8* ''Series/TheAfterparty'':
9** Aniq is one of the nicest guys you'll ever meet, but [[spoiler:as Xavier finds out,]] even he has his limits. This is also somewhat [[{{Deconstruction}} deconstructed]]; despite his friends' insistence, Danner recognizes that it is possible to push a guy like Aniq to violence, [[spoiler:as Walt's flashback proves]], meaning he's just as suspicious as anyone, and his account and history of animosity with Xavier makes him the prime suspect.
10** [[spoiler:Yasper is shown as kind and supportive towards his friends, but after getting rejected by Xavier and feeling like his work was stolen by him, he murders his former bandmate]].
11* ''Series/AllInTheFamily'':
12** "Edith's Problem", the classic episode known not for its treatment of a typical American woman having trouble dealing with menopause symptoms, but Edith's irritability as she goes through the early stages. Most punctuated by Archie's well-meaning but ill-advised attempts to deal with his wife — oh, just "Stifle, stifle, STIFLE!"
13** Lionel Jefferson, the young black neighbor of the Bunkers who usually playfully tried to expose Archie's bigotry when Archie tried in his bull-in-a-china-shop way to mentor Lionel on the ways of the world. In "Lionel Steps Out", Lionel tells him exactly what he thinks of Archie's attitudes when he crosses the line and tries to stop him from dating his white niece.
14* ''Series/{{Alphas}}''. Dr. Rosen, with his Mr. Rogers sweaters, scruffy beard, soft voice, and herbal remedies seems like a flower-child gone to seed; one can imagine him in his youth leading peace rallies. However, when those he loves are threatened, or worse HURT... watch out!
15* Rommie in ''Series/{{Andromeda}}''. A nice, polite, and considerate young woman who just happens to be able to blow up a planet.
16* ''Series/TheAndyGriffithShow'': As many a crook who's dared to cross him found out the painful way, this very much applies to Sheriff Andy Taylor.
17* ''Series/{{Angel}}'':
18** Fred was usually sweet and gentle but on a few occasions, she had her inner badass released.
19*** In "Deep Down" she goes wacky on Connor with a taser when she discovers his complicity in [[spoiler: Angel being sent to the bottom of the ocean]].
20*** Upon discovering in "Supersymmetry" that [[spoiler:her physics professor sent her to Pylea]], she plotted all sorts of nasty revenge, leading to the immortal line "You know what they say about payback? Well, I'm the bitch."
21*** "Although I thought I might just shoot you in the throat instead. Now, if I pierce one of your carotid arteries, considering the temperature in here, 'cause I think somebody shot the thermostat, the blood loss is gonna be heavy. And there's a chance I'll puncture a vocal cord and you won't even be able to scream. But you'll want to when the blood loss to your brain results in a cerebral vascular event. That's a stroke. I wasn't trying to sound snooty."
22*** In the hell dimension in which she was trapped for five years, the cave she hid out in had a handy nearby ravine that she used to dispose of bodies.
23** Lorne, the one member of the team who so rarely does any fighting.
24*** He has this to say when [[spoiler: Fred is lying on her deathbed]]: "If I hear one note, one quarter note, that tells me you had any involvement, these two[[note]]Angel and Spike[[/note]] won't even have ''time'' to kill you. Oh, and [[TakeThat anything by Diane Warren will also result in your death]]."
25*** Don't forget, if he ever hears you singing, Lorne will know all your secrets and usually some of your future. This makes his rare [[BreakThemByTalking breaking speeches]] very effective.
26*** Nothing really tops the moment when he [[spoiler:shoots Lindsey in cold blood without so much as twitching. With a ''silenced pistol'' at that, all professional like]]. Did the guy deserve it? Probably. Was it out of character for Lorne to do it? ''Definitely.'' He makes it obvious that he thinks Angel has asked too much of him, but he still goes through with it as a final act of loyalty.
27** The Groosalugg is probably the nicest guy after Doyle, yet just as badass as Angel. Speaking of which...
28** On a good day Angel fits the FriendlyNeighborhoodVampire trope like a glove. When he is not having a good day: as Angelus he is one of the worst villains and when Darla and Drusilia push him too far he ditches his SuperpoweredEvilSide mind games and keeps his viciousness, they are ''freaked'' upon discovering this.
29** Wesley is a nice, proper English Watcher. And then at the end of Season 3, Justine had Angel locked in a coffin and tossed in the ocean. Come next season, Wesley has her in chains and a SlaveCollar in a cage. At one point he halts an escape attempt with a single emotionless sentence.
30--->"I'll take away your bucket."
31* ''Series/TheAstronautWivesClub'': Gus Grissom is the most unambiguously kind astronaut, while his best friend Wally Schirra is the prankster of the group. But when trouble strikes, both are fully capable of a terrifying TranquilFury, as seen when Gus defends his mission and Wally pushes forward after [[spoiler:Gus dies.]]
32* Russell Glasser of ''Series/TheAtheistExperience'' is often seen by theist callers as the safest one to talk to. This is a misconception as his comments cut deeper and deeper as he slowly loses his patience with you.
33* ''Series/BabylonFive'':
34** Vir Cotto is just about the sweetest, kindest, and most dorkily cute character in the series. However, when driven into action he can become a terrifying force. His acts of badassery include, but are in no way limited to: [[DidYouJustFlipOffCthulhu flipping off Cthulhu]], assassinating an insane Emperor, staring down a demon (it was a hologram, but he had no way of knowing that at the time), and demolishing a market stall belonging to a Drazi spy with one of Londo's duelling swords.
35** John Sheridan is a polite and affable chap, always ready with a boyish grin and a story about his [[WackyFratboyHijinx Academy days]], which makes you wonder how this man earned the monikers "Starkiller" and "Nukem". Then something happens, the smile evaporates, and you are left with a [[TheDeterminator very determined]], [[TranquilFury icily livid]] and completely ruthless warrior.
36** Lennier also shows tendencies of this, when the BadassBookworm decides to put aside the "bookworm" part of the trope.
37** Delenn is the seemingly mild-mannered religious caste Minbari, whose mentor once said: "If you want to make a point, why not make it [[ThereIsNoKillLikeOverkill so that no-one misses it?]]". She took it to heart by breaking a would-be rapist's finger, beating a group of attackers into unconsciousness with a quarterstaff, obliterating an enemy fleet (including civilian passengers) that was meddling in Minbari internal affairs, and by (ultimately unsuccessfully) waging genocide against humanity after they pushed her just a little bit too far. It's no wonder Delenn ultimately ruled the galaxy as her personal fiefdom for the better part of a century.
38* The title character of ''Series/BarneyMiller'' is a police captain with a truly astonishing level of patience who emphasizes using understanding, compassion, and above all ''perspective'' when dealing with the public. But there are several points throughout the series where {{Obstructive Bureaucrat}}s, inability to press charges against criminals who are actually dangerous (rather than ordinary people who snap and calm down after he leaves them to think for a while), or the apparent futility of police work drive him over the edge and he unleashes a verbal explosion.
39* ''Series/{{Barry}}'':
40** Subverted when the AffablyEvil [=NoHo=] Hank believes that Barry has screwed him over, he drops his friendliness and says seriously, "Don't fuck with me Barry... it's not polite." [[spoiler:He then thoroughly bungles his assassination attempt on Barry and immediately makes up with him]].
41** Played totally straight in the Season 3 finale [[spoiler:as Hank, after being terrified by hearing his friends being mauled and eaten by a panther, escapes his captivity by gunning down the panther and several Bolivians, including Cristobal's wife Elena. The look on his face after he's reunited with a traumatised Cristobal suggests that he's no longer going to be so squeamish about personally killing anyone after that.]]
42* In ''Series/BattleBots'', Paul Ventimiglia is one of the most soft-spoken and polite team captains in the history of the competitions. However, his robot, Bite Force, is one of the most serious threats out there, having only lost once in the 13 matches it's been in, was the first bot to prevail over the seemingly-unstoppable End Game, and is so far the only bot to have decisively defeated [[TheDreaded Tombstone]].[[note]]Said loss was to Chomp, whose axe swung down into a tiny hole exposing its inner parts that [[WreckedWeapon disabled Bite Force's weapon]] and hampered its movement, a move with such incredible accuracy that [[Film/ANewHope Luke Skywalker]] would've been proud.[[/note]]
43* ''Series/{{Battlestar Galactica|2003}}'': You won't believe who overthrew the Galactica's military. [[spoiler: Felix Gaeta! Not only that, he ordered the murder of President Roslin!]]
44* Annie of ''Series/{{Being Human|UK}}''. A ghost who is generally sweet and shy, who's never actually been in a fight, and comes across as being the most soft and kind of the threesome (the others are a vampire and a werewolf). But then she remembers [[spoiler:her ex-fiancée killed her]]. At first her attempts to spook him meet with epic fail. Then she corners him, reveals what her flatmates are. And then she whispers something so horrifying to him that he breaks down in tears, runs screaming and BEGS the police to protect him. Bear in mind [[spoiler:her ex]] had previously been completely unrattled by coming face to face with a ghost and was a monstrous SmugSnake with no redeemable traits... and she reduces him to a whimpering mess with a few words. [[https://www.youtube.com/watch?v=t5hZEIxgGKQ DO NOT get on this girl's bad side.]]
45** Later, she finds out that the vampires have started to kill some people they were keeping as a herd; she shows up at their HQ in full on poltergeist mode, ripping doors out of their hinges and sending multiple vampires flying into walls hard enough to be knocked out.
46** Werewolves in general seem to be this in ''Being Human'', especially George and Tom. Both really nice, friendly guys, but George rips Herrick to shreds, and Tom has spent his entire life being taught how to hunt and kill vampires.
47* Bernadette in ''Series/TheBigBangTheory''. Don't piss her off, she has access to weaponized smallpox. She also accidentally once crossed the common cold with the Ebola virus. Of course she wouldn't admit something like that because that would be very bad.
48* ''Series/TheBill'': PC Honey Harman to be very specific. She can be very nice to members of the met. However, she can take down criminals with her impressive judo moves if they mess with her.
49* ''Series/BlakesSeven'': Vila Restal is a [[ObfuscatingStupidity cowardly drunken safecracker]] who drops a Federation officer with one punch after [[spoiler:she shoots Dayna.]]
50* ''Series/BlueBloods'' Police Commissioner Frank Reagen hardly ever raises his voice, and for the most part his days of tossing and cuffing perps are long behind him. He's still capable of dealing out .38 caliber death to anyone who threatens his family. An unrepentant serial [[spoiler: rapist who attacks Erin]] learns this the brain-splattery way.
51* ''{{Series/Bones}}'':
52** Jack Hodgins can be a nice, decent guy with his friends, but he does struggle with anger issues and when serial killer Christopher Pelant taunts him, Hodgins nearly chokes him to death.
53** Booth too. He’s usually a nice, fairly likable guy with a fun sense of humor, but he is a trained sniper and Army ranger… mess with his family and you’ll get a world of hurt.
54* ''Series/BreakingBad'': There's quite a couple of AffablyEvil characters in the show that turn out to be capable of extreme violence. But probably no character exemplifies this trope like Todd from Season 5. He's a quiet and seemingly rather shy guy who is always nice and apologizes a lot, but the entire new drug operation starts to turn into a disaster when [[spoiler:he pulls a gun after stealing chemicals from a train to shot a 14-year-old boy who saw them]]. He then arranges for [[spoiler:the murder of Gus' nine henchmen in prison through his uncle's gang]] and finally stops his uncle from executing Jesse [[spoiler:because he first wants to torture him to learn what he told the DEA]]. He even seems nice when helping Jesse to get up and walk [[spoiler:to his next torture session]].
55* Achim in ''Series/{{Brummkreisel}}'' is a downplayed example. He's very patient with Kunibert but if he's pushed too far he'll get back at him in a not-too-threatening way or sternly reprimand him.
56* ''Series/BuffyTheVampireSlayer'':
57** Buffy herself is very sweet and friendly but there is a reason vampires and demons are so afraid of her.
58** Willow full stop. After Riley gets her to help court Buffy she threatens to beat him to death with a shovel if he hurts her. This was after she wanted to ax murder Parker when he hurt Buffy. When Glory messes with her girlfriend she tries her very best to ''kill'' the attacker. This culminates into becoming Season 6's BigBad after [[spoiler: Tara's murder]]. [[spoiler:Warren, Tara's killer,]] gets ''flayed'' after she did some ColdBloodedTorture on him. This transformation is foreshadowed a number of times: in the Season 3 episode "Doppelgangland": the vampire version of Willow is sadistic; vampire personalities reflect the human's inner selves, with no soul.
59** Ex-demon Anya says, "Well, those are the ones you have to watch out for the most. Responsible types. (...) Responsible people are always so concerned about being good all the time that when they finally get a taste of being bad, they can't get enough."
60** Tara may never have used a weapon before, but when a demon is trying to choke Willow, she will kill it. With a single strike. She later manages to shout down Anya.
61** Dawn can be scary if she wants, threatening Spike that if he does anything to her sister, he will wake up on fire one day. Spike is even scared. Poor Xander found this out the hard way when he was following Buffy's instructions to get Dawn out of town before the final throwdown with the First Evil. Dawn doesn't even wait to finish Buffy's note after she wakes up before reaching for her taser, zapping Xander, and turning the car around.
62** Quiet, stuttering, somewhat bumbling Giles efficiently beats the crap out of [[spoiler:Ethan Rayne]], then kicks him to get information. He goes after [[spoiler:Angel]] with a flaming bat. He stabs [[spoiler:the mayor]] in the chest with a sword. He delays Buffy so [[spoiler:Principal Wood]] can beat [[spoiler:Spike]] to death with his bare hands. He physically and professionally threatened Principal Snyder into readmitting Buffy back into Sunnydale High. He really proves it in Season 5. First, when a recalcitrant servant of the BigBad refuses to talk, he tells the girls to get some rope; the camera follows them and we hear a noise; whip pan back to a now very talkative demon. He manhandled Spike while ordering him to get over his obsession with Buffy and move on. In "[[Recap/BuffyTheVampireSlayerS5E22TheGift The Gift]]", he [[spoiler:suffocates innocent and long-suffering Ben]] in order to kill Glory. Now we know why, Giles used to go by the name Ripper.
63** Xander is always helpful and brave, but being non-superpowered, is not a formidable hand-to-hand fighter. Demons and vamps typically don't have to worry too much about him. But if you mess with someone he loves, you'll find yourself on the wrong end of his berserker rage. In "[[Recap/BuffyTheVampireSlayerS1E6ThePack The Pack]]" he is released from his hyena curse and the first thing he sees is the crazed zoo-keeper attacking Willow. Xander attacks and strikes first, with Buffy finishing the job. Despite previously stating that he hides until danger leaves when backed into a corner while protecting Buffy [[spoiler:he threatens Angelus, one of the most dangerous vampires in history, and warns that he will be there to see him staked. Angelus actually takes him seriously and leaves.]] In "[[Recap/BuffyTheVampireSlayerS4E10Hush Hush]]" Xander sees a bloody jowled Spike leaning over a napping Anya, his point of view suggesting that Spike had attacked her. Xander immediately launches a what-should-be-a-suicidal-attack-against-what-he-thinks-is-a-restored-vampire and starts pounding Spike. In "[[Recap/BuffyTheVampireSlayerS5E22TheGift The Gift]]", [[DidYouJustPunchOutCthulhu he sucker-punches an evil goddess]] ''[[MugglesDoItBetter with a wrecking ball]]''. After [[spoiler:Willow is kidnapped in "[[Recap/BuffyTheVampireSlayerS2E1WhenSheWasBad When She Was Bad]]"]], to Buffy: "If Willow dies, I will kill you."
64** Joyce. She humiliated Snyder in his attempts to keep Buffy out of school, looked Faith in the eye and called her psychotic, and took a swing at Spike with an axe.
65%%** The Mayor.
66* Leo of ''Series/{{Charmed|1998}}''. He is a peaceful healer who often gives words of advice to the Charmed Ones. But people forget that he was a medic during UsefulNotes/WorldWarII and if anyone threatens Piper or his sons, he will kill. He has killed an Elder and even helped a magical group wipe out free will.
67* Aunt Hilda in ''Series/ChillingAdventuresOfSabrina'' is the nicest, kindest, cuddliest, and most of all the least threatening character on the entire show. That's because she leaves the making threats to her sister; she just carries them out. Exemplified in the scene in which she calls her sister's rival in for what looks to be a friendly chat, apologetically explains that she doesn't like her sister being antagonised, and then throws in that oh, by the way, [[spoiler:those cookies you've been eating are loaded with cyanide.]]
68* ''Series/{{Chuck}}'':
69** Chuck seems harmless, friendly, dorky, and charming, but if you threaten his friends or family, expect him to destroy you.
70** His sister Ellie usually wants to run from a fight, but if Chuck is in trouble, she quickly delivers the violence. She decisively ambushes Casey with a frying pan, mistakenly thinking he's evil. She clubs Daniel Shaw, one of the shows most dangerous villains, in the same style. She drives her car into another car to incapacitate Evil!Sarah.
71** Ellie's husband Devon is affable to the point of pacifism, blanching at the idea of holding a gun. But when a CIA guard needs to be dropped in order to save Sarah, Devon makes with the fist.
72* ''Series/{{Community}}'':
73** Annie is adorable, yes, but don't you dare eat her beans. Or steal her pen.
74** Shirley's a good Christian woman, but don't let that make you think she won't mess you up in paintball. And not just in paintball -- "that thing about the jukebox was way too specific to be improvised."
75** And don't piss either of them off if they happen to be temporary campus security guards, as Jeff learned when their interrogation of him ended with Annie slamming his head against a table and Shirley threatening to cut him up with a pizza slicer.
76* ''Series/CovertAffairs'': Auggie is a good example of this trope. He's a sweetheart most of the time, but he has some unresolved anger issues that can occasionally make him violent. In the past three seasons, he's...
77** ...attacked (and almost killed) the man responsible for his blindness and the death of his friends,
78** ...started a bar fight and smashed a beer bottle over a stranger's head,
79** ...punched Arthur Campbell in the face,
80** ...and got himself temporarily kicked out of Langley after he put Henry Wilcox in a chokehold.
81* ''Series/CriminalMinds'': Jennifer "JJ" Jareau. Cute, tiny, blonde. Will shoot you dead if you go after her [[TrueCompanions team]], and [[MamaBear god help you if you go after her son or husband]].
82** Her best friends and teammates Reid and Garcia too. The latter is a [[TheHeart bubbly]], pacifist, and civilian [[AwesomeByAnalysis tech analyst]] who will destroy your life with a few clicks of her [[PlayfulHacker keyboard]] if you piss her off. The former is an adorable, [[NiceGuy kind-hearted]] former [[ChildProdigy child prodigy]] who uses his [[BadassBookworm genius]] [[TheSmartGuy intellect]] to track and outsmart serial killers, child rapists, assassins, and various other nasty people, has straight up talked various dangerous people out of killing him and [[TalkingTheMonsterToDeath screwing themselves over]] and has a knack for giving some very effective [[ReasonYouSuckSpeech Reason You Suck Speeches]]. He’s also learnt to be pretty handy with a gun. Essentially no matter how bad the situation is for Reid it’ll eventually end up worse for whoever’s crossed him.
83* ''Series/{{CSI}}'': D.B. Russell. He's normally kind of laid back, rather quirky, and has a weird sense of humor sometimes, but when former undersheriff [=McKeen=] got his granddaughter kidnapped, he got out his gun and was on the edge of taking the kidnappers out himself. Brass had to rein him in a couple of times during the search.
84* ''Series/{{CSINY}}'': This has been said about Lindsay Messer, from some of her conversations with Danny. One was about how she'd make him look like a domestic abuser and another was about how she'd haunt him if she died before him. [[MamaBear There's also her protectiveness of her family.]]
85* It's not advised to keep harping on the nice ones in ''Series/CutthroatKitchen''. Piss them off enough and they ''will'' hit you with all the sabotages in the game.
86* In ''Series/TheDarkCrystalAgeOfResistance'', the friendly and chipper Deet harnesses the power of the Darkening to absolutely annihilate skekLach.
87* ''{{Series/Deadwood}}'': Seth Bullock runs up against the edge of "nice" (mixing this trope with HairTriggerTemper) but in general he's an honorable, hard-working, polite man who helps out troubled widows, acts as law keeper for Deadwood, and [[BreadEggsMilkSquick always arranges a proper funeral for people who've tried to kill him]]. But push him a little too far — mess with his friends, or call him out on [[spoiler:his extramarital affair]] — and you'll find out why his temper is considered literally ''psychotic'' even by cold-blooded murderers, often coming close to killing the offending party with his bare hands.
88* ''Series/{{Dexter}}'': [[Characters/DexterDexterMorgan Dexter Morgan]] is quite affable for a serial murderer. Just '''''don't''''' push ''any'' of his {{berserk button}}s.
89* ''Series/DiagnosisMurder'': Kindly, avuncular Doctor Sloan will try to save the life of a man who held him at gunpoint... but if you hurt his son, he will kick you down a flight of cement stairs. His son Steve is less gentle-natured, but still a nice guy; he's also Homicide Lieutenant Steve Sloan, and if you threaten his best friend, he will refuse to kill you so that you can die a slow, lingering death from Huntington's Chorea. Threaten that friend along with his father and he'll deliberately expose you to the same disease you exposed them to and threaten to withhold the cure.
90* ''Series/DoctorWho'':
91** The Doctor is this trope breathing. The exact specifics vary a bit during the many incarnations of the character and series.
92*** Don't think it doesn't go back to the earliest days: The First Doctor was, after a bit of CharacterDevelopment, the most affable gentleman you could hope to meet. But as stories such as [[Recap/DoctorWhoS1E7TheSensorites "The Sensorites"]] and [[Recap/DoctorWhoS2E2TheDalekInvasionOfEarth "The Dalek Invasion of Earth"]] show, when he draws a line, only a very great fool would dare to push him.
93*** The Second Doctor is a [[BewareTheSillyOnes distinctly odd]] but usually friendly space hobo who will go for a peaceful solution when possible, such as [[Recap/DoctorWhoS4E8TheFacelessOnes negotiating a settlement with the Faceless Ones after relatively minimal casualties]]. However, when you pushed too far, the recorder-playing and hat envy would just dry up, and if you were ''lucky'', you might survive what came next.
94---->'''Ice Warrior:''' You have destroyed our entire fleet!\
95'''Two:''' [[TranquilFury You tried to destroy an entire world.]]
96*** The Fourth Doctor is a [[CloudCuckoolander quirky]] and [[AwesomeEgo arrogant]] but generally affable fellow whose standard greeting is to brandish a bag of jelly babies under the other person's nose and ask if they'd like one, and who generally offers even the most reprehensible alien a fair opportunity to negotiate or back down. In [[Recap/DoctorWhoS13E5TheBrainOfMorbius "The Brain of Morbius"]] he kills Morbius's pet MadScientist with ''cyanide gas'', and in [[Recap/DoctorWhoS12E4GenesisOfTheDaleks "Genesis of the Daleks"]] one of his gambits is to hold down the off button on Davros's life support until he orders that the first Daleks be destroyed.
97*** In [[Recap/DoctorWhoS19E6Earthshock "Earthshock"]], the Fifth Doctor spends much of the story trying to talk the Cyberleader out of destroying the Earth, but then when that fails... he attacks him with Adric's gold-edged badge, then shoots him. Twelve times. Just to be sure. Five, generally the most polite and down-to-earth Doctor, was also the one who [[BatmanGrabsAGun had the least of a hangup about using guns]], even blowing smoke off a pistol after shooting an uncased Dalek in [[Recap/DoctorWhoS21E4ResurrectionOfTheDaleks "Resurrection of the Daleks"]].
98*** The Tenth Doctor is, for the most part, a cheerful, bubbly and fun-loving character — unless, of course, you happen to ''really'' piss him off, in which case he'll incinerate and drown your (overgrown spider) children ([[Recap/DoctorWho2006CSTheRunawayBride "The Runaway Bride"]]) or make you immortal and subject you to a [[FateWorseThanDeath horrific eternal prison from which there is no escape]] ([[Recap/DoctorWhoS29E9TheFamilyOfBlood "The Family of Blood"]]), amongst others. "No second chances", indeed.
99*** From "The Family of Blood":
100---->'''Son of Mine''': [[TranquilFury He never raised his voice. That was the worst thing — the fury of the Time Lord]] — and then we discovered why. Why this Doctor, who had fought with gods and demons, why he had run away from us and hidden. He was being kind. He wrapped my father in unbreakable chains forged in the heart of a dwarf star. He tricked my mother into the event horizon of a collapsing galaxy to be imprisoned there, forever. He still visits my sister, once a year, every year. I wonder if one day he might forgive her, but there she is. Can you see? He trapped her inside a mirror. Every mirror. If ever you look at your reflection and see something move behind you just for a second, that's her. That's always her. As for me, I was suspended in time and the Doctor put me to work standing over the fields of England, as their protector. We wanted to live forever. So the Doctor made sure we did.
101*** Whenever one of his companions is threatened, you can bet that the Doctor will unleash some serious hurt.
102*** Lampshaded in [[Recap/DoctorWhoS30E9ForestOfTheDead "Forest of the Dead"]] when the Doctor gives the villains an ultimatum to leave him alone or suffer. The villains, after realising just who the Doctor ''is'', immediately back down and let him do whatever he wants.
103---->"Don't play games with me. You just killed someone I liked. 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."
104*** The Tenth Doctor hits an all-new level at the end of [[Recap/DoctorWhoS30E16TheWatersOfMars "The Waters of Mars"]]. After getting tired of everyone dying around him, [[spoiler: he decides to throw away the laws of time, declares himself the "Time Lord Victorious" in a speech that makes his attitude in "The Runaway Bride" look sane, and saves a woman who was supposed to die. When confronted with his darker side, she kills herself in order to stop him.]]
105*** In a number of episodes, the Doctor has at least attempted to simply announce who he is, expecting the villains to run away simply based on his reputation. Sometimes it worked.
106*** [[Recap/DoctorWhoS31E5FleshAndStone "Flesh and Stone"]]: When the Weeping Angels mock the Eleventh Doctor and kill a perfectly innocent man, he gives them a BadassBoast, and when they don't listen, he proceeds to ''erase them from time''.
107*** One episode makes this part of its title: [[Recap/DoctorWhoS32E7AGoodManGoesToWar "A Good Man Goes to War"]]. Turns out it's part of a saying in-universe that the villains have much reason to consider: "Demons run when a good man goes to war."
108*** And in the actual ''content'' of that episode, the Doctor raises an army of hundreds of beings he's helped out in the past to take on an army who have kidnapped one of his companions [[spoiler: to steal her baby to raise as a weapon against him]]. Though, the Doctor himself might argue that the last two words of this trope don't apply to him:
109---->"Good men don't need rules. Today is not the day to find out why I have '''so many.'''"
110*** Rory and the Doctor's [[https://www.youtube.com/watch?v=4I-efBSAUiY message to the Twelfth Cyber-Legion]].
111*** And some [[https://www.youtube.com/watch?v=zKr7uuDMkns good examples]] of the Doctor's darker side...
112*** The Twelfth Doctor is one of the DarkerAndEdgier incarnations, and ''fiercely'' protective of Clara Oswald. Naturally, the villains of the three-part finale of Series 9 dare to put Twelve through the wringer: The process starts in [[Recap/DoctorWhoS35E10FaceTheRaven "Face the Raven"]] with [[spoiler:his betrayal by Ashildr and '''Clara's death''']], and continues in [[Recap/DoctorWhoS35E11HeavenSent "Heaven Sent"]], in which [[spoiler: he is imprisoned in a mobile castle and faces either death or insanity]]. It culminates in the events of [[Recap/DoctorWhoS35E12HellBent "Hell Bent"]], in which he's at the DespairEventHorizon and acting purely out of rage and self-interest, and not even Clara can stop him...
113*** The Daleks, a race of aliens genetically engineered to be nothing but pure hatred, completely devoid of mercy, pity, or remorse, serve as one of The Doctor's series-long arch-nemeses. There are billions of them and only one of him, and while they may not exactly fear him as such (since they're incapable of it), they certainly have a healthy respect for just how dangerous he is to them. They refer to the Doctor as "[[NamesToRunAwayFromVeryFast The Oncoming Storm]]" and "[[AlwaysABiggerFish The Predator of the Daleks]]".
114*** The War Doctor, the forgotten incarnation of the Doctor who fought in the Last Great Time War. When the Daleks notice he's arrived on the field of battle, they immediately begin freaking out.
115*** The Thirteenth Doctor, [[ContrastingReplacementCharacter contrasting the generally antisocial Twelve]], is one of the most openly friendly versions, with the largest team of companions and a tendency to be extremely talkative and often quite a bit childish. Her career included stuffing [[AliensAreBastards a particularly bastardly alien]] full of his own DNA bombs before he set them off and stopping a WorldWreckingWave by grabbing a character who could absorb a virtually infinite amount of energy and hucking him out of the TARDIS and straight into it.
116** Barbara Wright (later Barbara Chesterton). She's caring — and will commandeer a truck and mow down Dalek guards with it to get to her TrueCompanions!
117** Ian Chesterton is an affable 1960s science teacher who functions as TheHeart and spends most of his time looking after the others. He is also a terrifyingly gifted swordfighter and even capable of threatening ''the Doctor'' into submission when he has to.
118** Nero's major-domo Tavius in "[[Recap/DoctorWhoS2E4TheRomans The Romans]]" is a kind-hearted FriendToAllLivingThings — who is involved in a plot to kill Nero.
119** Sarah Jane Smith, on both the main series and ''Series/TheSarahJaneAdventures'': a kind, compassionate TechnicalPacifist who will utterly ''destroy'' you if you try to invade her planet, hurt [[TrueCompanions her friends]] or mess with her son.
120*** In later series it becomes clear that Luke has inherited this from her. Don't try to isolate him and lock his friends up in horrible nightmares, and never trap his mum in a painting!
121** Professor Chronotis in [[Recap/DoctorWhoS17E6Shada "Shada"]] is repeatedly described by the other characters as "such a nice old man" — and he is, with a bit of old-man irascibility to balance it out. In reality, he's a Time Lord outlaw possessing the unique psychic ability to forcibly rewrite other people's personalities with his own, and likely also a CharmPerson. In the final moments of the story, the Doctor wonders to Romana that maybe someday people will look at him and describe him as "such a nice old man".
122** Which companion would you expect to hold ''the Lord President of Gallifrey'' at gunpoint? Probably not Nyssa!
123** Rose Tyler is a very nice, very normal 19-year-old Londoner. She also happens to be in love with the Doctor. When the Doctor is facing the Dalek fleet and tries to save Rose by sending her and the TARDIS back to 2005, she loses it and attempts to break into the TARDIS' central console. When she eventually does, she [[spoiler: absorbs the entire Time Vortex to become the living embodiment of the TARDIS and travels to the future to destroy the Dalek fleet and resurrect Jack.]] Later, she even brags about it to The Cult of Skaro.
124** Captain Jack Harkness of ''Doctor Who'' and ''Series/{{Torchwood}}''. Normally cheerful, flirty, and friendly. Hurt his team and he will do something horrible to you. Such as shoot you repeatedly with a pump-action shotgun. In the knee caps.
125*** Even though he's immortal, do NOT try to hurt Jack in any way. You don't want to find out what the usually soft-spoken, calm, and very loyal Ianto Jones will do to defend the man he loves.
126** Wilfred Mott is a kindly old man who you just want to give a hug. But when the Earth [[Recap/DoctorWhoS30E12TheStolenEarth is stolen]], he promptly arms himself with a cricket bat against the "green swine", and later ''shoots a Dalek in the eyestalk with a paintball gun''. And ''lives'', thanks to some timely help.
127** Amy Pond, who fits ViolentlyProtectiveGirlfriend to perfection. Mess with Rory, and she will not hesitate to crush you. In [[Recap/DoctorWhoS32E13TheWeddingOfRiverSong "The Wedding of River Song"]], when the Silence are preparing to kill Rory mid-HeroicSacrifice (in an alternate timeline), taunting him that Amy will never come back, she remembers who he is to her and does indeed come back. With a fully loaded G-36 assault rifle. And opens fire, killing all of the Silence on the spot. Then, when Madame Kovarian begs Amy to save her from her malfunctioning eyedrive:
128--->'''Amy:''' You took my baby from me, and hurt her, and now she's all grown up and she's fine, but I'll never see my baby again.\
129'''Kovarian:''' But you'll still save me though. Because ''he'' would, and you'd never do anything to disappoint your precious Doctor.\
130'''Amy:''' The Doctor is very precious to me, you're right. But do you know what else he is, Madame Kovarian? Not here. ''[reattaches eyedrive]'' River Song didn't get all of it from you, ''sweetie''.
131** River Song plays with this trope. Every time we see her on camera she's very "Hello, Sweetie!" and [[LovesSecrecy playfully teasing the Doctor in an "I know something you don't know" kind of way]]. However, when a Dalek assumes, as a companion, she'll be compassionate and merciful, she simply states, "I'm River Song. Check your records again." It then proceeds to ''beg for mercy.''
132** Rory Williams, who started out a nice fellow and a good nurse, and then got turned into an [[spoiler: Auton with all of Rory's memories... and love for Amy]]. He guarded the Pandorica for two thousand years and then went hand-to-eyestalk with a Dalek that was threatening the Pandorica (and therefore Amy) with one question: "Where. is. my. wife?!" The Dalek didn't come out of that one on top. And a note to any Cybermen reading this: '''''DON'T''''' make him repeat the question!
133*** A friendly reminder: Rory has [[Recap/DoctorWhoS31E13TheBigBang spent just a little under 2000 years guarding the Pandorica]]. And even though they pushed the Big Damn ResetButton, ''he remembers everything''. Apparently it's not all sunshine and flowers.
134*** Rory kept wearing his eye-drive long after it activated just so he could fight the Silence effectively and protect Amy, who (due to a TimeyWimeyBall) didn't even know who he was.
135*** On top of that, who do you think the "Good Man" in [[Recap/DoctorWhoS32E7AGoodManGoesToWar "A Good Man Goes to War"]] actually referred to? Hint: The Doctor flat-out stated that it's not him!
136** Brigadier Alistair Gordon Lethbridge-Stewart. A somewhat old-fashioned but generally polite and reserved officer, even the most frustrating antics of the Doctor could rarely put him past [[DeadpanSnarker dry commentary]]. But make no mistake: TheBrigadier is here to make sure that what he thinks needs to be done gets done, and if that requires [[Recap/DoctorWhoS7E2DoctorWhoAndTheSilurians blowing up an entire underground city]] or [[Recap/DoctorWho20thASTheFiveDoctors sucker-punching the Master]], well, someone's got to. ''Dying of old age'' did not stop him; when resurrected as a Cyberman in [[Recap/DoctorWhoS34E12DeathInHeaven "Death in Heaven"]], he [[HeroicWillpower shakes off the control]], rescues his daughter from being thrown out of a plane, and ''shot Missy for throwing her out of it'' ([[JokerImmunity it doesn't work in the long term]], but points for trying).
137* ''Series/DrakeAndJosh'': Josh Nichols is the series ButtMonkey, but very decent and caring. But give him an authority of power like a teacher and see [[SadistTeacher what he can become]], as Megan learned. In another episode, when Drake makes him miss his important chemistry exam, [[UnstoppableRage Josh angrily tries to beat him up on the spot]].
138-->'''Josh:''' ''(points at Drake)'' [[YouExclamation You!]]\
139'''Drake:''' [[DefensiveWhat What?]]\
140'''Josh:''' Raaaaaaaaaaah! Come here! Come here, you wanna tussle!
141* ''{{Series/Emergency}}'':
142** Dr. Brackett is an experienced emergency-room doctor with a very thick skin, but if you get under it, ''watch out''. In one episode an angry "Hell's Angel" type motorcycle dude with a bad cut on his head gets in a heated argument with Dixie. Brackett hears the shouting, walks into the exam room, and gets punched by the angry biker. He promptly gets up and decks the guy with one punch of his own, after which the biker lets Brackett examine his badly cut forehead without another word.
143** Paramedic Roy [=DeSoto=] can fall into this at times. He's normally pretty easy to work with and get along with, but he won't hesitate to call someone out if they do something that seriously breaks procedure or worse, endangers a patient. The main case is a CombatMedic who thinks his battlefield training makes him better than Roy and John. Roy never actually yells, but he gives the guy a serious talking to, with a tone and expression that makes it clear that it's one of his angriest moments of the series. Not that it does much good.
144* ''Series/FamilyMatters'': A pre-Urkel episode titled "False Arrest" features Ron Glass as Buddy Goodrich, the star of an eponymously titled show that [[AffectionateParody is an obvious parody of]] ''Series/DiffrentStrokes'' (with Goodrich playing a wealthy black banker who adopts two poor white boys). On-screen, Goodrich plays the wise, genial father; off the set, Goodrich has a huge ego and is a jerk toward his castmates and others he works with. When Carl goes to the studio to procure tickets to the show, he nicely informs Goodrich that he's parked in a fire zone and needs to move his car, but Goodrich, believing he can park anywhere he pleases because he's Buddy Goodrich, refuses, prompting an argument; when Goodrich's ego gets the best of him, he takes a swing at Carl, prompting his arrest. Goodrich tries to use his charms to rally the other Winslows to his side, but the truth comes out and it becomes obvious he's just a jerk unworthy of their respect.
145* Zhaan of ''Series/{{Farscape}}'' is by far the most compassionate and level-headed member of the cast, and usually exudes a Zen master level of calm. But it's revealed halfway through the first season that she was a very violent person in the past, and even after she attained inner peace, every once in a while she loses her temper, showing a cold fury that is much creepier than any of the others outbursts.
146-->'''Zhaan:''' Is this the way you repay my help? How would you like your arm torn off? Hear me! I could rip you apart! Right now, Kahalan help me, I'd enjoy it.
147** Likewise, Pilot is a shy and gentle creature dedicated to serving the crew of Moya, regardless of how much they exploit or abuse him. However, on quite a few occasions, the crew or unwanted visitors have found out the hard way that pissing off the guy that controls the life support systems ''might'' just be a bad idea. Case in point: the terrorist he flushed out of an airlock while laughing maniacally.
148** While burying Moya's son, they are attacked by an insane Leviathan for carrying other life forms. Dargo is out in his small gunship, preparing to blow it away, but everyone is worried Pilot and Moya will be upset if they kill the attacking Leviathan. Then Moya informs Pilot [[spoiler: that the insane leviathan starved her own Pilot to death]], and Pilot has two words to say on the whole situation:
149--->'''Pilot''': [[spoiler:'''KILL HER!''']]
150* ''Series/{{Firefly}}'':
151** Why is the [[RetiredBadass older, fatherly preacher]] as good a shot as the hardened mercenary Jayne when he chooses to fight?
152*** While the Bible is very clear on the subject of killing it is somewhat "fuzzy" about kneecaps.
153** River Tam, despite her outbursts of occasional [[AxeCrazy madness]], is generally a gentle and friendly soul who finds violence terrifying. [[ManchurianAgent Then the Fruity-Oaty Bars commercial comes on,]] [[SuperSoldier and,]] [[WaifFu well....]]
154** When Simon gets hurt, [[ViolentlyProtectiveGirlfriend River kicks]] [[TranquilFury Reaver ass.]]
155** River's brother, Simon, is generally meek, polite (if [[DeadpanSnarker snarky]]) and occasionally clumsy guy who apparently wouldn't hurt a fly... mess with his sister though and you'll find that he not only throws a mean punch but can also get [[DeadlyDoctor devilishly creative with his medical inventory.]] And it’s probably safe to include Kaylee and their kids as people you don’t want to threaten as well later on in the comics.
156** Kaylee is a total [[TheCutie sweetheart]] who is [[TheHeart loved]] by pretty much everyone. While she isn’t great around violence, she doesn’t even [[NervesOfSteel flinch]] at [[BadassAdorable defusing a boobytrapped bomb]].
157* Doctor Parker, from ''Series/FlandersCompany'', is a very nice fellow, always calm and collected, happy to help his company and others in general... [[spoiler:Until his SuperPoweredEvilSide takes control. Expect a lot of slaughters and massive quantity of blood.]]
158* The titular character of ''Series/TheFlash2014'' is generally a pretty nice and dorky guy, and an AllLovingHero who likes goofing off with his friends and family... but he is also one of the most dangerous and powerful people on his entire world, and if you press his RelativeButton, you ''will'' regret it.
159* ''Series/GameOfThrones'':
160** Daenerys Targaeryn may seem like a young, helpless girl and is one of the kinder people on the show, displaying particular compassion for the weak and helpless. Once you've crossed her though, there is no coming back. And you should probably get ready to die in some horrific fashion.
161*** If you go after her husband or her child, she will burn you alive. After Mirri Maz Duur successfully manages to kill her husband and son, Daenerys has her tied to Khal Drogo's funeral pyre. Mirri Maz Duur claims that she won't scream for Daenerys. She is so wrong. Daenerys has taken Mirri's earlier statement that "only death can pay for life" to heart, and is using Mirri's death to serve a cause greater than just revenge.
162*** After Pyat Pree tries to imprison her along with her dragons in the House of the Undying, she has them ''flambé him alive'', then proceeds to seal Xaro and Doreah in his own empty treasure vault for betraying her.
163*** Kraznys mo Nakloz repeatedly insults her while hiding behind what he thinks is the language barrier and is an amoral slaver on top of that. So she has him immolated on the spot during the battle of Astapor. And there was much rejoicing.
164*** As of the sacking of Astapor, Dany has killed more named characters than any ''two'' other people on the show.
165*** She rewards the same number of Good Masters in Meereen with the same agonizingly slow death that they gave one hundred and sixty-three slave children. By nailing them to posts to die of dehydration and exposure. Yikes.
166*** She has both a freedmen and a master executed; for defying her in the former and merely being suspect in founding the Harpy's Sons in the latter! Said master was later found out to be innocent of that particular crime and Dany has him seared to a crisp by Rhaegal before he and his brother rip the poor bastard in two!
167*** When standing in judgement before all the gathered Dothraki khals, the warlords all decide to make her wish she was never born. Dany doesn't think much of this and annihilates them in an inferno which she, the little arsonist, starts personally... with her standing resolute at ground zero.
168** Arya is sweet and nice at the beginning of the series but learns to take vengeance dead seriously. When Jaqen offers to kill three people for her, she takes him up on his offer.
169** At first glance, Varys is an effeminate, benevolent sycophant, but the reality is very different. It takes serious balls (so to speak) for Varys to pull off his manipulations the way he does. He traps the sorcerer who castrated him as a child in a box after stitching up his mouth, and even straight-up disagrees with Joffrey. It may sound like a small thing, but Pycelle would never have the guts, nor Littlefinger the moral standards, to do such a thing.
170** Although always gentle and now frail with age, Maester Aemon shows just a touch of the Targaryens' fiery temperament when he recalls the downfall of his family to Jon in Season 1.
171** Subverted by Hodor, who is such a GentleGiant that even being baited with spears does not provoke him. He only uses violence when Bran hijacks his body and forces him to do it against his will.
172** Jon is probably one of the nicest people in this entire screwed up world. The gods help you if you harm any of his beloved half-siblings or Sam, or if you push him too far, as Karl, Janos Slynt, and Ramsay found out.
173** Arya at one point encounters a prisoner transport with three men in cages. One is a rapist and serial killer. One is a cannibal who doesn't speak but tries to bite anyone who comes near. The third is a bland-looking, quiet, polite, and soft-spoken man... who reduces the guards, the rapist, and the cannibal to whimpering wrecks with a glance. Ladies and gentlemen, meet Jaqen H'qar, Faceless Man.
174** House Reed is modest and reclusive, reflected in the members we've seen, but utterly fierce defenders of their territory and the North's first line of defence against southern invasion. In the books, their enemies call them all manner of disparaging nicknames for their "dishonourable" tactics and humble lifestyle, but among such monikers is ''Bog Devils''.
175** Characters we've met who belong to House Mormont are all benevolent people but are extremely ferocious if pushed too far.
176** Kevan Lannister is considerably more mild-mannered than Tywin but he can hold his own in tirades and has actually schooled Cersei when she assumed him as a YesMan.
177** When Barristan Selmy hands in his resignation and rages that he ''"shall die a knight"'', throwing aside his cloak and armour, Littlefinger sneeringly quips Selmy will be ''"a naked knight, apparently"'', prompting snide laughter from the rest of the court... which abruptly ends the second Selmy rips his sword from its scabbard and threatens to take on the rest of the Kingsguard singlehandedly, reminding everyone that it's not a good idea to make fun of a man who's considered the greatest fighter in recent history and now has nothing left to lose. Littlefinger's expression in particular screams an indication that it might have been better to keep his mouth shut.
178* ''Series/GenV'': Cate Dunlap is generally a nice person, but when she hears Rufus making fun of [[spoiler: her boyfriend's death]] in "God U." she [[MindRape tells him]] to buy a [[BatterUp Louisville Slugger]] and hit himself in the balls with it every hour on the hour while shouting, "Film/{{Jumanji}}!" Later, when rescuing Andre from some Vought security guards, her way of doing so is by compelling the male guard to perform oral sex on his female partner's flashlight, and then [[AssShove shove it up his ass]] afterward (which isn't shown onscreen).
179* ''Series/GetSmart'': KAOS has created an evil robot and CONTROL's robot, Hymie, must stop him. Hymie decides he wants to be nice and tries to make friends with the enemy robot. It does not work and the evil robot finally goes too far. At that point Hymie notes, "Hey! Nice is nice, but enough is enough!" and fights the robot and defeats it with the help of Maxwell Smart.
180* Will and Finn on ''Series/{{Glee}}'' are the epitome of {{Nice Guy}}s. The two spend the first half of Season 1 in TheBabyTrap by their women and when they find out...whoo boy. Will goes borderline psychotic upon realizing his wife's fake pregnancy and it almost appears like he is going to hurt ''her''. Finn meanwhile finds out his girlfriend's baby is really his best friend's and the second he hears it runs after him, attacks him, and proceeds to beat the living daylights out of him, be held back by several football players, and manages to chuck a chair on his way out.
181** Not to mention Burt Hummel, a {{Good Parent|s}} and NiceGuy, who chases Dave Karofsky down in the school hallway, pins him up against the wall and is about an inch away from beating him senseless after he finds out that Karofsky threatened to kill Kurt. And this just five episodes after a serious heart attack and coma. If you know what's good for you, you do ''not'' threaten Burt's son.
182** And then, let's not mention what the reaction of our group of misfits were when Rachel was egged by her ex-boyfriend and his rival glee team. The moral? Don't mess with [[TrueCompanions New Directions]].
183*** They have a very similar reaction when Blaine gets hit by a [[EyeScream rock salt-filled slushie]] by Sebastian, his StalkerWithACrush and put into the hospital. All of them look ready to go start a fistfight, and Mike even says that they want an eye for an eye. They're ''very'' protective of their own.
184* Betty White's character Rose of ''Series/TheGoldenGirls'' fame, is the sweetest, most bubbly member of the foursome, if also the dimmest. But there is a very, ''very'' good reason why the others take great pains not to get on her bad side...
185* ''Series/GossipGirl'':
186** Dan, whose conversion as an Ultimate Insider in Season 3 is in full bloom in Season 4. It was either "adapt or die". Usually, something happens to remind him that he has a moral compass before he goes off the deep end.
187* ''Series/{{Grimm}}'': Monroe is a bookish, awkward watchmaker / clock repairman with a passion for Old Europe, cooking, wine, and the finer things in life... and a werewolf who could -- and sometimes does -- tear people apart. Nick is a genuinely good cop who will leave you alone if you haven't done anything illegal, no matter who or what you are... but he will smash your face with a warhammer if you threaten his friends or family. Juliette, a veterinarian and thus a friend of all living things, but when an ogre breaks into her home she doesn't hesitate to throw a pan of boiling water in his face, and when her friend is being abused by her husband she beats the cr@p out of him using common kitchen utensils ([[spoiler:taken up a notch once she becomes a Hexenbiest]]). Indeed, it is hard to think of any of the regulars or semi-regulars who ''don't'' fit this trope to a greater or lesser extent! Even the meek Fuchsbau Rosalee; you do NOT want to mess with her husband, or she'll literally tear your throat out, even if you're a big mean Blutbad.
188* Paladin of ''Series/HaveGunWillTravel'' is generally a fairly friendly guy, and even gentle to nice people, but can be a terrible enemy if you cross him/hurt innocents.
189* In ''Series/HawaiiFive0'' (the new one) Steve is usually the crazy one who breaks a lot of laws while interrogating suspects, whilst Danny chastises him. However, if you hurt or threaten anyone Danny loves, especially his daughter... you might start to wish you'd never been born.
190* ''Series/{{Heroes}}'' Happy-go-lucky Hiro Nakamura gets some pretty dark revenge on immortal KnightTemplar Adam Monroe for [[YouKilledMyFather killing his father Kaito]]. [[spoiler: He [[BuriedAlive buries him alive]] in the same graveyard where his father was buried, with nothing to keep Adam company but his own screams]]. Do not piss off Hiro.
191** His FutureBadass self in "Five Years Gone" should have been a warning...
192*** Adam himself, arguably. He comes across as a friendly guy, decent, and caring (at least in modern times; in the past, he's been a mercenary on at least four separate occasions) -- he just happens to want to wipe out billions of people and choose who survives to live in his new perfect world, is all. Hiro's too much of a [[TheCape Cape]] to do that for pure revenge -- this is a guy the world does ''not'' need to have turning up again.
193*** Future!Sylar is shown as [[BumblingDad a doting father,]] who loves to bake waffles for his son. Then [[TheCorpsIsMother Company]] appears. [[InnocentBystander Syndicate shot his son.]] [[PapaWolf Sylar]] [[UnstoppableRage goes nuclear.]] [[EarthShatteringKaboom LITERALLY.]]
194*** The really cool thing about this scene is how he's taking blows from a guy with super strength to protect his son. When that guy crushes his son with a table, Sylar steals his ability, beats the living crap out of him, then FRICKIN EXPLODES. Don't kill his son.
195*** Only character to come out of Volume 3 BETTER. Who'da thunk it?
196** From the graphic novels, Linda Tarvara. A friendly, personable young girl with a caring demeanour who is often polite to people. She's dedicated and takes pride in her work. She also murders people by RIPPING OUT THEIR SOULS so she can FEED on their abilities. Her first human victim? A sweet, lovely old woman who she tricks, traps, and murders, all while acting kind and considerate. This girl makes Sylar look like a candidate for sainthood (Season 1 Sylar mind you, the emotionless murder machine, not the "Morally Grey" character of Season 3).
197** Matt Parkman. Good-natured, loving surrogate father to Molly and a man who desperately wants to be the best husband he can. But: Mess with his family or friends and expect trouble, as the fascist soldiers under the command of Emile Danko learned when Matt forced them to slaughter each other.
198*** Or with Sylar. [[spoiler: Locking him in a prison within his own mind, an empty world where ''years'' pass for every hour of real time, and then sealing his body behind a brick wall]] should do the trick. [[spoiler: For two episodes, anyway]]. Mind you, Sylar borrowed Claire's HealingFactor and used his newfound shape-shifting ability to ''move'' the part of the brain that can be attacked to disable it, so it's not like [[WhyDontYaJustShootHim a bullet]] will bother him. Some of these villains are so powerful that you ''have'' to get creative to be ''sure'' they won't be back to relieve you of your gray matter someday. Notice that ''even these things almost never work!''
199** Claire Bennet has shades of this. While she [[IJustWantToBeNormal just wants a normal life]], she's also quick to make use of her [[HealingFactor powers]] to protect people she loves... or destroy those who have hurt her. Take Brody Mitchum, who [[AttemptedRape tried to rape her]], and turned out to have raped someone else. She drove his car into a brick wall. While he was in it.
200*** Let's not forget playing a major part in the bringing down of a plane, rescuing Eric Doyle from pursuing gun-toting agents, and bringing serious harm to Sylar on several occasions (including putting a pencil to the nastiest use since Creator/RachelMcAdams in ''Film/RedEye'').
201*** She is immortal, feels no pain, and is practically fearless. Not someone you want as an enemy.
202** Mohinder, anyone? Sure, he's become a bit of a ButtMonkey and is frequently handed the IdiotBall. But let's not forget how he smiled and laughed and acted completely sweet and naive around Sylar... right before serving Sylar sedative-laced tea, strapping him to a chair, torturing him with ''[[CoolAndUnusualPunishment a tuning fork]]'', and then ramming a huge needle into Sylar's ''spine''. And laughing about it. Damn, Mohinder.
203*** Not to mention [[PsychoSerum what]] [[NotHimself he]] [[AxeCrazy did]] [[AllWebbedUp in]] [[MadScientist Volume]] [[TheDragon 3]]. Nathan comments, with delicious DramaticIrony, "Dr. Suresh? He's harmless." Oops. . .
204* ''Series/HighwayToHeaven'': A third season episode, titled "That's Our Dad", features Creator/NedBeatty as Bill Cassidy, who plays a model father on-screen but is an insufferable jerk off-camera. Two kids who live in a foster home are ardent fans of "That's Our Dad" and want to be adopted (for real) by the actor, unaware that Cassidy's "adoption of two kids" at the end of each episode is a promotional trick. After the two foster kids learn the cruel truth about Cassidy, Jonathan helps set Cassidy straight and tells him he needs to live to his expectations.
205** Jonathan in general is very much this trope. He's an angel, with all of the AllLovingHero nature that implies. But if you mess with [[HeterosexualLifePartners Mark,]] [[NotHyperbole May God have mercy on your soul]].
206* ''Series/HillStreetBlues'': Detective Henry Goldblume of Hill Street Precinct. NiceGuy and ByTheBookCop almost to a fault, pretty much the most idealistic and principled officer in the department to the point where he comes off as [[WideEyedIdealist downright naive]] and never loses his idealism even after seven seasons of CharacterDevelopment... Which make the handful of times he gets angry enough to [[PerpSweating get heavy-handed with a suspect in Interrogation]] or [[CowboyCop threaten to bend the law to make sure someone doesn't get away with something]] [[OOCIsSeriousBusiness all the more genuinely startling]] and very effective for it.
207* ''Series/HoratioHornblower'': Lieutenant Archie Kennedy has a sunny disposition and is never seen being too strict on his men when he's in command. However, he really does not like seeing Midshipman Wellard abused in Series Two; this probably has a great deal to do with the suffering he endured as a midshipman. When Randall, one of the lower-deck sailors and below Wellard in rank, calls the latter "little boy" and mocks him, Archie gives him a pretty epic shout-down. And when Captain Sawyer has Wellard beaten multiple times for no good reason, the rest of the lieutenants are angry at the injustice but Archie is positively seething.
208* In ''Series/{{House}}'', Dr. James Wilson seems deeply kind, caring, and eternally compassionate to his patients, and nearly as much so to his friends. And he is, until he gets pushed far enough to reveal that deep down, he can be just as much of a cold, snarky manipulative bastard as House -- maybe even more so. He just chooses not to be because it seems healthier.
209* In ''Series/HouseOfAnubis'', Fabian is often believed to be one of the nicest people in the house, as well as an EndearinglyDorky ExtremeDoormat. But if you threaten or insult Nina in his presence, he ''will'' lash out at you for it, with varying degrees of anger depending on what (he thinks) you did. One of the most famous examples is when he got ''violent'' with Eddie, after having been led to believe Eddie did something to Nina. Alfie, despite being strong, could barely hold him back, and he only stopped when Eddie promised to tell him the truth.
210** Mara is a lot like Fabian, but maybe even more dorky and adorable at times. However, she can become an outright ''bully'' if she feels jealous or betrayed by a loved one.
211* Marshall of ''Series/HowIMetYourMother'' is a very sweet lovable lug of a guy. But when Ted gets punched out in a fight, he punches the other guy out, much to the surprise of everyone. Turns out he routinely used to have brutal no-holds-barred beatdowns with his brothers for the hell of it.
212** Marshall set up a website with a countdown to one of his slaps months in advance, just to make Barney suffer as much as possible. Eventually, Lily got sick of the whole thing ruining her Thanksgiving and forbade slapping, but then Barney pissed her off and she gave the go-ahead. After slapping Barney, Marshall then sings a song he composed about it, just to rub it in.
213** In gratitude for finding the Thanksgiving turkey he'd lost, Marshall gave Ted and Robin the fourth slap. He tied Barney to a chair (the "slapping throne"), prolonged it as long as he could, allowed every other person the opportunity to slap him instead, declared that there would be no slap, untied him, then slapped him so hard he fell over.
214* ''Series/ICarly'': Good-natured Gibby can endure being bullied, just don't let him discover you're hitting on his girlfriend.
215** Carly Shay is very sassy at times, but she does have a long temper. To short it out is not a good idea. It was the focus of "iThink They Kissed". Carly's always open to her best friends about her secrets, but when she learns of her [[FirstKiss best friends' secret]] that was kept from her, she gets "whipped up" about it. In such a state, NEVER tell her to calm down.
216** The oh, so nice Freddie Benson also seems to have his sadistic sides, especially towards Gibby ("iWon't Cancel the Show") and Nevel.
217--->'''Freddie''': Because in 20 years, I guarantee you, I will be Carly's second husband.\
218'''Carly''': What happened to my first husband?\
219'''Freddie''': Nothing ''you'' can prove.
220* In ''Series/{{Ideal}}'' Steve is part of a small gang and is the buttmonkey. At one point he snaps cuts off Cartoon Head's ear (he's got a mouse face glued on his head so think more plastic, less blood) and knocks out Psycho Paul and becomes the leader of the gang for a few episodes. It turns out he just can't keep up the tough-guy facade and tries to get everybody back to normal by apologising and asking for Paul to become leader again. Paul accepts but not before removing one of his eyes. Did I mention the show is a comedy?
221* Perhaps best summarized in the pilot episode (and opening) of ''Series/TheIncredibleHulk1977''. "Mr. [=McGee=], don't make me angry. You wouldn't like me when I'm angry." Remember that in this version, the Hulk essentially is Banner, but with tremendous strength, and a child's mentality.
222* Stan from ''Series/InPlainSight'':
223-->'''Malone''': So, Stan [=McQueen=]. "Little Jack", I used to call him.\
224'''Marshall''': Why is that?\
225'''Malone''': Because he's like a Jack Russell Terrier. Pound for pound, probably the toughest man I know.\
226'''Mary and Marshall''': Stan?\
227'''Malone''': Well, you know, he plays that shy, quiet thing pretty well, but you don't want to be the guy he's looking at when the switch flips.\
228'''Mary''': I didn't even know he had a switch.
229* On ''Series/{{JAG}}'', Bud and Harriet are the sweetest couple and good parents, but both go on the warpath if someone screws over their spouse.
230* ''Franchise/KamenRider'':
231** ''Series/KamenRiderKuuga'''s title character, Yuusuke Godai, is normally a kind-hearted guy who wants nothing more than to protect people's smiles, and is [[FriendToAllChildren especially good with kids]]. But as one sadistic Grongi learned the hard way in episode 35, it is ''not'' a good idea to push him too far. Said Grongi ended up on the receiving end of one of the most frightening {{Unstoppable Rage}}s of the entire franchise, a savage NoHoldsBarredBeatdown that culminated with Godai finishing him off with a rage-fueled Rising Calamity Titan attack.
232** Then there's the Linto tribe, pacifistic and nature-loving ancestors of humanity. The Grongi tribe has been systematically murdering the Linto as a macabre game. One day the Linto decide enough is enough, create the [[TransformationTrinket Arcle]], and select a champion to wield it against the Grongi. That champion is Riku, who becomes the first Kuuga. Alone, Riku proceeds to comprehensively hand the Grongi their asses, defeat their leader (who is ''the'' strongest Grongi), and seal them ([[HeroicSacrifice and himself]]) away for the next two thousand years, all without access to any of the [[SuperMode Rising forms]] Godai has.
233** Yuka Osada from ''Series/KamenRider555'' also fits into this trope at times. Normally she's quiet and polite but hurt her friends or be a bully and it won't be pretty.
234** ''Series/KamenRiderZiO'''s title character, Sougo Tokiwa, is a flaky and strange high school student who wants to be a king. Despite his odd characteristics, he is genuinely a nice guy for the most part. When he discovers that his future self 50 years into the future is an EvilOverlord who rules the world with an iron fist, he does everything in his power to avert that future. Too bad the BigBad of the series doesn't allow that and wants him to go down that path so that he can steal all his potential power to become the ruler of all of time and space. To this end, he masterminds one horrible event after another to push Sougo past his DespairEventHorizon. In the final episode, he succeeds in doing so and awakens all of his power. He quickly regrets that decision when he realizes that Sougo's power far exceeds his imagination and proves [[TooSpicyForYogSothoth too powerful to be stolen]], in desperation he tries to run. He doesn't get very far before Sougo sends him to the grave.
235** In ''Series/KamenRiderGeats'', several of the main characters fall into this trope.
236*** While Ace isn't exactly the ''nicest'' guy, he still has moments where he shows his soft side like paying for the surgery for another player's son or giving others a fighting chance at the end of their rope. Mess with his friends however, and he will not hesitate to [[CurbStompBattle feed you or your lackeys the floor,]] as Beroba witnessed during the bullfighting game of the JGP.
237*** Keiwa Sakurai is one of if not the most good-natured and caring Rider of the series. After [[spoiler:the death of his sister however, he loses himself to despair and proceeds to brutally manhandle those responsible for her death before using the Power of Creation to turn the world into his own warped dystopia.]]
238*** [[spoiler:Neon Kurama may seem like a cutesy Youtube influencer, but mess with her family after they've reconciled and she'll take you down ''hard.'']]
239* EADA Ben Stone of ''Series/LawAndOrder'' is a real NiceGuy, especially when compared to his successors, JerkAss Jack [=McCoy=] and borderline SmugSnake Mike Cutter. But if you managed to push his buttons, watch out. He will destroy you, all while remaining [[TranquilFury perfectly calm]].
240* ''Series/LawAndOrderUK'': And in similar fashion, across the pond, we have DS Matt Devlin, who's also basically a very NiceGuy, and even manages to remain so while chasing and interrogating suspects. But push one of ''his'' buttons (child abuse, Alesha Phillips, Ronnie Brooks), and it'll take every ounce of his self-control to not wring your neck.
241-->''[as he and Ronnie arrest Dr. Merrick, Alesha's rapist]''
242-->'''Merrick:''' ''(whines as Matt cuffs him)'' "You're hurting me!"
243-->'''Matt:''' "Yeah, I know."
244-->''[the fact that he '''smiles''' as he says/does this just drives the point home]''
245* ''{{Series/Legion|2017}}'': Charles Xavier is sweet and gullible, so he's easily LuredIntoATrap set up by Amahl Farouk. However, the latter makes the mistake of underestimating the former's telepathic skills when they get embroiled in a BattleInTheCenterOfTheMind because Charles vanquishes Farouk by ripping out his foe's consciousness from his body.
246* ''Series/{{Letterkenny}}'': Squirrely Dan is the most open-minded and affable of the four main characters, yet he is also the quickest to fly into rages. As a member of Wayne's crew, he's a seasoned street fighter as well as TheBigGuy.
247* The main cast of ''Series/{{Leverage}}'' is more or less this ''all the time'': if you're their client, they'll move heaven and earth to help you; if you're their mark ... And heaven help you [[FateWorseThanDeath if you make them mad]].
248* ''Series/{{Lost}}'':
249** Juliet. As seen in her flashbacks, she used to be an incredibly mousy and docile person, frequently letting people (especially her ex-husband) walk all over her but all of that changed [[BreakTheCutie when she got to the island and met Ben Linus, who extended her six-month stay there to eternity]]. Since then and especially after discovering [[spoiler:Ben's many other lies to her, including his involvement in her lover's death]] she [[TookALevelInBadass took several levels in badass]]. The biggest evidence of the damage done to her comes in Season 5, [[spoiler: when Sawyer's throwaway look at Kate turns out to be the last straw and Juliet decides that the only response she can muster is to detonate a hydrogen bomb]].
250** Ben isn't ''nice'' per-see, but he certainly is [[AffablyEvil polite and well spoken]], if a little power-hungry. However, mess with the people he cares about or ''dare'' try to harm the island or his people and he will get... [[UnstoppableRage ANGRY]] ([[PsychoForHire Keamy]] found this out when he killed his daughter)
251** Kate: Her sweet girl-next-door demeanor is genuine, but so are her more violent and manipulative aspects.
252** Charlie. He and Hurley tie for Friendliest Survivor, but if you do ''anything'' to hurt Claire, Charlie will cut you down in cold blood.
253** Hurley himself. Generally treated as [[BigFun a big cuddly teddy bear]] at best or TheLoad at worst by the other castaways, he has shown himself capable of delivering a NoHoldsBarredBeatdown to Sawyer (while screaming every unkind nickname Sawyer ever threw at him) and mowing down a bunch of Dharma thugs with his Winnebago van.
254** Sun is the one of gentlest and least violent of the flight 815 survivors, if not one of the gentlest characters in the series. Just don't hurt her husband, or she ''will'' ruin your life, [[spoiler:as her father finds out.]]
255* ''Series/MadMen'': Lane Pryce is quite the calm fellow but if you press his buttons too hard like Pete did in season 5, he will challenge you to a fistfight and he'll beat you. Pete found that out the hard way.
256* ''Series/{{MASH}}'':
257** In the episode "Period of Adjustment", nice guy B.J. has enough of the war, gets nasty-drunk, throws darts at Radar in effigy, smashes the still with a chair, and punches his best friend in the mouth.
258** Father Francis Mulcahy. As expected of a sincere man of God, he strives to be compassionate, patient, and forgiving. Sometimes though, the right thing has to be done whether you like it or not, and if he can't convince you with wise words, a fist in your mouth makes an acceptable substitute. He feels pretty bad about it afterwards, but regardless. Remember that before he was a priest, he was a boxer.
259** Hawkeye is normally a nice guy with a penchant for pulling pranks. However, if he finds out you are causing harm to children, he doesn't care if you are in the army as well — you are going to get it.
260** There's Radar, a shy but kind guy with a love for animals. Hurt said animals, though, and there's not much that can save you. Also, don't shoot the bugle out of his hands with a cannon, even if it was by accident. He'll still need someone to hold him back.
261* ''Series/{{Merlin|2008}}'':
262** Merlin. Adorable, loyal, but [[OhCrap God help you if you ever try to kill anyone he cares about because that is the last thing you will ever do.]] His anger is sudden and his powers are fierce and he ''will'' blast you off the face of the Earth. Keep in mind that this is ''the most powerful sorcerer the world has ever known.'' If he wants to tear mountains apart, ''he can do it''. Please don't make him. He also has the highest body count in the series, can pretty much stop time, and can kill you just by looking at you. And do it with absolutely no emotion. In-Universe, he's a LethalJokeCharacter.
263--->'''Merlin:''' You should not have killed my friend. ''[[[BadassAdorable pulls lightning from the sky and blasts]] [[spoiler: [[TooDumbToLive Nimueh]]]] to ashes]''
264** Guinevere. Nice gal, but she can tick off at times, like say, with Arthur, and do ''not'' betray her knights, [[MamaBear or she'll execute you]].
265* ''Series/TheMiddleman''. An old-fashioned, milk-drinking, seldom-swearing, well-dressed, earnest, polite, and naive gentleman who [[spoiler: tortured a mob leader for info in front of his own bar, while drinking a tall, frosty glass of milk.]]
266* Frank Black from ''Series/Millennium1996'' is mild-mannered, law-abiding, honorable, and dearly loves his family. It's also heavily implied through the first season that the reason he is so gifted in understanding the minds of serial killers is that he has the traits of a killer himself ("I become the capability, I become the horror, what we know we can become in our heart of darkness") [[spoiler: culminating in him brutally butchering the man who kidnapped his wife.]]
267* ''Series/ModernFamily'': Phil often tries to be the peacemaker, even when Haley is arrested for underage drinking, resisting arrest, and assaulting a police officer. But when she calls herself the victim, Phil's long-buried "stern father" side comes out with a vengeance, and the epic chewing-out Haley receives makes her realize how irresponsible she's been. Or the time Alex and Haley lied to him about finishing their chores so they could go out, prompting him to jump on the hood of a moving car to stop them. Or the time the kids wouldn't stop fighting on their RV trip. Phil is normally a pretty laid-back guy, so when he ''does'' lose it everybody is immediately cowed into frightened obedience.
268* All of ''Series/TheMusketeers'' are arguably this as though they range in [[TheStoic levels of]] [[NiceGuy friendliness]] [[OfficerAndAGentleman they are all polite and honourable men]] who care about others. Mess with France, an innocent or one of their loved ones and you’ll quickly find out why their [[BadassCrew regiment is so elite]] [[MasterSwordsman and why they’re feared and]] [[LivingLegend respected as the best of the best.]]
269** Special mention must go to Aramis who is probably the friendliest, most open-minded, and forgiving. He even prays for his enemies. Threaten someone he cares about (especially if that someone is [[HeterosexualLifePartners Porthos]], [[RescueRomance Queen Anne,]] [[PapaWolf the Dauphin or another child)]] and you’ll be reminded, painfully if not fatally, that he’s still a [[DanceBattler skilled, veteran soldier]],[[DualWielding a capable swordsman]] and [[FriendlySniper widely considered the best shot in France]].
270** Queen Anne too. Her [[TheHighQueen compassion]], [[HairOfGoldHeartOfGold gentleness]] and [[WideEyedIdealist idealism]] are noted by many characters and she's the only member of the cast who has zero combat training. She's also the Queen of France and the King of Spain's sister and has the [[UniversallyBelovedLeader adoration of the aforementioned elite regiment of soldiers]] who have [[UndyingLoyalty committed treason for her]]. Insult her Spanish heritage, [[SilkHidingSteel she'll snark right back.]] Attempt to have her secretly assassinated, she'll get evidence and hold it against you. Try to [[AttemptedRape force yourself on her]], [[EyeScream lose an eye]]. Have her falsely arrested, [[DefiantCaptive she'll do everything she can to make it difficult for you]]. [[MamaBear Threaten her son...]]
271* All of the main cast of ''Series/{{NCIS}}'', being a team of {{Bunny Ears Lawyer}}s, are capable of [[OhCrap surprising any antagonist with their competence]] (especially those who surprise them first), but especially notable is [[BadassAdorable Abby]], the PerkyGoth [[TheLabRat Lab Rat]] who, as a civilian scientist and all-around GenkiGirl, ''seems'' like an easy target... and neatly puts her steel-toed boots to almost every villain who's made that unfortunate assumption.
272-->"Always remember; I am one of the few people on Earth who can kill you and leave no forensic evidence."
273** In ''Series/NCISNewOrleans'', Dwayne Pride is damn near the friendliest guy you'll ever meet; he's a proud family man wholly dedicated to his daughter, his team, and his city, [[HonorBeforeReason and is prone to acts of charity most others would find nonsensical]]. However, his hyper-competence, [[ChronicHeroSyndrome his compulsive need to]] [[ItsAllMyFault solve everyone's problems as if they're his own]], and his unresolved anger/daddy issues make him a living nightmare for criminals who sufficiently piss him off.
274* British detective series ''Series/NewTricks'':
275** Jack Halford is a quiet, softly-spoken, and wise old cop who acts as a mentor to the rest of the team... who possesses, if sufficiently roused, a fierce and at times even violent temper. Do not taunt him about his dead wife, either.
276** Superintendent Sandra Pullman is very nice, but that didn't stop her breaking the nose of a member of a biker gang who was holding a gun to her head, with her elbow, after talking him down.
277** It should be remembered that all three of the older detectives were respected and successful detectives during the time period of shows like ''Series/{{Life On Mars|2006}}'' and ''Series/AshesToAshes2008''. That's right, they are basically Gene Hunt with an extra thirty years of experience to mellow them out. But the Gene Hunt is still there somewhere. Particularly chilling is when Jack shows just how much he can intimidate a younger criminal, pointing out that while he might not be able to directly hurt the criminal, he could [[spoiler:Let the criminal's name slip on the witness stand as helpful to the investigation. Which would lead to the criminal being killed or attacked in prison as a rat. What's even worse is that he says that he's done it before, and there is nothing to suggest that that's a bluff.]]
278* ''Series/OddSquad'':
279** Olive may be a snarky, sassy JerkWithAHeartOfGold who is prone to brief bits of anger from time to time, but episodes such as "Now You Don't See Me" and "My Better Half" show that it's not a good idea to make her completely enraged. One EstablishingCharacterMoment shown in the very first episode, "Zero Effect", has her going with Otto to confront Glenn at his new cupcake shop, tearing the sign with all the zeroes down, then stomping on it to release the zeroes in a fit of rage. Otto tries to stop her, but it only works for a second before she screams and goes from stomping on the sign to doing a ''full-body slam'' onto it. Perhaps what makes her even more terrifying when she's angry is the fact that she's one of the most athletic and one of the strongest members of the cast, second only to Ms. O.
280** Otto also plays this trope straight. While he's mostly known for being a NiceGuy and a bit of a {{Cloudcuckoolander}}, he's not without his angry moments, and when he does get angry, it's not a pretty side of him to see. "The Curious Case of Pirate-itis" is a great example of this, as when he and Oscar go to visit [[ThePrankster Odelia,]] he has extremely little patience for the practical jokes she plays on him.
281** By far the biggest example of this trope is Ms. O, who is far and away the strongest of the entire main cast and rules over Precinct 13579 with an iron fist. Even when she mellows out considerably from Season 2 onwards, it's still made abundantly clear that making her angry is ''not'' a good idea.
282** Olympia is an overly sweet GenkiGirl who is a severe {{Workaholic}} and is completely loyal to Odd Squad through thick and thin. However, quite a few episodes have shown that even she has her limits. In "The Perfect Score", she spends the entire day hunting down a villain who gave her a 1 out of 10 on her villain report card with no slowing down, and in "Drop Gadget Repeat", she manages to grow enraged enough to tell Orchid, who is infamously known for being TheDreaded BrattyHalfPint of the precinct, off.
283** Oona may be a GadgeteerGenius and a GeniusDitz in a similar vein as Oscar, but one of her other defining traits is being CuteAndPsycho, and it's definitely not a good idea to push her past her breaking point. "The Cherry-on-Top-inator" in particular has her being stretched to her limits by her co-workers when they try to tell her how the eponymous gadget helped them, but how it helped them are ways that don't involve the gadget's intended use. And that's not even mentioning her psychotic screams whenever she goes to smash the gadget with her large mallet.
284** Opal is the de facto leader of the Odd Squad Mobile Unit, who is always up for adventure and is generally a kindhearted agent. But she also has moments of being extremely quick to anger, such as in "Running on Empty" when she snaps at Oswald after he suggests the team call the Big O about their low-fuel situation, and in "Raising the Bar" when she shoots a DeathGlare at Omar after he says that the "most odd cases solved" graph listed in the Odd Squad Magazine is incorrect.
285** Orla is another example of a strong, athletic character who falls under this trope. Like Olive and Ms. O, she is one of the strongest agents of the main cast, who was tasked with being the guardian of an ancient Odd Squad artifact and is completely unfamiliar with the modern age. While she mellows out over the course of Season 3, being less about solving oddness with violence and overkill (as was common practice back in her time) and more about solving oddness practically, she has shown that she isn't afraid to rush into battle LeeroyJenkins style, and hurting her friends is a ''very'' bad idea. One example of this is in "Portalandia", where she has to bite back her tongue when interacting with a Portal Master store employee when he tries to convince her to sign up for the Portal Club, settling for TranquilFury.
286* Erin on ''Series/TheOfficeUS'' is the cute [[ThePollyanna Pollyanna]] and borderline CloudCuckoolander. Upon realizing Andy was engaged to Angela she goes ''nuts'' and ends up chucking a cake at him!
287* ''Series/OnceUponATime'': Snow White is pretty nice, and a genuinely sweet person. But she's been shown to be [[GirlyBruiser a hell of a fighter]], and ''gods help you'' if you [[MamaBear endanger Emma]].
288** After being screwed over by Regina and her mother Cora one time too many, including the murder of both her parents and the maid who was a mother figure to her after the fact, Snow finally retaliates and [[spoiler: curses Cora's heart and tricks Regina into putting it back into her mother's body, killing her]].
289** Her husband is, literally, PrinceCharming. He's also a PapaWolf, and one of the very few things that can get him angry is some idiot pressing his RelativeButton, assuming that "nice" equals "weak". [[GoodIsNotDumb It doesn't]]. It really, ''really'' doesn't.
290* ''Series/{{Oobi}}'': In a particularly memetic scene, Oobi goes berserk when Uma breaks his toy car after promising to be careful with it.
291* ''Series/{{Oz}}'':
292** Hill is the OnlySaneMan of the prisoners, and one of the few to be genuinely atoning for his crimes. Threaten anyone close to him, however, and you'll be dead very fast. Just ask [[spoiler:Supreme Allah]].
293** Beecher is shy and compassionate, and one of the few inmates with anything resembling a moral code. He's also simultaneously one of the most vicious inmates, and a murderer several times over.
294** Rebadow is a friendly, sweet old man, who just so happens to be in prison for [[DisproportionateRetribution murdering a guy for laughing at him.]]
295* Balki from ''Series/PerfectStrangers'' is a very sweet, friendly guy, but threaten his cousin Larry and he will have you on your knees.
296* ''Franchise/PowerRangers'':
297** ''Series/MightyMorphinPowerRangers''
298*** Kimberly. A tiny wisp of a creature who doesn't appear to weigh 100 pounds, she acts like an '80s ValleyGirl more times than not, but when threatened she becomes one of the toughest rangers ever. Made even more obvious with her weapon, The Power Bow. Her arrows have been shown to be able to turn corners and navigate through trees, meaning she has what amounts to a portable rocket launcher at her disposal. Anyone watching the first season quickly rediscovers a season-long running theme. Whenever Kimberly shows up looking angry, the monster ''dies''. In one example, Kimberly arrives to find the other five Rangers incapacitated. So she single-handedly annihilates an entire army of putties ''by shooting them one-by-one with her bow'', then takes out the monster seconds later.
299*** Billy Cranston. Most of the time, he's an adorable nerd. In one episode after the MonsterOfTheWeek attacks his new alien friend, however, he ''snaps and shoots the MOTW without warning''.
300--->'''Billy:''' DON'T EVER HURT ONE OF MY FRIENDS AGAIN! ''[shoots MOTW into a wall]''
301** ''Series/PowerRangersMysticForce''
302*** Itassis. Considering how calm and mild-mannered Itassis is for most of series you would be forgiven for thinking that Itassis doesn't have a temper but after Necrolai brings Itassis back from the dead, Itassis destroys Sculpin single-handed.
303* ''Series/PrincessAgents'': Most of the time Yan Xun is a good-natured guy who's rarely seen without a smile. But if you hurt someone he cares about -- or even worse, murder his family -- then he ''will'' kill you.
304* ''Series/RoyalPains'': Divya: "Evan, if you breathe a word of this to anyone I will find a medically plausible way to kill you, and get away with it."
305%%* ''Series/{{Scandal}}'': Olivia.
306* ''Series/ScarecrowAndMrsKing'': Don't mess with Season 4's quirky antiquarian T.P. Aquinas, who has spent years plotting his revenge against the drug lord who murdered his wife and young son. He succeeds when he detonates the car that the drug lord is riding in.
307%% ** Amanda King
308* ''Series/SchittsCreek'':
309** Johnny Rose gets irritated with his family, but he rarely if ever loses his temper with them. That changes in the ChristmasEpisode, when his family thwarts his plans for a Christmas party with their typical selfishness and cluelessness. Naturally, after Johnny blows up, the Roses get it together and throw the party.
310** Joceyln Schitt is generally sweet and kind, but when her friends continue to ignore her sleep deprivation and stress, she flies into a rage and says they are acting like B-words.
311* Blair Sandburg in ''Series/TheSentinel''. Anthropology grad student, raised by a mother who could be described as "the last flower child not gone to seed" — but threaten (or even worse, ''hurt'') Jim and you'll wish you had left matters well enough alone.
312* ''Series/{{Sherlock}}'':
313** Doctor John Watson is an unassuming, gentle soul who lets Sherlock order him around on their adventures. It's so easy to forget that [[RetiredBadass he has recently seen active service in Afghanistan,]] and shot a serial killer dead, between two buildings, through two windows, with a handgun, in the ''first episode'' of the show. And shows absolutely no remorse about it.
314** Two major bad-guy deaths over the first three Sherlock episodes, BOTH of them killed by John Watson, the second in "The Blind Banker", [[spoiler: where he successfully offs a Chinese gangster trying to simultaneously kill both Sarah and Sherlock]] by one movement of his leg. Which happens to be tied to a chair at the time.
315** It's a pretty bad idea to insult Sherlock in front of John. Just ask the Chief Superintendent of Scotland Yard. You will wind up with a bloody nose, though at least you'll get it fixed. That is, ''if'' he chooses to. But piss him off ''so much'' by messing with his friend, and he'll calmly, coldly KILL YOU.
316--->'''John:''' I was a soldier! I killed people!\
317'''Sherlock:''' You were a ''[[TheMedic doctor]]''!\
318'''John:''' I had bad days!!
319** Mary. Thought to be a normal, nice, silly, sweet girl but she was an assassin. She also DID shoot Sherlock. Not the type of lady you'd want to mess with. She might get along with Sherlock, but since this chick was an assassin, it's not a smart move to mess with her.
320** Molly is generally TheQuietOne, but she called Sherlock out on his rude behavior and calls him out on his stupidity for his doing drugs. Again. which leads to (you guessed it) ''everyone'' being annoyed. Including John!
321* Jared on ''Series/SiliconValley'' is the meekest pushover on the show, but he's also not someone to mess with when he's strained. He will absolutely destroy anyone who he thinks is a threat to Richard, and Richard himself isn't immune to his fury.
322* Similarly, Clark Kent from ''Series/{{Smallville}}'' (at least before a nonsensical transformation at the end of Season 8) is a shy, humble, unassuming young man, generally avoiding the limelight and talking his way out of battles; even when he does fight, he'd rather use defensive maneuvers to defeat his foes. But when ''anything'' bad happens to a member of his family, from his parents to his friends to Lana, all bets are off.
323* ''Series/SpaceCases'': On the ''very second episode'', the normally [[TheWoobie shy and self-effacing]] Radu [[spoiler:gets infected with a virus, planted onto a teddy bear by an alien race as a form of biological warfare]], and [[UnstoppableRage goes berserk]]. Before his illness-induced rampage is halted, the 'recreation room' is trashed, the ship's dotty android is in pieces, and Harlan almost gets ThrownOutTheAirlock.
324* ''Series/SpartacusBloodAndSand'' has the generally quiet and meek Aurelia, wife of Varro. She seems to be the only delicate flower in a ludus filled with gladiators, guards, and soldiers. Then we learn that she castrated her rapist. In the final episode, she brutally [[spoiler:stabs to death the teenager who callously ordered Varro's death]]. Even Sparty and Doctore (you know -- the deadliest gladiator in the republic, and the man who trained him) are kind of squicked by her rage when they arrive on scene.
325* ''Franchise/{{Stargate Verse}}'':
326** While Rodney [=McKay=] of ''Series/StargateAtlantis'' isn't really nice ''per se'', he's the most nonviolent character on any offworld team, and his wide blue {{woobie}} eyes make him victim fodder, not to mention the many times he's kidnapped. But he will often unleash a barrage of infinite {{The Reason You Suck speech}}es at the bad guy, or even his own team members when particularly stressed. That said, please don't give him Wraith enzyme. Ever.
327** And while [[Series/StargateSG1 Dr. Daniel Jackson]] really wants to get to know you and your culture, is a very sweet and gentle guy, and would [[ReluctantWarrior prefer not to fight]], if he has to, he will mess you up at least as badly as his career-military teammates because of his fierce determination to do the right thing. The man will NOT give up, even if he has to sacrifice himself to do it. And then he will somehow turn up alive again because he's just that kind of person. He also calmly threatened to kill Apophis if he didn't tell him where Sha're was. The whole of the first five seasons is basically his equivalent of a RoaringRampageOfRevenge. He's so nice, he barely even raised his voice, he just embarked on the genocide of the species that took his wife from him. We get a first glimpse of this in a first season episode, where he and Carter are standing over an incubator of Goa'uld children. He comments that the Goa'uld will grow up and enslave humans, and Carter responds with "Yes, but if we kill them now then we're no better than they are." Jackson, after pausing for a second, seems to accept it, starts to walk away... and then he spins and fires a submachine gun burst into the incubator, killing the Goa'ulds. That's for my wife, bitch.
328** Samantha Carter is a good-natured, genial nerdy type, but she's also career military and can kick your ass in a second flat. Sam's evil galaxy conquering replicator double shows that we should consider ourselves fortunate to have Sam on our side. After all, [[RememberWhenYouBlewUpASun she blows up suns]].
329** ''Series/StargateAtlantis'': Teyla tends to be more calm than Sheppard and Ronon, and much more likely to grant mercy to bad guys. That said, don't threaten any of her loved ones: her fellow Athosians, her team members, and, most importantly, her son, Torren. She did [[spoiler: kick Michael off the central tower of Atlantis, after all.]]
330* In ''Series/{{Stargirl|2020}}'', [[Creator/LukeWilson Pat Dugan]] seems to be a friendly neighborhood mechanic. Sure, he used to be a superhero's sidekick back in the day (and served in the army before that), but he was never truly a part of the team, just the team's mechanic. But if you're a bully who likes to pick on those weaker than you... well, it won't be pretty, as Rick's uncle learns when he refuses to drop the charges against his nephew out of spite. Oh, and you definitely don't threaten or insult his family, ever. When his stepdaughter's biological dad showed how much of a deadbeat he really was, Pat decked him on the spot and told him to never show his face in town again.
331* ''Franchise/StarTrek'':
332** Spock in ''Series/StarTrekTheOriginalSeries''. Generally a pacifist, but the very few times he loses his temper make it blatantly obvious ''[[OhCrap why]]'' Vulcans keep such strong control over their emotions. And that's not even mentioning the times when something threatens Kirk and the pacifist Vulcan [[BewaretheQuietOnes becomes rapidly]] ''un'' pacifist.
333*** A key example would be ''Devil in the Dark'' where Spock went out of his way to try to protect the creature that was sabotaging the mine station and killing the miners, even attempting to defy Kirk and have it brought in unharmed. Once Kirk was facing the creature, though, even though it's not even moving, Spock immediately starts baying for its blood and has to be ordered not to attack it. [[spoiler: Thankfully it turns out the [[MonsterIsAMommy creature was just trying to protect her eggs]] and it all works out for the best.]]
334** The Vulcans in general have this going on. They are polite, intelligent, and calm (if not a bit cold and stiff, and often passive-aggressively [[FantasticRacism racist]]) most of the time. They've devoted themselves to logic and pacifism because they ''had to'': they have a capacity for violence and cruelty that gives even Klingons pause, and the only way they survived as a species was to develop a culture centered around suppressing that side of themselves. Whenever Vulcan rage is unleashed, it's very bad news for anyone in their way.
335*** In ''Series/StarTrekDiscovery'', it's revealed that once they figured out how aggressive Klingons were the Vulcans took to always firing first since logically that was the best way to show Klingons they meant business and deserved respect.
336** Jean-Luc Picard is often underestimated when compared to other ''Franchise/StarTrek'' Captains. Sisko is a rough and tumble young Commander who evolves into a battle-hardened warrior who gets his hands dirty on the ground just as well as on his custom-built battleship, Janeway is always willing to step into the line of fire for her crew and Kirk is a heroic alpha male who relishes personal combat. Then you have this skinny, bald, tea-drinking Frenchman who can recite Shakespeare and is one of the Federations utmost diplomats & historians. You can forget that he has managed to:
337*** Survive interacting with the highest echelons of the Klingon's deadly palace intrigue and killed Klingons bare-handed.
338*** Survive Borg assimilation.
339*** Survive Cardassian's infamous torture
340*** Survive barfights with large species and taking a large knife to the heart.
341*** Told Romulans where to stick it and sent them packing.
342*** Single-handedly thwarted having his ship hijacked multiple times.
343*** Told Starfleet officers several ranks above him to shove it.
344*** Caused omnipotent aliens to bow to him.
345*** Outfoxed at least one member of every known species in the Alpha Quadrant at least once.
346*** Took care of three children during an emergency while his ankle was broken and they had to climb an elevator shaft.
347** Despite having the strength of ten men and the ability to calculate frankly incredible statistics in mere seconds, ''Series/StarTrekTheNextGeneration''[==]'s Lt. Commander Data is generally a nice, good-natured, pacifistic guy, and it takes a lot to get him riled due to the whole [[TinMan no emotions thing]]. Anyone who doubts his ability to totally kick ''ass'' when necessary, however, should really, really watch the episode "Descent I & II". And "Redemption". And "The Most Toys", for that matter. Seriously just... ''don't screw with him'', okay? Even Worf soon learns Data is not someone to cross lightly.
348--->'''Data''': I assume your handprint will open the door, whether you are conscious or not.
349** ''Series/StarTrekDeepSpaceNine'' hammers home that the Federation will not sit idly by while an enemy attempts to destroy them.
350*** Quark feels this way about humans, and by proxy the Federation itself. Sure, as a whole the human race is a pretty decent bunch, but that's only during peace time. Push them too hard and you'll have some of the nastiest hitters in the galaxy. The Federation is about peaceful coexistence, scientific research and exploration, but they explore with heavily-armed vessels that can stand toe-to-toe with the dedicated warships of their contemporaries, and despite outwardly decrying intelligence machinations, they have their Section 31, the Federation's very own Tal Shiar & Obsidian Order. S31 was willing to commit genocide when the Dominion threatened the security of the Alpha Quadrant. When the Federation finally built a dedicated warship, it was a tiny, spartan ''[[PintsizedPowerhouse escort vessel]]'', and it was capable of destroying much larger enemy warships.
351---->'''Quark''': Let me tell you something about Hew-mons, nephew. They're a wonderful, friendly people... as long as their bellies are full and their holosuites are working. But take away their creature comforts... deprive them of food, sleep, sonic showers... put their lives in jeopardy over an extended period of time... and those same friendly, intelligent, wonderful people will become as nasty and violent as the most bloodthirsty Klingon. You don't believe me? Look at those faces, look at their eyes...
352---->'''Nog''': I feel sorry for the [[ProudWarriorRaceGuy Jem']][[SuperSoldier Hadar]].
353*** One way to look at it could be to say that humans are, in the 'Trek century, a bunch of fairly genuine pacifists who would rather use words than weapons, but know that their weapons back up the force of their words. Then when enemies like the Borg come along and terrify the life out of us... well, then you get movies like ''First Contact''. Essentially, speak softly and pilot spacefaring death.
354*** In fact, there are exactly two civilizations known to have repelled a direct invasion by the Borg: [[StarfishAliens Species 8472]], and The United Federation of Planets. In their only military engagement, a single Federation starship [[CurbStompBattle absolutely]] ''[[CurbStompBattle curb stomped]]'' Species 8472. In a later episode, a member of that species would confirm that the incident caused them to view humanity as TheDreaded.
355*** Miles O'Brien. He is a devoted family man and seems like your average mild-mannered Starfleet engineer, but he's seen enough combat that Klingons acknowledge his tactical experience. In fact, in the episode in which he's ''legally'' recognized as an expert in starship combat by both the Empire and the Federation, nobody even blinks at the idea that he would have assumed command of the ''Defiant'' if Worf had been killed, even though he's not a commissioned line officer, but a senior enlisted chief specialist in the ''engineering division''. He's even able to improvise a stun grenade with his phaser that a BrainwashedAndCrazy ''[[MagnificentBastard Garak]]'' never saw coming.
356---->'''Ch'Pok''': For the record, Chief O'Brien has been in two hundred and thirty-five separate engagements, and Starfleet has decorated him fifteen times. I would like to have him declared an expert in the area of starship combat.\
357'''Admiral T'Lara''': Any objection?\
358'''Sisko''': None.
359*** Garak is uncompromisingly polite, highly cultured, an erudite speaker, and does not exude the military braggadocio that many of the Starfleet, Cardassian, and Klingon officers we see on the series do. However, Garak is an expert intelligence agent, willing to go well beyond what the military types see as acceptable conduct in order to fulfill his missions and goals. Garak is noted as an immensely skilled interrogator who doesn't need to rely on physical torture and assaults to unlock the secrets he desires. He is no slouch in combat, however. He once held up against Worf in hand-to-hand combat, and when required he will not hesitate to kill anyone who stands in his path, in the most efficient manner possible.
360** And ''[[Series/StarTrekVoyager Voyager]]'' gave us perpetual newbie and resident ButtMonkey Ensign Harry Kim...
361*** ...who in "The Chute" managed to hand beatdowns to hardened prison inmates in defense of his {{Heterosexual Life Partner|s}} Tom Paris, before finally snapping and turning on Paris himself. He was on aggression-enhancing drugs, but still.
362*** There was also his HeroicBSOD at the end of "Timeless," which resulted in [[spoiler:'''the successful destruction of an entire timeline''']].
363*** There was the way he almost single-handedly figured out how to fuck up the Hirogen occupation in "The Killing Game." And capped it off by telling them to [[DefiantToTheEnd go straight to hell]] when they figured it out.
364** ''Voyager'' also gave us Kes. The nicest girl you'll ever meet, but don't get on her bad side. A body-surfing warlord who had lived for ''centuries'' found out the hard way that an angry Kes is not someone you want to mess with.
365** In "Scientific Method", there's a group of aliens that have invaded the ship unbeknown to the crew and are using them to experiment on for new advances in medical science. Janeway, though, is treated to headaches so painful it's like having needles boring into her brain, which there are. The aliens wanted to see the result of making the sweet and controlled captain snap. The result: her taking the helm and flying near a star to destroy one of the alien ships attached to ''Voyager'', forcing the other to leave.
366--->'''Captain Janeway''': You wanted to see the result of making me angry? Well, here it is.
367** ''Series/StarTrekEnterprise'' gives us Malcolm Reed, a ShrinkingViolet who CannotTalkToWomen romantically and is on good terms with his shipmates. He's also in charge of making things go boom, and he's more than happy to do so.
368** Elnor from ''Series/StarTrekPicard'' is a naïve NiceGuy, a PluckyComicRelief... and a MasterSwordsman. Anyone who threatens his friends will receive exactly one warning to back off: "[[DontMakeMeDestroyYou Please, my friend(s). Choose to live.]]" Those who disregard this warning [[OffWithHisHead end up a head short]], after which he grimly says, "[[BondOneLiner I regret your choice.]]"
369*** This seems to be normal for the Qowat Milat (which Elnor technically isn't, since they're a female-only order). They practice BrutalHonesty and seek to help others, especially lost causes. On the surface, they look like an order of nuns, but their martial art and swordmastery skills are second to none.
370* ''Series/{{Supernatural}}'': Sam Winchester -- he's always got a kind word for someone shell-shocked from a brush with the supernatural, prefers to do research rather than pick locks and break faces, and will most certainly fuck you up if you even think about hurting his older brother. Just ask Gordon Walker [[spoiler:(beheaded with barbed wire)]] or the Crossroads Demon [[spoiler:(shot in the head)]].
371** [[OurAngelsAreDifferent Castiel]] may seem amusingly out of touch much of the time, but you really don't want to make him angry. Hell, not even Castiel's TrueCompanions are safe from this. At a perceived betrayal, Cas beats [[spoiler:Dean]] to within an inch of his life. Cas going off the rails is NOT a pretty sight.
372--->'''[[spoiler:Dean]]:''' Word of advice — don't piss off the nerd angels.
373* Many many ''Franchise/SuperSentai'' characters are perfectly friendly {{Nice Guy}}s, with some {{Jerkass}}es eventually revealed as [[JerkWithAHeartOfGold having a heart of gold]] along the way, but if they're pushed too far, massive ass-kicking ''will'' ensue. However, the one that claims this trope ultimately is Ryuuji Iwasaki/Blue Buster from ''Series/TokumeiSentaiGobusters''. He's a perfectly calm, genuine NiceGuy who serves as a TeamDad, but his weak point is when he overheated... in which he becomes utterly ''scary'', has a much more brutal, sadistic fighting style, will not stop even if the MonsterOfTheWeek is begging for mercy, until the monster is dead, and does not differentiate between friends and foe. When Yoko/Yellow Buster found out the hard way and nearly got her head squished to the wall even after believing their bonds would save the day (which was proven ''wrong''), she [[HeroicBSOD broke down crying in shock]].
374** Once, when facing Escape (one of the CoDragons) alone, he ''deliberately'' drove himself into his berserk state to become strong enough to win. That makes him cooler and scarier at once: don't push him, because ''every'' tool he has is on the table, even basically becoming the [[ComicBook/TheIncredibleHulk Hulk]] in a Ranger suit (with the risk of death if he stays in that mode too long!) [[BloodKnight This makes Escape decide he's interesting and want to fight him again]]; she becomes his personal enemy just because she considers him the only one good enough to be worth fighting.
375** Before Ryuuji, ''Series/TokusouSentaiDekaranger'' had Sen-chan/[=DekaGreen=], the resident [[TheSmartGuy Smart Guy]], overall being the calmest and most polite member of the team. But if you do nasty things to innocents in front of him, ScrewTheRulesIHaveConnections be damned, ''nothing'' will save you from his wrath. And there's the one time he beat the crap of an Alienizer who was planning to kill Umeko after playing with and making fun of her feelings, and would have ended him if it wasn't because Umeko showed up and did it herself.
376** The following series ''Series/MahouSentaiMagiranger'' would bring us Urara Ozu/[=MagiBlue=], known for being TheReliableOne and the loving, kind TeamMom... which means she's also one hell of a MamaBear and will make sure you experience absolute hell if you do anything to her family (including going up to physically punch you in the face). Even that aside, she has a tendency to suppress her own feelings, which means that once she boils over and hits the RageBreakingPoint, good luck. All of the family members agree she's the most terrifying of them all when angered.
377** Nobuharu Udo/Kyoryu Blue of ''Series/ZyudenSentaiKyoryuger'' may be the show's PluckyComicRelief but in battle, he's probably the most vicious fighter on the team. Within the first couple of episodes we see him shoot {{Mooks}} to death while they're struggling on the ground and stabbing them [[GroinAttack in the crotch]] with the nasty metal spikes on his shield.
378*** Daigo as well. Even the BigBad, Chaos, notes it in one episode: "Don't underestimate him. When he has that look in his eye, he is a force to be reckoned with."
379* ''Series/TerminatorTheSarahConnorChronicles'': Just about everyone who encounters the Connors ends up thinking that [[RobotGirl Cameron]] is an odd but otherwise docile girl. And she stays that way unless someone threatens the Connors. Then she shows them just why she is known as a Terminator.
380* Eric Forman in ''Series/That70sShow''. Frequently mocked for his lack of physical strength, one episode shows him [[CurbStompBattle kicking the shit out of a football fan]] who'd been harassing him throughout the game.
381* On ''Series/TheThinBlueLine'' Goody actually punches a skinhead for insulting Habib.
382* James May on ''Series/TopGear'' usually endures his co-presenters' antics with good humor, but when they really irritate him, he can be pretty mean. Case in point: In a challenge to buy cheap Alfa Romeos and enter them in a car show, May had carefully cleaned and polished his car and was using it to tow Richard Hammond's. After Hammond "accidentally" bumped into his car one too many times, May disconnected the tow rope without a word and left him stranded.
383** In the South American Adventure Special, James points out: 1) He is afraid of heights, 2) He doesn't like it when the others deliberately rear-end him, 3) they will be driving along a very narrow road adjacent to a very long drop, and 4) he is carrying a 3' long machete, which adds up to 10) [[spoiler:if one of them rear-ends him on that road, he will castrate the offending party]]. Then Jeremy rear-ends him accidentally, the great oaf...
384** Also Richard Hammond, just once, during the race to the North Pole, although whether he'd actually have gone through with it...
385* Cole in ''Series/Tracker2001''. His race is normally peaceful and nonviolent. He is friendly, caring and often a bit bumbling as he isn't used to being human. But harm Mel in any way, and you will pay for it. Killing isn't his nature, but he'll still beat you up for it. And in the case of the fugitives, he can make the extraction process slow and painful as he did with Rhee, the killer of his wife and child.
386* Stefan and Bonnie of ''Series/TheVampireDiaries''. They may be nice, caring, and compassionate, but don't mess with them and the people they care about.
387** Elena. She is nice, but don't harm anyone she cares about. She will show just how like the amoral [[EvilTwin Katherine]] she can be.
388* ''Series/TheWestWing'': President Jed Bartlet. Most of the time, a [[OurPresidentsAreDifferent charming, amiable and folksy]] man with [[BenevolentBoss genuine affection for his staff]] (and who is greatly respected and admired by them in return), with a keen intelligence and encyclopedic knowledge of trivia. However, in the second episode, terrorists shot down a US military medical plane with the loss of life of all on board, including Bartlet's personal physician, for whom he had a great deal of affection for. And a different side of Bartlet emerged:
389-->''[[[TranquilFury chillingly calm]]]'' I am not frightened. I am going to blow them off the face of the Earth with the fury of God's own thunder.
390** And pretty much all of the next episode revolves around Bartlet's increasing desire for his military aides to devise a plan which will [[DisproportionateRetribution literally wipe them off the face of the planet]], and his frustration when they tell him that this is neither practical nor politically desirable.
391** On a geo-political level, don't mess with people who are weaker than you, or President Bartlet will remind you that most of the world is weaker than the United States Military.
392** Don't disrespect people in The White House. If you do, make sure you don't do it in front of Charlie, or he'll slam you into a wall and verbally take your head off.
393%%* Both Justin and Harper from ''Series/WizardsOfWaverlyPlace'' have their moments.
394%% ** Mason is pretty nice, too, as long as you don't hit his buttons
395* Eric Gotts from ''Series/{{Wonderfalls}}'' was by far the nicest, least obnoxious, and least ridiculous of the main characters, but when his cheating ex-wife turned up, he was downright vicious to her, including throwing a glass across the room, narrowly missing her head.
396* In ''Series/WynonnaEarp'', Waverly Earp is literally the nicest person in town (there was a vote. She got a sash). But if you come at her family or friends, she will come in guns blazing (or just stab you in the brain with a pair of scissors).
