* ''Webcomic/AxisPowersHetalia'' fanfic ''[[https://www.fanfiction.net/s/11886910/1/Gankona-Unnachgiebig-Unità Gankona, Unnachgiebig, Unità]]'': Hungary is one. The ''only'' reason she hasn't beat the ever-loving crap out of [[AbusiveParents Austria]] is because Italy begged her ''not'' to. However, even his begging was not enough to stop her from chasing after Prussia.
* ''[[http://hetalia-kink.livejournal.com/13125.html?thread=33502533#t33502533 The Howl of the Wind]]'': the spirit of the personification of Native America returns to torment the various nations for raping America.

[[AC:''Anime/KillLaKill'']]
* ''Webcomic/KillLaKillAU'': Ragyou will do anything to protect her children, even if it almost costs her life, like she did in comic 25. This version of Ragyou is a far cry from her [[EvilMatriarch horrendously]] [[ParentalIncest creepy]] canon counterpart.
* ''Fanfic/KiryuuinChronicles'': While she isn't their mother but a ParentalSubstitute, Rei is a downplayed example in that while she isn't powerful and was described to be "a kind, yet very frightened soul", she has made it her resolve to take her charges Satsuki, Ryuuko, and Nui away from their abusive home and father, regardless of circumstances.

[[AC:''Manga/LoveHina'']]
* ''Fanfic/ContractLabor'': Though not exactly Keitaro's mother, Haruka fits the bill in chapter 6; when Naru tries to attack Keitaro after an AccidentalPervert moment, Haruka physically restrains her, threatens her with a pocketknife, and explicitly threatens to use said knife on Naru if she doesn't back off.
* In ''[[https://www.fanfiction.net/s/5012739/1/Reunion Reunion]]'', Haruka's response to learning that the woman who molested Keitaro when he was only ten years old is to start carrying a handgun. When said woman actually manages to break in and rape him, Haruka confronts her at gunpoint and threatens to kill her if she ever sees her again.

[[AC:''Franchise/LyricalNanoha'']]
* ''Fanfic/{{Infinity}}'': In chapter 25, Lindy utterly humiliates [[PersonOfMassDestruction Precia]] in a one-on-one fight despite a vast difference in power between them, all because Precia hurt her children.
-->'''Arf:''' [[BewareTheNiceOnes Remind me to]] '''[[BewareTheNiceOnes never]]''' [[BewareTheNiceOnes tick off your mom again]].

[[AC:''Manga/MagiLabyrinthOfMagic'']]
* [[https://www.fanfiction.net/s/11057142/1/The-Brothers-Day-and-Night The Brothers Day and Night]], Mariam and Kassim's mother Lail was this. She tried to kill her children's abusive father to protect them, but ends up being overpowered and killed by him instead.

[[AC:''Manga/MyHeroAcademia'']]
* ''[[https://www.fanfiction.net/s/12520482/1/Fire-and-Blood-a-My-Hero-Academia-Story Fire and Blood]]'': Inko Midoriya is a massive one to her son Izuku and her [[ParentalSubstitute "may-as-well-be" son Shouto]]. Despite her lack of combat experience or a powerful Quirk, she is entirely willing to throw down with (meaning "attack with a rock") [[spoiler:the second-best pro hero on Earth]] to protect them.
-->'''Inko''' (to [[spoiler:Endeavor]]): You. Will. ''Not''. [[PunctuatedForEmphasis Hurt. My. Son.]]
** [[spoiler:Endeavor]] then threatens to make her pay, leading to Izuku flipping the script.
--->'''Izuku:''' ''[[PunctuatedPounding YOU THINK]]'' *punch* ''[[MamasBoy YOU CAN THREATEN]]'' *punch* ''[[ShoutOut MY MOTHER?!]]''
* ''Fanfic/SoonIShallBeIndestructible'' had the villain Overhaul get frozen to death by Rei Todoroki after he attacked her son Shoto.
* In ''Fanfic/LavandulaSomnambulist'', Midnight has been known to use her hero agency to ensure Izuku's safety and growth, using her interns "the Midnight Boys" to help him train his quirk and would have used them to turn the city inside out when his encounter with the Sludge Villain made him run late if Izuku hadn't made it home.
* In ''Fanfic/{{Viridescent}}'', after Izuku rescued Eri from the Eight Precepts, she's been living with the Midoriya family. When Overhaul and his men come to take Eri back, Inko responds by using her quirk to nearly tear his eyeball out with her telekinesis.

[[AC:''Franchise/{{Naruto}}'']]
* ''Fanfic/KitsuneNoKenFistOfTheFox'':
** Inuzuka Tsume, Konoha Town's police chief in this universe, is this for her son Kiba. Her first response to news that Kiba may be in trouble is to send dozens of cops to the location to arrest whoever's responsible. There's also her threat to Naruto following his confrontation with Kiba (for which Tsume had sent out the aforementioned cop-squad):
---> '''Tsume:''' If my son ever got so much as a scrape on him from you, I don't care if you were part of a group that terrified whole cities, I would stuff a shotgun up your ass and pull the trigger. Am I understood?\\
'''Naruto:''' ''(meekly)'' Yes, ma'am.
** Kushina is this for Naruto as well. After she finds him grievously injured [[spoiler:following a torture-session at Akatsuki's hands]], she goes through a HeroicBSOD...then goes to the home of one of the persons responsible and physically torments ''him'' into agreeing to surrender himself to the police.
* ''Fanfic/SonOfTheSannin'':
** Tsunade becomes this towards Naruto. To put it on perspective, when [[spoiler: Obito Uchiha]] declares his intent to kidnap her adoptive son, she [[MetronomicManMashing grabs him by the foot and slams him all over the place]]. [[spoiler:And then there's when Danzo tried to have her biological son Hagane kidnapped. Needless to say, the Root agents set to capture him didn't live very long.]]
** Hinata's mother Hikari Hyuga is no slouch either. [[spoiler:Even moreso after her husband gets killed.]]
** Shizune acts this way to her two children. [[spoiler:When Danzo tries to have both of them kidnapped, [[BattleCouple she teams up with her husband Shisui to kill him]].]] Afterwards, she demands from the Hokage that her children be babysat by ninja of Special Jonin rank or above instead of Genin (and only by those she personally trusts if possible).
** Tsume's own children are never directly put in danger during the course of the story outside of their own missions, but after [[spoiler:the aforementioned kidnapping of Shizune and Shisui's children]] she admits to wanting to hack the one responsible to death and feeding their remains to her dogs (though the last part was a joke, she'd never feed her dogs something so disgusting).

[[AC:''Anime/NeonGenesisEvangelion'']]
* ''Fanfic/ACrownOfStars'':
** [[TheHighQueen Rayana]] is the [[PhysicalGod patron deity]] of the Mamas Bear in [[TheMultiverse her home dimension]] (one of her titles is Lady of Mothers’ Fury). Protecting children is one of her priorities. She disses Shinji and Asuka’s fathers for not taking care of their offspring properly, and unlike her husband, she thinks that Shinji should not forgive Gendo.
** And then you have Yui “I’ll eat you for hurting my baby!" Ikari herself. She can forgive a lot of Gendo’s actions… but she will not forgive his abuse of Shinji and mistreatment of Rei unless they forgive him first.
* ''Fanfic/AdviceAndTrust'': In chapter 3, [[FieryRedhead Asuka]] had been trapped in [[{{Robeast}} Leliel]]. Shinji thought he wanted to save her no matter what, even if he had to unleash his [[HumongousMecha Evangelion]]'s power. Mama Yui heard and answered his plea. Meanwhile, Asuka thought she wanted to live and be with Shinji and asked her mother to help her. Mama Kyoko heard and answered her plea. And all of a sudden [[EldritchAbomination Leliel]] was being ripped apart by ''two'' blood-thirsty [[TheBerserker berserker]] mothers trapped into giant robots.
** In the same chapter, Misato slapped Ritsuko to the ground when she declared Asuka to be expendable.
--->''That's one of my '''kids''', you heartless bitch!''
* In ''[[http://www.fanfiction.net/s/8749207/32/EVA-Sessions-You-Can-Never-Trust Eva Sessions: You Can Never Trust]]'', a character is being real obnoxious to Asuka, getting rudely into her personal space -even though she is telling him staying away and not talking to her -- to insult her and deliver her a (pretty hypocrital) TheReasonYouSuckSpeech, when Eva-02 suddenly ''roars'' and tries to ''grab'' him. The boy bolts out of the place instantly, utterly terrified and realizing he has soiled himself. Although nobody else understands why the HumongousMecha has done that, Asuka notes that it was protecting her. This is because [[spoiler:Asuka's mother's soul is stuck inside her robot. And Kyoko wants you leaving her daughter alone.]]
* ''Fanfic/GhostsOfEvangelion'':
** Hurt Asuka and Mistato WILL kill you. [[spoiler:A rapist]] found out the hard way.
** Invoked by [[spoiler:Kyoko]] when she says a mother always protects her child.
* ''Fanfic/{{HERZ}}'':
** You don't want to know what lengths Misato will go to protect her children. She has manipulated and deceived people and her hands are stained with blood because she needed to protect Shinji and his family.
** Shinji, Asuka, and Rei are also perfectly willing to kill or sacrifice their lives to protect Akiko (Shinji and Asuka's daughter and Rei's niece).
* ''Fanfic/NeonGenesisEvangelionGenocide'': Misato's priority is ALWAYS her wards. Give her a choice between protecting her kids and helping her remaining subordinates, and she'll choose the first option.
-->"I've met her before," Sato said. "Katsuragi. And I know what drives her. Like every mother, she wants what's best for her children."
* ''Fanfic/OnceMoreWithFeeling'':
** Kyoko. When Shinji and Asuka were fighting Gaghiel Shinji could not focus properly. Then he tried to reaching out to Asuka's mother, screaming mentally that her daughter would die if she didn't help them. Kyoko reacted so furiously the backlash knocked Shinji out as Unit-02 forced Gaghiel's jaws open easily. Asuka reached a 100% synchronization with her EVA right then.
** Misato is also fiercely protective of Shinji and Asuka (Kaji notes that she was perfectly willing to kill to protect Shinji)
* ''Fanfic/TheChildOfLove'':
** After the first few weeks her baby’s welfare becomes everything for Asuka. Hurt Teri and Asuka will hurt you.
** Rei is an Auntie Bear. Don't even think of harming the Ikari-kun's baby. She is scary [[spoiler:as Gendo found out.]]
** In a DreamSequence, Yui assured her son she would protect him and his family. When Asuka [[spoiler:gave birth in Unit 01 Yui ensured that both she and her baby survived.]]
--->'''Yui''':''"I am part of you, too. I won't let him hurt you or the mother of your child. I promise. If anything happens to you or your love, I promise you that he'll regret it."''
** When Misato learnt about [[spoiler:Gendo’s scheme]], she was perfectly willing to march in Gendo’s office and put a bullet in his head to protect her wards and their daughter.
* ''Fanfic/TheOneILoveIs'': Yui Ikari went berserker every time her son was in danger... and when [[spoiler: Misato said she did not want to die because she was pregnant]] she activated Unit 01. Shinji -who had refused to sortie until then- realized his mother wanted to protect [[spoiler:Misato's]] baby as well, and he reluctantly agreed to fight.
* ''Fanfic/TheSecondTry'': [[spoiler:Asuka]] is fiercely protective of her [[AfterTheEnd post-Third-Impact]] family ([[spoiler:both Aki and Shinji]]), to the point that, in "The Final", she made an attempt to [[spoiler:strangle Gendo when he tried to interrogate her about Aki (and she came damn near close to succeeding; Gendo even seemed to be a bit unnerved).]] She also threatened Kaworu to stay away from Shinji, knowing full well what he [[{{EldritchAbomination}} was]].

[[AC:''Franchise/OnePiece'']]
* ''Fanfic/ThisBites'': Despite her professional behavior, Kureha is most definitely this for Chopper. When she finds out that Cross knows about Chopper's past and wants him to join the Straw Hat Pirates, she pins him to the bed, a scalpel inches from his throat, looming over him like death. Note how she refers to Chopper as she asks the question:
-->'''Kureha''': Do you ''actually'' care about my son, or are you just playing on his insecurities to shanghai him into your little pirate band?

[[AC:''Anime/{{Pokemon}}'']]
* ''Fanfic/ANewChanceSeries'': [[spoiler:Pidgeot]] is very protective of Ash, a year away from him hasn't diminished that, and being the leader of her own flock has accentuated that feeling. When the Fearow near Pallet Town tries to kill Ash, she goes berserk and knocks him out the sky '''in one blow'''. The she flies over to Ash and gives him a big hug.
* ''Fanfic/CommonSense'': Delia, once she finds out about the ordeals Ash has been going through because of Team Rocket, quickly takes it upon herself and commands her son's Pokémon to drive them away while he's sick.
* ''Fanfic/PokemonResetBloodlines'': Twofold example in the Arnold Interlude sidestory: Anna and her [[CanisMajor Arcanine]] do ''not'' take kindly to Team Rocket grunts threatening her son and his Growlithe.
* ''Fanfic/{{Severance}}'' is a fanfic that revolves around Delia trying to protect herself and her son Ash from his father, Team Rocket leader Giovanni. Giovanni wants to [[OffingTheOffspring kill Ash]] but Delia won't let him. She goes into a rage and tries to kill Giovanni herself, but her aim isn't right and he escapes. The story starts with Delia having been shot in the scuffle.

[[AC:''LightNovel/SwordArtOnline'']]
* ''Fanfic/IWillNotBow series'':
** In ''Blazing Revolution'' chapter 60, Chi hits Yui in the face with a [[BloodyMurder blood]] [[WhipItGood whip]], and finds herself faced with a ''very'' pissed off Asuna, who swears to tear her apart. In the very next chapter, she does exactly that.
--->'''Asuna''': You know, they say a mother grizzly bear has the strength of a hundred men when her cubs are in danger. I'm a bit different. I have strength that would make even a mother grizzly bear run in fear. And you're about to feel [[PunctuatedForEmphasis EVERY! LAST! OUNCE!]]
** In ''Blazing Generations'' chapter 66, Alicia doesn't take kindly to Akane's StageMom badmouthing Lilly, calling her a nobody and a "loser girl with no reputation." She's only stopped from giving the woman a piece of her mind by Akane herself, who [[ArmorPiercingSlap slaps her own mother]] and [[CallingTheOldManOut chews her out over her attitude]].

[[AC:''Manga/SoulEater'']]
* [[http://archiveofourown.org/works/887161 In Fever Dreams]], Maka's mother is a literal Mama Bear, being a bear witch and all. The first scene of the fic has her clawing a Kishin egg to death for going after eight-year-old Maka.
--> '''Kami''': ''(roaring)'' Not - my - daughter!

[[AC:''LightNovel/TheFamiliarOfZero'']]
* ''Fanfic/ZeroNoTsukaimaSaitoTheOnmyoji'' has Karin, who is very protective of her daughters, ''especially'' Louise. [[spoiler:When she finds out Wardes sealed Louise's magic, she is extremely angry, and utterly thrashes him in a duel when she finally gets her hands on him]].
[[/folder]]

[[folder:Comic Books]]

[[AC: ''Franchise/TheDCU'']]
* ''Fanfic/SorrowfulAndImmaculateHearts'' answers a question: Why did no super-villains travel back in time to try to murder Superman when he was a little child? They actually tried. But they never accounted for Martha Kent: "She may not be the World's Finest, but she's a mother with a shotgun, and all told that might be scarier."
* ''Fanfic/HellsisterTrilogy'' has Satan Girl. ComicBook/{{Supergirl}}'s evil twin's ''only'' redeeming trait is her willingness to hunt down whoever took her baby and ''kill them all''.
* Invoked in ''Fanfic/BruceHasAProblem''. Hugo Strange had the Hatter kidnap Harley's niece and nephew, Jenny and Nicky, so she would go crazy on the Hatter and look unstable. This way, it would seem that Harley hadn't reformed and would make Sharpe's policy seem necessary. Unfortunately for him, Harley managed to keep a level head through the kidnapping.

[[AC:''Franchise/MarvelUniverse'']]
* ''Fanfic/UltimateSpiderWoman'': Mary Jane Watson is an unusual variant in that she's a Daughter Bear. She currently has much better control over her emotions than she did when she first became a superheroine, but threatening her family and close friends is still her BerserkButton and anyone who threatens them will ''suffer''.
* ''Fanfic/APrizeForThreeEmpires'': Hurt ComicBook/CarolDanvers, and her mother Marie will hunt you down and put an extra hole in your head.
-->"You think I'm going to make apologies for Marcus? A man who virtually rapes my own daughter?" She looked cold, hard, and not at all like the mother Carol Danvers was used to. "Hell, no. If he wasn't dead, I'd find out where he was, no matter how long it took me, and shoot him down dead with your father's .38"

[[folder:Crossovers]]
[[AC:''Fanfic/AdoptedDisplaced'' -- ''WesternAnimation/MyLittlePonyFriendshipIsMagic'' MegaCrossover]]
* One of its entries is ''Another Hatchling'', with [[Franchise/{{Metroid}} Samus Aran]], who is ''very'' protective of her adoptive son, the dragon Spike. Even after he shows he's become strong enough to take care of himself. Female members of the other new families in this series are the same way.

[[AC:''Fanfic/ChildOfTheStorm'' -- ''Literature/HarryPotter'' MegaCrossover]]
* Lily Potter in as per canon, and now that [[spoiler: she's merged with the Phoenix Force, aka Destruction of the Endless, aka one of the seven most powerful beings in the universe... well, [[GodsHandsAreTied she can't do too much in normal circumstances,]]]] but suffice to say that attempting to kill her son will have ''repercussions.'' Very, very nasty ones.
* Wanda Maximoff, Harry's godmother and ParentalSubstitute ([[OneDegreeOfSeparation It's that kind of a world]]), promises to "render down to traumatized, screaming atoms" the telepath who nudged everyone's perceptions and ensured that Harry was stuck with the Dursleys for a decade. So far, so standard. However, unlike most, in ''Ghosts of the Past,'' she actually lives up to the threat, and suddenly, it's ''very'' easy to remember that she's Magneto's daughter.
* Alison Carter is a loving, kindly, and AlmightyMom and grandmom. She's also the retired [[spoiler: (formerly)]] Deputy Director of SHIELD, the first Agent 13, and a key mentor of Nick Fury himself. And as she demonstrates, retirement has not slowed her down. Suffice to say that if you hurt her children or grandchildren, she will "end you in ways that would give several gods of [her] acquaintance either ideas or nightmares."
* While not actually mother to anyone in the cast ([[spoiler: though she is Clint Barton's grandmother - and yes, it really is that kind of a world]]), Minerva [=McGonagall=] is very protective of her students. Threaten any of them, especially her Gryffindors, and you'll find yourself on the wrong end of a BraveScot who's also a master of Transfiguration, which means that she is essentially a low-scale ''RealityWarper.''
* Stephen Strange is TheArchmage and BigGood of the 'verse. His job description involves defeating and/or scamming {{Eldritch Abomination}}s, he's acknowledged across the board as ''the'' MagnificentBastard in a world with a truly epic GambitPileUp, he's second only to Loki (and possibly Wanda) in raw power, he's survived a duel with [[HumanoidAbomination Gravemoss]], crushed Grindelwald when the latter was at PhysicalGod levels thanks to various [[DealWithTheDevil dark compacts]], threw down the gauntlet to the ''entire White Council,'' and is fairly dismissive towards [[BadassTeacher Charles Xavier]]... but he's disinclined to arouse the wrath of Molly Weasley.
* Frigga, who's a lovely GrannyClassic and a wise Queen, and also, as Carol puts it, "kind of terrifying", after in the sequel, she [[spoiler: unleashes the ScourgeOfGod on Russia after the Red Room kidnap and torture Harry into their LivingWeapon.]]
* Jean Grey splits the difference between this trope and BigSisterInstinct, particularly where Harry and [[spoiler: Maddie]] are concerned. In a young woman who is unequivocally the most powerful human psychic ''ever born'' [[spoiler: jointly with Maddie, but it's hinted that while Maddie's more skilled, if anything, Jean is more powerful]], who also happens to be a FieryRedhead, this is a dangerous combination.

[[AC:''Fanfic/TheDragonThatWillPierceTheHeavens'' -- ''Manga/OnePiece''/''Manga/FairyTail'' Crossover]]
* Protagonist Hikari is a Mama Dragon of epic proportions. While not officially a mother, she is fiercely protective of Tony-Tony Chopper, the [[Manga/FairyTail Iron Dragon]] Gina Redfox, and the [[Manga/FairyTail Sky Dragon]] Sora Marvell, who all call her 'mom'. This also extends to the crew as a whole, with her taking a very maternal, caring role. Threaten any of them, and she'll HulkOut into a DraconicHumanoid form that can take out whole pirate crews with ease.

[[AC:''Fanfic/TheHeartTrilogy'' -- ''Film/TheHobbit''/''Film/TheLordOfTheRings'' Crossover]]
* The main heroine Kathryn becomes one after Kolstros and Vervenia, the twins of herself and Smaug, are born in ''Heart of the Inferno''. When Urgost calls the twins unnatural half-breeds, Kathryn gives him a magical blast.
--->'''Kathryn''': ''[[PunctuatedForEmphasis Never.]]'' [[PunctuatedForEmphasis Insult. My children.]]
* Despite being a power-hungry and [[DoesNotLikeMen misandristic]] witch as well as an AbusiveParent, [[EvenEvilHasLovedOnes Andraya looks after]] her [[MuggleBornOfMages normal daughter]] Freyja. After Freyja is killed by Smaug, Andraya attempts to gain RevengeByProxy by handing Kathryn over to Fankil (as well as to gain from the demon spells for resurrecting Freyja).

[[AC:''Fanfic/KnowThyselfThePrelude''/''Fanfic/KnowThyself'' -- ''Franchise/TheMatrix''/''Franchise/HarryPotter'' Crossover]]
* The moment Trinity sees Vernon kicking a nine-year-old Harry (initially assuming Harry's younger because he's so small), she walks up to the fat man and breaks his neck. After Harry's unplugged, the more Trinity learns about Harry's physical condition and the abuse he must have been subjected to growing up, the more she regrets not having taken more time before killing Vernon to pay him back for what he did to her new son.

[[AC:''Fanfic/MonstersInParadise'' -- ''Franchise/{{Pokemon}}''/''Franchise/{{Touhou}}'' Crossover]]
* Amber Harrison, to the core. She has one child still living in Rustboro City instead of becoming a Pokémon trainer, and she trusts few people outside of herself with the child's welfare; if anyone so much as ''looks'' at the child funny, including Yukari Yakumo, she makes her thoughts known ''violently''. This has gotten Amber in hot water in situations where her behavior wouldn't have been appropriate, however.

[[AC:''Fanfic/{{Origins}}'' -- ''Franchise/MassEffect''[=/=]''Franchise/StarWars'' [[spoiler:[=/=]''[=Borderlands=]''[=/=]''[=Halo=]'']] MassiveMultiplayerCrossover]]
* Jack steps full-throated into this trope. Brought into civilized society after a [[VideoGame/MassEffect2 criminal past]] as a biotic instructor, she will ''end you'' if you so much as look at her students the wrong way. She goes nuts on Sarah ([[NoSell to no avail]]), steps into BloodKnight territory against the [[spoiler:Flood]] after one of her students is killed, and actually cares more about the kids than her [[DrillSergeantNasty exterior]] suggests.

[[AC:''Fanfic/SayItThrice'' -- ''WesternAnimation/DannyPhantom''[=/=]''Film/{{Beetlejuice}}'' Crossover]]
* Barbara Maitland and Adam are effectively Lydia's honorary godparents, and when she finds out what the evil ghost Sanduleak intended to do to their precious girl, her reaction is... not pretty.

[[AC:''[[Fanfic/ThroughTheLookingGlassFireflyBattlestarGalactica Through the Looking-Glass]]'' -- ''Series/{{Firefly}}''[=/=]''Series/BattlestarGalactica2003'' Crossover]]
* Athena can’t show it directly as Hera’s still on Galactica, but when Jayne calls her ‘it’ after he learns that she’s a Cylon, she shows him a picture of Hera to reinforce that she is not just a ‘thing’ but a mother, soldier and wife, in that order.

[[AC:''Fanfic/ThousandShinji'' -- ''Anime/NeonGenesisEvangelion''/''TabletopGame/Warhammer40000'' Crossover]]
* Misato. Shinji quickly noticed that she was a Mama Bear and would always protect her wards, not matter what. Later on, she proves it when [[spoiler:several soldiers shoot Shinji and she leaps in the way of the bullets.]]
* Asuka. During a dream sequence she imagines herself to be a mother... and drive a battle-axe into the head of whoever or whatever threatens her and Shinji's child.

[[AC: Crossovers Without Separate Pages]]
* ''[[https://m.fanfiction.net/s/6057270/1/Harmony-In-Disarray Harmony In Disarray]]'', a ''Film/{{Transformers}}'' / ''Series/WizardsOfWaverlyPlace'' fic: ''Alex Russo'' is this towards Leigh as she once broke Galloway's nose (and her own hand!) when he pushed Leigh, and before that she was already one as far back as the beginning of the story.
* The wizards responsible for organizing the Triwizard Tournament in ''[[https://www.fanfiction.net/s/10482611/17/King-of-Serpents-Game-of-Shadows King of Serpents: Game of Shadows]]'' learn why you ''doesn't mess'' with Angeline Fowl's offspring when her son barely escapes to be enrolled into the competition. The woman is born a ''Lestrange'', and Artemis ''has'' to inherit his brown-pants inducing tendances from someone, after all.
* When she falls pregnant with the Dark One's child in ''[[https://www.fanfiction.net/s/10964874/1/Dark-Dynasty Dark Dynasty]]'', Cora decides to keep him and flatly rejects Dumbledore's proposition to give the baby to him. For the record, she's heartless - literally, as she cannot feel - and ''still'' she refuses to throw her child away, even if he's illegitimate, the offspring of a dark sorcerer and an obstacle to her projects for becoming a queen. Okay, she gets mind-wiped for her troubles, but that's the spirit, right?
* In the ''WesternAnimation/{{Megamind}}'' & ''WesternAnimation/RiseOfTheGuardians'' crossover fic ''[[http://www.fanfiction.net/s/8772736/1/Protectors Protectors]]'', Megamind (known as Teal in this fic) has been adopted by the Warden and his wife, Andrea. Andrea reaches a point in her Mama Bear-ness where the Warden is unsure whether to comfort her... or to remove any objects within her reach which could potentially become a weapon.
** And when she comes face to face with the two who [[spoiler:attempted to manipulate her adoptive son into becoming a villain:]]
--->'''Andrea:''' "Since you two obviously make poor parents, you don't comprehend how angry I am. So I'll give you a hint." ''(punches them both)'' "Try doing that to my son again, and I'll make you ''wish'' for something as ''sweet as pain''."
* In ''Croft and Son'', an AU in which Lara is portrayed as Nero's mother, has this prominently in the chapter ''[[https://www.fanfiction.net/s/13249131/6/Croft-and-Son Wolf And Cub]]'', where she spends much of it trying to protect him in a demon attack.
* The Project Motherhood series by Gamer95 has the base concept of female characters from various forms of fictional media rescuing Harry Potter (sometimes Crona from Soul Eater and Isaac from The Binding of Isaac) from intensely abusive living situations. As such, the mothers are all but guranteed to have these types of moments.
** Project Motherhood: Filia has Filia being more or less completely naive to Harry being abused and constantly thrown out of the house by his aunt. When she does catch on, however, she beats Petunia unconscious, and even before that, she attacked an armed thug that was holding Harry at knifepoint and viciously beat a Medici slave trader that was planning on selling him off.
** Project Motherhood: Cerebella has multiple instances of this, starting with Cerebella threatening Talliesin for expressing interest in adding Harry to his puppet collection and Cerebella snapping at Beatrix for attempting to take Harry as her pupil regardless of how he feels about it. Later in the story, [[spoiler:Cerebella and Feng beat the Dursleys viciously when they find out what they did to Harry, and in the end, Cerebella and Beatrix kill Vitale and Lorenzo for torturing him.]]
** Project Motherhood: Ms. Fortune has [[spoiler:Harry being separated from his adopted mother Nadia Fortune in the mall while Christmas shopping, and then he runs into his uncle, who pulls him into a back alley and beats him due to his mental state being effected by the blood wards surrounding his house. Nadia hears Harry call out for her to come save him, and when she arrives, she tackles Vernon away from Harry and begins to attack him viciously, with the implication that the only thing that stopped her from outright killing the man is Harry's crying snapping her out of her rage. Even then, she still attacks him more, then tells him he is not welcome in Little Innsmouth, essentially scaring him out of town.]]
** Project Motherhood: Painwheel starts out with Painwheel going into a berserk rage at the sight of Vernon violently beating Harry without the knowledge that she's there. In her frenzy, she stabs him, slashes at him relentlessly, gouges his eye out, then throws him out of the building and into a dumpster. Later on, after deciding to keep Harry with her, she grows enraged when Brain Drain contacts her and brings him up, threatening to mutilate him if he harms Harry in any way.
* [[WesternAnimation/TheOwlHouse Eda]] in ''[[https://archiveofourown.org/series/1891684 Owl Hearts]]'' is fiercely protective of any children who come under her care, so when she finds out that [[Franchise/KingdomHearts Sora]] became a Keyblade Wielder at 14 years old, Eda goes out to find the people who had a part to play in thrusting the responsibility onto him (namely Ansem, King Mickey, Yen Sid, Eraqus, and Xehanort) and personally [[CurbStompBattle beat them up]].

[[folder:Film -- Animation]]

[[AC: ''WesternAnimation/TheHunchbackOfNotreDame'']]
* ''Fanfic/BentOrBrokenItsTheFamilyTree'': Esmeralda protects her son Djali at all costs and gets livid when someone man-handles him.

[[/folder]]

[[folder:Film -- Live-Action]]
* The ''Film/StarTrek2009'' fic ''[[https://www.fanfiction.net/s/9694363/1/Safe-and-Sound Safe and Sound]]'' has some examples:
** The most violent is Khan's lover, Victoria, who was ready to level Starfleet when she woke up and discovered that her unborn child was gone. She then becomes this to her new surrogate daughter, Lucille, and [[spoiler: breaks Dr. Korby's arm after he kidnaps the girl]].
** Lucille's biological mother gets a moment when she [[spoiler: dies fighting Korby upon realizing the man harmed her]].
** Uhura is this towards her unborn child. When Korby tells her that [[spoiler: he intends to inject the baby with Khan's augmented blood (which could kill it), and that having her child would be useful since the baby is part Vulcan, she leaps at him in rage]].
** Kirk's mother, Winona, gets an awesome moment in the first chapter. After the events of the movie she arrives in the holding room where Khan is with [=McCoy=], and tells [=McCoy=] to leave. He does, quickly. [[TranquilFury Remaining calm the whole time]], Winona then ''punches Khan so hard he'' '''''rolls backwards off the bed'''''. And then, after she dishes out her threat, she just ''turns and walks away''.
-->'''Winona''': Do you happen to know what a mother bear does to anyone who harms her cubs?
-->'''Khan''': I do.
-->'''Winona''': So you probably have a good idea of how I'm feeling. ''(punches him in the face, and then calmly walks over to where he's landed)'' I would kill you now, but you may still be needed to save my son, so I won't. But that doesn't mean the thought has left my mind; I'm only going to say this once, and I'm going to make it very clear. If you hurt or threaten my son again, I'll come after you. I won't need Starfleet, or a Vulcan; hell, I won't even need a Klingon Empire. I'll come after you, and when I find you, I'll blast a hole straight through your cold heart. Then I'll cut off your head, and you arms, and your legs; you'll be in six pieces, and I'll bury a piece in ''one. Continent. Each.''
** [=McCoy's=] ex-wife, Pamela, could be a darker, AxCrazy example. She [[spoiler:shot and killed several security officers while defending Joanna before said daughter was forced to stun her]].
* Another ''Film/StarTrek2009'' example, this time for the fic ''Fanfic/WrittenInTheStars'': In an OffScreenMomentOfAwesome, Winona apparently, according to [=McCoy=], "turned into a Mama Bear and scared the crap outta [Khan]" in order to persuade him into giving blood to heal Fem!Kirk.
** In the same scene, Fem!Kirk's Prime counterpart muses that it runs in the family:
-->'''Kirk''': I'm guessing someone threatened Ama?\\
'''Kirk Prime''': A group of Orion pirates when she was five. Their life expectancies were shortened to ten seconds.
** Spock's mother apparently went MamaBear on the Vulcan High Council when trying to stop the other Vulcan children from bullying him:
-->'''Spock''': [Sarek] described it as the only time when the High Council showed any form of emotion.\\
'''Kirk''': Flat out terror? Well, that proves it. If you anger a mother, you must have a death wish.
* In the {{Film/Transformers}} fanfic series ''Fanfic/BlackCrayons'', Sarah Lennox proves to be this for her daughter Annabelle, telling off soldiers, politicians and Transformers alike with a passion if she even thinks that her daughter is in danger.

One in particular. The murder gang discover Lady Assassins are Mama Bears when pregnant. Not only for their unborn children. If a younger sister is deliberately targeted for killing, that's a BerserkButton for her pregnant older sister. And another might expect much from the girls to whom she is Housemistress at School. She will also fight like Hell for them as if they were her own daughters. It can only end one way for the terrorist gang. Especially when Mama Bear is assisted in the end by [[PapaWolf the soon-to-be grandfather of her child]].
* ''Fanfic/AdamWinters'' features a relatively downplayed example from Professor [=McGonagall=]; despite her reputation for not showing favouritism, she often displays a certain fondness for Adam Winters even without knowing his identity of Harry Potter. During [[spoiler:the final confrontation at Hogwarts, [=McGonagall=] hugs Adam when he returns to the school, and after he explains his true identity, she reflects that she'd like to strangle Dumbledore if he wasn't already dead for keeping so many secrets]].

* [[Series/BuffyTheVampireSlayer Buffy]]'s actions in the fanfic ''[[https://www.fanfiction.net/s/8743102/1/Ahead-of-Her-Time Ahead of Her Time]]'' deserve a mention. Over the course of the story she [[spoiler: discovers that she will have a daughter with Spike a couple of years in the future (which all has to do with some prophecy, but that's another matter entirely). This happens through time-travel hi-jinks, allowing them both to meet said daughter; an adorable three-year-old named Eden who they both love and adore almost instantly. Then when she goes to explain everything to Riley in the last chapter:]]
-->'''Riley''': [[spoiler: "Prophecy is what you make of it, Buffy. If I staked him right now, what would become of your little prophecy? Spike would be dust, you'd come to your senses, and that disgusting hybrid ''thing'' would never exist."]]
-->''[[spoiler: It was his nose that made the crunching sound this time, as Buffy's fist lashed out suddenly and smashed into cartilage. Crap, crap, crap. She'd hit Riley without even realizing what she was doing. Huh…protective instincts already in place. She just couldn't hear it, couldn't listen to him say such things about her child. About her miracle. About Eden. She could change the prophecy. Maybe that was the truth. But all it took was Buffy's mind pulling into focus the so-recent image of the little girl, all blue eyes and soft skin and sweet little lips, and yes, even her tiny razor-sharp fangs, to know that she'd never, ever wish her away. Quite the opposite, actually. She would do everything in her power to make sure she did exist. Even if that meant putting her faith in one de-fanged but currently soulless vampire. Even if that meant letting herself admit that she loved him.Even if it meant throwing Riley away, tossing out her one shot at a "normal" life.]]''
-->'''Buffy''': [[spoiler: "Did you even see her, Riley? If you had, you wouldn't dream of saying that. And if you want me to leave this apartment before you're a bruised and battered heap on the floor, you won't say it again."]]
* In a ''Series/CriminalMinds'' fanfiction ''To live again'' Alex Blake becomes this to Annie. With her (biological) son [[spoiler:already died in canon]] it's especially understandable.

* In the ''Series/BattlestarGalactica2003'' fanfic ''Fail Better'', Lucia is this to Laura and all the Adamas (being married to their ancestor, the first William Adama). She's one of the goddesses of light and a generally sweet woman (if a bit rebellious) who strongly believes in free will, but if you threaten her family you better run. Fast.
* In the ''Series/StargateAtlantis'' fanfic ''I See the Stars'' Diana Weir is a grandmother example of this, especially towards Ada.
-->'''Diana''': ''*to Jonah*'' "They're the future - our future and the planet's. I won't let them suffer like we did."

* Every female character with a child in ''Fanfic/TheLegendOfSpyroANewDawn'' and its sequels, even the BigBad Deadlock. Given most of them are female Dragons, it seems it's just a natural trait for them to have. Cynder takes it up a notch, due to her own horrific childhood making her want to protect her child from suffering the same thing. The only subversion is [[GodSaveUsFromTheQueen Queen Gorgon]], the Queen of the Naga that Deadlock overthrew.
* Epona is obviously not her mother, but in "[[https://www.fanfiction.net/s/13189099/1/The-Legend-Of-Zelda-Ocarina-Of-Time The Legend of Zelda: Ocarina of Time]]", Malon is grabbed by a Gerudo Assassin, who threatens Link with her. He manages to back the assassin into Epona, who bites her and forces her to let go.
* Fanfic/ImperfectMetamorphosis: Kotohime, though typically maintaining a veneer of amicable dutifulness, [[NoHoldsBarredBeatdown has no quarter]] towards anyone who harms officers [[DaChief under her command]], even if that individual happens to be [[PersonOfMassDestruction Marisa Kirisame]].
** In turn, Marisa's mother figure, Mima, is terribly protective of her. Marisa tends to get uncomfortable when Mima voices her concerns regarding the witch's mortality, and how to solve that little "problem". Of course, this doesn't stop Marisa from using it to [[spoiler:coerce Mima into Yukari's god-killing hit squad]].
* A ''VideoGame/StarTrekOnline'' example from "Fanfic/{{Frostbite}}", of the AMotherToHerMen variety. Kanril Eleya is supremely pissed off when she finds out that the Breen have been holding part of her crew prisoner, [[spoiler:and doesn't have much of a problem with jolting Dalsh Ruul around to make the knife Tess stuck in the Breen's back move about.]] It's to the point where Eleya's actual {{codename}} is "Mama Bear".
* In Fanfic/Gensokyo20XX, try to use and manipulate Yukari's love for the children she cares to get her to kill them, try it and you'll find you won't succeed because, mentally ill or otherwise, Yukari will try to kill you. Seija learned the hard way.
** A pregnant Ran is a more downplayed example in ''Life in Gensokyo Village'' in chapter 10 but we clearly know she is a force to be reckoned with, stating that if Yukari and Reimu's birth-mother were to quarrel over who can have Reimu that she was to take Chen and Reimu and stay somewhere else.
* Marjorie Wilde-Wayne begins showing this in the Arkham City fanfiction ''The Last Laugh'' to her unborn child and [[spoiler: rushing in to protect her newborn daughter, Sammie, when Azrael delivers his prophecy to Bruce in the finale]].
* In the ''Franchise/MortalKombat'' fic "Fanfic/InWithTheOldOutWithTheNew", Sonya Blade, who is quite violently protective of her daughter Cassie as it is, is madder than hell after learning that [[spoiler:Kano, who had kidnapped Cassie in revenge for her defeat of him, ended up raping her]].

She's armed with only a baseball bat, with an awesome shout-out.
-->'''Bernadette:''' Get away from her...''PITCH!'' ''(whacks him with baseball bat)''

--> '''Harley''': ''(advancing on Joker with the hammer)'' You filthy ''scum sucking'' CREEP! You lousy, good for nothing, son of a ''weasel!'' You ''hurt'' him!
--> '''Joker''': Now, Harley...I can explain!
--> '''Harley''': Go on! Try it! I ''dare'' you! ''(hits Joker in the stomach with the hammer, then grabs him by the shirt and pulls him up to her face)'' I love you, Puddin', but you stab my baby again and even ''Batman'll'' feel sorry for you! Got it?

Aelita is ''furious'', calling Jeremie out on his hypocrisy by pointing out that he thinks of her as a person and that she and the little girl (named Anya) were created with the exact same programming guidelines, even out-and-out stating she refuses to let Jeremie hurt her little girl. Fortunately Jeremie is talked around, helped by the fact that Anya [[WhatBeautifulEyes has her mother's eyes]].

* The ''WesternAnimation/{{Rango}}'' fanfic ''Fanfic/OldWest'' has [[DeterminedHomesteader Grace Glossy]] who won't allow anything to happen to her only child Teddy. When she's forced to accept [[RecruitingTheCriminal Rattlesnake Jake's]] protection over her home, only the possibility of Teddy becoming a target of mercenaries makes her tolerate the outlaw she (initially) despises. In addition to that, she [[HeroicFireRescue rescues Mrs. Bigby and her baby from a conflagration]] because she can't bear to hear a child burning to death. When Bad Bill and his gang beat up Teddy as a warning to her, she goes [[UnstoppableRage absolutely livid]] and [[NoHoldsBarredBeatdown beats them all up]] entirely by herself. [[spoiler:Before Teddy was born, his nine unhatched siblings were killed by robbers who in turn were killed by Grace.]]
* In ''Fanfic/TeenageMutantNinjaTurtlesOutOfTheShadows'', threatening Kagome and/or the Turtles around Kasumi is ''not'' a good idea.

* ''Fanfic/BurningBridgesBuildingConfidence'': As Alya, Lila, and [[AdultsAreUseless Mrs. Bustier]] learn the hard way starting in Chapter 6, bullying Cole or her cousin Marinette will ''not'' go over well with her mother Adelaide, especially since Adelaide was a lawyer before becoming the CEO of a cybersecurity company and is all too willing to resort to litigation to make sure people get punished for their actions. [[spoiler: When Alya attacks Cole, Adelaide gets the law to officially label it as an ableist hate crime since Alya used her belief that Cole was faking her missing eye as a reason for it, and also sues the school for enabling the environment for the attack in the first place. She also sues Mrs. Bustier for [[CrimeOfSelfDefense her attempt to victim-blame Cole for the attack]] and is also aiming at making sure Bustier permanently loses her job [[note]] Following the incident, Damocles suspended Bustier from her job to punish her for her blatant favoritism towards the attacker. However, the school board hasn't decided whether or not to fire her yet.

[[folder:My Little Pony: Friendship is Magic]]
* [[WesternAnimation/MyLittlePonyFriendshipIsMagic Twilight Sparkle]] in general is this in almost any fic where she's a mother. Be they adopted (''[[Fanfic/TheNuptialverse Families]]'', ''Fanfic/GuardianAngel'') or biological (''Fanfic/MyLittleMommies'', albeit not via the traditional way), mess with her kids at your own peril. Other repeat examples include Princess Celestia, Princess Cadance, Twilight Velvet and Derpy Hooves, among others.
* ''Fanfic/AceCombatTheEquestrianWar'': When the griffins raid Ponyville in chapter 4 to kidnap fillies and Dinky is taken, Derpy doesn't hesitate to fight three griffins ''all by herself''.
* ''Fanfic/AftermathOfTheGames'':
** In the sequel ''Integration'', after Sci-Twi [[spoiler: almost gets kidnapped]], her sister-in-law Cadance (Sci-Twi's parents [[ParentalAbandonment were killed]] by a DrunkDriver when she was thirteen, and Shining Armor and Cadance [[PromotionToParent gained custody of her soon afterwards]].) spends the entire night next to her bed holding a giant baseball bat in case the Changelings attempt to do it again.
** During the parent meeting in "Humans V", it's made perfectly clear that Cadance sees Sci-Twi as her own child, and [[BerserkButton is VERY offended]] when Rarity's mom says [[InnocentlyInsensitive she doesn't know what it's like to see your child get bullied]].
-->'''Cadance''': "Don't you dare assume that I care for Twilight any less just because she came from somewhere else!"
* ''Fanfic/CircusDays'': After finding out the danger Spike was put in at the end of the story, Princess Celestia personally shows up alongside her guards to make sure he's okay.
* ''Fanfic/ChronomistressOutOfTime'': Derpy who, upon thinking that her daughter might be in danger, gets out of a LotusEaterMachine with sheer force of will, then proceeds to take on an entire hive of changelings.
* ''Fanfic/ADiplomaticVisit'':
** A milder example when Twilight finds out about 'the molt', and immediately informs Spike that he'll be staying indoors for the duration of that event, since his scent would attract predators and she doesn't want anything bad to happen to him. Later, when she finds out ponies had been giving him dirty looks because of his species when they lived in Canterlot, she displays visible concern and asks him why he didn't tell her about it sooner.
** Even though it's not her filly, when Spoiled Rich starts yelling at Diamond Tiara, Twilight sees the fear on the younger pony's face and ''immediately'' steps in to give Spoiled a verbal smackdown.
** In the third story, ''Diplomacy Through Schooling'', Twilight's protective instinct over her students and teachers is enough to [[spoiler: make her go ''past'' Mama Bear to full-on OneWingedAngel and curb-stomp Tirek when he destroys her school and she thinks he's killed them all]].
* ''Fanfic/EscapeFromTheMoon'':
** In the sequel ''The Mare From the Moon'', Celestia decides to send Spliced to stay in Ponyville with Twilight, but makes it very clear what will happen if the visiting alicorn if she harms Twilight or anypony (or non-pony). Spliced’s reaction: "That mare is ''scary''."
** Twilight is the same when it comes to Spike, warning Spliced that if her plan to help him get ready for what's basically puberty doesn't work out like she promised, Spliced will have to explain the entire thing to Spike, all of Twilight's friends, Princess Celestia, Princess Luna, Dragon Lord Ember and her father, former Dragon Lord Torch. And then, as an implied threat and the final nail in the coffin, she informs Spliced that she and her friends once banished a being who hurt Spike into the prison realm of Tartarus.
** [[spoiler:''Scavenge For the Future'' has a retroactive example with Spliced Genome, who castrates the pony who threatened her many-times-great-granddaughter with his own gun. Neither of them knew of the relationship at the time though - Spliced herself wasn't told who it was she'd saved until shortly afterward.]]
* ''Fanfic/MirrorsImage'': Chrysalis. When her last daughter died from emotional neglect (she'd been left with Filthy Rich and his wife, but wasn't able to get the love she needed when they divorced), she made sure the ponies who were supposed to be raising her went to prison, and ''stayed there''. Plus, there's the whole "invading Canterlot to recover her daughter" thing.
** Her mother, Queen Amethyst, was a KnightTemplarParent and a {{Jerkass}}, but she still went after Celestia for [[spoiler:breaking her daughter's heart. And she won.]]
** Twilight Velvet, who is very protective of Twilight and refused to let her be forced into an arranged marriage. [[spoiler:She ends up dying to save her daughter.]]
* ''Fanfic/{{Nosflutteratu}}'': When Twilight Sparkle discovers Fluttershy is a vampire, she naturally winds up pouring over her books for any information she can find on the subject. Rainbow Dash drops by just as Twilight has reached and is reading about methods to dispose of a vampire. Rainbow reacts... poorly.
* ''Fanfic/PastSins'': Do not hurt Nyx, physically or psychologically, or Twilight ''will'' demonstrate exactly why she is [[PhysicalGod Celestia's]] protege. [[spoiler:She'll even go so far as to attack Celestia herself if she thinks it necessary, though there are limits to even the Mama Bear power-up so fortunately nothing much comes of it.]]
* ''Fanfic/PonyPOVSeries'': [[spoiler:[[FanNickname Ditzy Doo]]/[[AscendedMeme Derpy Hooves]] grabs a mop and proceeds to beat the living tar out of [[BigBad Princess Gaia]]'s birds who have come to carry her daughter away. She actually ''scares the crap'' out of the BigBad doing this!]]
** [[spoiler:The [[BadFuture Dark World]] version of her also qualifies. She kept going for a ''thousand years'' of non-stop pain and suffering to keep her end of Discord's bargain to turn Dinky back (Discord turned her into a muffin). When the [[HeelFaceTurn redeemed Twilight, Applejack, and Rarity]] rescue her along with Spike, she joins them to reunite the Elements so she can uncurse Dinky, being revealed as an awakened Element of Loyalty due to her loyalty to her daughter.]]
** [[spoiler:Rarity goes MamaBear when her baby sister Sweetie Belle is threatened. She even fights Cheerilee - who's acting as TheDragon to Princess Gaia - one-on-one and her zeal is enough to put them on equal hooves. Her rage was great enough that she almost ''killed'' Cheerilee and only stopped when the others reminded her that Cheerilee was BrainwashedAndCrazy at the time and they had to be careful.]]
** [[spoiler:[[AdaptationalBadass G1 Mimic]]'s DyingMomentOfAwesome is one of the most popular moments in the entire fic, due to the fact she managed to bust out Discord's tooth, becoming the ''only'' mortal pony to ever truly hurt him. We find out in "Origins" that she did it to protect Celestia and Luna, who were her ''daughters''. It didn't help Discord essentually just emotionally curbstompped Celestia ForTheEvulz.]] The moment is preceeded by this BadassBoast:
--> [[spoiler:'''Mimic''']]: "You float one inch towards my daughters I will kill you and seal your spirit in one of my horseshoes!"
** [[spoiler:Exploited by Discord with his earthly mother Shady. He knows she loves him, and thus powers her up with an Element of Chaos, allowing her to be his loyal TheDragon and bodyguard, safe in the knowledge she loves him too much to let anything happen to him. Unfortunately for him, he didn't realize she might love him enough to realize he'd gone too far and had to be stopped.]]
** [[spoiler:Starlight Sparkle (Twilight Velvet), when she sees her son AND daughter have been brainwashed by Chrysalis reacts this way and attacks her. Sadly, a gifted unicorn whose never been in battle verses a veteran alicorn level creature is STILL a lopsided fight, but she ''does'' manage to wound Chrysalis.]]
* ''Fanfic/{{Progress}}'' and spin-offs: Princess Celestia will ever so calmly, politely, and ''nightmarishly'' deal with you if you threaten her sister Luna.
* ''Fanfic/RainbowDoubleDashsLunaverse'': Ditzy Doo goes totally ballistic in ''A Hard Bargain'' when some gangsters kidnap Dinky to the point of [[HighAltitudeInterrogation lifting one miles into the air and dropping him ]] to find out where they were hiding her.
--> "Kindness has limits.” Ditzy answered. “and I’ve reached mine.”
* ''Fanfic/RealityChecksNyxverse'': Twilight absolutely FLIPS when Nyx is threatened [[spoiler:and nearly killed]] in ''Nightmare Night and Nyx''. [[spoiler:She's only stopped from committing murder by Celestia showing that Nyx was still alive.]]
** Celestia shows a bit of this in ''Alicornundrum'' when she threatens Lord Blueblood.
-->'''Celestia:''' ''' ''"DID YOU IMAGINE FOR A SECOND THAT I WOULD REFRAIN FROM BRINGING MY FULL POWER AND WRATH TO BEAR AGAINST ANYONE WHO TRIED SUCH A THING WITH MY MOST BELOVED STUDENT?"'' '''
** Twilight Velvet finally gets her [[BadAssFamily Sparkle Clan brand]] moment of awesomeness in this manner in the same fic.
-->'''Velvet:''' "You won't have to worry about what Celestia will do to you because the last thing you will see in this world will be me ''taking a bite out of your still-beating hearts.'' Oh, and don't think I won't do it. My grandson is a dragon. I know how to get rid of the bodies."
* ''[[http://www.fimfiction.net/story/16028/shipping-and-handling Shipping and Handling]]'': Ditzy Doo gets another dose of this, although since it's a shipping/comedy fic rather than an adventure story, both the trigger and the flipout are relatively tame (but we dread to think what would happen if her daughter Dinky was seriously threatened). She relatively meekly endures a verbal beatdown by [[JerkAss the unicorn Glow, who's kind of a bitch]], until Glow insults Dinky. At this point, Ditzy a) goes berserk, b) throws a serving pan at Glow's head, and c) tells her where to stick it.
--->'''Derpy''': ''"You can insult my eyes, my intelligence, and my disposition all you want, but I will NOT tolerate unkind words about my daughter! Now take it back, you overbearing, self-centered mule!"''
* ''Fanfic/SixBridesForTwoSisters'': Cadence was like this to Twilight Sparkle when they were younger. An older, unfamiliar colt is walking away with the filly you're foalsitting with promises of fun and candy? Poor [[MistakenForPedophile Shining]] [[RelativeError Armor]] never saw the GroinAttack coming. (Fortunately for Cadence and Shining's future romance, explanations and apologies were made afterward.)
* ''Fanfic/TheMLPLoops'':
** Derpy, both Awake and unAwake, is this - in one loop, an accident of Discord's gone wrong causes her (while unAwake) to declare her intent to move out of Ponyville and take Dinky with her, rather than see her hurt again. Since Dinky is one of Ruby Pinch's few friends, this encourages Berry Punch to take her own steps to prevent it, by any means necessary. It eventually results in Berry being hospitalized by a pissed-off Derpy. Fortunately, this also causes Derpy to snap out of her rage. Once back to her normal self, she apologizes to Berry for her actions.
** Berry Punch, for her part, is willing to risk violent Derpy-induced beatdowns to ensure her daughter Ruby Pinch's safety.
** Twilight, as usual, for Spike and Nyx.
** Cadance becomes one after Flurry Heart is born.
** Fluttershy. It doesn't matter if her adopted son Leman Russ could quite literally chew up anything that threatens him and spit it right back out, hurt him and ''you. will. pay.''
* ''Fanfic/TheNuptialverse'':
** In the second story ''Families'', Twilight [[spoiler: rips a tree out of the ground and uses it as a club against some teenage dragons threatening Spike!]] In the next chapter, [[spoiler: Garble (the teen dragons' leader) makes Twilight so furious that she ''[[BurningWithAnger goes into]] [[Franchise/{{Pokemon}} Rapidash]]-mode and [[EyeScream shoves a burning piece of wood through his eye!]]'' ]]
** This line says it all:
--> '''Twilight Sparkle''': [[PunctuatedForEmphasis "Get. Away. From. My. Son!"]]
** In the side story ''Outrage'', Twilight Velvet chews out Luna and Applejack (and by extension Celestia and the rest of the Mane Five) when she learns what happened to Twilight at the rehearsal, and how she was basically abandoned by everyone. When she confronts Applejack on what happened she punches her right in the face and calls her a bitch [[PunchedAcrossTheRoom (though Applejack does retaliate for this)]]. Velvet and Nightlight need to be locked in their room for the night to calm down until Twilight finally talks to them about what happened in the morning.
* ''Fanfic/ThePartyNeverEnded'': Derpy has another prominent moment of this when she uses thoughts about Dinky to motivate herself to help fend off the storm.
* ''Fanfic/TheSweetieChroniclesFragments'': Twilight again, in the chapter based on ''Fanfic/OfMaresAndMagic'' (Sweetie Belle is traveling from one alternate dimension to another, and they're all based on various fanfics), when Sweetie is almost killed by a werewolf.
--> '''Twilight:''' "Nopony, no creature, no ''monster'' threatens ''my'' student!"
* ''Fanfic/TheTwilightChild'':
** Princess Celestia makes it quite clear off the bat that if Twilight Twinkle is someone trying to hurt Twilight Sparkle, then she's going to find herself at the business end of an angry PhysicalGod. It's also the reason she's left out of the loop regarding [[spoiler:the Changelings]], because Twinkle knows she'll instantly confront them, even if her fighting skills are somewhat rusty after years of disuse.
** Trixie makes her opinions on an angry Ditzy Doo quite clear.
--> "An angry single mother? Trixie would much rather face an Ursa Major with only a wet towel at her disposal."
** Future!Fluttershy. When the Changelings attack her house, she manages to knock several of them out.
* ''Fanfic/VengeanceOfTheStar'': After watching her adopted son Spike killed by assassins, Twilight unleashes a magic burst strong enough to obliterate her room entirely and kill two of her assassins. The blast was so strong that ''Rainbow Dash could see it from Ponyville.''
* ''Fanfic/WhatHaveYouDone'': After Twilight had been kicked out of the [[Recap/MyLittlePonyFriendshipIsMagicS2E25ACanterlotWeddingPart1 Canterlot]] [[Recap/MyLittlePonyFriendshipIsMagicS2E26ACanterlotWeddingPart2 Wedding]] the only pony who acknowledges her absence is Twilight's mom, Twilight Velvet. When [[OOCIsSeriousBusiness she can't find her in the library]] and when her friends don't know where she is, Velvet runs out of the reception only to be stopped by Princess Celestia. Velvet attempts to be respectful while trying to leave and look for Twilight, until Celestia keeps blocking her, and trying to reassure her claiming to know Twilight as well as she does. Velvet snaps, and tells Celestia that 1) You are the ruler of Equestria, but you are not Twilight's mother and 2) ''back off'':
---> '''Princess Celestia''': "Twilight Velvet. Your daughter is fine. I assure you. I know my student just as well as you know your daughter and we both know that she’s-"
---> '''Twilight Velvet''': "Most definitely '''not''' fine."
---> '''Twilight Velvet''': "I do ever so apologize, Princess, but I must correct you on one little thing. Twilight may be your student, but she is my daughter. And she will always be my daughter. I know Twilight. I’ve known her for far longer than you have, and I know her far better than you ever can, because there are things she would never bare to you. I know her pain, I know her fears, things that you could never understand, because you are a goddess. A being above us. And I respect that. I honor you as my ruler, but I will never honor you as my sister, or as a fellow mother. Now, '''move aside''', so I can save the mare that you helped break."
** And Celestia ''does''. Even the guards were amazed.
* ''[[http://www.fimfiction.net/story/214973/where-is-my-love Where Is My Love?]]'': Derpy again. She even quotes [[Franchise/{{Alien}} Ellen Ripley]] when she sees Dinky being threatened by [[spoiler: Amber Vain, who wants to [[MurderTheHypotenuse kill both Derpy and Dinky]], clearing the way for Vain to be with Prince Blueblood]].
--> '''Derpy:''' “Get away from her, you bitch!”

[[/folder]]

* Epona obviously her mother, but in "[[https://www.fanfiction.net/s/13189099/1/The-Legend-Of-Zelda-Ocarina-Of-Time The Legend of Zelda: Ocarina of Time]]", Malon is grabbed by a Gerudo Assassin, who threatens Link with her. He manages to back the assassin into Epona, who bites her and forces her to let go.

* [[WesternAnimation/TheOwlHouse Eda]] in ''[[https://archiveofourown.org/series/1891684 Owl Hearts]]'' is fiercely protective of any children who come under her care, so when she finds out that [[Franchise/KingdomHearts Sora]] became a Keyblade Wielder at 14 years old, Eda goes out to find the people who had a part to play in thrusting the responsibility on him (namely Ansem, King Mickey, Yen Sid, Eraqus, and Xehanort) and personally [[CurbStompBattle beat them up]].

* ''[[https://www.fanfiction.net/s/12520482/1/Fire-and-Blood-a-My-Hero-Academia-Story Fire and Blood]]'': Inko Midoriya is a massive one to her son Izuku and her [[ParentalSubstitute "may-as-well-be" son Shouto]] . Despite her lack of combat experience or a powerful Quirk, she is entirely willing to throw down with (meaning "attack with a rock") [[spoiler:the second-best pro hero on Earth]] to protect them.

* Protagonist Hikari is a Mama Dragon of epic proportions. While not an actual mother, she is fiercely protective of all the crew, and takes on a motherly role with Tony-Tony Chopper, the [[Manga/FairyTail Iron Dragon]] Gina Redfox, the four Kung-Fu Dugongs from Alabasta, and [[spoiler:the Sky Dragon Sora Marvell]]. Threaten any of them, and she'll HulkOut into a DraconicHumanoid form that can take out whole pirate crews with ease.

** Wanda Maximoff, Harry's godmother and ParentalSubstitute ([[OneDegreeOfSeparation It's that kind of a world]]), promises to "render down to traumatized, screaming atoms" the telepath who nudged everyone's perceptions and ensured that Harry was stuck with the Dursleys for a decade. So far, so standard. However, unlike most, in ''Ghosts of the Past,'' she actually lives up to the threat, and suddenly, it's ''very'' easy to remember that she's Magneto's daughter.
** Alison Carter is a loving, kindly, and AlmightyMom and grandmom. She's also the retired [[spoiler: (formerly)]] Deputy Director of SHIELD, the first Agent 13, and a key mentor of Nick Fury himself. And as she demonstrates, retirement has not slowed her down. Suffice to say that if you hurt her children or grandchildren, she will "end you in ways that would give several gods of [her] acquaintance either ideas or nightmares."
** While not actually mother to anyone in the cast ([[spoiler: though she is Clint Barton's grandmother - and yes, it really is that kind of a world]]), Minerva [=McGonagall=] is very protective of her students. Threaten any of them, especially her Gryffindors, and you'll find yourself on the wrong end of a BraveScot who's also a master of Transfiguration, which means that she is essentially a low-scale ''RealityWarper.''
** Stephen Strange is TheArchmage and BigGood of the 'verse. His job description involves defeating and/or scamming {{Eldritch Abomination}}s, he's acknowledged across the board as ''the'' MagnificentBastard in a world with a truly epic GambitPileUp, he's second only to Loki (and possibly Wanda) in raw power, he's survived a duel with [[HumanoidAbomination Gravemoss]], crushed Grindelwald when the latter was at PhysicalGod levels thanks to various [[DealWithTheDevil dark compacts]], threw down the gauntlet to the ''entire White Council,'' and is fairly dismissive towards [[BadassTeacher Charles Xavier]]... but he's disinclined to arouse the wrath of Molly Weasley.
** Frigga, who's a lovely GrannyClassic and a wise Queen, and also, as Carol puts it, "kind of terrifying", after in the sequel, she [[spoiler: unleashes the ScourgeOfGod on Russia after the Red Room kidnap and torture Harry into their LivingWeapon.]]
** Jean Grey splits the difference between this trope and BigSisterInstinct, particularly where Harry and [[spoiler: Maddie]] are concerned. In a young woman who is unequivocally the most powerful human psychic ''ever born'' [[spoiler: jointly with Maddie, but it's hinted that while Maddie's more skilled, if anything, Jean is more powerful]], who also happens to be a FieryRedhead, this is a dangerous combination.

[[AC:''Fanfic/MonstersInParadise'' -- ''Franchise/{{Pokemon}}/''Franchise/{{Touhou}}'' Crossover]]

[[AC:''Fanfic/MonstersInParadise'' -- ''Franchise/{{Pokemon}}/''Videogame/TheTouhouProject'' Crossover]]

* ''[[https://m.fanfiction.net/s/6057270/1/Harmony-In-Disarray Harmony In Disarray]]'', a ''Film/{{Transformers}}'' / ''Series/WizardsOfWaverlyPlace'' fic: ''Alex Russo'' is this towards Leigh as she once broke Galloway's nose (and her own hand!) when he pushed Leigh, and before that she was already one as far back as the beginning of the story.
* ''Fanfic/MonstersInParadise'': Amber Harrison, to the core. She has one child still living in Rustboro City instead of becoming a Pokémon trainer, and she trusts few people outside of herself with the child's welfare; if anyone so much as ''looks'' at the child funny, including Yukari Yakumo, she makes her thoughts known ''violently''. This has gotten Amber in hot water in situations where her behavior wouldn't have been appropriate, however.
* In ''Fanfic/{{Origins}}'', a ''Franchise/MassEffect''[=/=]''Franchise/StarWars'' [[spoiler:[=/=]''[=Borderlands=]''[=/=]''[=Halo=]'']] MassiveMultiplayerCrossover, Jack steps full-throated into this trope. Brought into civilized society after a [[VideoGame/MassEffect2 criminal past]] as a biotic instructor, she will ''end you'' if you so much as look at her students the wrong way. She goes nuts on Sarah ([[NoSell to no avail]]), steps into BloodKnight territory against the [[spoiler:Flood]] after one of her students is killed, and actually cares more about the kids than her [[DrillSergeantNasty exterior]] suggests.
* In ''Fanfic/TheDragonThatWillPierceTheHeavens'', a ''Manga/OnePiece'' and ''Manga/FairyTail'' crossover, protagonist Hikari is a Mama Dragon of epic proportions. While not an actual mother, she is fiercely protective of all the crew, and takes on a motherly role with Tony-Tony Chopper, the [[Manga/FairyTail Iron Dragon]] Gina Redfox, the four Kung-Fu Dugongs from Alabasta, and [[spoiler:the Sky Dragon Sora Marvell]]. Threaten any of them, and she'll HulkOut into a DraconicHumanoid form that can take out whole pirate crews with ease.
* ''Fanfic/AdoptedDisplaced'', a ''WesternAnimation/MyLittlePonyFriendshipIsMagic'' multi-crossover series: One of its entries is ''Another Hatchling'', with [[Franchise/{{Metroid}} Samus Aran]], who is ''very'' protective of her adoptive son, the dragon Spike. Even after he shows he's become strong enough to take care of himself. Female members of the other new families in this series are the same way.
* Barbara Maitland is given this role in the ''WesternAnimation/DannyPhantom''[=/=]''Film/{{Beetlejuice}}'' crossover ''Fanfic/SayItThrice.'' She and Adam are effectively Lydia's honorary godparents, and when she finds out what the evil ghost Sanduleak intended to do to their precious girl, her reaction is... not pretty.
* Two examples in ''Fanfic/ThousandShinji'':
** Misato. Shinji quickly noticed that she was a Mama Bear and would always protect her wards, not matter what. Later on, she proves it when [[spoiler:several soldiers shoot Shinji and she leaps in the way of the bullets.]]
** Asuka. During a dream sequence she imagines herself to be a mother... and drive a battle-axe into the head of whoever or whatever threatens her and Shinji's child.
* In the ''WesternAnimation/{{Megamind}}'' & ''WesternAnimation/RiseOfTheGuardians'' crossover fic ''[[http://www.fanfiction.net/s/8772736/1/Protectors Protectors]]'', Megamind (known as Teal in this fic) has been adopted by the Warden and his wife, Andrea. Andrea reaches a point in her Mama Bear-ness where the Warden is unsure whether to comfort her... or to remove any objects within her reach which could potentially become a weapon.
** And when she comes face to face with the two who [[spoiler:attempted to manipulate her adoptive son into becoming a villain:]]
--->'''Andrea:''' "Since you two obviously make poor parents, you don't comprehend how angry I am. So I'll give you a hint." ''(punches them both)'' "Try doing that to my son again, and I'll make you ''wish'' for something as ''sweet as pain''."
* The wizards responsible for organizing the Triwizard Tournament in ''[[https://www.fanfiction.net/s/10482611/17/King-of-Serpents-Game-of-Shadows King of Serpents: Game of Shadows]]'' learn why you ''doesn't mess'' with Angeline Fowl's offspring when her son barely escapes to be enrolled into the competition. The woman is born a ''Lestrange'', and Artemis ''has'' to inherit his brown-pants inducing tendances from someone, after all.
* When she falls pregnant with the Dark One's child in ''[[https://www.fanfiction.net/s/10964874/1/Dark-Dynasty Dark Dynasty]]'', Cora decides to keep him and flatly rejects Dumbledore's proposition to give the baby to him. For the record, she's heartless - literally, as she cannot feel - and ''still'' she refuses to throw her child away, even if he's illegitimate, the offspring of a dark sorcerer and an obstacle to her projects for becoming a queen. Okay, she gets mind-wiped for her troubles, but that's the spirit, right?
* Lily Potter in ''Fanfic/ChildOfTheStorm,'' as per canon. And now that [[spoiler: she's merged with the Phoenix Force, aka Destruction of the Endless, aka one of the seven most powerful beings in the universe... well, [[GodsHandsAreTied she can't do too much in normal circumstances,]]]] but suffice to say that attempting to kill her son will have ''repercussions.'' Very, very nasty ones.

* ''Fanfic/TheHeartTrilogy'', a series of ''Film/TheHobbit'' and ''Film/TheLordOfTheRings'' fics, has a couple of examples.
** The main heroine Kathryn becomes one after Kolstros and Vervenia, the twins of herself and Smaug, are born in ''Heart of the Inferno''. When Urgost calls the twins unnatural half-breeds, Kathryn gives him a magical blast.

** Despite being a power-hungry and [[DoesNotLikeMen misandristic]] witch as well as an AbusiveParent, [[EvenEvilHasLovedOnes Andraya looks after]] her [[MuggleBornOfMages normal daughter]] Freyja. After Freyja is killed by Smaug, Andraya attempts to gain RevengeByProxy by handing Kathryn over to Fankil (as well as to gain from the demon spells for resurrecting Freyja).

* ''Fanfic/ADiplomaticVisit'': Even though it's not her filly, when Spoiled Rich starts yelling at Diamond Tiara, Twilight sees the fear on the younger pony's face and ''immediately'' steps in to give Spoiled a verbal smackdown.

* In ''[[https://www.fanfiction.net/s/5012739/1/Reunion Reunion]]'', Haruka's response to learning that the woman who molested [[Manga/LoveHina Keitaro]] when he was only ten years old is to start carrying a handgun. When said woman actually manages to break in and rape him, Haruka confronts her at gunpoint and threatens to kill her if she ever sees her again.

[[folder:Film - Live-action]]

* When Bellatrix's three-weeks-old baby son disappears from Lestrange Manor after an Auror raid in ''[[https://www.fanfiction.net/s/11594215/1/The-Curious-Case-of-Romulus-Lestrange The Curious Case of Romulus Lestrange]]'', she became absolutely ''desesperate'' to find him. Unfortunately for the Longbottoms, she remembered Frank was there when baby Romulus was taken...
