->''"We are the Abandoned One, born but now to die. Our name is Orphan. By our hand, the world shall know redemption!"''
-->-- '''[[SuicidalCosmicTemperTantrum fal'Cie Orphan]]''', ''VideoGame/FinalFantasyXIII''

Sometimes you get lucky, and the MysteriousWaif you adopted becomes a [[HappilyAdopted well-adjusted and welcome addition]] to the family. Other times...not.

[[JustForFun/HowToStopTheDeusExMachina For the sake of the story]], the young couple will have no idea anything is wrong, but [[TvTropesWillEnhanceYourLife tropers will know]] right away there's something not right with this newcomer. She's a CreepyChild, who looks like she strolled out of the UncannyValley. It's not long before things start going wrong around her. [[EvilDetectingDog Pets start acting up]]. Things go missing. There are [[PyroManiac fires]]. Injuries. [[OminousOwl Nocturnal birds of prey]] show up ''everywhere''.

As if they don't have enough to worry about, the couple's biological child is making up crazy stories about how the orphan is planning to [[AxCrazy kill them all]] in their sleep! [[NotNowKiddo They will be ignored]]. Sometimes one or both of the parents figure it out [[RuleOfDrama at the very last minute]]. Sometimes [[AdultsAreUseless it falls to the children]] to stop her.

Feminine pronouns are used because {{Evil Orphan}}s are - like [[CreepyChild creepy children]] generally - frequently little girls but evil little boys are sometimes used.

The Evil Orphan is the modern-day incarnation of the ChangelingTale. It uses the tried-and-true horror of SubvertedInnocence and the DevilInPlainSight, as there is little that can compare to the fear and revulsion of discovering that [[TheFarmerAndTheViper one has been succoring evil incarnate in one's own home]].

Expect anything of the UngratefulBastard, but be particularly on the lookout for those that [[ChildrenAreInnocent play on her youth]], like the WoundedGazelleGambit. May cause FridgeHorror when the audience wonders [[SelfMadeOrphan just how she became an orphan]] in the first place. Incorporates any and every trope having to do with with {{Creepy Child}}ren. See also EnfantTerrible.

The polar opposite of the HeartwarmingOrphan.


[[folder: Anime & Manga]]
* [[SerialKiller Johan Liebert]] from ''{{Anime/Monster}}'' combines this with WhereIWasBornAndRazed. ''Repeatedly.''
* [[spoiler: Rosemary]] from ''Anime/AshitanoNadja'' [[UsedToBeaSweetKid didn't start]] [[HeartwarmingOrphan as this]], but she got in the role ''very'' quickly after [[spoiler: a major FreakOut caused by seeing that her old friend Nadja was the one living her formerly innocent dream.]]
* While Orochimaru of ''Manga/{{Naruto}}'' didn't defect from Konoha until around 10 years before the start of the story, the Third Hokage noticed there was something unsettling about him after he lost his parents. He largely turned a blind eye to it because of his talent.
* Mukuro from ''Manga/KatekyoHitmanReborn'' is adopted by another family but soon uses the man taking care of him to kill off the entire family.
%%* Dio from ''Manga/JoJosBizarreAdventure'' and Diavolo too.

[[folder: Film]]
* Exploited in ''Film/TheGoodSon'': the evil one is the kid with both parents, but he manipulates the people around to make it look like his innocent, half-orphaned cousin is the bad seed.
* ''Film/TheOmen1976''. The boy Damien is an orphan substituted for the couple's real child, who died shortly after birth.
* The antagonist of ''Film/{{Thor}}'' and ''Film/TheAvengers2012'', Loki, had this trope forced on him, seeing as he was lied to his entire life about his parentage. He didn't become evil until he found out he was adopted.
* The whole point of ''Film/{{Orphan}}''. Although, in a subversion, [[spoiler:it turns out that "Esther" isn't even a child, but an adult woman with a growth disorder.]]
* Played for laughs in ''Film/ProblemChild''. He isn't really evil, just misunderstood and tends to PayEvilUntoEvil.

[[folder: Literature]]
* The novel ''Discworld/{{Hogfather}}'' features [[KnifeNut Mr. Teatime]], who was taken in by the Assassin's Guild after both his parents died suddenly when he was very young. In the words of guildmaster Lord Downey, "[[FridgeHorror In hindsight]], [[SelfMadeOrphan perhaps we should have looked into that a bit more]]."
* ''Literature/HarryPotter'':
** Lord Voldemort was raised in a Muggle orphanage, where he spent his free time bullying the other children in a variety of cruel and magical ways. He later became a SelfMadeOrphan by tracking down and murdering his muggle father and paternal grandparents (and framing his maternal uncle for the deed).
** In Theatre/HarryPotterAndTheCursedChild, [[spoiler: Voldemort's daughter Delphi also qualifies, since she was born shortly before both of her parents (Bellatrix Lestrange was her mother) died.]]
* Heathcliff in ''Literature/WutheringHeights''. His FreudianExcuse is relatively strong, but at any rate, he ends up a usurping beast of pure spite, and his intentions are just that.
* Discussed in ''Literature/ABrothersPrice''. In a case of DeliberateValuesDissonance, adoption is seen as "a hidden evil". When a family commits treason, if it's not believed to be divided then every member down to the youngest is killed to prevent a CycleOfRevenge or YouKilledMyFather situation. There is treason in the book, and while Ren does not want to kill [[spoiler: her five-year-old 'niece' Eldie]], her sister ruthlessly reminds her that none of the child's relatives will take them, and if ''they'' take the child, [[spoiler: Eldie]] will eventually know why their family was killed and turn on them.

[[folder: Live-Action TV]]
* ''Series/LittleHouseOnThePrairie'': Nancy Olesen, given her extreme behavior issues and destructiveness. Although it is possible, even probable that Nancy has some very dark secrets in her past, the main reasons given for her extreme destructive, mean behavior center on her being moved from orphanage to orphanage due to her behavior problems (resulting in an unstable life) and the death of her mother while giving birth to her (a condition that today is known as pre-eclampsia). Indeed, in her first episode, Nancy who deep down likely knows why her mother is not part of her life claims she was [[ParentalAbandonment abandoned by her dear, sweet mother]].
* ''Series/{{CSI}}'' has the very [[CreepyChild Creepy]] and InsufferableGenius Hannah, whose parents have died ([[FridgeHorror the details are never explained]]) by her second appearance. [[spoiler: In her first appearance she gets her brother off a murder charge (albeit an accidental one). In her second she frames him and [[DrivenToSuicide Drives Him To Suicide]] to keep him dependent on her]]. She also {{Breaking Speech}}es Sara, possibly contributing to her decision to [[PutOnABus go on a vacation to the rainforest]].
* ''Series/{{Supernatural}}'' has a young girl in the first season who not only cut the throats of her biological and adoptive families, but made it look like her adoptive father did it. Then she did it to people who owned a painting of her adoptive family.
** Considering how ugly that painting was...And that they knew it has a bad reputation of previously deceased owners...Maybe they had it coming.
* Alexander on ''Series/{{Smallville}}'' is an infant clone of ComicBook/LexLuthor. Tess Mercer hoped that by raising him to be good, she could save him from the Luthor legacy. Unfortunately, Alexander has all of Lex's memories, and is aging very rapidly to boot. As of "Luthor" he's gone AWOL, and is out there, somewhere, plotting revenge on her and Clark. [[spoiler:Eventually inverted, since he ended up losing these memories and becoming ComicBook/{{Superboy}}.]]

[[folder: Video Games]]
* During a questline in ''Videogame/WorldOfWarcraft'' Alliance players encounter Hope Saldean, a friendly young lady who was adopted by the Saldean couple four years earlier. While Hope seemingly spends much of the Westfall-storyline feeding the homeless, a shadowy figure is gathering the old members of the Defias Brotherhood. In the end Hope reveals herself to be [[spoiler:Vanessa Vancleef, the daughter of Defias leader Edwin Vancleef]], who has been secretly plotting against the Kingdom of Stormwind the whole time.
* Whole bunch of them in ''VideoGame/RuleOfRose'', though all have their own FreudianExcuse, and you will end up feeling more pity than loathing for them by the end. [[spoiler:Wendy tops all the others by making the others kill Jennifer's dog, and then setting a serial killer loose on the orphanage. [[LoveMakesYouEvil All because Jennifer didn't love her alone.]]]]
* [[spoiler:Clive]] in ''VideoGame/ProfessorLaytonAndTheUnwoundFuture'', who lost his parents in [[spoiler:a time machine explosion]] 10 years ago, and schemed to take vengeance on the people responsible with the money he inherited from his adoptive mother.
* In ''VideoGame/MissionCritical'', you find TheMole's secret diary, where he explains his reasons for betraying TheAlliance to the [[UnitedNationsIsASuperPower UN]]. His parents were scientists. He and his brother were visiting them at work one day, and a [[GreyGoo batch of nanites]] programmed to clean up oil spills was accidentally let loose, and his parents (or rather, all oils in their bodies) were eaten from inside out right in front of them. From that moment, he decided that the UN was right in limiting technological development.

[[folder: Western Animation]]
* ''WesternAnimation/FamilyGuy'' spoofs this with Stewie's pet turtle.
