History Main / TIMETRAVEL

* ''WebVideo/TheTimeGuys'' is built around this trope, having started as an AffectionateParody of {Back to the Future}.

* ''{{Voyagers}}'' - this was the entire premise. The 'Voyagers' were charged to SetRightWhatOnceWentWrong - they used one gadget, the ''Omni'' (which looked rather like a large gold pocketwatch), both to travel and to figure out what was wrong and how to set it right.
* ''KamenRiderKabuto'' heavily featured a [[MonsterOfTheWeek Worm]] ability called 'Clock-Up' (reproduced artificially by the Zecters used by the Riders) which allowed the user to [[TimeStandsStill warp the flow of time]] and [[SuperSpeed dramatically increase their speed]]. Later, Tendou gained the ability of Hyper Clock-Up, which allowed him to [[NewPowersAsThePlotDemands turn back time when the plot demanded]], but with the occasional habit of throwing him into nearby sub-dimensions. [[spoiler:Later still, one Worm could actually freeze time, strongly enough to even beat Hyper Clock-Up.]]

* The series ''{{Voyagers}}'' centered around a time traveler and a young boy who travel through time trying to fix things that went wrong in history.

* In Sean Ferrill's ''Literature/TheManinTheEmptySuit'', the narrator celebrates his subjective birthday every year by visiting a party 100 years after he was born. This, of course, means that every other version of himself is also in attendance. Temporal paradoxes are dealt with in an interesting way-- each version of himself is "tethered" to a younger version. When one of them creates a paradox, they become "untethered", having come from different timelines, but still existing on the same timeline. Confused? So is he.

* In ''TimeTrax'', the method varied, but the rules were that you could only travel between two set time periods (The Present and The Future), and more than two trips in a lifetime are lethal.

* ''Webcomic/TheAdventuresOfDrMcNinja''. [[http://drmcninja.com/page.php?pageNum=12&issue=14 Time-traveling Thomas Jefferson.]] [[ I don't really need to say it.]]

* This was a primary plot-point in season 3 of [[{{RedvsBlue}} Red vs Blue]]. During which Church is apparently blown into the past from the [[{{WhyAmITicking}} bomb that was placed in his gut]], while the rest of the members of Red and Blue teams were blown into the future. Church escapes the past by having the computer [[{{AIisacrapshoot}} Gary]] use his power to create a time machine so that he can go forward in time and stop any of this from ever happening.[[spoiler: It turns out that time travel never actually played a role in this though, and that all of Church's experiences in the past were actually him being tortured by Gary (who is really Wyoming's AI Gamma)and the others just being blown away by the blast. Though all of this wasn't put in place until it was [[{{retcon}} retconned]] by [[{{wordofgod}} Burnie Burns]] so that it fit with the later story lines of the Recollection and Project Freelancer.]]

* ''VideoGame/FinalFantasyXI'' uses this in ''Wings of The Goddess'' to travel 20 years ago to the Crystal War, one of the largest wars in Vana'deil's history.

* In ''WesternAnimation/TimeSquad'' the characters have to constantly go back in time in order to stop goofups in the timeline (because time is like a rope and as it grows it becomes frayed). HilarityEnsues when they encounter historical figures doing crazy things, such as Eli Whitney creating flesh-eating robots instead of the cotton gin, Ludwig von Beethoven becoming a wrestler instead of a composer, or [[GeorgeWBush]] thinking that the answer to all of the country's problems is a giant ball of twine.

* ''Series/{{Blackadder}} Back and Forth'' featured Blackadder and Baldrick traveling through time when Baldrick accidentally made a working time machine. Then they go back to SetRightWhatOnceWentWrong when they change history by accident. [[spoiler: Then they [[Set Wrong What Once Went Right MakeWrongWhatOnceWentRight]] so Blackadder could become king. For once, it ''worked''. ]]

* In ''Film/DonnieDarko'' people in the future will be able to mess with the past without leaving the future via machine. Such meddling causes alternate universes which need destroyed or they'll erase the future-people's universe.

* The sixth season of SonicForHire involves this. Sonic tries to go back to time with the [[ChronoTrigger Epoch]] to make sure he doesn't squander his life away. However, characters have been stealing his time machine and now many plotholes have occurred.

[[quoteright:240:http://static.tvtropes.org/pmwiki/pub/images/TimeTravel.jpg]]

* In FafnirTheDragon, the use of this to prevent a post apocalyptic future is what drives the plot of the first chapter.

* In ''{{Simoun}}'', time travel requires the successful completion of the Emerald Ri Maajon, an extremely dangerous maneuver that can only be accomplished by a pair of the most skillful pilots with [[TeamSpirit a powerful emotional bond]] with each other. Failed attempts are generally fatal, with [[NuclearWeaponsTaboo explosive consequences]].

* In ''UniversalWarOne'', scientists build a space station that accidentally opens a wormhole, allowing limited time travel. [[spoiler: Then Kalish solves the equations that allow anybody to travel through time and space without limitation.]]

* In ''DonnieDarko'' people in the future will be able to mess with the past without leaving the future via machine. Such meddling causes alternate universes which need destroyed or they'll erase the future-people's universe.

* In Jean Claude Van Damme's ''{{Timecop}}'', there's a federal agency responsible for going after people who attempt to go back in time. He winds up [[spoiler: having to go back in time himself to save his wife from dying, which is what he was hired to keep other people from doing.]]

* In TwelveMonkeys, James Cole travels to the past several times, to find a sample of TheVirus before it become ThePlague.
* In ''TheButterflyEffect'', the protagonist has mysterious periods of blacking out. As a young kid, he starts writing a journal describing his feelings. Years later, he finds out when he reads the journal before a blackout, he goes back in time to the period of the blackout. He quickly finds his time travel has a type of PsychicNosebleed limitation.

* ''{{Blackadder}} Back and Forth'' featured Blackadder and Baldrick traveling through time when Baldrick accidentally made a working time machine. Then they go back to SetRightWhatOnceWentWrong when they change history by accident. [[spoiler: Then they MadeWrongWhatOnceWasRight so Blackadder could become king. For once, it ''worked'']]

* In the card game ''{{Chrononauts}}'', the players are time travelers from various alternate futures, and are trying to change the timeline to match their own timeline's version of the "past" so that they can finally go home. Since all the alternate futures have conflicting versions of "history," and many of those conflicting versions require a specific outcome to World War II (Hitler was assassinated early and WW2 was Japan vs. America, Hitler lived and D-Day failed so that Germany won WW2, and a couple other variants), HitlersTimeTravelExemptionAct gets a real workout. There's an alternate victory condition in which players have to collect certain combinations of [[MacGuffin Mac Guffins]] of questionable historical importance, but that's for material gain, not timeline shenanigans. A third victory condition is to get hired by the local TimePolice after fixing enough of other people's paradoxes.

* In the "Timeline" mod series for the original ''HalfLife'', rogue scientists from Black Mesa have figured out how to use the dimensional portals to travel through time. Gordon Freeman is elisted to...

* ''{{Narbonic}}'': the 'Dave Davenport is Unstuck in Time' arc codified the rules, and future story arcs used the same rules. Fiddling around puts you in an Alternate Timeline. To move through time requires all the eneregy of an entire universe, thus ''utterly destroying an alternate universe/timeline'' in the process. Since you are in an Alternate Timeline, you can indeed change the future or the past. Dave is able to stop smoking by never having started. He is also able to give his past self information [[spoiler: that saves the lives of Helen and Artie, and avoids a BadFuture.]]

* In ''TimeSquad'' the characters have to constantly go back in time in order to stop goofups in the timeline (because time is like a rope and as it grows it becomes frayed). HilarityEnsues when they encounter historical figures doing crazy things, such as Eli Whitney creating flesh-eating robots instead of the cotton gin, Ludwig von Beethoven becoming a wrestler instead of a composer, or [[GeorgeWBush]] thinking that the answer to all of the country's problems is a giant ball of twine.

* In ''MiraiNikki'', its use is so incredibly spoileriffic details can't be given. Let's just say its important. [[spoiler: [[{{Yandere}} Yuno Gasai]] abuses THIS.]]

* ''SoukouNoStrain'' used the theory of general relativity to drive the plot. Sara's own motivations to become a Reasoner are to meet up with her brother, because if he returns from military service in space after a couple of years in his time, she'll be long dead in hers. Ralph's motivations are explained by his being able to go back hundreds of years using the same theory.
* The ''SuzumiyaHaruhi'' stories/anime feature time travelers, most notably [[{{Woobie}} Mikuru]]. It gets important in a major way in the novels, which also push Mikuru from being the NeutralFemale somewhat. [[spoiler: They travel to [[ArcWords 3 years ago]], and [[TrustPassword Kyon is the goddamn John Smith!]] ]] The 7th novel also circles around it, this time with a Mikuru from a week in the future, setting off events to inspire the future inventor of time-travel and set off events necessary to bring about her organization. Like by nailing a can to the ground to send a man to hospital so that he can meet his future wife, or by dropping a turtle into freezing water to teach the inventor of time-travel something.

* ''TsubasaReservoirChronicle'' later turns out to have used this, having hidden it among a bushel of jaunts to alternate universes, or "countries". One "country" turned out to be the main characters' homeland in the past. [[spoiler: And our world, or one much like it, in the future]].

* ''{{Zipang}}'', where a JMSDF destroyer somehow ends up at the Battle of Midway. It's actually much more interesting that it sounds.
* LetsLagoon where the fog surrounding the deserted island can cause things to travel through time.
* Its revealed in {{Eureka Seven Ao}} that Scub Coral uses time travel to transport parts of itself away to a different time and space to avoid the 1st series's calamity known as "Limit of Questions". It eventually lead to the existence of Secrets, the entire series major antagonists, and begins Ao and Generation Bleu's quest to stop Scub Bursts from happening. The 1st series hero and heroine, Renton and Eureka, are time travellers in Ao's world.

* ''PS238'', especially the later issues. Includes several confusing [[StableTimeLoop stable time loops]]

* Prior to [[PostCrisis 1985]] {{Superman}} could time travel under his own power but would arrive in the past completely invisible and intangible, unable to interact with the past in any way, avoiding the problems with this trope. After 1985, he was no longer powerful enough to time travel at all.

* ''PlanetOfTheApes''.
* ''{{Primer}}''.

* ''DragonridersOfPern'': The earlier books used the newly-(re)discovered time-traveling ability of the dragons for several plot points. After the Big One (Lessa bringing the lost Weyrs back thorugh time with her) time travel was relegated to a Save The Day plot device.

* The various protagonists of MichaelMoorcock's JerryCornelius stories time-travel more or less constantly - in fact with Jerry it's damn near involuntary.
** OswaldBastable is also subject to this kind of involuntary shifting between alternate histories.
* Literature/ThursdayNext features multiple versions of history within a single book, but only the reader and the (off-screen) timetravelers are aware of this fact.

* Toward the end of ''TheSecretsOfTheImmortalNicholasFlamel'', the conflict becomes less about stopping bad things from happening in the present and more about traveling to the past and ensuring that things happen the way they did.

* ''{{Kamen Rider Den-O}}'' features a superhero that travels back through time on a passenger train, [=DenLiner=]. Fairly early on, it is established that he is a "singularity point" a person who is completely immune to changes in the time stream and thus especially qualified to battle time-traveling Monsters of the Week. Why the OTHER singularity point handy, [[spoiler: Hana]], doesn't do the job remains unexplained.

* As the titles indicate, ''MiraiSentaiTimeranger'' and ''Series/PowerRangersTimeForce'' feature this; they're about TimePolice squads from the year 3000 who have chased a prisonful of escaped inmates to 2000 (''Timeranger'') / 2001 (''Time Force'').

* ''{{Achron}}'' takes the prime mention here - a RealTimeStrategy game whose plot ''and gameplay'' are both mostly about time travel.

* The ''EccoTheDolphin'' series is all about time travel. The second game's plot even centres around the time travelling in the first game screwing up the time stream.
* ''LegacyOfKain'': big part of the plot. Especially in ''Defiance'' where point of view jumps between two protagonists in different eras, culminating in them both travelling to the same era to finally meet.

* ''Franchise/PrinceOfPersia''. The Sands of Time trilogy features 6-10 seconds of time travel as the primary gameplay gimmick. The entire point of ''VideoGame/PrinceOfPersiaWarriorWithin'' is to SetRightWhatOnceWentWrong thus pushing your character's ResetButton. There's even a moment in ''VideoGame/PrinceOfPersiaTheTwoThrones'' wherein the prince decides not to use the reset button again and man up to his mistakes.

* ''[[WarriorsOrochi Warriors Orochi 3]]''. A monstrous eight-headed beast called the Hydra kills most of the heroes. The few remaining survivors are aided by Kaguya, the moon princess from ''Tale of the Bamboo Cutter'', who uses her ability to travel through time to rescue the heroes who died in the battle with the Hydra.
* ''SamAndMax'': Chariots of the Dogs
* ''SonicTheHedgehog'' '06 employed this trope annoyingly, to the degree that after a series of confusing time-jumps (one of which is to undo sonic dying), a small fire is blown out, thus erasing the whole sequence of events, time jumps and all. This renders it effectively an "It was all a dream" scenario.

* TimeTravel is used several times in the ''CommandAndConquerRedAlert'' series by various factions, trying to improve their fortunes (generally by removing key enemy figures, such as Hitler or Einstein). [[HitlersTimeTravelExemptionAct It never goes well]]; the first game kicks off when Hitler gets cut from history, leading to a WWII between the Allies and ''Stalin'', while in the third, the various time-travel shenanigans throughout the series have accidentally turned tiny backwater Japan into the Empire of the Rising Sun, a(nother) superpower bent on world domination. Hilariously, the Emperor believes in the "[[YouCantFightFate inevitability of destiny]]", and has a serious VillainousBreakdown when he discovers the truth behind the Empire's existence.

* The Android Saga from ''Manga/DragonBall Z'' is kicked off by the arrival of Trunks, a FutureBadass who owns both Frieza and King Cold when they come to Earth to seek revenge on Goku before revealing himself to be the son of Vegeta and Bulma. He's traveled back in time because the future he came from is a BadFuture where human civilization has been destroyed by the Androids and he wants to prevent that future from coming to pass by making sure that Goku doesn't die from the heart disease that he picked up on Planet Yadrat. He's only half successful because while Goku does survive the heart disease, he's out of action for the good part of the saga, leaving Trunks and the rest of the Z team to battle the Androids. Then an even more dangerous villain arrives from a ''third'' timeline...

* ''[[http://dig1000holes.wordpress.com/time-temp/ Time and Temp]]'' is another TabletopRPG entirely about TimeTravel, using office temps ([[DontExplainTheJoke temps, get it?]]) as field agents because (as [[{{Mooks}} unimportant shlubs]]) their lives are least likely to suffer a reality-ending paradox due to their own past actions. WhatCouldPossiblyGoWrong?

* ''VideoGame/NoOneHasToDie'' is a web-based PuzzleGame that is all about this.
