History Main / TimeTravelEpisode

* "How Long is Forever?" from season 2 has the team fighting a time-traveling villain, Warp, and Starfire getting dragged two decades into the future in the process. Where her fears over her friends drifting apart actually happens when she enters a BadFuture where the Titans have disbanded.
* "Cyborg the Barbarian" has Cyborg being teleported to the Barbarian Ages, like the title states, three millennia ago. Where he befriends the leader of a barbarian tribe being attacked by giant insects and must contend with the tribe's treacherous second-in-command intending to usurp leadership.

* ''Machinima/Supermarioglitchy4sSuperMario64Bloopers'' has had four episodes:

%%* ''WesternAnimation/TransformersRescueBots'' The season 1 finale "It's a Bot Time"/"Bot to the Future". Zero-context example. What about these episodes makes them apply?

* From the ''Literature/StainlessSteelRat'' series, ''The Stainless Steel Rat Saves the World''. While time travel is mentioned in a few of the other novels in the series (e.g., ''The Stainless Steel Rat Wants You!'') it's central to the plot of ''The Stainless Steel Rat Saves the World'', which involves "Slippery Jim" diGriz traveling back into the past to prevent a hate-filled megalomaniacal time traveler from destroying the future civilization diGriz lives in by preventing it from having ever existed in the first place.

* In the ''Anime/PokémontheSeries:X&Y'' episode, Rotom's Wish!, after Ash and Company stumbles upon a hotel, a Rotom takes them to the past to help the hotel owner win a Pokémon battle against some unruly Pokémon trainers.

** ''Series/StarTrekTheOriginalSeries'': There's the episode "City On the Edge Of Forever", in which Bones accidentally steps through a time portal that takes him back to the 1930s, where he inadvertently changes the timeline so humans never went into space. It's up to Kirk and Spock to follow him and repair the damage.

* ''[[Series/BabylonFive Babylon 5]]'' takes this up a notch by having two time-travel episodes two years apart, which show the same event from two different perspectives. The first-season episode "[[Recap/BabylonFiveS01E20BabylonSquared Babylon Squared]]" gives us one point of view, and the third-season episode "[[Recap/BabylonFiveS03E16WarWithoutEndPart1 War Without End]]" gives another side. Be warned: Both are [[WhamEpisode Wham Episodes]], and better seen unspoiled.

* The ''WesternAnimation/MegaMan'' episode "Future Shock" was about Mega Man traveling to the future when he thought he'd sent Dr. Light there accidentally using a prototype time machine. But since Mega Man wasn't around to defeat Dr. Wily, he wound up in the BadFuture instead.

* In the ''WesternAnimation/ThePowerpuffGirls'' episode "Get Back Jojo", Mojo Jojo uses a time portal to travel back to 1959 and kill the young Professor Utonium so he can't create the Powerpuff Girls. The girls follow him and stop him, and witnessing all this turns out to be what inspired Utonium to become a scientist in the first place.

* ''Literature/GhostsOfFearStreet'' has ''Field of Screams'', where a boy is put into the body of a member of a baseball team in the 40's. A team that died in a tragic bus crash, so he has to find a way to prevent it.

** The appropriately named "That 70's Episode" featured the girls going back to before Phoebe was born to stop their mother from trading their powers to a warlock.

*** In "Future's End", the crew is sent back to the 1990's.

** Series/UltramanAce had the time-travelling monster, Daidarahoshi, which attacks Tokyo then uses its powers to flee when the TAC Defense Forces catches up with it. The TAC crew (including Seiji Hokuto, Ultraman Ace's host) manage to track down the monster, only to end up getting hauled a few thousand years into the past to Sengoku-era Japan with it where the crews' modern equipment and clothing got them into trouble with a local tribe. After destroying the monster, Ultraman Ace gives the TAC crew a lift with his own [[NewPowersAsThePlotDemands time-travelling powers which he displayed only once in this particular episode]].
** The Series/UltramanMebius kaiju Chronorm had the BossSubtitles '''Time Monster''', which is pretty much ExactlyWhatItSaysOnTheTin. Said kaiju uses its time-warping abilities to destroy civilizations by altering the memories of innocent people, and GUYS - alongside Ultraman Mebius - had to time-travel to the past in order to put an end to the monster's threats.

** ''The Andalite Chronicles'' is a borderline case, since it involves a TimeyWimeyBall, but they don't actually travel back in time.

** ''Megamorphs 3: Elfangor's Secret'' has the Animorphs chase a Controller through time as he tries to SetWrongWhatOnceWentRight.
** ''Megamorphs 4: Back to Before'' is an ItsAWonderfulPlot episode.

** [[Recap/GravityFallsS1E9TheTimeTravelersPig "The Time Traveler's Pig"]], when Dipper "borrows" a time-traveler's device in order to get a "do-over" after he beans his PrecociousCrush Wendy with a baseball.

This episode also carries the Aesop of "[[SomeAnvilsNeedToBeDropped You can't change the past, you can only learn from it]]".

While there, they meet Prince Valiant and help him to rescue his wife from an evil sorcerer. However, Ming's motive for sending his enemies back in time is far more nefarious than simply getting them out of the way; he has developed a [[TheSymbiote parasitic mutant life-form]] - and he has used the Defenders as pawns in his plan to send the organism back in time and destroy all life on Earth.

* ''WesternAnimation/SpongeBobSquarePants'': In "Back to the Past", [=SpongeBob=] and Patrick accidentally get sent back in time with Mermaid Man and Barnacle Boy, and Patrick foils their plan to capture Man Ray and stop him from taking over Bikini Bottom. When they go back in time to fix things, they need to stop Patrick from messing it up like the first time.
