History BadFuture / FanWorks

* ''Fanfic/TheOmnitrixHero'': In the Season 4 two-part premiere "From Time to Time", Flash Sentry is accidentally pulled into the future 20 years from his current date. It initially seem great, including aliens living on Earth with humans, humanity expanding across the universe, lots of advanced technology, and Flash himself having mastered the Omnitrix and hailed as "The Hero of 10,000 Forms". But then Flash sees how bitter and abrasive his future self has become, learns of all the horrible things that have happened to his friends, and finds out it all started on the very day he originally came from with [[spoiler:Shining Armor's death]]. After he returns to the Present, Flash prevents this future from happening by [[spoiler:saving Shining Armor's life]], thus leaving to an uncertain timeline.

** Firstly, it [[ForWantOfANail diverges from]] the {{Canon}}ical series during the Season Four episode "[[Recap/MiraculousLadybugS04E03GangOfSecrets Gang of Secrets]]". When Marinette considers giving up her Guardianship and passing on her Earrings to somebody else, Bunnyx shows up to dissuade her... but [[LooseLips accidentally reveals]] that things will be getting ''much worse'' when she [[spoiler:accidentally name-drops Monarch]]. Upon learning what that means, Marinette sets out to prevent that from happening -- and ''succeeds'', with Future!Alix trying to MakeWrongWhatOnceWentRight because she [[ItsAllAboutMe wants to ensure she still gets to become Bunnyx]], regardless of how much everyone suffers as a result.

* The Solar Empire in ''Fanfic/TheConversionBureauTheOtherSideOfTheSpectrum'', thanks to that MirrorUniverse's Celestia deciding to convert all humans into [[TechnicallyLivingZombie newfoals]] after promoting herself to [[GodSaveUsFromTheQueen queen]], Luna is petrified, the main characters are [[spoiler: BrainwashedAndCrazy]] xenophobic fanatics, Equestria is an Orwellian nightmare that's overpopulated, polluted, and drowning under the swell of newfoal immigrants, and literally every good thing about the land is slowly and systematically being stripped away. [[ForWantOfANail The reason for all this?]] Because [[spoiler:TCB!Lyra Heartstrings decided to go on a little scuba diving trip and uncovered an ArtifactOfDoom that craving revenge against ponykind and humanity because a group of ponies and a [[WesternAnimation/MyLittlePonyTVSpecials little girl named Megan]] defeated its maker over a thousand years ago]].

* ''Fanfic/TheBridge'' eventually delves into this, albeit one we just hear about, rather than seeing for ourselves: [[spoiler: at some point, both [[OmnicidalManiac Bagan]] and [[GodOfEvil Grogar]] escape their [[SealedEvilInACan prisons]]; while Equestria and Terra both survive the resultant war, they are heavily devastated, with (among many others) Shining Armor and Cadence killed]]. We don't get much detail beyond that, [[TakeOurWordForIt it's bad enough that]] [[spoiler: Flurry Heart ends up traveling back in time in an attempt to subtly SetRightWhatOnceWentWrong]].

* ''Fanfic/CrossoverChaos'': There's more then one of these in Crossover Chaos. The most well-known one was from v1, where a big war breaks out, killing millions of people. Killer actually DIES and then gets revived [[spoiler: without his immortality, leading him to age like a normal person]], Hawkeye turns into a full on robot, [[spoiler: and becomes completely emotionless]], BJ goes completely insane, Klinger goes blind [[spoiler: but still manages to be badass]], and WordOfGod says [[spoiler: Equestria is gone, and everyone in it DEAD]]. This is what Killer's future self comes to the present to warn his present self about. [[spoiler: There's also ones where Jamie didn't become Supreme God, and it's just about as hellish as you would expect. There's also some good futures, and we've seen some of them. Most of them aren't much better then the bad future.]]
* In chapter 41 of ''Ghosts of the Past'', sequel of ''Fanfic/ChildOfTheStorm'', Harry's shown multiple alternate realities by [[spoiler: an older alternate version of himself who goes by Nathan]] - though they were chosen by Harry's subconscious based on what he subconsciously felt he needed to see - and since he's viewing them from, technically, outside reality, they aren't confined to linear time, meaning that most of them show possible futures. Most of them are fairly pleasant - and sometimes funny. Most, however, is not all. One, shows Harry locked in a brutal duel with an unidentified figure in a charred, smoke-blackened hellscape, another shows him as a ruthless assassin [[spoiler: in the style of the Red Son]] who'd just systematically murdered his way through the Hellfire Club and is lighting a fire to destroy the evidence, and the last - and by far the worst - shows a version of him [[spoiler: as the Dark Phoenix, far less human than his previous dabbling in that]], sitting on the melted throne of a destroyed Asgard, with the weapons of Asgard and the Avengers (and Carol) lying broken before him, along with what's heavily implied to be the Hulk's ''skull'', while Yggdrasil and the rest of the Nine Realms are burning in the background. And what is he doing? [[LaughingMad Laughing like a maniac.]] And according to WordOfGod, it's because he knows he's being observed by Harry and knows what he's feeling. Harry, unsurprisingly, freaks the hell out.

* ''Fanfic/TheCuttingEdge'': Novu convinces Laurel to go back by showing her flashes of the canon timeline after her death, which, from her perspective, is this. This includes John and Thea leaving the team, Samantha Clayton's death, Quentin's death, Oliver being forced to leave a tearful Felicity to fulfill his own bargain with Novu, and Oliver's death after facing of against the army of Shadow Demons on Earth-38.

* ''[[https://www.fanfiction.net/s/10568721/1/Survival-of-a-Monster Survival of a Monster]]'' has an instance similar to "Pyramids of Mars" (below). The first part takes place on the Moon in 2287 and reveals that because the Doctor didn't fully defeat King Wurzin, the villain in [[https://www.fanfiction.net/s/10348014/1/The-Worm-from-Space The Worm from Space]], Wurzin has used the Tufgup to make an interplanetery empire and is about to attack Earth. [[spoiler:The Doctor is able to avert this by going back to just after he left Wurzin before and making sure they are dead this time.]]

* ''Fanfic/{{Crucible|MassEffect}}'' started when a ship named Ad Astra and the antagonists came from a version of future where everything has gone so much wrong. Jane and Garrus didn't marry due to his shotgun wedding with a racist general's daughter. When they managed to get together again, she was killed, Garrus was forced to abandon their son Gaius to Sidonis. The hybrids were hunted to be war machines or lab rats or slaves by both parents' species and the Quarian. Miranda was tortured to death by Cerberus's remains while Victus was killed in the 2nd Krogan rebellion. Gaius's family was destroyed in the worse way possible. And that was just the short version.

* ''Fanfic/{{Reboot|MiraculousLadybug}}'': At some point Hawk Moth (whom Marinette learns the secret identity of) finally gets the ladybug and cat miraculouses and wishes for the return of his wife, [[BeCarefulWhatYouWishFor setting off a chain reaction]] that leads to TheEndOfTheWorldAsWeKnowIt. It is so serious that Master Fu sends Marinette's soul back in time into her thirteen-year-old self despite how dangerous time magic can be.

** Then it turns out that ''canon itself'' is the result of Future!Alix being a TimeTravelingJerkass who's become obsessed with manipulating events so that [[ShipperWithAnAgenda Marinette and Adrien]] end up together in the end... despite the fact that these efforts have created several ''other'' bad futures, which Future!Alix staunchly refuses to learn anything from.
** One of these bad futures involves Marinette and Adrien getting married, just like Future!Alix wants... but the relationship is AllTakeAndNoGive, with Adrien expecting Marinette to keep not just their failing marriage afloat, but the remnants of his failing company as well. Marinette finally decides enough is enough and divorces him, with both Adrien and Future!Alix DramaticallyMissingThePoint.

* ''[[http://www.fimfiction.net/story/45650/time-waits-for-no-mare Time Waits For No Mare]]'' features Applejack flung about three centuries into one of these by (naturally) a botched spell by Twilight Sparkle. During the interim, Twilight apparently became obsessed with a longevity spell (forbidden because it works proportionately to the amount of magic inside its recipients, so it would inevitably stratify the pony tribes if widely used), [[FaceHeelTurn went mad with magic and/or power (not to mention guilt)]], became an alicorn somehow, [[TakenForGranite petrified Princess Celestia]] (and drove off Luna) when the Princesses tried to dissuade her from casting the longevity spell, [[TheStarscream and took over as Chancellor of Equestria]] (although it is implied there may have been more to her story). [[FromBadToWorse Then the griffons invaded and the zebras started playing both sides against each other.]] The end result: earth ponies herded as slaves by long-lived pegasi, all lorded over by far-longer lived unicorns, all of these mostly stuck in one megacity surrounded by old warzones and balanced on a diplomatic knife's edge between the neighboring griffon and zebra territories.

* ''SPD Psycho'' (which has since vanished from the 'net) is a fic where Grumm (''Series/PowerRangersSPD'') manages to reactivate the Red Psycho Ranger, who hijacks a time machine and travels back to the events of "[[Recap/PowerRangersInSpaceS1E43CountdownToDestructionPart2 Countdown to Destruction]]" while pursued by Jack Landors. When Jack attempts to take Psycho Red back to his time, he unintentionally brings Jason Scott (''Series/MightyMorphinPowerRangers''), Tommy Oliver (''Series/PowerRangersZeo'') and Andros (''Series/PowerRangersInSpace'') to the future with him, creating a timeline where Evil won because Andros wasn't there to kill Zordon. As a result, Jason, Tommy and Andros have to face the Goldar, Zedd and Zhane of this time (Zhane having chosen to side with Astronema rather than resist) while Jack goes after Psycho Red to retrieve the time-travel technology and return the past Rangers to their own time.

* In the ''Fanfic/EmpathTheLuckiestSmurf'' story "Days Of Future Smurfed", Empath receives visions of his future and that of his fellow Smurfs. It starts off good, with Empath and Smurfette getting married and having a child. But from there, things start to deteriorate: first Papa Smurf dies, then Smurfette dies, then only he and Brainy are the last of their generation of Smurfs surviving when the Smurf Village is destroyed by an earthquake and Brainy is swallowed up by the earth, and then Empath is left alone in the Smurf Forest with his great-grandson. By the time it reaches the present time of 2005 (which is when the story begins), the Smurf Forest is nearly devastated, and Empath and his great-grandson end up living within a treestump, foraging what they could from the forest in order to survive.

* Played with in "Fanfic/TheRoadNotTaken", an AUFic of Tropers/StarSword's fanfic series. As discussed in the [[http://sto-forum.perfectworld.com/showthread.php?t=1349241 discussion thread]], things ''are'' slightly worse overall here then in the prime universe (there's a mention that the Battle of Vega Colony ended in the complete destruction of the Starfleet side "because there wasn't a plot-armored player character present", rather than the severe but non-total losses suffered in ''Fanfic/FromBajorToTheBlack''), but Eleya actually seems to be happier as the security chief of Deep Space 9 than as commanding officer of a starship.

* ''Fanfic/TheShapeOfTheNightmareToCome'' manages to do this, incredibly, to the source material, which is already a BadFuture for our entire galaxy. 10,000 years after everything's [[JustBeforeTheEnd already on the verge of collapse]], humanity's primary HopeSpot not only died but was [[CameBackWrong horribly warped]], the BigBad won for awhile, and two more forces merged and ''ate half the galaxy.'' And then the author did a [[Fanfic/TheAgeOfDusk sequel]] for ''that''.

* From ''Fanfic/YoungJusticeDarknessFalls'', Bart Allen travels through time again, only this time, he only jumps 5 years forward in time, leading to a world under the rule of Darkseid. The Earth's people are mostly enslaved, and his rule in enforced by Parademons, Suicide Jockeys, [[spoiler:the Supermartian child of Superboy and Mrs. Martian, and the evil Wally West]]. LaResistance is by necessity a band of teenagers, the Justice League was killed off a few years before, and overall, it's very similar to how Bart's original future was [[spoiler:under the Reach]].

* PlayedWith in ''Fanfic/WeightOffYourShoulder'', which [[ForWantOfANail diverges from]] {{Canon}} during the Season Four episode "[[Recap/MiraculousLadybugS04E03GangOfSecrets Gang of Secrets]]". When Marinette considers giving up her Guardianship and passing the Earrings on to somebody else, Bunnyx shows up to dissuade her... but [[LooseLips accidentally reveals]] that things will be getting ''much worse'' when she [[spoiler:mistakenly refers to Shadow Moth as Monarch]]. Upon learning what that means, Marinette sets out to prevent that from happening -- and ''succeeds'', with Future!Alix trying to MakeWrongWhatOnceWentRight because [[ItsAllAboutMe she wants to ensure she still gets to become a Miraculous Hero]] in the future, regardless of how much everyone suffers as a result.

[[AC: ''Anime/MobileSuitGundamSEED'']]

* ''[[https://www.fanfiction.net/s/14213158/1/Mobile-Suit-Gundam-SEED-Paradox Mobile Suit Gundam SEED Paradox]]'': Almost 76 years after the events of ''Anime/MobileSuitGundamSEEDDestiny'', an [[AIIsACrapshoot artificial intelligence]] called JUNO laid waste on Earth, wiping out almost 98% of the human race and every living creature in the ''universe'', ruling the Earth with an iron fist. So, time travelers are forced to find a way to prevent its uprising. [[Franchise/{{Terminator}} Sounds familiar?]] While there's still opposition against the AI, there are some willingly surrendered their humanity to JUNO, being converted into cyborgs, at the cost of their human souls.]]

[[AC:''Series/{{Arrowverse}}'']]
* ''Fanfic/TheCuttingEdge'': Novu convinces Laurel to go back by showing her flashes of the canon timeline after her death, which, from her perspective, is this. This includes John and Thea leaving the team, Samantha Clayton's death, Quentin's death, Oliver being forced to leave a tearful Felicity to fulfill his own bargain with Novu, and Oliver's death after facing of against the army of Shadow Demons on Earth-38.

[[AC:Crossover]]

* ''Fanfic/RebootMiraculousLadybug'': At some point Hawk Moth (whom Marinette learns the secret identity of) finally gets the ladybug and cat miraculouses and wishes for the return of his wife, [[BeCarefulWhatYouWishFor setting off a chain reaction]] that leads to TheEndOfTheWorldAsWeKnowIt. It is so serious that Master Fu sends Marinette’s soul back in time into her thirteen year-old self despite how dangerous time magic can be.

* [[https://www.fanfiction.net/s/13661381/1/Flashback Flashback]] has the canon plot end in one of those. About 12 years after the canon series started, aliens invaded and did to multiple locations on Earth what the Allies did to Hiroshima and Nagasaki during UsefulNotes/WorldWarII. It was so bad that All for One was a TokenEvilTeammate to the heroes, and Eri ultimately [[MentalTimeTravel sent her consciousness back to her past self's body]], [[DidntSeeThatComing with a second One for All]].

* The ''Fanfic/PonyPOVSeries'' chapter "Epilogue" depicts one of these ruled by [[EvilOverlord Discord]] where the Mane Cast never broke free of his power. Not only are they now his immortal servants, Twilight is now TheDragon and the dead rising from the grave to eat their loved ones happens ''a lot''. That is, before [[HopeSpringsEternal Twilight's hope is restored]] and [[HeelFaceTurn she is redeemed.]]

* Heavily implied for Silver and Blaze in ''Blog/AlwaysHavingJuice''; Blaze specifically states that she was the only source of heat for miles, and the only thing Silver has ever “said” about his situation was a wordless image of him sitting alone in what appears to be a very large bookshelf.

* From ''Fanfic/YoungJusticeDarknessFalls'', Bart Allen travels through time again, only this time, he only jumps 5 years forward in time, leading to a world under the rule of Darkseid. The Earth's people are mostly enslaved, and his rule in enforced by Parademons, Suicide Jockeys, [[spoiler: the Supermartian child of Superboy and Mrs. Martian, and the evil Wally West.]] LaResistance is by necessity a band of teenagers, the Justice League was killed off a few years before, and overall, it's very similar to how Bart's original future was [[spoiler: under the Reach]].

[[AC:Unsorted]]
* ''Fanfic/TwilightThenTwilightNowUniverse'': Equestria succumbs to social ruin after multiple wars against both risen evil forces like Grogar or Discord and amongst themselves. The Alicorns have all been killed except for Cadance, who is now despised as a pariah by the descendants of the fallen Crystal Empire for having left the battlefield due to hearing that her beloved husband Shining Armor was killed. Pony society has fractured into a number of warring splinter-nations, such as the Earth Pony supremacists of Coltonville, who absolutely ''despise'' pegasi and unicorns. [[spoiler:To the point that they amputate the horns and wings of unicorn and pegasus foals born amongst their ranks to "prevent them from growing up to become tyrants".]] Ponies have also become a {{matriarchy}} because a curse on their race makes stallions inherently more aggressive than females, especially when gathered in numbers, to the point that they were so prone to flying into deadly rages that all males are now outcast and compelled to live as wandering nomads, permitted access to female society only in brief periods for mating. [[spoiler:Applejack so hates the current state of Equestria that she actually teams up with a BigBad who offers her a chance to SetRightWhatOnceWentWrong.]]
* In the ''Fanfic/TokimekiPokeLiveAndTwinbee'' story "Prophecy of Failure!?", [[spoiler:the Earth of the 2060s-2070s became a dry, hot desert with the exception of the polar regions and their surrounding tundras which was caused by [[OriginalCharacter Yoko and Ellie]] losing the final battle to Eggman.]]
* The prologue of ''Fanfic/TheWeaverOption'' opens with one for the ''TabletopGame/Warhammer40000'' universe, showing that things CAN get worse than [[CrapsackWorld they already are]]. By the 45th Millennium, the Imperium of Man has nearly fallen to Chaos while the remaining Tyranid Hive Fleets have finally reached the Milky Way galaxy. With every major faction weakened and exhausted from constantly warring with each other, the Tyranids easily overrun the galaxy and devour almost all life. This leads the last surviving Chaos warband to perform a ritual to send a champion into the past with the purpose of better preparing the galaxy for the Tyranids' arrival.
* ''Fanfic/OneHelluvaBrokenDay:'' Loona has a dream in which SCP-990 shows her what the future holds if she and the rest of the I.M.P. crew don't stop SCP-001. [[spoiler: She gets to see Verosika, Vortex, the former's entourage, as well as the I.M.P. crew turned into [[TransformationHorror SCP-001-A]] and it culminates in seeing sunlight from SCP-001 entering Pentagram city via a portal to Hell that turns the demons and damned into more instances of it]]. This very quickly cures her of her JerkAss behavior and lets her and the I.M.P. Crew plan their next move.

* ''Fanfic/RebootMiraculousLadybug'': At some point Hawk Moth (whom Marinette learns the secret identity of) finally gets the ladybug and cat miraculouses and wishes for the return of his wife, [[BeCarefulWhatYouWishFor setting off a chain reaction]] that leads to TheEndOfTheWorldAsWeKnowIt. It is so serious that Master Fu sends Marinette’s soul back in time into her thirteen year-old self despite how dangerous time magic can be.
* ''Fanfic/RobbReturns'': From the point of view of the characters, the canon events of ''Literature/ASongOfIceAndFire'' are one of these, which those in the know work hard to avert. And then there's another one, viewed through dream visions had by several characters, wherein the Others succeed in [[ZombieApocalypse invading and overrunning Westeros]]; understandably, they're working hard to stop this one, too.
* ''Fanfic/TheLegendOfZeldaOcarinaOfTimeDragonRand100'': After Ganondorf takes over, everything in Hyrule gets a lot worse. The Kokiri are enslaved and abducted from their homes, Zora's domain freezes over, the Gorons are being worked to death, Kakariko village is afflicted by a demon known as the Necromancer, and the Gerudo are suffering from the threat of rebellion. Hyrule castle along with Castletown lies in ruins as it is inhabited by monsters and redead. The story hints at other bad futures, in other timelines, including the total destruction of Hyrule.
* [[https://www.fanfiction.net/s/13661381/1/Flashback Flashback]] has the canon plot of ''Anime/MyHeroAcademia'' end in one of those. About 12 years after the canon series started, aliens invaded and did to multiple locations on Earth what the Allies did to Hiroshima and Nagasaki during UsefulNotes/WorldWarII. It was so bad that All for One was a TokenEvilTeammate to the heroes, and Eri ultimately [[MentalTimeTravel sent her consciousness back to her past self's body]], [[DidntSeeThatComing with a second One for All]].

* In the ''Fanfic/EmpathTheLuckiestSmurf'' story "Days Of Future Smurfed", Empath receives visions of his future and that of his fellow Smurfs. It starts off good, with Empath and Smurfette getting married and having a child. But from there, things start to deteriorate: first Papa Smurf dies, then Smurfette dies, then only he and Brainy are the last of their generation of Smurfs surviving when the Smurf Village is destroyed by an earthquake and Brainy is swallowed up by the earth, and then Empath is left alone in the Smurf Forest with his great-grandson. By the time it reaches the present time of 2005 (which is when the story begins), the Smurf Forest is nearly devastated, and Empath and his great-grandson end up living within a treestump, foraging what they could from the forest in order to survive.
* ''Fanfic/TheLoneTraveler'': The title character started his travels when he tried to go back in time and fix the world he was living in. Now he gets sent to various universes to help prevent {{Bad Future}}s.
* ''[[https://www.fanfiction.net/s/7701683/1/End-of-an-Era End of an Era]]'' is set in a Bad Future for ''WesternAnimation/ThomasAndFriends'' where steam engines were made illegal, and the authorities of scrappers and Diesel engines scrap any steam engine they find. The plot focuses on [[OriginalCharacter a tank engine named Johnny]] who is sent to Smokey Valley Railroad (by now the world’s last remaining privately owned railroad) and joins a [[LaResistance resistance]] of surviving steam engines and their crews. Eventually, Johnny is attacked by diesels intent on scrapping him, but he’s saved by an older Thomas, who becomes allies with Johnny and explains that after even the railways on Sodor closed, he was lost during the auction of the Sodor engines and sent to a small railway where he was overworked and abused (while his friends ended up in museums). Thomas managed to escape, but every museum he went to refused to take him in, forcing the Tank Engine to live as a vagabond.
* ''Fanfic/PokemonResetBloodlines'' had one mentioned in Chapter 26: [[spoiler: featuring a Bloodliner War, clashes between Shadow Pokemon, Legendaries, Ultra Beasts, and Mirage Pokemon, and the deaths of several characters. Oddly enough it's noted that this bad future was already averted before Ash ever was told about it.]]
** In the sidestory Red Seven Island Interlude, Red has what it's heavily implied to be an experience in the Dream World, [[spoiler: and arrives in the realm of the Unown, where he gets glimpses of a future where he ended up clashing with Ash in Geosenge Town, heavily implying that he intends to use the Ultimate Weapon to bring someone he cares about BackFromTheDead. Whether this still will come to pass or not, it's uncertain.]]

* ''SPD Psycho'' (which has since vanished from the 'net) is a ''Franchise/PowerRangers'' fic where Grumm (''Series/PowerRangersSPD'') manages to reactivate the Red Psycho Ranger, who hijacks a time machine and travels back to the events of "[[Recap/PowerRangersInSpaceS1E43CountdownToDestructionPart2 Countdown to Destruction]]" while pursued by Jack Landors. When Jack attempts to take Psycho Red back to his time, he unintentionally brings Jason Scott (''Series/MightyMorphinPowerRangers''), Tommy Oliver (''Series/PowerRangersZeo'') and Andros (''Series/PowerRangersInSpace'') to the future with him, creating a timeline where Evil won because Andros wasn't there to kill Zordon. As a result, Jason, Tommy and Andros have to face the Goldar, Zedd and Zhane of this time (Zhane having chosen to side with Astronema rather than resist) while Jack goes after Psycho Red to retrieve the time-travel technology and return the past Rangers to their own time.
* In the distant future of ''Anime/DigimonAdventure02'', the featured OriginalCharacter accidentally released Demon from his prison, which results in the entire Digidestined being KilledOffForReal. The OC decides to travel back in time to the moment he is about to release Demon only for the time machine to malfunction and ended up travelling way too far into the past. His entrance into the past thus begins the plotline of ''Fanfic/Zero2ARevision''.
* Played with in "Fanfic/TheRoadNotTaken", an AUFic of Tropers/StarSword's ''VideoGame/StarTrekOnline'' fanfic series. As discussed in the [[http://sto-forum.perfectworld.com/showthread.php?t=1349241 discussion thread]], things ''are'' slightly worse overall here then in the prime universe (there's a mention that the Battle of Vega Colony ended in the complete destruction of the Starfleet side "because there wasn't a plot-armored player character present", rather than the severe but non-total losses suffered in ''Fanfic/FromBajorToTheBlack''), but Eleya actually seems to be happier as the security chief of Deep Space 9 than as commanding officer of a starship.
* ''Fanfic/TheBridge'' eventually delves into this, albeit one we just hear about, rather than seeing for ourselves: [[spoiler: at some point, both [[OmnicidalManiac Bagan]] and [[GodOfEvil Grogar]] escape their [[SealedEvilInACan prisons]]; while Equestria and Terra both survive the resultant war, they are heavily devastated, with (among many others) Shining Armor and Cadence killed]]. We don't get much detail beyond that, [[TakeOurWordForIt it's bad enough that]] [[spoiler: Flurry Heart ends up traveling back in time in an attempt to subtly SetRightWhatOnceWentWrong]].

* The Literature/HarryPotter fanfic ''Fanfic/BackwardWithPurpose'' starts in one where almost everyone is dead, convincing Harry, Ron, and Ginny to travel back in time to save everyone. Part II has [[spoiler: Albus Potter]] making several jumps into the past for the same reason.

* The Solar Empire in ''Fanfic/TheConversionBureauTheOtherSideOfTheSpectrum'', thanks to that MirrorUniverse's Celestia deciding to convert all humans into [[TechnicallyLivingZombie newfoals]] after promoting herself to [[GodSaveUsFromTheQueen queen]], Luna is petrified, the main characters are [[spoiler: BrainwashedAndCrazy]] xenophobic fanatics, Equestria is an Orwellian nightmare that's overpopulated, polluted, and drowning under the swell of newfoal immigrants, and literally every good thing about the land is slowly and systematically being stripped away. [[ForWantOfANail The reason for all this?]] Because [[spoiler:TCB!Lyra Heartstrings decided to go on a little scuba diving trip and uncovered an ArtifactOfDoom that craving revenge against ponykind and humanity because a group of ponies and a [[WesternAnimation/MyLittlePonyTVSpecials little girl named Megan]] defeated its maker over a thousand years ago]].
* The MLP FanFic ''Fanfic/HarmonyTheory'' takes place in a future where Princess Celestia and Luna are ''dead'', Equestria has been divided into two nations on the brink of war, [[TheMagicGoesAway much of the magic has left the world]] leading to the extinction of many sapient creatures and the surviving ones being severely weakened, an Omnicidal WarGod has returned to '''finish what she started''', and the world is so violent you can get a Cutie Mark in ''killing''.
* "Doctor Who" Fanfic ''[[https://www.fanfiction.net/s/10568721/1/Survival-of-a-Monster Survival of a Monster]]'' has an instance similar to "Pyramids of Mars" (below). The first part takes place on the Moon in 2287 and reveals that because the Doctor didn't fully defeat King Wurzin, the villain in [[https://www.fanfiction.net/s/10348014/1/The-Worm-from-Space The Worm from Space]], Wurzin has used the Tufgup to make an interplanetery empire and is about to attack Earth. [[spoiler:The Doctor is able to avert this by going back to just after he left Wurzin before and making sure they are dead this time.]]
* ''Franchise/MassEffect'' Fanfic ''Fanfic/{{Crucible|MassEffect}}'' started when a ship named Ad Astra and the antagonists came from a version of future where everything has gone so much wrong. Jane and Garrus didn't marry due to his shotgun wedding with a racist general's daughter. When they managed to get together again, she was killed, Garrus was forced to abandon their son Gaius to Sidonis. The hybrids were hunted to be war machines or lab rats or slaves by both parents' species and the Quarian. Miranda was tortured to death by Cerberus's remains while Victus was killed in the 2nd Krogan rebellion. Gaius's family was destroyed in the worse way possible. And that was just the short version.

* In still another ''WesternAnimation/MyLittlePonyFriendshipIsMagic'' example, the fic ''[[http://www.fimfiction.net/story/45650/time-waits-for-no-mare Time Waits For No Mare]]'' features Applejack flung about three centuries into one of these by (naturally) a botched spell by Twilight Sparkle. During the interim, Twilight apparently became obsessed with a longevity spell (forbidden because it works proportionately to the amount of magic inside its recipients, so it would inevitably stratify the pony tribes if widely used), [[FaceHeelTurn went mad with magic and/or power (not to mention guilt)]], became an alicorn somehow, [[TakenForGranite petrified Princess Celestia]] (and drove off Luna) when the Princesses tried to dissuade her from casting the longevity spell, [[TheStarscream and took over as Chancellor of Equestria]] (although it is implied there may have been more to her story). [[FromBadToWorse Then the griffons invaded and the zebras started playing both sides against each other.]] The end result: earth ponies herded as slaves by long-lived pegasi, all lorded over by far-longer lived unicorns, all of these mostly stuck in one megacity surrounded by old warzones and balanced on a diplomatic knife's edge between the neighboring griffon and zebra territories.
* Another [[SeriesHiatus long-delayed]] fic, ''[[http://www.fimfiction.net/story/4140/repercussions Repercussions]]'', involves the Mane 6 using a spell to visit the bodies of their future selves. Again, Twilight has apparently [[spoiler:been re-Discorded and]] assassinated Celestia and Luna before taking over, with Pinkie her [[TheDragon Dragon]] driven [[PsychoForHire insane]] by [[spoiler:the death of her family during the initial rebellion]], Rarity a successful but corrupt fashion superstar who uses Pinkie to eliminate the competition [[spoiler:and somehow helped with the coup]], Rainbow Dash the star of the Wonderbolts but far more of a [[ItsAllAboutMe self-centered]] {{Jerkass}}, and Fluttershy [[spoiler:also having helped kill Celestia in revenge for Angel Bunny dying from an accident with the Princess's chariot]]. (Applejack is relatively normal, and Spike [[spoiler:is the leader of LaResistance]].) [[spoiler:The present ponies become more involved once the spell goes wrong (of course) and materialize in their own bodies.]] It is worth noting that, rather than the direct future of the travelers, this is ''technically'' an alternate universe ala ''Literature/{{Timeline}}'' ([[ShoutOut "quantum foam" and all]]).
* ''Fanfic/PowerRangersMythos'' sees five Rangers from the past taken into the year 2600, where the alien alchemist Avanth has already basically conquered the world and killed the era’s original Rangers; it’s not a total dystopia, but it’s not a positive future.

* ''Fanfic/TheShapeOfTheNightmareToCome'' manages to do this, incredibly, to ''TabletopGame/Warhammer40000'', which is already a BadFuture for our entire galaxy. 10,000 years after everything's [[JustBeforeTheEnd already on the verge of collapse]], humanity's primary HopeSpot not only died but was [[CameBackWrong horribly warped]], the BigBad won for awhile, and two more forces merged and ''ate half the galaxy.'' And then the author did a [[Fanfic/TheAgeOfDusk sequel]] for ''that''.
* ''Fanfic/HumanCuriosity'' has this for ''Webcomic/HetaliaAxisPowers''. Much of the plot takes place in the early 22nd Century where most of the Nations mysteriously vanished a century before.
* ''Fanfic/BadFutureCrusaders'', by ''[=TonicPlotter=]'', adapted from a [[http://astringe.deviantart.com/gallery/41135018 series of images]] by an artist on Website/DeviantArt that were designed to be this trope distilled through a ''WesternAnimation/MyLittlePonyFriendshipIsMagic'' setting -- at some point, Princess Celestia died, followed by Twilight Sparkle and Princess Luna engaging in a fight that [[DoomedHometown destroyed Ponyville]], killing or scattering its inhabitants; the other bearers of the Elements of Harmony are missing, presumed dead; Twilight, now [[GodSaveUsFromTheQueen Queen]], has turned Equestria into a totalitarian PoliceState[=/=][[TheEmpire Empire]]; and formerly sweet and kind characters have grown to be either [[FaceHeelTurn villains]], {{Anti Hero}}es, or have lost everything they care about.
* ''Fanfic/ShadowsAwakening'': The Mirror of Despair traps [[spoiler: Tohru]] in a vision of one of these — the heroes managed to defeat Wong, only for [[EnemyWithin the Queen]] to take [[FallenHero control of Jade]], and use the Shadowkhan to kill the other heroes and take over the world. San Francisco is shown to be in ruins, with the humans there being emotionally broken down slaves, and it's implied it's like this everywhere.
* ''Fanfic/CrossoverChaos'': There's more then one of these in Crossover Chaos. The most well-known one was from v1, where a big war breaks out, killing millions of people. Killer actually DIES and then gets revived [[spoiler: without his immortality, leading him to age like a normal person]], Hawkeye turns into a full on robot, [[spoiler: and becomes completely emotionless]], BJ goes completely insane, Klinger goes blind [[spoiler: but still manages to be badass]], and WordOfGod says [[spoiler: Equestria is gone, and everyone in it DEAD]]. This is what Killer's future self comes to the present to warn his present self about. [[spoiler: There's also ones where Jamie didn't become Supreme God, and it's just about as hellish as you would expect. There's also some good futures, and we've seen some of them. Most of them aren't much better then the bad future.]]
* ''Fanfic/MegaManRecut'' has "Future Shock," which is much darker than the show, with scientists essentially being lobotomized. This also extends to the future versions of Mega Man's family.
* ''Fanfic/HarryPotterAndTheFutureUncertain'': Magic is now a crime against humanity in this world.
* The Literature/HarryPotter fanfic ''Fanfic/BackwardWithPurpose'' starts in one where almost everyone is dead, convincing Harry, Ron, and Ginny to travel back in time to save everyone. Part II has [[spoiler: Albus Potter]] making several jumps into the past for the same reason.
* ''Fanfic/HarryPotterAndTheNightmaresOfFuturesPast'' has a similar "everyone died, let's try again" premise, but with just Harry going back.
* In the ''[[Fanfic/TwilightThenTwilightNowUniverse Firehooves Cycle]]'', the basic premise is that a DarkerAndEdgier take on [[WesternAnimation/MyLittlePony G1]] is actually the far future of [[WesternAnimation/MyLittlePonyFriendshipIsMagic G4]], after a series of {{Gotterdammerung}} events.
* From ''Fanfic/YoungJusticeDarknessFalls'', Bart Allen travels through time again, only this time, he only jumps 5 years forward in time, leading to a world under the rule of Darkseid. The Earth's people are mostly enslaved, and his rule in enforced by Parademons, Suicide Jockeys, [[spoiler: the Supermartian child of Superboy and Mrs. Martian, and the evil Wally West.]] LaResistance is by necessity a band of teenagers, the Justice League was killed off a few years before, and overall, it's very similar to how Bart's original future was [[spoiler: under the Reach]].

[[AC:''Franchise/SonicTheHedgehog'']]
* Heavily implied for Silver and Blaze in ''Blog/AlwaysHavingJuice''; Blaze specifically states that she was the only source of heat for miles, and the only thing Silver has ever “said” about his situation was a wordless image of him sitting alone in what appears to be a very large bookshelf.

[[AC:Unsorted]]
* In chapter 41 of ''Ghosts of the Past'', sequel of ''Fanfic/ChildOfTheStorm'', Harry's shown multiple alternate realities by [[spoiler: an older alternate version of himself who goes by Nathan]] - though they were chosen by Harry's subconscious based on what he subconsciously felt he needed to see - and since he's viewing them from, technically, outside reality, they aren't confined to linear time, meaning that most of them show possible futures. Most of them are fairly pleasant - and sometimes funny. Most, however, is not all. One, shows Harry locked in a brutal duel with an unidentified figure in a charred, smoke-blackened hellscape, another shows him as a ruthless assassin [[spoiler: in the style of the Red Son]] who'd just systematically murdered his way through the Hellfire Club and is lighting a fire to destroy the evidence, and the last - and by far the worst - shows a version of him [[spoiler: as the Dark Phoenix, far less human than his previous dabbling in that]], sitting on the melted throne of a destroyed Asgard, with the weapons of Asgard and the Avengers (and Carol) lying broken before him, along with what's heavily implied to be the Hulk's ''skull'', while Yggdrasil and the rest of the Nine Realms are burning in the background. And what is he doing? [[LaughingMad Laughing like a maniac.]] And according to WordOfGod, it's because he knows he's being observed by Harry and knows what he's feeling. Harry, unsurprisingly, freaks the hell out.
* The comic ''Webcomic/RecallTheTimeOfNoReturn'' has everyone but Twilight travel 1000 years into the future (with some help from the Doctor). In this future, Twilight becomes an Empress and controls everything with an iron hoof after a crimson Changeling invasion [[spoiler:which was actually caused by Zygons]], and we have Spike and one of Twilight's former students leading LaResistance.

* Another fairly common ''WesternAnimation/MyLittlePonyFriendshipIsMagic'' fanfic scenario to set a story in one of these in which the Sonic Rainboom never happened, meaning that the Mane 6 never became friends, most of them are depressed, and Nightmare Moon will probably/already has won.

[[AC:''Franchise/SuperSmashBros'']]
* ''Fanfic/MarioAndLuigiDarkestTimeline'' has this as the main premise, with Mario, Luigi, and Bowser accidentally finding themselves in a future where Bowser has taken over the Mushroom Kingdom and nearly wiped out the Toads.

* ''Fanfic/TheCuttingEdge'': Novu convinces Laurel to go back by showing her flashes of the canon timeline after her death, which, from her perspective, is this. This includes John and Thea leaving the team, Samantha Clayton's death, Quentin's death, Oliver being forced to leave a tearful Felicity to fulfill his own bargain with Novu, and Oliver's death after facing of against the army of Shadow Demons on Earth-38.

* ''Fanfic/MarioAndLuigiDarkestTimeline'' has this as the main premise, with Mario, Luigi, and Bowser accidentally finding themselves in a future where Bowser has taken over the Mushroom Kingdom and nearly wiped out the Toads.

( ''[[https://www.fanfiction.net/s/7701683/1/End-of-an-Era End of an Era]]'' is set in a Bad Future for ''WesternAnimation/ThomasAndFriends'' where steam engines were made illegal, and the authorities of scrappers and Diesel engines scrap any steam engine they find. The plot focuses on [[OriginalCharacter a tank engine named Johnny]] who is sent to Smokey Valley Railroad (by now the world’s last remaining privately owned railroad) and joins a [[LaResistance resistance]] of surviving steam engines and their crews. Eventually, Johnny is attacked by diesels intent on scrapping him, but he’s saved by an older Thomas, who becomes allies with Johnny and explains that after even the railways on Sodor closed, he was lost during the auction of the Sodor engines and sent to a small railway where he was overworked and abused (while his friends ended up in museums). Thomas managed to escape, but every museum he went to refused to take him in, forcing the Tank Engine to live as a vagabond.

* ''Fanfic/TheShapeOfTheNightmareToCome'' manages to do this, incredibly, to ''TabletopGame/Warhammer40000'', which is already a BadFuture for our entire galaxy. 10,000 years after everything's [[JustBeforeTheEnd already on the verge of collapse]], humanity's primary HopeSpot not only died but was [[CameBackWrong horribly warped]], the BigBad won for awhile, and two more forces merged and ''ate half the galaxy.'' And then the author did a [[Fanfic/TheAgeOfDusk sequel]] for ''[[UpToEleven that]]''.

* The Solar Empire ([[FanNickname A.K.A.]] [[Fanfic/TheConversionBureau TCB!Equestria]]) in ''Fanfic/TheConversionBureauTheOtherSideOfTheSpectrum'', thanks to that MirrorUniverse's Celestia deciding to convert all humans into [[TechnicallyLivingZombie newfoals]] after promoting herself to [[GodSaveUsFromTheQueen queen]], Luna is petrified, the main characters are [[spoiler: BrainwashedAndCrazy]] xenophobic fanatics, Equestria is an Orwellian nightmare that's overpopulated, polluted, and drowning under the swell of newfoal immigrants, and literally every good thing about the land is slowly and systematically being stripped away. [[ForWantOfANail The reason for all this?]] Because [[spoiler:TCB!Lyra Heartstrings decided to go on a little scuba diving trip and uncovered an ArtifactOfDoom that craving revenge against ponykind and humanity because a group of ponies and a [[WesternAnimation/MyLittlePonyTVSpecials little girl named Megan]] defeated its maker over a thousand years ago]].
