Some kind of monster is terrorizing folks. After defeating or almost killing it, the cast follows the menace's trail back to its lair.

There it turns out the hostile critter has a very good reason for its actions, such as it was just protecting its cubs/litter. Extra points if they're cute.

Typically, the heroes inform the harassed populace about the creature's motivations, which may involve ShamingTheMob, and a suitable arrangement is arrived at to resolve the situation peacefully. Woe betide the townie or hero who took one of its litter as a PetBabyWildAnimal, unless it's somehow become attached to them and convinces mommy to spare their life. Nursing a wounded fledgling back to health generally grants you a reprieve from momma's wrath, whether via karma, or because mom's smart enough to understand that you healed her child and grateful that you did. Sometimes the mom will be grateful enough to help out the person who helped her child(ren).

This trope can be expanded to cover any noble, maternal or protective behavior by an [[AliensAndMonsters alien or monster]] that is misunderstood as predatory and/or aggressive.

There's also a fairly common inversion where the heroes battle one or more monsters before discovering the InsectQueen or MonsterProgenitor, who is several steps up the SortingAlgorithmOfEvil from her offspring -- and is now [[YouKilledMyFather out for revenge...]]

Compare with ItCanThink, when a monster is more intelligent than they seem.

[[folder:Anime & Manga]]
* Diva from ''Anime/BloodPlus'', although if you consider what she did to become pregnant...
* The [[TagalongKid Detective Boys]] in ''Manga/DetectiveConan'' were imperiled by a monstrous bear when they went hiking in the mountains for mushrooms. (Turns out the bear was already quite pissed due to an overeager hunter who killed one of her cubs and hung its corpse in an attempt to lure her out in the open.)
* In ''Anime/HeroicAge'', the Iron Tribe's forces realize too late that the Bronze Race's (a race of giant space bugs that the Silver Tribe uses as mooks) homeworld is a lightly defended nursery planet. In other words, they carpet bombed alien babies.
* The chimera ants of ''Manga/HunterXHunter'' fit this trope in several ways. Most of them kill humans simply to feed and protect their Queen Mother, who in turn is doing it all for the wellbeing of her progeny. After the King is born, the more noble ants protect and nurture him in the same way, even organizing a sort of country-wide Battle Royale to find him worthy prey.
** Although it had nothing to do with the reason the lead character was tracking it down, he stumbles upon the ant he wanted to kill while [[spoiler: it was busy treating the critical wounds of a 10 year old girl (accidentally injured by the protagonists) because she was important to the King (and the ant, by extension.) One of the characters notices that the ant acts just like a mother with her cub]].
** The beginning of the series has a flashback showing the origin of Gon's foxbear friend. As a child, Gon wandered into the forest and encountered an angry mother foxbear. Kite killed the foxbear to save Gon, then berated him for not noticing the telltale signs of the mother foxbear's presence. When he sees the foxbear's cub, he decides to kill it, since its resentment towards humans for killing its mother means it will likely grow up to be a maneater. Gon immediately embraced the cub and pleaded with Kite to let him raise it even as it scratched and bit him. This powerful demonstration of Gon's FriendToAllLivingThings nature convinces Kite that Gon could be a great Hunter someday.
* In the anime ''Manga/{{Naruto}}'' a flashback to the character Haku's childhood shows him threatened by a stray dog for food. After he defeats it, you see the cubs growling at him, as it turned out it was trying to get food for its babies.
* Pretty much all the insects in ''Manga/NausicaaOfTheValleyOfTheWind'', in the manga moreso than the film. They only attack Asbel because he crash-lands into a nest, and the scene in the well in a Dorok village, with Nausicaa petting a giant insect and leaving it under its eggs is quite touching. [[spoiler: And not to forget that the Crypt of Shuwa is itself a mommy of sorts, containing in itself seeds for the post-purification world and a new race of humans.]]
* ''Anime/{{Pokemon}}'':
** The Team Rocket scientist Dr. Namba tried to capture Lugia by kidnapping its child in one multi-part episode; after Ash - as well as James, Jesse, and Meowth, [[EnemyMine who sided with them]] - helped recover the young one, Lugia became an AndroclesLion towards all of them.
** ''The 13th movie'' has a mother Zoroark and her child, a male Zorua.
** Also in ''Manga/PokemonAdventures'', Blue (or Green in the original Japanese) tried to catch a Kanghaskhan, but the Kanghaskhan would not stay in the Poké Ball. Red revealed why: it had a baby cub, and it was hurt.
* Minor subversion in ''Anime/SaberMarionetteJ'': We meet the cute cub first, ''then'' the scary parent.
* ''Anime/DragonBallZ'': Gohan (as the Great Saiyaman) tried to take a baby dinosaur away from Satan City before its parents showed up.
* The first bear Gin and Daisuke kill in ''Manga/GingaNagareboshiGin'' turns out to have had cubs nearby. Despite the cubs also being [[BigBad Akakabuto's]] cubs, Gin tries (unsuccessfully) to protect them from John.
* In ''LightNovel/TheRisingOfTheShieldHero'' the dragon killed by Ren adopted a young demi-human named Wyndia several years earlier. After his death Ren didn't find out, but the villagers who incited him to kill the dragon stole its treasures and enslaved Wyndia. When Ren finds out he's devastated.

[[folder:Comic Books]]
* This is one of three tests given to ComicBook/TheMightyThor in the arc leading up to "The Reigning". He passes it handily, proving that he's not just DumbMuscle.
* During the Plunder Island arc in Thumble Theater, ComicStrip/{{Popeye}} learns the gender of Alice the goon when, just as he's about to finish the fight, a smaller goon runs up and cries out, "Mama!"
-->'''Popeye:''' ''Mama?!''
* The Thing in ComicBook/FantasticFour faced this when a cosmic entity suppressed the elements of the Fantastic Four's personalities that supposedly made them effective (Mr. Fantastic's genius, Invisible Woman's compassion, The Human Torch's decisiveness, The Thing's courage) and he had to face a "monster". Trying to creep up on it and get the advantage of surprise, he finds out it was only trying to protect its child...and impresses the entity by showing compassion.
* Creator/EmilyCarroll's ''ComicBook/ThroughTheWoods'' has "The Nesting Place", where [[spoiler:"Rebecca" is actually TheWormThatWalks [[FaceStealer inside Rebecca's stolen skin]] and wants Bell's skin for her children, so they can leave their spawning pool]]. Bell seizes on this and [[TalkingTheMonsterToDeath saves herself]] by horrifying the monster with stories of the [[TheyWouldCutYouUp dangers]] its children would face.
* One version of the purpose of the Celestials (cosmic energy beings encased in 2000 foot tall suits of armor) in Marvel comics is that they 'lay' an 'egg' in suitable planets. Their experiments on the sentient life on those planets tend to produce super-beings . . . to more effectively protect the planet until the egg is ready to hatch and consume it. [[note]]This version also claims Galactus, the Destroyer of Worlds, is the natural predator of Celestials, destroying their larvae by consuming their host-planets. Galactus has tried to consume Earth four times.[[/note]]

[[folder:Film - Animated]]
* In ''Animation/LeafieAHenIntoTheWild'', a hen who raises an orphaned duckling learns this about the weasel who had killed the duckling's parents and nearly her on one occasion, having accidentally discovered the baby weasels and realizing they are hers when the weasel screams at her to leave them alone. This leads to both mothers reaching an understanding with one another, both protecting their child/children. [[spoiler: In the Korean ending, which was deemed too sad for most translations, after the duck leaves with his new flock the hen consents to letting the weasel kill and eat her, as the weasel is starving and cannot nurse her babies without food. The weasel is clearly shocked by this gesture, and is in tears when she kills the hen, having no other choice.]]
* There's a quick bit in ''Disney/{{Pocahontas}}'' where John Smith is about to shoot a huge, menacing bear. Pocahontas stops him, and the pair follow the bear at a discreet distance to a cave, where they see it is a mother with two cubs.
* ''Disney/BrotherBear'' has the protagonist find out late in the film [[spoiler:that the bear he killed was the mother of the bear cub who's been following him around]].
* ''WesternAnimation/HowToTrainYourDragon'' has dragons continually raiding the Viking village of Berk, but Hiccup and Astrid discover [[spoiler:that the dragons are trying to feed a huge Queen Dragon who otherwise would have eaten them.]] Thus in the climax, it is only when [[spoiler:dragons and humans work together]] that they are able to end that threat and a new alliance of the species is born.
* In ''WesternAnimation/TheLandBeforeTime: The Great Valley Adventure'', the heroes (a bunch of young, talking herbivorous dinosaurs) accidentally lose one of Duckie's parents' eggs in a nest in the Mysterious Beyond. They pick one of the eggs, take it back to the Great Valley, and take care of it themselves, but what finally hatches out is a baby Sharptooh (specifically a ''Tyrannosaurus rex''). Sharpteeth have been [[BigBad antagonists]] since the first movie but they decide to keep him, call him "Chomper", and go on their merry way (they become friends and Chomper inadvertently saves their lives). But they end up getting pursued by not only one full-grown Sharptooth this time, but two - the [[MamaBear T-Rex mommy]] and the [[PapaWolf T-Rex daddy]]. But upon the returning of their baby, they end up not hurting the protagonists and actually save them from "eggnappers", smaller, vicious egg-stealing dinosaurs who had caused the entire mess in the first place when they took Duckie's parents' egg. [[TheBusCameBack Both Chomper and his parents return in the fifth movie.]] While the gang hides from them, another unrelated Sharptooth stumbles across the island and hunts them down. Chomper attempts to aid them and the new Sharptooth turns its attention towards him, just in time for his parents to show up and beat the snot out of it. To round it all off, Littlefoot saves Chomper's life in the process, so his parents do not harm any of them.
* Used to provide the [[EmotionalTorque sucker]] [[KickTheDog punch]] in the free (as in money and as in beer) movie ''WesternAnimation/{{Sintel}}'' by the Blender Foundation.
* In ''Animation/{{Gandahar}}'', a huge reptilian beast attacks [[spoiler:the transport in which TheHero and his {{Love Interest|s}} are held captive, then proceeds to fuss over them as if they were her hatchlings]].

[[folder:Film - LiveAction]]
* ''Film/{{Aliens}}'': The theme of the film is mother vs. mother. (Ripley vs. the Alien Queen.)
* According to [[WordOfGod interviews]], the ''Film/{{Cloverfield}}'' monster [[spoiler: is an infant who swam up to the surface and is terrified because he misses his mommy. If that sequel ever gets off the ground, she will definitely definitely appear]].
** [[spoiler:In the sequel Film/{{TheCloverfieldParadox}} the mommy does indeed show up in the end. In her one scene where she stands up and roars, presumably with grief over her dead baby, it's shown that she is large enough to reach her head above the clouds.]]
* Subverted in ''Film/{{Dragonslayer}}'': The dragon has a clutch of hatchlings, which are just as vile as the serpent that spawned them, and are accordingly slaughtered by the hero. And then ItsPersonal.
* In the mock documentary ''Film/DragonWorld'', the frozen mummified dragon corpse the paleontologists have been studying is revealed three-quarters through to have been immature (despite the 20-foot wingspan), prompting the search for Mama Dragon's corpse (which is found and is the size of a small passenger aircraft).
* The 1998 ''Film/{{Godzilla|1998}}'' remake.
** There's also the original Japanese Franchise/{{Godzilla}} who is a daddy (Though, Mrs. Godzilla is out there somewhere). Harming Godzilla's son is a [[PapaWolf VERY bad idea]]
** The female Muto from ''Film/{{Godzilla 2014}}'' has hundreds of glowing orange eggs in her belly, [[spoiler:and lays them when she meets up with the male. Their destruction distracts from their double-teaming of Godzilla]].
* ''Film/{{Gorgo}}'' has fun playing with this one. Gorgo is captured and brought to London pretty early on, and then his mommy shows up, destroys London, rescues her baby, and the two of them swim away.
* ''Franchise/JurassicPark'':
** ''Film/TheLostWorldJurassicPark'' film has concerned mother AND father T-Rexes chasing our heroes all the way round the island, and then around San Diego, all because they have a baby T-Rex.
** In ''Film/JurassicParkIII'', the group is pursued and hunted by velociraptors as [[WhatAnIdiot a member of the group]] [[TooDumbToLive has stolen two eggs from their nest]]. Upon returning the eggs and communicating with them via a replica velociraptor resonating chamber, the velociraptors leave without harming the group. The protagonist notes that dinosaurs are not monsters, but are sophisticated and intelligent animals. [[HumansAreBastards Man was the real monster]], since the egg-thief wanted to sell the eggs for a million bucks.
* In ''Film/RiseOfThePlanetOfTheApes'', Bright Eyes goes on a rampage when she's hauled from her pen against her will. Only after she's been shot and killed do her keepers realize she'd just given birth and was trying to get back to her newborn.
* In the beginning of the Douglas Fairbanks ''Film/SinbadTheSailor'', {{Sinbad}} tells his audience of his encounter with the Roc, whose nest he invaded. He feared for his life against the giant bird, but "Wondrous, wondrous, this miracle of motherhood!" the Roc came only to warm her egg.
* ''Film/SuckerPunch'': "Remember; don't wake the mother." [[OhCrap They do.]]
* A shark in ''Film/Jaws3D'' is captured, blamed for the attacks, and then put in the water park as an exhibit, promptly dying from the stress early in the film. Then its gargantuan mother shows up...

* Inversion: The tale of ''Literature/{{Beowulf}}'', in which the hero slays a very dangerous monster, and its even more dangerous Mommy goes on a RoaringRampageOfRevenge.
* A different subversion seems in order in the short story "Honor is All" -- set in the ''Literature/{{Dragonlance}}'' RolePlayingGameVerse, it follows a noble knight who tracks and slays a dragon, and discovers that it has a hatchling. Just as he is about to do away with the infant dragon, however, he discovers that the creature he just killed was not a ferocious [[AlwaysChaoticEvil white dragon]], but an albino [[ColourCodedForYourConvenience silver dragon]]--one of the most powerful servants of Good, branded as a monster because of a tragic mutation.
** This is a case of artistic license, because not only are white and silver dragons very different physically, but albinism would not change the reflectiveness of its scales.
* In Creator/StephenKing's ''Literature/{{IT}}'', the titular monster turns out to be a female, but that actually makes things worse rather than better.
* Subverted in both the novel and film versions of Michael Crichton's ''Literature/TheLostWorld1995'' (one of the few plot points they have in common). The team takes an infant tyrannosaur back to the trailer to fix its broken leg; unfortunately, neither Mommy nor Daddy is very grateful for their saving the baby's life.
* This was how ''Literature/IAmLegend'' ended: Turns out some of the vampires were trying to live their lives, and the last surviving human was the "real" monster.
* The ending of Dav Pilkey's ''Dogzilla'' has the titular monster now accompanied by her puppies.
* In Terry Goodkind's ''Literature/TheSwordOfTruth'' series, the hero makes an ally of an extremely dangerous dragon by helping her save her egg from the bad guy.
* The old picture book ''Pickle Chiffon Pie'' involves three (naturally) princes sent on a quest. The geeky-but-nice prince nearly brings back a thoroughly unthreatening monster to make the titular pie for a king ([[ItMakesSenseInContext It Makes (More) Sense In Context]]) until he notices its children, which are even more UglyCute than the parent, peeking sadly from behind trees, whereupon he of course lets it go (and gets the king's daughter anyway). Causes some rather dramatic FridgeLogic--''why'' didn't he just bring the kids too?--but still a good story.
* In "[[Literature/TheJungleBook Rikki-Tikki-Tavi]]", the titular mongoose defends an Anglo-Indian family from a vicious cobra. Upon finding out that she had laid a clutch of eggs, he finds them, kills all the eggs but one, uses the last one to lure the cobra away from his owners and then kills the cobra and, apparently, the last egg as well.
* Played straight in ''Literature/ReapersGale'', book seven of the ''Literature/MalazanBookOfTheFallen'', without the bonus points for cuteness. Onrack tracks an emlava, the story's equivalent of a steroid-using saber-tooth tiger, and kills it, only to realize after the fact that its behavior was not typical of a hunting emlava. It had several cubs and his party takes over stewardship of them. Said cubs are less than cute, requiring that the characters regularly check to ensure no limbs are in range of them.
* Happens twice in ''Literature/WarriorCats'': once with a badger and her cubs trying to settle in [=ThunderClan=] territory, and once with a dead fox they found which happened to have a den full of cubs.
* Brian Lumley applies this trope to some Eldritch Abominations in the short story "Concrete Surroundings".
* In ''Literature/{{Sinbad}}'', the shipwrecked title character finds a roc's nest. Leaving the egg alone, he is able to tie himself to the roc and get off the inhospitable isle. Later, he's part of a ship that finds another egg; ignoring Sinbad, the crew chop it open and eat the chick. Back at the ship, Mommy (and Daddy) show their displeasure. With dropped boulders.
* During ''{{Literature/Dinoverse}}'' two characters encounter an [[NeverSmileAtACrocodile immense crocodile]] who's more than a match for them even working together. They're incapable of doing her much damage, but she lets them go when they make it clear that they'll back away from her and the baby crocodiles crawling all over her.
* In Creator/EvaIbbotson's ''Literature/WhichWitch'' there is an adorable subversion. When a witch tries to get the giant kraken to appear, all that turns up is three chubby mermaids who carry something that looks like a gelatinous handbag -- turns out it is the kraken baby, who is an orphan since mommy monster was killed, and had been cared for by the mermaids, who are more than happy to get rid of the responsibility.
* In ''Literature/PhoenixRising'', the heroine Kyri visits a village that's under attack from giant centipede creatures; it turns out that they're only trying to retrieve their eggs, which one of the villagers gathered up thinking they were interesting rocks. Fortunately for all concerned, Kyri works it out in time to settle the matter before there's major bloodshed.

[[folder:Live-Action TV]]
* ''Franchise/StarTrek''
** ''Series/StarTrekTheOriginalSeries''. The episode "The Devil in the Dark" uses this plot. While the Horta are neither cute nor cuddly (they look kind of like living lava flows[[note]]or that's how the story describes them; due to the limited special effects budget, viewers may be excused for thinking they look more like lumpy and somewhat dusty Oriental rugs[[/note]], and the children are still unhatched eggs at the point of the episode), Spock's relaying of the mother/broodwatcher's emotions is one of the most powerful moments in ''Star Trek'' history and the civilized resolution to the conflict is one of the happiest ones. (As a side note, the [[HumansAreUgly creature remarked that it found a humans' appearance "revolting"]].)
** Similarly in the ''Series/StarTrekTheNextGeneration'' episode "Galaxy's Child," a huge interstellar alien attacks the ship. When the crew retaliate, accidentally killing the alien despite using minimal force, they discover that it attacked because it was pregnant and about to give birth. Then the baby (which they help deliver by phaser C-section) gloms onto the ship and starts to ''nurse.'' HilarityEnsues.
* Also happens in the ''Series/{{Farscape}}'' episode "Genesis" where the monster makes doppelgangers of the crew.
* Inverted/parodied in the ''Series/AmazingStories'' episode "Mummy, Daddy", where an actor trapped in a highly-constricting mummy suit frantically attempts to reach the hospital where his wife is giving birth. His task is further complicated by 1. a hostile band of redneck hicks and 2. a real mummy.
* Not quite a monster, but the weasel that infests the school and makes the janitor miserable in ''Series/NedsDeclassifiedSchoolSurvivalGuide'' turns out to be "a ''girl'' weasel!" and to have been looking for a nest all along. She is subsequently adopted with her young as secondary mascots.
* The [[BigCreepyCrawlies giant bug]] in the ''Series/{{Sanctuary}}'' episode "Instinct".
* ''Series/HerculesTheLegendaryJourneys'' approached this from a different angle. Herc goes about Greece slaying beasts and whatnot, and only ''after'' that he meets Echidna, the Mother of All Monsters, a gigantic tentacle-armed Lamia. Later he finds and rescues her husband Typhon, Father of All Monsters, a giant played by Glenn Shadix who was trapped by Hera so that Echidna would go evil and be willing to send her children after Herc. When they reunite, the two ... erm... [[{{Squick}} Squicky]].
* Parodied in ''Series/{{Outnumbered}}''; 6-year-old Karen invokes this trope to heap guilt on her mother for setting out a mouse-trap, arguing that the dead mouse was probably a mummy and all its babies will now starve.
* ''Series/{{Charmed}}'' has a variation in the episode 'Little Monsters', in that 'Monster is a '''Daddy'''', and is really a human who inadvertently disfigured himself while trying to use magic in order to make himself strong enough to take back his HalfHumanHybrid son from a group of [[MonsterOfTheWeek manticores]].
* 1970's ''Series/KolchakTheNightStalker'' episode "The Sentry". Kolchak investigates a rampaging monster in an underground facility. He discovers that during the drilling of a tunnel the creature's eggs were taken. When the creature gets its eggs back, it leaves peacefully.
* ''Series/{{Supernatural}}'' had Eve, the Mother of Monsters come back to Earth and freak major damage when [[spoiler: Crowley and Castiel]] start kidnapping her children (i.e. monsters like vampires and werewolves) and torturing them for information.
* ''Series/{{Angel}}'' had "Fredless" where a giant bug demon was terrorizing the crew, and after Fred chopped off the head of another demon that had been attacking as well, it was discovered that the bug demon simply wanted its hatchlings, which had been inside the other demon's head.
* ''Series/KyoryuSentaiZyuranger'' had Goda, a legendary monster that lived underground. She was initially seen terrorizing some hunters and then attacking the heroes, but it turns out that she was just protecting her eggs. [[spoiler:After Bandora makes her think that the Zyurangers destroyed her eggs, tricking her into selling her soul, the heroes are reluctantly forced to kill her.]]
* ''Series/DoctorWho'' in "Hide" had a variation of this where the monster that had been chasing them in a pocket universe merely wanted to reach the main universe where its mate had accidentally wound up. Once the Doctor deduced this, he was more than happy to help out.
-->'''The Doctor''': It's not a monster story, it's a love story!

* This trope is pretty much the whole point of the Music/{{Voltaire}} song "Crusade", in which a dragon slayer makes the realization that the dragon he killed was a father. [[spoiler: This is later applied to the singer's son as he goes off to crusade against the Muslims, [[{{Dehumanization}} who are described in the same terms as the dragons were to him]]]].
-->''Son, hear you father clear deep in your heart Son, know your enemy As I would have them know My son.''

[[folder:Other Sites]]
* ''Wiki/SCPFoundation'', [[Characters/SCPFoundation Characters/SCPFoundation]], [[http://www.scp-wiki.net/scp-2141 SCP-2141 ("Primordial Wyrm")]]. SCP-2141 is a mother, and it's using the body of a human woman to gestate its young.

[[folder:Tabletop Games]]
* ''Marvel Super Heroes Adventure Game'' (SAGA System) Adventure 3 ''Fantastic Four: Fantastic Voyages''. In the adventure "Wild at Heart", a monster emerges from the earth in a small town and starts destroying the place. If the heroes don't send the creature back home quickly enough, a much larger monster appears and starts searching for the smaller one - it's the smaller monster's mother, and it [[MamaBear won't like it if the heroes have hurt its child]].
* The main book of ''TabletopGame/{{Space 1889}}'' has an illustration showing just this.
* Garganuta are [[{{kaiju}} overwhelmingly large monsters]] found in the Kara-Tur setting of the ''TabletopGame/ForgottenRealms''. They dwell on remote islands and rarely bother humans, but one way to ensure they ''do'' is threaten their offspring. Gargantua have been known to swim ''thousands'' of miles if they have to if their hatchlings are kidnapped, coming after the abductors in a fury resembling a force of nature. (Which they ''are''.)

[[folder:Video Games]]
* The Nue, the first major boss in ''VideoGame/BreathOfFireIII'', is only attacking people to get food for its cubs (it's a really bad season). In an expansion on the trope, the cubs are all dead, but the Nue couldn't tell, being driven mad with grief, and refused to accept that they were dead, to further emphasize the sadness that the vicious beast was really a grieving parent.
* ''VideoGame/ChronoCross'' actually uses this in a ''positive'' way: After having to kill a monster that's the LastOfHisKind, they find that its last act was to give birth (hopefully to a self-sufficient brood), and continue the species. Oddly, you only discover this if you have a certain character in the party, and doing so deprives them of their LastDiscMagic.
* Played for horror instead of sympathy in ''VideoGame/ChronoTrigger''. Discovering that [[spoiler: Lavos is sending its children out to consume ''even more'' worlds after consuming the protagonists']] only underscores how urgently you need to kill them.
* ''VideoGame/FinalFantasyVII'' allows you to examine a nest of chicks with treasure inside. Attempting to take the treasure forces you into an easy fight with the chicks' mother, after which you can steal it freely. However, even Cloud is guilty about doing it, and he becomes a lot less popular with his team-mates afterwards. Hacking into the relationship mechanics shows that this scene has no effect on anything driven by relationship points.
* The Dynablade segment of ''VideoGame/KirbySuperStar'' uses this plot. Dynablade is attempting to gather food for her chicks, destroying crops in the process. After Kirby defeats her, he realizes the truth and helps feed the chicks by taking them to Whispy Woods, a boss that attacks by throwing an endless supply of apples at the player. Dynablade would later aid Kirby in the Revenge of Meta Knight segment.
* ''VideoGame/TheMovieMonsterGame'' for the Commodore 64 has this as one of the objectives. As soon as the parent finds the baby, the InstantWinCondition has the closing scene where everyone realizes the monster just wanted to recover the baby. Available to all characters, even the marauding military robot and pollution-spawned blob creature.
* Early in disc 2 of ''VideoGame/StarOceanTheSecondStory'', the party has to hunt down and tame a Psynard to use as the GlobalAirship. When they discover it has young to care for, they decide to leave it be and find another way, but the Psynard, whom they saved just before this discovery, agrees to let them ride it around anyway. She just takes her kids with her.
* Kat and Ana's chapter in ''VideoGame/WarioWare: Smooth Moves'' basically plays this straight, where the giant rampaging oni [[PapaWolf was trying to get his son back]].
* A rather... uncommon example of this trope is in ''VideoGame/ParasiteEve'', where Aya points her gun at Eve, then smiles and points it away once Eve points out she's pregnant. [[spoiler:A twisted EldritchAbomination-to-be with the game's FinalBoss inside her]], but still a mama.
* In ''VideoGame/TalesOfTheAbyss'', one of the first bosses you face is a Lyger, who turns out to be female and protecting a clutch of eggs. Although the party still kills her, doing so is treated with some moral wieght, unlike the other monsters they cut down in spades, due to the Queen just trying to raise and feed her young. [[spoiler:To make matters worse, the Queen also happened to be the ''[[RaisedByWolves adoptive]]'' mother of [[LittleMissBadass Arietta the Wild]], who spends the rest of the game in a tragic quest to avenge her "mommy."]]
* In the second chapter of ''VideoGame/LaPucelle'', you may end up killing the guardian of the forest. If you return there in the third chapter, Prier finds the monster's child, a cute bear cub, and chooses to take care of it to make amends. If she returns the cub to the forest, she'll gain a new spell.
* At the end of the First Chapter of ''VideoGame/{{Mother 3}}'' [[spoiler: Flint goes to kill the Drago that killed Hinawa, only to be stopped at the last second by its baby]].
* The order is reversed in ''VideoGame/CallOfCthulhuDarkCornersOfTheEarth'', where after meeting the cute (if creepy) little girl, you meet her mother, [[spoiler: a savage purebred Deep One locked in the attic, who proceeds to break out, maul you, and then kill the little girl]].
* In ''VideoGame/FinalFantasyTacticsA2'', there is a quest sequence concerning endangered monster species. One of the missions has you protect an attacking Mamatrice and her chicks in a barfight from the corrupt bar-owner.
* In ''VideoGame/DragonQuestVIII'', when you're helping [[TheScrappy Prince]] [[JerkAss Charmless]] acquire an Argon Heart for his rite of passage, you eventually come across a Great Argon Lizard that's heavily implied to be the parent of all the regular Argon Lizards. Charmless, of course, [[KickTheDog orders you to slaughter it because he's not satisfied with the regular Argon Hearts you've found.]]
* In ''VideoGame/EVOSearchForEden'', the final boss of Chapter 4, the Yeti, turns out to have a wife ([[SequentialBoss who tries to take her revenge]]) and a child (whose descendant tries to get even with you in Chapter 5).
* The arcade game ''VideoGame/SavageQuest'' has a T-Rex mother whose clutch of eggs were stolen by a shaman (Karn) and his fellow cavepeople. An interesting twist is ''you'' play as the T-Rex and beat the living hell out of everything in your path to try to get those eggs back.
* In ''VideoGame/PanzerDragoon Orta'', Orta is attacked by what is known as an Els-Enora, a large flying creature. After defeating it, its young fly up to it, shrieking in what's most likely despair; Orta, realizing the "monster" was just hunting her for food, immediately regrets what she has done. [[KickTheDog Then Abadd flies in and finishes off the mother, as well as murdering her children.]]
* In one of Shara's later requests in ''VideoGame/RuneFactory3'', she takes an injured Wooly home with her. In the next request, you discover that the Wooly's mother is searching for her baby, and when Shara and baby run into Mommy, your character barely manages to avert an all-out brawl.
* One of the minibosses of ''VideoGame/KingdomOfLoathing's'' Nemesis Quest is Argarggagarg the Dire Hellseal. After you beat him, you find out that he's actually female and has a child. Because of the general tone of the game, your character's response is roughly "Score! A new familiar!"
* Why is Steelfeather, an unusually large and tough hippogryph, menacing the Alliance settlement of Fort Wildervar in WoW? [[spoiler:Because the town is uncomfortably close to her nest.]]
* Darkly subverted in ''VideoGame/ResidentEvil2''. G, the constantly mutating creature that's chasing you, is revealed to be doing it because he's actually MadScientist William Birkin, and you are travelling with his daughter, Sherry. However, the only reason he wants her is because he needs a compatible host for the G-virus to reproduce, and Sherry is the only one available.
* As a BrickJoke in the ''VideoGame/{{Portal 2}}'' DLC, the [[spoiler: bird that Atlas and P-body fight lays three eggs. [=GLaDOS=] then 'adopts' them, to make them killing machines]].
* Comes up in a quest in ''VideoGame/{{Fallout 4}}''. If you go to the Museum off Witchcraft, you happen upon the dismembered remains of a Gunner private just outside with an ApocalypticLog, recalling how her squad was attacked by... ''something'' and they were forced to flee inside. [[spoiler:Inside the Museum is a gigantic Deathclaw who serves as a boss. After killing it, you find out that the giant monster followed the squad all the way from Lynn's Wood (several miles away) because the squad stole the Deathclaw mother's eggs, and of the egg cluster, only one is left intact. You can hand it in to the Gunner's client for a hefty sum, or return it to the Deathclaw nest. If you choose the latter, a slightly smaller Deathclaw (presumably her mate) pops out just as you go to put it back, and he leaves you alone, knowing you're just trying to return her baby. [[PapaWolf If you try to take it back, however...]]]]
* In ''VideoGame/WorldOfWarcraft's'' Howling Fjord, there's quest named "We Call Him Steelfeather" which features you being tasked with learning why a hippogryph, Steelfeather, has been attacking Fort Wildervar for food. You learn that Steelfeather has a nest and is in fact a "she". The questgiver acknowledges that he wouldn't want to move a nest over a new neighbor, either, and tells the trapper next to him that he won't be getting a Steelfeather trophy after all.
* The whole premise and playstyle of ''VideoGame/Dota2'''s [[GiantSpider Broodmother]] is centered around this trope, injecting her spiderling spawn into enemies and using them to fight for her.
* A minor side quest in the Emerald Graves, in ''VideoGame/DragonAgeInquisition'', has a soldier ask the Inquisitor to please deal with an extremely aggressive great bear which has been marauding and attacking the camps. When the bear is tracked to its cave... sure enough, it's got three cubs. Notably, the cubs are almost as large as regular great bears, and the mother is ''huge.'' Unfortunately, the only way to resolve the quest is to kill all four of them.

* In several of Fredrik K. T. Andersson's (often NotSafeForWork) artworks, a human adventurer is surprised to see the unholy child of some (still alive) creature. With the added twist that [[spoiler:[[AnythingThatMoves he's the father]]]]. Links [[http://andersson.elfwood.com/Family-Gathering.2524339.html here]] and [[http://andersson.elfwood.com/DragonLayer.2524328.html here]].

* ''Webcomic/TheOrderOfTheStick'':
** [[InvertedTrope Inverted]] when [[TheSpock Vaarsuvius]] failed to consider that the dragon [[AmbiguousGender (s)he]] was killing might be a ''son.'' Several hundred comics later, his mom hunts [[AmbiguousGender him/her]] down...and [[MamaBear she is]] ''[[RoaringRampageOfRevenge pissed]].''
** And then the dragon targets Vaarsuvius's partner and children for revenge, [[spoiler: and this trope is played horribly straight from the dragon's point of view. [[JumpingOffTheSlipperySlope And all of its relatives]]]].
* ''Webcomic/SluggyFreelance'' plays with this in the BizarroEpisode. A father bear takes his cub with him while roaming camp sites so people won't touch him believing he's a momma bear protecting her cub. Then Bun Bun takes the baby bear hostage (leaving it in the care of Kiki's chipmunks), to force the bear to rob a bank, with a teddy bear, to make the security guards think he's just a momma bear protecting her cub. Then he lets the baby bear go, just in time for the real momma bear to show up.
* In ''Webcomic/AwfulHospital'', after Ms. Green helps Nobody Nose to get rid of his kidney stones, they are both attacked by the Kidney Stone Mother who wants revenge for the death of her children. Trying to politely inform her that kidney stones usually aren't living creatures does nothing to cool her down.
** [[BerserkButton Which then angers Mrs. Green to the point that she seems eldritch herself]]. Cue CurbstompBattle.
* The [[http://t3.gstatic.com/images?q=tbn:ANd9GcRJqAhEn-osGF-1jFZUYNst8DEJbd8Si2tGXezvPkZGyejTdcMq White Steel Eels]] from ''Webcomic/TowerOfGod'' are said to be usually docile. But they are only ever seen during their mating and breeding season, and therefore stay in mind as highly aggressive beings.
* This trope fuels a continent-wide CycleOfRevenge in ''Webcomic/DraconiaChronicles''. Dragon kills tiger warrior who had kids who murder dragon who had kids and on and on [[ForeverWar since time immemorial]].

[[folder:Western Animation]]
* This also was the plot of one of ''WesternAnimation/TheHerculoids''' segments on ''Space Stars''.
* ''WesternAnimation/SouthPark'':
** [[PlayingWithATrope Played with]] in the "Woodland Critter Christmas" episode. One of the adorable (but annoying) woodland critters is pregnant with their Savior, but a terrifying mountain lion is trying to kill the mother.

It gets even worse, since [[spoiler:the critters' Savior is actually TheAntiChrist]].
** Further played with in the "Jewbilee" episode. A bear is seen dragging off several Squirts (Jewish Cub Scouts). The beast turns out to be a literal MamaBear, who took the children back to her den for a birthday party for her cub.
* ''WesternAnimation/{{Ben 10}}'':
** In the original series episode "The Krakken", the monster was protecting its eggs. Milked a bit when, after the eggs are recovered, the hero prevents the monster from finishing off the poacher that had stolen them, and she relents and leaves peacefully.
** In an ''Alien Force'' episode, the monster mommy is BEN HIMSELF via a mix of his alien transformations with that species's asexual reproduction.

* In ''WesternAnimation/AvatarTheLastAirbender'', Sokka adopts a cute little critter called "[[FluffyTheTerrible Foo Foo Cuddlypoops]]", who turns out to be a baby [[http://avatar.wikia.com/wiki/Saber-tooth_moose_lion Saber-Toothed Moose lion]]. ''He'' is harmless - [[MamaBear his mother isn't]].
* Played for ironic laughs in ''WesternAnimation/BuzzLightyearOfStarCommand''. An animal loving doctor saves the life of a young worm creature in front of its man-eating mother. Buzz expects that the mother will now be indebted to them and spare their lives. However, the worm does not share his point of view and still tries to eat the pair. Later, the doctor rebukes him for his way of thinking: "They still only see us as prey!".
* One episode of ''WesternAnimation/TheLifeAndTimesOfJuniperLee'' had a gigantic stone eating lizard rampaging around the park eating statues. After June tries to take it on and is beaten and knocked unconscious, the monster thinks she's the baby because earlier in the episode, June had gotten the baby's scent on herself. This resulted in the mother trying to feed June rocks that were chewed up in her mouth (similarly to a mother bird), and cleaning her by licking June with her massive purple tongue.
* {{Creator/Filmation}}'s ''ComicBook/{{Superboy}}'' did this twice in its first season.
** "The Deep Sea Dragon". A diver exploring a shipwreck finds a pearl in a chest. After he removes it and takes it to his ship on the surface, the ship is attacked by a seagoing dragon. It turns out that the dragon was genetically engineered, and ''she'' left her egg in the wreck for safe keeping.
** "Visitor From The Earth's Core". While Superboy and Krypto the Superdog are on an expedition to the Earth's core, Krypto finds a glowing black rock and Superboy takes it back to the surface to be analyzed.

They hatch the egg with their heat vision and return the baby creature to its mother.
* ''WesternAnimation/ThePowerPuffGirls'':

** In another one, a monster was just looking for her baby.
* The ''WesternAnimation/MyLittlePonyFriendshipIsMagic'' episode "Boast Busters" [[spoiler:inverts the trope]]: That [[EldritchAbomination big, scary]] [[CelestialBody star]]-{{bear|sAreBadNews}} [[spoiler:was really just a very young cub in need of a bottle and a nap. We see Mama only in an AnswerCut; it's a good thing she ''[[{{Kaiju}} didn't]]'' [[MamaBear show up]]]].
* One episode of ''WesternAnimation/GodzillaTheSeries'' had HEAT visit a scientific station at Loch Ness to investigate reports of the Loch Ness monster attacking the station. The monster turns out to be all too real and on the rampage, and not even Zilla Jr. is able to drive her off for long. It turns out that the head scientist had captured Nessie's baby, and when he tries to escape with it Zilla Jr. and Nessie work together to capture him and free her child.
* In episode "The Egg" of ''WesternAnimation/WanderOverYonder'', Wander thinks a big, mean monster on a rampage is upset because its egg has fallen out of its nest. [[spoiler: The egg belongs to an entirely different species, and it is just a big, mean monster. The egg's ''actual'' mother, however, [[AlwaysABiggerFish is bigger, meaner]], and ''very'' grateful to Wander and Sylvia for helping its baby.]]
* In an episode of ''WesternAnimation/{{Witch}}'', the girls need to capture a young boar-looking animal who can turn invisible. Once they capture it and try to send it back to its own world, suddenly its [[MamaWolf very angry]] mother appears. She is less than happy about the girls touching her baby.
* In ''Literature/{{Franklin}} and the Green Knight'', Franklin and Snail find the "magic cherry tree" and then start getting pecked like crazy by a seemingly vicious warbler bird. It turns out that she's just protecting her eggs, though once Franklin and Snail state that they don't want her eggs, she becomes positively pleasant. The same is also true of Eagle beforehand, which Franklin equates with the monster from the Green Knight story and draws his paper sword as if to fight her. She tells him that she has no interest in fighting him, gives both him and Snail a ride, and later says she has to go because she needs to take care of her eaglets. This also happens with a bird dubbed the Wily Winged Beast in the stage show ''Franklin and the Adventures of the Noble Knights'', who is NotEvilJustMisunderstood and gets her own song about it titled "Misunderstood."
* Discussed in ''WesternAnimation/AmericanDad'', when Stan speculates that this may be going on with a recently killed bear, elaborating right up until the moment that he spots testicles. "There's no room for you in our stories!"
