Not all parents are [[AdultsAreUseless useless]] or [[AbusiveParents evil]]. There are quite a few who actually [[GoodParents seem interested in their children's welfare]]. Sure, they might be [[MamaBear a little]] [[PapaWolf overprotective]] or annoying, but they mean well.

And then there are parents who take the noble principle of looking out for their kids, and go a bit overboard. Just as a KnightTemplar or a WellIntentionedExtremist commits all sorts of illegal or immoral deeds in the name of a cause, a Knight Templar Parent does equally questionable things to [[SafetyWorst ensure his or her child's safety]]. While a normally protective parent would have a VerySpecialEpisode about telling their kid not to buy illegal drugs, a Knight Templar Parent would track down and [[ThereIsNoKillLikeOverkill kill every drug dealer in town]]. Just to be sure.

When the kids grow up and flee the nest as fast as their battered sense of independence can carry them, this parent is demoted to [[MeddlingParents Meddling Parent]]. Though this may be difficult if it doubles up with MyBelovedSmother.

Compare MamaBear and PapaWolf, which is more or the same concept but only occurs as an immediate defensive reaction to an emergent threat, and does not necessarily entail vengeance or DisproportionateRetribution. The EvilMatriarch is often an extreme version of the Knight Templar Parent, though by no means always. See also MyBelovedSmother. An older brother who will protect/avenge his younger sibling by any means neccesary is a KnightTemplarBigBrother, which is an extreme version of BigBrotherInstinct. For Knight Templar Parents minus the KnightTemplar part, see GoodParents.

[[folder:Anime and Manga]]
* ''Manga/{{Berserk}}'': The King of Midland practically destroyed his own kingdom just to make Griffith's life a living hell after he [[spoiler: deflowered]] his precious daughter, Princess Charlotte [[spoiler: who he later tried to rape and evidently fell deeper and deeper into insanity afterward.]]
** The Count can also count, since he was so determined to keep his daughter Theresia away from the evils of the world [[spoiler: himself being one of them]] that he locked her in her room for most of her life.
* ''Anime/CodeGeass'' pulls this rather surprisingly with '''both''' of Lelouch's parents, Emperor Charles (whom he despised) and Empress Marianne (whom he revered); the two formed a plan to change the world for the better shortly after they met, and since Lelouch and his sister Nunnally were their favorites, they intended to let the kids in on it when they were old enough. However, they didn't bother taking into account how the kids would feel about forcibly changing the nature of all of humanity. And all this is before you throw in their EvilPlan to protect the kids which resulted in both kids being mentally and emotionally scarred, and drove Lelouch to try to kill his father in the first place.
** Lampshaded in the audio commentary for the episode in which the parents' Templar-hood is revealed, when the episode's director comments "They probably thought they were doing the right thing, but [[spoiler:Lelouch]] wanted to say that they weren't GoodParents. We wanted to make sure that was clear."
* A minor suspect in an early ''Manga/DetectiveConan'' story locked her own son Akio in the basement of her house for six years so the StatuteOfLimitations would run out on Akio's accidental murder of his apparently abusive father... even when Akio ''did'' aknowledge his guilt and wanted to pay for his crime, and being locked downstairs only made him cross the DespairEventHorizon. Ultimately, Conan and the Detective Boys found out as they sneaked in the apparently abandoned house; Conan uncovered the mother, helped Akio convince her to let him go, and they turned themselves in together.
* Suits Renton and Eureka to the T in ''Anime/EurekaSevenAo'' for their goal to ensure their son Ao's survival [[spoiler: after the tragedy that happened to their firstborn daughter.]]
* Maes Hughes from ''Manga/FullmetalAlchemist'' ''pulls a gun'' at a bunch of three-year-old boys who want to play with his daughter, who's of the same age. Excused by it being a CrowningMomentOfFunny.
* In ''Manga/KareKano'', [[spoiler: Reiji Arima]] is ''extremely'' protective of his [[spoiler: biological]] son Souichirou, so much so that [[spoiler: he is willing to ''kill'' Souichirou's mother [[AbusiveParents Ryouko]] for abusing him during his childhood ''and'' leaving him to die when he's been badly beaten up by her when he finally finds him]] and in fact, [[spoiler: is close to doing it]] until Souichirou intervenes.
* Despite typically being cold and dismissive toward his daughter Hinata, Hiashi Hyuga of ''Manga/{{Naruto}}'' has some hallmarks of this, like when he activated his brother's curse seal merely because he sensed that he was considering harming Hinata.
* Whitebeard of ''Franchise/OnePiece'' is an example of this to his "sons," as he considers killing a crewmate to be an unforgivable crime. When Ace, who had gone after Blackbeard for killing his division commander, lost to Blackbeard and was turned over to the World Government, Whitebeard sent his entire fleet of pirates to Marineford to save him, playing into the World Government's plans [[spoiler:as well as Blackbeard's]].
** This being [[BadAss Whitebeard]] however, he was playing a hefty case of XanatosSpeedChess with the World Government during the encounter and [[spoiler: his defeat and demise]] happened because of unforeseen events such as [[spoiler: Blackbeard turning up and Ace being killed, resulting in a HeroicBSOD]].
* [[MoralMyopia Kham's father]], the Santovasku Emperor from ''Manga/{{Outlanders}}'' (the manga moreso than the anime). Yeah, he may be just a bit [[IDidWhatIHadToDo extreme in his methods]]--[[spoiler:even going so far as to brainwash his own daughter, making her forget the "lowly Earth-born human" husband that he does not approve of and encouraging her to murder the boy; he also destroys the entire frikkin' Earth in his rage]]--he's really not ''[[EvilVirtues all bad]]''. After all, [[NecessarilyEvil he has the welfare an entire pan-galactic empire to look after]], and humans like his new son-in-law (who has basically rendered the Emperor's daughter [[spoiler:unmarriageable to another man) have basically been infesting, raping and despoiling the sacred Santovasku "Mother World"--yeah, they originated on Earth]]--since they first began to walk upright. [[WellIntentionedExtremist He's got plenty of reason to be a bit pissed-off, if you think about it]].
* [[spoiler:Giovanni]] from ''Manga/PokemonSpecial''. Wanna find your missing son? Simple, just [[spoiler: destroy the Sevii Islands, put other families through hell, nearly kill quite a few people, and put the protagonist through a whole lotta traumatizing shit, etc.]].
* Recent chapters of ''Manga/TsubasaReservoirChronicle'' suggest that [[spoiler:Syaoran and Sakura Li went path for their son, [male] Tsubasa. Their moves include getting sealed in separate parts of a glass container for the better part of their offspring's lives as a payment for his safety, Sakura sacrificing a MagicWand she was given by [[Manga/CardcaptorSakura an alternate universe version of herself]] so [male] Tsubasa can go to an alternate dimension to help [female] Tsubasa, [[OedipusComplex his love interest]], and then facing the BigBad in a battle that potentially can destroy the multiverse in an AWESOME BigDamnHeroes moment. All this because [male] Tsubasa fell in LoveAtFirstSight with the person his mother was cloned from.]]

[[folder:Comic Books]]
* The ''twelve'' members of the Pride in ''Comicbook/{{Runaways}}'' are promised ''six'' places in a coming paradise. In order to avert infighting about who gets the honor, each of the six couples agrees to grant a spot to their children. Of course, earning these six places involves routine human sacrifice and taking over the world....
** Don't forget how Geoffrey Wilder from the 1980s bargained with the Gibborim in the present - just because he wanted his to-be-deceased wife and son back (keep in mind that at this time, Geoffrey hasn't even ''met'' Alex yet. He also chooses Nico as the sacrifice just because she refused the advances of Alex. Oh, and there's also the time when the kids are stuck in 1800s New York and Chase meets the past versions of the Yorkes, who were also time traveling in that date. Upon learning from Chase that their daughter is going to die in the future, Mr. Yorkes tries to attack him. The pair immediately begin making plans to keep Gertrude safe - and bring a nuclear bomb from the future to blow up 1800s New York. As revenge for Getrude dying in ''any'' possible future.
* Mr.Chau from ''ComicBook/ScottPilgrim''. Once he finds out his daughter, Knives, is dating a 23-year old white boy (or used to at this point) he did the most logical thing possible... He went around with his ceremonial sword and hunted Scott so he could decapitate him. This eventually helped Scott though as he used Mr.Chau as a distraction in a battle with one of Ramona's evil exes and, after that, made peace with him.
[[/folder]]

[[folder:Fairy Tales]]
* Some adaptations of the FairyTale ''Literature/{{Rapunzel}}'' portray the witch this way, possibly to make her seem more sympathetic. Included among them are the Donna Jo Napoli's novel ''Zel'' and StephenSondheim's musical ''Theatre/IntoTheWoods''. In both those versions, the witch truly loved Rapunzel and was trying to protect her.
[[/folder]]

[[folder:Fan Works]]
* In ''FanFic/TheImmortalGame'', [[TheDragon Esteem]] claims that everything he did to Rarity -- TrainingFromHell, emotional (and possibly physical) abuse, killing her mother (who opposed his plans) -- was all for her own good, to make her strong enough to survive and rule by his side in the new order he'd help [[BigBad Titan]] create. [[note]] He also nearly cut out Prince Blueblood's tongue for how he treated her; he's a real piece of work.[[/note]] She calls him out on this during their confrontation, and disowns him.
* In the ''Manga/{{Naruto}}'' fanfic ''FanFic/AFathersWrath'', instead of the yondaime, Naruto's father is Orochimaru. He's so enraged by Naruto being made into a jinchuriki, that in this continuity it's his primary motive for forming the sound village and attempting to destroy Konoha. In sound, he also makes Tayuya something akin to a slave for Naruto [[DisproportionateRetribution for slapping him]]. It's implied he would have had her killed if Naruto hadn't spoken up about being in a panic at the time and that she'd been trying to calm him down. Otherwise, however, he seems to be a just ruler, and a devoted parent.
* [[MissingMom Padme]] from the ''Franchise/StarWars'' FanFic, ''[[http://fanfic.theforce.net/fanfic.asp?action=view&ID=804 By the Grace of Lady Vader]]'' is this for both Luke and Leia. She will do ''anything'' to get her family back and keep them safe, to the point of imprisoning one of her own children. Fact that she seems to be a bit [[IRejectYourReality delusional]] and has [[MyBelovedSmother problems accepting the idea that said child might be in love with someone she doesn’t approve of and make independent decisions]], doesn’t help at all. [[DisappearedDad Anakin]] also shows the same traits but his methods are different.
** Though to be fair: Padme was locked up in a Sith prison for at least a decade, which is not considered good for your sanity, while Anakin got set on fire, his limbs chopped off...well there is a difference between parents who are like that without an excuse, and those who suffered like that.
* In [[Fanfic/RainbowDoubleDashsLunaverse the Lunaverse]], the Luna Six eventually come to a realisation as tragic as it is horrifying: Corona isn't a megalomaniacal EvilOverlord who wants to TakeOverTheWorld ForTheEvulz, but rather a MamaBear of a PhysicalGod who wants to protect Equestria by any means necessary... even from itself.
[[/folder]]

[[folder:Film - Animated]]
* In ''WesternAnimation/HotelTransylvania'', Dracula is fiercely protective of his daughter Mavis due to his promise to his dead wife that he'll protect her no matter what. He tries to instill within her his fear and hatred of humanity and built a massive hotel for monsters as a safe haven for her. He even builds a fake human village with his zombie minions playing a human mob (complete with torches and pitchforks) so that his daughter loses her wanderlust.
[[/folder]]

[[folder:Film - Live Action]]
* In ''Film/EasterBunnyKillKill'', the killer who's been taking out Remington's low-life friends out to be [[spoiler: Nick's seemingly-oblivious mother, Mindy.]]
* In ''Film/LaPielQueHabito'' (''The Skin I Live In'') the father of a nearly-raped girl [[RoaringRampageOfRevenge goes out of his way]] to punish the perpetrator.
* Jack Byrnes (Robert de Niro's character) in ''Film/MeetTheParents''.
* ''The Positively True Adventures of the Texas Cheerleader-Murdering Mom'' is based on a true story about a woman who plotted to kill her daughter's cheerleading rival.
* Keller Dover from ''Film/{{Prisoners}}''. Over the course of the film, he went from being appropriately paranoid about his missing daughter and her friend, to outright kidnapping Alex Jones, just because he suspects that the man is responsible for their kidnapping.
* Anakin Skywalker of ''Franchise/StarWars''. Heartbroken by the seemingly impending death of his wife and possibly of his child (whose future he cannot see in his visions), he goes on a savage killing spree to to immerse himself in the powers of the Dark Side of the Force, in order to gain the power to save Padme Amidala and, if need be, the baby too. (Note that this is not precisely clear in the movies - the novelization makes it much more apparent.)
* Christof in ''Film/TheTrumanShow'' takes this to the extent of trapping his adoptive son Truman in an entire "[[StepfordSuburbia perfect]]" fake world, with actors playing every person in Truman's life, so that Truman will never be exposed to the evils of real life.
** At least this is what he claims. The fact that he then TELEVISES this as "the ultimate reality show" rather makes that doubtful as his real motive. He even instills a phobia of flying or sailing in Truman to keep him from finding out he's in a huge dome.
* Viktor in the ''Film/{{Underworld}}'' series, to the point where the entire Vampire-Lycan War began due to his being so much of one that he had his daughter, Sonja, executed after finding out she was pregnant with the child of a Lycan. Naturally, when several centuries later he discovered his [[ReplacementGoldfish adoptive daughter]], Selene, had begun to consort with a Lycan, ''he doesn't take it well.''
* Jacob in ''Film/OctoberBaby'' is perfectly fine with violating the Hippocratic oath, lying, and generally being a dick to his adopted daughter Hannah if it means keeping her under his thumb.
* Warren Worthington II in ''Film/XMenTheLastStand'', given that his son is a mutant.
[[/folder]]

[[folder:Literature]]
* Margaret White from ''Literature/{{Carrie}}'', who is also an EvilMatriarch.
* Played with in ''Literature/TheCountOfMonteCristo'': Madame de Villefort will go to any lengths to ensure that her son inherits a large fortune; [[spoiler: which includes poisoning nearly every member of her family, including her step-daughter]]
* ''Film/{{Dogtooth}}'' takes this trope and runs with it: both parents keep their kids in the confines of their estate, crafting images of the world outside as highly dangerous and suspicious. This leads to their portraying cats as "the most dangerous animal of all," for example.
* Both Charity and Michael in ''Literature/TheDresdenFiles'' can qualify. Especially after [[StormingTheCastle what Charity goes through to get Molly back.]]
** [[spoiler:Harry Dresden himself]] in ''Changes''. The Red Court took his daughter, and he will do ''whatever it takes'' to get her back. Including [[spoiler: becoming the Winter Knight and causing the genocide of the entire Red Court.]]
*** It goes beyond that. He mentions to [[spoiler: Mab]] that if she didn't take him up on his request, he'd be willing to take up Lasciel's coin and join the Denarians, an organization of fallen angel-possessed immortals whose goal is to literally cause as much suffering to humanity as a whole as possible. And if ''that'' failed, he'd summon a Darkhallow, murdering hundreds of thousands and becoming, basically, a god. All of this, just to ensure his daughter's safety.
** The Red Court screwed Harry over during a duel to the death, with the vampire in question trying to toss a dozen bruisers into the ring to kill Harry. Ebenezar [=McCoy=] didn't take that very well, and proceeded to [[spoiler: [[ColonyDrop drop a Soviet satellite on said vampire's home, wiping him out]].]]
* Literature/HarryPotter features a clever ''heroic'' inversion with Narcissa Malfoy. She is willing to betray her sworn master Lord Voldemort just to protect Draco, up to the point of [[spoiler:hiding the fact that Harry was not killed by Voldemort as he thought.]]
** It also includes a more traditional version with Molly Weasley: the otherwise soft hearted and kind mother kills [[spoiler: Bellatrix Lestrange]]. This counts as more than just MamaBear in part because it's the only recorded killing curse ever used by someone other than a bad guy in the books. Doubly surprising considering how strong and experienced her opponent was, but works as an in-universe version of the mythical mother lifting a car off her child. ''"Not my daughter you bitch!"''
* Lucretia, a Roman nobleman, was the [[ProperLady most virtuous woman in Rome]]. As a result [[FridgeLogic of this offense]] the Etruscan prince ruling Rome raped her. She went before her husband and father and [[HonorRelatedAbuse comitted suicide]]. In their rage they took a blood oath and then gathered all the good citizens of Rome to join them. Whereupon they decided to act [[ThisMeansWar as good Romans should.]]
* Adam Hauptman of the ''Literature/MercyThompson'' novels can be like this with his teenage daughter, Jesse. When Jesse is beat up at school because her father is a werewolf, she refuses to tell her father who it was, because if he knew, he would kill them.
* Sara in ''Literature/MySistersKeeper''. Sara had a child (Anna) ''specifically'' so it would be a perfect tissue match for her middle daughter Kate, who has severe leukemia. She also neglects her older son Jesse once it is found out he is not a genetic match for Kate. After Kate's kidneys fail, Sara and her husband want to use Anna's kidneys. Anna deciding, she's had enough [[spoiler: and sues them for medical emancipation. ''With Kate's blessing''.]]
* Queen Cersei Lannister in ''Literature/ASongOfIceAndFire''; she is terrified that something will happen to her children (not an unjustified fear, given [[spoiler: they're born of incest with her brother and are thus treason to her royal husband]]) and protecting them is a large part of her motivation in some of the most immoral acts in her regency. It's easily [[SmugSnake her most favorable attribute]].
[[/folder]]

[[folder:Live Action TV]]
* ''Series/{{Alias}}'':
** Jack Bristow. In the course of protecting his daughter, Jack has tortured and killed people, faked people's deaths, played multiple simultaneous games of GambitRoulette, [[spoiler: shot his own wife in the head when he'd thought she'd put a contract out on Sydney]], counter-brainwashed Sydney to resist programming, endured radiation poisoning, and eventually [[spoiler: sacrificed his own life]]. [[PapaWolf Never]], [[RoaringRampageOfRevenge ever]], find yourself so much as threatening his daughter. It will not end well.
** Irina reaches this status as well, for villainous reasons. She uses both her daughters as nothing more than pawns in her endgame, but [[MagnificentBitch god help you]] if you attempt to interfere with that plan.
* Mr. Bennet on ''Series/{{Heroes}}'' seems a little too eager to protect his daughter, despite her being [[NighInvulnerability almost physically invincible]]. [[spoiler:It later emerges that he's trying to protect her from being [[TheyWouldCutYouUp imprisoned and experimented on]] by his bosses, who ordered him to return her to them if she ever developed a superpower.]]
** Angela Petrelli. She even said at one point that her generation "mortgaged their souls" for the current heroes' generation. Her most obvious manifestation of this would be that she has tried to make her eldest son President by blowing up New York City.
* ''Series/{{Lost}}'': Ben is so worried Alex will get pregnant (which on the island is a death sentence) that he jails her boyfriend and then orders him brainwashed in a ''Clockwork Orange'' fashion. [[spoiler:Michael is also willing to pull a FaceHeelTurn to get him and Walt off the island.]]
* On ''Series/{{Misfits}}'', Nathan leers at a girl named Jessica and then is beaten to death by a mystery person (luckily he has ResurrectiveImmortality). They find that another guy who flirted with Jessica also died. Simon goes on a date with this girl and they try to warn him, assuming she's a BlackWidow. It's later revealed that [[spoiler: her father is the one killing all the boys that so much as look at her.]]
* Gibbs from ''Series/{{NCIS}}'' might not be a biological father of anyone on his team, but he plays the role of Team Dad often enough (and well enough) to generally count here. Heaven help you if you hurt one of his agents - especially Abby.
** A fact that Team Gibbs is ''fully'' aware of, as Abby proved in one episode when he asked why she hadn't told him about her crazy stalker ex:
-->'''Abby:''' Because, I wanted him restrained...not bludgeoned to death with a baseball bat.
** The episode "SWAK" revolves around the CEO of a biological research company and mother of a rape victim sending a letter containing a genetically mutated strain of pneumonic plague to NCIS (which Tony ends up inhaling). In the letter, she declares that she will only release an antidote for the strain if NCIS stop hiding the identity of the midshipman who raped her daughter. In the episode's final act, it is revealed that [[spoiler:the CEO has a terminal, inoperable brain tumour and is no longer acting rationally; the microbiologist who developed the strain of plague encoded a suicide gene which kicks in after 32 hours; and the CEO's daughter was not raped, but tied to a hotel bed as part of a sex game with a midshipman who, before untying her, stepped out for fast food and was killed in a hit and run accident.]]
* ''Series/OnceUponATime'': While Emma occasionally slides into this, Rumplestilskin is a definite, absolute example of this. He gains dark magic to save his son from [[ChildSoldier going to war]], and then afterwards repeatedly uses those powers [[DisproportionateRetribution unnecessarily]] when anything remotely bad ever happens to the boy afterwards.
** In season two, [[spoiler: Belle's father]] becomes this when he tries to [[spoiler: forcibly remove all of her memories of the Enchanted Forest just because he wants to get her away from [[DatingWhatDaddyHates Gold]]]]. He has good reason not to approve, but his methods aren't exactly reasonable.
* Yoo Won Gook in ''Series/VampireProsecutor'' kills any one who so much as ''hints'' at [[BerserkButton harming his daughter]], Jung In. The fact that she's a prosecutor working hard to arrest him complicates matters. To this end, he even distances himself from her so that she won't be implicated when he is indicted.
--> '''Jung In''': He's the bad guy. He's someone I have to lock away. But when the reason he did those bad things is because of me, I can't call him the bad guy. I can't even hate him.
[[/folder]]

[[folder:Music]]
* {{Eminem}} took this trope to ridiculous extremes at the end of his otherwise CrowningMomentOfHeartwarming song "Mockingbird". It's all PlayedForLaughs, though.
* Music/{{Mothy}} gives us Gallerian Marlon, who is practically the embodiment of this trope. [[http://www.youtube.com/watch?v=d2SXc0dH4K8 Seriously, just watch.]]
[[/folder]]

[[folder:Video Games]]
* In ''VideoGame/{{Borderlands 2}}'', [[spoiler: Handsome Jack]] himself. Late in the game, [[spoiler: Angel]] is begging you to kill her, and he is screaming at her to stop, saying that all the bandits he's killed and people he's manipulated and the world of pure order he's trying to establish is ''to protect her.'' Keep in mind that by this point, [[spoiler: Angel]] has spent most of her life imprisoned [[spoiler: due to her Siren powers]] and used as a biological computer by her father, and [[spoiler: has spent the last five years being used as a living catalyst to charge the Vault Key with Eridium]], so her father's pleas sound hollow to everyone but himself and his extremely twisted viewpoint.
* Queen Dowager Almedha from VideoGame/FireEmblemTellius is so determined to save her son Pelleas's life, that she's willing to let the kingdom of Daein be destroyed if that's the key to [[spoiler: undo Pelleas's DealWithTheDevil.]] More ironic if we see that [[spoiler: Pelleas is ''not'' her child. ''Soren'' is.]]
* Raphael from the ''VideoGame/SoulSeries'' has repeatedly tried to claim an incredibly evil sword on behalf of his adopted daughter, Amy. One time, it was to try give it to a country he hated so it's leaders would kill each other because of it. The other was so he could destroy an artifact that was curing people of the vampirism he was infecting them with so she wouldn't feel left out, having contracted vampirism from him as a result of his last attempt to get the sword. As Amy is an [[EmotionlessGirl Emotionless]] ElegantGothicLolita we have no idea how she feels about his insane plots.
** Apparently she just doesn't take him seriously at all, given that [[spoiler:in her ending sequence of ''VideoGame/SoulCalibur 4'''s story mode after Raphael claims Soul Calibur to create a new world for her... she pushes him into a pit during the requisite EvilLaugh.]]
*** With the obligatory "RING OUT" announcement as well.
[[/folder]]

[[folder:Web Comics]]
* ''Webcomic/TheOrderOfTheStick'' pulls this one off in spectacular fashion: in comic [[http://www.giantitp.com/comics/oots0639.html #639]], after dealing with an Ancient Black Dragon who showed up to avenge her son [[DisproportionateRetribution in a brutal fashion]], [[spoiler:Vaarsuvius uses the spell Familicide on her, which kills not only her family, but the family members of her other family members, and so on ''ad infinitum''.]] The page quote comes from the follow-up comic (and, it's worth pointing out, is directed towards the victim's severed head, ''reanimated solely for the purpose of delivering this monologue''). [[spoiler:V estimates that s/he killed a whole quarter of the black dragon population in the [=OotS=] universe.]] However, Karma lines up to give the perpetrator a kicking. [[spoiler:The power required to do it was acquired via a DealWithTheDevil, so V's soul is pledged to three separate Fiends]], and it's further revealed that included among the bloodline was [[spoiler: the family of Girard Draketooth, one of the legendary heroes who guards the gates imprisoning the Snarl.]] Perhaps most notably concerning this trope, though, [[spoiler:V's mate is so appalled at what s/he did that they file for divorce.]]
** This goes on with Elan's father Tarquin. He has some very specific ideas on what his son should aspire to and when Elan is content with what he has [[spoiler: Tarquin assumes that Elan's natural talents are held back by the rest of his group, so he tries to murder them.]]
[[/folder]]

[[folder:Western Animation]]
* In the episode "Over The Edge" in ''WesternAnimation/BatmanTheAnimatedSeries'', Jim Gordon of all people loses it when [[spoiler: [[AllJustADream Batgirl is killed]]]] and goes on a rampage to hunt down Batman (who he blames) in vengeance. He is even willing to release [[spoiler: Bane]] if it will help him capture Batman. [[spoiler: Fortunately, it was AllJustADream experienced by Batgirl herself, a result of the Scarecrow's fear gas; apparently, this sort of scenario was something she had dreaded happening ever since she became Batgirl.]]
* While not strictly their ''father'', Charles Offdensen of ''WesternAnimation/{{Metalocalypse}}'' is definitely the closest thing most of the band has to one, even if they don't realize it and generally misinterpret his presence in the Dethklok organization at all. He's also personally responsible for the utter ruin of everything that threatens the band in any way; the show's main antagonists are the threats he hasn't been able to ''find'' yet.
* Parodied quite a few times on ''WesternAnimation/SouthPark''. To give just a few examples, in "Child Abduction Is Not Funny", after misinterpreting statistics that show most children are abducted by their parents, the parents of South Park end up banishing the kids from town to protect them from being abducted. In "My Future Self and Me", they pay actors to pretend to be washed-up loser versions of their kids from the future in order to scare them straight. And let's not forget the many things Kyle's mom Sheila has done to "protect" the children of South Park, like the war with Canada and the public execution of Terrance and Phillip in ''WesternAnimation/SouthParkBiggerLongerAndUncut''.
* Considering the fact that Goliath from ''WesternAnimation/{{Gargoyles}}'' comes from a ProudWarriorRace, you would EXPECT this of him regarding Angela, but the unique "not knowing your parents" communal-raising style of the Clans has him tempered somewhat. At least when he's not being empowered/corrupted by the Eye of Odin and ends up doing some.. Questionable things to "protect" her and Elisa. Then there was the time the Quarrymen almost killed her; [[RoaringRampageOfRevenge it wasn't pretty]].
* Pre Flanderization WesternAnimation/FamilyGuy had [[MamaBear Lois]] and [[PapaWolf Peter Griffin]] were kind of like this during the series' early days. During the early parts of the series, they could react violently to an idea of anything happening to their kids. For example, Peter (in his usual idiot self), assaulted his daughter's purse when she said she hated him, and Lois had [[LovableSexManiac Quagmire]] visit the bully who humliated Meg in another episode. That shows how far they have fallen since the Flanderization [[AbusiveParents occured]]...
[[/folder]]

[[folder:Real Life]]
* [[http://www.capalert.com/ Tom Carder, the CAP Alert man]] is an excellent (real-life) example of this trope, if you're to believe that he searched his kids' electric sockets to try to find satanic symbols.
* Real life example: Christophe Fauviau, who doped the drinks of at least 27 tennis players due to face his son and daughter. After one match, one of these opponents passed out at the wheel of his car due to the medication he had been slipped. [[http://news.bbc.co.uk/1/hi/world/europe/4789066.stm He was killed in the ensuing accident.]]
* A [[OverprotectiveDad protective father]] [[http://www.telegraph.co.uk/news/worldnews/europe/germany/8197617/German-man-castrates-teenage-daughters-57-year-old-boyfriend.html Helmut Seifert takes the law into his own hands]] when he hears his daughter is sleeping with an older man. And decides to personally castrate him while he was conscious to experience the whole thing. Yes, being upset was perfectly warranted. However, when it gets to BodyHorror, it crosses into Knight Templar Parent territory.
