there's still just one O'Brien, but he can't help wondering if he's really the same man.
* A common element in ''Series/{{Timeless}}''. The premise is that a team of time travelers must prevent a rogue time traveler from rewriting history. Before they manage to foil the evil plan each episode, the bad guy has usually killed off an important historical figure or otherwise interfered with the historical event, so the team must undo the changes as best they can. When they return to the present, the new version of history incorporates their interventions, ranging from "Juliet Shakesman" having saved others from being assassinated the night Abraham Lincoln was killed to a mission they undertook with Creator/IanFleming inspiring a new ''Franchise/JamesBond'' novel and film.
* ''Series/TheTwilightZone1985'':
** In "[[Recap/TheTwilightZone1985S1E20 Profile in Silver]]", Professor Joseph Fitzgerald, a time traveler from 2172, travels back in time and ends up saving his FamousAncestor UsefulNotes/JohnFKennedy from the assassin's bullet. As a result, this creates an AlternateTimeline where the [[DepopulationBomb extinction of the human race]] via [[WorldWarIII nuclear war]] or other equally grim possibilities is inevitable. Kennedy is informed of this and offers to go back to be assassinated in order to restore the timeline, only for Fitzgerald to [[TimeTravelEscape send him to the future]] instead while he takes Kennedy's place in the limo and dies. In 2172, Kennedy gives a lecture at Harvard praising the sacrifice of heroes like Fitzgerald.
** In "[[Recap/TheTwilightZone1985S2E1 The Once and Future King]]", the ElvisImpersonator Gary Pitkin is sent back in time to Memphis, Tennessee on July 3, 1954 and meets the real Music/ElvisPresley, two days before he is due to perform "That's All Right" for Sam Phillips at Sun Records. The next day, Gary learns that Elvis intends to play "I Love You Because" instead and tries to convince him that he will ruin his chances of a record deal if he does so. However, Elvis begins to suspect that Gary has been sent to tempt him with devil's music and attacks him. In the ensuing fight, Elvis is [[InertialImpalement impaled on the neck of his guitar and dies]]. Gary then [[DeadPersonImpersonation assumes his identity]] and performs "That's All Right" for Phillips as history records Elvis did. It turns out that it was Gary posing as Elvis rather than the real Elvis who was destined to become the King of RockAndRoll. However, Gary wonders if Elvis would have made a better King if he had lived.
