Papa Wolf / Fan Works

Anime and Manga

Ah! My Goddess

• From the fic Ah! Archfall!: you can do what you like to Jago, but you insult or threaten Lind, their unborn child or either of his Archs, and the very least he'll do is beat you senseless. And if you force him to summon Papa Jupiter to do it, he WILL kill you.

Attack on Titan

• Corporal Levi in My Child, to his and Mikasa's unborn child. In order to save the child from dying in childbirth, Levi makes a deal with the demon that has been hounding him the whole story to sell his soul for their safety. The baby is born healthy and safe, but Levi is dragged to hell to be tortured by the demon for all eternity in exchange. However, the knowledge that his son Rivahn is safe is the only thing that keeps him from regretting it.

Death Note

• In the Crack Fic A Charmed Life after learning that Shinigami can die, Light becomes one for Ryuk much to his Shinigami's amusement.
• In A Cure for Love Matt is one for V and Mello and Light is one for L:
  Matt: I know you're Kira or whatever... this is me impressed. Doesn't change the fact that if you start any funny business with her, I'll shoot you through the fucking wall. I'm quicker than you and your little Diary of Death. OK?
  [...]
  Light: It was you, wasn't it? You fucking tried to kill him!
  V: I'm sorry, Light.
  Light: Not going to cut it, V. I thought that you didn't want to kill L.
  V: I don't.
  Light: If you touch him, I'll kill you. I'll kill all of you.
• Light/Kira becomes this for L and the Wammy's Kids in the Death Note fic I Won't Say:
  Light: I will also keep the Death Note where I can reach it whenever I need to, because I will need that power to protect you and our orphans. But... would you, and could you, perhaps, consider... combining Kira and L's powers?
  L: What, as in, 'Quit killing, or I'll set Kira on you'?
  Light: Yeah, pretty much like that.

Dragon Ball

• In one of the strangest bits of this trope ever, Vegeta shows this in Dragon Ball Z Abridged after Cell kills Trunks. He ends up roaring "MY BABY BOY!" and tries to murder Cell right there. Too bad Cell's way stronger than before.

Fullmetal Alchemist (2003)

• The most common idea for parental Roy/Ed fanfics. For example...
  • In A Single Spark, Roy delivers a verbal and physical beat down to Elias, a serial killer of the author’s creation, for kidnapping Edward and insulting him. When Elias shoots Ed, Roy takes a bullet for him.
  • Roy becomes a near literal Papa Wolf when he is transmuted into a human/dog chimera and adopts Ed as his “cub” in Distorting Equivalency .
  • Roy undergoes Cold-Blooded Torture to protect Ed in Save Me.
• Roy has his Papa Wolf moments with Al, too.
  • In Nothing Ventured, Roy adopts 12-year-old Al and 13-year-old Ed from an Orphanage of Fear as his sons. When a man kidnaps them asking for ransom, Roy brings his entire team to rescue his boys. When the man threatens Alphonse with a knife, Roy sets his arm on fire.
  • In Not Just A Suit of Armor, Roy takes a bullet for Al even though Al is just a soul bonded to a suit of armor and thus can’t die just because Roy couldn’t stand to see him get hurt.

JoJo's Bizarre Adventure

• In chapter 10 of the chatfic Joestar Family Groupchat Shenanigans, it's revealed that when Dio found out his son Giorno was being abused by his stepfather, Dio's first course of action was to show up at their house and beat the stepfather up.
  DIO: no one gets to mistreat MY son. So I felt beating that stale excuse for a man half to death was only a fitting punishment. Taste of his own fucking medicine.
• Pieces: Even without a Stand in this universe, Bruno will do anything to protect his adopted children, including using his connections to order a hit on the university professor that molested Fugo.

My Hero Academia

• Conversations with a Cryptid:
  • All For One, in his own villainous, murderous way—as the villains that kidnapped Izuku found out to their detriment. He also previously had the children who bullied his child disappeared and experimented on beyond recognition. And he has plans for Bakugou...
  • After All For One escapes from the prison and believing he was going to harm Izuku, All Might is ready and raring to confront the latter, even if it meant his possible death, all so he could buy some time for Izuku to escape.
• In Forgiveness is the Attribute of the Strong: All Might is very protective of all his adopted kids.
• Custody Battle: All Might goes berserk when Izuku is in danger.
• In Fear No Evil, All Might, All for One, and Aizawa form a Papa Wolf team in response to Izuku's kidnapping by Humarise.
• A common theme in many MHA fics is Aizawa being a father figure toward Class 1-A (often called "Dadzawa"), including being ferociously protective of them, willing to take on top-tier villains (or abusive/neglectful parents) who dare try to harm any of "his" kids, not hesitating to kill or to die in order to protect them. Similar is "Dad Might" and his protection of Izuku.
• In the series The Aizawa-Yamada Family, both Aizawa and Present Mic are fiercely protective of Shinso, who they foster and then adopt. Mic screams at his mom and sister to leave because his mom is Jerkass Abusive Parent who muzzled him as a kid and his sister thought it was okay. Now they're still jerks who insult and criticize everyone including Hitoshi and ultimately try to grab him after he gets fed up and uses his quirk to protect his dads. Later, Shouta and Hitoshi encounter a badly abusive former foster dad. Shouta snarls that he'll break something if the guy touches his son and ultimately punches him. Hizashi notes Shouta held back as he's more than willing to pummel anyone who threatens his boy.
• Look Away All Might goes undercover as a quirkless guy to find kidnapped Izuku. When he dispenses with the ruse and grabs Izuku, he roars "IF YOU EVER COME NEAR MY BOY AGAIN YOUR LIFE IS MINE!!"
• Aizawa doesn't hesitate to give Endeavor a "get your filthy hands off my student Enji" in Hot to the Touch when Endeavor is being his usual self berating and attacking Shouto, his own son.

Naruto

• Orochimaru, of all people, is one in A Father's Wrath. In this story, he is Naruto's father instead of Minato. On the lighter side, he cares deeply for his son, and his actions - including joining Akatsuki and forming the Sound Village - are all to protect him; he has found a source of redemption. But threatening Naruto is the fastest way for him to remind you that he wasn't called The Snake Sannin for nothing. Just ask Hidan.
• Naruto in Win Some, Lose Some, a collection of one-shots. Naruto's warning when Kurenai, Hanabi, Ebisu, and Konohamaru find out about his (adoptive) daughter basically amounts to "If you tell anyone about my daughter, I'll kill you. If anyone tries to harm her, I'll kill them. If anyone kills her, I'll burn Konoha to the ground." Turned up to eleven because the Nanabi is sealed within her, meaning the Kyuubi is protecting her too.
• Daiki from Destiny is a Hazy Thing is this for Naruto. One scene has him tampering with Naruto's seal to allow him, Naruto, and the Kyuubi to talk with his real parents. He promptly spends several minutes slowly brutalizing Minato's soul.
• Naru-Hina Chronicles: In Chapter 131, the temporarily resurrected Minato meets the Konoha elders and angrily demands to have answers over the way his son was treated while he was dead.
• Son of the Sannin:
  • Jiraiya hits this in full force during Chapter 79. He's more than ready to unleash his wrath on Danzo for placing Naruto in danger of being captured by Akatsuki, as well as putting his biological son Hagane into a coma in their latest mission.
  • In the same chapter, Shisui Uchiha already had many personal reasons to hate Danzo, but the last straw that made him decide to kill the bastard was that he sent his minions to kidnap his children.

Neon Genesis Evangelion

• A Crown of Stars: While Shinji is saying he does not believe he can forgive his abusive father, he is told that in timelines where his mother Yui did not die, Gendo is an actually scarily overprotective father.
• The Child of Love:
  • Kaji tried –and almost managed- to destroy SEELE to talk Gendo into giving up his plans and so protecting his former ward Asuka and her daughter.
  • Subverted with Shinji. He tries to be this but he often panics or loses his nerve and other characters have to help him to man up.
    Misato:"You're supposed to be a man now. ACT like a man! Come with me, NOW!"
• HERZ: Shinji hates killing… but threatens his wife or his daughter and he WILL do whatever it takes to protect them.
• Neon Genesis Evangelion: Genocide: Nakajima's father plots against and eventually assassinates Keel Lorenz in order to protect his son.
• Rise of the Minisukas: When Kaji arrives to his regular bar in T-3 to get loaded and discovers that 1) the Noir Minisuka likes to drink (seltzer) here and 2) there are patrons that try to hit on her (regardless of the fact she is eight inches tall), Kaji tells the bartender who told her this latter tidbit that the Minisukas are thirteen years old, he considers Asuka a daughter, and the bartender better tell him the names of everybody who tried to hit on her so he will make sure they get sent to the worst bases NERV has. The bartender does so.
• The Second Try: Shinji, like his wife Asuka, is very protective of his post-Third-Impact family, though he keeps his cool better than Asuka...most of the time. Anyway hurt her or their daughter Aki... And. You. Will. Die. You'll not even see it coming. The MP-Evas learnt this the hard way.

One Piece

• Muzzled shows a moment where Zoro literally resorts to biting Marines (after having his swords taken away and his hands tied) who tried to separate him and the kidnapped Usopp and Nami to trap Luffy. Even more awesome than it sounds given his fighting style. His bites break bones.
• This Bites! shows this in spades during the SBS broadcast on Omatsuri Island where no few amount of viewers are forced to listen to their friends and families break down and be devoured by Lily-Carnation. Some of the reactions are as follows.

  Captain Dugongs: FIND ME THAT GODS-BE-DAMMED ISLAND... SO I CAN RIP HIS F—-ING B—TERD'S SKULL OUT THE BACK OF HIS HEAD AND CRUSH IT WITH MY OWN BARE FLIPPERS!!!
  Whitebeard: I may not be able to sink that island from here...But I am very tempted to try.
  Ace: Because this broadcast is the only thing keeping me from... BURN[ING] THAT F—-ING ISLAND TO ASH... THAT'S IT! HE DIES NOW!
  Garp: How dare you do this to my grandson... Buster Call? No... that's too hands-off. We can destroy that island after I've ripped that monster apart WITH MY OWN TWO HANDS!
  Dragon: I know you won't lose Luffy...but if you don't kill that monster for this, then I will.

  • Luffy doesn't give a flying rat's ass if you are a god, just try to glare at his crew and you can choose your grave's emplacement. Hell, he even stands up to his grandpa because the guy showed hostility towards his friends.

Pokémon

• Silver, from Pokémon: The Great Adventure. The man is mercilessly protective of Ash in particular and doesn't think twice before jumping at Mewtwo's throat for petrifying him. As the Legendaries say: "It's safer to attack a baby Kangaskhan in his mother's pouch than a kid Silver took under his wings". Did we mention he is a very old Ancient and an Ice Aura Master?
• Meyer, as per canon, is this in Pokémon Reset Bloodlines. When Belmondo kidnapped Clemont right from his bedroom, Meyer confronted him as the Blaziken Mask and broke the guy's arm, warning him not to try something like that ever again.
• A Professor and a Student: Kukui verbally tears into his colleagues for abusing Ash's kindness when they essentially interrogate Ash about information the Pokemon League has deemed classified about himself.
• Lance in Traveler and Traveler Recollections is quite protective of his apprentice Ash. Lance is easily the closest thing to a father Ash has and is willing to train Ash so he can reach his true potential, gives him gifts when he earns them after impressing him, and always bets in his favor whenever Ash is going against a strong opponent. Lance has also tried to sacrifice himself in order to keep Ash safe from Mewtwo, threatened Mewtwo when he discovered that the creature could possess Ash after leaving a piece of itself inside the boy, and made a promise to himself that he would make it so Ash would never be taken over by an elemental Concept like a past chosen of Articuno, Haukea.

Pretty Cure

• Anything for Family: Rosemary and especially Joker are motivated to join the rescue mission due to their daughters, Chiho and Maimiko respectively, being kidnapped by the Big Bad. Rosemary (as Cure Fragrance) primarily leads his team in the right direction, while Joker is the one to deliver the killing blow to the kidnapper via Soul Eating.
• in Hatch Ya Later Mepple panics when Kabaton steals his egg but beats up Kabaton when he throws the egg.

Rurouni Kenshin

• Light of the Snow Red Village is an AU fanfic that answers the question, what if Kenshin and Tomoe had a child? After Tomoe is killed much later in the timeline due to treachery from his superiors, Kenshin takes to wandering with his daughter Hikari. Throughout the story Kenshin is fiercely protective of her well-being and happiness, even going so far as barring her from learning kenjutsu (he later allows it, after it's pointed out by another character that it's hypocritical of him while he carries a sword himself). Following some adventures they eventually end up in Tokyo at the Kamiya Dojo, where the manga timeline begins. Currently incomplete, but it's a great story nonetheless.

Spy X Family

• In these two, fan animated, comics (the first in Spanish) Anya has been kidnapped by the lead scientist who performed the experiments on her before she ran away and ended up in an orphanage before Twilight, posing as Loid Forger, adopted her. Although it's not shown, it's evident that both Twilight and Thorn Princess, aka: Yor Forger, left a trail of dead security personnel and accomplice scientists in their mission to get their daughter back.

Comic Books

Batman

• Pretty much every fanfic that has Batman/Bruce Wayne adopting a child has at least one instance where the child gets in trouble and Batman will come to the child's rescue.

The DCU

• The Unfantastic Adventures of Bizarro No. 1: What does it take for Bizarro to stop fooling around and come up with a plan to fight off the Blue-Kryptonite Men invasion? Realizing the Blue-K Men killing them all would kind of spoil his son's Father's Day.
• In "Mercy", Hades of all people demonstrates this. While he released Circe from the Underworld to taunt Hippolyta, he is outraged when he learns that Circe's actions nearly led to Diana's death and makes it clear that he will take great pleasure in renewing Circe's punishment.

Sleepwalker

• Sleepwalker is deeply torn by angst and loneliness over his being exiled from his home dimension of the Mindscape and trapped in Rick Sheridan's mind. He doesn't have any doubt at all about one thing, though. If you threaten Rick Sheridan or any of Sleepwalker's other close human friends, you are in for a world of hurt.

Crossovers

Adopted Displaced — My Little Pony: Friendship Is Magic Mega Crossover

• All of the adoptive fathers and honorary uncles (and other males in the new families) are highly protective of their adoptive Equestrian children, even after they've shown they've become strong enough to take care of themselves. Special mention goes to the RED team, who are all perfectly willing to doom Equestria all because Fluttershy didn't want to go back without them and Celestia was going to kidnap her.

The Bridge — My Little Pony: Friendship Is Magic/Kaiju Films Mega Crossover

• Godzilla Junior becomes the mentor to a filly named Chibi Moon who has a lot of potential as a unicorn but lacks control until he became her sensei. When a brainwashed Starlight Glimmer is shown to have kidnapped and locked up Chibi Moon, Godzilla Junior flies into such a warpath he overpowers Starlight's cutie mark removal spell and Nightmare's attempt at possession by sheer willpower alone.

Child of the Storm — Harry Potter Mega Crossover

• Thor, who is intent on making up for lost time, and if anyone threatens his son, he will demonstrate just what it means to be a Physical God. While Harry unfortunately has a knack for finding the nearest route between his nose and trouble, his father is usually not far behind and armed with an indestructible hammer, planet-busting strength, and the raw might of the God of Thunder.
• Odin. He may have made mistakes, but holy crap, you do not want to be in Thanos' shoes when the Allfather catches up to him, not after what happened to Loki (Loki went nuts of his own accord, but Thanos broke him to his service). For direct examples, see what he does to Chthon, an Elder God (and thus theoretically out of even his weight class), the Red Room (kidnap my grandson? Cue The Scourge of God), and threatens to do to the Council Elite of Skyfathers (each a Top God) when they consider binding or killing Harry because of the threat he potentially represents as the Dark Phoenix.
• The Avengers in general are this to Harry and other associated children, even after they become more than capable of looking after himself. The responses tend to be violent, creative, and deadly precise.
• Albus Dumbledore is this to his students. Hurt one of them and you will find out why this man is considered the most powerful wanded wizard on the planet and feels comfortable dropping extremely politely worded fuck-you's to the Merlin of the White Council.
• Magneto. He loves his children, and while he has at least nominally reformed, he is an Omega Class mutant and everyone with a brain is absolutely terrified of him, and for damn good reason.
  • He also extends this attitude to Harry, who he regards as a kind of adjunct grandchild on the grounds that his daughter Wanda is Harry's godmother, would have taken him in and raised him as her own if circumstances had been different, and is currently the closest thing Harry has to a mother. Certainly, he name-checks what the Red Room had done to Harry as well as what they had done to Lorna as his motivation for unleashing hell on them.
  • He further extends it to Harry Dresden, Wanda's apprentice and boyfriend/his potential son-in-law, as Quintus Cassius found out the hard way.
• We don't know much about Stephen Strange, prior to his Origins Episode in chapter 20 of Ghosts of the Past. What we do know is that even the most powerful Gods step lightly around him and that he is a Friend to All Children, especially those caught up in his schemes.
  • For instance, when having an otherwise Friendly Enemy style chat with Nimue, he adds that he is very fond of Carol (who Nimue had just turned into a tree) if anything she has done to Carol is permanent, he will make her a living demonstration of just why he is so feared. While the antagonist in question is otherwise pretty blase and willing to provoke him, that makes her hesitate.
  • One oft-cited example is what happened when the White Council decided a 13-year-old Wanda Maximoff was too dangerous to live, and were perfectly willing (and able) to go through Magneto, Xavier, Dumbledore, and Howard Stark to do it. Strange turned up and essentially challenged them to a duel. All of them. The White Council is the literal 1% of the strongest wandless practitioners on Earth. Even one of their very strongest can take on Physical Gods. They number in the thousands. They thought long and hard and backed the hell down.
  • He also arranges the destruction of the Red Room, despite the fact that they are hidden from his sight by Sinister, someone he's spent centuries hunting... all to avenge a child. Or rather, two. Specifically, Harry and Maddie. He nearly kills himself doing it, driving himself half mad, but he wreaks utter devastation. And when he does catch up to Sinister, the man almost shits himself - and with good reason.
• When Coulson recruits Harry Dresden to track down the veidrdraugar and their Master, Dresden is reluctant because he knows very well that he's stupidly far out of his depth. Then he finds out that they killed children. A few chapters later, Gravemoss utterly dismisses Dresden and rips out Sif's heart with his bare hand. Dresden responds by unleashing his Death Curse. This is under Paris. A few moments later, a vast column of fire about a thousand feet high erupts over the Paris skyline and Gravemoss lands in the North Sea, somewhere off the east coast of Britain. Unsurprisingly, Gravemoss is terrified of Dresden.
• Even Lucius Malfoy counts. He is as evil as they come, a fully-fledged Magnificent Bastard who has a somewhat Dalek-like attitude to muggles (though he considers torturing them to be beneath him) and murdered Harry's maternal grandparents in cold blood. But as Baron Von Strucker found out, threatening his wife and son is the last thing you will ever do.

Dante's Night at Freddy's — Devil May Cry/Five Nights at Freddy's Crossover

• Do not mess with Dante's children. He will gouge a carousel out of the ground and drop it on you if he can't find anything bigger.

The Death God Alliance — Percy Jackson and the Olympians/The Kane Chronicles Crossover

• Hades' very measured and restrained reaction to his son Nico's disappearance - which involves damning evidence against the House of Life - is declaring war against the magicians. Oh, and he also enlists his brothers Zeus and Poseidon's help to ensure the war would be a one-sided slaughter. Poseidon also has shades of this, agreeing to help Hades in part because he had a history of Egyptians causing misfortunes to his children.

Equestria Girls: Friendship Souls — My Little Pony: Equestria Girls/Bleach crossover

• Torch is unafraid of sending Ember out into the field of battle because he trusts her ability to fight and survive. Do something that threatens her otherwise, like say capturing her, and he will bring down the full wrath of his horde on your head.
• The Lament is already a somewhat unstable guy, but the fastest way to get on his shit-list is to harm the Hollow children he calls his own. According to Twilight Velvet, he was still this even when he was still Hard Nail.

Harry Potter And The Invincible Technomage — Harry Potter/Iron Man Crossover

• Tony Stark becomes this to his adopted son Harry. It is also demonstrated that many of the heroes feel this way toward their allies' children.
• Thor gets a Moment of Awesome (that doubles as a Funny Moment) when the Ministry of Magic tries to take Harry away from Tony: Thor breaks in and calmly warns the Wizengamot that voting for taking Harry away would cause Thor to tear down the building and break every single bone of every member of the Ministry. Harry then gets him to amend it into only tearing down the building and breaking the bones of everyone who voted yes (the rest of the Ministry people are innocent, and the Aurors that would try and fail to stop him are merely doing their job). The Wizengamot promptly vote to leave Harry with Tony.

Hunting Series — Supernatural/The Matrix Crossover

• John Winchester in part three Hunting and Saving. He kills three vampires to save a little boy called Tom Anderson, thinking that he'd never be able to live with himself if he let the vamps live to kill more kids. That if he did it'd be like watching them kill Dean and Sam while he watched and he'd never let that happen.

Imaginary Seas — The Camp Half-Blood Series/Fate/Grand Order crossover

• The normally serene and caring Chiron gives his Lostbelt counterpart a Death Glare after the latter writes off Percy, Chiron's prize student, as a "waste of time".

Justice League of the Rebellion — Code Geass/DC Comics crossover

• Mister Miracle, alongside Big Barda, have become the adopted parents of Lelouch and Nunnally, and both are greatly protective of them. When he fears that Lelouch's hunger for vengeance will consume him, Scott takes matters into his own hands by teleporting Britannia to assassinate Charles zi Britannia, while also killing him in revenge for abandoning his children.

The Last Connor — Terminator/Alien crossover

• Pops and Hicks act as this to Newt.

A Man of Iron — A Song of Ice and Fire/Iron Man Crossover

• Tony decides to become this for Jon Snow, as someone has to take care of the kid and Ned simply doesn't do enough for his cousin's standards. Do not think he's unable to get serious when it's important: he outright verbally demolished Catelyn Stark when she threw a hurtful comment towards Jon and called Ned out on his shortcomings as a father doing nothing to protect his son from his wife. Though he thinks of himself as being Jon's uncle rather than his father.

Neither a Bird nor a Plane, it's Deku! — My Hero Academia/DC Comics Fusion Fic

• Despite his initial reservations about adopting Izuku, Hisashi Midoriya proves to be this, fiercely defending Izuku from Detective Shitsugen when the latter said that someone should get punished for Katsuki's grievous injuries. As Firestorm, he's even more protective of Izuku, threatening to turn all of Mt. Fuji into a pillar of salt if it meant killing the Ultra-Humanite after the Villain seemingly blasted Izuku to his death. His sheer fury was enough to give even All Might pause.
  • All Might, who took Izuku under his wing, isn't lagging behind either. When the above-mentioned event with the Ultra-Humanite happened he was sorely pissed, but when the USJ Arc happens Izuku finally meets a threat that is capable of hurting him (the Noumu) and what All Might does when he finally arrives and sees Izuku beaten to an inch of his life and a nanosecond away from getting his spine snapped in half à la Bane is to tear the Noumu to pieces and attack Tomura Shigaraki in such a brutal fashion that only the timely support of his fellow Villains prevented him from dying right then and there.

Perturabo in Remnant — Warhammer 40,000/RWBY Crossover

• Perturabo made Penny Polendina and regards her as nothing less than his own daughter and loves her very dearly. Like any good father, he reacts poorly to anyone that means her harm and will not care who they are. At one point, Leman Russ demands to face her in a trial by combat to see whether or not she's a soulless machine that the Imperium has been instructed to destroy any vestige of. If Russ decides that she is a threat to the Imperium, then he makes it clear that he will do his duty to ensure that doesn't happen. Perturabo was ready to kill his fellow Primarch and damn the consequences if he hadn't been talked down by Glynda, Winter and Cinder.
  • The same goes for Ren and Nora, whom he adopted after saving them from a Grimm attack on their village. When they are killed during the Siege of Terra, he takes a brief moment to say his final farewells, and then proceeds to rain down ten different kinds of hell on whatever Traitor forces he sees. Needless to say, they didn't stand a chance.

Remnant Moonview — Five Nights at Freddy's/ Young Justice (2010) Crossover

• Uncle Henry to Michael. He makes it clear he does not want reporters or anyone else harassing Michael while he’s recovering in the hospital and is pissed when he realizes Michael’s father was, at best, neglecting his son and at worst.

Rise Of The Gale Forces — The Incredibles/Portal/Jurassic Park/Megamind/Donkey Kong Country/many other media Crossover

• Both Mr. Squall, Mr. Parr, and Chomper the Tyrannosaurus rex. Subverted and later inverted for Chomper's case, though, when his protectiveness of his fellow rexes costs him his eye - but also makes his own children angry enough to horribly slaughter the Big Bad.

Say It Thrice — Beetlejuice/Danny Phantom Crossover

• Betelgeuse is this for Lydia. Following the events of the movie, he - regretting certain past actions - effectively adopts her as his protectorate, and by the time of the fic they are Like Brother and Sister. He calls her "my girl" and has a tendency to go ballistic if anyone even thinks about hurting her.

Spider-Ninja — Teenage Mutant Ninja Turtles/Spider-Man Crossover

• In the chapter "Shred Of Green", Shredder, once the Foot Clan begin losing their fight with the Hamato Clan, tries to kill Leonardo. Splinter knocks his sword from his hand with a kunai, then gives Shredder such a beat down that Nick Fury is impressed.
  Splinter: You will not harm my son, Saki!

Ultimate Re-Imaginings — Marvel Universe Mega Crossover

• Clint is this towards Joey as he once nearly killed the boy's actual father for putting him in the hospital and breaking his arm when Joey was twelve.

What Was Created By God — Percy Jackson and the Olympians/Fate/Grand Order

• No matter his iteration, Poseidon is extremely protective of his demigod son Percy.
  • When the boy gets stranded in the Atlantis Lostbelt and desperately prays his divine father to send him help, the Lostbelt variant of Poseidon sends a giant sea monster in order to bring him to Atlantis.
  • The Riordanverse variant outright reaches beyond his origin timeline when Percy is captured and about to be forcibly put on stasis, allowing the boy to regain his full power to escape and potentially unraveling his Lostbelt counterpart's brainwashing to ensure Percy will have an ally.

Wonderful (Mazinja) — Worm/The Wonderful 101 Crossover

• Danny is this to his daughter Taylor. When a psychopathic mass murderer threatened her, Danny tackled him.

With Pearl and Ruby Glowing — Children's Media Mega Crossover

• Dr Flug doesn't fight back when Black Hat beats and rapes him, but on finding out Black Hat molested 5.0.5. (here Flug's human son, named Oso), Flug douses Black Hat in gasoline and lights him on fire.
• Mr Bigg is this towards FruFru and her own daughter Nadine, and becomes an honorary Papa Wolf to DW (who was kidnapped by the same man who murdered Nadine) and Muffy (who saved DW), willing to do deadly favours for their families when things go From Bad to Worse.
• Sulley is this to Boo, who he adopts when he finds her escaping from her abusive stepfather.
• Mr Yut, when he finds his sons Milo and Oscar were threatened with a gun by the resource officer over some hijinks with a unicycle, screams threats and obscenities at the officer and the principal, and, when forced to make a public apology, is incredibly sarcastic throughout.

Crossovers Without Separate Pages

• Jack Kenway in "Harry Potter and the Grand Trainer Tournament" towards his adopted daughter Jasmine. When she was seven her parents were killed during a rally protesting Kanto basically ruling over Johto. That night Jack asks Jasmine what she wants and she says she wants Kanto to hurt. Jack proceeds to declare war on Kanto, ending with his discovering a lost Pokemon Art and blowing up the Kanto Pokemon League. To repeat... he started and won a civil war because the daughter he'd just adopted was crying. No one messes with Jack's little girl.
  • Remus has become this for Harry. When Lockhart tries to take a picture with Harry and wraps his arm around him Remus throws him to the ground and makes it VERY clear that no one touches his adopted son.
• In the RWBY/Marvel Cinematic Universe Fusion Fic In Shades of Red and Gold, Tony becomes this to his daughters Ruby and Yang, giving a "The Reason You Suck" Speech to Christine Everhart after she asks if he feels guilty that he's raising them using money from weapons development, and his primary motivation for creating the first suit is to escape so he can see them again.
• In the RP fanfiction by Cheyenne89 Pictures, Into the Unknown 3, Kirby of all people does the inversion of this trope after finding out his own first mother was sent to the Lake of Fire, and he transforms into his own beast form and gets into a huge battle with Mr. Brick, the main antagonist. And this was Kirby's most unsettling line in the fanfic:
  Kirby: (after being turned into his own frozen heart beast) …You will be wailing, and gnashing your teeth forever like what you did to my mom!
• In A Child Avenged Harry reacts very poorly to Director Fury kidnapping his five-year-old godson Teddy to try to threaten him into joining the Avengers Initiative.
  Harry: I'm leaving, but know this: If Teddy transforms this month because of your careless actions, you will face the consequences, and if you ever even think of touching him again, I will paint the world red with the blood of your Agents, and I'll leave you to fucking watch, Fury.
• In Alias Mars, Keith Mars (Veronica Mars) and Jack Bristow (Alias) each make it clear that they’re willing to do anything for their daughters, up to Keith trying to threaten Jack when he thinks Jack may have abducted Veronica to Jack making it clear to Don Lamb that at least part of the reason he doesn’t like Lamb is that Lamb’s actions endangered Sydney’s life (although Jack’s reference to his disgust at the way Lamb treated Veronica’s rape accusations shows that his ‘papa wolf’ instincts don’t completely stop at Sydney).
• In From Fire, Professor Xavier feels his new pupil Harry's psychic distress and goes to help. When he finds Lord Voldemort determined to destroy the boy's mind, he becomes quite upset and engages in a psychic brawl with the Dark Lord while protecting Harry's mind from the fallout.
• In Helluva Wizard, Moxxie manages to Kill Valentino because he dared to kidnap and attack Harry, his adopted son. Granted, Harry dealt most of the damage and Moxxie just delivered the killing blow, but still, it's an impressive feat nonetheless. He's on the warpath in general during this arc, along with his wife and the rest of Harry's family and friends.
  • James Potter is perfectly willing to join the Exorcists along with his wife and to storm Hell itself solely to "rescue" Harry and destroy the Dursleys.
• Alex Mercer in Wolf in Sheep's Clothing literally created the Faunus race and thinks of them as his masterpiece, to the point of considering all of them his children. After returning to find they had been enslaved and oppressed by humans, Alex was so pissed off that he personally led the (very swift) revolution that won the Faunus their rights. And when attending Beacon as part of a deal with Ozpin, he threw Cardin through a window with enough force to create a visible shockwave after catching him bullying Velvet.
• Both a biological and adoptive version occur in The Dragon and the Butterfly. When Stoick finds Hiccup seemingly injured and at the mercy of users of dangerous black magic, he bristles with anger and orders an attack to get his son back.

Unfortunately, he gets fatally stabbed in the process.

Kung Fu Panda

• The Vow (an Alternate Universe Fic of Lord Shen's life) provides several examples.
  • Shen's father Lord Goa is a fair and calm ruler, but should his son or honored guest Lady Lianne put into immediate danger, he can be as ruthless as his son. After Shen is banished from Gongmen for his crimes and Lianne is demanded to return to her distant father Lord Chang who would continue pressuring her into marriage (with her having a broken heart due to her beloved Shen's actions), Goa prevents Chang from harassing Lianne for the rest ten years of his life.
  • There's also the canonical version of Po's father.
  • Lianne has believed for a long time that her father cares nothing for her safety, else he wouldn't have tried to marry her off so emphatically or sent her to live with strangers for a year after an argument about the quality of suitors he foisted onto her. However, when she returns to her birth home after three decades of absence, her uncle Hong reveals that when Chang heard about Shen's return and the subsequent imprisonment of Lianne, he wanted to do everything needed — like calling upon every favour he owed, summoning every general and friend or even seeking an audience with the Emperor himself — to raise an army and storm Gongmen City in order to rescue her. The only reason he didn't do this was because he suffered a stroke in his stress.
  • In the epilogue, Shen himself becomes this after he warms up to his and Lianne's son Zian, being as determined as Lianne to keep him safe.

Megamind

• In the AU fic Knocked Up, Megamind saves a pregnant Roxanne from an extremist group intending to do their unborn child harm. And then, after the baby is born...

Rise of the Guardians

• While it was established in the prequel books that Pitch was a Papa Wolf, the story Guardian of Light takes it up to eleven. While he starts out as an evil version of this trope early on, it eventually gets to the stage where he jumps off a cliff just to save his daughter, Helen.
  • Helen's adoptive father is no slouch, either, and when Helen is taken by Pitch he joins up with his ex-wife in order to rescue her. Even better, his name is Lowell, which means 'little wolf'.

Film — Live Action

Marvel Cinematic Universe

• Avengers fanfiction has a ton of examples where Hulk gets mighty protective over Clint/Hawkeye, but none more so than Big Green Guardian Angel. The biggest scene in the one-shot was when Clint, after accidentally exposing the scars on his torso, explains that he got them as a kid, causing Banner to Hulk out right then and there. As if that wasn't "aww" eliciting enough, Hulk stopped his rampage enough to trace Clint's scars, whimper a little, and proceed to destroy everything in sight as a result of his rage.
• Hawkeye becomes this to a de-aged agent Coulson in this story.
  • Note that this story is an inversion of the Fandom-Specific Plot in Avengers fanfic where all the Avengers get de-aged and Coulson has to babysit them. Such stories usually depict Coulson as the Papa Wolf Team Dad.
• Loki, of all people, becomes this to his adopted daughter in the fic Mischief, Lies, and Other Hazards of Parenting and its sequel, Thor's Days. In the first he practically bolts to the park where she's having her birthday party when he thinks its being attacked by Dr. Doom (it wasn't), and in the second he almost snaps her scout leader's neck when she's injured due to said scout leader's incompetence (Tony intervened that time). And then in one chapter, Natasha comes to him and makes a hint that Clint might go near the girl. Loki's response is scary.
  Loki: I will, however, show no mercy to anyone, and by anyone I mean your dear Agent Barton, who chooses to strike at me through her.
  Natasha: So if Clint takes Kara, you'll kill him?
  Loki: Has my dear brother ever told you how he and I would sneak into the orchards of the goddess Idunn when we were children? Those apples, which I was so very good at stealing, grant whoever eats them a very long, very resilient life. If your little friend does anything to Kara, I will find a way into Asgard and strip Idunn's orchard bare. I'll cram them down his throat and save enough for you, so you can watch as I torture him for eternity. No matter how much either of you beg me to kill him, he'll live through every length of gut ripped through his flesh, every severed limb, and every drop of acid spilling into his eye. Now is my meaning clear?
• In father/son Tony Stark and Peter Parker fics, it’s common to write Tony as a Papa Wolf for Peter. Some examples...
  • In Buckets-Of-Stars’s AU series, Tony adopted Peter when he was a little boy. He lets his Papa Wolf side show in A Major Party Foul, Inconcieved When It Definitely Shouldn’t Be, and The Face In The Papers.

Back to the Future

• In Back to the Future Prequel, Marty is kidnapped by a vengeful enemy of Doc's, who throws him into an icy lake to drown. Doc subdues the physically bigger enemy and swims two hundred feet to save Marty.
• In an alternate take of Marty’s showdown with Buford Tannen, Doc fights off his captors to help Marty after he’s been shot for real in the fanfic High Noon at Eight.

Godzilla

• Abraxas (Hrodvitnon):
  • It's hinted that Thor feels quite paternal towards the Vivienne Graham half of Monster X from the moment he's awoken by Monster X's call. There's a reason for this.
  • Godzilla has also shown hints of this towards Monster X, such as comforting them and even letting them sleep near his vulnerable gills.
  • Darkly exploited by the Many in one particular Nightmare Fuel scene where they're hunting and assimilating new victims, using the voice of a lost and dazed father's missing son to lure him in.

Omen IV: The Awakening

• Always Visible: It is Delia's father who is responsible for the character named Jo ultimately dying.

It (2017)

The League of Extraordinary Gentlemen

• Skinner, Nemo, and Jekyll all have a tendency in this direction in The Private Diary of Elizabeth Quatermain. Jekyll has (eventually) his adopted son, Nemo has his foster daughter, and Skinner has his niece.

Star Wars

• Qui Gon Jinn gets into an Unstoppable Rage twice in The Marionettes Dance trying to protect his unconscious apprentice Obi Wan. The first time, he slices various limbs off four guards after having used a Jedi Mind Trick to fool them into ignoring his lightsaber. Later, he's really set off when they lie and say Obi-Wan died. He crushes one guard's throat but doesn't kill him, then does kill two more with his bare hands. The first guy gets a piece of nasal septum driven into his brain by Qui-Gon's elbow and the second guy gets his neck snapped after Qui Gon choke-holds him (no Force involved) and forces him to admit that Obi-Wan is still alive and where he's at. He may have felt he had no choice but to kill that one, he was wielding a box that controlled shock collars that both Jedi had been forced into wearing, and the Electric Torture was really ticking off Qui Gon already.
• Gladiatorial Jedi ends in this plus Mama Bear. Luke was forced into a Gladiator Games plot with threats to kill Mara and Ben if he didn't comply. But when he refuses the romantic advances of Callista, who's running the whole thing, she has Ben kidnapped and put in the arena. Really bad idea, as Luke is immediately on the attack as soon as he's freed from his cell. The guy who's sent to give Luke his lightsaber realizes very fast why he was told to hand over the saber, tell Luke what was going on, and get the heck out of the way. Luke gets help from an ally who befriended him during his ordeal but isn't afraid to battle a large predatory creature to save his son. And then Mama Bear Mara shows up to add to it.
• Uncle/niece version with Luke and Jaina in The Love of An Uncle And Niece: Luke And Jaina One Shots. Luke basically loves her like the daughter he never had, as many of them take place before his own son, Ben is born. The biggest one has Luke charging into a group of sleazy reporters and igniting his lightsaber to force them to back off a humiliated Jaina, who was victimized at prom by a cruel group of popular kids. Of course, Han is ready to kill someone too when he finds out about it.
• In the AU fic A Call For Help, Luke and the other rebels are captured by imperials and tortured shortly after a version of Bespin where Han wasn't carbon frozen. Luke, not thinking clearly, calls to his father through the Force. Cue an enraged Vader storming the place a few minutes later and unleashing on the guards, even killing someone else's son in retaliation. He yells that he wanted the rebels alive but UNHARMED. Despite Luke again refusing to join, he even gives an hour head start of escape before the hunt resumes.
• Obi-Wan in You Found Me, when he cuts off the arm of a bar patron that was beating up a very drunk Anakin
• In the Star Wars: Lineage, series Troon Palo is very protective of the Initiates he looks after. One story is set after Qui-Gon promised to take Obi-Wan as a Padawan but was called away for longer than expected due to a mission, leaving Obi-Wan distraught when it takes far, far longer than "several weeks." Palo mentally promises that the moment Qui-Gon gets back, he's going to throttle the man with his own tabards and then put him in a headlock.
  • As for Qui-Gon, anyone who tries to mess with Obi-Wan will be met with extreme prejudice. And you do not want to be on the wrong end of a Jedi as dangerous as Qui-Gon Jinn. As he says when a Jedi Master decides to Mind Probe young Obi-Wan and goes a bit overboard:
  " Sifo-Dyas can take a meditative retreat in the lowest Sith hell before I permit him to so much as touch my apprentice again."
• In the AU fic Double Agent Vader, Vader is very fond of Leia, who he thinks of as being like the daughter he never had. (It's very big on irony, this AU.) When she's a prisoner on the Death Star and she tells him she's willing to die for the cause, he responds that he would kill everyone on the Death Star first.
• Wilhuff Tarkin, Hero of the Rebellion has two examples:
  • Tarkin himself is one. Upon realizing his son had not been killed by the Atoan rebels but by Vader on the Emperor's orders to better manipulate him his first impulse is to try and take advantage of Vader's temporary weakness to kill him, before deciding to slowly manipulate him into a Heel–Face Turn to both have Vader destroyed by his own good side and screw with Palpatine. He also considers it acceptable for a father to cause immense loss of life in a Revenge by Proxy if the main target can't be reached:
    "Some people don't get a father's feelings. They find it funny. They look at the affection of a father for their child and laugh. Big, ugly, beasts. Fathers, I mean. Though you're quite generous, in my opinion-it's just less than two million people, quite the small revenge when you can't get directly your enemy."
  • As in the source material, Galen Erso sabotaged the Death Star to protect his daughter from the Empire and get back at them for separating him from his daughter and killing his wife. He also considers two million people as acceptable collateral damage to kill the people he holds responsible for that situation, namely Tarkin and Orson Krennic... And becomes a full Rebel collaborator once Tarkin points out it was Palpatine who twisted Krennic into the man who killed his wife and separated him from his daughter.
• In The Essential How-To Guide For The Engineering Jedi series, Darth Vader becomes a mentor and father figure to the new Executor head engineer Luke Lars. He becomes fiercely protective over the boy and does not take well to anyone with ill intentions towards Luke. Just ask Admiral Ozzel who was Force-choked when he insulted Luke one too many times. He only survived due to Luke's intervention.
• In Going Solo, Han gets ticked off when a holo reporter who’s doing a story on the Solos tries to go in Jaina’s room before she’s fully dressed and ready.
• Jaina’s First Date has Han complaining nonstop when Jaina goes on a date with Jag Fel at 15. He won’t stop being afraid it’ll lead to what he calls “terrible things”.
• Cleaning This Blaster has a classic “dad cleaning his gun while talking to his daughter’s date” scene with Han trying to intimidate Jaina’s date.

Transformers Film Series

• Optimus Prime and Ratchet in Things We Don't Tell Humans. Optimus is a fan of children, and Elita puts off telling him about how badly Quicksilver was treated because she knows he'll react badly (he does, and it's a little terrifying). Ratchet tries to pick a fight with a general who dismisses Prowl as just a numbers guy.
  • Ironhide is implied to be one (and seems to have adopted Sam and Carly). So is Tom Banachek, if the Autobots' dread of telling Tom and Dana about Faust's "capture" is anything to go by.
• Don't mess with Annabelle Lennox. Not only would that tick off her actual father, Will Lennox, but it will also anger the Autobot Weapon Specialist, Ironhide. And probably most of the other Autobots, who are rather fond of her. Barricade learned this the hard way.

It can only end one way for the terrorist gang. Especially when Mama Bear is assisted in the end by the soon-to-be grandfather of her child, who realises that this time his Assassin daughter might just conceivably be taking on too much. He steps in to fight for her. And wins.
  "Nine hundred and ninety times out of a thousand, your grown-up daughters are big girls who don't need you around any more." he said. "But on the thousandth time, a man had better be there for his girl, because she really will need him."
  "Good." Johanna said, feeling five or six again.

Harry Potter

• In Harry's New Home, Snape will go to any lengths to protect his ward Harry, even if it included breaking rules or facing the Dark Lord and Dumbledore (if necessary) to do it. For that matter, Dumbledore does not like seeing any of his students harmed in any way, especially if it's Harry. In the prequel, he gives a casual warning to Snape who earlier in a fit of rage slapped Harry. All in a cheerful tone and a benign smile.
  Dumbledore: You do understand that if you ever, ever again strike a student in so brutal a fashion, you will not survive the night, correct?
• In 3 Slytherin Marauders if you try and hurt Harry, Snape will end you... that is if Tom doesn't do it first.
• The Very Secret Diary: In Disenchanted, Arthur snaps after Dumbledore reveals that Malfoy was the one gave Ginny the diary. Dumbledore himself feels a touch of anger at Tom for badly traumatizing Ginny.

• In Mistaken Trust, Charlie is outraged and devastated to learn that Jacob has raped Bella. After Jacob kills himself to escape punishment, when Edward tells Charlie that he probably would have killed Jacob himself if Jacob hadn't beaten him to it, Charlie states that he'll pretend not to have heard that as chief of police, but as Bella's father, he concedes that he would have probably done the same.

Girl Meets World

• The Minkiad:
  • Stuart Minkus gets protective over Farkle many times throughout the fics. One of the reasons that he stays with Jennifer is so he could protect and take the abuse meant for Farkle. During the intervention, when Jennifer attacks Farkle, Minkus stands in front and has a Moment of Awesome defending him.
    Stuart Minkus: Now you are my wife and Farkle's mother, if either of those things ever meant anything to you, you will listen to what we have to say and you will: SIT! DOWN!
  • A phone call from Farkle only saying three words, “Dad,” and “ please help” is enough to send Minkus taking the red-eye to Rochester and to enter the Bassett home to look for his son. Minkus also protects Farkle from other people such as Meese. When Meese slaps him, Minkus cites this as a reason why his dismissal is so much easier for him. Cory also gets very Papa Wolf towards his children and his students at times. When Jennifer reveals that she knew that he called DFS on her Cory says "Yeah well I have this funny quirk that I don’t like when one of my students gets hurt, especially by their parents, the people who-oh, I don’t know are supposed to love and take care of them. The funny thing is the state of New York doesn’t really like it either. So I have this obsessive urge to step in."

As part of his plan, Ba'al stole Charlie O'Neill's corpse and brought him back to life in a sarcophagus (leaving a clone of Charlie in his place so nobody would know until Ba'al was ready), with the goal of using Charlie as a hostage to ensure that Jack would obey him. Unfortunately for Ba'al, having his son back drives Jack to ensure that nothing can threaten Charlie again, with the result that Ba'al is left stranded in a random location in Antarctica while Jack takes Charlie home in a puddle jumper Ba'al had acquired.

Star Trek

• Insontis:
  • Anyone who hurts or upsets the de-aged Kirk can expect to face Vulcan wrath. This includes crew members. When a visitor hauls Kirk up by his shirt, Spock reacts with cold fury.
  Spock was utterly expressionless, eyes devoid of anything but pure ice. That in itself was scary, because [the security team] knew that no one was as pure cool Vulcan as their Vulcan when he was restraining the urge to kill someone.
  • Kirk himself becomes more and more protective of his crew as he gets older, culminating in his saving them from the Klingons in one of the final chapters.
• Kirk (empowered by Khan's blood) in That Was A Good Fight. When a shapeshifting alien vampire thing threatened his crew, and specifically, Spock, they had to clean what remained of the creature out of the floor tiles.
• The fic Safe and Sound has a couple of examples:
  • Khan is the most prominent. Like in the film, he is this to his crew, and is prepared to kill Dr. Korby in the most painful way possible upon discovering that the man killed all but five members of his crew. He later nearly does carry it out after his surrogate daughter, Lucille, is taken by the man. Said surrogate daughter is able to convince him not to.
  • Spock gets a moment towards the end of the story. Korby kidnaps a pregnant Uhura too, and when Spock sees Korby hit her, he attacks him in rage.
  Spock: (through a forced mind-meld) You hurt my bondmate. You threatened my child.
  • McCoy also has a moment when trying to take back his daughter, Joanna, from his crazy ex-wife. "Once you took everything from me, including her...and hell, I'm not letting you take her again!"
  • Kirk to his crew, and Lucille. Note that in this story, he's empowered by augment blood.
• Spock again in the fic Written in the Stars, at least the Prime version. The Prime Fem!Kirk explains that when she was pregnant, she was taken hostage by the people of Gideon (TOS episode "The Mark of Gideon"). Lesson to be learnt: Don't kidnap a Vulcan's pregnant mate. It will not end well.

Supernatural

• In Deterioration of Reason, OC!Gabriel was already shown to be a protective big brother over Castiel and he gets angry if any harm comes to Castiel. But when the demon Belial, who had kidnapped and tortured Castiel, implied that he did something else to Castiel, not only does Gabriel go into Tranquil Fury, but it's revealed that God Himself has had enough.
  There was no way for the overwhelming wrath of God to be made evident through mere behavior. The archangel was no longer responding to the demon's mocking himself for the light that surrounded his already blinding form had no place on the conceptualized wavelength of mortal comprehension; it was the response of an incensed Father to the torture and ridicule of one of his sons, it was the vengeful mark of the Lord Himself.
• In Crossing the Line, John Winchester kills a human being for the first time because it was heavily implied said person had molested/sexually assaulted a ten-year-old Sam.

  The Warden: Uh oh...

Discussed by the BLU Engineer in Chapter 26 after Heavy and Pyro express wishes to kill the Administrator's Spy for sexually assaulting Scout:
  Engineer: Sorry, boys, but I think Red's earned the right to kill that son-of-a-bitch. I don't know if any of you are fathers, but I know that if someone had hurt my daughter, I'd take him out back and shoot his brains out for even touching her. I'm sure Red wants to do the same thing to Bane for what that snake did to his son.
  • Exploited by the Administrator, who knows that the RED Spy has a doomsday device activation code that she gave him many years ago when they were dating and which, in turn, is actually on a pair of dog tags that the RED Spy gave to the BLU Scout when he was little.
