* Tuck's mother in ''TheSagaOfTuck'', when [[spoiler:Tuck is in that ConvenientComa, scares everyone except possibly her husband]].
* In [[Literature/WhateleyUniverse Whateley Academy]] stories, during the Halloween invasion, we get at least two or three. Deathlist, a monstrous cyborg of superman-level power and the most horrifying villain in the Whatelyverse, makes the mistake of attacking the school and threatening the children. By the time Dean Carson (aka Lady Astarte) gets through with him, the only thing left of him to escape is his ''head.'' Jimmy T, a generally peacable shapeshifter, finds out his house of misfits, Hawthorne, is being raided by troopers looking to take "samples" from the helpless students, turns into fricking GODZILLA and stomps a mudhole in the forces there before then turning into a giant amoeba and ''eating'' an attacking dropship (though he did leave the soldiers in it alive, if [[EatenAlive mortally terrified]], in the end). All over the campus were mother hens ripping bad guys a new one....
** It is safe to say that Strega [[DisproportionateRetribution overreacts a bit]] when her daughter is kidnapped: she lays siege to Paris, destroying the headquarters of the group who are holding her, turning hundreds of tourists to glass and threatening to use a sonic weapon on them, and either beating up or [[CharmPerson subverting]] a half-dozen of Europe's most powerful superheroes.
* Hey, at least ''kiwi'' aren't that nasty. Right? [[http://asuka111.deviantart.com/art/Stealing-kiwi-s-eggs-109260278 Right?..]]
* Do not threaten ''Literature/StrangeLittleBand'''s Addison Harris's children. Not unless you are prepared for a world of pain anyway.
* Like the very many [[PapaWolf Papa Wolves]] on the [[WebSite/ThatGuyWithTheGlasses site]], Lindsay Ellis (WebVideo/TheNostalgiaChick) will crush you if you hurt her friends. Her character might hate children and would be willing to see the fictional ones die, but hurt an animal and you'll see some damn scary TranquilFury.
* ''Literature/ChakonaSpace'' gives us Chakats. It's programmed into their DNA. Seriously, ten fur-hating rioters vs. two Chakats in child-defense mode. The rioters felt outnumbered. And since they're {{Hermaphrodite}}s they can also qualify as PapaWolf.
* Soniqua, Sonic's and Mother Brain's daughter in SonicForHire, is this towards Sonic. Anyone who threatens or attacks Sonic will be mercilessly murdered by her.
* [[http://www.youtube.com/watch?v=EwrucT3Bz4c This lioness.]] "Don't you dare" indeed. A video by BBC Worldwide, "Hunting Lessons". Little cubs Lionas and sister Suki go out for a hunting lesson with their mother only to be faced with a [[http://en.wikipedia.org/wiki/African_buffalo#Attacks cape buffalo]] attack. Video taken from wildlife adaptation 'Pride'.
* A tad downplayed in the sense that Bunny would have gone overboard to protect them during the events of [[http://akaichounokoe.deviantart.com/art/Bunny-s-Maternal-Instinct-334237137 Bunny's Maternal Instinct]] but she would have indeed killed Madgie if she saw the absolute need to. However, she did give Madgie a hard slap in the end and had enough power in her that she not only outran the car that her sister was driving but stopped it without her sister slamming onto the brakes.
* The Creator/AnnaAkana short ''You Wouldn't Understand'' exaggerates this, when Anna becomes enraged at anyone who presents anything that could prove the least bit dangerous to her baby (eg, a pesticide-ridden lemon peel, a sharp plastic knife).
* In the Nation States (all welcome/chill thread) series, Julian Yamada points a rifle at a man who threatens to snipe her and her adopted son after she tells the boy to hide under the bed. However, violence is (fortunately) avoided when the man started to sympathize with her as an adopted parent, revealing that his daughter was adopted,too. They ended up making peace.
* The Blog/KnightsOfFandom is run by one of these. It's actually how they got started; she got so pissed off at seeing her "kids" on the receiving end of anonymous bullying that she organized a movement to counteract it.
