History Main / IfYouEverDoAnythingToHurtHer

* ''Fanfic/TransformersMHA'': After noticing how Denki and Ibara have a thing for each other, Setsuna makes it clear to Denki that if he so much as hurts Ibara then he'll have to answer to her.

* ''[[https://archiveofourown.org/works/42198018/ Harry Potter and the Ritual of Love's Memory]]'': Charlie's letter to Ginny is ''mostly'' supportive and congratulatory of her new relationship with Harry.

* In ''[[https://m.fanfiction.net/s/10264509/228/Tales-of-Fairies The Gender Bend Cliche]]'', Gajeel, who came to see his fellow dragon slayer [[GenderFlip Natsu]] [[LikeBrotherAndSister akin to family]], tells Luca that if he breaks her heart then he'll break his face. Luca dryly remarks it rather [[HypocriticalHumor hypocritical for Gajeel to warn him about hurting Natsu given that months ago he tried to beat her to a pulp]].

---> '''Charlie''': Look -- I'll say it just in case no one has spelled it out for you. You hurt her, I can hold a human-to-beef transfiguration long enough for a Horntail to digest the evidence. I'm not taking the piss here, either. No. Evidence.\\
'''Harry''': If I deserve it, you'll have to beat her to it. There's a trophy over the hearth you should look at.

* A non-dating example happens in ''[[https://www.fanfiction.net/s/13592324/7/Danny-Phantom-vs-American-Dragon-Jake-Long-The-Novelization Danny Phantom vs American Dragon: Jake Long: The Novelization]]''. Sam Manson distrusts Jake Long after hearing that he tried to kill Danny despite being aware that they're under a spell that increases their aggression, and attempts to warn Jake of what she'll do to him if he hurts Danny. [[SurprisinglyRealisticOutcome Jake isn't remotely intimidated because Sam is a normal human while he's a dragon,]] and he even mocks her for it.

* ''Fanfic/ChildOfTheStorm'': Subverted in the finale of the first book when Magneto turns up and sees Harry Dresden, who is now dating his daughter, Wanda. Dresden, knowing what's coming and Magneto's reputation tries (and being six foot nine, fails ''miserably'') to hide behind her. Wanda, however, cuts him off with - "Father, don't you dare." Magneto just acquiesces in amusement, noting that the fact that Dresden isn't John Constantine is a mark in his favour.

* Charlie Weasley aims one at Harry himself in ''Fanfic/HarryPotterAndTheNightmaresOfFuturesPast''.

* In ''Film/WeTooTogether'', Gabriela's brother Alexander takes this trope to an extreme. He doesn't want his sister dating an autistic guy, and gives Rob the usual speech about how he'll kill him if he hurts her. Then he invites Rob into his car and starts driving fast in order to intimidate him. Later, he even shows up at Rob's dojo with some goons to beat him up, but Rob defends himself without much difficulty. Then Gabriela arrives and orders them to stop fighting, after which they form an easy truce.

* In ''[[https://www.fanfiction.net/s/13165279/19/Harry-Potter-and-the-Rule-of-Three Harry Potter and the Rule of Three]]'', Harry, Hermoine, and Susan have decided to be a trio.

She does calm down when Hermoine and Susan explain some context Fleur wasn't aware of, and it's all settled cordially.

* ''WesternAnimation/KimPossible'': When Kim Possible and Ron Stoppable start dating (thanks to some encouragement from the Moodulator) in the s3e2 Episode "Emotion Sickness," Kim's dad warns him that he'd better not make Kim unhappy.
-->'''Mrs. Dr. P:''' We want Kim to be happy.
-->'''Ron:''' We do.
-->'''Mr. Dr. P:''' If not, it's a one-way ticket on a deep-space probe.
-->'''Ron:''' H-how deep?
-->'''Mr. Dr. P:''' ''Black hole deep'', [[FullNameUltimatum Ronald.]]

'''Paulina's Dad''': If you upset her… [[CurbStompBattle We're going to have a]] ''[[CurbStompBattle violent talk]]''.\\

* ''Series/GoodOmens2019'': Played straight with [[OurDemonsAreDifferent Crowley]], because he is [[OneTrueLove very protective]] towards [[OurAngelsAreDifferent Aziraphale]]. Especially in season 2, when he repeatedly threatens [[spoiler:amnesiac]] archangel [[OurAngelsAreDifferent Gabriel]]:

-->[[spoiler:amnesiac]]'''Gabriel:''' No. Or yes. Or.. no.

* Since parental threats are allowed, we ''can't'' forget (president) Jed Bartlet's on ''Series/TheWestWing'':

::
:: And he ''likes'' Charlie!

* In ''Series/{{Psych}}'' Lassiter has an epic moment delivering one of these. At first unwilling to accept that Juliet was dating Shawn, he eventually closed himself and Shawn in a small room, hooked ''himself'' up to a [[LieDetector polygraph]], and then said that if Shawn screwed up he would shoot him. Cut to the polygraph needle showing that he is telling the truth.

* in the ''{{Series/Bones}}'' fic ''[[https://archiveofourown.org/works/576365 Love In Farsi]]'' Booth finds the poetry book Arastoo gave Cam and proceeds to tell him, in Farsi, just what he’ll do if Arastoo hurts can. In involves gutting him and making him a eunuch. Ouch.

->''"I've never seen my sister this happy, Ian. If you hurt her, I'll kill you and {{make it look like an accident}}."''
