->''"I remember being dumbfounded when I read the instruction booklet as a kid, and even now I'm still like, 'What?!' whenever I stop to think that all the bricks and rocks in the game are actually the citizens of the Mushroom Kingdom! Makes me want to never break any of the bricks again…"''
-->-- '''Clyde Mandelin''' of "[[http://legendsoflocalization.com/super-mario-bros/manuals/ Legends of Localization]]" on ''VideoGame/SuperMarioBros1''

Backstory Horror is when something that seems harmless or is marketed as harmless has something horrible embedded in the {{backstory}}, either by WordOfGod or AllThereInTheManual. It's a fully intentional hidden well of NightmareFuel on the part of the creators, almost like a creepy EasterEgg for the fans.

Unlike FridgeHorror, which is made up of the audience extrapolating horrible things from given evidence without any confirmation from the creators, in Backstory Horror the creators have said it themselves and the horror is an (at times neglected) part of {{Canon}}. This trope is not founded on implications or {{Fanon}} and doesn't require any extra thought to "get"; all the horror is right there in black and white via WordOfGod.

For example, let's say we have a story about fluffy bunnies, the story sets them out as being cute and cuddly good guys. If the author's website explicitly states that the reason there are no guinea pigs running round is that the bunnies rounded them up and murdered them as a form of "cleansing" - it's this trope. The creators came out and said it, and it's all out in the open for those who feel like reading; no extra thought is needed to figure it out. If, on the other hand, you read the bunny story and later realize (without WordOfGod saying so) that the [[HairRaisingHare bunnies killed all the guinea pigs]], then it is FridgeLogic or Fridge Horror. The creators did not say this happened and the audience may have guessed wrong. It also required extra thought on the part of the audience to figure out.

Backstory Horror can lead to Fridge Horror, but the two are not the same. Related to SurpriseCreepy and CerebusRetcon. Compare and contrast FridgeHorror. Can lead to a CrapsaccharineWorld.

'''Note:''' To be this trope, examples must be canon in some way. {{Fanon}} and dreams generally don't count! If it's implied but not confirmed canon by any source, it's Fridge Logic instead.

!!Works that do this very regularly

[[foldercontrol]]

[[folder:Pokémon]]
!!Franchise/{{Pokemon}}
* Cubone's mother was killed by [[{{Yakuza}} Team Rocket]]. Cubone (originally named 'Orphan', or more accurately, 'Orphon') is portrayed as pining for its mother and wearing her [[http://pokemondb.net/pokedex/cubone skull as a helmet and carries her femur as a club]].
-->"It pines for the mother it will never see again. Seeing a likeness of its mother in the full moon, it cries. The stains on the skull it wears are from its tears. It wears its mother's skull, never revealing its true face."
* Mewtwo is well known as the victim of "years of horrific gene splicing".
* Gengar [[http://www.comicsalliance.com/2011/03/15/weirdest-pokemon-black-white/who steals the life out of people]]
** Gengar's pre-evolved form Haunter's “tongue is made of gas. If licked, its victim starts shaking constantly until death eventually comes.”
* Lampent swoops in afterwards to steal their soul.
* Duskull, if "it finds bad children who won't listen to their parents, it will spirit them away--or so it's said, and "loves the crying of children."
* Drifloon "tugs on the hands of children to steal them away. It is whispered that any child who mistakes Drifloon for a balloon and holds on to it could wind up missing." It also carries souls away to the underworld, sometimes by accident.
* Shedinja. "It is believed that this Pokémon will steal the spirit of anyone peering into its hollow body from its back." Add to this that in the games, you view your Pokémon from the back...
* [[http://www.gamesradar.com/f/the-most-disturbing-pokemon-of-all-time/a-2010042210464734011 Alakazam]] "Its brain cells multiply continually until it dies. As a result, it remembers everything." In short, they all die of brain hemorrhages if their heads don't explode. [[NightmareRetardant Another way to interpret this]], though, is that it continues to produce neurons throughout its lifespan, like a tree continues to grow throughout its lifespan. The cells keep multiplying, but they aren't necessarily the cause of death.
* Pinsir “grips prey with its pincers until the prey is torn in half. What it can’t tear, it tosses far.”
* Hypno feeds off of nightmares. He has been known to kidnap children and then feed of the nightmares of the children and their parents. There was an episode on this, and a subplot in [[VideoGameRemake HeartGold and SoulSilver]]. You also help a girl who's being kidnapped by a Hypno as part of the Sevii Islands quest in [=FireRed=] and [=LeafGreen=].
* Banette is an abandoned doll that sprung to life. They are not happy they were abandoned.
* The reason Farfetch'd is rare is because people are hunting them to the brink of extinction. Apparently they are really good roasted with leeks.
* Ninetales, while usually gentle, is said to be highly intelligent and vindictive. According to legend, it will place a thousand year curse on anyone who pulls one of its tails as a joke. Another states it can cast a sinister light from its eyes and take [[http://pokemon.wikia.com/wiki/Ninetales control of its foe's mind.]] The "thousand year curse" kicks off the plot of ''VideoGame/PokemonMysteryDungeonRescueTeam'', as well as providing [[spoiler:[[WasOnceAMan Gengar]] and [[TakingTheBullet Gardevoir's]]]] Backstory Horror.
* Yamask are the [[WasOnceAMan spirits of people]], who carry masks which once were their human faces. Sometimes they look at the masks and cry. [[LampshadeHanging Lampshaded]] [[http://awkwardzombie.com/index.php?page=0&comic=041811 here]].

!! Human Characters
* ''Anime/{{Pokemon}}'': James from Team Rocket is an escapee from a GildedCage. Becoming a criminal was his only way out.
* Jessie came from a lower class background where they often time had no money for food... so she and her mom ate snow and pretended like it was delicious...
* Not a human character, but completing the trifecta: Meowth was a normal, feral Meowth. Falling for a pet Meowth, he decided to impress her by learning to speak Human and walk on his hind legs like a human. Unfortunately, she regarded this unpokemon behavior as freakish and unnatural.
* Your conversation with Lt. Surge in ''VideoGame/PokemonRedAndBlue''/''Yellow'' reveals there was a war not long ago and that humans used Pokémon in this war. Yes, ''Pokémon'' is a post-war recovery story.
* ''X and Y'' have a war in the backstory that factors heavily into the plot. The war led to the creation of the Ultimate Weapon, a machine powered by the life force of Pokemon that can resurrect the dead, make people or Pokemon immortal, or destroy everything. Team Flare wants to use it to wipe out everyone that isn't them and rule as immortal tyrants.

!!Normal Examples:

[[foldercontrol]]

[[folder:Animé and Manga]]
* ''Manga/AttackOnTitan'' eventually reveals that the two special Titans who brought down humanity's outer defence walls [[spoiler:are not only both human, but close friends of the main protagonists]]. This is later followed by the revelation that ALL Titans, including the completely mindless ones who gorge themselves on human flesh, [[spoiler:were originally human beings. And it is heavily implied that humanity's rulers created them intentionally.]]
* ''Anime/MonsterRancher'''s backstory has humans who grew proud and destructive, creating Monsters for anything that would suit their wants. Eventually they created Moo in an attempt to end the last war, which ended up nearly destroying the entire planet until they created the Phoenix to stop him--and what it took to defeat Moo involved destroying virtually everything. Enough humans were left to rebuild civilization, but far less advanced than it had been before.
* ''Anime/KirbyOfTheStars''. Aww, look, it's an AlternateContinuity to those [[SugarBowl sweet little]] [[Franchise/{{Kirby}} games]] that star an [[RidiculouslyCuteCritter adorable hero]] who looks like a [[RealMenWearPink wad of pink chewing gum]]. Sure, those games had [[DemonicPossession some truly]] [[BloodyMurder disturbing]] [[EldritchAbomination final bosses]], but most of them don't exist in the anime. Then you find out that a ''massive'' war took place at some unspecified time before the series began, and the side of good lost. [[HeroOfAnotherStory Meta Knight]] was one of the few survivors[[hottip:*: various others are seen over the course of the series, along with the children of some of his dead buddies]]. His faithful companions [[ThoseTwoGuys Sword and Blade]] had to become bandits to keep from starving to death during said war.
[[/folder]]

[[folder:Comic Books]]
* ''Comicbook/{{Teenage Mutant Ninja Turtles|Mirage}}'': In the original comic they are raised with one purpose: to murder Shredder, which they do in issue one.
* ''ComicBook/TheMask'': In the original comic, the Mask was a psychotic killing machine similar to SelfDemonstrating/TheJoker, but with horrific supernatural powers.
* ''WesternAnimation/CasperTheFriendlyGhost'': Though it is sidestepped by the creators of the original comic and later cartoon, Casper is actually about a dead, lonely and suicidal child. Sidestepped in the movie, where Casper died when he wouldn't come in from sled riding and caught pneumonia and died.
[[/folder]]

[[folder:Fanfiction]]
* In ''Fanfic/EmpathTheLuckiestSmurf'', it's amazing how most of the Smurfs under Papa Smurf's care live happy, carefree lives like in [[WesternAnimation/TheSmurfs the cartoon show]], given that the parents who were the Smurfs of Papa Smurf's generation have all died in ThePlague that is OnlyFatalToAdults back when the Smurfs were just little Smurflings. And of course, there's Papa Smurf subjecting [[spoiler:his only begotten son]] Empath to 150 years of living in Psychelia with a group of xenophobic emotionless telepaths whose leader had {{Mind Rape}}d him as an infant.
[[/folder]]

[[folder:Film - Live Action]]
* One of the more quiet and slow-paced scenes in ''Film/{{Gremlins}}'' has Kate telling Billy just what happened to make her hate Christmas: Her father tried to enter the house's chimney dressed as Santa when she was a kid, but broke his neck in a fall and got stuck. They thought he was missing for a few days, until they smelled something awful in the fireplace. In a horror comedy that already has plenty of NightmareFuel, this scene especially seems to stick with viewers.
[[/folder]]

[[folder:Literature]]
* ''Literature/LandOfOz'':
** The Tin Man lost all his body parts one by one. They were replaced by metal so he could survive long enough to see his love again. By the time he was whole, she had already fallen in love with a man made out of the Tin Man's lost body parts.
** To the shock of many, ''Literature/{{Wicked}}'' with its twisted fantasy dystopia is actually a more faithful adaptation of the original book than [[Film/TheWizardOfOz the 1939 movie]].
[[/folder]]

[[folder:Live-Action TV]]
* In her character profile on NBC's website for ''Series/{{Community}}'', it is stated that [[ButtMonkey Britta]] was molested on her eleventh birthday by a man in a dinosaur costume, and her dad didn't believe her when she told him. This incident has been only vaguely alluded to on the show.
* ''Series/DoctorWho'' is fairly dark but still an idealistic children's show. Some parts of it are unexpectedly horrible:
** The novelisation of "The Time Warrior" initially contained a very detailed and {{Squick}}ily sexual account of how Sontarans reproduce through probic vent fluids, straight from the mind of their creator Robert Holmes. It got cut by the publisher due to being virtually unprintable, although the new series vaguely alludes to it when Strax mentions being so excited that he clogged his probic vent.
** According to the novelisation, the Argolins were a race initially so violent that they were forced to develop a ridiculous and incoherent code of manners chivalry just to give themselves an outlet. The greatest act of chivalry in Argolin culture was a duel in which both participants both hacked bits off their own bodies to death in order to even the odds and then both died of shock and blood loss. What we see of the Argolins in "The Leisure Hive" is from many centuries after this in which they are a dying race.
** The Fifth and Sixth Doctor companion Peri was repeatedly raped by her uncle as a child, who told her it was their secret.
** The novelisation of "The Twin Dilemma" goes into BodyHorror territory about what regeneration actually does to you, through telling the story of a Time Lord who tried to kill himself repeatedly until he regenerated into someone more attractive, with some very unpleasant results.
** The idea in production was that Ace had lost her virginity to Sabalom Glitz at some point during "Dragonfire", alhough this is only implied onscreen. The much darker ExpandedUniverse picks up on this idea and runs with it.
** Vastra is said in supplemental materials to have met Jenny by eating the Chinese gangsters who were about to gang-rape her.
[[/folder]]

[[folder:Video Games]]
* ''VideoGame/{{Portal}}''. On the surface, it's a puzzle game with the player as a tester of a CoolGun. Beneath the layers though shows an incredibly twisted place caused by {{Mad Scientist}}s, the player had her entire life robbed from them, many were murdered ForScience - there's no way of knowing ''how'' many people have died in the facility before you, the entire situation with Cave Johnson, and that the A.I. that guides the player through each test area unfolds throughout the first game as rather homicidal with a fatally cavalier approach to human life. (And this is in the same universe as ''VideoGame/HalfLife'', so all of ''that'' happened too.) This is made more explicit in ''VideoGame/{{Portal 2}}'', balanced by a [[RetCon more wacky view of the Aperture Science backstory,]] but parts of it are even bleaker than the original. Like the fate of [[spoiler:[[BrainUploading poor Caroline,]]]] for an example.
* Invoked in the multiplayer mode of ''VideoGame/AssassinsCreedIII'', which is marketed as a ThisIsReality version of the [[AppliedPhlebotinum Animus Database]] that allows people to relive the past. As the player levels up, they unlock cheesy, happy-go-lucky meta-commercials promoting it; completing difficult challenges, however, unlocks hacked versions, which contain "Erudito" pointing out true motives, hired actors, careful marketing and blatant lies to hide the truths about it.
* ''VideoGame/{{Touhou}}''. The actual narratives (the games and the manga) rarely get worse than a bit morbid, but the backstories and WorldBuilding contain a parade of murder, deception, bigotry, and confusing metaphysics. Of particular note since these two elements are roughly equal in size.
** Gensokyo was created as a FantasticNatureReserve to preserve {{youkai}} from humans' [[ClapYourHandsIfYouBelieve waning belief in the supernatural]] and the impending TheMagicGoesAway. Much of the world was once like Gensokyo, but now aside from a few persistent stragglers all those mystical beings are either extinct, or endangered and confined to one small region.
** Youkai didn't stop [[ToServeMan eating humans]] once the barrier went up, they just had more restrictions on it. Anyone caught outside designated safe areas at night are fair game, as are any humans from outside the barrier, with youkai going on not-infrequent trips to abduct and eat people. Most of the human characters are friends with youkai without this ever being brought up.
** Oni were driven away from the surface and haven't been seen in so long most believe they're extinct. Suika seems like a typical HardDrinkingPartyGirl given her scheme in ''Immaterial and Missing Power'' is to force Gensokyo into an endless kegger, but she's doing so in the hopes she can draw her people out from hiding. Fortunately there are some living in the Underground, Suika reuniting with an old friend in ''Subterranean Animism''.
** Flandre was [[MadwomanInTheAttic isolated in her mansion's basement]] for nearly 500 years due to her sister's fears about [[PersonOfMassDestruction her powers]], but [[CheerfulChild looking at her]] you'd never know it.
** Parsee is a Hashihime, a youkai that is made when her husband left her for another woman, lurking near a bridge and threatening to kill any loving couple that passes if they don't break up immediately (and in some versions of the legend also kills her ex and his new wife). She's treated as a joke by the cast.
** Even in [[FantasticGhetto the Underground]], a place were youkai who are despised by other youkai are sent, there are some who are pariahs. One of them, Koishi, was so impacted by the FantasticRacism inflicted on her because of the fear of her PsychicPowers she permanently closed her third eye, turning her into an EmptyShell with no emotions or thoughts beyond the surface. Again, you wouldn't know it looking at her.
** The backstory of Byakuren and her followers is that they were protecting youkai from human persecution and trying to find a peace between the two groups, and they ended up persecuted themselves and [[SealedGoodInACan sealed in Makai]] for their troubles.
** The backstory of Miko and her followers is them exacerbating a religious war and manipulating the beliefs of the people so they could install themselves as unquestioned immortal rulers of Japan. It's no wonder that Byakuren and Co. are rather unhappy when they get resurrected.
* In ''VideoGame/AWitchsTale'', ''every kingdom'' has a horrific backstory.
** Rem Sacchras was created by Queen Alice to make a seventh kingdom in order to complete the seal on the Eld Witch. But the land was ruled by evil, and to appease the evil being, she chose to sacrifice the younger twin princess from Rem Boreas, and the younger sister's bitterness towards being sacrificed manifested in poison.
** The Eld Witch's daughters wreaked havoc on Rem Boreas, killing the Ice Queen's two daughters in the process. It's treated as a legend, but the shadow blocking the way to the Shadow Lands in Shadow Town speaks of her home freezing over and how the Ice Rune killed her and her sister.
** The Eld Witch ruined Florin, which was then occupied by the Winged. When they began to suffer, they turned their faces to the moon and cried out for help. The residents of the moon kingdom, who also worshipped the moon, sent down plants to soothe the Winged. The Eld Witch succeeded in wiping the Winged out.
** Oceria was a surface kingdom, but got submerged when the Eld Witch's third daughter grew jealous of its magic.
** In Al'Sahra, the Eld Witch's daughters cursed the land to burn forever. The Eld Witch killed Princess Shahrazad the day after she was crowned, and Lyra is tormented with nightmares of what happened.
** Artis fought in the war without magic at all, using machines. They were all turned into scrap, including Dorothy's dear friends.
* Luigi from ''Franchise/SuperMarioBros'' is shown to be a ClassicalAntihero known for being insecure about his relative anonymity compared to his famous brother, and prone to jealousy, cowardice and attention-seeking. However, he's said in supplemental material to have a very dark secret somewhere in his past (said to be the power behind his incredibly odd LimitBreak in ''VideoGame/SuperSmashBros Brawl'' in which he seems to summon a portal to a dark and distorted dimension). Though this may be a case of AmericanKirbyIsHardcore, since this detail isn't mentioned in the European version.
[[/folder]]

[[folder:Webcomics]]
* Grace in ''Webcomic/ElGoonishShive'' is a {{Keet}} [[VoluntaryShapeshifting squirrel-girl]] who was bred as a SuperSoldier and grew up under horrifying conditions. [[TheWoobie Hugs?]]
* Asia Ellis' backstory in ''[[{{Webcomic/morphe}} morphE]]''. Nowhere in the main comic has the subject of [[http://asia-ellis-understoods.tumblr.com/post/46632393343/full-view-here this segment of her personal Ask Blog]] come up. Those who don't follow it would have no idea to the extent of her troubled past.
[[/folder]]

[[folder:Western Animation]]
* ''WesternAnimation/AdventureTime'':
** WordOfGod is that Ooo is AfterTheEnd, a combination of the [[AtomicHate "Mushroom War"]] and [[TheMagicComesBack the return of magic]] killing all humans ([[LastOfHisKind except for Finn]]) and transforming the planet into the weird, wondrous and dangerous place it is now. The show itself heavily implies this through numerous background details and references, until the fifth season premiere "Finn the Human"/"Jake The Dog" finally confirms it, shown in all its gory glory.
** [[DirtyOldMan The Ice King]] is a humorous IneffectualSympatheticVillain, with one of the most tragic, terrifying cases of LossOfIdentity as his origin story. "I Remember You" plays this for all its worth, contrasting his dark backstory with the incompetent clown he has become for full TearJerker effect.
** [[CuteMonsterGirl Marceline]] is a "radical dame who likes to play games" and one of the most well-adjusted characters, and a good contender for having the worst life out of anyone in the show. This includes a monster ([[{{Satan}} literally]]) of a father, a MissingMom, living through the aftermath of aforementioned Mushroom War as a child, losing a ParentalSubstitute, being abused by a BastardBoyfriend, and spending [[ReallySevenHundredYearsOld 1000 years]] with almost no friends until [[AllLovingHero Finn]] came along. On top of that she had a violent falling out with [[WordOfGay her ex-girlfriend]].
* The AnimatedAdaptation of ''Series/{{Alf}}'' is based on Gordon Shumway's life on Melmac. Which exploded. Which means most everybody we see on that show died - including Alf's family. All those wacky surreal adventures ended with a light in the sky. WordOfGod has three of the supporting characters from that show survive, and the premise allows for others. But at least a good portion of them met their fate before the Tanners even found Alf.
* ''Franchise/MyLittlePony'' is no stranger to SurpriseCreepy, but usually keeps things saccharine regardless of the nasty things that have happened in the setting's past.
** ''WesternAnimation/MyLittlePonyAndFriends'' includes the Twinkle-Eyed Ponies, ponies with gems for eyes. Their eyes were almost never mentioned in the show, and were mostly there as an interesting visual and [[MerchandiseDriven to sell the Twinkle-Eyed Pony toy line]]. The [[ComicBook/MyLittlePony comics]] associated with the franchise stated that the Twinkle-Eyed Ponies got their gem eyes because they were enslaved in a gem mine by an evil wizard, where they toiled in the dark for so long that their eyes atrophied. When the wizard was defeated by Applejack smashing his gem throne, the gems of his throne were [[EyeScream embedded into the ponies' eye sockets]], enabling them to see again.
** ''WesternAnimation/MyLittlePonyFriendshipIsMagic'' has shown that the ponies have been on the brink of extinction on numerous occasions. Equestria only exists in the first place because a horde of {{Eldritch Abomination}}s that [[EmotionEater feed on hatred]] devastated the ponies' original home, and almost froze their new home after they followed the ponies. Then [[GodOfEvil Discord]] arrived to cause an [[TheDarkTimes "eternal state of unrest and unhappiness"]], which only stopped when [[GodEmperor the princesses]] arrived to lay the smack down. ''Then'' one of said princesses [[MadGod went mad]] [[GreenEyedMonster with jealousy]] and almost froze Equestria ''again'' by trying to enact TheNightThatNeverEnds. Most of this is used to show how ThePowerOfFriendship can triumph over anything, but it's rather jarring to consider how many potential apocalypses the ponies have narrowly avoided.
** [[ComicBook/MyLittlePonyFriendshipIsMagic The G4 comics]] explore the backstories of many of [[VileVillainSaccharineShow the show's villains]], making them nastier in the process. King Sombra's involves him realising he is an [[HumanoidAbomination Equinoid Abomination]] and deciding ThenLetMeBeEvil and inflicting a horrible AndIMustScream fate on a benevolent queen, and Tirek's involves kidnap and torture. The origin of Chrysalis and the Changelings may be the worst, being essentially a fusion of insects and pony ''corpses''. Also, those swiss cheese-like holes in their bodies on the show? Those are ''scars'' from when Celestia blasted them with magic 1000 years ago.
* ''WesternAnimation/StevenUniverse'' is mostly about Steven going on fun adventures with his [[{{Magitek}} magical]] [[StarfishAliens alien]] [[HasTwoMommies guardians]]. Who are the last survivors of an army that [[EnemyCivilWar rebelled against their homeworld]], their allies either killed or corrupted into the monsters they spend most of the show fighting. And who arrived on Earth in the first place because they were part of an invasion force that planned to [[PlanetLooters devastate Earth in the process of creating new gem armies]]; [[spoiler:Amethyst]] is one of the products of this.
[[/folder]]

[[folder:Music and Bands]]
* {{Steam Powered Giraffe}}, a generally lighthearted act featuring three performing automatons and a steampunk theme, has a shocking amount of this in their history. Even just a cursory glance over their official timeline and backstory reveals BodyHorror, [[AndIMustScream fates worse than death]], the funny robots experiencing the horrors of war first-hand, and the fact that Rabbit's core was once stolen and misused, resulting in an explosion that killed several people... including the descendant of his creator, Peter Walter II, whom Rabbit seemed to regard as a father figure. It is directly stated that this deeply bothers Rabbit, understandably. (It's later stated in his own bio that he spends his free time [[FridgeHorror feeding the ducks in the Walter family cemetery]].)
