* ''Film/Midsommar'' [[DownerBeginning opens]] Dani’s sister Terri killing both of their parents in a MurderSuicide.

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.

* ''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]].

* 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.

* In ''Film/FreddysDeadTheFinalNightmare'', Maggie kills Freddy Krueger, her father. [[JustifiedTrope However, he was already a horrifically evil serial killer]].

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 their parents or something [[FateWorseThanDeath genuinely horrific]] happened to their parents so that they were forced to kill them. It can also be justifiable if said parent was going to be OffingTheOffspring anyway, and the offspring in question needed to defend themself and had no choice. Or, it may just be because the child HatesTheirParent. As a result, it goes without saying that this is a MoralEventHorizon for ''many'' people, especially if the parents were innocent and loved their child who killed them and less so if they [[AssholeVictim totally deserved their death]].

* ''WebVideo/CriticalRole'': From the main cast of the second campaign, [[spoiler:Caleb]] murdered both of his parents by setting their house with them inside on fire [[spoiler: under the influence of false memories.]]

* ''WebVideo/CriticalRole'', [[spoiler:Caleb]] murdered both of his parents [[spoiler: under the influence of false memories.]]

* ''WesternAnimation/TeenTitans'': Raven ''destroys'' Trigon at the end of the fourth season, and he's never seen again since then.

* Keith Keiser of ''Webcomic/TwoKinds'' killed his drunken father in self-defense 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 formed the other Bastin nation, the one without the compulsion to follow any order.]]

* ''WebVideo/CriticalRole'', [[spoiler: Caleb]] murdered both of his parents [[spoiler: under the influence of false memories.]]

!!Examples:

[[folder:Anime & 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/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.]]
* A Downplayed example in ''Manga/BlueRamun'' -- Killy is the [[PromotionToParent only caretaker]] to her sickly little brother Lau since their mother is dead and their father is an abusive drunk. Although she pleads for the Lezak orphanage to take in her brother, they refuse her because Killy and Lau's father is still alive (even though he refuses to provide for them). Killy resolves to murder her father so that the orphanage will ''have'' to care for Lau, [[spoiler: but is prevented from doing so when protagonist Jessie [[TakingTheBullet throws herself in front of Killy's blade]]. Killy's attempt scares off her dad, so in the end, Lau is accepted into the orphanage and has his treatment covered while Killy goes to prison for attacking a Blue Doctor]].
* ''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.
* ''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.
* ''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.
* In ''Manga/DemonSlayerKimetsuNoYaiba'', that is Sanemi Shinazugawa's biggest tragedy and the source for his hatred of all demons, he was leading a relatively happy humble life after his deadbeat father died, Sanemi became the man of the house, caring for his mother and all his siblings; however, one day his mother Shizu was taking too long to come down the mountain, the worst happened and so Shizu became a demon, Sanemi in pure instinctive fear ended up killing the demon that was once his mother, in self-defense, the pain from killing his own mother was coupled with the fact his little brother Genya mistaking the event as Sanemi killing their mother on purpose, calling his big bro a monster, as he didn’t realize at the moment their mother was a mindless demon.
* 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.]]
* Tsubasa of ''Manga/DestinyOfTheShrineMaiden'' killed his abusive father in defense of his younger brother Souma.
* 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 her 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.]]
* 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 into 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/DragonBall'': Goku killed his [[ParentalSubstitute adoptive grandfather]] Son Gohan through [[AccidentalMurder accidentally]] stepping on him while he was in Great Ape 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 a Great Ape, but [[AwfulTruth decide to not tell him]] -- [[spoiler:and neither does Son Gohan himself when they briefly meet, thanks to Fortuneteller Baba]]. Goku only learns the truth when he's an adult already, having learned the story of the Saiyan race from one of the Kais ''and'' having witnessed Vegeta's own transformation into a Great Ape 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.
* ''Manga/FairyTail'': [[spoiler:Sting and Rogue]] "killed" the dragons that raised them.
* 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.
* At the end of ''Anime/FullmetalAlchemistTheConquerorOfShamballa'', [[spoiler:Envy]] finally killed his father. He had been wanting to do so most of his life.
* ''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 thoroughly 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 last words, 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]].]]
* 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.]]
* ''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]] [[https://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 realized 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 a horrifying experience for the kid that he'd rather have LaserGuidedAmnesia).
* ''Manga/JoJosBizarreAdventure'':
** In ''[[Manga/JojosBizarreAdventurePhantomBlood Phantom Blood]]'', 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]]!
** Kars in ''[[Manga/JojosBizarreAdventureBattleTendency Battle Tendency]]'' also... well, forget killing his parents; he [[WhereIWasBornAndRazed killed his clan]], save for his ally Esidisi and the infants Wamuu and Santana. On the other hand, they were trying to kill him before he could put [[ArtifactOfDoom the Stone Mask]] to use.
** In ''[[Manga/JoJosBizarreAdventureSteelBallRun Steel Ball Run]]'', Diego is rumored to be a self-made ''widower'', marrying an elderly lady in her eighties before she died six months later. Unlike that first instance, a lot of people suspect Dio of killing her.
* LightNovel/{{Katanagatari}}: [[spoiler: Shichika]] is responsible for killing [[spoiler: both]] his father [[spoiler: and sister, leaving him as the last member of his clan]].
* In ''LightNovel/KinosJourney'', the king of the Coliseum Country ended up being assassinated by his son, who established the gladiator games that the country is known for. In response, the new king's son, Shizu, set out to kill him, although Kino ended up killing the king with an "accidental" shot during her match with Shizu.
* In ''LightNovel/TheLegendOfTheLegendaryHeroes'', Lucille kills his parents in order to protect his sister Ferris from them.
* In ''Manga/LudwigRevolution'''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 nearby forest. [[spoiler: She actually killed them because they had forced her into prostitution from a young age onward.]]
* 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]]...]]
* 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]].
** Also [[spoiler:Ja'far]], who [[DarkAndTroubledPast used to be]] a psychotic [[ChildSoldiers child assassin]] for the Parthevian Empire. He killed them when he was six.
* 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.]]
* Albert James Moriarty's first murders in ''Manga/MoriartyThePatriot'' were that of his mother and [[SiblingMurder younger brother]]. His father died with the servants once he burned the evidence.
* ''Manga/MyHeroAcademia'': [[spoiler:Tomura Shigaraki accidentally killed his entire family when his Quirk first activated, leaving him in the miserable state in which All For One found him. As of Chapter 222 of the manga, it's revealed that he only remembers fragments of the event, but they're enough to make him sick to his stomach.]]
* ''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.
* Played for tragedy in ''Manga/NegimaMagisterNegiMagi''. 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.
* ''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.
* [[TheEvilPrince Belphegor]] of ''Manga/Reborn2004'' 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.
* ''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 finds him in near-death in Shanghai sometime 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.
* 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...
* ''Manga/TheSeveringCrimeEdge'': Yamane killed her and Houko's parents due to being influenced 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.
* ''Manga/ShadowStar'':
** [[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.
* One of the arcs in ''Anime/{{Shigofumi}}'' involved a high school-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.
* ''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.]]
* ''Manga/ShuumatsuNoWalkureRecordOfRagnarok'': Jack the Ripper was born to a prostitute and had the ability to see people's emotions as colors. He always saw love from his mother, but it turned out that she just saw him as a tool to connect her to his father, and always thought that he'd come back for her once he became a successful playwright. After learning this, Jack kills his mother then finds and kills his father, at the same time becoming enamored with the colors of fear that are shown to him when he murders someone. This leads him to become the serial killer we all know.
* ''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.
* 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]].
* 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...]]
* 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]].
* In ''Manga/TomorrowsJoe'', [[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]].
* 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:Tetsuo]] in ''Manga/{{Yuureitou}}''. Two years prior to the series [[spoiler:he killed his adopted mother after getting into a fight with her after years of abuse]] and was DrivenToSuicide, [[spoiler:Or, so everyone thinks. 'Reiko' instead ran away, started transitioning, and began living as Tetsuo.]]
* 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 leads 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.]]

* [[spoiler:Subverted in]] ''ComicBook/{{Aquaman}}'': several people assume that Ocean Master killed his parents [[TheEvilPrince to become king]]. [[spoiler:Actually, his mother killed his father and then faked her own death.]]
* 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.
* 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/New52'' 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 anyway.
** In a look at ComicBook/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.
** Hilariously used with Batman's opposite clone, Batzarro. As the total reverse of Batman, Batzarro killed his parents and calls himself "the world's worst detective".
** 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.
** A new villain introduced in ''ComicBook/BatmanRebirth'' is "Master Bruce", aka Matthew Warner, a LonelyRichKid with a severe case of IJustWantToBeYou towards Bruce Wayne, which he took to the logical conclusion.
* In ''ComicBook/BillyMajesticsHumptyDumpty'', it is established that the Brakk brothers murdered their own mother.
* ''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 the Season 9 ''Series/BuffyTheVampireSlayer'' comics. Faith is made so angry that she chokes and almost kills her father but is stopped by Angel.
* 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.]]
* 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.
* ComicBook/EvilErnie's murder spree began with him killing both of his abusive parents.
* ''Franchise/TheFlash'':
** Evan [=McCulloch=], the second Mirror Master. 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/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 'friends' who fled and left her in the hands of a slasher.
* 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).
* 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/IncredibleHulk'':
** Another rare heroic example: Before Bruce Banner became 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.
** Narrowly averted with ComicBook/BettyRoss. She almost killed the ComicBook/RedHulk, only to realize he was her father and stop in time.
* ''ComicBook/InTheShadowOfDragons'': Kiernan is accused of killing his mother. Later he kills his own father, the real culprit.
* In the ''ComicBook/JohnConstantine'' story in ''Secret Origins'' v3 #11, one of the constants in John's MultipleChoicePast is that one of the first things he did with magic was kill his family in a fire, although this may have been a tragic accident, a brutal but justified revenge, or a ruthless act in pursuit of power. (''Constantine'' #14 had already presented it as the first one).
* ''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 [[BadPeopleAbuseAnimals 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.
* Creator/DCComics' ComicBook/{{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]]."
* ComicBook/{{Loki}} created a StableTimeLoop to ensure his biological parents would die in battle so he would be adopted by the Asgardians.
* ''ComicBook/NightmaresOnElmStreet'': Devonne killed her parents in a gas explosion.
* 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 ''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, the previous embodiment 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!
* 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/SonicTheHedgehogArchieComics'':
** 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]].
* ''ComicBook/SpiderManBlackCatTheEvilThatMenDo'': Garrison discovered he had powers when he teleported some mouthwash into his mother's heart, killing her instantly. Unlike most examples of this trope, Garrison's killing of his mother was an accident but given his complete lack of regret or remorse, he might as well have done it on purpose.
* 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).
* ''Franchise/{{Superman}}'':
** In ''ComicBook/SupermanSecretOrigin'' ComicBook/LexLuthor got his start by taking out a life insurance policy on his parents and cutting the brake lines to their car while both were taking a trip, leading to their immediate death and Luthor collecting the insurance money for start-up capital to his company.
** Subverted with ComicBook/{{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.
** In ''ComicBook/{{Crucible}}'', [[TheDragon Roho]] murders his own parents in revenge for being disowned.
* ''ComicBook/ThanosRising'': Thanos kidnaps and vivisects his mother Sui-San to find out how she could have brought someone as evil as him into the world. However, when he returns years later to wipe out the rest of his people, he leaves his father Mentor alive just so he can be witness to his son's continued atrocities.
* ComicBook/UltimateMarvel:
** ''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.
** Reed Richards had an abusive father but escaped from him to be part of the ComicBook/UltimateFantasticFour. The team broke up after ''ComicBook/{{Ultimatum}}'', and Reed had to go back home. He became the villain ComicBook/TheMaker, and his first act of villainy was to kill all his family.
** ''ComicBook/UltimateXMen'': Juggernaut crushed his father's skull in his hand when his mutant powers first manifested.
* [[Characters/NewMutants 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 conferred 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.''
* One of Marvel's ''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]].
* In Franchise/WonderWoman's [[ComicBook/WonderWoman2011 New 52 series]] Cassandra learned of her CompellingVoice when she ordered her single mother to kill herself and her mother complied.
* ''ComicBook/XMen'':
** Rahne Sinclaire, aka Wolfsbane of ''ComicBook/XFactor'' and the X-Men, 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.
** Another ''X-Men'' character, Kevin Ford/Wither, has the bad luck of his power being to dissolve any organic matter that he touches. He naturally began to freak out when his own clothes were dissolving off of his body, his father tried to comfort him and, well...
** ''ComicBook/UltimateXMen'' had an even worse example with a kid who dissolved anyone within a mile of him. He woke up to find his parents and whole neighborhood empty and wound up destroying his whole town just by wandering around trying to find somebody.
** On the topic of ''Ultimate X-Men'', ''ComicBook/UltimateOrigins'' reveals that Ultimate Magneto was responsible for the deaths of his own parents, unlike his mainstream counterpart, who lost them in UsefulNotes/TheHolocaust [[note]]Though oddly, issue 5 had Magneto claim his family died in one of humanity's periodic genocides, and imagery of the Holocaust was shown, implying this originally ''was'' meant to be a part of his backstory[[/note]].
** 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.
** 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.
** ''ComicBook/XFactor2006'' reveals that ComicBook/{{Polaris}} caused the plane crash that killed her parents due to her mutant powers manifesting and going out of control while they were arguing over her mother's affair with ComicBook/{{Magneto}}.
** ''ComicBook/RiseAndFallOfTheShiarEmpire'': Vulcan does this to his father Corsair when the latter opposes Vulcan's actions as Shi'ar Majestor. Unlike most examples on this list, Corsair came back to life later on.
* In the ''ComicBook/XWingRogueSquadron'' arc "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.

* ''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.

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...]]

* Implied in the poem ''Her Parents'', as the girl has a reason to take the loss of her parents so well and the poem specifically mentions that she's an "actress".
* ''Literature/IAmMordred'': Gawain and Garet kill their mother along with her lover when they catch them in bed together. [[spoiler: Mordred also kills Arthur in the end.]]

* 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.

** Not directly, but General Armitage Hux arranged to have his father Brendol assassinated by conspiring with Captain Phasma to poison the latter. Although Brendol's cause of death was subsequently written off as illness, the young General would claim responsibility of his father's death when he's about to execute Admiral Brooks (who was a friend to Brendol).
* 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.]]

* 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.

[[folder:Live-Action TV]]
* ''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.\\
''(later)''\\
'''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."
* ''Series/{{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/BatesMotel'': [[spoiler: It's revealed near the end of the first season that Norman killed his father during a psychotic break when Norman saw him hit his mother. Later in season four Norman kills his mother after finding out she was dating someone else, in a botched MurderSuicide.]]
* ''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. 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 older 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, who suffered severe brain damage, doesn't believe he did it. She's right: it turns out that they had moved into a house owned by another older 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 returned home to kill his own mother and father but ended up attacking the new homeowners instead.
* 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 ''[[Creator/DaveAllen Dave Allen at Large]]'', 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/DayBreak2006'': 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 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 [[Recap/DoctorWhoS30E17E18TheEndOfTime "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.]]
** [[Recap/DoctorWhoS29E8HumanNature "Human Nature"]]/[[Recap/DoctorWhoS29E9TheFamilyOfBlood "The Family of Blood"]]: Daughter of Mine is indicated to have killed the parents of the little girl whose body she stole.
** [[Recap/DoctorWhoS29E12TheSoundOfDrums "The Sound of Drums"]]: The Toclafane killed ''millions'' of their ancestors before their own birth, thanks to a "paradox machine" holding the GrandfatherParadox at bay.
** [[Recap/DoctorWhoS38E1E2Spyfall "Spyfall"]]: Daniel Barton, one of the villains, has an [[WellDoneSonGuy extremely strained relationship]] with his mother. So strained, in fact, that he hands her over to the [[EldritchAbomination Kasaavin]] to have her killed via the scrambling of her DNA.
* ''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}}'':
** Barbara Keane murdered her parents, claiming this was because they were abusive. It's left unclear if they really were, however.
** 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.
* ''Series/{{Heroes}}'':
** Sylar 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.
* ''{{Series/Inhumans}}'': Black Bolt vaporized his parents using the voice ability which he has.
* ''Series/TheJudge'': One episode focused on a mental fitness hearing for a young man claiming that he was insane when he killed his parents. However, a mental health expert immediately sees inconsistencies in his behavior and is able to expose him as a very clever actor who killed for a large inheritance. Eventually, the man is exposed and he comes out, admitting his crime. Judge Shield is very angry and orders the man held over for trial, and the assets he would have inherited given to his elderly uncle.
* 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.
* ''Series/LawAndOrderSpecialVictimsUnit'' has a few rare [[SympatheticMurderer sympathetic]] examples where the [[AssholeVictim victim]] was, or was thought to be, an {{Abusive Parent|s}}, and is killed either by the child they were abusing or by one sibling trying to protect another.
* Parker from ''Series/{{Leverage}}'' certainly seems to be a case. In flashback, we see 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 Dharma 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.
* ''Series/LukeCage2016'': Tilda ends up poisoning her mother Mariah.
* 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|2008}}'': her mother and the man she believed was her father were already dead, but she gave Agravaine an 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/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 Peter Pan ''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 Fiona, 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.
** Cruella de Vil tells the Author that her mother is a BlackWidow who's [[AbusiveParents kept her locked up in the attic]] to keep her from telling the truth. Her ''mother'' on the other hand tells the Author that Cruella was TheSociopath from the beginning and killed first her father, then her mother's next two husbands, and was locked up to keep her from harming anyone else. ''This'' is the actual truth, as the Author finds out when Cruella uses the magic powers he gave her to kill her mother, who'd been protected by dogs until Cruella could control them.
* ''Series/APrinceAmongMen'': Episode 3 gives us John the Murderer, who deliberately pushed his parents into the River Mersey. Understandably, Prince doesn't to be anywhere near the guy.
* ''Series/TheSinner'':
** The second-season premiere opens with a young boy poisoning his parents. [[spoiler: It turns out they aren't, though.]]
** [[spoiler: As a child, Harry set fire to his house in the hopes that he would be rid of his abusive mother. At the very least, he succeeded in having her lose custody of him.]]
* ''Series/{{Scrubs}}'': The episode ''My Saving Grace'' jokingly implies [[DrJerk Dr Cox]] murdered his AbusiveParents.
* 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 the 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 absence, she has become an EnfantTerrible and the little girl strangles and kills her father when he tries to save her and declares her loyalty to Anna.
* 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.
* 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.
[[/folder]]

[[folder: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]].]]
* Tasha Godspell's sister in ''Manhwa/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.
[[/folder]]

[[folder:Video Games]]
* 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. You can see where this is going.
-->'''Calendar Man:''' '''M''' was for the '''m'''urderous look she gave me.\\
'''O''' meant '''o'''nly she was weak and '''o'''ld.\\
'''T''' is for her '''t'''error as she fought me.\\
'''H''' is for '''h'''er '''h'''eart that I now '''h'''old.\\
'''E''' is for her '''e'''yes swiftly dimming.\\
'''R''' means '''r'''ot, and soon '''r'''otting 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.\\
\\
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.
* In ''VideoGame/BatmanTheTelltaleSeries'', Lady Arkham (a.k.a. [[spoiler:[[CanonCharacterAllAlong Vicki]] [[AdaptationalVillainy Vale]]]]) killed her [[AbusiveParents abusive foster parents]], and had a damn good time doing it too from how the crime scene looks.
* ''VideoGame/TheBlackHeart'': [[EnfanteTerrible Peketo]] [[KickTheSonOfABitch murdered his]] [[AbusiveParents alcoholic and physically abusive father]]. That was ''before'' he killed 6 innocent bystanders just for the hell of it.
* 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/ChzoMythos'':
** It was said that [[EldritchAbomination 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]].
* ''VideoGame/CliveBarkersUndying'': [[spoiler:Ambrose]] beats his father to death with a pool cue, tired of him meddling in his affairs.
* In ''VideoGame/DanganronpaAnotherEpisodeUltraDespairGirls'' The [[spoiler:Warriors of Hope (Masaru, Kotoko, Jataro, Nagisa and Monaca)]] admit to [[KickTheSonOfABitch having murdered]] their AbusiveParents prior to the events of the game.
* In ''VisualNovel/Danganronpa2GoodbyeDespair'', [[spoiler: Makoto states that as [[BrainwashedAndCrazy Remnants of Despair]], some of the cast murdered their own parents and other loved ones. [[Anime/Danganronpa3TheEndOfHopesPeakHighSchool The anime]] confirms this was the case for [[TheEvilPrincess Sonia]] and [[TheDon Fuyuhiko]], at least.]]
* ''VideoGame/DevilMayCry3DantesAwakening'' 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...
* ''VideoGame/DeadInVinland'' has a surprising example in [[spoiler: Brother Angelico, who seems like a gender inversion of the WhiteMagicianGirl but actually murdered his abusive father in a dissociative state, then the rest of his family, then continued as an AxCrazy SerialKiller who doesn't remember his crimes.]]
* 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.
* A tragic example in ''VideoGame/Fallout4'' is [[spoiler: Cait]]. As you come to know her, she’ll tell you that her parents abused her until she was old enough to be sold into slavery. She would pickpocket the raiders that owned her when they were asleep until she had enough to buy her freedom, then she tracked down her parents and murdered them.
* 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 atonement 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 Albein 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 climactic battle against Rudolf, and naturally ''[[HeroicBSOD he doesn't take it well]]''.]]
** In ''VideoGame/FireEmblemGenealogyOfTheHolyWar'':
*** In the first half, King Chagall of Augustria and Duke Andrey of Jungby kill their fathers to ascend to their respective thrones. (The second earns the scorn of [[EvenEvilHasStandards his fellow conspirator Duke Lombard]] for that.) Also, for major VideoGameCrueltyPotential, in both halves the player can have some of their own units kill their {{Archnemesis Dad}}s: Tailtiu (daughter of Duke Reptor) and Lex (son of the aforementioned Duke Lombard) for the first part, either Iuchar or Iucharba (sons of King Danann) in the second.
*** In the second half, there's [[spoiler:the [[DemonicPossession Loptous!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.]]
** In the backstory of ''VideoGame/FireEmblemTheBindingBlade'', [[spoiler:after numerous attempts on his own life from [[OffingTheOffspring his father, King Desmond]], Prince Zephiel of Bern [[TheDogBitesBack decided to turn the tables]]. He faked his own death, then at his funeral, when Desmond opened the coffin to check on his son, Zephiel stabbed him dead on the spot.]]
** The BigBad of ''[[VideoGame/FireEmblemPathOfRadiance 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 ''[[VideoGame/FireEmblemRadiantDawn 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 is possessed by the BigBad and views this as a MercyKill. And to be fair, the BigBad killed the other parent in the [[spoiler:first]] case ([[spoiler:while possessed]]).
** ''VideoGame/FireEmblemFates'':
*** Several characters can kill their parents: [[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.]]
** ''VideoGame/FireEmblemThreeHouses'':
*** This happened in the backstory of [[spoiler: Mercedes and Emile/Jeritza/the Death Knight]]. The latter [[BerserkButton went ballistic]] when he heard his father had found [[spoiler: Emile's]] mother and half-sister who fled their terrible treatment, and intended to drag them back and this time [[AndNowYouMustMarryMe force a marriage]] on [[MySisterIsOffLimits said half-sister]] since she's younger and [[StalkerWithATestTube more likely to give him more Crest-bearing heirs]]. [[spoiler: Emile slaughtered his father's entire noble house, renounced his name, and developed a homicidal split personality called the Death Knight.]]
*** It's possible for you to have Ashe kill his adoptive father Lonato in Chapter 3.
*** Likewise, it's possible for Annette to kill her father, Gilbert, if you recruit her to the Black Eagles house [[spoiler:and then side with Edelgard during Chapter 11. You end up fighting Gilbert in the final mission of the Crimson Flower route, and can kill him there.]]
*** Offscreen during the events of Chapter 11, [[spoiler:Hubert assassinates his father, the former Marquis Vestra, for betraying the Adrestian crown in the Insurrection of the Seven]].
* 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/GodOfWarIII'', 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 killed her ZombieInfectee father on his orders after he was bitten by his zombie ex-wife, because he wanted to [[DyingAsYourself die as himself]] rather than become a zombie. Zoey and the other playable characters are later informed by the military that they are [[TyphoidMary asymptomatic carriers]] of the zombie infection... and also that the carrier gene is hereditary. Since Zoey's mother obviously didn't have it, that leaves only one other option. Zoey breaks down in tears at the revelation that [[SenselessSacrifice she killed her father for no reason]].
* 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 ''VideoGame/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 as 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]].
* ''VideoGame/{{OFF}}'': This technically happens at the end of the game, with [[spoiler:the Batter murdering Hugo, who had created him.]]
* 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/Persona5Strikers'', [[spoiler:Akira Konoe]] killed his [[AbusiveParents abusive father]] and made it seem as though a burglar had done the deed.
* 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.
** Downplayed with Kuki Tohma, he was born an orphan and was adopted by the Greater Kuki. But because of his jealousy towards Seishiro, Tohma murdered the old man and stole his red katana, which was said to grant its owner greater strength, for himself and became the power-hungry bad guy that sets the events of ''Warriors Rage'' in motion.
* ''VideoGame/{{Shadowverse}}'': According to the flavor text, Harnessed Flame killed her own mother in the belief that it would protect Harnessed Glass, who in turn froze their father to protect Flame.
* 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.]]
* Happened more than once in ''Franchise/StreetFighter'':
** [[VideoGame/StreetFighterII Vega's]] quite unattractive father murdered his own wife on suspicion of infidelity. Vega returned the favor, and now you understand why he's completely nuts when it comes to beauty.
** After being brainwashed thoroughly and made into [[BodyguardBabes one of the Dolls]], [[VideoGame/StreetFighterAlpha Juni's]] first mission was going back home and killing her parents. [[https://static.wikia.nocookie.net/streetfighter/images/4/40/Juni.jpg/revision/latest 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 [[MythologyGag 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 rumors 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 for 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]].
* ''VideoGame/{{Warcraft}}'':
** Arthas Menethil. 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 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.]]
** Jaina Proudmoore is a rare non-evil example, justified by her father's attempted genocide. While she didn't strike the killing blow herself, the nation of Kul Tiras essentially disowned her for her involvement in Daelin's death.
* ''VideoGame/{{Warframe}}'': When a colony ship was lost in the [[HyperspaceIsAScaryPlace Void]] after an experimental Void-jump, all the children gained strange Void powers, but all the parents were [[AxeCrazy driven insane]] (or possibly [[DemonicPossession possessed by something]]; it's unclear). The children had to kill their parents to survive. [[spoiler:These children eventually became the Tenno]].
* In ''VideoGame/WolfensteinIITheNewColossus'', [[spoiler:B.J. Blazkowicz]] confronts and kills his father midway through the game. Though said father was an [[AbusiveParents abusive]], [[KickTheDog dog-kicking]] and [[MoralEventHorizon -raping]], Nazi-sympathizing asshole who shamelessly sold out ''his own Jewish wife'' to the aforementioned Nazis, so he had it coming.
-->'''[[spoiler: B.J. Blazkowicz]]''': Was a time I was scared of you. Was a time I'd have pissed myself having a gun pointed at my head. [[TranquilFury You know what I feel right now?]] [[PreMortemOneLiner Not a goddamn thing]].

* Jeremy Bamber murdered his parents, his schizophrenic sister (who he then attempted to frame), and her twin six-year-old sons [[InheritanceMurder to secure an inheritance]]. Instead he was sentenced to life imprisonment under a whole-life order.
* 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 in court.
* Caril Ann Fugate, the teenage girlfriend of 1950s 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 to 22 years after a plea deal. He'll be out on 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 filmmaker 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 ax 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. 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 stab her. According to legend, when she saw the guard with his sword drawn, she said, ''Ventrem feri''--"Strike at my womb."
* In Amityville, Long Island, New York, Ronald [=DeFeo=] Jr. shot and killed his parents and four siblings in bed on November 13, 1974, at 3:15 am.
* 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 and Creator/MelanieLynskey starred as the girls. Ironically, Hulme became a murder mystery writer after adopting the name Anne Perry when she was released.
* 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, his two siblings, and five other relatives, before shooting himself in the head. He would take a few days to die, but not before being proclaimed King of Nepal while in a coma. 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. The theory persists even though Gyanendra's own wife, Komal, was wounded in the massacre.
* 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" Blanchard 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]].
* In the Spring of 2001, 17-year-old [[SpoiledBrat Natalie DeMola]], along with her boyfriend and his friend, killed her mother Kim because she had enough of [[MamaBear her overprotection]] and tried to make it look like a home invasion gone wrong. They probably would have gotten away with it upon speeding away from the crime scene had they not had a traffic collision with ''[[WhatAnIdiot the district attorney's car.]]'' They all received life sentences.
* On Easter Sunday 1992, wealthy Californian college student Dana Ewell hired his two friends to shoot and kill his parents, Dale and Glee, and his older sister, Tiffany, to get his hands on their vast inheritances. While the men were able to easily kill his father and sister, his mother tried to run only to be chased down and finished off. All three men were eventually sentenced to life terms.
* Attempted but ultimately subverted with a Florida teenager, Jacqueline "Nikki" Reynolds in 1997. To wit, she was adopted by a loving Christian Fundamentalist couple as a baby, but grew into a rebellious/mentally ill teenager and began to date a boy who the parents did not approve of.[[note]]but overall was ''not'' a bad guy; they disliked him due to him not being a good student and not having the same Christian standards that they shared. Even the night of the crime, he called Nikki's mother and apologized for all of the grief their past relationship had produced; she completely understood, even admitting that it was her ''daughter'' all along, who had grown obsessed with him to the point of even lying about being pregnant by him, who was the real cause of the problems[[/note]] She soon believed that all of her problems would go away if she killed her mother then and there, kill the father after he came home from church and go to school the next day and kill her ''ex-boyfriend'', but after brutally stabbing her mother and her eventually succumbing to her injuries, she regretted her actions and couldn't bring herself to carry out the other murders. She was sentenced to life the following year and her father and ex-boyfriend cut ties with her permanently.
* In October 2007, Daniel Petric shot his parents for [[DisproportionateRetribution denying him access to the latest "Halo" video game.]][[note]]He had the game because he had suffered an injury that gave him a staph infection which permanently stopped him from playing sports and he ended up getting safer video games and after getting ''Halo'' and his parents learning the true nature of the game, got rid of it[[/note]] He then fled and told police that it was a MurderSuicide with his father, a ''pastor'', shooting his wife and then himself. Instead, the [[MadeOfIron father survived]], the boy eventually admitted to what he did, and he ultimately forgave his son and he was sentenced to life with the possibility of parole in 25 years.
* The [[https://en.wikipedia.org/wiki/Rayleigh_bath_chair_murder Rayleigh bath chair murder]], in which a soldier, fed up with his abusive father, killed him by way of [[ThereIsNoKillLikeOverkill an anti-tank mine hidden in his wheelchair]].
[[/folder]]

* ''Literature/SimonArk'': In "The Treasure of Jack the Ripper", having exposed the murderer, Simon goes to say that her first victims were almost certainly her parents, who died a house fire when she was 12.

* Creator/DCComics' SelfDemonstrating/{{Lobo}} is not only a self-made orphan but a self-made LastOfHisKind. As he put it in his appearance on ''WesternAnimation/SupermanTheAnimatedSeries'':

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.

* 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 on the book claimed aren't real, though; just the crime.

** 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 Downplayed example in ''Manga/BlueRamun'' -- Killy is the [[PromotionToParent only caretaker]] to her sickly little brother Lau, since their mother is dead and their father is an abusive drunk. Although she pleads for the Lezak orphanage to take in her brother, they refuse her because Killy and Lau's father is still alive (even though he refuses to provide for them). Killy resolves to murder her father so that the orphanage will ''have'' to care for Lau, [[spoiler: but is prevented from doing so when protagonist Jessie [[TakingTheBullet throws herself in front of Killy's blade]]. Killy's attempt scares off her dad, so in the end Lau is accepted into the orphanage and has his treatment covered while Killy goes to prison for attacking a Blue Doctor]].

* 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]].]]

** Also, after [[spoiler:Yukishiro Tomoe's]] death, her ''very'' mentally unstable little brother [[spoiler:Enishi]] is saved by a wealthy Japanese family who finds him in near death in Shanghai sometime 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.

* 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.

* 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.

** 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.

* Subverted in the Season 9 ''Series/BuffyTheVampireSlayer'' comics. Faith is made so angry that she chokes and almost kills her father, but is stopped by Angel.

** In ''ComicBook/SupermanSecretOrigin'' ComicBook/LexLuthor got his start by taking out a life insurance policy on his parents and cutting the break lines to their car while both were taking a trip, leading to their immediate death and Luthor collecting the insurance money for start up capital to his company.

** Reed Richards had an abusive father, but escaped from him to be part of the ComicBook/UltimateFantasticFour. The team broke up after ''ComicBook/{{Ultimatum}}'', and Reed had to go back home. He became the villain ComicBook/TheMaker, and his first act of villainy was to kill all his family.

* 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]].

* ''Fanfic/{{SAPR}}'': Cinder burned her home to the ground with her stepmother and one of her stepsisters inside. Then years later during the course of the story she stabs her other stepsister to death in a dark alley.

* 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.

* The killer in ''Film/{{Mindhunters}}'' when he was just a lad. He assumed the police would take him away when they investigated the scene, but to his astonishment nobody even suspected him of causing his parents' deaths, which just fed his misantropy even more.

* In ''Film/Scream3'', it's revealed that [[spoiler:Sidney has a half-brother named Roman Bridger, who was conceived when their mother Maureen was gang-raped by [[HorribleHollywood a number of movie producers]]. Roman tracked down Maureen years later, but was rejected by her. He then stalked her for months, learning she'd had affairs with a number of men in Woodsboro, and orchestrated her murder by using [[Film/Scream1996 Billy Loomis (and by extension Stu Macher)]] as a proxy. During the film proper, Roman murders John Milton, [[MamasBabyPapasMaybe one of the producers who participated in Maureen's gang-rape]], as his last victim.]]

* In ''Film/TheYoungPoisonersHandbook'', Graham kills his stepmother by poisoning her with thallium, and is in process of killing his father the same way when he is arrested.

* 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.

** 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.

* One episode of ''Series/{{CSINY}}'' featured [[VictimOfTheWeek an older 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, who suffered severe brain damage, doesn't believe he did it. She's right: it turns out that they had moved into a house owned by another older 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 returned home to kill his own mother and father, but ended up attacking the new homeowners instead.

** [[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.]]

* 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]].

* 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.

** "Who You Gonna Call?" discusses a college age kid who killed his family, starting with his parents.

* 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/DeadInVinland'' has a surprise example in [[spoiler: Brother Angelico, who seems like a gender inversion of the WhiteMagicianGirl but actually murdered his abusive father in a dissociative state, then the rest of his family, then continued as an AxCrazy SerialKiller who doesn't remember his crimes.]]

** 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 Albein 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]]''.]]

*** This happened in the backstory of [[spoiler: Mercedes and Emile/Jeritza/the Death Knight]]. The latter [[BerserkButton went ballistic]] when he heard his father had found [[spoiler: Emile's]] mother and half-sister who fled their terrible treatment, and intended to drag them back and this time [[AndNowYouMustMarryMe force a marriage]] on [[MySisterIsOffLimits said half-sister]], since she's younger and [[StalkerWithATestTube more likely to give him more Crest-bearing heirs]]. [[spoiler: Emile slaughtered his father's entire noble house, renounced his name, and developed a homicidal split personality called the Death Knight.]]

* ''VisualNovel/HigurashiWhenTheyCry'': [[spoiler: Satoko, under the effects of Hinamizawa Syndrome, believed her mother/stepfather were planning to kill her, and pushed them both over a cliff in self-defense.]]

* [[spoiler: Carolina]] from ''Machinima/RedVsBlue'' sets out in Season 10 to kill [[spoiler: The Director]] for casting [[spoiler:her]] and the team aside, causing them to fragment and turn on one another, all in the name of reviving [[spoiler: her mother and his wife, Allison]] who had died during the Human-Covenant war. [[spoiler: Carolina finds the Director, a sad and broken man at the end of the season and she forgives him of all he’s done. Before she leaves however, he asks she [[LeaveBehindAPistol leave him with her pistol]], with which he [[DrivenToSuicide commits suicide]].]]

* ''WesternAnimation/FinalSpace'': In the Season 2 episode "The Grand Surrender", we learn that Ash accidently killed her own parents (and several other bystanders) when her powers first manifested after she saw her sister getting sacrificed to the Serpent God Werthrent.

* [[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.

* [[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.

* 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.

What might be considered the inverse of OffingTheOffspring, and is 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 or princess]] can also do that if they’re impatient enough. It's the ultimate mark of an EnfantTerrible, AntagonisticOffspring, or the AbusiveOffspring, the end result of a BetrayalByOffspring, and a likely origin of an EvilOrphan (who may also be [[AbusiveOffspring abusive]]).

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.
