1	->'''T'Pol''': Has it occurred to you what's going to happen if Captain Archer fails – if Earth is destroyed?\
2	'''Trip''': Every day.\
3	'''T'Pol''': Good. Then you've already come to the conclusion that, without humanity, there's no one to combat these Sphere-Builders. Their Expanse will continue to grow, encompassing one system after another, including Vulcan. Your world is no longer the only one in jeopardy.
4	-->-- ''Series/StarTrekEnterprise'', "Zero Hour"

6	Protagonists who need to SaveTheWorld in AnotherDimension often find [[RisingConflict their original dimension endangered as well]].
7
8	Maybe you're TrappedInAnotherWorld, fighting monsters and saving people so you can find your way home... and then you ''do''. Or maybe you've gone to another world after adventuring around your home, and found something a little too familiar about this place. Maybe you even go between worlds on a regular basis, and things are getting serious on the other side.
9
10	Either way, you discover the two worlds you've been flitting about in have a strange connection. It doesn't matter what it is, but it let you into the other world, and it can let something else out into yours. Generally it's monsters roaming the streets, but there can be other effects. Perhaps the BigBad is an EvilOverlord who has encountered your homeworld and has decided to forcefully add it to their domain. Perhaps the two worlds are threatening to collapse on each other. If the more mystical of the worlds is based in a computer realm, expect [[EverythingIsOnline a deadly effect on your hometown hospitals and roads]].
11
12	The other world's still in danger, but now so is ''yours'', and the {{Muggles}} certainly can't do anything about it. What do you do? You grab your adventuring party and a couple of friends from your homeworld, and you go out to save them both.
13
14	Contrast with UpTheRealRabbitHole or ExpendableAlternateUniverse, where both worlds are in jeopardy but the heroes don't see the one that isn't their own as real enough to merit saving. May overlap with TheCallKnowsWhereYouLive.

21	[[folder:Anime & Manga]]
22	* The various series of ''Franchise/{{Digimon}}'' often culminate in a threat that could destroy both the Human and Digital Worlds:
23	** ''Anime/DigimonAdventure'': Apocalymon [[SuicidalCosmicTemperTantrum spitefully attempts to self-destruct]] and create an explosion powerful enough to annihilate both worlds.
24	** ''Anime/DigimonTamers'' would've just been "save Earth", but the BigBad was directly tied into both worlds, and could only be defeated from Earth with help from both sides.
25	** ''Anime/DigimonFrontier'' had [[BigBad Lucemon]] attempting to go rampage on Earth after devastating most of the Digital World, but the heroes drag him back before he can actually make it there.
26	** ''Anime/DigimonDataSquad'' had the two worlds set to quite literally collide with each other. The FinalBoss King Drasil initially wanted to let this happen in a way that would destroy the Human World but leave the Digital World mostly intact; however, after enough setbacks and his minions turning on him, Drasil instead tries to force a mutual annihilation.
27	%%* Alchemist technology making it into our world is the plot of ''Anime/FullmetalAlchemistTheConquerorOfShamballa''.
28	%%* ''Manga/DragonDrive'': A video game leads to a virtual world that acts as a stepping stone to an alternate world. With Dragons.
29	* It turns out that ''Manga/ThoseWhoHuntElves'' need to get back to their home dimension to prevent it from fatally merging with the one they've found themselves stuck in. So their quest to get sent back becomes all the more important.
30	* In ''Manga/{{MAR}}'', Ginta's world and MÄR Heaven are connected largely by Snow's existence as a clone created from a fragment of Koyuki's soul. The Orb is also the manifestation of all the evil in Ginta's world as well. His plan was to use the connection between Snow and Koyuki to rip open a giant portal between the worlds to conquer Earth as well. In the end, Ginta ends up saving both worlds and Snow and Koyuki merge into a single person. Note this is only in the anime, in the manga the connection is different and the Orb's plan... doesn't make a whole lot of sense.
31	%%* ''Literature/{{Paprika}}'' has the protagonists trying to save both the real world and the DreamLand.
32	* ''Manga/PlanetLadder'' features a girl who discovers that there are nine dimensional Earths engaged in war and are moving towards collision with each other. She is [[SelfFulfillingProphecy prophesied]] to be the "Girl of Anansi" who can save only one of these worlds, but journeys among all the worlds to search for a way to save them all.
33	* Towards the end of the second series of ''Anime/SonicX'', the two worlds are revealed to be merging into each other again, with the catastrophic effect of canceling out each others timelines and causing time to come to a stand still. [[spoiler:The only solution is to send the Sonic characters home]].
34	* ''Manga/WatashiNoMessiahSama'' starts off with TrappedInAnotherWorld, with occasional visits back home. Then [[spoiler:monsters appear on Earth, and eventually Earth is threatened with destruction. Naturally, our heroes can't save just one of the worlds]].
35	%% * Anime/PrettyCure has this in every series. %% It might be a good idea to name specific examples, just to be sure this isn't a zero-context example.
36	* In ''Anime/TamagotchiHappiestStoryInTheUniverse'', Kikitchi staying in one of the Flying Library's {{Portal Book}}s has an effect on Tamagotchi Planet due to a page in the book being missing, causing the story within to loop endlessly. As a result, Tamagotchi Planet is at risk of being turned into paper on top of the book becoming unstable, and Mametchi and co. have to save both of these worlds.

39	[[folder:Comic Books]]
40	* Almost subverted in the third issue of the ''ComicBook/JLAAvengers'' crossover miniseries, both groups of heroes are unsure they want to restore their universes when they witness the {{Face Heel Turn}}s, {{Heroic Sacrifice}}s, {{Suspiciously Similar Substitute}}s, and WithGreatPowerComesGreatInsanity that they will experience in the "correct" universe. Out of everyone Franchise/GreenLantern Hal Jordan, who has the most to lose, argues they don't have the right to play God with the two universes, causing the heroes agree to restore reality.
41	* ZigZagged in ''ComicBook/DoomsdayClock''. [[spoiler:After the {{narcissist}}ic KnightTemplar Ozymandias' UtopiaJustifiesTheMeans [[EvilPlan plot]] failed [[Comicbook/{{Watchmen}} in his own universe]] and he ends up in the ComicBook/DCRebirth universe, he comes up with a plan to "save" both worlds by deliberately engineering yet another DarkestHour for the DC heroes as part of a BatmanGambit to get ComicBook/{{Superman}} and [[PhysicalGod Dr. Manhattan]] to fix everything. It works, but whether it was because of or in spite of him is hard to say.]]
42	* In Franchise/WonderWoman storyline "[[ComicBook/WonderWoman1942 Judgment in Infinity]]", a group of heroines come together to save five parallel Earths from the [[EldritchAbomination Adjudicator]].
43	* Initially, the end goal of the heroes of ''ComicBook/InfinityWars'' was to undo Gamora's merging of half the universe, but things take a turn in the fifth issue of the main story, in which [[ComicBook/Warlock1967 Adam Warlock]] informs the [[ComicBook/CaptainAmerica Soldier]] [[ComicBook/DoctorStrange Supreme]] about the heroes' intentions, and the Soldier Supreme protests in response, refusing to give up his life for the sake of bringing back Dr. Strange and Captain America as two distinct beings again. The goal from that point forward, then, is to restore the regular Marvel Universe while preserving the Warped Universe within the Soul Stone.

45
46	[[folder:Fan Works]]
47	* ''Fanfic/TheCaptainOfTheVirtualConsole'' has this as its plot. Gancena must save the video game worlds and her own.
48	* In ''Roleplay/WeAreAllPokemonTrainers'', when given the choice, the J-Team decides to have Dialga and Palkia fork the AU inadvertently created by Cyrus into its own separate universe, despite the fact that it replaced their original universe, because they deemed it to have just as valid an existence.
49	* Taken to the extreme in ''Fanfic/InfinityCrisis'', as a comparatively small group of heroes plan to save the entire Multiverse.
50	[[/folder]]
51
52	[[folder:Films - Animated]]
53	* In ''WesternAnimation/BarbieAndTheSecretDoor'', the heroines must save the magic of all realms of Zinnia.
54	* In the fourth ''Animation/PleasantGoatAndBigBigWolf'' film, ''Animation/MissionIncredibleAdventuresOnTheDragonsTrail'', the goats learn that dragons are responsible for [[PaintingTheFrostOnWindows making the clouds, stabilizing the soil, and holding the trees up from underground in the Green Green Grassland]] and that the destruction in the Dragon World is making them panic, affecting the Grassland. Thus, they have to save the Dragon World if they want to save the Grassland.
55	* In ''Westernanimation/MyLittlePonyEquestriaGirls1'', Twilight Sparkle goes to a HighSchoolAU featuring human counterparts to her friends and most of the show's cast. While her main objective is to retrieve her crown where her Element resides from BigBad Sunset Shimmer, she also quickly makes a friendship with her counterparts. This becomes a plot point when at the film's climax, Sunset threatens to destroy the portal connecting the two worlds if she didn't give her the crown. Twilight reasons she'd stay to help them, even if they'd both be doomed to never return to Equestria, since Sunset would be free to hurt her friends either way. Her bond with her new friends is strong enough to summon the Elements of Harmony and defeat her OneWingedAngel form. Only when she ensures that her friends would try to show Sunset Shimmer kindness after stripping her of power, does she cross back to Equestria. Nor does she forget this world after leaving, coming back in [[WesternAnimation/MyLittlePonyEquestriaGirlsRainbowRocks the next movie]] to help her human friends and [[TheAtoner a reformed Sunset Shimmer]] confront the next magical threat. Sunset, despite being from Equestria like Twilight, never shows any inclination to return after her HeelFaceTurn and [[IChooseToStay makes the human world her home]], defending it from magical threats. The series then continues on for more entries that don't involve the main series characters at all.

57
58	[[folder:Films - Live-Action]]
59	* The second half of ''Film/LastActionHero'' has Danny returning to the real world and bringing fictional action movie hero Jack Slater with him. Unfortunately, [[spoiler:Benedict is there as well, and he's got the ticket to travel between movies and the real world to bring through anything he wants.]]
60	* Sort of done in ''Film/MirrorMask''. By saving the dreamworld, Helena also saves, symbolically, at the very least, her mother's life, and stops "her world" from being shattered. It's not as {{Narm}}y as it sounds.
61	[[/folder]]
62
63	[[folder:Literature]]
64	* Technically, the titular heroine from ''May Bird'' series has to save "only" the ''Ever After'' world, but since all humans (including herself) will inevitably go there after death, this affect everybody on Earth as well. And [[spoiler:the BigBad is actively interfering with Earth, too, and it's only a question of time when he wrecks the Earth directly.]]
65	* ''Literature/TheMagiciansNephew'', when Diggory lets Jadis loose in London and then in Narnia.
66	%%* ''Literature/HisDarkMaterials'', not just worlds that Will and Lyra come from, but the entire multiverse.
67	* The ''Literature/ApprenticeAdept'' series; Stile is a native of science-based Proton, but is brought to magical Phaze as part of a GambitRoulette to correct an imbalance that would destroy both worlds.
68	* In Creator/AaronAllston's ''Literature/DocSidhe'', the protagonist is transported from the "grim world" (ours) to the "fair world" (Faerie), where he discovers a plot to subvert the connection between the worlds, threatening both. Both worlds are again threatened in the sequel, ''Sidhe-Devil''.
69	* In the ''Literature/{{Everworld}}'' books, it would be a bad thing if the gods crossed over into the world of our own, or if aggressive human men with guns crossed over into the world of Everworld. Both of these dangers threaten to happen over the course of the stories.
70	* In ''Literature/KeysToTheKingdom'', Arthur has to deal with threats in both the House and on Earth, particularly since if the House falls, so does the rest of the Universe.
71	* Mark Anthony's ''Literature/TheLastRune'' series, which features characters spending time in, and crossing between, Earth and the otherworld of Eldh. These include multiple villains and world-threatening dangers.
72	%%* Extremely weird example in Creator/ChinaMieville's novel ''Literature/TheCityAndTheCity''.
73	* ''Literature/{{Coraline}}'', where the titular heroine must beat the Other Mother [[spoiler:to save her parents and stop Other Mother from kidnapping children]].
74	* Creator/StephenKing's ''Literature/TheTalisman'' sees Jack flipping between our world and the 'The Territories' in an attempt to save his Mother from dying, this also has the side affect of saving the Queen in The Territories as they share a magical link.
75	* ''Franchise/TheDarkTower'', although in this there are many worlds and Roland and his companions must save all of them (since they will all be destroyed if the Dark Tower falls). However, Roland's world and Earth are the main ones that the heroes focus on.
76	* Much of ''[[Literature/YoungWizards So You Want To Be A Wizard]]'' by Creator/DianeDuane is spent in an alternate universe where the [[BigBad Lone Power]] has already put out the sun. At the climax, the protagonists make it back into their own universe, but the Lone Power follows them through the worldgate and they have to stop it...
77	* The AffablyEvil villain in ''Literature/{{Everlost}}'' is trying to kill everyone and destroy everything in the real world so it will all be "preserved" in Everlost.
78	* In ''Literature/DeepSecret'', the protagonists from Earth get involved in a succession crisis in the Koryfonic Empire, which spans several alternate universes. If the villains are successful, there will be bad consequences for universes beyond the Empire, including Earth's.
79	[[/folder]]
80
81	[[folder:Live Action TV]]
82	* The third season of ''Series/StarTrekEnterprise'' somewhat inverts this. Since Starfleet is fairly new to the galactic stage, their conflict with the aggressor Xindi is largely ignored by the galaxy at large, including their Vulcan "allies". As the story unfolds, however, it becomes clear that the Xindi are just {{Unwitting Pawn}}s of the Sphere-Builders, AbusivePrecursors who plan to invade and [[HostileTerraforming transform]] the galaxy into something more hospitable to their kind, which will doom all sapient life -- human, Xindi, Vulcan, and other -- to extinction. This revelation causes a schism within the Xindi, most of whom flock to humanity's side against their former-deities, and the Andorians also show up to help at the end.
83	* In ''Series/MythQuest'', there is a god named Gorgos who lives to change and destroy mythology. He escapes into an advanced computer system where he has the power to alter the outcome of the myths. Minor changes only seem to cause a ripple effect in global knowledge of the myth, but when he tricked a character into almost causing Ragnarok, a large earthquake was felt in the real world.
84	* ''Series/TheFamousJettJackson'': Referenced in TheMovie:
85	-->'''Silverstone''': If Kragg gets this world, it's only a matter of time until he comes for yours.
86	* The cornerstone of ''{{Series/Fringe}}'' and its mythology is an AlternateUniverse, and the protagonists of the show (from the prime universe) are using MadScience in an attempt to save both worlds after the first attempt at crossing from one universe to another resulted in a parade of soft spots, cracks in the walls of reality, breakdowns of the laws of physics, [[SwirlyEnergyThingy swirly energy thingies]], [[NegativeSpaceWedgie negative earth wedgies]], [[Film/{{Ghostbusters 1984}} dogs and cats living together]], etc. that threaten to destroy both universes. This is juxtaposed by the characters from the AlternateUniverse, who believe the only way to save their universe is to destroy the prime one first (and they may be right). [[spoiler:Or not, as it is revealed that the two worlds are permanently intertwined; therefore, the only way for any character to save their world is to save both of them.]]
87	* ''Series/MiraiSentaiTimeranger'' has what could be called a "Save Both ''Times''" variant towards the end. [[spoiler:Captain Ryuuya reveals that there were two possible timelines leading to his current time, with a cataclysm happening either in the 21st or 31st century, but both of them had something in common: he himself would die as [=TimeFire=]. His plan in sending the Timerangers to the past was to ensure that the cataclysm would happen in the 21st century and have someone else die in his stead, and then wipe their memories to cover his tracks. The Timerangers however chose to go back and save the past as well, with the implication that in doing so they also saved the future]].
88	[[/folder]]
89
90	[[folder:Video Games]]
91	* ''VideoGame/ArcanaHeart'': An angel with a [[AGodAmI God complex]] is trying to break down the barrier between the real world and the Elemental world. She ''almost'' succeeds.
92	* In ''VideoGame/DigimonSurvive'', the cast is [[TrappedInAnotherWorld trapped in the Digital World]] and spend most of the game desperately seeking a way back. [[spoiler:They later learn that the BigBad is an EldritchAbomination seeking to take over the Digital World and [[KillAllHumans destroy the human world]], forcing them to deal with it first before they can return.]]
93	* ''Franchise/SonicTheHedgehog'':
94	** In ''VideoGame/SonicRush'' Blaze is trapped on Sonic's world with the Sol Emeralds. If the Sol Emeralds aren't returned, both worlds will be destroyed.
95	** In ''VideoGame/SonicRushAdventure'', [[spoiler:Sonic and Tails discover they are trapped in Blaze's world. Eggman and Eggman NEGA team up at the end of the game to steal the Jeweled Scepter, which keeps the two worlds separated]].
96	* ''VideoGame/{{Outcast}}'': Opening the portal between the two worlds creates a black hole which will swallow up the Earth... unless you enter the alternate universe to figure out how to stop it. It turns out the alternate universe needs to be saved as well.
97	%%* ''VideoGame/FinalFantasyV'', although it's really more [[spoiler:combine both worlds and ''then'' save them.]]
98	* ''VideoGame/AnotherCenturysEpisode 3'' features a "save both worlds" plot, as some AppliedPhlebotinum that exists in both worlds creates a dimensional rift, pulling the two Earths together due to gravitational forces. Also connects to ''Eureka 7'' pretty significantly, since it's an IntercontinuityCrossover.
99	%%* ''Sudeki''. Much like the ''Final Fantasy V'' example, [[spoiler:both worlds get combined and you have to save them.]]
100	* ''VideoGame/TalesOfSymphonia'' soon becomes this type. [[spoiler:The BigBad's EvilPlan alternates which world is in trouble but]] both ultimately have to be saved for either to have lasting peace.
101	%%** Also shows up in ''VideoGame/TalesOfEternia'', as an intended result of a YinYangBomb.
102	%%* This seems the backbone of ''VideoGame/MarvelVsCapcom3'', in which all characters fight in scenerios from both Marvel-Earth and Capcom-Earth.
103	* In ''VideoGame/MortalKombatVsDCUniverse'', the simultaneous defeat of Shao Kahn and Darkseid has caused the worlds of ''Mortal Kombat'' and the DC comics to begin to merge, with potentially dire results if not undone. The kombat fought between the denizens of both universes also serves to accelerate the process. [[spoiler:It's not until Superman and Raiden overcome their differences that they can overcome Dark Kahn's influence and save their worlds.]]
104	* ''VideoGame/TheLegendOfZeldaALinkBetweenWorlds'': Link starts out trying to save Hyrule, but soon finds that its counterpart, Lorule, is in even worse shape. [[spoiler:In the end, it looks as though Hyrule will be saved at the expense of Lorule, which would make this a subversion... but Link and Zelda then wish on the Triforce for Lorule's Triforce to be restored, saving Lorule, and making this {{Double Subver\|sion}}ted]].
105	* The Twin Worlds of Stark (i.e. our familiar Earth) and the magical Arcadia in ''VideoGame/TheLongestJourney'' have been one and the same twelve thousand years ago, and the biggest danger they face is an uncontrolled collapse back into each other. In this regard, April isn't saving Arcadia only to learn that she also has to save Stark--much rather, she is saving Stark, only to learn that in doing so, she also saves Arcadia.
106	* Similarly, Amy from ''VideoGame/ZanZarahTheHiddenPortal'' saves the world of Zanzarah from the dark forces, but in doing so, also restores magic to her own mundane world, which had lost it long ago.
107	* In ''VideoGame/RakenzarnFrontierStory'', the Realmwalkers take every universe as equally important. And as they play the role of GuardianOfTheMultiverse, it is literally their job to make sure all of them stay safe.[[note]]This doesn't stop the game's creator from blowing up a few for a TakeThat at some franchises, though.[[/note]]
108	* The Shadowbringers expansion has two worlds that must be saved in ''VideoGame/FinalFantasyXIV''. The Source is the game's main world and the First is a parallel world of the Source. In order to prevent an eighth calamity occuring on the Source, the player character is [[spoiler:whisked away to the First to prevent the Flood of Light from destroying that world. Should the First be destroyed, its effects would transfer to the Source since the two worlds are linked. The is made apparent by the Crystal Exarch who comes from a BadFuture where the calamity on the Source happened and plunged the world into chaos and lawlessness.]]
109	* In ''VideoGame/{{Undertale}}'', if the player chooses and persists at the "Genocide" path, as the human cuts through monster after monster, it becomes clear to the survivors over time that they're not going to stop at the monsters' world, but they plan to keep going upon returning to the surface, which only adds to why they're all trying to stop you. [[spoiler:At a certain point in the final minutes of the game, still underground, the fallen child leaves the player's control, has plans that become obvious, and in case you thought different, a short, haunting conversation against says the matter is no longer debatable.]] (In the main version of the story, playing the "Neutral" story or pacifistic, there's a dilemma that emerges -- the monsters of the Underground are trapped there, but the terms of their breaking free means the vengeful king will make war on the human world, and the projected outcome goes, destroy it.)
110	* The plot of ''VisualNovel/YuNo'' eventually comes down to this. [[spoiler:Takuya is whisked to a different dimension, Dela Grante, which is increasingly plagued by earthquakes attributed to an impending apocalypse. Takuya learns from those in the know that 8000 years ago, {{Precursors}} constructed Dela Grante to cycle his dimension in an interdimensional orbit, but a calculation error made the trajectory gradually shift and ultimately hit Earth. A full collision is narrowly avoided, but at the cost of Dela Grante not surviving and its remains crashing into Earth 8000 years earlier.]]
111	* In ''VideoGame/NiNoKuniCrossWorlds'', after progressing far enough into the story, you learn that Levant's corruption is powerful enough that if not put in check it will eventually seep into the Earth as well. Thus by continuing to fight you are saving not only the world of ''Ni no Kuni'', but also the Earth that you came from.
112	[[/folder]]
113
114	[[folder:Web Original]]
115	* The heroes of ''Literature/TheDragonWarsSaga'' must save the magical world they're stuck in to save Earth.
116	* A key trope in the web fiction serial ''Literature/DimensionHeroes'', in which the Dimensional Guardians must find a way to stop two dimensions from colliding with one another.
117	[[/folder]]
118
119	[[folder:Western Animation]]
120	* In ''WesternAnimation/{{Amphibia}}'', this became the goal of the final season. After learning that Andrias [[spoiler:and the Core]] intended to invade ''all'' worlds out there, including Anne's, the heroes were driven to not only stop the invasion of Earth, but to liberate Amphibia.
121	* In ''WesternAnimation/BatmanTheBraveAndTheBold'', when a DepopulationBomb threatens to kill all life on Earth, Batman and Red Hood teleport it to another dimension. It turns out (as in, we find out they already knew) everyone on that Earth were already [[EverythingsDeaderWithZombies zombies,]] so the bomb's explosion was [[NegateYourOwnSacrifice completely harmless]]. Additionally, this episode primarily takes place in an EvilCounterpart world, similar to Earth-3 of the comics. Batman doesn't just want to escape this world, he wants to make it better (since, in this world, TheBadGuyWins is a regular occurrence). He frees the captured heroes, who are now being led by Red Hood, and the villains have been defeated. Batman only leaves when he feels like the native heroes have a good handle on things.
122	* The ''WesternAnimation/CodenameKidsNextDoor'' episode "Operation: P.O.O.L.", where the heroes don't try to just escape the horrible MirrorUniverse. They manage to actually make it better.
123	* In ''WesternAnimation/MegasXLR'', Coop ends up in an alternate reality where he destroyed the Glorft, turned evil, conquered the world, and worse, [[ArsonMurderAndJaywalking lost his gut and became ripped]]. The real Coop decides to take care of his evil self, only to get Megas destroyed. Instead of simply pressing the ResetButton, [[SugarWiki/MomentOfAwesome he steals the alternate Coop's abandoned Megas, leads the Glorft against Evil Coop's forces in a final epic battle, and gets Evil Coop trapped between the universes]]. It's as awesome as it sounds.
124	* One episode of ''WesternAnimation/TheSuperMarioBrosSuperShow'' brings Mario and Luigi back to Brooklyn, but also Bowser and company as well. They have to save Brooklyn and the Mushroom Kingdom from Bowser.
125	* An episode of the ''WesternAnimation/DungeonsAndDragons1983'' cartoon had the kids finally get back to their own world, but Venger followed. When they realize their weapons won't work on Earth, and it's made clear by Venger he'll lay waste to Earth as he did to the Realm, the kids must go back to prevent Venger from following through.
126	* Averting ExpendableAlternateUniverse seems to be the logic WesternAnimation/SamuraiJack lives by in his BadFuture. He repeatedly turns down the chance to return to the past and kill Aku before he could ever take over the world and gives it up to help his new friends. While this may seem LawfulStupid in that he'd negate the BadFuture so he'd never need to save his friends, it may be that he's just too kind to take risks. Thus the best option would be to destroy Aku in the future and then return to the past and destroy him there. Ultimately, [[spoiler:Jack kills Aku in the past, which does indeed erase the future he was sent into--[[BittersweetEnding include Ashi, his lover who he met while he was there]]. Although heartbroken, Jack concludes that [[SetRightWhatOnceWentWrong restoring the Earth]] [[{{Reconstruction}} was worth the cost]]. Jack's allies were implied to have felt the same, as being told of Jack's goal to erase "the future that is Aku" did not keep them from coming to his aid.]]
127	* ''WesternAnimation/TurtlesForever'': The 1986 and 2003 TMNT versions team up to stop 2003 Shredder and save not just their own worlds, but the entire TMNT [[TheMultiverse multiverse]].
128	* ''WesternAnimation/{{WITCH}}''
129	** Downplayed in season 1, because [[DefiedTrope Meridian was isolated from the other worlds by the Veil]] specifically to contain [[BigBad Phobos]]. However, Earth would still be endangered due to portals opening between the two worlds, enabling Phobos's forces to manifest on the heroes' hometown.
130	** The second season ramps up the SlidingScaleOfMuggleInvolvement, leaving the Guardians increasingly playing defense even on their own turf. In part because the Veil is now down, and also because Nerissa's goals include stealing Will's Heart and taking over the whole universe. [[spoiler:Come the finale and the newly empowered villain Cedric outright decides to attack their hometown on Earth, [[ToUnmasqueTheWorld in full view of everyone]].]]
