* ''VideoGame/BlazBlue''. Carl Clover, a young boy who's innocent and cheery, was deeply traumatized when it turns out his father Relius nonchalantly turned his sister Ada into a Nox Nyctores, a mechanical doll known as Nirvana... and it was incomplete, and he just left the incomplete Nirvana for Carl to finish. This event caused Carl to become extremely bitter to both the world and adults in general. Making matters worse, the next time he met Relius, he found out that Relius did the same to Carl's mom, Relius' wife, Ignis, and ''still'' with the same nonchalant attitude of ForScience.

* Strongly hinted to be the case in ''VisualNovel/UminekoWhenTheyCry'' with [[spoiler:Battler's parents, Rudolf and Kyrie who take the chance when the gold is found and kill everyone except Battler and Eva.]]

* ''WesternAnimation/HarleyQuinn2019'': After [[YankTheDogsChain seemingly reconciling]] with her parents, it goes straight out the window when it's revealed [[spoiler:that they want to kill Harley for a $1 million bounty.]] Harley is [[EvenEvilHasStandards so disgusted]] she doesn't even bother to kill them.

* ''Fanfic/HuntersOfJustice'' sees Jacques Schnee hand Willow and Whitley, his own wife and child, over to [[BigBad Brainiac]] so the AI can learn the secrets of their hereditary Semblance.

* In ''Series/KamenRiderDrive,'' we get a doozy. [[spoiler: Kiriko and Gou's father, Professor Banno, was one of the creators of this year's villains, the Roidmudes, but it was always assumed that it was a case of AIIsACrapshoot. Nope, Banno is basically [[Series/DoctorWho Davros]]; the Roidmudes' current state is his deliberate doing, and the Heart Roidmude, the BigBad until that point, was horribly abused by him and basically a case of TheDogBitesBack. Banno betrays the SCU and his own children, lets us know he sees even his own children as a means to his dark but as-yet-not-fully-understood ends, and rises to the role of BigBad. Right now, dealing with him is ''everyone's'' main concern, good guys and bad guys alike.]] HumansAreTheRealMonsters, indeed!
* In ''Series/{{Lost}},'' Anthony Cooper strikes up a father-son relationship with Locke in order to steal his kidney, then unceremoniously dumps him.

---> Your presence does not surprise me, Assassin. I have known of you ever since your craft entered the Eastern Fringes. Why did I not have you killed? Because your mission and the act you are about to commit proves the truth of all I have ever said or done. I merely punished those who had wronged, just as your false Emperor now seeks to punish me. Death is nothing compared to vindication.

%%* ''Series/{{Justified}}'': Arlo betrays Raylan several times. (Zero-Context: Who are Arlo and Raylan and how does the former's betrayal fit into this trope?)

* Anthony Cooper from ''Series/{{Lost}}'' strikes up a father-son relationship with Locke in order to steal his kidney, then unceremoniously dumps him.

** The ''[[ComicBook/GrantMorrisonsBatman Batman R.I.P.]]'' comics storyline toys with the possibility that the villain responsible for the defining tragedy in Bruce Wayne's life was [[spoiler: Thomas Wayne, who had his wife Martha killed while faking his own death]]. However, the conclusion of the story kinda seems to confirm that someone was just messing with Bruce in the end.

* Strongly hinted to be the case in ''VisualNovel/UminekoWhenTheyCry'' with [[spoiler:Battler's parents, Rudolf and Kyrie who takes the chance when the gold is found and kills everyone except Battler and Eva.]]

* TheReveal in ''Film/TheGeneralsDaughter''. The general [[spoiler:covered up his own daughter's gang-rape]] to protect the reputation of West Point and to secure a promotion for himself. This betrayal hurt his daughter more than [[spoiler:the rape ever did]]. She was so miserable that the investigators told her father that [[spoiler:he was the one who truly murdered his daughter -- the guy who shot her had merely put her out of her misery]].

* ''Film/MouthToMouth'': She's not evil, but Sherry's mother ends up joining the cult instead of trying to get her daughter to leave. Even after Sherry realizes how screwed up everything is (partly due to her mother agreeing with everyone else to punish her for no good reason) and decides to leave, her mom stays.

* In the ''Literature/GreyGriffins'' books, Max's father turns out to be evil and wishes to use Max to gain access to a world-destroying artifact. He has no qualms about killing his own son and his son's friends - genuinely shocking to Max, since he doesn't get along with his mom, and had always preferred his dad.

** ''ComicBook/ADeathInTheFamily'': [[http://asylums.insanejournal.com/scans_daily/235391.html#cutid1 Jason Todd]] has had horrible luck with his mom too]]. After finding out that the mother who raised him was not his biological mother, Jason sets out across the globe searching for his birth mother. Eventually, Jason is reunited with her; however, his mother is evil. There is really no other way to describe a woman who would so willingly and suddenly betray her 15-year-old-son to the Joker to cover up her crimes and actually stand there watching him be beaten brutally to near-death with a crow bar, all the while looking none too fazed. After all this happens, [[ChronicBackstabbingDisorder the Joker betrays her]], ties her up and leaves her and Jason in a room with a bomb. Jason, injured though he is, tries to save the mother who just betrayed him. He cuts the ropes binding her and together they make it to the door. Naturally, the door is locked. The bomb explodes, Jason and his mother die. He got better. She didn't.

** Bruce's son Damian hasn't been much luckier. He wasn't at all pleased when his mother Talia willingly allowed Slade to control his body by means of implanting a device in his spine. And when he supported Dick and Bruce's ideals rather than her's, he found out that Talia had [[spoiler: actually created another clone of Damian because he wasn't "perfect enough"]]. Then she kicked him out from the house of Al Ghul and told him not to come back, while all Damian wanted was some of his mother's love. JerkAssWoobie indeed. This culminates in [[spoiler:Damian's death at the hands of his own clone. He even pleads with his mother to call off the attack, but she does nothing as the clone impales her own son on a sword.]]

Eventually Jason is reunited with her; however, Jason's mother is evil.

** In a a variation. Dinah Lance saw that Sara was going to join Oliver on the ''Queen's Gambit'' and realized she was sleeping with her sister's boyfriend. After some initial attempts to talk Sara out of it, she let Sara go through with it effectively allowing her to betray Laurel and betraying Laurel herself through inaction. To make matters worse, she didn't even come clean about when the ship sank and only admitted it years later.
** A stronger example would be Moira Queen. Soon after he returns from being stranded on an island for 5 years after witnessing his father's suicide, Moira has her son, Oliver, kidnapped and interrogated to find out if his father, Robert, had revealed any secrets before his death. Unfortunately for Moira, Oliver is now a [[ComicBook/GreenArrow superhero]] and is able to escape without revealing anything.

*** Drugs Thea, [[spoiler:his illegitimate daughter]], and gets her to [[spoiler:kill Sara Lance]] in order to distract [[spoiler:the League of Assassins]] who want him dead, knowing that [[spoiler:Sara and Nyssa Al'Ghul were lovers]] and that this would cause [[spoiler:the League of Assassins]] to descend on Star City for revenge. It is a BatmanGambit because Malcolm knows that Oliver will intercede to save his little sister. The only way to settle it is a fight to the death. If Oliver dies, his death settles the blood debt, and Malcolm is no worse off than he began. If Oliver survives and kills [[spoiler:R'as Al-Ghul]], Thea's blood debt is cleared and the leader of [[spoiler:the League]] that wants revenge on Malcolm is dead and his grudges along with him.

** An episode has a model die during the shooting of a reality TV show on a base, only for Gibbs and Co. discover that the man responsible was her agent who, while not biologically related, had adopted her as a teenager. The woman had begun a relationship with a sergeant and was going to give up modelling to be with him.

* In ''Series/SonsOfAnarchy'' Gemma continually does underhanded things to undermine her son, Jax's, relationship with his girlfriend and eventual wife, Tara. Gemma explicitly says that Tara was Jax's first love, that he was heartbroken the first time they broke up, and that he would do anything for her, making Tara the only person who has a strong enough influence on Jackson to overpower Gemma's own overbearing, manipulative influence on him. Jax loves his mom and is none the wiser to her manipulations. Gemma is so determined to control Jax that she eventually [[spoiler:murders Tara]] a move that emotionally destroys Jackson, leads to him [[spoiler:murdering Gemma in retaliation]] before [[spoiler:dying of suicide to atone for all the murders he committed trying to avenge Tara's murder]].

* Gaia of Myth/GreekMythology did this to three generations' worth of her divine progeny after they pissed her off by empowering the next generation. Her first son Uranus [[ParentalIncest who was also her first consort]] was jealous and fearful of their children the Titans and trapped them inside Gaia. A pissed off Gaia forged a huge sickle and gave it to her youngest son Cronus and had him ''[[GroinAttack castrate]]'' Uranus with it. Cronus eventually turned out to be similar to Uranus and trapped his non-Titanic siblings, the Hechatonchaires and the Cyclopses, inside Gaia since he feared their power. Cronus knew that Gaia would try to turn his own children against him in revenge, so he ''ate his own children after they were born.'' A pissed off Gaia conspired with Cronus' wife Rhea to save the last child Zeus and raised him to be a LaserGuidedTykeBomb against his father. After Zeus and his fellow Olympians eventually prevailed, they stuck the Titans who refused to surrender to them in the deepest pits of Tartarus, which upset Gaia since she didn't want her children to suffer such a horrible punishment. A pissed off Gaia then sent various giant monsters such as her youngest and strongest offspring [[EldritchAbomination Typhon]] to overthrow the Olympians. This chain of betrayal ended when Zeus and the Olympians defeated the threats sent by Gaia, proving that they had surpassed her.

* ''WesternAnimation/HarleyQuinn2019'': After [[YankTheDogsChain seemingly reconciling]] with her parents, it goes straight out the window when its revealed [[spoiler:that they want to kill her for a 1 million bounty.]] Harley is [[EvenEvilHasStandards so disgusted]] she doesn't even bother to kill them.
* In ''WesternAnimation/TheLegendOfKorra'' it turns out that [[spoiler:Hiroshi Sato]] is an Equalist. The traditional "WeCanRuleTogether" spiel is given, but the child violently refuses. [[spoiler:Culminates in an attempt at ''OffingTheOffspring'' in the finale when Asami claims that Hiroshi doesn't love her late mother anymore since he's too full of hatred. Hiroshi declares that she's beyond "saving" and seriously tries to murder her. Bolin rightly calls Hiroshi a horrible father, and Asami agrees.]]

* In ''Series/KamenRiderDrive,'' we get a doozy. [[spoiler: Kiriko and Gou's father, Professor Banno, was one of the creators of this year's villains, the Roidmudes, but it was always assumed that it was a case of AIIsACrapshoot. Nope, Banno is basically Davros; the Roidmudes' current state is his deliberate doing, and the Heart Roidmude, the BigBad until that point, was horribly abused by him and basically a case of TheDogBitesBack. Banno betrays the SCU and his own children, lets us know he sees even his own children as a means to his dark but as-yet-not-fully-understood ends, and rises to the role of BigBad. Right now, dealing with him is ''everyone's'' main concern, good guys and bad guys alike.]] HumansAreTheRealMonsters, indeed!

* ''Series/HouseOfAnubis'' done by Mr. Sweet- Eddie's father. A bit of dramatic irony, too, as the viewers and the rest of Sibuna knew that Mr.Sweet was a member of Team Evil but nobody told Eddie, and when he found out he was completely devastated. Gets even worse after Mr.Sweet starts proactively manipulating Sibuna to further the plans of his own team-- and knowingly hurting Eddie in the process.

** Mortarion was raised by a barbarian warlord, one of the few adapted to their homeworld's poisonous atmosphere. Those who could survive the mountain fogs regularly preyed on the regular humans living in the unpolluted areas, Mortarion eventually rebelling against his adoptive father and joining them. When the Emperor arrived, he allowed Mortarion a single chance to carry out his vendetta, intervening when the fog proved too much even for the Primarch. Mortarion later believed the Emperor had become just another tyrant like the man who'd raised him (their views on the Warp being diametrically opposed didn't help matters), joining horus once he rebelled.

* This is the premise of Marvel's ''ComicBook/{{Runaways}}''. Children learn that their parents are supervillains, and run away from home, fearing they would otherwise grow up to be like them.

* ''Fanfic/BlackbirdArrow'': Dinah already had this with her canon decision to let Sara sleep with Laurel's boyfriend; but when she gave Laurel to the League of Assassins so they'd release Sara, she gave this trope an ugly new face.

* ''Fanfic/WrongRoadToTheRightPlace:'' When Oliver learns that Dinah let Sara get on the ''Queen's Gambit'' to sleep with him, he outright tells her she betrayed Laurel. The fact that she needed to be told it was a betrayal just makes it worse.

* ''VisualNovel/{{Tsukihime}}'': There would be no Far Side routes if this wasn't the case for Shiki/Akiha. [[spoiler:Foster father, sure, but considered to be his father more than Kiri Nanaya is except by his doctor.]]

* The ''[[ComicBook/GrantMorrisonsBatman Batman R.I.P.]]'' comics storyline toys with the possibility that the villain responsible for the defining tragedy in Bruce Wayne's life was [[spoiler: Thomas Wayne, who had his wife Martha killed while faking his own death]]. The conclusion of the story kinda seems to confirm that someone was just messing with him in the end.
** [[http://asylums.insanejournal.com/scans_daily/235391.html#cutid1 Jason Todd]], as you know, [[ComicBook/ADeathInTheFamily had horrible luck with his mom too]]. After finding out that his mother who raised him was not his biological mother, Jason sets out across the globe searching for his birth mother. Eventually Jason is reunited with her; however, Jason's mother is evil. There is really no other way to describe a woman who would so willingly and suddenly [[http://i30.tinypic.com/2nr1xy1.jpg betray her fifteen year old son]] to [[http://i26.tinypic.com/dlsveo.jpg the Joker]] and [[http://i27.tinypic.com/2vwzd76.jpg actually stand there watching him be beaten brutally to near death with a crow bar]], all the while looking none too fazed. After all, this happens, [[ChronicBackstabbingDisorder the Joker betrays her]], ties her up and leaves her and Jason in a room with a bomb. Jason, injured though he is, tries to save the mother who just betrayed him. He cuts the ropes binding her and together they make it to the door. [[http://i25.tinypic.com/28jzewg.jpg Naturally the door is locked.]] The bomb explodes, Jason and his mother die. He got better.
*** The worst part about all of this is that whenever Jason's death is brought up, his mother is ''never'' mentioned. Jason's always blamed for his own death. Granted, nobody else besides the Joker knew that she betrayed Jason and led him into a trap, but it gets to the point where you wonder if even ''Jason himself'' remembers what actually happened.
*** Jason believes that Bruce is guilty of this. Even after Jason's death, he ''still'' keeps letting the Joker live, and eventually replaced Jason with another Robin. It's not hard to see his viewpoint since the Saviour of Gotham apparently was ready to replace his dead son & partner without even bringing the killer to "justice".
** And Bruce's son Damian hasn't been much luckier. He wasn't at all pleased when his mother Talia willingly allowed Slade to control his body by means of implanting a device in his spine. And when he supported Dick and Bruce's ideals rather than his Talia's, [[spoiler: he found out that Talia had actually created another clone of Damian because he wasn't "perfect enough".

She was so miserable that the investigators told her father that he was the one who truly murdered his daughter -- the guy who shot her had merely put her out of her misery.]]
* In ''Film/HotFuzz'', it turns out the mastermind behind all the 'accidents' is [[spoiler:Frank Butterman, father of Danny Butterman, one of the two protagonists]].

* ''Film/RepoTheGeneticOpera'': Nathan, although the reveal comes immediately after the first scene with him.

* Played straight and then inverted in ''Series/{{Angel}}'s'' final season episode "[[Recap/AngelS05E07Lineage Lineage]]". Roger Wyndam-Pryce, Wesley's father. It turns out he intends to steal Angel's free will. Then it turns out he was a robot (which was shot by Wesley ''before'' the revelation).
* ''Series/{{Arrow}}'' has a variation. Dinah Lance saw that Sara was going to join Oliver on the ''Queen's Gambit'', and realized she was sleeping with her sister's boyfriend. After some initial attempts to talk Sara out of it, she let Sara go through with it effectively allowing her to betray Laurel and betraying Laurel herself through inaction. To make matters worse, she didn't even come clean about when the ship sank and only admitted it years later.

** Also, [[ArchnemesisDad Malcolm Merlyn]]:
*** Spends much of the first season fighting both Oliver and his alter ego, The Hood, despite Oliver being his son's best friend since childhood and Malcolm being aware that Oliver is The Hood.
*** Causes the death of his own son because of his own son, Tommy, who dies when he's crushed in a building destroyed by Malcolm's [[MisplacedRetribution Undertaking Earthquake Machine]] designed to level the entire section of the city in which his wife was murdered.
*** Drugs Thea [[spoiler:,his illegitimate daughter,]] and gets her to [[spoiler:kill Sara Lance]] in order to distract [[spoiler:the League of Assassins]] who want him dead, knowing that [[spoiler:Sara and Nyssa Al'Ghul were lovers]] and that this would cause [[spoiler:The League of Assassins]] to descend on Star City for revenge. It is a [[BatmanGambit Batman Gambit]] because Malcolm knows that Oliver will intercede to save his little sister. The only way to settle it is a fight to the death. If Oliver dies, his death settles the blood debt, and Malcolm is no worse off than he began. If Oliver survives and kills [[spoiler:R'as Al-Ghul]], Thea's blood debt is cleared and the leader of [[spoiler:The League]] that wants revenge on Malcolm is dead and his grudges along with him.
* May be small compared to the other examples in this trope, but it's discovered at the end of the ''Series/{{Awkward}}'' season 1 finale that the 'carefrontational' letter was written by Jenna's mom, Lacey.
* [[AlternateCharacterInterpretation Depending on who you ask]], this may be present in ''Series/{{Firefly}}'' in the form of River and Simon Tam's parents, whose callous disregard for River's plight at the [[SchoolForScheming Academy]] may have been due to foreknowledge of what the Academy was [[MindRape doing to her]].

* ''Series/{{Justified}}'': Arlo betrays Raylan several times.

* On ''Series/{{NCIS}}'', Ziva being kidnapped by hostile terrorists and nearly murdered multiple times can be linked back to her own father.

* ''Series/PrisonBreak'' has Christina Rose Scofield who ends up trying to kill both her sons.
* ''Series/TwentyFour'': [[spoiler:Jack's father]] was a Big Bad, the Man behind the Man ([[spoiler:Graem]]) behind the Man ([[spoiler:President Logan]]) behind the Man (attempted assassination of the Russian President). Attempted to kill his son. [[spoiler:And he did kill his other son Graem for failing him.]]
* Series/VeronicaMars has Aaron Echolls and to a much lesser extent Veronica's Mum who abandons Veronica twice and the second time she does it she takes Veronica's college fund for good measure.

[[folder:New Media]]
* [[spoiler:Sarah]]'s dad and [[spoiler:Bree]]'s mom in ''WebVideo/Lonelygirl15'' are both examples.

** The one that started it all: Lorgar was the first to view the Emperor as a god, and his Legion took longer than the others to reconquer planets because they kept building temples and proselytizing the natives. The Emperor showed up with Ultramarines in tow, made the Word Bearers watch as they tore down the temples, and finally kneel before them. Little wonder that Lorgar paid attention when he heard about [[GodOfEvil gods that rewarded faith and loyalty]], or that he'd end up converting Horus to his cause.

--> Your presence does not surprise me, Assassin. I have known of you ever since your craft entered the Eastern Fringes. Why did I not have you killed? Because your mission and the act you are about to commit proves the truth of all I have ever said or done. I merely punished those who had wronged, just as your false Emperor now seeks to punish me. Death is nothing compared to vindication.

* In ''VideoGame/{{Mass Effect|1}}'', Wrex eventually explains that he was a leader of his people back on his homeworld following the Krogan Rebellions. He was advocating peace so that the Krogan could rebuild, but his father, Jarrod, was a rival warlord pushing for war. Wrex and Jarrod agreed to meet on neutral ground to discuss their differences. Being [[ProudWarriorRaceGuy krogan]], though, it could only end [[BlastOut one way]]. Jarrod's troops managed to wipe out Wrex's followers, forcing him to leave the planet both for his own survival and because he was disgusted with his own species' self-destructive nature, but not before Wrex managed to kill his father for the betrayal.
* The ''Franchise/SilentHill'' series does this several times:
** In the original ''VideoGame/{{Silent Hill|1}}'', Dahlia Gillespie set her own daughter on fire, but magically kept her alive, to force the girl to use her magic powers for Dahlia's own sinister purposes. This is referenced in ''VideoGame/SilentHill3'' and ''VideoGame/SilentHillOrigins''.

* ''VideoGame/DiabloIII'' has [[spoiler:Adria]], in one of the cruelest betrayals of the entire series, [[spoiler:revealing herself to be Diablo's high priestess before using the Black Soulstone, with all seven Great Evils inside, on her own daughter Leah, who she had for the sole purpose of using her as the vessel for Diablo's rebirth as the Prime Evil.]]
* ''VideoGame/BlazBlue''. Carl Clover, a young boy who's innocent and cheery, was deeply traumatized when it turns out his father Relius nonchalantly turned his sister Ada into a Nox Nyctores, a mechanical doll known as Nirvana... and it was incomplete, and he just left the incomplete Nirvana for Carl to finish. This event caused Carl to become extremely bitter to both the world and adults in general. Making matters worse, the next time he met Relius, he found out that Relius did the same to Carl's mom, Relius' wife, Ignis, and ''still'' with the same nonchalant attitude of ForScience.

* ''VideoGame/TheLegendOfDragoon'' has Dart's father turn out the be the BigBad. [[spoiler:It turns out he was possessed by Melbu Frahma, but still.]]

* Gaia of Myth/GreekMythology did this to three generations' worth of her divine progeny after they pissed her off by empowering the next generation. Her first son Uranus [[ParentalIncest who was also her first consort]] was jealous and fearful of their children the Titans and trapped them inside Gaia. A pissed off Gaia forged a huge sickle and gave it to her youngest son Cronus and had him ''[[GroinAttack castrate]]'' Uranus with it.

Even after Sherry realizes how screwed up everything is (partly due to her mother agreeing with everyone else to punish her for no good reason) and decides to leave, her mom stays.

* Played straight and then inverted in ''Series/{{Angel}}'s'' final season episode "Lineage". Roger Wyndam-Pryce, Wesley's father. It turns out he intends to steal Angel's free will. Then it turns out he was a robot (which was shot by Wesley ''before'' the revelation).

* While on the extremely low end of this trope, ''Anime/{{Beyblade}}'' has Judy Tate, who sandbags her visiting son Max Mizuhara and his friends into being test subjects for the corporation she works at, mostly so they can obtain data to beat the Bladebreakers. Later in the series, she does aid them, and is not truly a big bad. Also, when her son's victory [[spoiler: causes a power surge that wipes out all her research]] she smiles and simply starts over, and wishes her boy well. But she sees no conflict in using her son this way, openly mocks his philosophy (while half-allowing for the possibility of it) until beaten, and chides his teammates for not seeing the deceptive methods she used as 'a friendly match', and the only ones who call her out are the other people at her corporation, who wonder if her loyalty to Max will affect their research.
