* ''ComicBook/SheHulk'': [[Characters/SheHulkTitleCharacter She-Hulk]] and the [[Characters/MarvelComicsBruceBanner Hulk]] are cousins, but they have a Brother/Sister relationship. She-Hulk can take care of herself most of the time, but pity the poor fool who harms She-Hulk within proximity of The Hulk. She-Hulk herself can be extremely overprotective of The Hulk as well. ComicBook/IronMan got his ass handed to him by She-Hulk when she found out Stark [[ComicBook/PlanetHulk exiled Hulk into space]].

* Elro in ''VideoGame/{{Iconoclasts}}'' was already protective of Robin from the start due to the passing of their father, but he takes it too far after [[spoiler:his wife and daughter are killed]] and Robin decides to keep fighting One Concern against his wishes. His aggressiveness and refusal to do anything that would put Robin in danger (even though any idiot can see that Robin is clearly capable of handling herself) makes him the TheMillstone of the party, resulting in him trying to take on TheDragon alone by locking himself in with her (this gets [[spoiler:his arm ripped off]] and scatters the party across the world) and being very uncooperative in a plan that's vital to ''saving the planet''. [[spoiler:The cruel irony is that, while he never admits it, Elro is the initial ''cause'' of all the dangers Robin goes through; before the game started, he performed a petty act of rebellion against One Concern (whom he blamed for his father's death), which killed Agent Grey, which caused Agent Black (the aforementioned Dragon) to become bent on getting revenge on Elro and his family, as Grey was the one person who treated Black with genuine kindness and it's strongly implied she was in love with Grey because of this]]. At the very end of the game, he grudgingly admits that he could probably stand to ease up a bit on his overprotectiveness. Robin had to [[spoiler:single-handedly kill the being worshipped as an all-powerful creator god by One Concern]] for this to happen. [[spoiler:Granted, this "god" was really just some alien trucker's spaceship, but Elro doesn't know that]].

* In the original manga of ''Manga/DeathNote'' Light Yagami claims in an early MotiveRant that part of the reason he's killing criminals ''en masse'' is to make the world a safer place for his little sister Sayu. It might even be somewhat true. [[spoiler:Sayu is, after all, the only person he refused to kill when it would be to his advantage to kill her. Then again, it could be that he just realized Mello would keep kidnapping people until he finally did something about it other than kill their prisoners.]]

* Lelouch Lamperouge from ''Anime/CodeGeass''.

* [[Characters/GravityFallsDipperPines Dipper Pines]] from ''WesternAnimation/GravityFalls'' can be this. Though he and his sister Mabel are twins (and he's the younger one), [[BewareTheNiceOnes he is perfectly willing to exact some revenge on those who wronged her]]... even if she doesn't want revenge herself.

* [[spoiler: James Vane]] from ''Literature/ThePictureOfDorianGray''. His little sister [[spoiler: Sybill]] killed herself when he was working abroad, so when he found out, he swore to kill the culprit, Dorian Gray. [[spoiler: He ''almost'' got his wish, but was accidentally shot to death.]]

* Corsicans in ''ComicBook/{{Asterix}}''. This is what happens when a Corsican asks you if you like his sister. If you say you don't like her, he'll feel you've insulted her. If you say you like her, he'll kill you for daring to flirt with her.
* In ''Franchise/TheDCU'', [[Franchise/{{Superman}} Kal]] and [[ComicBook/{{Supergirl}} Kara]] are cousins but have a sibling-like relationship which is even closer than usual due to being the last ones of their kind. Hurt her and Superman ''will'' [[ComicBook/TheSupergirlFromKrypton2004 pummel you and pin you to the physical limit of the universe]], even if you are a [[ComicBook/{{Darkseid}} god of Evil]]. Hurt him and Supergirl ''will'' beat you to death, even if [[ComicBook/CrisisOnInfiniteEarths you are a multiverse-eater]].
* Beryl from ''ComicBook/DestroyerDuck'', who is prone to get rough to protect her younger sister Opal from anyone.
* Lynne to Marcie in ''ComicBook/{{Finder}}''. He wouldn't give his older sister Rachel the time of day, though because he figured out she's only his half-sibling and isn't actually a halfbreed like him and Marcie.
* ''ComicBook/SheHulk'': She-Hulk and the [[ComicBook/TheIncredibleHulk Hulk]] are cousins, but they have a Brother/Sister relationship. She-Hulk can take care of herself most of the time, but pity the poor fool who harms She-Hulk within proximity of The Hulk. She-Hulk herself can be extremely overprotective of The Hulk as well. ComicBook/IronMan got his ass handed to him by She-Hulk when she found out Stark [[ComicBook/PlanetHulk exiled Hulk into space]].
* How about that time ComicBook/{{Nightwing}} freakin' ''killed'' ComicBook/TheJoker with his ''bare hands'' when he thought he killed ComicBook/{{Robin|1993}}? Ol' {{Franchise/Bat|man}}s quickly revived him afterwards, but even still.
* ''ComicBook/TheMightyThor'': Thor's brother Loki is a manipulative, deceitful god of lies and mischief, and he often does bad things and sometimes gets punished for them... but if you dare hurt him unjustly Thor will smite you from the face of the Earth.
* ComicBook/{{Quicksilver}} for the ComicBook/ScarletWitch, except that he is her twin, not big brother. But [[RealityWarper recent portraying of Wanda's power]] suggest that if you attack Wanda, you are lucky if Quicksilver kicks your ass before ''she'' has to use her power.

* In ''ComicBook/UncannyXMen'', ComicBook/{{Colossus}} is this toward his sister ComicBook/{{Magik}}, to the point where he allowed himself to be possessed by the demon Cytorrak and became the new Juggernaut to protect her, losing his humanity and the love of Kitty Pryde in the bargain. Subverted in ''ComicBook/AvengersVsXMen'' when Illyana reveals she had manipulated him into becoming the new Juggernaut to make him see that she wasn't his sweet little sister anymore but a monster he shouldn't care for. Right off the bat Colossus vows that he would kill Illyana if they ever met again, but later they make up.

If you are the latter, then congratulations! You are officially a Knight Templar Big Brother (or Knight Templar Big Sister).

* [[Characters/SouthParkKennyMcCormick Kenny McCormick]] from ''WesternAnimation/SouthPark'' displays this in the episode "The Poor Kid". If you have the gall to mess with Karen [=McCormick=], Kenny proves that he WouldHitAGirl [[NoHoldsBarredBeatDown quite viciously]], as Jessica Pinkerton finds out. The rest of the school gets the hint that the girl is off-limits.

* ''Manga/JujutsuKaisen'': After Yuji and Nobara kill the [[HalfHumanHybrid Death Paintings]], Eso and Kechizu, their older brother Choso swears to kill them in retribution, and engages Yuji in a duel during the Shibuya Incident. [[spoiler:Though Choso emerges the victor after a difficult fight and has Yuji at his mercy, he can't bring himself to kill him after memories of himself, his brothers and Yuji sharing a meal together flood his mind, which causes Choso to walk away in abject confusion as he sweats buckets. This turns out to be {{foreshadowing}} to the fact that both Yuji and the Death Paintings are the children of [[GreaterScopeVillain Kenjaku]], [[BodySurf who once took for himself the body of Noritoshi Kamo]] and created the Death Paintings, which turned him into the BlackSheep of the Kamo Clan for centuries to come. Then, in modern times, Kenjaku [[ExtraParentConception took the body of Yuji's mother and gave birth to him]] as part of his plan to [[DesignerBabies create a vessel]] for [[TheDreaded Ryomen Sukuna]], effectively making Yuji and the Death Paintings siblings. When Choso figures out the truth, he is ''[[ThisIsUnforgivable furious]]'' that Kenjaku essentially sent his siblings to their deaths and tricked him into almost killing his brother, and becomes as fiercely protective of Yuji as he was with the rest of the Death Paintings (even addressing him as "little brother").]]

* ''Manga/JujutsuKaisen'': After Yuji and Nobara kill the [[HalfHumanHybrid Death Paintings]], Eso and Kechizu, their older brother Choso swears to kill them in retribution, and engages Yuji in a duel during the Shibuya Incident. [[spoiler:Though Choso emerges the victor after a difficult fight and has Yuji at his mercy, he can't bring himself to kill him after memories of himself, his brothers and Yuji sharing a meal together flood his mind, {{foreshadowing}} that they are both children of "Noritoshi Kamo" (which technically makes them siblings).]]

* Glenn Quagmire from ''WesternAnimation/FamilyGuy'' is a horrible man, but when he finds out that his (presumed younger) sister's boyfriend is abusive towards her, he ends up running over said boyfriend, killing him.
* Dipper Pines from ''WesternAnimation/GravityFalls'' can be this. Though he and his sister Mabel are twins (and he's the younger one), [[BewareTheNiceOnes he is perfectly willing to exact some revenge on those who wronged her]]... even if she doesn't want revenge herself.

* ''WesternAnimation/RickAndMorty'' sees the titular Morty gradually become this as he becomes a darker, more jaded character thanks to Rick's influence, though Morty is the younger brother. The best example is in "The Whirly-Dirly Conspiracy"; Summer develops issues with her self-esteem and body image after her boyfriend breaks up with her, and tries to change her body using an invention of Rick's, which goes horribly wrong and which Morty and Beth have to fix. Afterwards, Morty uses this same invention to horrifically disfigure Summer's now-ex-boyfriend as revenge for breaking her heart.
* Kenny [=McCormick=] from ''WesternAnimation/SouthPark'' displays this in the episode "The Poor Kid". If you have the gall to mess with Karen [=McCormick=], Kenny proves that he WouldHitAGirl [[NoHoldsBarredBeatDown quite viciously]], as Jessica Pinkerton finds out. The rest of the school gets the hint that the girl is off-limits.

** Absalom from ''Literature/TheBible'', who learns that his sister Tamar was raped and humiliated by their half-brother Amnon and, instead of going to their father David to demand he step up and administer punishment, he goes and kills Amnon himself. David was already well aware of what had occurred (2 Samuel: 22-23). His response was to be 'greatly upset'... and do absolutely nothing. Absalom decided to take justice into his own hands - it was obvious none was forthcoming from their father, the king.
** In a similar incident, two of the sons of Jacob killed everybody in a village for mistreating their sister. Presumably they wished the feud to [[LeaveNoSurvivors end right away]]. To put it into perspective, Jacob's daughter Dinah had been raped by a prominent member of the village who fell in love with her. Despite the circumstances, he and his father wanted to smooth over relations with Jacob's family and offered to pay for her dowry as if she'd still been a virgin, [[ValuesDissonance which was actually quite a generous offer at the time]]. Jacob seemed to warm up to the offer, but his sons demanded that all the men of the village circumcise themselves to become part of Jacob's tribe. The men agreed, with the idea that they would now be able to intermarry with Jacob's tribe. After all the men were circumcised and helpless, though, Dinah's brothers Simeon and Levi took advantage of the situation and slaughter the entire village, taking only women and children alive as slaves. When Jacob [[WhatTheHellHero criticized them for the actions]], saying that no one would trust him now, they only replied: [[MyGirlIsNotASlut "Our sister should not be treated like a whore."]] Jacob went along with this right up until just before he died, at which point he called them in and disinherited them for wiping out a village for the actions of one man.

* ''ComicBook/TeenageMutantNinjaTurtlesMirage'': Raphael, while not being the most [[SociopathicHero even-tempered]] character, is psychotically protective of little brother Michelangelo -- to the point where he states that the "thought of Mikey being hurt makes him experience violent rage" (see [[Website/{{Wikipedia}} The Other Wiki]]). And considering how violent Raphael is usually...

* How about that time ComicBook/{{Nightwing}} freakin' ''killed'' ComicBook/TheJoker with his ''bare hands'' when he thought he killed [[ComicBook/RobinSeries Robin]]? Ol' {{Franchise/Bat|man}}s quickly revived him afterwards, but even still.

--> '''Ryuk:''' And so you think by wiping out crime, you’ll save them. Daddy and your big brother will be free from their obligations and you’ll be a nice happy family again. But how many people are you willing to kill to make that happen, kid?
