Knight Templar Parent

""If you let my daughter go now, that'll be the end of it. I will not look for you, I will not pursue you. But if you don't, I will look for you, I will find you, and I will kill you.""

- Bryan Mills, Taken

""Every living creature that directly shares your bloodline is dead. Every living creature that is directly related to any of those creatures is also dead...Now, no one will come to avenge your defeat. No one will lament your passing. Think about the fate you have brought upon your family as you suffer in the afterlife. This - and no less - is the price of threatening my family."

-, Order of the Stick

Not all parents are useless or evil. There are quite a few who actually seem interested in their children's welfare. Sure, they might be a little 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 Knight Templar or a Well-Intentioned Extremist commits all sorts of illegal or immoral deeds in the name of a cause, a Knight Templar Parent does equally questionable things to ensure his or her child's safety. While a normally protective parent would have a Very Special Episode about telling their kid not to buy illegal drugs, a Knight Templar Parent would track down and 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 Meddling Parent. Though this may be difficult if it doubles up with My Beloved Smother.

The Evil Matriarch is often an extreme version of the Knight Templar Parent, though by no means always. See also My Beloved Smother. An older brother who will protect/avenge his younger sibling by any means neccesary is a Knight Templar Big Brother, which is an extreme version of Big Brother Instinct. For Knight Templar Parents minus the Knight Templar, see Good Parents.

Anime and Manga

 * Kham's father, the Santovasku Emperor from Outlanders (the manga moreso than the anime). Yeah, he may be just a bit extreme in his methods--—he's really not all bad. After all, 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 —since they first began to walk upright. He's got plenty of reason to be a bit pissed-off, if you think about it.
 * Code Geass 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 Evil Plan to protect the kids which resulted in Nunnally being physically disabled and both kids being mentally and emotionally scarred.
 * 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 wanted to say that they weren't Good Parents. We wanted to make sure that was clear."
 * Recent chapters of Tsubasa Reservoir Chronicle suggest that
 * A minor suspect in an early Detective Conan story locked her own son Akio in the basement of her house for six years so the Statute of Limitations 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 Despair Event Horizon. 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.
 * from Pokémon Special. Wanna find your missing son? Simple, just.
 * Whitebeard of One Piece 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.
 * This being Whitebeard however, he was playing a hefty case of Xanatos Speed Chess with the World Government during the encounter and  happened because of unforeseen events such as.
 * Despite typically being cold and dismissive toward his daughter Hinata, Hiashi Hyuga of 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.
 * Maes Hughes 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 Crowning Moment of Funny.
 * Berserk: The King of Midland practically destroyed his own kingdom just to make Griffith's life a living hell after he  his precious daughter, Princess Charlotte
 * The Count can also count, since he was so determined to keep his daughter Theresia away from the evils of the world  that he locked her in her room for most of her life.

Comic Books

 * The twelve members of the Pride in 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 Scott Pilgrim. 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.

Fairy Tales

 * Some adaptations of the Fairy Tale "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 Stephen Sondheim's musical Into the Woods. In both those versions, the witch truly loved Rapunzel and was trying to protect her.

Fan Works

 * Padme from the Star Wars Fanfic, 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. The fact that she seems to be a bit delusional and has 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. Anakin also shows the same traits but his methods are different.
 * In the Naruto fanfic A Father's Wrath, 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 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.

Film

 * Jack Byrnes (Robert de Niro's character) in Meet the Parents.
 * Christof in The Truman Show takes this to the extent of trapping his adoptive son Truman in an entire "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.
 * The Positively True Adventures of the Texas Cheerleader-Murdering Mom is based on a true story about a woman who killed her daughter's cheerleading rival.
 * Anakin Skywalker of Star Wars. 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.)
 * Viktor in the 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 adoptive daughter, Selene, had begun to consort with a Lycan, he doesn't take it well.

Literature

 * Adam Hauptman of the Mercy Thompson 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.
 * Queen Cersei Lannister in A Song of Ice and Fire; she is terrified that something will happen to her children (not an unjustified fear, given ) and protecting them is a large part of her motivation in some of the most immoral acts in her regency. It's easily her most favorable attribute.
 * Played with in The Count of Monte Cristo: Madame de Villefort will go to any lengths to ensure that her son inherits a large fortune;
 * Sara in My Sister's Keeper. 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
 * Both Charity and Michael in The Dresden Files can qualify. Especially after what Charity goes through to get Molly back.
 * . The Red Court took his daughter, and he will do whatever it takes to get her back. Including
 * It goes beyond that. He mentions to  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
 * Harry Potter 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
 * It also includes a more traditional version with Molly Weasley: the otherwise soft hearted and kind mother kills . This counts as more than just Mama Bear 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!"

Live Action TV
"Abby: Because, I wanted him restrained...not bludgeoned to death with a baseball bat."
 * Mr. Bennet on Heroes seems a little too eager to protect his daughter, despite her being almost physically invincible.
 * 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.
 * Two words: Jack Bristow.
 * To elaborate, in the course of protecting his daughter, Jack has tortured and killed people, faked people's deaths, played multiple simultaneous games of Gambit Roulette,, counter-brainwashed Sydney to resist programming, endured radiation poisoning, and eventually  . Never, 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 god help you if you attempt to interfere with that plan.
 * 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.
 * Gibbs from 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:

"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."
 * Yoo Won Gook in Vampire Prosecutor kills any one who so much as hint at 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.

Music

 * Eminem took this trope to ridiculous extremes at the end of his otherwise Crowning Moment of Heartwarming song "Mockingbird". It's all Played for Laughs, though.

Video Games

 * Raphael from the Soul Series 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 Emotionless Elegant Gothic Lolita we have no idea how she feels about his insane plots.
 * Apparently she just doesn't take him seriously at all, given that
 * With the obligatory "RING OUT" announcement as well.
 * Queen Dowager Almedha from Fire Emblem Tellius 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  More ironic if we see that

Webcomics

 * Order of the Stick pulls this one off in spectacular fashion: in comic #639, after dealing with an Ancient Black Dragon who showed up to avenge her son in a brutal fashion, The page quote comes from the follow-up comic. It is later revealed that  And included in that was

Western Animation

 * Parodied quite a few times on South Park. 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 South Park: Bigger, Longer, and Uncut.
 * While not strictly their father, Charles Offdensen of 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.
 * In the episode "Over The Edge" in Batman: The Animated Series, Jim Gordon of all people loses it when  and goes on a rampage to hunt down Batman (who he blames) in vengeance. He is even willing to release   if it will help him capture Batman.

Real Life

 * 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. He was killed in the ensuing accident.
 * A protective father 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 Body Horror, it crosses into Knight Templar Parent territory.
 * Emperor Francis Josef of Austria was a knight templar uncle. He started World War I when his nephew was assassinated.
