History Main / SaveBothWorlds

* 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 cheap shot at some franchises, though.[[/note]]

Contrast with UpTheRealRabbitHole, 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.

'''T'Pol''': Good. Then you've already come to the conclusion that, without humanity, there's no one to combat these [[AbusivePrecursors Sphere-Builders]]. Their [[WorldOfChaos Expanse]] will continue to grow, encompassing one system after another, including Vulcan. Your world is no longer the only one in jeopardy.

* In ''WesternAnimation/BarbieAndTheSecretDoor'', the heroines must save the magic of all realms of Zinnia.

* 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/AdamWarlock 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.

** 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.

%% * Franchise/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.

* An episode of the ''WesternAnimation/DungeonsAndDragons'' 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.

* ''FanFic/TheCaptainOfTheVirtualConsole'' has this as its plot. Gancena must save the video game worlds and her own.

%%* The ''Literature/ApprenticeAdept'' series; Stile is a native of science-based Photon, but is brought to magical Phaze as part of a GambitRoulette to correct an imbalance that would destroy both worlds.

* ''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 cataclism happening either in the 21st or 31st century, but both of them had something in common: he himself would die as Time Fire. His plan in sending the Timerangers to the past was to ensure that the cataclism 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]].

%%* 'Manga/DragonDrive' - A video game leads to a virtual world that acts as a stepping stone to an alternate world. With Dragons.
* 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.

* ''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.

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. If the more mystical of the worlds is based in a computer realm, expect [[EverythingIsOnline a deadly effect on your hometown hospitals and roads]].

%%* 'DragonDrive' - A video game leads to a virtual world that acts as a stepping stone to an alternate world. With Dragons.

* Franchise/PrettyCure has this in every series.

* In Franchise/WonderWoman storyline "Judgment in Infinity", a group of heroines come together to save five parallel Earths from the [[EldritchAbomination Adjudicator]].

* 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 as it becomes clear why the human child is wanted dead -- 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.)

* In the fourth ''Animation/PleasantGoatAndBigBigWolf'' film, ''Mission Incredible: Adventures on the Dragon's Trail'', the goats learn that dragons are responsible for [[PaintingTheFrostTheWindows 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.

* 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.]]
* 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.

* An episode of the ''WesternAnimation/DungeonsAndDragons'' cartoon had the kids finally get back to their own world, but Venger followed.

** ''Anime/DigimonFrontier'' flirted with the idea an attack on the real world in the penultimate episode's cliffhanger, but the BigBad never actually made it there.

* ''Anime/SonicX'': Towards the end of the second series, 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.]]

* ''VideoGame/SonicTheHedgehog'' has this happen twice. Once in ''Sonic Rush'' Blaze is trapped on Sonic's world with the Sol Emeralds. If the Sol Emeralds aren't returned, both worlds will be destroyed. Again in ''Sonic Rush Adventure'', except [[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.]]
