Papa Wolf/Live-Action TV

"Rory: Where. Is. My. Wife?"
 * Step By Step: Frank was often the bumbling dad, much to the chagrin of eldest stepdaughter Dana ... especially when his attempts to play Papa Wolf result in (comical) failure. However, by the final act, when Frank plays things straight ... he is a very effective in warding off boys with undesirable ulterior motives. He never did this too much for younger stepdaughter Karen, as most of the sitcom dynamic was reserved for Dana's distaste with Frank. However, toward the end of the series, Frank played Papa Wolf for Al.
 * Little House On the Prairie: Several times, Charles playing watchdog over his daughters. More than once, Laura's husband-to-be, Almonzo, would be on the wrong end of Charles' wrath ... until Charles sees that "Manly" has pure motives. Indeed, Almonzo and Laura (despite their 10-year age difference) were a life-long couple, the (real-life) marriage ending only when Almonzo suffered a fatal heart attack in 1949, aged 92.
 * A very literal example is Leanbow in Power Rangers Mystic Force given that he is the Wolf Knight, when he becomes the red Wolf Warrior, he protects his son and his friends in a truly awesome battle. The same largely applies to his counterpart from Mahou Sentai Magiranger, save that all the core rangers are his children in that version.
 * Keith Mars from Veronica Mars, who previously gave off the impression of a Non-Action Guy, goes berserk when first season's villain tries to burn Veronica alive.
 * He is actually shown to be a Badass throughout the show, but in between the odd times that we ever see him get in a fight, most reports we hear of his exploits (he does a lot of work out of town chasing down bail jumpers) are Offstage Heroics at best, and an Informed Ability at worst. His ability to handle himself in a fight is in fact a Chekhov's Skill.
 * From the same series, the domineering, abusive Aaron Echolls seems oblivious that his daughter is being beaten up by her boyfriend, even appearing interested in starring in a movie he wants to pitch. However, at the start of what looked to be a pleasant dinner he administers one of the most comprehensive beatdowns ever seen on TV, before calmly concluding "I've decided I'm not interested in appearing in your movie."
 * Law and Order Special Victims Unit: Elliot Stabler's kids may as well be his Berserk Button, he once almost beat a pedophile half to death for posting pictures of his (underaged) daughter on an internet site. Then again, given that the only thing that keeps him doing that on a regular basis is that he can't use torture as a means to extract confessions, and once removed of that restriction, he quite gleefully beat into another suspect...
 * Odafin "Fin" Tutuola also counts: he points out that if it had been his kid, there would have been no "half" about it.
 * A number of the female victims father found out that someone had killed his daughter and went out and killed the perp.
 * Ace Lightning's Simon Hollander is a mild mannered accountant - until you insult his son.
 * In Twenty Four, do not mess with Jack Bauer's daughter. You will regret it. i.e., the end of season one, when Kim has escaped from her captors, but the villains still want to lure Jack in, so they have The Mole tell him that his daughter's body had been found. Seriously. Bad. Idea. Jack comes in, all right -- both guns blazing -- and doesn't leave a single one alive, even emptying an entire magazine into the surrendering Big Bad. There is a good reason why he is the Trope Namer for the Jack Bauer Interrogation Technique.
 * Doctor Who: "You just killed someone I liked, and that is not a safe place to stand. I'm The Doctor and you're in the biggest library in the universe. Look me up."
 * About 5-10 minutes or so after the Doctor finally accepts Jenny as his "daughter," so to speak, in "The Doctor's Daughter," The next minute is one of the only times in the series where we see the Doctor holding someone at gunpoint.
 * Also "NO FORCE IN THE UNIVERSE CAN STOP ME NOW!" when in "The Idiot's Lantern." I think it's fairly safe to say that you just don't mess with the Doctor's companions. Ever.
 * It's not just the New Series that has the Doctor going all Papa Wolf when his companions are endangered. I submit the cliffhanger to Episode 3 of the Caves of Androzani as exhibit A
 * When finding Sarah strapped to a rock and tortured in The Sontaran Experiment, the Doctor utterly blows his tactical righteous cool and starts swearing and trying to beat up the Sontaran leader. This does not go well for him, which he would've known if he weren't blinded by rage.
 * In episode Amy's Choice, the Dream Lord remarks on the Doctor's tendency to swell in masterful fury when someone he cares about is threatened.
 * Series 6 turns this Up to Eleven in its midseason finale, where the Doctor gathers a literal army to rescue Amy and her daughter. But this is outshone by Amy's husband Rory, who dons Roman centurion armor and a sword and fights his way through an entire Cyberman starship just to ask them a question:
 * Series 6 turns this Up to Eleven in its midseason finale, where the Doctor gathers a literal army to rescue Amy and her daughter. But this is outshone by Amy's husband Rory, who dons Roman centurion armor and a sword and fights his way through an entire Cyberman starship just to ask them a question:

"Atraxi: You are not of this world.
 * "I'm Rory Williams. I'm here to kiss my wife or kick your ass. AND I DON'T SEE MY WIFE."
 * Series 5, The Eleventh Doctor acts as a Papa Wolf for all of humanity to the Atraxi with a little history lesson in the first episode. Safe to say, this speech solidified Matt Smith as The Doctor for those who weren't already convinced (such as this Troper).

The Doctor: No, but I've put a lot of work into it.

...

The Doctor: Okay! One more, just one more... is this world protected?


 * cue montage of aliens who have attacked or threatened humanity*

The Doctor: But you're not the first lot to have come here. Oh, there have been so many! And what you've got to ask is... what happened to them?


 * cue montage of the previous ten incarnations of The Doctor, ending with The Eleventh stepping through the image of The Tenth*

The Doctor: Hello. I'm The Doctor. Basically... run."

"Danny: If you ever bring a gun into the same zip code as my daughter again, I will put a bullet in your head."
 * Michael has a Papa Wolf moment in Arrested Development when trying to get back with a girl he was dating. He stops his sister and mother from physically attacking her in a restaurant for writing an unflattering article about the family. Then he hears that she told his son to stop getting in the way of Michael's happiness. He steps out of the way and tells the girl she's on her own. She promptly gets her ass kicked.
 * Danny "Danno" Williams in the Hawaii Five-O reboot. Moving to the other side of the continent is the least he'll do for his daughter Gracie.
 * Half of the episode "E Malama" is basically Danny being this. Never endanger the life of his daughter.

"Lilah: Look, Angel, I know you've been out of the loop for a while, but I'm still evil. I don't do errands. Unless they're evil errands.
 * Phillip "Uncle Phil" Banks from The Fresh Prince of Bel Air is known for his anger, but in the episode, Mistaken Identity, when a racist police officer arrests his son Carlton and nephew Will, and sees right through an obvious Engineered Public Confession. When said cop refuses to let them out of their cell, Uncle Phil unleashes a verbal ass-whoopin' the likes of which the poor bastard had never seen.
 * Another example of Uncle Phil's Papa Bear badassery is when the parents of Ashley's school bully advise that they seek psychiatric help for her. Long story short, shit gets real.
 * A third example is when Will's father Lou shows up. As Lou is preparing to leave...without Will and asks Uncle Phil to let him know... Phil unleashes a verbal beatdown on Lou not seen since the Mistaken Identity. And it was glorious.
 * He also out-hustles a pool hustler who tried to cheat Will out of thousands of dollars!
 * In Heroes, the uber-example is Noah Bennet aka "Horn Rimmed Glasses/HRG", Claire's adoptive father. For one thing, when Claire Bennet was shot shortly after losing her powers (primarily to protect her dad), and was also slowly and painfully dying due to not having ever been sick in her life prior to this, he attempted to get revenge on Sylar by shooting him and went on a manhunt. His protectiveness of Claire Bennet and unwillingness to hurt her or let her get hurt was also what caused Claire to immediately deduce that the sniper who was gunning down the carnival members was not actually HRG, as the sniper managed to graze her in the arm, something that HRG would never have done even if he did attempt to gun down the carnival.
 * This is also true for Dr. Mohinder Suresh and Matt Parkman, the surrogate parents of Molly Walker. They're white hats, though, so they're not as extreme in their protective measures as Mama Bear Jessica or HRG.
 * Future!Sylar becomes a Papa Wolf. He's gone from a homicidal psychopath to a cuddly, waffle-making single father because he keeps his murderous instinct in check for his son's sake... and when said son in killed in the crossfire of a battle between Peter and the Company, Sylar literally goes nuclear and takes out the entire city.
 * Lampshaded on Angel: Lorne comments on Angel's strong "Mama Bear Vibe" when he becomes aggressively over-protective of his newborn son. The trope was shown in its full glory when Angel almost smothered Wesley to death after Wesley unwittingly made Angel lose his son.
 * Then there was this conversation with Lilah:

Angel: I think you'll do this one.

Lilah: Why? What's in it for me?

Angel: Just this once, I'll ignore the fact that you're within fifty yards of my son. Just this once."

"Angel: Don't do that!
 * And of course, there was his little speech to Linwood in "Dad" where he promised to inflict upon him any pain Connor experiences, even when Wolfram&Hart couldn't have possibly had anything to do with it.
 * In The Sarah Jane Adventures, Alan Jackson is none too pleased when aliens abduct his daughter and try to Ret Gone her.
 * In Battlestar Galactica Reimagined, Commander Adama has repeatedly referred to his crew as a family and came dangerously close to sparking off a civil war
 * The scene where he threatens Admiral Cain is both a Moment of Awesome and example of Awesome Music. "Prelude to War" is a masterpiece and it fits the scene so well. It makes Adama's Papa Wolf-ness that much more badass.
 * Earlier than that, in the first season episode "You Can't Go Home Again", when Adama puts the fleet and resources in serious jeopardy before giving up on a hopeless rescue operation to recover Starbuck. When his son, who has something of an inferiority complex with regards to the Commander's and Starbuck's relationship, asks if the Commander would have stayed so long if it had been him down there, Adama asserts that if it were him, they would never leave.
 * Lost:, of all people, goes all Papa Wolf on 's ass - but with disastrous consequences, and too late to do any good.
 * Very darkly used when  is taken away by the Others, and his father   not only betrays the group under their orders, but also , all while attempting to protect his son.
 * Firefly's Malcolm Reynolds is a Papa Wolf, and in his case, it applies to anyone on his crew. Threaten someone on his crew, and you are in for an extreme world of hurt.
 * In a similar vein, Simon is this way with his long-suffering sister River. He's normally a relatively unassuming and actually quite timid doctor who isn't that good at combat, but when River is in danger, he goes all-out to protect her.
 * I wonder how many times Jubal Early has gotten slammed into a bulkhead by a 140 pound doctor, shot him and then got knocked down by him again?
 * And while we're at it, don't hurt Kaylee. Jayne will make you pay if you hurt her. For that matter, so will Simon. And Mal. In fact, just don't hurt Kaylee. As Jubal Early can attest, it won't end well for you. Well, he could if he hadn't been.
 * Team Dad Giles of Buffy the Vampire Slayer. The welfare of the Scoobies is this normally quiet and reserved librarian's Berserk Button.
 * In one episode of season five, Spike comes by asking about Buffy. The Scoobies tell him he's not welcome, and when he doesn't get the message, Giles picks him up by the throat and menacingly warns him away from Buffy. All this time, Giles looks about ready to chuck Spike right into the sunlight.
 * There's also "Graduation Day Part 1" where the Mayor nonchalantly mentions his plan to eat Buffy and Giles, without blinking, picks up a sword and stabs him through the chest.
 * The Mayor is this himself to his Dragon Faith, with whom he shares an oddly touching father/daughter relationship. When Buffy puts her into a coma, he first tries to smother Buffy in a Tranquil Fury, then has a miniature Villainous Breakdown, dropping his usual Affably Evil persona:

Mayor: Oh, I will. I'll do worse! Murderous little fiend! Did you see what she did to my Faith?!

Angel: I got no plans to weep over that.

Mayor: Yeah, well, I'd get set for a world of weeping! I'd get set for a world of pain! Misery loves company young man, and I'm more than willing to share that with you and your whore!"

"Gil Grissom: Let me tell you something, Humbert. You're twice the age of these kids, and half of them couldn't find their own ass with a map. You prey on innocent children, concocting God-knows-what from God-knows-where, selling Russian Roulette in a bottle and you think we came all the way out here to bust you for possession, you dumb punk? I'm gonna get you for murder. Cool?"
 * Another Simon, this time the Magnificent Bastard from Flash Forward 2009. While definitely not a Nice Guy, he is very protective of his family, especially his younger sister Annabelle.
 * Aaron Stark also qualifies.
 * Jack Bristow of Alias is a Papa Wolf extraordinaire for his Action Girl daughter Sydney, despite being absent for much of her life due to his job with the CIA. Some of the more memorable instances include the very first line he says in the series being him asking about Sydney's safety (deliberate on the part of the writing staff); breaking another agent's fingers in a vise after finding out he's a traitor, then shooting him in the head after he confesses to exposing Sydney's cover; and entering a fatally radioactive room to ensure her escape.
 * This is all nothing compared to his retaliation against his own wife, Irina Derevko. In "Dead Drop", he believes Irina isn't genuine in her desire to help the CIA, so he, which makes Sydney believe her mother lied to her and meant her harm. As we see in "Search and Rescue", he even   because he believed she ordered a hit on Sydney.
 * Aaron Hotchner of Criminal Minds is without a doubt Team Dad to the entire team. And he is not a dad you want to mess with. Although, considering his workaholic tendencies and his eventual divorce as a result, he's often a better dad to the team than he is to his actual son. He even plays Papa Wolf to children involved in their cases.
 * Dave Rossi reaches Papa Wolf status in "Masterpiece" when Henry Grace goes after the team to get to him. He spends the entire interview convincing Grace he's got the power, then, in one line ("Did you get all that?") Out-Gambits Grace by revealing he's been playing Grace the whole time, slamming Grace's head against a window for going after his team.
 * Hotch and Rossi's co-parental status is lampshaded when team super badass/older brother Derek Morgan asks, "Where's Mom and Dad?" to which team organizer/big sister JJ responds, "Hotch and Rossi are still at the conference." No mention of which is which, but it's worth noting that Hotch's status as Team Mom has been a running gag in fandom since season 1.
 * Hotch invoked this trope all over the recurring villain who came after his own family.
 * There is another episode where the kidnapper of a girl turns out to be just a lustful teenager, and the girl's father turns out to be a retired mafia hitman. Hilarity Ensues.
 * In Charmed, Leo spent the first half of season 6 in Papa Wolf mode after both his sons were put in danger.
 * In Dexter, Dexter Morgan intentionally breaks his rules for the first time in order to He even compares himself to a wolf directly in  In general, he seems to hold a particular antipathy for any of his victims who victimize children.
 * In Season 5 he beats the snot out of an abusive stepdad (whose stepdaughter was friends with Astor, Dexter's own stepdaughter) and runs him out of town, partly to help out the girl being abused, but also to ensure the abuser never goes near any member of Dexter's family.
 * In Season 6, Dexter considers lettint the police catch the Doomsday Killer,
 * Gibbs of NCIS WILL hunt you down if you ever harm his team. Especially Abby... not that she usually needs rescuing.
 * In one episode, Gibbs tag-teams with his FBI counterpart Fornell after a suspect tried to kill the NCIS/FBI agent pair escorting him.
 * Gibbs' own backstory involves him hunting down and executing the Mexican drug lord responsible for the death of his first wife and their daughter.
 * In the episode "Twisted Sister", McGee goes Papa Wolf in his effort to clear his little sister.
 * Sniper Gibbs shoots a terrorist holding Ziva captive in a Somalian prison, from 1,000 yards, in the seventh season episode "Truth or Consequences." Ziva's partners Tony Di Nozzo and Tim McGee are deliberately captured and endure torture to give Gibbs a chance to set up the shot and rescue Ziva. In the seventh season episode "Good Cop, Bad Cop," Gibbs sends a message to Ziva's father, the Mossad director, who sent her on a suicide mission and then left her to die in Somalia, that "She is off limits!" No one messes with Ziva on Gibbs' watch.
 * In the fifth season episode "Requiem," Gibbs beats up a man who is harassing his dead daughter's childhood best friend, Maddie Tyler, and later rescues her from her kidnappers.
 * In one episode there is a Flash Back in which young Gibbs is in a fight with a bully and his dad comes out and fires a shotgun in the air. Which would indicate that it's In the Blood.
 * Luke from Gilmore Girls, Rory's father figure, goes Papa Wolf quite a few times, one of these even leading to Lorelai proposing to him.
 * Cruelly subverted in Oz. When Vern Schillinger's son Andrew arrives in Oz, Tobias Beecher, Ryan O'Reily and Chris Keller seize the opportunity to get even with Vern. Vern eventually concludes that he'd rather kill Andrew himself than to see him subjected to a Fate Worse Than Death. When the trio hears of Andrew's death, they just quip: "It worked."
 * Eric does this a few times in Boy Meets World. Mostly he is a Ditz and sometimes he is a Woobie. But he can be a Papa Wolf to Cory and when he stood up to a bully bigger than him it was a Crowning Moment of Awesome.
 * Torchwood: Team Dad Captain Jack Harkness fits this whenever his team is put in danger... especially when it's perceived to be his fault (directly or not). All you have to see is him charging in to save his team with swishing coat and one heck of a gun in "Countrycide" to realize that you don't mess with Torchwood.
 * Somewhat subverted in Children of Earth when
 * From Torchwood Miracle Day Miracle Day]]: Known murderer and paedophile Oswald Danes is in Gwen and Rhys' house and makes the mistake of laying a hand on their daughter. Rhys spends the remainder of the episode threatening to kill him. Danes even notes at one point that Rhys would probably do it.
 * Mork from Mork and Mindy. Don't make fun of his son Mearth. Just... don't.
 * Supernatural: Averted Trope with John Winchester, who doesn't let his sons' welfare get in the way of his job. Played with in that Dean is not only Sam's older brother, but also his parent in many ways. Dean's already a Badass, so don't mess with Sammy.
 * Actually, John has frequently shown a reluctance to put his boys in danger and even wasted one of the Colt's precious bullets to kill a vampire that was threatening Sammy. Even after he was dead, he climbed out of hell to kick Azazel's ass when he attacked the boys. If anything, John transforms from a Badass to the incarnation of the Wrath of God when Dean or Sam are in trouble.
 * There's also the fact that he sold his soul and the only weapon that could kill Azazel (who he'd spent the past 20 something years hunting) to Azazel to make sure Dean would live. The man may not be the most stellar father, but it can't be denied that he does try.
 * A man named Jimmy Novak is dying, and then is told that his daughter Claire will be the vessel for the angel Castiel. He demands that Castiel use him and spare poor Claire the trauma of seeing everything Castiel has to do, even though it means he'll never see his family again. Castiel accepts, and Jimmy becomes the Soul Jar of sorts for him and the Cas we know.
 * Stargate SG-1: General Hammond is usually the level-headed, occasionally obstinate commander of Stargate Command. But when you threaten his people (especially SG-1), you'd better run.
 * When SG-1 was captured by a System Lord, he sent four teams to rescue them, and when they were captured as well and his superiors ordered him not to risk another rescue mission, he went offworld to gather help to rescue them himself. He and Teal'c end up piloting a fighter through the damn Stargate, while Hammond shows his Texan heritage with a hearty "Yeehaw!"
 * When SG-1 was sent back to 1969 in a freak accident, Hammond sent a note with them, which said only "Help them." His thirty-years-younger self found the note and indeed decided to help SG-1 escape custody, solely on the basis of recognizing his own handwriting.
 * When SG-1 was nearly killed while trying to uncover an Ancient weapon to save the planet, it was Hammond who saved them at the last minute, by personally taking command of Earth's lone spaceship and giving them enough time to save the world...again.
 * In Burn Notice Michael Westen often accuses his little brother of being a ne'er-do-well. But when his little brother is in trouble he'll always stick up for him. It is not safe to pick on Michael Westen's brother.
 * While we're at it, it also wouldn't be wise to hurt Michael's mother.
 * Several of Michael's clients are as well. One takes a beating and doesn't lose his cool because his son's being held hostage. Another, on seeing a con artist who sold fake medicine that made his son's health worse, jumps out of a car, chases the guy down and beats the crap out of him.
 * In Married With Children, Al Bundy is hardly a model dad, but he will stand up for his children when needed. A Running Gag is that he'll discover a sleazebag making out with his daughter, drag him to the front door and slam him against it before tossing him out of the house. In one particular episode, Kelly spots her boyfriend with another girl. She simply tells Al, "Daddy, beat him up," which he promptly does.
 * On CSI, Grissom (who is just about as mild-mannered as they come, and at this point had few moments in which he lost his temper) gave Catherine's abusive ex an Oh Crap moment by letting out a very loud "Hey!" and looking all the world like he was going to charge down the hallway when Eddie tried to bully her.
 * There's also this memorable rant, showing that you do not fuck around with kids on Gil Grissom's watch:

""What did you just call him?!""
 * Ditto with CSI: NY's Mac Taylor...it's shown up several times with Lindsay in particular. In the ep where the lab was shot up, Mac crashed through his half broken office window to pull her out of the line of fire after she basically had a panic attack, apparently.
 * The same probably also goes for Horatio Caine on CSI: Miami.
 * And Angela's dad as well.
 * Mama Bear and Papa Seahorse became proud parents of this trope on Alien Nation, when pregnant Newcomer George Francisco broke with his usual self-controlled civility to utterly cream a thug in defense of the fetal Newcomer in his belly-pouch.
 * Agent Booth from Bones won't hesitate to hurt or kill if anyone tried to get too close to Brennan. He is fiercely protective of her, escaping from the hospital despite his injuries in order to save her from a crazy ex-FBI agent.
 * Booth wasn't happy when Howard Epps escaped from prison. But when Epps got close to Booth's son Parker, he went full-on Papa Wolf.
 * He's also willing to give up a promotion, a raise and a trip to Hawaii to keep his little brother from being dishonourably discharged.
 * Matt Brennan, aka Max Keenan (father of Bones) once killed, gutted, and then burned the corpse of someone who was hired to kill his children. In an earlier episode, it's mentioned that despite being a career criminal, he tried to avoid violence whenever possible. Killed, gutted, then set on fire.
 * Glee: Kurt Hummel's dad Burt may not understand his son's obsession with musicals and dancing but when Kurt is refused a solo on the grounds of being of the wrong sex for it, he goes to the school and shouts at the principal and the teacher until Kurt is given a chance.
 * Papa Wolf status confirmed when he rips Finn a new one and throws him out of the house for calling Kurt a fag. Also a Crowning Moment of Awesome.

"Toby: I'm told that on my sunniest of days I'm not that fun to be around. I wonder what's going to happen when you make my children a part of your life."
 * Then there's what he's inches away from doing to Karofsky before Kurt pulls him off. Which is not too long after suffering  to boot...so, simply put? Do not mess with Kurt Hummel; you won't like the results. And he didn't even know the real reason Karofsky was threatening Kurt...
 * In Noah's Arc, Ricky actually fits in this regards to Noah at times, despite not being his father. Ricky introduced Noah to much of the gay scene, and shows increasing protectiveness of him as the series goes on, doubling as a friend and mentor at times. Whenever he feels Noah is in danger, he immediately goes into Papa Wolf mode.
 * Psych: Henry has his moments in cases where Shawn is in danger. 'Shawn takes a shot in the dark' anyone?
 * From ER, we have a few doctors who would go to far lengths to protect their patients. Dr Kovac once yelled at a father for leaving his young daughter alone in the waiting room for some time while he was working, where there were druggies and other not-so-sane people around. Another time, when he suspected the husband of his patient was abusing her, he went to confront him and was fully willing to put himself in danger (hence getting punched as a result) to prove to the authorities that the guy was a danger to his wife and others.
 * Another time, Ray found out his ex-girlfriend had an abusive father. He helped her get away from him and when the father tried to catch the car, Ray flattened him with a punch.
 * Don't forget the time when Malucci found out that a little girl he was tending for was sexually abused by her dad. After hearing about the "games" he played with her, the poor guy's mind completely shut off... and then he burst into the operation room where the father was being treated and beat him up while crying and screaming.
 * Uther Pendragon, from Merlin. For all of the man's flaws, it really is not wise to mess with either Arthur or Morgana. He will kill you dead.
 * A non-parental example on the same show is Merlin toward Arthur and Guinevere. A memorable scene in season three is Merlin telling Morgana in no uncertain terms that if she dares hurt either of them, she'll be going down hard..
 * Clark Kent on Smallville, whenever children are in harm's way. Also Jonathan Kent and later on, Lionel Luthor.
 * Jonathan Kent was actually pretty legendary in this regard. One memorable scene was when Lionel tried to blackmail him again, or he'll expose Clark's secret to the world. He chose to beat seven shades of crap out of Lionel, nearly killing him, until he was struck with a heart attack, and died. He literally sacrificed his life to protect his adopted son.
 * Granted, the situation was not quite what he thought it was (Lionel was actually on the way to a Heel Face Turn at this time, and himself took Clark's secret to the grave 2 Seasons later), but given Jonathan's history with the Luthor family, his overreaction is understandable (and Lionel even admitted his fault in Jonathan's death).
 * Dr. Cal Lightman of Lie to Me may be a Bunny Ears Deception Expert who has kind of a bad-boy vibe going on. But should you so much as threaten his daughter Emily (whether you're a punk kid or a cop or a federal agent), Cal will destroy you.
 * Averted in Republic of Doyle. Malachy could care less about Jake.
 * Police Commissioner Frank Reagan of Blue Bloods unhesitatingly shoots and kills the rapist/killer who was threatening his Assistant DA daughter, Erin; who had prosecuted the guy a few years earlier.
 * Raising Hope: Burt Chance loves his family. When his rock hero insults his wife, son, and granddaughter all at once, he gives the jerk a guitar to the back of the noggin. He even got a youtube mix out of it!
 * The West Wing. President Bartlett had a very memorable rant about what would happen if something happened to his daughter Zoey, calling it "the nightmare scenario", since "this country no longer has a commander-in-chief but has a father who's out of his mind because his little girl is in a shack somewhere in Uganda with a gun to her head!"
 * Played straight on several other occasions, notably when Bartlet believes a reporter has approached his daughter Ellie despite strict rules forbidding them to do this.
 * Toby is also a straight example before his children are even born:


 * In The Office Stanley goes after Ryan pretty hard when he thinks he may be "sniffing around" his daughter.
 * Prison Break: Linc to his son LJ, Michael to his nephew LJ. Alex to his son.
 * Linc, who is ready to tear Alex apart at the first opportunity, in season four finds out
 * Floyd Henderson in Smart Guy doesn't actually get a chance to demonstrate his Papa Wolf potential, but in the episode Strangers on the Net, after TJ admitted to Floyd that a man posed as a kid on a kid's chatroom and later has the guy arrested (who also turned out to have been arrested for this sort of thing before and placed on prohibation), and was unlikely to be getting out of jail anytime soon due to breaking prohibation, Floyd remarks "Lucky for him" when hearing this, implying that he intended to do far worse to him as soon as he got out.
 * Ray Campbell in Sister Sister had one of these moments when the twin daughters (well, technically Tamera only, Tia only went after it became apparent that Tamera snuck out of the house in an attempt to get her back home, but her plan ended up backfiring) attempted to meet Verique, who despite his identity on the web, was actually a sex offender who often lures women into posing for dirty pictures. As soon as Ray and Lisa found this out (as well as where he lives due to directions), after the twins attempt to escape but fail, Ray and Lisa appear behind him and, in a Crowning Moment of Awesome, punches Verique in the face after Lisa shouts "What's love got to do with it, ya punk?!"
 * Sheriff Jack Carter of Eureka. A nice guy who'd rather avoid nuclear anything, much less the radiation that comes with it. However, when his smart house goes crazy and targets his daughter, Zoe, with a destructo raygun, he breaks out his prized World Series autographed bat and wails on the house's nuclear generator in the hopes of knocking off the power... Which theoretically would have killed him and the five people trapped in the house with him. Sorry Boss, Best-Friend, Love Interest, and two mostly innocent bystanders, Jack's daughter ranks above all of you.
 * Walter from Fringe was literally willing to destroy the fabric of the universe in order to save  his son.
 * Despite Modern Family's Cameron being overly dramatic and somewhat effeminate, when he thinks there's a stranger in Baby Lily's room he jumps out of bed, grabs a baseball bat, and charges in with a Pre-Ass-Kicking One-Liner.
 * Alvaro Cueva, Mexican critic of Alta Definición fame, HATES seeing children being treated as idiots by some shows, and exploited (made fun of or worse, making kids dance in ways pedobear would approve) by others.
 * Breaking Bad: Walt White is not too fond of people making fun of or hurting Walt Jr. or Jesse. If you do either of those, prepare to PAY for it, and pay it dearly.
 * Scorpius, the original Big Bad of Power Rangers Lost Galaxy goes on a rampage when he thinks the Rangers have kidnapped his daughter Trakeena. It ends badly for all involved.
 * In Power Rangers Dino Thunder, Tommy does not take kindly to his students being threatened. In one episode, Zeltrax taunting him with their deaths results in Tommy seriously wounding the cyborg.
 * Should you happen to be in a coma, whether you're listening to Life On Mars or Ashes to Ashes don't mess with anyone under Gene Hunt's protection. Don't.
 * In Rizzoli and Isles, Maura Isles' biological father Paddy Doyle stabbed a rival mobster in the heart with an icepick to prevent him from killing Maura the way he'd already killed Doyle's son. On the dead man's chest was a blood-stained photo of Doyle holding Maura as a baby, pinned there with the icepick. Doyle's message: "Don't mess with my family." Doyle told Maura to call him with the murderer's name and he'd "send the man a message" but Maura couldn't do it, even if it meant she would be murdered. It's strongly implied that another Papa Wolf, Jane Rizzoli's ex-partner Vince Korsak, called Doyle to protect Maura.
