What might be considered the inverse of OffingTheOffspring, and is an equally aberrant behavior, is when a character murders their own parents. Any character behaving this way will probably be AxCrazy and/or a PsychoForHire. An [[TheEvilPrince Evil Prince]] can also do that if he's impatient enough. It's the ultimate mark of an EnfantTerrible or AntagonisticOffspring, the end result of a BetrayalByOffspring, and a likely origin of an EvilOrphan.

It can be justified if the parents [[AbusiveParents happen to be abusive]] or cruel mockeries of humanity from beyond the void -- insofar as murder can be, but at least it's then the domain of the [[AntiHero dark and troubled protagonists]]. It's more justifiable if [[EvilMatriarch the parent is an]] [[ArchnemesisDad outright villain]]. In addition, there are also instances where the child either unintentionally killed his parents or something [[FateWorseThanDeath genuinely horrific]] happened to his/her parents that they are forced to kill them. It can also be justifiable if said parent was going to be OffingTheOffspring anyway, and needed to defend him/herself and had no choice.

Contrast with EvenBadMenLoveTheirMamas, which is based on the premise that [[EvenEvilHasStandards no one, no matter how bad, would act this way]]. If it happens before the murderer is born, this is the GrandfatherParadox. If only the father is killed and it's played for drama then it would be {{Patricide}}. If it's the mother that's being killed, which tends to be portrayed as downright self-destructive, that would be {{Matricide}}. The [[UpToEleven extreme version]], where a person kills not just their parents but their entire people or clan is GenocideFromTheInside.

One subversion is to have this happen by accident and/or for the parents' death be ultimately caused by their own actions involving the child. If said parent's child also happens to be a Mook of the parent, it can also overlap into TheDogBitesBack.

[[folder:Anime and Manga]]
* In the ''Franchise/AceAttorney'' manga, in "Turnabout from Heaven," it is thought that Diana killed her [[AbusiveParents abusive father]] by poisoning him with buckwheat flour, but [[spoiler:he accidentally ingested it]].
* ''Manga/ACruelGodReigns'': Jeremy intentionally kills his stepfather Greg via [[spoiler:VehicularSabotage]], but does not intend for his mother, Sandra, to be in the car as well. Oops. Although considering the RapeLeadsToInsanity in this manga, you can't blame Jeremy too much.
* In ''Manga/AshitaNoJoe'', [[spoiler:Ryuhi Kin]] kills his father by accident [[spoiler:when he thought he was a hungry soldier who came to his son to get him food during the Korean War.]] Because of this incident, he developed [[WhyDidItHaveToBeSnakes a fear of blood]].
* ''Manga/AttackOnTitan'' reveals that [[spoiler:Eren devoured his father Grisha the first time he transformed]]. It's a rather heart-breaking subversion, since [[spoiler: Grisha intentionally fed himself to his son so Eren would not only have the Titan's power but the knowledge gained from his massacre of the Reiss family.]]
** Also kind of applies to [[spoiler:Zeke Yeager, Eren's older half-brother who turned in his parents to the military for being part of LaResistance. While Grisha managed to survive after being sent to Paradis Island, his mother Dina (Grisha's first wife) wasn't so lucky.]] He was then raised by his paternal grandparents.
* ''LightNovel/{{Baccano}}'''s Czeslaw Meyer is one in a case of [[TheDogBitesBack The dog biting back]] where he [[spoiler: kills his parental guardian, Fermet by the only means possible for immortals: devouring them]]. Luckily he gets a [[ThrowTheDogABone better replacement eventually]].
* ''{{Manga/Berserk}}'':
** Guts, the aptly-named main character, killed his abusive adoptive father Gambino in self-defense when he went into his tent and tried to murder the kid. Gambino did this because he blamed him for the death of his adoptive mother Shisu, due to a superstitious belief that she died of plague as a result of picking Guts up from beneath his mother's corpse.
** A much abused pre-teen girl named Rosine snapped upon being beaten by her abusive father, activated [[MacGuffin her Behelit]] and sacrificed both of her parents to the Godhand for her wish to become a fairy and escape from her horrid life. This led her to become the local DarkMagicalGirl.
* In ''Manga/{{Bleach}} 466'', Yukio's backstory has him ruining his father's business and driving his and his mom to suicide, as {{revenge}} for their abandonment. Hitsugaya isn't impressed when Yukio tells him. There's a subversion, though: Yukio claims that he did it happily to punish them, but then Hitsugaya realizes that he's not half as remorseless as he believes; when he points it out, Yukio ''starts defending their memories'' instead, which leads to a massive VillainousBreakdown.
* In Anime/BlueCometSPTLayzner, [[spoiler: Ruu-Kain shoots his father Gresco dead while in the middle of a massive FreakOut after learning the truth behind Grados and Earth. He later hides this and arranges a massive military funeral for Gresco.]]
* After Koshaku Chouno became Papillon in ''Manga/BusouRenkin'', he decides to kill everyone in his household - except those that can tell the difference between him and his (already deceased) younger brother Jiro. Nobody succeeds, including his father.
* ''Anime/CodeGeass'':
** [[spoiler:Suzaku]] killed his father, [[spoiler:the Prime Minister of Japan, Genbu Kururugi]], during Japan's war against Britannia. He did this in order to [[spoiler:force Japan to surrender, thus ending the bloodshed of the war and preventing Japan's total destruction, since Genbu actually was ready to [[HonorBeforeReason have Japan destroyed rather than under Britannian rule]]]]. It worked, but the character is so horribly torn by guilt that the incident gives him LaserGuidedAmnesia for ''years''. To make things worse, [[spoiler:it's indicated in some of the background material that if Japan ''had'' fought to the end as Genbu wanted, that ''could'' have bought enough time for the Chinese Federation and/or the [=EU=] to intervene on Japan's behalf]]. No wonder the culprit [[spoiler: grew into such a DeathSeeker.]]
** In R2 episode 21, [[spoiler:Lelouch killed his father ''and mother'' (after spending 90% of the series trying to find out who [[OnlyMostlyDead killed]] her). They were trying to bring about [[AssimilationPlot the end of the world]] at the time, though.]]
** In the light novels, it's mentioned that [[spoiler:BloodKnight Luciano Bradley killed his abusive father at a very young age.]]
* ''Anime/TheDaggerOfKamui'' starts with a tragic variation: TheProtagonist, Jiro, is framed for the murder of his adoptive mother and sister, and forced to flee [[TorchesAndPitchforks mob justice]]. He's rescued by a passing monk, Tenkai, who offers Jiro the chance to take revenge on the {{ninja}} who killed them. This ninja is actually Jiro's DisappearedDad, who had rebelled against his former master. Tenkai had arranged the murder both as a trap for the rogue, and as the opening act in a GambitRoulette revolving around making Jiro into a {{Tykebomb}} to discover the secrets that died with his father.
* ''Manga/FairyTail'': [[spoiler:Sting and Rogue "killed" the dragons that raised them.]]
* At the end of ''Anime/FullmetalAlchemistTheConquerorOfShamballa'', [[spoiler:Envy]] finally killed his father. He had been wanting to do so most of his life.
* ''Manga/TheSeveringCrimeEdge'': Yamane killed her and Houko's parents due to being influenced by by the spirit of her killing goods' original author. Houko decided to take the blame for it so Yamane wouldn't be burdened with guilt.
* In the ''Manga/DescendantsOfDarkness'' anime, it's revealed that [[spoiler:Muraki's half-brother Saki (who was illegitimate, through Muraki's father) killed his parents and Muraki's mother, and tried to kill Muraki himself before being shot and killed by one of the family's bodyguards]]. The manga has a different, more confusing take on it, [[CutShort which will likely never be resolved.]]
* More than one of these cases show up in ''Manga/DetectiveConan'', one taking almost at the start of the series. [[spoiler: Conan and his friends sneak into an apparently abandoned house, but it turns out that it's still inhabited... by [[MyBelovedSmother an old and desperate woman]] who [[MadwomanIntheAttic keeps his son locked in the basement]] after he snapped on his father fatally during a fight, intending to wait until the StatuteOfLimitations for the crime has passed, even when the son ''does'' and has apparently always wanted to go to jail and atone for his crime. Conan manages to help the poor guy convince his mom to let him go, and they peacefully turn themselves in.]]
* Vital to the plot of ''Anime/LupinIIIVsDetectiveConan'': [[spoiler: Queen Sakura of Vespania is believed to have been accidentally shot to death by her son and heir Prince Gill, [[MurderSuicide who then shot himself in regret.]] In reality Queen Sakura's brother-in-law, [[TheEvilPrince Duke]] [[EvilUncle Gerard]], killed Sakura first and then shot Gill dead [[HeKnowstooMuch after he walked into the crime scene]]...]]
* ''Manga/DragonBall'': Goku killed his [[ParentalSubstitute adoptive grandfather]] Son Gohan through [[AccidentalMurder accidentally]] stepping on him while he was in Oozaru form during the full moon. Being a child ''and'' [[TraumaInducedAmnesia not remembering said incident]], he believes his grandfather died of natural causes. His friends deduce what happened when they see him as an Oozaru, but [[AwfulTruth decide to not tell him]] -- [[spoiler: and neither does Son Gohan himself when they briefly meet, thanks to Uranai Baba]]. Goku only learns the truth when he's an adult already, having learned the story of the Saiyan race from one of the Kaiohs ''and'' having witnessed Vegeta's own transformation into an Oozaru during their fight, and is ''deeply'' unhappy.
* In ''Manga/ElfenLied'', although it's not the case with any of the named Diclonii in the show, most of the diclonii kill their own parents; sometimes from fear, sometimes from the influence of their SuperPoweredEvilSide.
* This is basically what Emiya Kiritsugu did in ''LightNovel/FateZero''. He killed his father and later his surrogate mother, because their deaths potentially prevented the deaths of many more. He began to think that way because his [[ChildhoodFriendRomance friend/love interest]] begged him to kill her before she lost control, which eventually caused a catastrophe, and he couldn't do it.
* Souther from ''Manga/FistOfTheNorthStar'' was tricked into killing his beloved adoptive sifu, as the final stage of his training. This emotional trauma led Souther to swear off love and become a monster.
* ''Manga/FruitsBasket'':
** Tohru Honda originally believes she is this, believing that her not telling her mother Kyouko to come home safe somehow caused her accident[[note]]Though this is more of a NeverGotToSayGoodbye sort of thing[[/note]].
** Kyo Sohma, although his father is still alive, also believes himself to be this, because his curse (of being the Cat) caused his already mentally unstable mother to commit suicide.
* ''Manga/FushigiYuugiGenbuKaiden'' has a prophecy in which [[spoiler: Prince Rimudo aka Uruki]], one of the Genbu Senshi, is fated to kill his [[spoiler: father, Lord Temudan]]. [[spoiler: It's ultimately averted: the prophecy ACTUALLY said "the Emperor will die when the Genbu Senshi are reunited", Uruki ''wanted'' at first to kill his dad [[CruelMercy but decided otherwise]]... and Temudan, who had just been crowned after TheEmperor aka his brother Tegiru and the one who spread such lies was subjected to a CruelAndUnusualDeath, is killed ''by someone else instead'', and in front of Uruki and Takiko. At least Temudan and Uruki manage to make peace before the first's death, however.]]
* ''Manga/FushigiYuugiByakkoIbun'' has a ''very tragic'' version in its first chapter. [[spoiler: A shapeshifting tiger woman was forced to [[GiveHimANormalLife leave the baby girl she had with a human man]] in care of her dad, and ten years later she reappeared as a tigress intending to check on her well-being (and destroy the village if the kid was abused). The little girl, Reipin, had NO idea of this ''and'' had been [[AbusiveParents throughly abused]] by her family, but she met a MagicKnight named Nirusha who [[BecauseYouWereNiceToMe was very kind]] [[IntergenerationalFriendship to her]] and needed to kill a tiger to escape a fatal curse...]] Three guesses as to what happened next. And for worse, [[spoiler: upon hearing her dying tiger mom's FamousLastWords, Reipin stormed into her house and was told the truth... and she [[TheDogBitesBack snapped so badly]] after all the BreakTheCutie that she [[ShapeShifter shifted into her tiger form]] for the first time, [[AssholeVictim killed her father and whole family]], and [[WhereIWasBornAndRazed destroyed the village]].]]
* ''Anime/MobileSuitGundam00'' has two tragic cases:
** [[spoiler:Sohran Ibrahim, the boy who would become Setsuna F. Seiei, the ''lead protagonist himself'',]] shot his parents to death. In his defense, [[spoiler:he and many other kids were brainwashed into doing so by [[BloodKnight Ali Al-Saachez]] to "prove their faith" to a cause Ali himself didn't even believe in]], and it's definitely ''not'' something he's proud of. [[spoiler:One reason he's more or less close to Princess Marina Ismail is because of her similarities to his dead mother.]]
** [[spoiler:Andrei Smirnov of the A-Laws]] [[http://www.youtube.com/watch?v=mVFgWqFWLBU kills his own father]] [[spoiler:Sergei]], under the mistaken impression that he was part of a coup. [[spoiler: He only realised his horrible mistake thanks to a combination of space particles and a pep talk with his adoptive sister Marie.]]
* In ''Manga/HaouAiren'', Hakuron's father was an utter bastard who planned to kill him due to a prophecy. A child Hakuron managed to escape from his dad's grasp (his mother wasn't so lucky), was adopted by a Triad leader, and when he was a teenager he faced his father and killed him himself.
* In ''Anime/HeatGuyJ'', it's revealed that Clair shot [[ArchnemesisDad his father]] [[TheDogBitesBack after]] ''years'' of [[AbusiveParents abuse]], and got a KlingonPromotion to [[TheDon "Vampire"]] out of it. Additionally, his mom [[DeathByChildbirth died giving birth to him]].
* In ''Manga/InuYasha'', young Kohaku is forced to kill his father and other people from his village while BrainwashedAndCrazy, with only his older sister Sango surviving. The trauma of this is later brought up to explain why he [[MoreThanMindControl no longer tries to fight the mind control]] (because that would mean remembering, which is such an horrifying experience for the kid that he'd rather have LaserGuidedAmnesia).
* In ''Manga/JoJosBizarreAdventure'', Dio Brando kills his father Dario with a slow-acting poison, making it look like Dario is dying of a disease. He hated his father for being abusive to his mother, [[EvenBadMenLoveTheirMamas whom he loved dearly.]] He tries to do it again (using the same method, no less!) to his adoptive father George Joestar (for the money), and [[YouMeddlingKids would've gotten away with it too, if it weren't for that meddling Jonathan]]!
** Cars in the second part also...well, forget killing his parents, he killed his clan, save for his ally ACDC and the infant Wham and Santana. On the other hand, they were trying to kill him before he could put his ArtifactOfDoom to use.
** In Steel Ball Run, the AU Dio is a self-made ''widower'', marrying an elderly lady in her eighties before she died six months laters. Unlike that first instance, a lot of people suspect Dio of killing her.
* Tsubasa of ''Manga/KannazukiNoMiko'' killed his abusive father in defense of his younger brother Souma.
* LightNovel/{{Katanagatari}}: [[spoiler: Shichika]] is responsible for killing [[spoiler: both]] his father [[spoiler: and sister, leaving him as the last member of his clan]].
* [[TheEvilPrince Belphegor]] of ''Manga/KatekyoHitmanReborn'' is hinted to have killed his entire family besides just his [[CreepyTwins brother]], though this is only actually mentioned once by Bel himself as an offhand comment to someone whom he was trying to scare.
* In ''LightNovel/TheLegendOfTheLegendaryHeroes'', Lucille kills his parents in order to protect his sister Ferris from them.
* In ''Manga/LudwigKakumei'''s red-riding hood chapter has Lisette, who later goes under the red-riding hood name, kill her two parents after she saw they had gotten money for selling her as a sacrifice to a wolf in the near-by forest. [[spoiler: She actually killed them because they had forced her into prostitution from a young age onward.]]
* Anime/{{Madlax}} has [[spoiler: the main character Margaret, who split herself into her and [[EnemyWithin Madlax]] to kill her beloved but now BrainwashedAndCrazy father, Colonel Richard Burton, in self-defense.]]
* ''Manga/MagiLabyrinthOfMagic'' has [[spoiler: Hakuryuu Ren]], [[spoiler:who killed his mother [[EvilMatriarch Gyokuen]] in order to avenge his brothers, by [[OffWithHisHead beheading her]] with a swift cut of his blade.]]
* Played for tragedy in ''Manga/MahouSenseiNegima''. When the Scottish noblewoman Evangeline [=McDowell=] was turned into a vampire, she ended up slaughtering everyone in her castle in blind blood lust. When she finally came to, everyone was dead and her parents' blood was on her lips. This happened when she was ''ten'', and she's had to live with that guilt for over 600 years.
* In ''Manga/FutureDiary'' [[spoiler:Yuno Gasai's parents [[AbusiveParents kept her locked in a cage and starved her in an attempt to make her into a "perfect" girl.]] Eventually [[TheDogBitesBack she snapped]] and locked them in the same cage until they died of hunger.]]
* In ''Anime/MobileSuitGundam'', [[spoiler: Prince Gihren Zabi becomes TheStarscream and kills his elderly father, Sovereign Degwin, when he was trying to make peace with the Federation. He doesn't get away with it, his EvilGenius sister Kycilia offs ''him'' soon, on the grounds of him being a parricidal murderer who would've been executed anyway.]]
* In ''Anime/{{Monster}}'', Johan kills several sets of adoptive parents from a very young age onwards. [[spoiler: And he kills his sister Anna's adoptive parents, too.]]
* ''Manga/{{Narutaru}}'':
** [[spoiler:[[LonelyRichKid Hiroko "Hiro-chan" Kaizuka]] kills her parents with her newly-acquired {{Mon}} after [[RapeAsDrama certain]] [[BreakTheCutie factors]] drive her to insanity - and said parents' [[AbusiveParents emotional abuse]] (at least from Mr. Kaizuka's side) is just the straw that breaks the camel's back for her.]]
** In the manga only, [[spoiler:it's suggested that [[{{Ubermensch}} Naozumi Sudo]] ''might'' be responsible for the "disappearance" of his parents and older brother, though his true involvement in the matter is left ambiguous]].
** There's also how [[spoiler:Komori]] neglected his sick mother until she ''starved to death'', though after a certain point it's difficult to tell whether he had been doing so for very long before he died.
* ''Manga/{{Naruto}}'':
** Itachi Uchiha killed everyone in his clan except for Sasuke. A bit of a twist, since [[spoiler: he was following the orders of his government to stop the Uchiha from committing a coup d'etat that might have resulted in another devastating world war; in exchange, his superiors agreed to spare Sasuke.]] In fact, Itachi's entire StartOfDarkness flashback from relatively early in the series looks very different after the revelation, when you realize that his emotional rollercoaster and remarks like 'I've given up on this hopeless clan!' aren't actually budding psychosis--[[spoiler: they're a soldier struggling to find sufficient reason to reject unconscionable orders, and ''failing.'']] A later flashback even shows that [[spoiler:he really didn't want to do it, and was ''crying'' as he massacred his family. And Fugaku and Mikoto Uchiha [[FaceDeathWithDignity took their upcoming deaths calmly]], basically telling Itachi "you know, it really sucks that things went like this, but go ahead since you've got orders and there is no other choice for you. We won't hold it against you. And we love you."]]
** A partial example is Haku: His father killed his mother once he found out about their [[SuperpowerfulGenetics bloodline limit]], and when he tried to kill Haku, Haku accidentally killed his father in self-defense out of fear.
** The FillerVillain Shiranami killed his own father in an attempt to obtain the DangerousForbiddenTechnique which his father had been protecting just for the money it could get, and cheerfully boasts about the act.
* ''Anime/{{Noir}}'':
** MafiaPrincess Lady Silvana, aka the Intoccabile, killed her father for violating the Mafia's code of silence, and when she returns from her banishment kills her grandfather (who banished her) as well. These acts cause Silvana to be regarded with awe by the other mafiosi, and professional assassin Mireille Bouquet is terrified of her.
** Mireille killed her uncle Claude, who had been her surrogate father ever since her parents and older brother were killed by [[spoiler:little Kirika]].
** In the final episode, [[spoiler:Kirika]] arguably fits this trope, when [[spoiler:she kills Altena, who is the closest thing to a mother figure that she's ever knowingly had]].
* Two examples in ''Manga/PsychicAcademy'', both of them accidental.
** [[spoiler:Mew]] killed her mother when her parents used her as a guinea pig in an experiment to augment psychic powers, causing her fire aura to go out of control.
** [[spoiler:Ai]] killed both his parents when an accidental usage of the light aura he didn't know he had at the time derailed the train they were riding in.
* ''Manga/RurouniKenshin'':
** [[TheDragon Soujiro Seta]] snapped and killed his whole family (stepmother, half-brothers, younger uncles) when he was a child, [[TheDogBitesBack fed up]] with their [[AbusiveParents horrible abuse]] coming from [[TheUnfavorite his position as an illegitimate son]].
** Also, after [[spoiler:Yukishiro Tomoe's]] death, her ''very'' mentally unstable little brother [[spoiler:Enishi]] is saved by a wealthy Japanese family who find him in near death in Shanghai some time after he fled Japan. He kills them, both for the huge sum of money they had and because he simply couldn't stand anyone having a happy life after losing his own.
* In ''Manga/{{Saiyuki}}'', Gojyo's older half-brother Jien kills his own mother (Gojyo's stepmother) [[AbusiveParents before she can succeed in killing Gojyo]]. Her coercing Jien [[ParentalIncest into sex]] on a regular basis probably had something to do with it, too.
* ''Anime/TalesFromEarthsea'' starts with the main character Arren murdering his father, the king, for no reason other than to steal his MagicSword, leaving his mother a widow.
* Implied of the AxCrazy Chiri Kitsu in one episode of ''Anime/SayonaraZetsubouSensei''. Itoshiki-sensei is killed and she "replaces" him with a small doll to cover up the crime. She quickly becomes paranoid about the rest of the class and they are replaced by dolls as well. While everyone is shown to actually be hiding safely under the school, it makes you wonder when the next scene appears to be Chiri happily telling her parents about her day- and then you see she is addressing dolls...
* One of the arcs in ''Anime/{{Shigofumi}}'' involved a highschool-age girl who had been [[AbusiveParents forced into pornography by her father]]. It's unknown what happened to her [[MissingMom mom]]. But when her dad suggested to her that he wanted to get her little sister into the business, she killed him. You could hardly shed any tears for the dad, though.
* A pretty convoluted case is shown in ''Manga/DetectiveSchoolQ''. [[spoiler:The widow Hanayo Ichinose fakes her death and uses the insurance money to rebuild her business, then gets plastic surgery and tries to get closer to her family (who don't know she's still alive) under the disguise of a PhonyPsychic. Her sons Akihiko and Kunihiko, however, mistakenly think that the strange woman who tries to worm her way in their lives is an accomplice of their [[EvilUncle Evil Aunt]] Sachiyo, a greedy SmugSnake who wants to get the custody of their little sister Kaoru since she's the rightful heiress to what's left of to the family fortune.. so they murder Hanayo without knowing who she really is, [[KnightTemplarBigBrother in a desperate bid to save poor Kaoru from Sachiyo's machinations]]. What follows is [[TearJerker heartbreaking]].]]
* ''Manga/ShouwaGenrokuRakugoShinjuu'' has a very cruel case [[spoiler: where a young Konatsu accidentally was the cause of her parents' deaths, as she unknowingly pushed her mother Miyokichi out of a window and Sukeroku died trying to save her. [[RepressedMemories She can't remember such details, obviously]], and believes that both Miyokichi and Sukeroku fell off in front of her.]]
* In ''Anime/TigerAndBunny,'' [[spoiler:[[VigilanteMan Yuri/Lunatic]]]] began his career by killing his own father, [[spoiler:[[BrokenAce Mr. Legend]]]], [[WifeBasherBasher who was beating up his mom]].
* In ''Manga/TokyoGhoul :Re'', this comes up several times.
** [[spoiler: Seidou Takizawa]] implies during a [[WithGreatPowerComesGreatInsanity kakuja-related]] meltdown that [[MamasBoy he]] was forced to eat his parents during the process of being ReforgedIntoAMinion.
** Saeki aka Torso's StartOfDarkness began when he killed his [[AssholeVictim father]] in a blind rage.
** In a shocking twist, [[spoiler:Tooru Mutsuki]] is revealed to have murdered his family after years of being [[WhyDidYouMakeMeHitYou abused]] [[OffingTheOffspring by his]] [[ParentalIncest father]].
* Tasha Godspell's sister in WitchHunter killed their father soon after awakening as a witch, an event that drove her insane. She also killed Tasha's mentor, who was like another mother to Tasha, in a fit of jealousy.
* In the ''Manga/YuGiOh'' manga, Kaiba [[DrivenToSuicide drove his abusive adopted father to suicide]] after taking over his company.
** Also, what Marik's dark side did to his father.
* Happened to Reiko [[spoiler:(AKA Tetsuo)]] in ''Manga/{{Yuureitou}}''. Two years prior to the series she killed her adopted mother after getting into a fight with her and was DrivenToSuicide, [[spoiler:Or, so everyone thinks. Reiko instead ran off and began [[{{Transgender}} living as a man]].]]
* In ''Manga/OnePiece'', it is eventually revealed that [[spoiler:Donquixote Doflamingo]] killed his father [[CreepyChild at the age of]] ''[[CreepyChild ten]]''. The reason? (It's pretty long) [[spoiler:Since the Donquixote family were World Nobles, they were completely above the law, able to do whatever they wanted, and ridiculously wealthy. However, unlike the other World Nobles who are [[AristocratsAreEvil INSANELY cruel dicks]], Doflamingo's parents were kind and humble, and thus decided to abandon their title to live among the general populace. But because the other World Nobles are so cruel that the citizens rightfully hated their guts to no end, they took out their pain and suffering on the wrong people: the Donquixotes, who just wished to live peacefully. This caused the family to flee the angry mobs of citizens and live in absolute poverty, which lead to Doflamingo's mother's death. The mob eventually caught up with the rest of the family, and tortured them brutally. [[PrincessInRags Doflamingo]], [[CreepyChild already very fucked up]] after the death of [[EvenBadMenLoveTheirMamas his mother]] ''and'' blaming his dad for all the shit the family went through, got so sick of this lifestyle that he killed his father for a (failed) chance to get back to being a World Noble.]]
* It's revealed in ''Manga/TokyoBabylon'' that the [[TheClan Sakurazukamori]] [[spoiler: only consists of one person at any given time since the process of inheriting the title is [[KlingonPromotion killing the predecessor]], usually [[EvenEvilHasLovedOnes the person they love the most]]. As [[TheSociopath Seishirou's]] predecessor was his mother [[YamatoNadeshiko Setsuka]], he killed her: then he held her in his arms as she died and told him that he'd sooner or later be at the receiving end too...]]

[[folder:Comic Books]]
* Narrowly averted with ComicBook/BettyRoss. She almost killed the ComicBook/RedHulk, only to realise he was her father and stop in time.
* Technically, Samaritan from ''ComicBook/AstroCity'' qualifies. He was sent from the future to prevent a disaster that would [[ButterflyEffect cause the end of the world centuries down the line]], but his success meant that his parents never existed.
* in ''[[ComicBook/AvatarTheLastAirbenderThePromise Avatar The Last Airbender The Search]]'', this is the only reason Azula is "helping" Zuko search for their MissingMom Ursa. After her VillainousBreakdown, she blamed all of her problems on an imaginary conspiracy masterminded by Ursa. As long as Ursa is alive, Azula is too afraid to put her plan to [[spoiler:usurp Zuko]] into motion.
* Franchise/{{Batman}}
** Bruce Wayne's childhood friend [[spoiler:Thomas Elliot tried to kill his parents at a young age in order to inherit their riches and because his father was an abusive monster and his mother a simpering money hungry lunatic. He only succeeded in killing his father, and, to avoid suspicion, didn't try again, only truly being orphaned when he smothered his raving senile mother in a fit of anger. This left him with a bitter hatred of Bruce, who tragically lost his parents soon after Tommy tried to kill his]]. Later on in his life, [[spoiler:he joins the Riddler (who discovered that Bruce was Batman]] on a vendetta against him, feeling that, not only did Bruce get the riches [[spoiler:Tommy]] wanted, but that he was wasting those riches as well. Predictably, his vendetta eventually causes him to lose everything and become the full time SuperVillain Hush.
*** In the ''Comicbook/{{New 52}}'' continuity, the exact motivations and sequence of events are a bit different, but the result is the same. [[spoiler: As Bruce became more withdrawn following Thomas and Martha's murder, Tommy killed his parents in the hope that having this in common would let them reconnect. He probably hated them as well, but this seems to have been the primary reason.]]
** Black Mask killed his parents in a fire to inherit their business and fortune. Unfortunately, he was a lousy businessman and when he tried to burn down the factory to cover his tracks, he wound up with the facial injury that gave him his villain name. He was a lot better at being AxCrazy than a businessman anyways.
** In a look at SelfDemonstrating/TheJoker's childhood in ''ComicBook/TheBraveAndTheBold'' revival issue #31, as a child the Joker burned down his house with his bickering parents inside. This being the Joker, [[MultipleChoicePast who knows how accurate the story is]].
** According to ''ComicBook/TheLongHalloween'', Jonathan Crane (the future Scarecrow) killed his mom. [[{{Irony}} On Mother's Day.]]
** And [[spoiler: the Penguin murdered his father (along with his brothers) in the miniseries ''ComicBook/PenguinPainAndPrejudice'' so he could be alone with his mother, the only person who loved him.]]
** A one-off character in the debut issue of ''Gotham Knights'' is a child that kills his parents.
** The ''ComicBook/RedRobin'' villain Wanderer killed her single mother as a child. In this case it seems to be a combination of CameBackWrong and GoneHorriblyRight as she seems to have been a nice enough little girl before falling into the pit of Brazilian Wandering spiders whose deadly venom reacted poorly to her innate healing abilities. It's also not known whether she killed her mother on purpose, though certainly the rest of her numerous murders were intentional.
* Subverted in the Season 9 ''Series/BuffyTheVampireSlayer'' comics. Faith is made so angry that she chokes and almost kills her father, but was stopped by Angel.
* ''ComicBook/BirdsOfPrey'': Misfit is also technically a SelfMadeOrphan, though she did it accidentally. When her apartment building caught on fire she tried to "bounce" away with her mother and little brother. That is how she found out that any living thing she bounces with her ''dies'' en route. She clings desperately to Barbara Gordon and the ComicBook/BirdsOfPrey because she needs both a surrogate mother figure and the opportunity to atone for accidentally killing her family.
* Subverted in ''ComicBook/CableAndDeadpool''. The title characters are at a bar discussing their less-than-stellar childhoods over beer (well, only Deadpool's drinking - Cable's temporarily regressed to his teens). Deadpool's brief flashbacks show his mother's death led to his dad becoming strict bordering on abusive, and he may have shot him. At the end of the issue, we get the full story - it was one of the "wrong crowd" Wade had fallen in with, and he was genuinely horrified.
* Evan [=McCulloch=], the second Mirror Master from ''ComicBook/TheFlash'' series. He was an orphan and end up killing his father by accident in his job as a hit-man. As a result, his mother committed suicide. Another Rogue, Captain Cold, confronted his abusive father but couldn't bring himself to kill the man... so [[KillItWithFire he had Heat Wave do it]].
** Heat Wave himself qualifies, in a sadder way. Murdering them was not the intention, but he set his family home on fire with his parents still inside, his pyromania kicked in completely, and much as he would've wanted to save them he just ''watched''. He couldn't help it.
* ComicBook/{{Hellboy}}'s Liz Sherman became one accidentally, after a SuperpowerMeltdown of hers created a fire that destroyed a city block (among the fatalities were her parents and brother).
* Another rare heroic example: Before Bruce Banner became [[Comicbook/IncredibleHulk the Hulk]], he semi-accidentally killed his abusive father, Brian. In their final confrontation his father was trying to kill him and he had killed Banner's mother, Bruce lashed out as Brian got ready to attack him, sending Brian crashing into the gravestone of Bruce's mother and cracking his skull.
* It's implied in several stories that the ComicBook/PostCrisis ComicBook/LexLuthor murdered his own parents when he was just a child.
* Creator/DCComics' Lobo is not only a self-made orphan, but a self-made LastOfHisKind. As he put it in his appearance on ''WesternAnimation/SupermanTheAnimatedSeries'':
-->"Hah! That's rich. ''I'm'' the last Czarnian. *Aside* I fragged the rest of the planet for my high school science project. [[CrossesTheLineTwice Gave myself an A]]."
* Loki created a StableTimeLoop to ensure his biological parents would die in battle so he would be adopted by the Asgardians.
* The notorious 1954 Creator/ECComics story "The Orphan" (former page image) featured a little girl who kills her abusive father and then frames her neglectful mother and her lover for the murder (resulting in their on-panel execution in the electric chair).
* In the ''[[ComicBook/RomSpaceknight ROM]]'' comic, there was a half-breed offspring of a human and a Dire Wraith, calling itself Hybrid, who was a true monster, murdering both parents by magically 'aging' them and then impaling his father with a pitchfork. It might not be ''entirely'' Hybrid's fault - he was raised by the uber-evil Dire Wraiths, the ultimate form of child abuse. Still, he was as close to pure, self-consciously intentional evil as is likely to be possible.
* Rare heroic example: the ''Comicbook/{{Runaways}}'' were formed when they found out that their parents were a band of supervillains called the Pride, and after initially just trying to avoid their parents, they ended up having to battle them, resulting in the death of all of their parents [[spoiler:and the one member of their own who had remained loyal to the Pride.]] They never actually intended to kill them, but this doesn't stop many people from assuming they did.
* Catman from ComicBook/SecretSix is ''technically'' a Self Made Orphan, although he only shot his mother accidentally because his father pointed the shotgun at her while Thomas was attempting to shoot him. He ''did'' finish the job with a machete in the dad's stomach, though.
* ''ComicBook/ArchieComicsSonicTheHedgehog'':
** It's heavily implied that [[EvilTwin Scourge]] killed his neglectful father Anti-Jules.
** More clearly, Kragok and Lien-Da of the Dark Legion murdered both their father and their stepmother, the former to [[KlingonPromotion become Grandmasters of the Legion]].
* Naturally, a young Emil Burbank (the Lex Luthor AlternateCompanyEquivalent in Creator/{{Marvel|Comics}}'s ''ComicBook/SquadronSupreme''), was also shown killing his parents for the insurance money (from a policy on which he forged their signatures).
* ''ComicBook/{{Supergirl}}'':
** Subverted with Supergirl's enemy Blackstarr, [[ComicBook/Supergirl1982 who kidnapped her mother and considered killing her]], but was stopped by Supergirl before going ahead with the attempt.
** In ''[[ComicBook/Supergirl2005 Day of Dollmaker]]'' villain Dollmaker attempts to murder his father Toyman.
* ComicBook/{{Warlock}} of the ComicBook/NewMutants is a member of the Technarchy, a technological race where being a Self Made Orphan is the standard - adulthood was confered after you killed your "Siredam". Warlock fled because A) his "mutation" was the realization that this was a strange way of doing things and B) the fact that his father, The Magus, can casually ''tear apart suns.''
* Rahne Sinclaire, aka Wolfsbane of ComicBook/XFactor and the ComicBook/XMen, did this to her father, when the brainwashing he had put her under kicked in and caused her to maul him to death before devouring his corpse.
* ComicBook/XMen villain Shinobi Shaw once murdered his supervillain father Sebastian, taking over the Hellfire Club upon doing so. [[DeathIsCheap This being a comic book]] and Sebastian [[JokerImmunity being a long-established villain]], he was eventually revealed to be quite alive and [[OffingTheOffspring not in a good mood with his son]]. Given [[NighInvulnerability Sebastian's powers]], the strangest thing is how long it took for him to come back.
* In ''[[ComicBook/XWingSeries X-Wing: The Phantom Affair]]'', Loka Hask, the AxCrazy psycho who killed Wedge Antilles' parents, comments that Wedge should thank him for it, then goes on to muse that he wishes he had had someone willing to do that for him when he was a boy, but ''no'', he had to do it himself.
* While he has a MultipleChoicePast, one detail that Bullseye keeps bringing up consistently is that he murdered his parents, who were abusive (although the circumstances are sketchy).
** [[spoiler:He offed his dad in ''ComicBook/DarkReign: Hawkeye'', long after he became a supervillain. Not that he didn't try before though.]]
* ComicBook/{{Huntress}} does this when she arranges the murder of her biological father at the end of ''Cry for Blood''. In this case, this was more anti-heroic than outright evil, since her father was a vicious gangster who had ordered the murder of the rest of her family and was trying to blackmail her into joining his gang as an assassin.
* ''ComicBook/JudgeDredd'': Dredd's arch-enemy [[OmnicidalManiac Judge Death]] is revealed in ''Boyhood of a Superfiend'' to have murdered his own family back [[WasOnceAMan when he was still a human being]] known as Sidney De'ath. He first made a failed attempt to kill his sister after she told on him for torturing the family dog. He later reported his misanthropic and serial killing father (whom he considered a role model) to the Judges to further his own career and carried out the execution himself. As a registered Judge years later, he hunted down his mother and sister after they had gone into hiding, shooting his crippled sister in the face and throwing his mother off a cliff.
* [[spoiler:Zodon]] from ''ComicBook/{{PS238}}'' brainwashed his parents and stuck them in an alternate dimension. Even more disturbingly, [[spoiler:he thought he was being ''nice'' by giving them what he thought they wanted]].
* Comicbook/{{X 23}}, after a fashion. She doesn't have parents ''per se'', however she recognizes her creator, Sarah Kinney, as her mother. It's never made completely clear, but some sources and readings suggest that Sarah used her own genetic material to help stabilize the damaged samples (thus why she's the green-eyed UglyGuysHotDaughter, rather than looking more like Comicbook/{{Wolverine}}), and Sarah did serve as a surrogate carrying her to term and giving birth to her, and was also her primary caretaker. Laura killed her against her will when Sarah was contaminated by the trigger scent.
* One of Marvels ''WhatIf'' stories is set TwentyMinutesIntoTheFuture where an aging ComicBook/CaptainAmerica has a final confrontation with a now decrepit and elderly ComicBook/RedSkull, who has kidnapped Cap's wife and children as leverage and trapped them with a bomb connected to a deadmans switch hooked to the Skulls vital signs. He then reveals that during his absence, he has sired and raised a son of his own as the new Red Skull, and when their plan falls apart, the son shoots and kills his father to activate the bomb and distract Cap long enough for him to escape and fight another day. True to form, [[SoProudOfYou the Red Skull is proud of his son for being as ruthless and calculating as him]].
* ''ComicBook/HackSlash'': EvilCripple Courtney in ''Hatchet/Slash''. After ten years of plotting, she murdered her parents so she could inherit their fortune and use it to implement her plan for revenge on the the 'friends' who fled and left her in the hands of a slasher.
* In ''Franchise/AssassinsCreed: The Chain'', Innokenti Orelov ends up having to shoot his own father Nikolai, an Assassin, who is struggling with another Assassin. The bullet passes through Nikolai and the other Assassin, killing both. It's implied Nikolai wanted his son to do this to save himself. Innokenti picks up his father's hidden blade and walks off into the sunset. While his further fate is unknown, it's clear he at least survives to produce a child, as Daniel Cross is his descendant.
* in ''Rat-Man'''s ''Origins Exalogy'' we find the story of Rat-man's childhood and his [[spoiler: step]]father Janus Valker's descend into evil. Particularly, we find out that his father Boda, previous embodyment of the Shadow, was murdered by a hitman sent by Jan's brother Joba.
-->'''Jan''' This is for Boda. For having my father killed.\\
'''Joba''' Hey, don't be mad at me! He was my father, too!
* ''ComicBook/UltimateOrigins'': When Erik's powers came out when he was thirteen, his father tried to kill him with a gun. After realizing what his parents were and had been doing, Erik killed his mother as well.

[[folder:Fan Works]]
* ''Fanfic/ChildrenOfAnElderGod'': [[spoiler:Gendo and Yui used the power of the [[EldritchAbomination Outer Gods]] to create a perfect world.]] However, their stolen power was gradually corrupting that world. When the Children realized what was happening [[spoiler:they rebelled and resolved to destroy the dream world.]] Unfortunately, [[spoiler:Shinji -helped by his teammates- had to kill his mother Yui]] to achieve that goal.
* ''[[Fanfic/TheDarkLordsOfNerima The Dark Lords Ascendant]]'': Zhang is revealed to have killed his father to prevent him from sending an assassin after him when he struck out on his own with some ''very'' dangerous martial arts techniques.
* ''Fanfic/DoingItRightThisTime'': Subverted. After hearing how his father treated Rei, Shinji wants to kill him… and then he thinks of a better idea: giving him exactly what he wants –reunite with Yui- and then watching while his mother gives Gendo a piece of her mind.
* In ''WebVideo/FriendshipIsWitchcraft'' [[spoiler:Fluttershy]] kills her father, who was abusive towards her. He was also a dragon. Apparently dragon genes are recessive, thus why she is a pony.
* [[http://www.fanfiction.net/s/6341291/1/Harveste Harveste]], who was living with abusive relatives after his loving parents died protecting him, killed his legal guardians and his cousin, effectively re-orphaning himself at the age of five.
* ''Fanfic/HigherLearning'': In the original timeline [[spoiler:Asuka got murdered by her own son.]] In turn, [[spoiler:Shinji and Kaoru locked him into what was left of the Geofront. Kaoru]] thinks that his father died down there.
* ''Fanfic/LulusBizarreRebellion'':
** [[spoiler:Shirely]] helped Lelouch kill her father before either of them realized who he was.
** [[spoiler:Kallen]] killed her mother accidentally while trying to stop the uncontrolled stand her mother was powering.
** As in canon, Suzaku [[spoiler: Remembers killing his father. However, the power of Hey Jude reveals that it was actually V.V. and the geass directorate who killed him and altered Suzaku's memories.]]
* Titan from ''Fanfic/MyLittleUnicorn'', who killed his father for more power. [[spoiler:While it is possible he still killed his family, after the rewrite, he just simply killed his entire planet.]]
* In ''Fanfic/TheNorthRemembers'', [[spoiler:Ramsay Bolton, during Stannis Baratheon's attack on Winterfell, finally loses it and kills his father Roose Bolton with his flaying knife.]] He takes him off guard as he's shouting orders to his men, and drags the knife deep down into his spine and through his throat. When the castle explodes, he finds the corpse of his father horribly mutilated from all the rubble, and pees on it as final insult. To most characters, this would be seen as a MoralEventHorizon, but considering how [[spoiler:Roose had betrayed and murdered his own King, desecrating his body with the Freys,]] it's more of a KarmicDeath. [[spoiler:Fat Walda Frey, who is Ramsay's step-mother,]] also meets a gruesome end as [[spoiler:Ramsay]] beats her to death with a jagged rock.
* In ''Fanfic/ThePrayerWarriors'', Literature/{{Percy Jackson|and the Olympians}}, having joined the Prayer Warriors on their quest to kill the Greek Gods, kills Zeus after declaring that he is not his father- God is- in order to avoid committing the sin of patricide. Canonically, Poseidon is Percy's father, but Percy kills him later that chapter, so this still counts any way you look at it. Thalia, Zeus' daughter, helps kill Zeus in a flashback to the retconned version of the scene.
* ''FanFic/SplitSecond'': Sparkle's dark magic killed her parents. This is probably an unintentional example.
* In [[DependingOnTheWriter many]] [[AlternateContinuity canons]] of FanFic/TrollCops, [[spoiler:Tavros]], aka the Nefarious and Notorious Mr. Pupa, did this as the first of his many heinous criminal acts.
* ''Fanfic/SoulEaterTroubledSouls:'' [[spoiler: Bizarrely, Crona is directly responsible for the deaths of both his/her father and mother. Sometime when they were still together, Medusa ordered Crona to kill a certain Evil Human and Ragnarok to eat its soul. After the deed is done, Medusa muses on how “[its] genes helped [her] created the perfect subject,” all but confirming that Medusa made Crona kill his/her biological father. In the third arc, Crona finally achieves payback against Medusa for all the crimes and heinous acts she’s committed to him/her personally and those around him/her.]]
* [[spoiler:Fate does this to Precia]] in ''Fanfic/WhiteDevilOfTheMoon'' after she attacks [[spoiler: Alicia]]. Pretty much no one can blame her at that point.
* In the dark Disney/{{Frozen}} fan song [[http://www.youtube.com/watch?v=78g0SyQjU1s "Will You Help Me Hide a Body?"]], it's revealed that [[spoiler: Anna killed her parents... and intends to come after Elsa next]].
* The unintentional variety occurred in ''[[http://archiveofourown.org/works/9050848 Silver and Gold]]'' when seven-year-old Lily got loose after her first werewolf transformation and killed her parents and older sister.

[[folder:Films -- Animated]]
* Lord Shen in ''WesternAnimation/KungFuPanda2'' is an indirect example. He massacred a village of pandas and was banished by his parents as a result. According to the Soothsayer, the grief of sending him away caused them to [[DeathByDespair die from despair.]]

[[folder:Films -- Live-Action]]
* ''Film/AddamsFamilyValues'' has this in the form of Debbie Jellinsky, the kids' apparent nanny and professional "black widow" style SerialKiller who reveals that her first murders were her parents, [[RantInducingSlight who got her a Malibu Barbie instead of a Ballerina Barbie on her birthday]]: "That's not what I wanted! That's not who I was! I was a ballerina! Graceful! Delicate! They had to go." [[DisproportionateRetribution So she burned the family house down with them inside]].
* Diane in ''Film/AngelFace'', though she only intended to murder her stepmother through VehicularSabotage, and not her father as well.
* Catherine Trammell from the ''Film/BasicInstinct'' movies ''may have'' killed her parents after writing a book detailing her plan to do so, then used, "right, I wrote out this plan for killing my parents, published it in a book, then did it-- I'd have to be crazy to do that" as a defense. Whether she actually did murder her parents or not is not actually stated, though several characters express their opinions that she did.
* Michael Carter, the archvillain of the Aussie horror flick ''Feed'', smothered his obese mother when he was a child. He's locked into a cycle of repeating the same murder as an adult.

* Edmund in ''Film/GermanyYearZero'' poisons his sick father, who is lamenting his uselessness to his family and had previously said he wished he was no longer a burden on his children.
* It's implied Ginger and Brigitte did this to their abusive parents in ''Film/GingerSnapsBackTheBeginning''. When they come upon an outpost, Ginger says that their parents drowned - which is soon revealed to the audience to be bullshit. However, when talking privately with Brigitte, Ginger still alludes to their parents being dead, so one wonders why she had to lie about it before. Add in the casual references to them having been beaten before, and the fact that for some reason, they're traveling on their own during winter at the start of the movie, and the fact that Ginger, at least, always had some sociopathic tendencies, and... Yeah.
* In ''Film/HellraiserIIIHellOnEarth'', Pinhead reveals that Monroe killed his own parents with the same gun he tries to use on the pillarized Pinhead.
* In the second ''Film/TheHumanCentipede'' movie the VillainProtagonist's mom tries to [[OffingTheOffspring kill him]] but he wasn't in his bed at the time. A few minutes later he in turn kills her [[{{Squick}} then]] sets her bashed in corpse at the table and continues his dinner like nothing happened.
* Edgler Vess in the film ''Film/{{Intensity}}'' {{Lampshades}} the FreudianExcuse when he tells the protagonist that his parents were most loving, caring people that he could have ever wanted... but he killed them anyway.
* While he didn't kill them, the titular child character of the movie ''Film/{{Joshua}}'' drove his mother crazy until she was committed and drove his father paranoid until he was arrested, essentially making himself an orphan. All so that he could be adopted by his uncle, who he liked better.
* The Tartutic from Creator/MNightShyamalan's ''Film/LadyInTheWater'' are described as being SO evil that they kill their parents after they're born. ([[FridgeLogic One wonders]] [[{{Headscratchers/Headscratchers}} how the species survives]], if they're that uncooperative.)
* In ''Film/JupiterAscending'', [[spoiler:Balem killed his mother, because she begged him to, likely because she can't stand taking part in the planetary genocides anymore]].
* In ''Film/{{Mikey}}'' the title character murders both sets of adoptive parents he gets.
** As the last set of "parents" he killed weren't his biological parents, either, it's unclear just how many people he's killed...
* The killer in ''Film/{{Mindhunters}}'' when he was just a lad.
* The incomparable ''Film/NaturalBornKillers'' has the female lead helping her badass AntiHero boyfriend kill both her parents, who are admittedly Very Bad People.
* Alluded to in ''Film/RedEye'' when [[Creator/CillianMurphy Jackson Rippner]] is discussing his [[MeaningfulName unfortunate name]]. Whether he is joking or not isn't exactly clear, knowing [[PsychoForHire this fellow]].
-->"That wasn't very nice of your parents."
-->"That's what I told them, before I killed them."
** He also told the female character that he'd never lied to her.... Make of that what you will.
* In ''Film/ScannersIIITheTakeover'', Helena kills her father to take over his pharmaceutical company.
* In the Brian Bosworth movie ''Film/StoneCold'', the villain tells one of his soon-to-be-murder victims:
-->'''Chains:''' You know, at moments like this I think of my father's last words, which were... "Don't, son, that gun is loaded!"
* [[spoiler: Double subverted]] in ''Film/{{Thor}}'' when [[spoiler: Loki kills his biological father Laufey while declaring himself the son of Odin. So it looks like he's going to kill his adoptive father in an attempt to appeal to his biological father, but then he kills his biological father in a (completely misguided) attempt to appeal to his adoptive father. Wow.]]
* Happens more than once in ''Film/VillageOfTheDamned1960''. Specially notorius in the [[Film/VillageOfTheDamned1995 1995 version]], where [[spoiler: Mara, the ringleader of the {{Creepy Child}}ren, first telepathically forces her mother Barbara to put her hand ''inside a boiling pot'', and then uses hee PsychicPowers again to make her throw herself off a cliff.]]
* In the ''Film/{{Wanted}}'' movie, [[spoiler:Wesley unknowingly became one of these, killing his DisappearedDad because the Fraternity used him as an UnwittingPawn -- the one person the rogue assassin who was decimating their ranks could never kill. Naturally, he was told that he was hunting [[YouKilledMyFather the man who killed his father]], instead.]]
* Enforced in ''Film/DeathWarmedUp''. Dr. Howell wants to get rid of his partner Prof. Tucker, whom he sees as an obstacle for his ambitions of creating a way to prolong life. He proceeds to [[{{Brainwashing}} brainwash]] his son (and the film's protagonist) Michael to kill him and his wife. Michael ends up in a mental facility, and Dr. Howell enjoys a productive career.

* In the Film/JamesBond movie ''Film/{{Spectre}}'', it's revealed that 20 years before the events of the movie, [[BigBad Franz Oberhauser]] (a.k.a. [[spoiler:Ernst Stavro Blofeld]]) [[{{Patricide}} killed his father]] out of [[TheResenter resentment]] and [[DrivenByEnvy jealousy]] for favoring Bond over him before faking his own death and forming the titular NebulousEvilOrganisation.

* There's an old Jewish story that's a good way to introduce the concept of chutzpah: a man convicted of murdering his parents begs the court for clemency on the grounds that he's an orphan.
* A little dragon is found, crying. When asked where his mom and dad are, he says he ate them. When asked if he knows what it makes him, he says "Yes (sobs). A complete orphan".

* In the ''Literature/AlexRider'' book ''Eagle Strike'', the villain Damian Cray lost his parents in an accident when a car fell on them from a falling structure. [[MakeItLookLikeAnAccident It wasn't an accident.]]
* ''Literature/ASongOfIceAndFire'':
** [[spoiler:The dwarf Tyrion Lannister]] murders his father [[spoiler:Tywin]], who had always hated him for [[spoiler:being born deformed after his mother died in childbirth]]. It's not just "daddy didn't love me enough", though, [[spoiler:Tywin]] has gone out of his way to be a dick to [[spoiler:Tyrion]] many times, several of which could have gotten the latter "accidentally" killed.
** Although never actually clearly stated outright, quite a few hints are dropped that this is exactly what Gregor Clegane is. And, that it supplies one of the possible reasons why his brother Sandor bailed from the family keep when he did: [[CainAndAbel he saw the writing on the wall]] years before, and took their father's interestingly timed demise as the cue to get packed and seek employment elsewhere.
** [[spoiler:Lord Eon Hunter]]'s sudden death leads people to blame his eldest son, Gilwood, for the murder. He wasn't the culprit, though. All this time, it was [[spoiler:Harlan, the third son]], who might also be planning to [[spoiler:murder his older brothers so he could be Lord of Longbow]].
* In ''Literature/TheBadPlace'', [[spoiler:Frank killed his single biological parent, a hermaphrodite who self-impregnated]]. This provides a major conflict, as a sibling of said Self Made Orphan wishes to avenge that act.
* In ''Literature/BestServedCold'', [[spoiler:Castor Morveer.]]
* By the end of ''[[Literature/BlackLegion The Talon of Horus]]'', [[spoiler:Abaddon]] is one, having killed [[spoiler:the clone of his gene-father, Horus.]]
* ''Franchise/ChildrenOfTheCorn''. [[spoiler:Every single one of 'em.]]
* Strongly implied with Elizabeth Bathory in ''Literature/CountAndCountess''.
* ''Literature/{{Discworld}}:''
** In ''Discworld/{{Hogfather}}'' there is some mystery as to how [[PsychoForHire Jonathan Teatime]] came to be an orphan. While it's not explicitly stated, Lord Downey is quoted as saying "We should have wondered a bit more about that."
** In '''Discworld/InterestingTimes'', it's offhandedly mentioned that Lord Hong's rise to EvilChancellor involved six deaths - the last one being his father. At least he died happy that his son was carrying on a family tradition.
* ''Literature/TheDresdenFiles'': Harry Dresden killed his own foster father and mentor Justin Dumorne. Justified, since Justin was an evil Warlock who tried to enthrall Harry and his foster sister Elaine and had already sicced the Outsider He-Who-Walks-Behind on him. If Harry hadn't killed Justin, Justin would have eventually hunted down Harry and kill/enthralled him. Unfortunately, Harry broke one of the Laws of Magic when he used magic to kill Justin, putting Harry on the White Council's blacklist (he would have been straight up executed if a Councilmember hadn't put his own life on the line for him) and making Harry permanently at risk of falling into TheDarkSide.

* Several instances in the ''Literature/HarryPotter'' series:
** In ''Literature/HarryPotterAndTheGobletOfFire'', we learn that [[spoiler:Voldemort murdered his father and grandparents as soon as he discovered they were Muggles, and not the Wizards he imagined. And that his father abandoned him and his mother while she was pregnant after she stopped feeding him the LovePotion that had kept him there and he came to his senses.]]
** At the end of the same book, we learn that [[spoiler:Barty Crouch Jr. murdered his father. Then [[NightmareFuel transfigured his body into a bone]] and buried it.]] [[spoiler:Barty]] makes much of how both he and [[spoiler:Voldemort]] had very disappointing fathers and the pleasure of killing those fathers. He also seems to regard Voldemort as a father substitute.
** Also, in ''Literature/HarryPotterAndTheDeathlyHallows'' it's revealed that [[spoiler:Ariana Dumbledore accidentally killed her mother Kendra]].
* ''Literature/TheHeroesOfOlympus'':
** This is the reason why Leo is initially afraid of his [[PlayingWithFire fire powers]]: [[spoiler:when he was a kid, [[BigBad Gaia]] visited the workshop where he and his single mother were, with the firm intention of preventing Leo from becoming a powerful enemy; Leo used his powers to try and protect his mother, but lost control and started a fire, accidentally killing her instead. He still has his father, but since he's the god Hephaestus whom Leo only met at 15...]]
** Hazel killed her mother and herself to stop Gaea from raising Alcyoneus back in 1942.
* ''Literature/{{Heroics}}'': [[spoiler: Tess Wechsler]] kills [[spoiler: her father]] in self-defense.
* The AffectionateParody ''Literature/HowToBeASuperhero'' recommends this as a method for becoming a superhero.
-->''Getting Your Parents Shot Dead In Front of Your Eyes''\\
At first, this might seem like a strange tactic, but if it was good enough to start ''[[Franchise/{{Batman}} you know who]]'' on one of the most successful crimefighting careers of all time, then it's certainly an avenue worth exploring!
* Creator/StephenKing's short story "I Know What You Need," although the primary topic of the story is the use of {{telepathy}} for [[QuestionableConsent purposes of seduction]].
* ''Immortal Literature/InDeath'' reveals that Eve Dallas killed her father in self-defense after repeated physical and sexual abuse at his hands.
* Miriamele in ''Literature/MemorySorrowAndThorn'' is forced into this to destroy the EldritchAbomination possessing her father at the end of To Green Angel Tower. Earlier in the series, Benigaris inherits the throne of Nabban by [[UnfriendlyFire stabbing his father in the back]] during the siege of Naglimund.
* In ''Literature/MidnightsChildren'', Zafar kills his father, General Zulfikar, after returning from a border skirmish. Saleem implies it is because he discovered Zulfikar's smuggling operations, but says it's impossible to be certain; the Pakistani government denied the scandal, and Zafar may have had [[AbusiveParents other motives]].
* Crake in ''Literature/OryxAndCrake'' by Margaret Atwood is implied to have killed his uncle and possibly his mother, too (his father was killed (executed) while Crake was still a kid, so this leaves him an orphan).
* Alan Campbell's ''Literature/ScarNight'': [[spoiler:The fallen angel Carnival faces down [[EvilOverlord the god Ulcis]], who turns out to be her father, and kills him in a [[AnticlimaxBoss disappointingly easy fight]].]]

* In ''Literature/ShipBreaker'' Nailer's MissingMom is dead long before the story starts, of an infection. His father, [[ArchnemesisDad Richard]] [[FunctionalAddict Lopez]], on the other hand, is still alive and kicking, [[TheAlcoholic much]] [[TheSociopath to]] [[AxeCrazy everyone's]] [[AbusiveDad regret]]. When Richard takes over as TheHeavy of the novel, it's only a matter of time before he and Nailer end up facing one another. While Nailer doesn't want to fight his dad, Richard has no qualms about OffingTheOffspring, or selling Nailer's friend, [[DistressedDamsel Nita's]] organs to the Life Cult, forcing Nailer to kill him in a KnifeFight.
* In ''Literature/{{Slan}} Hunter'', [[spoiler:Jem Lorry]] murders his father when he learns the truth about his birth, and to ensure that the story will never be revealed.
* In Creator/RayBradbury's short story "The Small Assassin," a baby kills its parents.
* Palpatine was revealed to have murdered his parents and siblings when he was a late teenager in the novel ''Franchise/{{Star Wars|Expanded Universe}}: Literature/DarthPlagueis''. It's also implied that he desired to murder his father, at the very least, ever since he was a baby.
* In ''Literature/TheStormlightArchive'' [[spoiler:Shallan]] killed [[spoiler:her]] father before the series started. In the second book it's revealed that [[spoiler: she killed both her parents. Her mother tried to kill her when she started developing the powers of a Radiant, and she killed her in self defense. Her father allowed others to believe he did it, and became an abusive drunk. She poisoned him after he really did kill his second wife and was beating her brother to death, then strangled him when the poison failed to finish him off.]]
* In ''Literature/TheReader2016'', the final task for the Second to complete before becoming an Assassin is to [[spoiler: find and kill their own parents.]]
* "Literature/TheVeldt": At the end of the story, Peter and Wendy trap their parents in the nursery and have the (holographic) lions eat them.
* Lois Lowry's ''Literature/TheWilloughbys'' has the children encourage their extremely indifferent parents to go on a long vacation, hoping they'll be killed. Turns out later [[spoiler: that's just what happens]] though it takes several attempts. Actually the children themselves don't have to do anything at all; their parents just seem to love taking risky chances.
* Monarchies in ''Literature/WingsOfFire'' require children to kill their parents. A daughter must challenge her mother and [[KlingonPromotion kill her]] to claim her throne. The exception to the rule is the [[spoiler:ActualPacifist [=RainWings=] who have a rotation of queens and have non-violent ways of claiming their mother's thrones.]] The series begins with a twenty year war caused by the last [=SandWing=] queen being killed by a human. This sent [[SuccessionCrisis her four daughters into a war for the throne]], where they got the other dragons involved as well.
* Regent from ''Literature/{{Worm}}'' aspires to this, but since his father is the EmotionEater villain Heartbreaker who enslaves women and forces the children he has by them through TrainingFromHell this is pretty justified.
* ''Literature/VillainsByNecessity'': [[spoiler:Sam]], in the final battle. Though he didn't ''know'' that [[spoiler:Mizzamir]] was his father until minutes before killing him for unrelated reasons.
* In the ''Literature/PreludeToDune'' trilogy, Glossu Rabban ends up killing his father Abulurd for [[spoiler:stealing the spice hidden away by the Baron]], loudly proclaiming himself as "The Beast". Notably, Baron Harkonnen (Abulurd's half-brother) is angry with Rabban not for killing Abulurd but for doing it without the Baron's approval.

* ''Series/{{Angel}}'':
** Treated in a bizarrely humorous way after Wesley shoots his father because his father was threatening Fred [[spoiler: though it was actually a robot shapeshifter. Wesley was sure it was him, though, and that he would really do such a thing]]. Angel tries to comfort him, but [[UnwantedAssistance it doesn't help]]. The characters bring up both Angelus killing his parents as a vampire and Spike killing his mother.
-->'''Angel:''' You know, I killed my father. It was one of the first things I did after becoming a vampire.
-->'''Wesley:''' I hardly see that's the same thing.
-->'''Angel:''' You're right, dunno why I brought it up.
-->'''Spike:''' Heard you offed your dad. You know I killed my mum, well I mean I'd already killed her but then she tried to shag me so I had to ''(mimes staking)''.
-->'''Wesley:''' Thank you, I really don't need any more comforting.
-->''(later, again. Wesley is in his office, Fred walks in)''
-->'''Wesley:''' If you're here to tell me about how you murdered your parents...
-->'''Fred:''' What?
** Fred's parents are both alive, and Wesley knew it perfectly well. Not only that, but they are the best darn parents in Texas, and until [[spoiler: Fred dies]] it's probably the happiest family in the Buffyverse, so the situation is completely unlike Angel, Spike or Wesley.
** Angel: "My parents were great. Tasted a lot like chicken."
* ArrowVerse
** Played with in the backstory of Mick Rory, AKA Heat Wave. His introductory episode in ''Series/TheFlash2014'' explains that his first crime was burning down his house with his parents inside when he was a kid, but ''Series/LegendsOfTomorrow'' goes further in depth and reveals that [[spoiler: while he ''did'' start the fire that killed his parents, he did it ''accidentally'' and panicked so much that he ran out of the house without waking his parents, which he still felt guilty for decades later.]]
* ''Series/{{Battlestar Galactica|2003}}'' is a semi-example. The Cylons consider humans to be their parents and claim that they have to die for Cylons to reach their potential. So Cylons tried to become a SelfMadeOrphan. It did not work well.
* ''Series/BeverlyHills90210'' character [[spoiler:Valerie Malone]] killed [[spoiler:her father]]. However, [[spoiler: her]] mother is still around.
* Every member of Prince Edmund's QuirkyMinibossSquad, the Black Seal, in the first series finale of ''Series/{{Blackadder}}'', apart from Edmund himself, but including The Hawk. Edmund does plan on exiling and imprisoning his family though were he successful in [[TheEvilPrince taking power]].
-->'''Edmund:''' He murdered his whole family!
-->'''Pete:''' Who didn't? I certainly killed mine.
-->'''Wilfred:''' And I killed mine.
-->'''Friar:''' And I killed yours.
-->'''Sean:''' Did you?
-->'''Friar:''' Yes.
-->'''Sean:''' Good on you, Father.
* ''Series/BuffyTheVampireSlayer'': Adam murders his creator, Maggie Walsh, within moments of coming on-line.
* One episode of ''Series/{{CSINY}}'' featured [[VictimOfTheWeek an elderly couple]] who were viciously attacked while they lay in bed. The chief suspect is their son, whose alibi doesn't check out. His father was killed and his mother suffered severe brain damage, who doesn't beleive he did it. She's right, it turns out that they had moved into a house owned by another elderly couple a few years before. The son of that couple went to jail after he raped his girlfriend following senior prom, and his parents testified against him in court. He retuned home to kill his own mother and father, but ended up attacking someone else.
* Several Series/CriminalMinds unsubs have done this. The most prominent examples are Frank ([[spoiler:who killed his own mother and never knew his own father]]), The Reaper aka [[spoiler:George Foyet]] and Billy Flynn ([[spoiler:who shot his own mother in what he saw as an act of mercy]]).
* In one sketch on DaveAllenAtLarge, a priest knocks on the door of a house, and a little girl answers. The priest says, "I'm collecting for the orphanage." The little girl says, "Hold on a moment," and disappears inside. Two gunshots are heard. The little girl returns and says, "I'm ready."
* Averted and parodied in the first episode of Series/{{Dexter}}, whose protagonist/narrator is a serial killer, when he explains in a narrative that both his parents are dead, immediately adding "I didn't kill them. Honest." [[spoiler:It is revealed in the second season that Dexter actually inadvertently [[DrivenToSuicide drove his father to suicide]], much to Dexter's surprise.]]
** Also, [[spoiler:Brian, Dexter's brother (also a serial killer), offed their biological father.]]
* ''Series/DayBreak'': Hitman Miguel Dominguez was originally locked up for killing his own parents. It's later revealed that he did this to protect his sister from their abusive father.
* ''Series/DoctorWho'':
** It's also pretty likely that the Doctor killed his parents at the end of the Last Great Time War, although we don't really know whether or not his parents were still alive when he wiped out the Time Lords. WordOfGod from Creator/RussellTDavies is of the opinion [[spoiler:the Doctor killed his mother when he ended the Time War. Given that dialogue in ''The End of Time'' reveals Time Lords were being killed and resurrected repeatedly during the War, this may be viewed as something of a release.]]
** The [[spoiler:Toclafane]] killed ''millions'' of their ancestors before their own birth, thanks to a "paradox machine" holding the GrandfatherParadox at bay.
* ''Series/GameOfThrones'':
** [[spoiler:Tyrion Lannister caused the death of both of his parents, although of course he didn't actively try to kill his mother; his mother died while giving birth to him, and as an adult, he murdered his father, Tywin. He is undoubtedly viewed as this by Cersei and apparently Jaime following his murder of Tywin. Tyrion admits as much.]]
--> [[spoiler: '''Tyrion:''' I killed my mother Joanna Lannister on the day I was born. I killed my father Tywin Lannister with a bolt to the heart. I am the greatest Lannister killer of our time.]]
** Later on, [[spoiler:Ramsay [[BastardBastard Snow]][=/=]Bolton kills his father and stepmother in rapid succession, along with their newborn son(whom he'd regarded as a threat), thereby taking control of House Bolton and the North]].
** Season 2 extras (and the books) all but state outright that Gregor Clegane murdered his father, and probably his (unnamed) sister as well.
* ''Series/{{Gotham}}'': Jerome Valeska is introduced after he killed his own mother, whom he absolutely despised for her promiscuous lifestyle. After being sent to Arkham Asylum, he escapes and becomes a PsychoForHire to Theo Galavan, and murders his biological father to pin the escape on him.
* Sylar on ''Series/{{Heroes}}'' killed his mother semi-accidentally, in the fight after she tried to stab him with a pair of dressmaking scissors.
** Peter Petrelli attempted to kill his pop Arthur. He failed, but his attempt was finished by Sylar, who'd been suckered into believing that Arthur was his father as well.
** Narrowly [[SubvertedTrope subverted]] in ''[[http://en.wikipedia.org/wiki/Shades_of_Gray_%28Heroes%29 Shades of Gray]]'' when Sylar tracks down his father, Samson Gray. Samson seems indifferent when he meets Sylar, and when Sylar announces his intentions to kill him, he reveals he is already dying from cancer. Samson also reveals he has a power similar to Sylar's, including an acquired ability that paralyzes a person as if they were drugged. He also shares knowledge of Sylar's methodology, picking easy, helpless targets rather than going after "big game." When Samson witnesses Sylar heal instantly after accidentally cutting himself, he tries to take the ability from Sylar by paralyzing him. Sylar, however, manages to override it. Samson points out that taking his ability will not harm him as he can heal, but Sylar says he doesn't wish for his father to have such a power, and decides to leave. Samson begs Sylar to kill him, [[CruelMercy but Sylar says his cancer]] [[FateWorseThanDeath will eventually do so anyway]], and leaves.
* Done on ''Series/LawAndOrder'' original flavor at least once; the girl in question even received a college scholarship. (The admissions board had nicknamed her "Little Orphan Annie.") She was seriously disturbed and committed another murder. A key part of getting her for the latest murder was charging her with fraud for accepting the scholarship under false pretenses.
* Parker from ''Series/{{Leverage}}'' certainly seems to be a case. In flashback, we saw her having a favored toy taken away by her foster father. Next scene shows her holding the toy while walking down the driveway. Then the house explodes.
* Benjamin Linus, the BigBad of ''Series/{{Lost}}'', may have lost his mother to perfectly innocent DeathByChildbirth, but he hated the resentment from his father so much that he killed him [[spoiler:and the rest of the Dhama initiative]] with a painful-looking nerve gas.
-->'''Ben:''' You know, I've missed her too. Maybe as much as you have. But the difference is, for as long as I can remember, I've had to put up with ''you''. And doing that required a tremendous amount of patience. Goodbye, Dad.
** Also, Kate killed her step-father, who then turned out to have been her birth father, for abusing her and her mother.
*** And depending on how you look at it, when Locke forced Sawyer to kill Locke's father.
*** Let's be fair -- Locke didn't ''force'' Sawyer to do it as much as he manipulated him into doing it. It looked like Sawyer was going to pass on killing Cooper, until Cooper, in a boast about his long career as a con man, admitted to using the name "Tom Sawyer" during a previous con. Oops...
*** Sawyer ''symbolically'' played this trope straight, since Cooper was the con man who destroyed Sawyer's family, which led Sawyer to a life in the same business.
* In the ''Series/MastersOfHorror'' episode "Imprint", the disfigured prostitute tells Christopher how she beat her father to death after he raped her when she was still a child.
* Morgana on ''Series/{{Merlin}}''-her mother and the man she looked to as a father and believed for a long time was her father were already dead, but she gave Agravaine the amulet to kill the wounded Uther-her birth father.
* ''Series/MillionYenWomen'': One of the women was abused by her father and later turns out to have gotten both her parents killed because of it.
* ''Series/MurderInTheFirst'': Erich Blunt has his own father murdered (by his maternal grandfather, no less).
* ''Series/OnceUponATime'':
** Regina [[{{Patricide}} killed her father]] in order to enact her curse. [[spoiler: Her mother survived longer, but Regina was manipulated into killing her in Season 2. By Snow.]]
** Season two shows that [[spoiler: Red killed her mother]], though that was [[AccidentalMurder an accident]].
** Rumplestiltskin killed his father ''twice'', first by stabbing him in the back to kill his mortal body, and then again during the trip to the Underworld in season 5 by using water from the Acheron river to send Pan's soul to the Worse Place. [[spoiler: He finishes the job by killing his mother, the Black Fairy, in the season 6 finale. Given both parents were villains, nobody was particularly upset.]]
** Hook killed his own father (his only identified parent) out of anger at being "replaced" by a younger son after Brennan had sold Hook and his older brother into servitude aboard a ship in order to escape being arrested.
* On ''Series/{{Smallville}}'' ComicBook/LexLuthor murders his ArchnemesisDad Lionel as his [[MoralEventHorizon final step]] into true villainy. Lionel himself was revealed to be one of these earlier in series, having had his friend Morgan Edge kill his [[TheAlcoholic Alcoholic]] AbusiveParents in a gas fire. One can only wonder what Lex's children will do, should he have any...
** Technically Tess kills Lionel as well, though it's his AlternateUniverse counterpart. Regardless, he is still considered her father even by Tess herself, and she kills him [[OffingTheOffspring in self defense]].
* ''Franchise/StarTrek'' uses this trope in Klingon mythology. According to it, the gods created Klingons, who then turned around and killed them for the trouble.
* The EnfanteTerrible villain of the ''Series/{{Supernatural}}'' episode "Provenance". Twice - her birth family and her adoptive one.
** Also in ''Series/{{Supernatural}}'', Bela is revealed to have killed both her parents [[spoiler: by making a deal with the demon Lilith for them to meet with an accident]]. The other characters are allowed to believe it was for the insurance money, while the audience is shown scenes that strongly imply her father sexually abused her. [[DramaticIrony "They were lovely people."]]
* ''Series/{{V 2009}}'': In the season 2 finale, PapaWolf Ryan was finally reunited with hybrid daughter Amy who Anna had been holding hostage this season to make him work for her. However in his absents she has become an EnfantTerrible and the little girl strangles and kills her father when he tried to save her and declared her loyalty to Anna.
* In ''Series/TheXFiles'' episode Eve two girls who appear to be identical twins who live on opposite sides of the country kill their fathers at the same time. It turns out the two girls are part of a cloning project that was originally carried out by the government but is now being continued by another one of the clones. The clone adult that created the two girls wasn't behind the murders... the little girls were just evil.
* The titular hero of ''Series/WynonnaEarp'' accidentally killed her father when she was twelve, while trying to shoot the demons abducting him. Wynonna grew up in psych wards and foster homes after that, and the guilt still weighs on her despite later reveals that her father was not the greatest man.
* ''Series/LegendOfTheSeeker'': Mord-Sith are forced to kill their fathers as the final part of the training they undergo.
* ''{{Series/Inhumans}}'': Black Bolt vaporized his parents using the voice ability which he has.

[[folder: Manhua and Manhwa]]
* In ''Manhwa/KillingStalking'', Seungbae wonders if [[spoiler: Sangwoo]] killed [[spoiler: his]] missing parents. [[spoiler: The truth isn't ''that'' simple however: Sangwoo easily admits to having murdered his abusive father, but whether or not his mother died at his hands or his father's still isn't revealed. There ''are'' panels from Sangwoo's perspective of him strangling his mother, [[UnreliableNarrator but there's nothing concrete to prove if these were memories, or if he was hallucinating]].]]

* Music/{{Aerosmith}}'s song "Janie's Got a Gun". She shoots her dad because of the abuse he inflicted on her.
* Music/DirEnGrey's song "Berry" tells the story of a nine-year-old girl who gets sick of her parents abusing her, takes her father's gun, and shoots them. If that's not disturbing enough, the girl's favorite food is jam on bread, and the blood her parents shed is referred to as raspberry jam.
* [[Music/TheDoors Jim Morrison]] fantasized about killing his father (and also knocking off Brother and Sister Morrison for good measure) in the 1967 performance piece "The End" (oh yeah, and then he raped his mother). It was later parodied by Music/MeatLoaf and Music/JimSteinman in 1993's "Wasted Youth".
* Music/TomLehrer's song "The Irish Ballad", from ''Music/SongsByTomLehrer'', details the life of one of these:
-->About a maid I'll sing a song\\
Who didn't have her family long\\
Not only did she do them wrong\\
She did every one of them in...
* Music/SoundHorizon gives us "Yield", in which the protagonist kills one or both of her parents due to her incestuous feelings towards one of them.

* OlderThanFeudalism: The [[Myth/GreekMythology Greek myth]] of Oedipus has him killing his father, without recognizing him, and after he's raised by adoptive parents who don't tell him he's adopted. He's indirectly responsible for mother's death when the revelation of their SurpriseIncest drove her to suicide.
** Greek gods love to do this as well: Uranus was overthrown by Cronus who was overthrown by Zeus.

* ''Radio/BleakExpectations'': Series BigBad Mr. Gently Benevolent is one. It was his second act of evil (the first was him punching an annoying boy who'd caused him to finally become evil). Played with, in that neither his mother or his step-father are actually upset about this. His step-father ''praises'' him for having "finally grown a backbone", and his mother says [[SoProudOfYou she's proud of him]].

[[folder:Professional Wrestling]]
* Wrestling/{{WWE}}'s Wrestling/TheUndertaker ''may'' be a self-made orphan, or may not be. All we really know is that his parents died in a fire at the funeral home they owned and operated. At various points, we've been told that he set it by accident, he set it on purpose, his half-brother Wrestling/{{Kane}} set it, etc. It's all very confusing and pointless.
** Nah, [[http://www.youtube.com/watch?v=uNCRvCc4XY0 Undertaker definitely started the fire.]]
** Then again, this ''was'' during Taker's Wrestling/MinistryOfDarkness [[FaceHeelTurn phase]], when he was allied with Wrestling/PaulBearer again, so there's definitely a hint of ambiguity/unreliability as to who did what. For we know, ''[[DevilInPlainSight Bearer]]'' could've torched the home.
*** This was during Wrestling/VinceRusso's run as booker, and he loves {{Shocking Swerve}}s, even if they produce nonsensical, incoherent, unresolved storylines.
*** Vince Russo or not the backstory of both Undertaker and Kane can be easily considered a complete mess

[[folder:Tabletop RPG]]
* In the ''TabletopGame/{{Champions}}'' adventure "The Coriolis Effect," the villainess murdered her own parents by turning them into pools of slime.
* ''TabletopGame/{{Paranoia}}'' describes Chutzpah (a major stat in 2nd edition, a skill in XP) as [[RefugeInAudacity standing before a judge to be sentenced for murdering your parents-- and pleading for clemency because you're an orphan.]]
** Which is also the typical explanation of chutzpah in Jewish lore.
* In the lore of ''TabletopGame/{{Warhammer 40 000}}'', fallen Primarch Horus attempted to murder his father, the Emperor, but "only" succeeded in mortally wounding him and [[OffingTheOffspring was killed by Him in turn]].

* In ''Theatre/{{Electra}}'' and ''Theatre/TheLibationBearers'' in ''Theatre/TheOresteia'', Orestes enacts vengeance against his mother Chytaimnestra and step-father Aigisthos for their murder of his father Agammemnon. Though Electra doesn't actually wield the blade, she is guilty too.
* The protagonist of ''Theatre/LadyInTheDark'', accused of being indecisive, recounts "The Saga of Jenny", whose life was ruined by her decisiveness. To begin with, it leads to the accidental deaths of Jenny's parents (and siblings):
-->Jenny made her mind up when she was three\\
She herself was going to trim the Christmas tree\\
Christmas Eve she lit the candles, tossed the tapers away\\
Little Jenny was an orphan on Christmas day
* In the Roman comedy ''Pseudolus'', the Pimp Ballio claims to have beaten and killed his parents 'to save their Keep'.
* In the play ''The Revengers' Comedies'', the AxCrazy ClingyJealousGirl who acts as a PoisonousFriend to the protagonist is strongly implied to have started the fire that killed her parents when she was eleven because they did something minor to displease her.
* In ''Theatre/WhosAfraidOfVirginiaWoolf'', [[spoiler:George killed both of his parents by accident]].

[[folder:Video Games]]
* ''Franchise/AceAttorney'',
** Played cruelly with [[spoiler:Miles Edgeworth ''thinking'' for fifteen years that he accidentally killed his father Gregory]] and having constant nightmares about it. Subverted, in that it was proven that he was wrong: [[spoiler: Gregory was murdered by his rival Manfred Von Karma, who later manipulated the surroundings to make everything think Edgeworth had done it.]]
** In the final case of ''VisualNovel/ApolloJusticeAceAttorney'', a young girl named Vera Misham is put on trial for killing her father, but she is innocent. [[spoiler:The actual killer is Kristoph Gavin, who also tries to kill ''her''.]]
** ''Dual Destinies'' has [[spoiler:Athena Cykes eventually accused of murdering her mother Metis (the initial "culprit", Simon Blackquill, was TakingTheHeat)]] and, unlike with Edgeworth's case, everyone believed it was a deliberate act, [[SympatheticMurderer albeit one with sympathetic motives]] (it was thought that [[spoiler: Metis was experimenting on Athena, until she was driven to a breaking point]]). [[spoiler:Athena herself eventually ''believes'' she did it because [[TraumaInducedAmnesia all she can remember of that day]] was stabbing someone and feeling the blood run down the blade and onto her fingers.]] It turns out that [[spoiler: ''someone else'' killed Metis, Athena accidentally walked on the crime scene, and what she ''actually'' recalled was stabbing the real killer in self defense.]]
* In ''VideoGame/BaldursGateII'', Valygar, whose family had been long-plagued by necromancy practice, destroyed his parents after his mother raised his father from the dead as a zombie, unwilling to accept his death, and then later joined him in undeath.
* In ''VideoGame/BatmanArkhamCity'', Batman can visit [[HorrorDoesntSettleForSimpleTuesday Calendar Man]] in his cell on specific holidays, and he will happily recall one of his past murders committed on that day. Two of these holidays are Mother's Day and Father's Day.
-->'''Calendar Man:''' M was for the murderous look she gave me.\\
O meant only she was weak and old.\\
T is for her terror as she fought me.\\
H is for her heart that I now hold.\\
E is for her eyes swiftly dimming.\\
R means rot, and soon rotting she will be.\\
Put them all together, you spell "Mother".\\
A word that means... a corpse... to me.\\
''[creepy childlike voice]'' Happy Mother's Day, Mommy.\\
'''Calendar Man:''' I wasn't real close to my dad, and after my first internment at Arkham, we never spoke at all. Seems he wrote me off as a wacko. A loser. So, after I was released, I wanted to clear the air between us. Next Father's Day, I dropped by his place and suggested we go fishing. You ever go fishing with your pop? Well, it's some fun, let me tell ya. The two of us out on the water, pulling in one whopper after another... Of course, I was doing the actual pulling. Dad was baiting the hooks. You know, with a finger, a foot, an eye, whatever I had left of him. Even today, whenever I eat a nice piece of fish, I feel closer to my dear old dad.
* Deconstructed in the canon route of ''VideoGame/BlazeUnion'', where [[ButThouMust for practical and symbolic reasons, Gulcasa must kill his]] MissingMom, and she's the one who bullies him into doing it. He does not want to, but kills her anyway because by that point he has no choice if he actually wants the power to protect his loved ones. She doesn't seem to hold it against him, but this event (among others) leaves him badly messed-up for quite some time. Additionally, Route B, starring [[spoiler:Aegina. Ordene wouldn't have died if he hadn't refused treatment. Using Aegina for this is actually very practical, gameplay-wise, as [[GameplayAndStoryIntegration Ordene will not use Crusade on her]].]]
* ''VideoGame/CliveBarkersUndying'': [[spoiler:Ambrose]] beats his father to death with a pool cue, tired of him meddling in his affairs.
* In ''Franchise/DanganRonpa'''s ''VideoGame/AbsoluteDespairGirls'' The [[spoiler:Warriors of Hope (Masaru, Kotoko, Jatarou, Nagisa and Monaca)]] admit to [[KickTheSonOfABitch having murdered]] their AbusiveParents prior to the events of the game.
* ''[[Franchise/DevilMayCry Devil May Cry 3: Dante's Awakening]]'' has [[spoiler:Lady killing her father to avenge her mother's murder.]] Which doesn't count [[OffingTheOffspring the]] ''[[OffingTheOffspring other]]'' [[OffingTheOffspring thing he tried to do]]...
* [[spoiler:Adell]] in ''VideoGame/Disgaea2CursedMemories'' is forced to MercyKill his BrainwashedAndCrazy blood-parents (by their own request) near the last few levels of the game, without even knowing who they are. What's worse is that it's heavily implied that his adoptive mother was planning to tell him who his birth parents were after the end of the game. Now ''that's'' going to be an uncomfortable conversation...
* In ''VideoGame/FatalFury'', [[spoiler:Wolfgang Krauser]] killed his father [[spoiler:in a DuelToTheDeath [[KlingonPromotion to become the Earl of Strolheim]].]] He honors his old man once a year by playing [[spoiler:the older Krauser]]'s favorite music in his organ.
* Averted in ''VideoGame/FinalFantasyIV'' with Edge, who saw the results of Dr. Lugae's horrific experiments on his parents, the King and Queen of Eblan. Edge is forced to fight his parents, who have become monsters, but he is saved from having to kill them by their coming to their senses, saying farewell to him, and killing themselves.
* In ''VideoGame/FinalFantasyX'', Seymour kills his own father before the game starts. The reason why is because his father had him and his mother exiled after several Guado, in a case of FantasticRacism, decried the UnholyMatrimony. Guado's father's statements in the sphere indicated that he accepted his fate fully as atonation for this sin.
* This can be done in many, ''many'' cases in ''Franchise/FireEmblem'':
** In ''VideoGame/FireEmblemGaiden'' and its remake ''Echoes: Shadows Of Valentia'', [[spoiler:Emperor Rudolf's ZeroApprovalGambit to protect both Rigel and Zofia includes him being slain by LaResistance... which is led by his son Alpine Alm Rudolf aka Alm, one of the protagonists. Alm, [[RagsToRoyalty who had been raised away in a village]], has no idea that his biggest enemy is his biological father: he only finds out during the climatic battle against Rudolf, and naturally ''[[HeroicBSOD he doesn't take it well]]''.]]
** In ''VideoGame/FireEmblemJugdral'' second part, there's [[spoiler:the [[DemonicPossession Lopto!possessed! Prince Julius]] attacking his mother Deirdre ''and'' his younger sister Julia. WhiteMagicianGirl Deirdre manages to use her Warp staff to save Julia, but isn't lucky enough herself, and she dies at Julius's hands.]] Similarly, in the first half King Chagall of Augustria and Duke Andorey of Jungby killed their fathers to ascend to their respective thrones. (The second earns the scorn of [[EvenEvilHasStandards his fellow conspirator Duke Langobalt]] for that). Also, for major VideoGameCrueltyPotential, in both halves the player can have some of their own units kill their {{Archnemesis Dad}}s: Tailto (daughter of Duke Reptor) and Lex (son of the aforementioned Duke Langobalt) for the first part, either Johan or Johalvier (sons of King Danan) in the second.
** In ''[[VideoGame/FireEmblemElibe Fire Emblem: The Binding Blade]]'', [[spoiler:after numerous attempts on his own life from [[OffingTheOffspring his father, King Desmond]], Prince Zephiel of Bern [[TheDogBitesBack decides to turn the tables]]. He fakes his own death, then at his funeral, when Desmond opens the coffin to check on his son, Zephiel stabs him dead on the spot.]]
** In ''VideoGame/FireEmblemTheSacredStones'', by putting Ross in the range of a Berserk staff... you can potentially have him kill Garcia, his father, [[GoodParents whom he actually loves to death otherwise]]. ([[OffingTheOffspring And you can do the reverse as well]]) [[VideoGameCrueltyPotential Whoopsie.]]
** The BigBad of ''[[VideoGame/FireEmblemTellius Path of Radiance]]'', King Ashnard, is revealed to have killed not only his parents but his ''entire family''. He was pretty far back in the line of succession, so if he wanted to become king, some pruning of the family tree was required. [[note]](In ''Radiant Dawn'' [[spoiler:an ending sequence only available on a NewGamePlus implies that Soren, a mandatory recruit who was instrumental to Ashnard's defeat and death, was Ashnard's son.]])[[/note]]
** It's possible to do this in ''VideoGame/FireEmblemAwakening'' in ''The Future Past'' Paralogue as long as [[spoiler: the Avatar is the mother of Lucina]] or [[spoiler:the father to another Second Generation character.]] Although ''technically'' the offed person was possessed by the BigBad and viewed this as a MercyKill. And to be fair, the BigBad killed the other parent in the [[spoiler:first]] case ([[spoiler:while possessed]].
** One can do this in ''VideoGame/FireEmblemFates'', in the following cases: [[spoiler:The Avatar (killing his/her biological father Anankos, or either his/her mother Mikoto, his/her ParentalSubstitute Sumeragi (both were forcibly revived by Anankos) [in the ''Revelation'' path] or his/her abusive father Garon (better said, his doppelgänger who posed for years as the real Garon)]]; [[spoiler:Azura (killing her also forcibly revived mother Arete)]], [[spoiler:any Hoshidan sibling (ParentalSubstitute Mikoto or birth father Sumeragi)]], [[spoiler:any Nohrian sibling (the aforementioned fake Garon)]] and especially [[spoiler:Female Kana (but only if she's mothered by Scarlet, who dies and then is revived as a zombie in ''Revelation'')]] [[VideoGameCrueltyPotential OUCH!]]
*** When [[spoiler:Beruka]]'s backstory is unveiled, she says that [[spoiler:she killed her master and teacher, the closest to a ParentalSubstitute she had.]]
*** The ''Heirs of Fate'' DLC, taking place in an AlternateUniverse, also involves this: [[spoiler:the fathers (and mother, in the case of Male Kana) are all killed to protect their children from Anankos' takeover of their worlds, and when the kids reunite and fight back, they find out that their ultimate enemies are ''their fathers and Male Kana's mother'', forcibly revived by Anankos. In a subversion, when this is said and done, the kids manage to make their way back to their homes - which have been restored, ''plus'' the parents they had to slay are alive.]]
* In the final [[HarderThanHard Custom Night (Golden Freddy V. Mode)]] cutscene of ''VideoGame/FiveNightsAtFreddysSisterLocation'' [[spoiler: Michael Afton's lines give off a really strong implication of this being his goal. Whether he's doing it to get back at his dad for getting him killed or kill him in his victims' stead is left ambiguous.]]
** [[spoiler: Either way, he burns him, along with every other remaining animatronic, down in the [[VideoGame/FreddyFazbearsPizzeriaSimulator next game]]]].
* In ''VideoGame/GodOfWar'', Kratos' mother's note in Hades confirms her death, and the ending of the game has him slaying his father, Zeus. Though Kratos didn't actually mean to kill his mother: she was turned into a monster and he had no choice, and it's shown later that [[EvenBadMenLoveTheirMamas he was really sad about killing her]].
* ''VisualNovel/HigurashiWhenTheyCry'':
** [[spoiler:Satoko]] is a tragic example. In her backstory, she had become insane and extremely paranoid as a result of [[spoiler:suffering from [[HatePlague Hinamizawa Syndrome]]]], to the point where she perceived her own parents as a threat to her and pushed them both off a cliff to their deaths. It was essentially a twisted kind of self-defense.
** [[spoiler:Natsumi]] is this in her arcs. [[spoiler:She was infected with the same HatePlague, which caused her to kill both her parents and her grandmother.]]
** [[spoiler:Hanyuu]] made her daughter Oka ritually sacrifice her in order to [[spoiler:make her the DeityOfHumanOrigin that she's been ever since]].
* Agent 47 of ''VideoGame/{{Hitman}}'' snaps the neck of his maker at the end of the first game.
* Quite tragic case in ''VideoGame/TheKingOfFighters'': [[spoiler:EmotionlessGirl Leona did ''not'' want to kill her father and the people in her village, but did so under MoreThanMindControl from MagnificentBastard Goenitz. He brainwashed this then-under-12-years-old girl into doing so to get back at her father, ex Orochi Head Gaidel, for [[DefectorFromDecadence refusing to re-join]] his QuirkyMinibossSquad. Poor Leona went into an HeroicBSOD and wandered in the jungle for several days, afflicted with TraumaInducedAmnesia, until she was adopted by ColonelBadass Heidern (who had lost his daughter and wife a while ago, at the hands of Rugal). Leona then grows up into a powerful ActionGirl, but remains amnesiac... until the events of KOF 97; she's almost DrivenToSuicide when she remembers, but then Gaidel goes SpiritAdvisor on her and tells her to keep living.]]
* In ''VideoGame/Left4Dead'', Zoey had to kill her own father to prevent him from turning into a zombie after he had been bitten by his zombiefied ex-wife. Turns out later that Zoey is immune, something that is inherited to females from the father, meaning that her father was also immune to the infection and would have survived anyway. When she realizes this, she breaks into tears for having killed him when he would avoid zombiefication completely.
* Maya from ''[[VideoGame/LegendOfLegaia Legaia 2: Duel Saga]]'', accidentally killed both her parents at a young age when she lost control of her magical powers. The event left her mute, but she gets over it later.
* Wrex from ''Franchise/MassEffect'' is from the Krogan, an [[PlanetOfHats entire race]] of {{Blood Knight}}s. However, after the Krogan rebellion, the Council more or less sterilized his entire race; their birthrate became so low, they are slowly going extinct[[note]] The details of this get fudged a bit in ''VideoGame/MassEffect2''. The fertility rate is set to 1 in 1,000 to compensate for the Krogan being catapulted into the stars (they were needed for the [[BugWar war against the Rachni]]). It's not an attempt at extinction so much as an attempt to prevent a Baby Boom of epic proportions, resulting in the Krogan trying to wage war on the universe. But they're Blood Knights, after all, so they still tend to get themselves killed at alarming rates....[[/note]] Wrex's father, the leader of their clan, had wanted to go to war again, while Wrex had the foresight to try and figure out a way to save their race. Wrex had to kill him in self-defense, then decided to abandon his people.
** Liara provides a rare heroic example if you bring her with you on Noveria - she helps you kill her own mother, Matriarch Benezia, who was an outright ''villain''. [[spoiler:[[BrainwashedAndCrazy Well]], [[TragicMonster not]] [[AntiVillain quite]]]].
** And also in ''VideoGame/MassEffect2'' one can convince Jacob Taylor to abandon his father on a planet with the crew that he had driven mad through forcing them to eat toxic food that caused neural decay. One can even LeaveBehindAPistol for him with only half a thermal clip.
** Another heroic example in ''VideoGame/MassEffect3'', if she's still alive, Miranda will kill her father who's holding her sister hostage, the second he's convinced to let her go. [[KickTheSonOfABitch Hard to say he didn't deserve it.]]
* According to {{Fanon}}, [[EnsembleDarkhorse Zero]] from ''Videogame/MegaManX''.
* Solid Snake famously offed his dad -- or at least [[TrulySingleParent the donor of the genes]] which created Snake -- in the ''Franchise/MetalGear'' series.
* Psycho Mantis of ''VideoGame/MetalGearSolid'' woke up one morning to find his entire village in flames, all its inhabitants, including his father, dead, victims of his psychic powers (his mother was a victim of DeathByChildbirth). Well, that's how ''he'' tells it. He probably just did it for shits and giggles.
** As his powers began to develop as a child, he started to hear his father's thoughts. He came to the realization that his father really and truly hated him because he was responsible for his wife's death, though he acted like he loved him. One day, Psycho Mantis burned his entire village to the ground out of pure hatred for humanity, and especially his father.
** The trope is also used symbolically, and for the protagonists even, with Snake killing his "father" Big Boss, Raiden killing his "father" Solidus, and [[spoiler:Big Boss killing his "mother" The Boss]].
*** That first one, while not lacking for symbolism, isn't symbolic in the way implied with the quotation marks, what with Big Boss actually unambiguously being Snake's biological father. [[CloningBlues Well, a little ambiguously]].
* In ''VideoGame/SilentHill2'', [[spoiler: Angela Orosco did it to her father, killing him (and possibly her brother too) with the same kitchen knife she gives to James. Not that [[AbusiveParents he didn't]] [[ParentalIncest deserve it]].]]
* In ''VideoGame/PillarsOfEternity'', a [[PlayerCharacter Watcher]] with the Drifter background can self-describe as this, word-for-word, when explaining their past to Calisca in the prologue. The Watcher says their parents got what they deserved; whether or not this is true is left for the player to decide.
* In ''VideoGame/PrinceOfPersiaTheSandsOfTime'', [[spoiler:the Prince has to kill his own father in a boss fight after the latter is transformed by the Sands.]]
* [[VideoGame/SamuraiShodown Kibagami Genjuro]] claims to have killed his parents. His murder of his mother is AllThereInTheManual, at least.
* In ''VideoGame/StarStealingPrince'', [[spoiler: Snowe's]] parents are dead. [[spoiler: Edgar and Lina weren't dead from the start like you're led to believe, they faked their own deaths and appear later in the Sepulcher, where they try to destroy Snowe and his friends and Snowe and his friends have to kill them in self defense.]]
* After [[spoiler: being brainwashed throughly and made into [[BodyguardBabes one of the Dolls]] ]], [[VideoGame/StreetFighterAlpha Juni's]] first mission was going back home and killing her parents. [[http://streetfighter.wikia.com/wiki/File:Juni.jpg Here]] she goes home, allows her mother to hug her, then pulls a gun [[GoryDiscretionShot as the view pans away...]]
* ''VideoGame/StreetFighterXTekken'' confirms M.Bison [[AscendedMeme did this to his own father]] in a win quote against Chun Li.
-->'''M. Bison:''' All you women ever do is whine! I killed my father too, and you don't see me crying about it!
* [[BigBad The Wolf]] from ''VideoGame/{{Stronghold}}'' is implied to be this.
-->'''Narrator:''' The Wolf's past is shrouded in mystery, and what is known of his history is mainly patched together from stories and unreliable rumours alone. This aside, it is believed that both his parents died from natural causes in close succession shortly after his eighteenth birthday.
* '''VideoGame/SuikodenI''' has an odd example. [[spoiler:Both Tir and his father, Teo, are honorable people, but they get caught on opposite sides of a civil war. The last thing Teo tells his son after Tir has dealt the fatal blow is that he is proud of him.]]
* Balxephon in ''VideoGame/TacticsOgre'' killed his father, and later on his mother died as well. He had his brother blamed for it.
* The BigBad of ''VideoGame/TalesOfTheAbyss'' is revealed to be this in the midgame. Interestingly enough, despite being the villain of the piece it's actually a) sympathetic and b) unintentional. [[spoiler: He was strapped to a machine when he was 11 years old and forced to do a partial [[SphereOfDestruction hyperresonance]] to destroy his entire homeland. This is the very moment that set him down the path to becoming the BigBad, tied with finding out the fact certain people - including the man who adopted him and his baby sister - knew and allowed that destruction and the horrifying experiments that happened before that to happen all for the sake of [[BecauseDestinySaysSo the Score]] and the foretold "prosperity".]]
* The backstory for the Demoman in ''VideoGame/TeamFortress2'' claims that his fascination with explosives began at age six with an attempt to kill the Loch Ness monster. That first attempt cost him both his original adopted parents. The WAR comic contradicts this by having his mother alive and living with him, leading to a {{Retcon}} stating that he blew up his ''adoptive'' parents, which led to him reuniting with his birth parents.
** There's also Gray Mann, who ate the eagle who raised him from infancy.
* Baek Doo San in VideoGame/{{Tekken}} killed his father in a training accident. The fact that [[MissingMom his mother had abandoned them after his father fell into alcoholism]] didn't exactly do wonders for Baek's mental stability after the fact. Meanwhile, the Mishima tend to ''try'' to achieve this. '''''Constantly.''''' except Jinpachi Mishima who was sealed under the Hon-Maru compound by Heihachi who want to seize the Mishima Zaibatsu. [[spoiler: Kazuya finally [[KilledOffForReal succeeds against Heihachi]] at the end of Tekken 7's story mode]].
* ''VisualNovel/UminekoWhenTheyCry'':
** Dlanor A. Knox killed her own father after he violated the Knox Decalogue. Afterward, she [[NeverGrewUp stopped aging.]]
** Also, in one arc [[spoiler: George Ushiromiya]] kills his mother [[spoiler:Eva]]. It was mostly in self-defense when her SuperpoweredEvilSide [[spoiler:Eva-Beatrice]] came out in the middle of a heated discussion in regards to her ParentalMarriageVeto, though.
* Arthas Menethil, of ''VideoGame/{{Warcraft}}'' fame. After [[FaceHeelTurn losing his soul]] to the runeblade Frostmourne, he returned to Lordaeron and [[spoiler:slaughtered everyone, up to and including dear old dad]]. In fact, the cinematic trailer for the ''[[VideoGame/WorldOfWarcraft Wrath of the Lich King]]'' expansion lays on the [[DramaticIrony irony]] by juxtaposing his dad's words of wisdom with the the now-Lich King commanding his vast undead armies.
-->'''King Terenas:''' W-what are you doing?!
-->'''Prince Arthas:''' ''Succeeding'' you, father. (''stab'')
** [[spoiler:Fortunately, karma came back with a vengeance, as Terenas' soul resurrected the [[AnAdventurerIsYou heroes]] who killed him after Frostmourne was broken.]]
* In ''VideoGame/WolfensteinIITheNewColossus'', [[spoiler:B.J. Blazkowicz]] confronts and kills his father midway through the game. Though said father was an [[AbusiveParents abusive]], [[ShootTheDog dog-killing]], Nazi-sympathizing asshole who shamelessly sold out ''his own Jewish wife'' to the aforementioned Nazis, so he had it coming.
* The Id of Fei Fong Wong in ''VideoGame/{{Xenogears}}''.
* In ''VideoGame/ChzoMythos'', it was said that [[ElderichAbomination Chzo]] has done this to his entire kind.
** On a lesser event, [[BigBad John DeFoe]] kills his father and repays his brother, Matthew, [[UngratefulBastard by killing him as well]].

[[folder:Web Comics]]
* ''Webcomic/{{Archipelago}}'': Captain Snow. Started off with birds and squirrels. Later, killed his parents and apparently the rest of his family, sparing his nephew but forcing him to work for his crew. Went on to become the most feared and hated pirate captain in the world until he died of a brain tumor. [[BackFromTheDead And now he's back.]]
* The implied BackStory of [[NamesToRunAwayFromReallyFast Stabby]] in ''WebComic/BasicInstructions''.
* In ''WebComic/GirlGenius'', Anevka Sturmvoraus fatally electrocutes her father; she never shows the slightest regret, but then, it's his fault that she's a BrainInAJar controlling a robot body. [[spoiler: Or rather, a robot that only thinks she's the real Anevka, but she doesn't know that.]] The second novelization strongly implies that she killed her mother as well, though it doesn't give any context.
* ''Webcomic/{{Homestuck}}'': [[http://www.mspaintadventures.com/?s=6&p=004172 "Au revoir, Spidermom"]] in this case crossed with MercyKill since she was clearly in agony.
* ''Webcomic/{{Jack|DavidHopkins}}'': Drip was told by his horrific grandmother that he had killed his parents, in some roundabout way about his birth forcing them to live in a bad neighborhood where they got brutally murdered. But then in an arc showing how he became the AnthropomorphicPersonification of {{Lust}} it's shown that thanks to the odd nature of time in the afterlife [[spoiler: he actually did kill his parents, Lucifer led him to believe that they were an ex-girlfriend of his and her husband, and he didn't realize his mistake until he dropped their baby on his mother's torn open ribcage and got a good look at him.]] And Drip's daughter Lita is more than a bit obsessed with killing him for what [[ChildByRape he did to her mother]] and to [[ParentalIncest herself]], even committing suicide in order to follow him into hell and kill him again, though she really had no idea what she was getting into.
* Webcomic/{{Jared}} murdered his own father, the fate of his mother is as of yet unrevealed, though it's likely she met the same fate.
* Richard of ''Webcomic/LookingForGroup'' admits having killed his own father. In fact he's proud of it. Actually, he thinks of it as a funny story. But then again, anything involving killing is funny to Richard.
* Used as a threat in the comic that succeeded ''Lowroad75'', ''[[http://lowroad75.comicgenesis.com/d/20080118.html The Smashing Adventures Of The Bottomleys]]'':
-->'''Dad:''' Um... Well, you see... erm... I'm building this new machine in the basement and the TV had some really useful part...
-->'''Alice:''' Dad, If you finish that sentence I will be forced to make myself an orphan...
* Early in the prequel "Start of Darkness" (to ''Webcomic/TheOrderOfTheStick''), Xykon decides to leave home and turns his parents into zombies on the way out. He had previously done the same to his grandmother.
** We don't know if Xykon killed his grandma or she just died of natural causes and he zombified her then, but he definitely did kill his parents by siccing zombies on them and then zombified them.
* Keith Keiser of ''Webcomic/TwoKinds'' killed his drunken father in self-defence after said father had killed his own wife. On top of it, he was [[WronglyAccused accused of both murders]] and banished.
** [[spoiler:Turns out the intelligent general murdered her when he found out she was form the other Bastin nation, the one without the compulsion to follow any order.]]
* The Uricarn from ''Webcomic/TheWotch'' is a self made LastOfHisKind. It's likely he killed his parents, because in an aside, he regrets killing them all while he was still a kid. He wishes he left a female alive.
* Black Mage from ''Webcomic/EightBitTheater'' may be this; we know he's killed his (blind) brother and has said he "wouldn't use the present tense for any member of my family" (with a blood splatter in the background, no less).
** "It would have been cruel to let him live after what I did to his eyes."
* ''Webcomic/WhiteDarkLife'': Eloria murders her father to [[KlingonPromotion take his position as a Demon Lord]]. [[spoiler:It also didn't help that he purposefully tried to piss her off in the first place.]]
* ''Webcomic/WelcomeToHell'' starts out with the main character, Sock, digging three graves, having just "killed his parents... [[AccidentalMurder in his sleep]]," [[spoiler:He then proceeds to [[MurderSuicide fill the third.]]]]

[[folder:Web Original]]
* In ''Interviewing Trey'' (the sequel to ''Literature/InterviewingLeather''), the supervillain Jack O'Knaves mentions how his parents were killed right in front of him.
-->'''Jack:''' By me, but that doesn't make it hurt less.
* Grallman and Talbot from ''Literature/ToWelcomeOblivion'' killed both of their parents in their youth. Unlike Grallman, who had AbusiveParents [[TheDogBitesBack and snapped after so much abuse]], Talbot murdered his parents just because he could.
* Dr. Sloth from ''{{Website/Neopets}}'' did this.
* In ''Roleplay/SurvivalOfTheFittest'' version one, Cillian Crowe and Daphne Rudko both murdered their own parents, though Cillian was confined to an insane asylum due to his actions while Daphne got off scot free.
* From Wiki/{{Killerbunnies}}, Visceraline is rumored to be reason as to why she is absent parents, which wouldn't be unlikely, considering how she is, which leads to a bit of FridgeHorror. We also have this with a mentally ill Razelle, apparently, when she set her house ablaze while in a fit of delirium, killing her parents (along with her grandmother).

[[folder:Western Animation]]
* Fire Lord Ozai from ''WesternAnimation/AvatarTheLastAirbender'', although he used an assassin ([[spoiler:his own ''wife'', Princess Ursa, who he convinced to use a colorless, odorless poison on Azulon since he was going to make Ozai kill their own son Zuko]]).
* In ''WesternAnimation/BatmanTheAnimatedSeries'' Jason Blood claims that Klarion [[LiteralMetaphor turned his parents into mice]]. Then the camera zooms in on Klarion's cat...
* [[PsychoForHire Dark Danny]] from ''WesternAnimation/DannyPhantom'' didn't just kill his parents, he ''[[AxCrazy killed his sister, his friends, and his teacher (as well as his human self way earlier)]]''...just to [[MagnificentBastard secure his own future]].
* In ''WesternAnimation/DragonsRidersOfBerk'', it is strongly implied that Dagur the Deranged, Mad Chief of the Berserker Tribe, killed his own father. Dagur claims that his father Oswald the Agreeable "retired", later saying that he "had to be eliminated" so that he could become chief. Oswald is never seen or heard from ''once'' in the show.
* The Omnicronians of ''WesternAnimation/{{Futurama}}'' eat their mothers when they grow up. Leela understandably regrets telling a baby Omnicronian that she hoped he would always think of her as a foster mom after he tells her this.
** Leela nearly does this herself when she and her mutant parents are reunited. She takes the photos they have of her as proof that they are creepy stalkers who murdered her birth parents. Her parents go along with it because they'd rather die than let their daughter live with the shame of being a mutant. Fortunately, Fry and the others arrive just in time to reveal the truth.
* ''WesternAnimation/IronManArmoredAdventures'':
** Justin Hammer’s father died under mysterious circumstances and Justin comments about a deity that did whatever necessary to gain power. Nick Fury even suspects that Justin killed his father to take control of Hammer International.
** In one episode a JerkAss classmate implies that Tony did this to his father because of their (actually friendly and good-spirited) competition to one-up each other's inventions. It's completely false and Tony [[BerserkButton does not take it well at all]].
* A variation on ''WesternAnimation/JimmyTwoShoes'': Every member of [[RoyallyScrewedUp the Heinous Family]] has [[HumanPopsicle frozen their father]] and [[KlingonPromotion taken over Miseryville]]. Since the family is different generations of {{Satan}} (a fact clearer in the original pitch) you get the impression that this is as close to death as they can get.
* In ''WesternAnimation/TheSimpsons'', Mr. Burns fills out a health form:
-->'''Mr. Burns:''' Cause of parents' death?..."Got in my way."
** Another episode has a brutal prison warden [[FreudianExcuse attempting to justify himself]]:
--->'''Warden:''' [sombre] When I was a young boy, I saw my father murdered in front of my eyes. [suddenly cheerful] By me.
* In ''WesternAnimation/SpiderManTheAnimatedSeries'', the Kingpin is as strongly implied to be this as the censors would allow. After being left for the police by his father in a robbery gone south, he [[HadToComeToPrisonToBeACrook walked out of prison]] with the physical strength, connections and mentality needed to build his empire. It's not made clear what he did to his father, but Smythe is shocked that even Kingpin could be so ruthless. Near the end of that storyline, the Kingpin makes his own son Richard take the fall for Kingpin's exposed scheme. Along his wife left him for earlier actions, the Kingpin is left alone holding a photo of his shattered family, bitterly wondering when his own son would take his revenge.
* M Bison, BigBad of ''WesternAnimation/StreetFighter'', doesn't understand why Chun-Li is [[YouKilledMyFather angry at him,]] retorting with this trope.
-->'''Bison:''' Yes, yes, I killed your father! What is it with you women anyway?! I killed my father too and you don't hear me whining about it!
* ''WesternAnimation/TeenTitans'': Raven ''destroys'' Trigon at the end of the fourth season, and he's never seen again since then.
* ''WesternAnimation/GravityFalls'' has [[EldritchAbomination Bill]] [[PsychopathicManChild Cipher]] who, when asked if he has a family in his Reddit AMA, replied "NOT ANYMORE", this was hinted at in "Weirdmageddon: Take Back The Falls" when Bill Cipher said he "liberated his dimension." The tie-in book ''Literature/GravityFallsJournal3'' explicitly says that he killed his parents, along with [[WhereIWasBornAndRazed everyone else]] in his home universe.
* In ''WesternAnimation/SouthPark,'' [[spoiler:Cartman]] manipulated the events that resulted in the death of his father, though he actually didn't realize they were related until several seasons later, when it was [[LukeYouAreMyFather revealed]] by his [[CainAndAbel vengeful half-brother]], [[spoiler:Scott Tenorman]].

[[folder:Real Life]]
* Atif Rafay, who (with the help of his friend Glen Burns) allegedly murdered not only both his parents but also his severely autistic older sister in Bellevue, Washington in 1994. The case is notable in that while the crime was committed on American soil, all the people involved - victims and suspects - were Canadian citizens; the Rafay family had moved to Bellevue from Vancouver, BC not long before the murders and both Rafay and Burns went back there after being released and before coming under official suspicion by Bellevue's police. This resulted in cross-border cooperation between Bellevue police and the RCMP to get confessions and arrests, snags involving the possibility of the death penalty [[note]]Canada does not have the death penalty and will not extradite its citizens to face foreign courts if such a verdict is considered[[/note]] and myriad other legal wranglings before ''finally'' going on trial in 2004.
* Brian Blackwell bludgeoned his parents after he used their expenses to fabricate being a semi-pro tennis player, [[DisproportionateRetribution and they called him to explain]]. During the murder he was 18 years old, and left their bodies to decompose for a year in what was once their house until the police found them. He is now serving a life sentence, although his case was notable for being the first example of using [[http://en.wikipedia.org/wiki/Narcissistic_personality_disorder Narcissistic personality disorder]] as a defense before a court.
* Caril Ann Fugate, the teenage girlfriend of 50's spree killer Charles Starkweather, was allegedly involved in the murders of her mother, stepfather, and sister. Like UsefulNotes/LizzieBorden however, it will probably never be known for sure the true extent of her guilt (or innocence) in the case.
* [[http://www.truecrimereport.com/2010/02/john_caudle_14_killed_his_pare.php 14-years-old John Caudle kills his mom and stepdad to get out of doing his household chores.]] According to the [[http://www.denverpost.com/news/ci_18227156 Denver Post Website]] he was sentenced for 22 years after a plea deal. He'll be out June 8, 2033.
* Kip Kinkel, a school shooter later diagnosed with paranoid schizophrenia, first killed his parents after years of not living up to their expectations in his eyes, killing them after they were told he had earlier brought a gun to school and was facing expulsion. He was restrained after killing an additional two people at his school and sentenced to life in prison after pleading guilty.
* The Mexican film maker León Salvador Fermet was believed to had been stabbed to death by thieves, which was said to have driven his wife María Adriana to hang herself. [[http://www.theclinic.cl/2016/10/01/macabro-vuelco-en-asesinato-de-cineasta-mexicano-su-hijo-lo-mando-a-matar/ However, their son (whose name hasn't been revealed) has been accused of hiring hitmen to kill the two of them.]]
* UsefulNotes/LizzieBorden (allegedly) in 1892. She was acquitted, and there are a variety of books offering various theories of the case, with a range of possible suspects, including Lizzie's older sister Emma (who if guilty, would qualify as well). As Andrew Borden had been a pretty despicable and hated character who had swindled a lot of people in his business career, the range of suspects should have been pretty large after all.
** "''Lizzie Borden took an axe and gave her mother forty whacks, and when she saw what she had done she gave her father forty-one.''"
* In Savannah, Georgia, a girl named Lottie was raised by her aunt Louisa and her uncle Aaron and got along well with Anna, her stepmom's sister. [[YourCheatingHeart She once caught Anna hugging and apparently kissing her uncle/dad]]; after an HeroicBSOD, she killed Anna by lacing her tea with poison to "protect" her family. It turned out that Anna was her long-lost mother, [[TeenPregnancy who had her as a teen]] [[GiveHimANormalLife and left her in the care of her sister and brother-in-law]], [[SecretKeeper asking them to not tell the truth]]. [[IronicHell Whoops.]] (Lotti was acquitted, but [[GoMadFromTheRevelation soon she totally lost it]] and was committed to an asylum for the rest of her life. Her ghost supposedly haunts the house she lived in, [[http://www.realhaunts.com/united-states/forsyth-park-inn/ now a hostel named Forsyth Park]], once featured in ''Haunted Houses''.)
* [[http://en.wikipedia.org/wiki/Lyle_and_Erik_Menendez The Menendez brothers]] killed both their parents with shotguns and gained their considerable wealth in August 1989, initially telling the police it could be related to organized crime. The investigation didn't focus on them for several months, only getting a break when the former girlfriend of the psychologist of one of the brothers informed police about his confession during therapy. A dispute over police access to the session tapes went all the way to the California Supreme Court (which ruled that some of the tapes could be used due to alleged threats to the psychologist, but not the confession tape), before the murder case itself finally went to trial in 1992. The brothers claimed hideous abuse as a FreudianExcuse, but were sentenced to life in prison without the possibility of parole after the judge limited much of their abuse testimony during their second trial.
* One of the oldest and most infamous examples was that of the Roman Emperor UsefulNotes/{{Nero}}, who ordered the assassination of his mother, [[EvilMatriarch Agrippina the Younger]], over a power dispute (the exact trigger is disputed, but it's clear he thought her too meddlesome). (Both his biological father, Gnaeus Domitius Ahenobarbus, and his adoptive father, the emperor Claudius, had died some years previously.) Most accounts claim he originally ordered that she be [[MakeItLookLikeAnAccident drowned in a ship rigged to sink]], but when she escaped from that, he just had a guard just stab her. According to legend, when she saw the guard with his sword drawn, she said, ''Ventrem feri''--"[[FamousLastWords Strike at my womb]]."
* In Amityville, Long Island, New York, Ronnie [=DeFeo=] shot and killed his parents and four siblings in bed on November 13, 1974 at 3:15 am. The hauntings the book and movies based off of the book claimed aren't real, though, just the crime.
* In Bellevue, Idaho, [[https://en.wikipedia.org/wiki/Sarah_Marie_Johnson Sarah Marie Johnson]], then 16, killed her parents on September 2, 2003 because they forbade her from dating a 19-year-old boy.
* [[http://en.wikipedia.org/wiki/Suzane_von_Richthofen Suzane von Richthofen]] ([[http://news.bbc.co.uk/2/hi/americas/5207124.stm descendant of the]] RedBaron) is a Brazilian girl that is in prison for killing both her parents when she was 19 years old, with help from her boyfriend and his brother. It made quite a sensation in the media.
* One case in Medicine Hat, Canada. A young girl, influenced by her much older boyfriend, murdered her entire family.
* In Finland, a teenaged girl coaxed some older boys to kill her mother over domestic differences; fortunately, the crossbow bolt intended to do the job only grazed her skull, and she managed to escape.
* In 1954, an incident happened in Christchurch, New Zealand where Pauline Parker and her friend Juliet Hulme killed her mother. Their story was made into the film ''Film/HeavenlyCreatures'' by Creator/PeterJackson; Creator/KateWinslet starred as one of the girls.
* One that changed (a small part of) history: one fine summer evening in Nepal, Crown Prince Dipendra walked into a family dinner and shot the whole place up, killing his father, King Birendra, his mother, Queen Aishwarya, two of his siblings, and five other relatives, before killing himself (although he would then take a few days to die). As a result, his uncle Gyanendra took the throne. Through a long series of events, this massacre led to the abolition of the Nepalese monarchy in 2008.
** That's the official version, anyway. Many in Nepal accused Gyanendra of being an EvilUncle who arranged the massacre (in collaboration with Chinese spies) and framing Dipendra, [[KlingonPromotion so that he could have the throne for himself.]] Fueling this theory is the claim that the right-handed Dipendra "shot himself" in the left side of his head, which is a relatively unlikely suicide.
* In 2011, a seventeen-year-old boy by the name of [[http://www.rollingstone.com/culture/news/tyler-hadleys-killer-party-20131218 Tyler Hadley]] murdered his parents with a hammer. Then he threw a massive WildTeenParty.
* In 2015, a woman named Clauddine "Dee Dee" Blancharde was murdered and her IllGirl daughter Gypsy Rose disappeared. [[https://www.buzzfeed.com/michelledean/dee-dee-wanted-her-daughter-to-be-sick-gypsy-wanted-her-mom?utm_term=.qnYDYWyG3#.fbEwGyz6K It turns out]] that Dee Dee had [[MunchausenSyndrome Munchausen Syndrome by Proxy]] and, through several years, [[AbusiveParents she]] forced Gypsy to pretend being an IllGirl (attracting both attention and benefits), until Gypsy got rid of her with the help of her online boyfriend Nicholas Godejohn.
* In the early 1970s, Michael Morgan of Georgia, under pressure of his wife Hollis Wingo Morgan, who threatened him to no longer let him see his children again, hired his brother and friends to murder his parents [[http://www.lawskills.com/case/ga/id/124/67/index.html and got a death sentence]].
