History BewareTheNiceOnes / LiveActionTV

*** 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.

*** Survive Cardassian's infamous torture

* ''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." and 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).

*** The Fourth Doctor is generally 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.

* Cole in ''Series/{{Tracker}}''. 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.

** Yuka Osada from ''Series/KamenRiderFaiz'' 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.

In [[Recap/DoctorWhoS13E5TheBrainOfMorbius "The Brain of Morbius"]] he kills Morbius's pet MadScientist with ''cyanide gas''.
*** 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.

* ''Series/GenV'': Cate is generally a nice person, but when she hears a classmate making fun of [[spoiler: her boyfriend's death]] in "God U." and she [[MindRape Mind Rapes him]] into hitting his own testicles with a baseball bat every hour. Later in "First Day" to perform oral sex on a flashlight, and orders him to put it [[AssShove up his ass]] afterward (which isn't shown onscreen).

* Rommie in ''Series/{{Andromeda}}''. A nice polite and considerate young woman who just happens to be able to blow up a planet.

** 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?

** 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]]. ''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).

* ''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.

* Yuka Osada from ''Series/KamenRiderFaiz'' 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.
* ''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.
* In ''Series/KamenRiderGeats,'' several of the main characters fall into this trope.
** While [[Characters/KamenRiderGeatsAceUkiyo 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.
** [[Characters/KamenRiderGeatsKeiwaSakurai 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.]]
** [[spoiler:[[Characters/KamenRiderGeatsProtagonists 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.'']]

* 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 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]]

** 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 put into a coma in "[[Recap/BuffyTheVampireSlayerS2E1WhenSheWasBas When She Was Bad]]"]], to Buffy: "If Willow dies, I will kill you."

** The Vulcans in general have this going on. They are polite, intelligent, and calm (if not a bit cold and stiff) 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.

** [[Characters/KamenRiderGeatsKeiwaSakurai Keiwa Sakurai]] is one of if not the most good-natured and caring Rider of the series. After 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.

** While [[CharactersKamenRiderGeatsAceUkiyo 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.

** [[spoilers:[[Characters/KamenRiderGeatsProtagonists 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.'']]

* In ''Series/KamenRiderGeats'', Keiwa Sakurai is the most good-natured and caring Rider of the series. After 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.

* Roy Desoto from ''{{Series/Emergency}}'' could fall into this at times. He was normally pretty easy to work with and get along with, but he would not hesitate to call someone out if they started trying to take things further than their training and patients got endangered. The main case was a CombatMedic who thought his battlefield training made him better than Roy and John. Roy never actually yelled, but he got a deadly serious look in his eyes and gave the guy a serious talking to with a tone that made it clear that was one of his angriest moments of the series. Not that it did much good.

** 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). 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!

** 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 [[HundredPercentAdorationRating 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…]]

** Before them, ''Series/TokusouSentaiDekaranger'' had Sen-chan/Deka Green, 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.
** The following series ''Series/MahouSentaiMagiranger'' would bring us Urara Ozu, 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.
