[[AC:''Franchise/SpiderMan'']]
* In ''Fanfic/UltimateSpiderWoman: Change with the Light'', Ben Reilly's parents both hate Mary Jane Watson and are fairly open about it, especially when [[BoyfriendBlockingDad Andrew]] outright ''threatens'' Mary Jane if she doesn't stop dating his son. When he finds out about it, Ben is not amused.

[[AC:''Franchise/{{Superman}}'']]
* ''Fanfic/TheUnfantasticAdventuresOfBizarroNo1'' has Bizarro say he could forgive the [[ManOfKryptonite Blue-Kryptonite Men]] for attempting to wipe his race out if they had started with mothers-in-law.

* In ''Fanfic/UltimateSpiderWoman: Change with the Light'', Ben Reilly's parents both hate Mary Jane Watson and are fairly open about it, especially when [[OverprotectiveDad Andrew]] outright ''threatens'' Mary Jane if she doesn't stop dating his son. When he finds out about it, Ben is not amused.

* [[Deconstructed DeconstructionFic]] in ''Foob's Paradise'': Mira is well intentioned, but has a tendency to talk without listening and focus on [[SkewedPriorities the wrong issues]], such as addressing her daughter's lack of organization in the kitchen when Deanna's on the verge of breaking down from stress. Due to this, everyone tends to ignore her even when she's got genuine concerns. After Wilf talks to her about it, Mira starts making an effort to pay more attention and offer legitimate advice.

* ''Fanfic/TheManyDatesOfDannyFenton'' In the alternate ending where Danny chooses [[spoiler:[[WesternAnimation/ScoobyDooAndTheGhoulSchool Phantasma]], Danny would have this kind of relationship with Phanty's father, one of mutual and utter contempt]].

* In ''[[http://archiveofourown.org/works/8793565/chapters/20159878 How the Light Gets In]]'', Laurel's parents hate [[Series/{{Supernatural}} Dean]], her father largely because he thinks Dean isn't good enough for her and recognizes Dean's basically a criminal, while her mother blames Dean for strained her relationship with Laurel is ([[NeverMyFault smoothly ignoring that's her own fault]]). Dean isn't very fond of them either. However, he adores Laurel's grandmother and his relationship with Sara is dysfunctional but still relatively loving.

* In ''Fanfic/UltimateSpiderWoman: Change with the Light'', Ben Reilly's parents both hate Mary Jane Watson and are fairly open about it, especially when [[OverprotectiveDad Andrew]] outright ''threatens'' Mary Jane if she doesn't stop dating his son. When he finds out about it, Ben is not amused.
* In the 'In My Eyes' stories latest chapter, Megatron outright says he'll kill [[spoiler: Sarah if she doesn't break up with Will.]]
* ''FanFic/TheNewRetcons'':
** Wilf and Mira regard [[ComicStrip/ForBetterOrForWorse the Pattersons, barring April]] as this, increasingly justified in Elly and John's case as the former goes insane and the latter refuses to do anything about it. Even at the best point in their relationship Mira can muster no more than indifference to her son-in-law Michael. [[spoiler: As a result, April's the only one Mira expects to have a relationship with when Deanna's divorce with Michael is finalized.]]
** Conversely, the Pattersons (again barring April) view Mira as this, particularly Elly, who feels she's usurping ''her'' position in the family.
* In the ''VideoGame/TeamFortress2'' fic ''[[https://www.fanfiction.net/s/8605925/1/ I'll Be Home for the Holidays]]'' the RED Sniper's brother-in-law, Jack Williams, is a thoroughly obnoxious and unpleasant person who gossips about Sniper behind his back and is revealed to have bullied him when they were children. [[spoiler: The worst of his KickTheDog moments comes when he wrecks Sniper's relationship with his father, which is finally beginning to heal, by revealing Sniper's rifle to his father and showing that he isn't a doctor as he was pretending to be]]. One wonders why Sniper's sister, Lizzie, [[WhatDoesSheSeeInHim even married him in the first place.]]
* Mr. Satou to [[VisualNovel/KatawaShoujo Hisao]] in ''Fanfic/LillyEpilogueFamilyMatters'', who doesn't think much of Hisao, Hanako, or [[spoiler: Lilly's decision to remain in Japan]]; he is such a {{Jerkass}} that he outrages his older daughter Akira, [[spoiler: and eventually, Lilly loses her temper and throws him out of the apartment]]. [[spoiler: Ultimately, however, he relents, apologizes to Lilly, and gives Hisao his approval]].
* In ''Fanfic/CodeGeassThePreparedRebellion'', the usual dynamic is inverted. Reuben Ashford is continuously vexed by his daughter-in-law Melisande's attempts to replace him as head of the family.
* In the ''VideoGame/TeamFortress2'' fanfic ''Fanfic/SomethingNew'', Sophia's [[spoiler: adoptive]] parents absolutely cannot stand Liam due to him being a "thug from Southie." The way they treat their daughter, however, [[AbusiveParents isn't that much better]].
** On the flip side, Sophia gets along relatively well with Liam's mother Colleen.

* ''Fanfic/WhereTalentGoesToDie'' alludes to this trope when Yuuki notes that [[TheLeader Mitamura]], who's serious to a fault and [[EtiquetteNazi a stickler for good manners]] and [[GrammarNazi grammar]] is trying to be like "the mom of our group," but in practice, ends up as the "mother-in-law." As unflattering as the analogy is, Yuuki actually likes Mitamura, respects her intelligence, and hopes to become friends with her.
** Downplayed with Kaori's paternal grandmother, who dislikes Kaori's mother. Despite their fundamentally incompatible worldviews- Kaori's grandmother [[StayInTheKitchen is a highly traditional housewife]], while Kaori's mother works outside the home- Kaori's mother treats everyone with respect, so the two women can at least keep things civil.

* ''Fanfic/TheUnfantasticAdventuresOfBizarroNo1'' has Bizarro say he could forgive the [[ManOfKryptonite Blue-Kryptonite Men]] for attempting to wipe his race out if they had started with mothers-in-law.
* In ''Fanfic/DoctorGhemorIPresume'', Legate Tekeny Ghemor is rather upset to learn his (possible) son is courted by Garak, formerly a ruthless spy and torturer blindly loyal to a man even worse. On Garak's side, he's terrified by the possibility of Ghemor discreetly assassinating him.
** Then Garak meets his husband's human parents. He immediately takes umbrage at them verbally and emotionally abusing Julian, and they take offense at Garak defending Julian from them.
* Paul Blofis' parents in ''[[https://www.fanfiction.net/s/7821579/10/The-Moments-of-Paul-and-Percy The Moments of Paul and Percy]]'' are this to Sally Jackson. Sally is horrified when Paul's mother, who is described as the stereotypical mother-in-law, suggests that the family move into the house across from theirs.

* Deconstructed in ''Foob’s Paradise'': Mira is well intentioned, but her problem is both that she talks without listening and focuses on the wrong issues, such as her daughter’s lack of organization of the kitchen when she’s on the verge of a breakdown from stress. This makes everyone not fully listen to her when she has genuine concerns. After Wilf talks to her about it, Mira starts actually listening and giving legitimate advice.

* In ''Fanfic/UltimateSpiderWoman: Change with the Light]]'', Ben Reilly's parents both hate Mary Jane Watson and are fairly open about it, especially when [[OverprotectiveDad Andrew]] outright ''threatens'' Mary Jane if she doesn't stop dating his son. When he finds out about it, Ben is not amused.
