History Main / MergedReality

* Happens with the ''{{DC}}'', ''{{Wildstorm}}'' and (sorta)''{{Vertigo}}'' universes at the end of ''{{Flashpoint}}''. After the Flash is revealed to have accidentally broken the timeline, leading to events in Flashpoint, Pandora merges the three universes together to fix the problem. (why she can't simply undo the damage and has to merge in the other universes is not explained) This leads directly to the DC reboot and the ''{{New52}}'', with some Wildstorm and Vertigo characters and concepts being added to the DCU.

* A MarvelComics storyline had the FantasticFour aiding their [[HeelFaceTurn enemy-turned-ally]] Amazon Thundra to merge her LadyLand [[AlternateHistory Alternate Future]] of "[[MeaningfulName Femizonia]]" with the [[NoWomansLand misogynistic]] world of Machus to form a composite future of (theoretical) equality between the sexes. The men and women still fight each other constantly with deadly weapons, but Reed Richards just {{Handwave}}s that as the [[ProudWarriorRaceGuy Proud Warrior Race]] version of SlapSlapKiss. Naturally, Thundra finds this world boring and [[AllTheMyriadWays seeks out an analogue of Old Femizonia to settle in]].

* This is what essentially would have happened if Buffy hadn't stopped Glory in ''BuffyTheVampireSlayer''. It would have been only temporary, though.

* ''ParallelTroubleAdventureDual''
* ''{{Yumeria}}''

* Used mildly in the [[http://www.onemanga.com/Tsubasa_Reservoir_Chronicles/69/05/ Shara/Shura]] [[StoryArc arc]] of TsubasaReservoirChronicle. In this case, the main characters don't even realize they are time traveling, but their actions do result in friendlier interactions in the 'original' world. Not that there aren't consequences....

* The DC and Marvel multiverses briefly merge together into the Amagalm universe in ''DC vs Marvel''. Years later they are merged again(but not creating the Amalgam universe) in the {{JLA-Avengers}} crossover.

* Creator/DianaWynneJones's book ''[[{{Chrestomanci}} Witch Week]]'' ends this way, with the merging character explaining to the cast that they will all melt quietly into the people they really are in the other world. (Since they're probably going to be burned as witches otherwise, this sounds quite appealing.)
** It should be noted: 'probably' in context means '[[TheEndOfTheWorldAsWeKnowIt if the world isn't destroyed first]],' which is what will happen if their world [[spoiler: (which was ''not'' supposed to exist)]] isn't merged with the other one.

One possible ending to stories in which the hero or heroes are [[TrappedInAnotherWorld trapped]] in an AlternateUniverse is to somehow force the universes to merge or collapse into one single time-line that exhibits (hopefully the best) features of both. A way to SaveBothWorlds, if you will.

* [[spoiler:Chao Lingshen]] from ''MahouSenseiNegima'' tries to expose the magical population to the {{muggles}}. When confronted and asked why, she claims it's for this trope.
** Fate's ultimate plan [[spoiler:is to move all the inhabitants of Mundus Magicus into a super-powerful LotusEaterMachine / {{Heaven}}.]]

* The ''BackToTheFuture'' movies, the first had this happening on a small scale to the protagonist and his family.
* Subverted in the movie ''{{Idiocracy}}''. The main character, after being a HumanPopsicle for 500 years, wakes up to find the world has taken a drastic turn for the worse intelligence-wise. He proceeds to look for the time machine that must exist by now to tell the world what awaits them if they do not change. [[spoiler:Due to the world being too stupid to have invented it, there is no time machine. He instead chooses to teach the world he's in now to improve.]]
* Caesar is all about this in ''[[PlanetOfTheApes Battle For The Planet Of The Apes]]'', since he knows that his parents came from a world where the world was destroyed in an EarthShatteringKaboom. We never find out if he managed it or not, fans disagree.

* Inverted in TerryGoodkind's ''{{Sword of Truth}}'' series. In the final book, [[spoiler:as a final solution to the gigantic [[TheEmpire evil empire]], full of people who [[strike:refuse to see things his way]] were trying to kill anyone and everyone who doesn't see it their way, protagonist Richard Rahl uses his new-found cosmic powers to create a new, separate world without magic, where he puts all the undesirable people. (Which is pretty much what they wanted all along.) This new world, with no magic and full of evil religious fanatics, is implied to be the origin of our world.]]

* Two different perspectives on this are given in ''ThePendragonAdventure'' series. Each Territory has a Turning Point where it can either fall into chaos or continue on peacefully. Bobby always aims for the second option, trying to win over Saint Dane. However, Saint Dane talks of "The Convergence", saying that he's ''also'' wanting to make Halla (the entirety of the Territories and the universe) a better place - but the chaos has to come before he can achieve his goal.
** At the end of ''The Pilgrims of Rayne'', after losing to Saint Dane on Ibara, Bobby forcefully traps himself and Saint Dane on the island territory in an attempt to make it better. This might also count as a TenMinuteRetirement.

* The twist resolution to [[spoiler:''Dragon's Ring''.]] The protagonist had been openly working to ''destroy'' the world all along, but it turned out that wasn't the only way to [[spoiler:save all the worlds.]]

* Arguably the entire plot for the first season of ''Series/{{Heroes}}'', which deals with one person who can paint the future, several people with premonitions of it, and one person who can actually time travel and change it. By the end of the season, the foreseen impending disaster is actually averted, albeit in a less than ideal way.

* Reversed in the computer game ''TheLongestJourney'': the idea is to ''prevent'' the two worlds from combining, at least under the current uncontrolled conditions.

* A variant of the TimeTravel version is the goal of ''VideoGame/ChronoTrigger'', and the AlternateUniverse version is the goal of its sequel, ''VideoGame/ChronoCross''.
* A rare example that's neither: In ''{{Persona}} 2: Innocent Sin'', [[spoiler:the heroes '''lose''' in the end, resulting in the death of one of their own, and the entire world exploding, with only a city that had earlier separated from it surviving. Philemon, one of the representatives of the PowersThatBe offers them a chance to remake the world, altering it so that it's 'better', and the events of this game would never happen]]. They take it... but as seen in Eternal Punishment, it doesn't entirely work.
* Subverted in ''FinalFantasyV'', where this is exactly what OmnicidalManiac Exdeath wants to happen and the heroes are trying to ''prevent''. As it turns out, the [[MacGuffin power]] he's after was sealed by splitting the world in two hundreds of years ago, and he can only release it from the Dimensional Rift by reuniting the worlds (which entails the destruction of the [[CosmicKeystone Crystals]], so with or without Exdeath actually claiming his prize and wreaking havoc with it, everybody's pretty much screwed).
--> '''Exdeath:''' I will return the world to its original form!
--> '''Bartz:''' To a world of evil!
--> '''Exdeath:''' Are you even listening to me?
* One of the items in the ''{{GURPS}}'' sourcebook ''Magic Items III'' is the Healer of Worlds, a MacGuffin designed specifically for this purpose.
* Something like this is done in the canonical ending in ''ValkyrieProfile''.
* The plot of the ''WhenTheyCry'' series.
* In ''VideoGame/FinalFantasyCrystalChroniclesRingOfFates'', the villains are attempting [[spoiler: to use the power of [[RealityWarper Star Singers]] to create a world in which their [[UltimateEvil god]] has power over the planet. The plan mostly succeeds, however they only have the ability to choose between a vast list of [[AlternateUniverse possible realities]]. In the end the heroes fulfill the trope in full, using their powers to create a truly new reality.]]
* In ''MortalKombatVsDCUniverse'', the BigBad is Dark Kahn, a merged version of Shao Kahn and Darkseid, who starts merging the realities of Mortal Kombat and the DCUniverse, while feeding off the rage of the characters. He's also playing the heroes and villains of each world against each other, which think that the other is an invading army. Eventually, though teamwork, Superman and Raiden manage to defeat Dark Kahn and split him into two. Unfortunately for them, Darkseid and Shao Kahn end up in each other's worlds.

* Lex Luthor tries this in season 1 of [[FanFic/ImAMarvelAndImADC I'm a Marvel... And I'm a DC]]. Not in ''his'' universe, but the ''real'' universe. His goal was to have comics stop progressing when it was just him and Superman, back when times were simpler and they were important.

[[folder: Western Animation]]
* The entire plotine of the ''DannyPhantom'' episode, "The Ultimate Enemy." If you believe that the episode was a time loop, it is a bit subverted that the timeline was fixed ''first'' not by the hero, but by [[TimeMaster Clockwork]] who triggered the good future when he stopped the Nasty Burger explosion that caused the BadFuture in the first place. The rest was obviously Danny making the right decision.

* Subverted like mad with TheDCU character Super***-Prime (he used to be Superboy-Prime until DC lost the rights to the name Superboy, now he's Superman-Prime for no good reason). His motivation is that he wants to bring back his world, the "perfect" world... and he's willing to blow up every ''other'' world in existence to do it. Moreover, he has no problem killing anyone who gets in his way (or anyone who doesn't), because he judges them to be "stupid" versions of people who'd exist on his world. Yes, to some extent, he is [[YouSuck a superpowered avatar of fanboy rage]].

* A rare example that's neither: In ''{{Persona}} 2: Innocent Sin'', the heroes '''lose''' in the end, resulting in the death of one of their own, and the entire world exploding, with only a city that had earlier separated from it surviving.

* The DC and Marvel multiverses briefly merge together into the Amagalm universe in DCvsMarvel. Years later they are merged again(but not creating the Amalgam universe) in the JLA/Avengers crossover.

* Lex Luthor tries this in season 1 of TheRandomverse. Not in ''his'' universe, but the ''real'' universe. His goal was to have comics stop progressing when it was just him and Superman, back when times were simpler and they were important.

* On ''{Sliders}'', the BigBad of the last season is trying do, he experiments by first merging people from different universes together.

* Done absolutely awesomely in OrsonScottCard's ''Pastwatch''. The plot is rather complicated, but suffice it to say it emerges that [[spoiler: our own timeline is the product of interference from ''another'' timeline, in which the Tlaxcalans of Central America conquered Europe and possibly the world. (The author does an excellent job of making it sound plausible). The people of ''that'' timeline viewed the Tlaxcalan invasion as the greatest catastrophe in human history, and so they altered their own timeline, by motivating Christopher Columbus to sail west (with a holographic God). Of course, in the story our own timeline appears to be headed for human extinction, so the characters make their own alteration, preventing both the Central American and European civilisations from wiping each other out. They are apparently more successful than the original alterers.]]

Similarly, stories involving TimeTravel may find their resolutions revolving around changing the past in order to turn the current world into a better one.

Either way, the current world is headed to nothing short of [[TheEndOfTheWorldAsWeKnowIt disaster]], so the only choice is to put it back a different way.

** It's also implied that Fate's ultimate plan [[spoiler:is to move all the inhabitants of Mundus Magicus into his own world.]]
** Confirmed. Except [[spoiler:it's not his world, its a super-powerful LotusEaterMachine / {{Heaven}}.]]
*** Also, the organization that Fate is a part of, Cosmo Entelecheia, is Greek for "To Perfect The World".
* The ultimate goal of Les Soldats in ''{{Noir}}'' is allegedly this. However, they never define what their vision of a better world is, and they appear to not have made any noticeable progress to this ideal world in 1,000 years of work as an AncientConspiracy, so one should take their official long-term goals with a grain of salt.
** And then there's Altena. She rejects the legacy of the Renaissance, Enlightenment, Industrial Revolution, and Sexual Revolution; [[DeliberateValuesDissonance this is good]]. She thinks that the best way to get the rest of the world to appropriate her message is to kill everybody, because people can't sin if they're dead; [[AndThatsTerrible this is not]].
* Light Yagami's abition in ''DeathNote''. And he hopes to be the [[AGodAmI GOD of that new world]] too.

* Caesar is all about this in ''[[PlanetOfTheApes Battle For The Planet Of The Apes]], since he knows that his parents came from a world where the world was destroyed in an EarthShatteringKaboom . We never find out if he managed it or not, fans disagree.

* ''ShinMegamiTenseiNocturne''. The entire point of the game. Any world you want. Problem is... is any of the worlds you can choose truly... better?
