All the Myriad Ways

""Ours is the only reality of consequence.""

- Teal'c, Stargate SG-1, immediately after killing his own Alternate Universe counterpart.

Anything can happen in an Alternate Universe, since it isn't our world. People could be talking lizards over there, or maybe their Abe Lincoln was never assassinated, or maybe they can all fly. But if heroes from our world visit the Alternate Universe, they won't care what happens there. Typically, neither do the audience.

Suppose Bob from Earth-2 dies. Our heroes still have Bob from Earth-1, the Bob they know and (mostly) love, so what's the loss? Earth-2 Bob was a stranger to them. As long as Earth-1 Bob escapes back through the portal alive, nobody will shed a tear. You'd think Bob would be unnerved by seeing himself murdered, but Earth-2 Bob was just as much of a stranger to him as to the rest of the dimension-jumpers. (Merely the fact that our world is "Earth-1" tells you how little respect there is for the alternates.)

This goes further than individual death. Absolutely anything horrible can happen in an Alternate Universe -- Zombie Apocalypse, life-threatening plague -- and our Earth will still be safe, if we can close the portal. Many heroes will not leave the Planetville of the week until its problems are solved, but for the Alternate Universe, all they care about is getting out alive.

The reason for this is that an Alternate Universe often feels like a cheap copy of our own. It's just an extra us, so its people aren't unique characters. Under the Second Law of Metafictional Thermodynamics, that makes it expendable. It is extremely rare for so much as a single refugee to escape a doomed Alternate Universe, because that refugee will ruin Cast Speciation for the Earth-1 version unless the refugee will become a Suspiciously Similar Substitute. In universe, this is often simply pragmatism from the characters: Works that feature alternate universes heavily often use the "infinite variations" model of the multiverse. The leads simply can't afford to worry about saving every single possible universe.

Things are even worse if there's only one world, but Time Travel can change it back and forth. People in the future can die a hundred times each, but since the Time Travel will bring them back, who cares?

A related issue is that too many alternates can cheapen established stories. If the heroes have saved Earth from the Planet Looters, the Zombie Apocalypse, The Virus, the Nietzsche Wannabe and the Circus of Fear, that's impressive. If there's an Alternate Universe for each one of those villains winning, it means our heroes aren't impressive -- they lost as often as they won, and we're from the universe where they just happened to win five times in a row. This gets even more Egregious when there are infinite alternate universes; for every event in "our" universe, there are infinite others in which it didn't happen...

On the other hand, "You can have an infinity of apples but still not a single orange", as a scientist explained this theory: So it's still perfectly possible that the heroes win everywhere, or at least more often than they lose.

This callousness doesn't apply to worlds that are less obviously mirrors of our own. Wonderland, Narnia, and dimensions with only nonhuman life are all technically alternate universes, but they're so different that losing them actually hurts.

This trope is named after a short story by Larry Niven that is essentially a Lampshade Hanging on the trope.

Compare For Want of a Nail, which is the Time Travel equivalent.

Anime and Manga

 * Either averted or played straight (depending on how you look at it) in the anime/manga series Bokurano.
 * Noein plays with this. All the Dragon Knights believe that universes outside their own are somehow virtual and unreal, Haruka is arguing with them all the way, and Karasu is the only one who's convinced/realizes that the "virtual universe" thingie connected to a real universe rather than creating an artificial existence. In the end, it's up to Tobi to drop the anvil - that peoples' existences are confirmed by interactions and specifically bonds, not by observing a collapsing waveform.
 * So basically he's saying octopi, planet earth and the universe don't exist?
 * No, they exist because they have been observed and acknowledged. The series runs on the principle of Schrodinger's Cat (the theory not the trope).
 * Super Robot Wars The Original Generations had an inversion and subversion to this. In it, a group of heroes fleeing their own universe after a coup against the corrupt Federation fails, and they try to rebuild their powerbase in our universe. They get several things right, but are surprised when several major things that happened to our universe just didn't happen in theirs. The subversion lies in their belief of recruiting the heroes of OUR universe to help them at any cost, and the main characters treat them as important as any other person.
 * However it's hard to say if this really counts, because aside from one main female characters' alternate counterpart who is so radically different they don't even know it's her until the end of the game, the rest of the alternate universe characters are all people that don't exist in the main universe, or at least have never appeared in story there. It's hard for the main characters to write Axel off as "oh it's just an alternate Axel Almer" when they don't know of any other Axel Almer.
 * The anime Parallel Trouble Adventure Dual, which features two parallel universes, take this to the ultimate extreme by having the characters seemingly view themselves as more important than everybody in both worlds. At the end of the series.
 * In Haruhi Suzumiya (Disappearance) Kyon had to destroy the Alternate Universe that, to recreate his own Universe.
 * In Dragonball Z, Cell comes from a timeline different than that of Trunks or the regular timeline. While the regular timeline and the one Trunks is from are eventually saved, no one seems to ever care about this third timeline and after awhile it's simply forgotten.
 * Somewhat justified. The implication of Cell arriving in the main timeline is that people on Earth in that timeline are already dead (because Cell killed them before traveling) or alive and well (because the Androids were killed by Trunks, forcing Cell to kill him and came back in time to find them instead).
 * It's also worth noting that all the Z Fighters are dead in that "forgotten" timeline as Cell killed the Trunks from it. So it is justified as the main protagonists of the story (with maybe the exception of Bulma and side characters like Chi-chi) are gone.
 * The central conflict in Higurashi no Naku Koro ni Rei is about this. At first, is willing to do ANYTHING to get back to her 'own' universe without even contemplating the morality of it, up to and including . Then as she relaxes a little bit and lets herself become a part of the universe she contemplates the good parts of it and why it could be wrong to regard her original universe as a universe A and the one she's currently inhabiting as a universe B. In a Bittersweet Ending typical of the series, she ends up committing an unspeakable sin to get back home anyway, only after acknowledging the meaning of it enough to be truly scarred by it. Sure, another characters tells her 'it was all a dream,' but it was rather probably an attempt at comforting through deceit.
 * Asura Cryin spends a good deal of time getting us acquainted with the main universe of the show, though it's hinted early on there's another one. When several characters from the main universe (which is actually World-2) are killed off, the show changes gears and goes to World-1. While Tomoharu knows he doesn't belong here, an effort is being made to Save Both Worlds; they're both considered equally real, though there's still only one Tomoharu between them.
 * Inverted in 11eyes. 3 characters  get brutally murdered.  {{spoiler|In the end, not only does the person who did it get off clean because she was {technically) the good guy, but everything ends all and well, because in the world where they end up in, has all three of them alive and well, even though they are not the same characters we have come to know and love}}.
 * The Code Geass manga Nightmare of Nunnally has the heroine use her Geass power to see an alternate universe - namely, the "mainline" universe of the Code Geass anime. No interference here, though Nunnally says she's happier with the manga reality, mainly since.
 * The Code Geass manga Nightmare of Nunnally has the heroine use her Geass power to see an alternate universe - namely, the "mainline" universe of the Code Geass anime. No interference here, though Nunnally says she's happier with the manga reality, mainly since.

Comic Books

 * Comic books have lots of alternate universes, from the DC comics Elseworlds and "imaginary stories" to Marvel creations like "What if?" and Marvel Zombies. Almost every one of these ends with a bucketload of corpses, or maybe the entire universe getting destroyed. It's not our Wolverine, we don't care if this one dies.
 * This is even more blatant in Set Right What Once Went Wrong stories. The cover of Days of Future Past boasted "In This Issue: Everybody Dies!". It was true: Everybody did die, but in the dark future that wouldn't come to pass if our heroes in the present succeeded.
 * Except it was revealed that time travel in the MU just splits off alternate histories, so the original Crapsack World timeline still happened, just not in the mainstream books; the attempt didn't save the DOFP X-Men.
 * Heavily subverted in Paradise X, in which a number of heroes go to immense lengths to save alternate universes (though some prove unsalvageable). The only thing they won't do is travel into the past to reset a universe, since this will just create another alternate (stranding the people they were trying to save). It pays off--even archvillain Annihilus from the Negative Zone is willing to help out, out of gratitude for the assistance.
 * Marvel at least makes a small concession to this trope, in that the 'main' universe is Earth-616, implying that it is just another one among many. DC, on the other hand, traditionally had its main reality as Earth-1, implying it to be the real world that all the others are merely copies of. Since their latest multiverse shakeup, however, the main world is now New Earth, with 52 numbered alternates in existence.
 * Several series of Marvel's Exiles title deal with characters in some way exiled from their various realities, usually previously unseen, working to steer the course of events of other realities. A 2009 series seemed to this reader to be running on the principle that if a reality stopped being interesting to read then it'd cease to exist, or is that too literal? (The series itself ended at issue six.)
 * Settings, alternate or not, that may not be attracting enough audience to continue publication, often have an apocalypse to stimulate attention, and may then be cut off anyway. Marvel's "2099", "Heroes Reborn", Batman's "No Man's Land", and Wildstorm's "World's End" are examples of apocalypses where the other factors may apply.
 * Crisis on Infinite Earths was a series specifically designed to destroy Alternate Universes in The DCU. There were so many around that the Powers That Be felt they cheapened the "real" universe, so their death was mandated. As usual, the ending is considered happy even though several universes just got wiped out, along with all 6 billion-plus people (and trillion-plus aliens) in each one.
 * The Multiverse was such a constant until Crisis that people did, in fact, care about the people in most of the more prominent universes. In Crisis itself, the death of the original Crime Syndicate is just heartbreaking; they're supervillains, but they're still part of the world, and they fight more bravely for it than just about anybody else does for theirs. A few of them run headlong into a wave of antimatter by the end...sorry, I'm getting a bit choked up here...
 * This is rather subverted in Infinite Crisis, as those who saved the single remaining universe decide that they saved the wrong Earth. Infinite Crisis is all about trying to stop these former heroes from re-writing the world in their mold. They nearly succeed.
 * The Multiverse was brought back at the end of Infinite Crisis, because of the temporary return of the Infinite Earths caused there to be too much aspects to return which made it impossible for New Earth to return to its original Post-Crisis state. Because of the events of 52, Infinite Crisis' immediate sequel, fifty one of the fifty-two were now radically different from each other. People were happy about this... until Countdown to Final Crisis came along and destroyed one earth (but not its universe), and destroyed an entire universe so utterly that it had to be rebuilt from scratch. Then a deadly mutative virus permanently altered all life in that same rebuilt universe. Grant Morrison has officially stated that Countdown never happened (minus Earth 51 being destroyed which is what caused Final Crisis).
 * In the comic version of Wanted the Villain Protagonists jumped to other dimensions with the specific purpose of stealing things (such as an irradiated condom) and killing superheroes. While they were there they felt perfectly free to trash other realities to make their own go the way they wanted.
 * Well, to be fair, they were explicitly villains. It's not as though their moral behavior in their own home dimension was any better.
 * Usually subverted in The Authority comics in that the title group (who have a Cool Ship capable of traveling between realities) are more than willing to move into other realities and tell the locals how things should be done - Or Else!
 * They do show respect for other realities at times, usually as long as they're run right - or if the Authority wants their help. In one instance they had to temporarily evacuate the world's entire population to other realities, and are seen negotiating with The Meritocracy, their gender-flipped counterparts in a gender-flipped reality. (They in turn put the decision to a worldwide vote rather than decide for themselves, resulting with a majority agreement from that world's people.)
 * On the other hand, in one arc they destroy an alternate Italy and in another they cause the death of everyone on an alternate earth trying to power their ship.
 * Age of Apocalypse killed off almost the entire alternate cast, with only a handful escaping back to 616, but the series still had a cult following and Marvel eventually acceded to demands that Blink be brought back, meaning that someone must have cared.
 * On a Post-Zero Hour encounter between every possible version of the Legion of Super-Heroes and the Time Trapper, the heroes criticize the trapper for toying with their histories, claiming they're not variants but people.
 * Subverted in the first issue of Planetary. Doc Savage Expy Doc Brass and his Super Team created a machine that uses a short-lived pocket multiverse as a supercomputer. Unfortunately for them, the pocket universes experience billions of years in the real-world seconds before they're destroyed, and a familiar-looking super team from one of the universes figures out what was going to happen to them -- and how to get to the universe where Doc Brass and friends were.
 * In Sonic the Hedgehog Archie comics, the second Robotnik came from a universe where he had already killed all the main characters. This second timeline is simply forgotten.

Fan Fiction

 * Chrono Trigger: Crimson Echoes had three timelines, the one that was created after the Big Bad from the original game died, one where the myths of a certain legendary sword never existed, and one that was mentioned in the official sequel Chrono Cross, where the aforementioned Big Bad was not around to influence evolution and a long-dead race was revived to wage war on the now-ordinary humans. This fan-game's Watcher kinda doesn't like that these alternate timelines exist, as his workers, if you did something to muck up the timeline to make it different from normal, will not allow you to return to base until you make the necessary changes that keep history on track.
 * The Ranma ½ fanfic The Converging Series (sequel to Descents and Inversions): the non-canon main characters are accidental time travellers from different alternate futures who are descended from various pairings of the canon characters. While the Only Sane Man recognizes the existence of coexisting alternate realities (having had to deal with his reality-hopping amazon "half-sister" in the prequel), all the others decide to force the current reality into their own, to ensure their own continuous existence.
 * In Applejack's reharmonizing chapter in the Pony POV Series has her seeing a large number of these staring into the Truth, a pool that shows the viewer all kinds of uncomfortable truths. She sees the Bad Future presented in "Epilogue" along with others. The most heartbreaking is the "Orangejack" timeline, where she discovers that she could've lived perfectly happily without returning home and met the love of her life, even having children. She's heartbroken at the realization her children won't exist because of her choice, until Celestia reveals that universe still exists and they'll live on in that path.

Film

 * The 2001 film The One is about an interdimensional criminal who's been going through every universe and killing his counterparts to steal their lifeforce, and is down to the last one (ours). Grave consequences are implied if there's only one of one person in the multiverse. Strangely enough, despite the multiverse consisting of an infinite number of universes, only 124 or so contain doppelgangers of the killer.
 * Actually, in the movie it is explained that every time a sun turns into a black hole (or something like that) a new universe is created and so far this has happened 125 times.
 * The third Men in Black movie has Griffin, an alien capable of seeing all timelines at once though he's not certain which one he's in. This means that he's often fretting whether or not this is the timeline that something disastrous happens based on minor actions that seem insignificant to others.

Literature
"And I wonder: in how many infinite sets of worlds will I take one more step? And how many countless versions of me will turn around instead, and walk out of this room? Who exactly am I saving from shame, when I'll live and die in every possible way?"
 * The Trope Namer, Larry Niven's All the Myriad Ways, actually deals with an inversion - because new alternate worlds are literally created every second, people no longer value their own lives, because they know alternate versions of themselves will do better if they die -- and why not commit murder, rape, robbery, or suicide, if you were always destined to do so in at least one timeline? The story ends by showing nine very different outcomes to the same story with only the last line changed on a whim of the protagonist.
 * In the story collection of the same name, this is followed by an essay where Niven explains his dislike for the concept of "infinite divergent worlds", reasoning that it essentially nullifies free will, as no one can really choose any action if, in the bigger picture, they choose every action.
 * L. Neil Smith has named this "Niven's Fallacy"; Your perspective is of a single existence at a time, and your actions shape that existence from your perspective. You are you, your double is someone else.
 * Avoided in Diana Wynne Jones's Chrestomanci sequence, where events in alternate Earths do affect events in the main character's world (which isn't ours, and isn't World One, either. Nor is our Earth - we're World 12B.) However, saving a life from another world can throw the whole system into disarray if you're not careful... so any traffic between the worlds has to be carefully regulated.
 * While several of Philip K. Dick's novels and stories happen in alternate or subjective realities, the best is arguably The Man in the High Castle, where a native of a universe where the Axis won WWII discovers an alternate USA (and also reads of a third) where they did not. None of these is our universe. Another is Eye In The Sky, where a group of people each gain control of reality as they individually wake from a coma. Reality in this case is according to prejudice and their wishes, rather than an alternate, but the idea of decisions causing the change holds true.
 * In the Sterkarm novels by Susan Price, amoral tycoons are quite happy to strip-mine the past for natural resources via time-travel. They don't care that by so doing they'll screw up the future, because it's only possible to get to the past of an alternate "dimension", and therefore it's not their future.
 * Played with in the Discworld novel Night Watch, in which Lu Tze tells Sam Vimes that despite there being multiple alternate timelines, and a theory that states everything which could physically happen must happen in one of them, there are nevertheless events which haven't, such as Sam killing his wife, showing that individual choices do matter.
 * Note that this was "Sam Vimes as he is now", implying that in an alternate universe where Sam Vimes grew into a completely different person, he could have done such thing, but that would not be the Sam Vimes who can be recognised as the person he is.
 * Another notable Discworld example is from Jingo, where Sam's PDA somehow gets switched with one from a different timeline. He's horrified as he realizes that, if he had made the wrong choice at the wrong time, a lot more people would have died. Including Vimes himself: "Things to do today... Die..."
 * And then there was Men At Arms, where Pratchett all but says at the start that there were a lot of coincidences and lucky breaks that made the novel's happy ending possible--and then notes that in most universes, it didn't happen that way. "In a million universes, this was a very short book."
 * And Carrot dies
 * It's a plot point in Lords and Ladies, where the weakening boundaries between the Discworld and Fairyland are also causing the boundaries between alternate realities to weaken, enough for the protagonist Granny Weatherwax to remember the lives of her alternate selves. Realizing it helps her.
 * Just to explain how badass Granny is:.
 * She also.
 * In H. Beam Piper's Paratime stories, the home timeline carefully guards the secret of inter-timeline travel and takes advantage of resources from less developed (or completely uninhabited) timelines. The Paratime Police suppress gross exploitation such as inter-timeline slave-trading, but the bottom line is that Homeline's interests come first.
 * After Piper and before Turtledove, there's Keith Laumer's Imperium stories, where the "Maxoni-Cocini drive" allows access to parallel timelines - but at the risk of destroying one's home time-line in an unspecified chrono-nuclear disaster. In fact, our Earth is in the middle of a Blight made up of timelines where the M-C drive went horribly wrong.
 * Laumer's Dinosaur Beach explores parallel time and the Timesweepers who have to clean up the messes left by previous time-travelers while fighting off others who don't want the extant lines cleaned up.
 * And let us not forget Harry Turtledove, who has made a living off of this trope. All of his books, aside from fantasy novels, deal with this trope in some way (and most of them are pretty good) but the most blatant is the recent Crosstime Traffic series, in which eponymous company has solved our earth's Malthusian troubles by developing "Chronophysics" and the technology to go to parallel worlds. Although this mostly gives him license to drop modern teenagers into period pieces, as the books are obviously written for teenagers, and they are pared down from his normal book length, forcing him to sacrifice the plot and world development which is omnipresent in his best works.
 * By the way, the Crosstime Traffic series is a Shout-Out to Piper, as the names of the people who developed the technique in Turtledove's stories are clearly based on those who developed the Paratime technique.
 * Played with in The Talisman, by Stephen King and Peter Straub. When flipping between Alternate Universes of our Earth and The Territories, someone will switch minds with and take over the body of their double from that universe. ...unless they don't have one (as is the case with Jack, the protagonist), where they disappear from their home world and appear in the other.
 * Comes up in the World Gates trilogy by Holly Lisle, especially when one character talks to the fellow that was her husband, only he's a still-alive version in another universe.
 * Roger Zelazny's Book of Amber series also has the Amberites treat the "shadows" as less valuable than the "real" world containing Amber.
 * How much less valuable? Caine murdered one of his alternate selves and dumped the corpse in Amber as part of faking his own death. He was one of the "good" guys.
 * To be fair, the "nothing but us is real" mentality starts to unravel a bit once the main characters figure out that they're not entirely real either - and attitudes towards Shadow-dwellers seem to be at their most sociopathic early in the series, with most of the major characters softening a bit as time goes on.
 * Used in the Roger Zelazny novel A Dark Travelling. In the book, alternate worlds are referred to as "bands", and three of them have become dystopian "Darkbands". The protagonists find themselves caught up in an attempt to liberate a Darkband, with the end result being
 * This is the premise of the Star Trek: Myriad Universes series of novels from Pocket Books, exploring various "what-if" scenarios in the Star Trek universe. This is also the premise of the first novel in the Crucible trilogy, Provenance Of Shadows, which explores both the aftermath of "City on the Edge of Forever" and an alternate universe where McCoy did save Edith Keeler and Spock and Kirk never came back for him, leaving him stuck in the alternate past forever.
 * The Myriad Universe novella A Gutted World is a good example of the Kill'Em All attutide to alternate universes. By the end of the story, the entire main casts of Star Trek the Next Generation, Star Trek Deep Space Nine and Star Trek Voyager are dead. So is the entire Klingon homeworld.
 * In another Star Trek novel, Q Squared, the crew becomes concerned that exposure to alternate universes will cause people to become sociopathic, referring to the phenomenon as "Niven syndrome." This ends up inverted: the only character we see going Ax Crazy does so from the revelation that he only exists in one possible universe, having been killed off in every other one to allow his wife and best friend to get together.
 * Greg Egan plays with this a few times.
 * His short story "The Infinite Assassin" deals with this from the inside: the protagonist is remarkably uniform between worlds, so he can leave one world, complete his cross-universe mission, and return to a completely different set of bosses who'll nevertheless recognize him. His sense of identity is correspondingly diffuse: "I am the ones who succeed."


 * If that's not mind-bonggling enough, check this out: involves being blasted into "Cantor Dust". If your victory condition has been mathematically restricted to a countable (aleph-zero) subset of the uncountably infinite (aleph-one) universes, then you can win in one, you can win in many, you can even win in an "infinite" number of universes. But that's still an infinitesimal subset, meaning you've been defeated in "100% of all universes".
 * "Singleton" is about an AI who's specifically designed not to have alternate versions of herself.
 * Neal Stephenson's Anathem mixes this in, at the end.
 * Robert Reed likes this trope. In a more straight example in his novel, Down The Bright Way, there are thousands of alternate Earths, each of which started diverging around the time apes started becoming more intelligent. In Mere, a race of aliens has quantum sized structures in their brains that cause them to see a faint "aura" around some objects, which they interpret as being glimpses into alternate universes. Hyperfiber in his Great Ship universe is an extremely durable material that gains its strengths from spreading any damage and energy over hundreds of alternate dimensions, making it nearly impossible to destroy.

Live Action TV

 * Played reasonably straight in the Buffy the Vampire Slayer episode "The Wish". By the end of the episode, Giles and Oz are the only main characters left alive; then Giles manages to hit the Reset Button and restore the original universe.
 * "The Wish" is downright gleeful in its desire to have the main characters kill each other: besides vamp!Willow and vamp!Xander killing Cordelia mid-episode, the climax has Oz kill vamp!Willow, vamp!Xander kill Angel, Buffy kill vamp!Xander, and the Master kill Buffy.
 * "The Wish" is an unusual example of this trope in that some characters come to realize that they're living in an alternate reality. Cordelia was brought into that world from the main reality, and Giles and the "white hats" investigated her story. In the end Giles works out how to fix things. When asked why he's sure he even should - why he thinks the original universe would be better than the one he lives in - he answers simply "Because it has to be."
 * In the follow-up episode "Doppelgangland", the heroes have no problem with returning Vampire Willow to her own universe rather than staking her, even though she's killed people there in the past and fully intends to continue killing people once she gets back, apparently it's okay because she's not hurting anyone from our Buffyverse and Willow thinks she's kind of cool. She ended up being staked by Wishverse Oz almost immediately after returning to her universe, but the heroes had no way of knowing that would happen.
 * Star Trek is guilty as hell of this. In the various Mirror Universe episodes (starting with the original-series "Mirror, Mirror"), the heroes from our world either only care about getting home, or throw the Prime Directive out the window. Almost every Star Trek series had at least one episode where a Negative Space Wedgie produces a horror world, and everybody dies fixing the problem, but then our world Snaps Back, so all is well. (For instance, the Star Trek the Next Generation episode "Yesterday's Enterprise," or the Star Trek Voyager episode "Year of Hell".)
 * One of their better half-aversions, where the death of an alternate is treated as acceptable but still tragic, is the Star Trek the Next Generation episode "Parallels." A Negative Space Wedgie rips a hole in time, and five billion plus Starships Enterprise need to get back to their home dimensions. This takes place in a second (for lack of a better term) universe where Riker is captain, and he leads the effort to fix the hole. Then a third Riker tries to stop him -- the third Riker is crazed, from a horrible universe where the Borg have conquered the galaxy, and doesn't want to go back. The second Riker has his Enterprise fire on the third, intending to dissuade it, but the travails of the third ship had already done such a number that even a light shot blew it apart. Riker wasn't happy. The Techno Babble that ended the episode was effectively a Reset Button, and while Worf retained his memory of it, it effectively didn't happen.
 * As a more straight example of the trope, the same episode has the second universe's Geordi dying -- and nobody in his own universe cares, as if they knew their Geordi wasn't "real."
 * On the other hand, that episode also featured some emotion regarding the fate of a parallel character when Troi informs Worf (who'd been bouncing around between realities) that in that particular universe they are married and have children - and when Worf returns to his original universe it's implied that the Worf of that universe won't come back to replace him.
 * Seen in Star Trek Voyager. A time-space hiccup causes there to be two Voyagers in the same place at the same time drawing off the same power source. One of the Harry Kims is killed (and one of the Naomi Wildmans dies not long after being born), so the other Voyager sends their Kim to the functioning ship before self-destructing to take out an invading alien force. Naomi and Harry's status as alternates is never mentioned again. This is somewhat an inversion of the trope, since it is implied that the destroyed Voyager is the "real" Voyager of the series! (though this, too, is never again mentioned)
 * Speaking of Voyager, the episode ?Course: Oblivion? may have averted this, because the death of the other crew is portrayed as a true and tragic loss.
 * Except that that episode is not a alternate reality. The destroyed Voyager crew are real creatures from our Voyager's universe, they just had come to think they were the real Voyager crew when they were in fact liquidy creature things.
 * In Star Trek Deep Space Nine, there is an episode where Time Travel Disease keeps sending O'Brien forward in time to see himself die. (See: O'Brien Must Suffer). He goes to great lengths to save himself each time until the disease kills him, at which point Alternate Timeline O'Brien goes back in his place to save the station. In a subversion of the main trope, Alternate O'Brien feels very bad about Regular O'Brien's death
 * Similarly, the Heroes episode "Five Years Gone" is set in a dark future with a high body count, none of which will matter if our heroes prevent the dark future from happening. And in season two, Peter visits a future where ninety-three percent of the population is dead. That is, the entire human population. Of Earth. The planet.
 * The season two example is made worse by the fact that Peter's girlfriend is abandoned there when his powers deposit him back in the 'present'. So he attempts to save her by stopping that future happening... but doesn't that mean that it would be impossible to rescue her?
 * It's just as likely she'd reappear at the proper time in this timeline. It could be like throwing a dart at a dartboard only to have someone move the board before the dart hits; the dart wouldn't cease to exist, it would just hit the bare spot on the wall where the board used to be.
 * Yes, but... if you throw the dart and someone takes away the board after it hits, the dart will go away with it. So...
 * One of two things can happen: Either he changes the future, and past him now teleports to the new future and leaves her there, or past him still teleports to the Bad Future, in which case he could still save her by traveling back to his past self and coming to that future with him, or just keeping his past self from taking his girlfriend. Either way he'll have to do some time traveling if he plans on bringing her back to the present.
 * It's also interesting to note that in Season 3
 * Season 3 also introduced yet another possible ugly future which contains, among other things, But none of it has happened yet.
 * Neither will it happen, since that future is deaded as well.
 * Oh, Stargate SG-1...
 * In the alternate universe seen in "There But For the Grace of God", the Goa'uld actually succeed in conquering Earth and killing the counterparts of SG-1 (except for Teal'c, who never defected from Apophis in this universe). (Teal'c got to die offscreen when the base was programmed to self destruct.)
 * As an exception, "Point of View" had "our" team travel to an Alternate Universe to help stop the Goa'uld invasion of Earth (although they still did it only after they found out that the alternate Samantha Carter couldn't stay in their universe).
 * Although, oddly, this episode, while not following the trope, does explicitly state it. Teal'c (rather nonchalantly) kills his alternate, and when he's questioned about it by his (incredibly freaked out) team-mates, he doesn't hesitate to matter-of-factly state "ours is the only reality of consequence". While this seems unusually callous of Teal'c, Fridge Brilliance may be relevant: he's The Atoner, so he would be particularly willing to kill a version of himself who was still guilty of what the "real" Teal'c was trying to atone for.
 * In the episode Ripple Effect, Alternate Dr. Fraiser (who somehow only popped up in one of the 20+ SG-1 teams along with Carter's snake-brained love-interest Martouf; both are dead in this world) comes from a version of Earth where the Ori plague was still ravaging the world and a cure was still unfeasible. Alternate Fraiser outright demands that her reality be taken seriously by Stargate Command, and she receives help (their cure) from them.
 * Yes, she receives the cure, but only after being told multiple times by General Landry that he can't place her universe's needs above his own. For a while, it seems like this trope will be played straight and it is only because SG-1 manages to save the day AND figure out a way to get the alternates back home that Alternate Fraiser's Earth is saved.
 * The incident with Dr. Frasier's still-alive version turning up also nicely averts the 'Bob-2 doesn't matter' segment of this trope, in that everyone who had gone through her death was treating meeting this version as a rather special and warm opportunity.
 * The episode does also follow...or perhaps invert the trope: one of the other SG1 teams is planning to sacrifice "Earth-1" to save their own Earth.
 * That episode was a pretty thorough exploration of this trope, as IIRC, there was quite a Not So Different vibe going on with our SG-1 and the treacherous SG-1.
 * Recently subverted in the audiobook "Gift of the Gods", which revealed that Daniel Jackson from "our" universe was Killed Off for Real before the episode "Fair Game" and replaced by an alternate universe counterpart.
 * The main role of O'Neil's friend Major Kowalski is to die in every single timeline, whether they find it or create it with time travel.
 * In the season 10 episode "The Road Not Taken", Carter and her counterpart in another universe are experimenting with an ancient device simultaneously. Something goes wrong (of course) and our Sam is transported to the other side. The other Sam wasn't so lucky. No one from the other side seems too upset about this, whereas our SG-1 is extremely worried for the duration of our Sam's absence.
 * Played with in the movie Stargate: Continuum. The team gets sent to an alternate timeline where the stargate was lost at sea and the SGC was never founded. When they suggest that they use the stargate to travel back in time and set things back the way they were, the alternate universe Landry chews them out for thinking they had the right to alter the lives of every human on the planet.
 * Stargate Atlantis subverts this in "McKay and Mrs Miller"; the techies have no qualms doing great damage to an alternate reality until they find out that life also exists in it (a chance that was considered astronomically small).
 * Another Atlantis example is the penultimate episode:
 * Sliders both avoids and endorses this trope through its first two seasons. Despite an agreement not to interfere with the worlds they arrive in, the Sliders tend to get involved in local politics and generally try to make things better. Unless they are on any kind of doomed world, in which case they typically just try to survive until the jump, unless the total apocalypse will come before the wormhole, in which case they're destined to stop it.
 * They also show a great deal more concern when one of their doubles dies, and have at several points considered staying behind to "fill the gap", before being talked out of it by the others (usually Arturo).
 * As the series went along, things became more polarized overall on this subject. The fourth season has Quinn refer to his home Earth (the one the show started at, ) as 'Earth Prime' constantly, and many episodes focus on how 'wrong' a world is when X happened instead of Y (one ene suchcomes to mind - episode 2 of that season, where they encounter a world focused on religion instead of technology. Because all of the science didn't somehow predate their modern technology, it was somehow backwards... all somehow gathered from a glance at a newspaper). This is the same season that introduced a massive cross-reality war between mankind and their Cro-Magnon ancestors.
 * Similarly, in Doctor Who, Mickey decides to stay in the parallel universe, replacing his counterpart Ricky, instead of going home, because he feels he can help make this world better. (And because his alt!grandmother is still alive.)
 * And Rose is considered to have as much of a "happy ending" as she can without the Doctor -- her mother and father are reunited. Only it's the parallel counterpart of her Dad -- the home version is still dead, and the local version of her mother is not around for various reasons. (This incidentally avoids confusion and expensive CGI, since no main characters now have living alternates.)
 * The season 4 finale confuses things once more by having make a herculean effort to contact the Doctor to warn him of a crisis that threatens every universe. The Doctor's world isn't so far into crisis as the alternate one, where "the stars are going out". By the end, a reshuffle has taken place:   Meaning that there's a character in the alternate universe who is - sort of - the counterpart of a character in the Doctor's universe, even though he originates from the Doctor's universe himself. Confused?
 * The original series also subverts this by having the Doctor traumatized by seeing an alternate Earth being destroyed in the story "Inferno".
 * Painfully deconstructed in Farscape's final season episode "Prayer". Long story short, John needs some information, and to get it  an alternate universe where everyone on Moya was combined for some reason. And   Of course, he also had reason to believe that they were all going to die within the arn if he hadn't become involved.
 * Hercules: The Legendary Journeys subverted this trope: Early in the show's run, one episode featured in a throwaway Mirror Universe where everyone's personalities were swapped: Herc was an evil despot, his Sidekick Iolaus was a cowardly jester, Ares was the God of Love, etc. Many seasons later, after Iolaus had been killed off, Herc wound up with mirror-Iolaus, who was developed into an actual character.
 * In Lexx, they simply abandon their own universe and jump to another after dooming the first one to get consumed by an armed menace...
 * OUCH, that hurt!
 * You win some, you lose some.
 * In Seven Days, it is not unusual for most of the main cast to have killed each other before a Backstep.
 * In Kamen Rider Decade, something is causing alternate realities to meld together, so the Kamen Riders entrust Decade with the task of destroying dimensions in order to stop the chaos. While traveling the dimensions (almost all alternate versions of the past Kamen Rider shows), Decade instead befriends the other Riders and helps them solve potentially world-shaking crises before moving on. In the final arc, the original Riders call Decade to task for not doing his job, and turn on him.
 * Played with, and ultimately subverted, in Fringe. At first, it seems that Walter feels this way about his counterpart when he . Because of our Walter's action, which has also caused fissures in reality and mass casualties in the parallel universe, Walternate felt this way about OUR side, and used his position as Secretary of Defense to prepare for a war with it. Most of the third season is spent with episodes switching between universes, enabling the audience to gain sympathy for the parallel universe while believing that only one universe can survive, until . In the fourth season, Walter's dealing with a lot of guilt over the damage he did to the parallel universe. So, thoroughly subverted in the end.

Toys

 * Bionicle does this when Takanuva ends up in an Alternate Universe rules by a corrupt Empress. That serial featured more on-screen deaths than the rest of the canon combined at the time of writing. It's a partial subversion, since Takanuva is genuinely shocked by some of the things he sees, such as, and he tries to help the people in that universe as well as reaching his own goals of getting home, but after he gets out of there , , he takes only a few moments to wonder about the fate of that universe before continuing on with his quest.
 * Played straight when a bunch of Takanuvas are taken from their original universes, turned evil, and then . Yes, it's a Crowning Moment of Awesome, but when that Fridge Logic hits you, it hits hard.

Video Games

 * Noted in, of all places, Lego Star Wars. "In an infinite universe, all things are possible..."
 * In Star Ocean: The Last Hope, the party accidentally travel to a parallel universe where . The rest of the party plays this trope completely straight, writing off as unimportant since it was just a parallel world that took the damage. However,  himself averts this trope by realising just what he has done, and in response has a Heroic BSOD that lasts for the next ten or so hours of the game.
 * The game itself plays this straight, as no matter what the characters' opinions are, the event has no importance to the plot besides making Edge angst.
 * Lampshaded in Ben There, Dan That!, when Ben remarks that he doesn't need to worry about disposing of anyone's corpse, since he's in a parallel dimension, and thus none of his actions have any meaning beyond their contribution to the accomplishment of his goals.
 * Averted in Muv-Luv where Takeru cares about his friends no matter what universe they're in.

Web Comics

 * Starslip Crisis has this legendary comic.
 * Interestingly, the Many Worlds interpretation of quantum physics can be interpreted in a way that this is how Star Trek-style transporters work. They kill you here and build a clone out of the atoms that are somewhere else. Normally, quantum physics is interpreted as only having one of each particle, but it could be interpreted as that there's multiple particles, and the alternate universes where two are swapped is just as likely. As such, there's a universe, just as likely as this one, where the atoms you're being built of now made you up before. You're effectively being transported to an alternate universe where your atoms are already there. Alternate you gets transported to this universe by the same method.
 * Also by Kris Straub: In Checkerboard Nightmare, some kind of time-travel mishap flings past-Chex into the present. Upon realizing that the many-worlds hypothesis must be in effect, present-Chex fixes this problem by killing his past self.
 * In Narbonic, a Time Travel device is powered by harnessing all the energy in, and in the process destroying, alternate universes "where they probably don't want to exist as much."
 * Inverted in Goats, when one character discovers that the "simulations" he's been running and deleting are actually real universes (at least as real as the one he lives in, which is also being run on a computer somewhere) being destroyed, and immediately has a Heroic BSOD, moaning that he is the worst mass-murderer in history.
 * Kevin and Kell also played with this trope - with Kevin's sister, Danielle, dying in a Heroic Sacrifice, only to be replaced with her double from the Human world (long story). Most of the main cast knows the truth, but have accepted her as part of the family; even if a few would rather believe that she returned from the dead than she's from another dimension.
 * Averted in the To Save Her spinoff of Pastel Defender Heliotrope; even though there are many, many parallel universes, Altenates of the same character are deliberately treated as separate people, even when the alternate of a dead character steps in as a Suspiciously Similar Substitute of the original.
 * Averted and played straight in Sluggy Freelance. The main characters are surprisingly apathetic when they set up their TV to view alternate universes, and discover most of the Myriad Ways end with one of them causing Armageddon. (It being a filler-guest story made in cut-and-paste style may have had something to do with this.) This is averted like hell, however, during the "Aylee" and "That Which Redeems" arcs, where Torg tries his hardest to save alternate versions of the Sluggyverse; the death of is actually one of the saddest moments in the series, and profoundly affects Torg from there on out. Then again, there was the Punyverse...
 * To be fair,
 * Subverted in General Protection Fault: the rest of the cast thinks Trudy is actually her counterpart from the "Emperor Nick" universe. That Trudy switched with "the real" Trudy, to give the latter a chance at true redemption. (So what they think is a new Trudy is actually still the old Trudy)
 * Homestuck is all over the map with this one.
 * When Karkat realizes that the demon who showed up from another universe and destroyed his game session was actually an alternate-universe version of Jack Noir, the Derse agent who helped him overthrow the Black Queen, Karkat says he feels betrayed even though he knows they're technically separate people.
 * When Dave travels back in time to prevent some bad decisions that doomed his timeline, he gets annoyed at being called "the other Dave" or any implication that he's not "really" Dave. Meanwhile, in the doomed alternate future, the readers actually see his doomed timeline blink out of existence. Rose, at least, survives this event in a fashion by merging with her past self.
 * Later, Aradia pulls the same trick as Dave about a couple hundred times, and ends up with an army of alternates of herself from doomed timelines. The alternates know beforehand that they're doomed to premature death--it's one of the laws governing time travel in paradox space--and they're okay with this because Aradia's completely emotionless. When all of the clones do get slaughtered, her friends don't seem terribly concerned about this, mostly because they have bigger problems to deal with than the philosophical implications of time travel clones.
 * Getting back to Dave: Due to weird time shit, he occasionally encounters corpses of himself from alternate timelines, and he's more creeped out by this than his stoic facade will let him admit. When Terezi tells Dave that he can achieve god-tier power by killing one of his doomed-timeline clones--who, as above, is doomed to die somehow, anyway--Dave refuses to do it. Then Terezi breaks down crying after seeing the doomed Dave die, even though alpha timeline Dave is still alive.
 * When we get a look at the Homestuck afterlife, we see that doomed-timeline alternates--Dave, Aradia, and even a doomed John--are also there, and their souls are separate from their alpha timeline selves.
 * Terezi actually has the power to split timelines, by flipping a coin and placing separate courses of action on either outcome. She was responsible for setting up Dave's scenario of killing himself, as each represented whether she'd assist Dave in reaching the god-tier or not. She later repeats the trick by flipping a coin to decide whether to kill Vriska or not.
 * Although the actual coin flips she does are entirely pointless, as she points out: for the first one, she didn't even look at the result; rather it was Dave's decision of which result counted as "show me now" or "show me later" which split the timeline. In the second case, the coin flip was constant across all timelines, because Vriska manipul8ed the coin to get her preferred outcome. The two timelines were entirely a result of her decision of whether or not to go through with killing Vriska.
 * Final Blasphemy has Jeremy being shown several possible futures the author had planned, some of which had alternate timelines.
 * In Wapsi Square, the plan to save Jin resulted in

Web Original

 * In the Darwin's Soldiers tie-in story Card Of Ten, almost an entire team of anti-matter duplicates of the main characters is killed, but it has no effect on the main storyline.
 * In Ink City, Caroline justifies her decision to help Starscream find a way to destroy Optimus Prime this way. Yes, if they're successful, it puts an entire universe filled with innocents at risk... but it's not her home world that's at stake.

Western Animation
"Narrator: Meanwhile, in Universe A, Hermes A heads towards the sun. ...A."
 * An exception is the Codename: Kids Next Door episode "Operation POOL," where the heroes don't try to just escape the horrible Mirror Universe. They manage to actually make it better.
 * Transformers generally avoids this by being a multiverse rather than a universe, and thus all timelines are valid, and occasionally even have an effect on each other. Time Travel stories generally involve a large tear in the fabric of time and space, and any threat coming through from another universe where things happened differently tends to mean something is terribly, horribly wrong, often to the point of Unicron being involved.
 * In fact, recent Transformers materials have indicated Unicron is a multiversal constant--one of the few things that is unchanged in the entire multiverse. If he is destroyed in one universe, that's fine--he still exists in the others. This doesn't prevent them from messing with each other, though--in Marvel's G1 comic, the Unicron of the Marvel continuity plucked Galvatron from both the future and an alternate universe to serve as his herald--presumably since Megatron, in that reality, was dead, and that Galvatron (and Unicron) had succeeded.
 * And the British comics go further then this by also having another, much stronger, Galvatron from a different future who came back in time to kill Unicron. He abandons this plan when he accidentally changes history and realizes that, since he continued to exist, he was just in an alternate timeline. This is a slight justification to Galvatron not caring about the fate of a universe that wasn't his own though; he's a bit of a jerk and more than a bit mad.
 * Futurama plays with this trope in one episode. When the Planet Express crew arrives in an alternate, palette swapped universe, they argue with their counterparts over whose universe is Universe A. ("Why do we have to be 'B'?" "This place kinda feels like a B...") Eventually they decide on the names Universe A and Universe 1. Also of note is that both Benders genuinely care about their perpendicular universe counterparts, because if there's one thing Bender loves, it's Bender.

"J'onn J'onzz: You understand that if we do change the past, you -- this version of you -- will never have existed? Alternate Batman: Nothing would make me happier."
 * In Bender's Big Score, Professor Farnsworth and the Harlem Globetrotters discover a law of physics detailing how the universe protects itself from time paradoxes: It arbitrarily kills any clones created via Time Travel. This happens several times over the course of the film; some clones are mourned more than others.
 * In "The Late Phillip J. Fry" a time machine that can only go forward in time takes Fry, Bender, and the Professor further and further into the future, until the universe they knew dies out and a new universe, completely identical to the old one, comes into being. They consider this a completely acceptable substitute for the real thing. Expendable Clone does come into play, though.
 * There is also an episode where the crew takes Fry on a tour of the Universe and its tourist attractions. One is a scenic outlook to a parallel universe. The difference? Everyone in the parallel universe is wearing cowboy hats. When Fry asks about there being an infinite numbers of these parallels, he is told that there is in fact only one parallel to their own. His response is that's probably enough. It's also why the alternate universes mentioned above are referred to as "perpendicular" rather than parallel.
 * Justice League had an inverted version of this: in an alternate universe where Lex Luthor kills The Flash, Superman returns the favor, and the Justice League becomes the "Justice Lords," a totalitarian force that ensure peace and justice by suppressing dissent and lobotomizing former villains. When they find out about the series' main Earth, they decide to head over, incapacitate the Justice League, and "show them the light". Mind you, the Justice League's response is a pure embodiment of this trope: they depower the Justice Lords and apparently stick them in prisons on the Justice League's Earth. So much for that world. (They still have their Batman, though. They'll be fine.)
 * Averted in the first Season Finale. Before traveling back in time to stop Vandal Savage's plan to Take Over the World the team warn Alternate Batman that:


 * The crowning irony of this statement is that alternate Batman was 'created' by Vandal Savage murdering his parents instead of Joe Chill. How he would feel if he'd known they'd be murdered either way is never revealed, because none of the league have the heart to tell him. On the other hand, Alterbat seems to be saying, "I risk my life every day fighting Alternazis. Death was always a possibility. Go get the bastards!"
 * There's also an episode where Superman is seemingly killed (in fact, thrown into the far future), and without him the Justice League fails to stop another plot by Vandal Savage. Which doesn't turn out the way he plans and instead wipes out nearly all life and hideously mutates the rest. Except for Savage himself, who being immortal is unaffected. After centuries in the literal hell on Earth he created, Savage comes to regret his villainy, and teams up with Superman to prevent himself form defeating the Justice League by sending Superman back in time. Once they succeed, the heroic Savage fades into nonexistence, assumably leaving only the usual supervillain version. The heroic version of Savage considers that an entirely acceptable sacrifice. Superman doesn't seem to give it much thought at all.
 * In the not-officially-related Justice League Crisis On Two Earths when Batman's Evil Counterpart Owlman learns that every decision creates a new universe.
 * Ignoring the fact that once he shows up there and reintroduces human existence to the apparently-dead world, he vastly increases instability and uncertainty, reintroducing decision and instantly splitting off infinite universes (which he and his bomb then inhabit) in which he succeeds or fails in infinite ways. Batman, too, ignores the fact that any triumph over Owlman is just as meaningless because it happened differently on another world that split off.
 * Fridge Brilliance sets in when Owlman's Last Words ("It doesn't matter") and expression indicate that he knows this, meaning he's succeeded somewhere else.
 * By definition, Owlman couldn't succeed:
 * Alternatively, you could assume Owlman accounted for these objections and that there was something different about Earth-Prime that prevented the normal splintering caused by decisions. In any case, the story overall could be seen as a subversion of the trope because the Justice League (sans Batman) seem to take genuine interest in fixing the alternate world's problems irrespective of it's impact on their own world.
 * In fact this is explicitly stated as being the case, all other worlds split out from Earth Prime. Earth Prime is a "Fixed Point" and obliterating that reality will negate every variant spreading out from it.
 * In the underrated and at-times quite creepy Fox's Peter Pan and the Pirates, one episode has Peter and the gang entering an alternate universe where copies of Peter Pan, Wendy and the Lost Boys are slaves, toiling endlessly to prevent the Corc (their version of the crocodile that Captain Hook and everyone else are afraid of) from awakening. Peter Pan et al have an adventure in this alternate universe, but are unable to save these copies of themselves from their lifetime of misery and slavery. The copies help the originals escape, and that's it.
 * Subverted in Batman the Brave And The Bold: When a Depopulation Bomb threatens to kill all life on Earth, Batman and Red Hood teleport it to another dimension. It turns out that (as in, we find out they already knew) dimension's earth was made up entirely of zombies, so the bomb's explosion was completely harmless.
 * In Megas XLR, Coop ends up in an alternate reality were he destroyed the Glorft, turned evil, conquered the world, and worse, lost his gut and became ripped. In an exception, the real Coop decides to take care of his evil self, only to get Megas destroyed. Instead of simply pressing the Reset Button, 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.
 * Averting this trope seems to be the logic Samurai Jack lives by in his Bad Future. 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 stupid in that he'd negate the Bad Future so he'd never need to save his friends, it may be that he's just too kind to risk that this trope is true. Thus the best option would be to destroy Aku in the future and then return to the past and destroy him there.
 * One episode where he finds a time portal seems to indicate that he eventually will do exactly that; the portal's guardian indicates that only The Chosen One may use the portal and trounces Jack in combat. After Jack has been knocked out, the portal itself tells the guardian not to kill him; he may not be the chosen one, but he will be many years later, when he returns with a beard, a crown, grey hair, and an army of liberated peoples from all over the planet.
 * An interesting idea from the TV special Rudolph's Shiny New Year. Father Time explains that, every New Year's Eve, a new island appears in the Archipeligo of Last Year. On these islands, "time stands still", and the world remains as it did during that year forevermore. Since this is a children's show, we get to see The Theme Park Version of a couple of years (One Million BC is depicted as a paradise of jolly cavemen and singing dinosaurs, 1776 is defined by Independence Day and Ben Franklin, and 1023 is apparantly the year in which all the world's fairy tales took place), but Fridge Logic sets in after that. Think about it; in 1964 The Beatles will never break up, but at the same time the Civil Rights movement will barely get off the ground. In 1944, World War II will wage forever, Pearl Harbor is still in flames, and Hitler will never die. In 2001... need we go on? And there is the implication that all the people on these islands are the same people who actually existed in these time periods, meaning that somewhere out there are multiple versions of you, one for each year of your life, trapped forever in a nebulous 12-month span, never to grow, or learn, or live on. And if you indeed weren't from the real world and merely were a reflection living upon one of the islands, how would you ever know?
