* The Trinity siblings/Gundam Thrones of ''[[Anime/MobileSuitGundam00 Gundam 00]]''. Michael is AxCrazy, Nena's CuteAndPsycho, and Johann is TheStoic: they believe they are creating a better world... despite the fact [[KnightTemplar they attack non-active militants and innocent civilians]]. As do the protagonists, for that matter, only they at least ''try'' to involve the civilians less.
%%* The hero's three sisters in ''Manga/{{Magikano}}.''
%%* ''[[Anime/AfterWarGundamX Gundam X]]'''s Frost Brothers, Shagia and Olba.
%%* The Toguro Brothers from ''Manga/YuYuHakusho''.
%%* The ''Manga/RozenMaiden'' dolls.
* ''Manga/RanmaOneHalf'':
** The Kunos are all totally bonkers.
** In the manga (the story wasn't converted to the anime), it's revealed that having NoSenseOfDirection is something that runs in Ryoga's family -- his mother and father are just as bad as he is.

* ''Manga/{{QED}}'': Touma's family are in general {{Cloudcuckoolander}}s and are geniuses in one field or another.
* Though we've only seen the female half of the Saginomiya family in ''Manga/HayateTheCombatButler'', they're all pretty well {{Cloudcuckoolander}}s. Isumi is the closest one to sane, and she barely qualifies as such.
** Isumi's grandmother mistakes her daughter, Isumi's mother, for Hayate when meeting him for the first time. And the mother thinks she actually is! Even wondering where she went when the grandmother changes paths.

* ''Literature/{{Oreimo}}'': Both Kirino and Kyousuke are {{Tsundere}} in their own ways. However, both of them ''clearly'' get it from their father.
* Shinichi's father in ''Manga/CaseClosed'' is a mystery writer who doesn't investigate because he's BrilliantButLazy. Fellow detective Heiji's father is a well-known police investigator. Haibara's parents are scientists. Ran's parents were highly proficient in martial arts.
* ''Manga/{{Inuyasha}}'': {{Youkai}} view compassion for [[ToServeMan humans]] as eccentricity at best and [[LoveIsAWeakness weakness]] at worst. Even the great Dog Leader was brought down by his compassion, an "infection" Sesshoumaru blames Inuyasha's human mother for even though Myouga states he was genuinely compassionate. Eventually, even Sesshoumaru succumbs to the family "curse" causing his mother to observe he's turned into his father.

* In ''Literature/ThePetGirlOfSakurasou'', Chihiro uses this to explain away resident IdiotSavant Mashiro's behaviour, and [[ThereAreNoTherapists did not suspect the latter]] [[WordOfDante may have some kind of mental disability]].

** Luffy and his father [[spoiler:Dragon]] are the only known people to have [[spoiler:'''declared war upon the World Government''']] and gotten away with it. Completely unrelated to each other. [[spoiler:Dragon]] is also leading an active rebellion.

** Those who have D as a middle initial have a tendency to GoOutWithASmile, which is called the "Will of D". So far, the only exception is Marshal D "Blackbeard" Teach, which Whitebeard takes to mean that Teach is ''not'' a true inheritor of the Will. However, it's unclear just how the various D's are related.

* ''Literature/{{Baccano}}'''s Laforet family is a proud family line consisting of {{Mad Scientist}}s, [[PsychoKnifeNut knife-wielding]] [[LoveMartyr fanatics]], {{Enfante Terrible}}s and, [[spoiler:once Claire finds his way into the bloodline]], [[TheAce hypercompetent]] [[InsufferableGenius but insufferably arrogant]] solipsistic teenage girls. Only one can arguably be considered reasonably sane (Luchino Campanella), and he's a teenage assassin.

* In ''Manga/MagicalGirlLyricalNanohaVivid'', when Einhart relates what GeneticMemory she has of Wilfried Jeremiah and mentions the part about Reid [[TheDrifter coming and going for long periods of time]], Victoria snarks that Sieglinde seems to have inherited that trait from her ancestors. Victoria also mentions that the Jeremiahs are a nomadic tribe, which helps explain this tendency of theirs.
* Loz, Yazoo, and Kadaj from ''Anime/FinalFantasyVIIAdventChildren''. Like their father, they all want to help their mother Jenova in whatever they can. If that includes threatening dormerly {{Corrupt Corporate Executive}}s, kidnapping children, and summoning a dragon to destroy a city, all the better!
* PlayedForLaughs in one chapter of ''Manga/{{Horimiya}}'' when Miyamura ends up getting asked the exact same question by Hori, her father, and her brother in rapid succession. The inside cover of volume 10 shows that they've actually started rubbing off on him due to how much time he spends at their house.
* In addition to their good manga-drawing skills, the two Nozaki brothers in ''Manga/MonthlyGirlsNozakiKun'' also appear to have the same poor logic when following manga advice. This is evident when they try to follow Miyako's advice on cutting off the conversation on the bottom corner of the left page[[note]]remember that Japanese books are read right to left[[/note]] to draw readers in, and they both choose to cut off mid-word. Miyako snarks that reading Nozaki's manga do this correctly and then switching to Mayu's failed attempt at this makes it feel like Nozaki's version was her imagination.
* ''Manga/FruitsBasket'':
** As much as she hates her AbusiveMom Ren, Akito is [[YouAreWhatYouHate just like her]]: a {{Yandere}} PsychopathicWomanchild who is obsessed with proving that only she deserves to be loved by the Sohma men and gets insanely jealous over other women who "steal" their attention. If it hadn't been for Akito having [[HeelFaceTurn a change of heart]] because of Tohru [[BecauseYouWereNiceToMe offering her friendship]], Akito would have ended up as a solitary crazy lady like Ren.
** Kyo picked up many unpleasant traits from his {{Jerkass}} father; he has an IrrationalHatred of Yuki just as his father does him, and also [[NeverMyFault blames Yuki]] for all of his problems just as said father blames Kyo for all of his own. [[LikeFatherUnlikeSon Unlike his father, however]], Kyo [[CharacterDevelopment eventually learns]] to let go of his hatred and accept responsibility for his own actions.

* The River family from ''Webcomic/IrregularElis''. A Spanish webcomic about a BadassFamily of [[{{superhero}} Superheroes]] with a lot of Creator/HannaBarbera influences.

* In ''Webcomic/GirlGenius'' Spark, which might be better known as ScienceRelatedMemeticDisorder, tends to run in families. It's probably the most apparent in the Heterodynes, a house full of powerful Sparks and vicious warlords who terrorized Europa for centuries.

* ''Manga/FullmetalAlchemist'': '''THE [[LargeHam LARGE HAMMINESS]], [[IdiotHair IDIOT HAIR]], artistic skills, [[CharlesAtlasSuperpower CHARLES ATLAS SUPERPOWER]], AND [[BishieSparkle SPARKLES]] HAVE BEEN PASSED DOWN THE ARMSTRONG FAMILY LINE FOR ''GENERATIONS!!!!'''''

* ''Manga/FullmetalAlchemist'': '''THE [[LargeHam LARGE HAMMINESS]], [[IdiotHair IDIOT HAIR]], [[CharlesAtlasSuperpower CHARLES ATLAS SUPERPOWER]], AND [[BishieSparkle SPARKLES]] HAVE BEEN PASSED DOWN THE ARMSTRONG FAMILY LINE FOR ''GENERATIONS!!!!'''''

** [[spoiler:Edgeworth]] is a good example of this as well in the fourth cases of ''PhoenixWrightAceAttorneyTrialsAndTribulations'' and the first ''AceAttorneyInvestigationsMilesEdgeworth'' game. The outfit is ''very'' similar to Manfred's, and the finger wag is shared by both.

The ProfessionalWrestling version of the trope is, of course, WrestlingFamily. Contrast TurnOutLikeHisFather. Compare SharedFamilyQuirks.

A family full of eccentric, weird, sometimes insane relatives. Preferably all of them, but as long as it's the majority of them then it's okay. Commonly it's all of them except the OnlySaneMan or the BlackSheep.

Someone may observe their..."activities," but when they confront the family about this, the said family will often have no idea that they are considered to be out of the ordinary.

Some fans have even [[WMG/PoisonOakEpilepticTrees theorized]] that [[{{Squick}} his parents are brother and sister]] due to this.

* ''Manga/The100GirlfriendsWhoReallyReallyReallyReallyReallyLoveYou'': Exaggerated in Chapter 144, which reveals that every member of Karane's family is a {{Tsundere}}. In the span of 2 pages, Rentarou is introduced to four generations of Inda and each and every one of them, from the eldest of elders to the babyest of babies, is greeting Rentarou with some form of "It's not like I'm glad to meet you." They also look very similar, sharing the same sharp eyes.

As do the protagonists, for that matter, only they at least ''try'' to involve the civilians less.

** Anyone, ''anyone'', in who is in any way related to the Kiharas can be easily identified not only as evil scientists, but as batshit insane, downright monstrous evil scientists.

* ''Manga/{{Inuyasha}}'': {{Youkai}} view compassion for [[ToServeMan humans]] as eccentricity at best and [[LoveIsAWeakness weakness]] at worst. Even the great Dog Leader was brough down by his compassion, an "infection" Sesshoumaru blames Inuyasha's human mother for even though Myouga states he was genuinely compassionate. Eventually, even Sesshoumaru succumbs to the family "curse" causing his mother to observe he's turned into his father.

* In ''Manga/ServantXService'', as Yutaka Hasebe's sister Kaoru mentioned, the entire Hasebe family are (1) civil servants and (2) share extreme BrilliantButLazy / TheSlacker traits. Yutaka, who as at first seen as a loser if not for his HiddenDepths, is indeed the ''most downplayed'' in terms of this trait.

** ''ComicBook/{{Deadpool}}'', a SociopathicHero, hooks up with Shiklah, an evil [[SuccubiAndIncubi succubus]] who's crazier than he is. Both have shown an attraction to one another's violent sides. Their relationship was as stable as one could expect. They can be lovebirds one minute , and literally going to war with one another the next, while having sex in the middle of that. They have a daughter together sometime in the future. Needless to say their daughter, Warda is just as violent as both of her parents. She doesn't have a high opinion of Deadpool, held him hostage and tortured him for years trying to get info on what he'd done with Shiklah, while also causing another war. Deadpool's first child, Ellie, fights against her. While Ellie isn't as crazy as Deadpool or her half-sister, she is not shy to solving problems through violence. Even as a kid, she got into many fights after changing schools, with Deadpool encouraging her to tell teachers about bullies, instead of fighting. But no luck.

** A page in the comics describes the Creeplys as direct descendants of the Gruesomes and states that, like their ancestors, like gloomy weather, ants at picnics and monster movies where the monster wins and hate rock music.

* In ''Fanfic/BlackkatsReverse'', Sarutobi is quickly persuaded that Uzumaki Kurama really is a Uzumaki, for the good reason he left an unholy amount of trouble in his wake.
* In ''WesternAnimation/DannyPhantom'' fanfic ''Fanfic/{{ResurrectedMemories}}'': One of the earliest hints that Ember is [[spoiler: related to the Murray family is the fact that they tend to have an affinity to music with Ember being an EvilDiva prior to a HeelFaceTurn, Mrs. Murray, aka Ember's [[LongLostRelative long lost little sister]] being a music teacher and Zoe, Mrs. Murray's older daughter not only having a band she is putting together but also goes to an arts school as a music student.]]

* Name-dropped by Feral in ''Fanfic/RunningWithLightningFeet'' when Wolffe accuses him from being a drama queen. Since Maul enjoys his BigEntrance, Savage tends to slaughter everything in his path and Feral just made a huge scene asking to be killed, it's hard to disagree.

** The second is music. Manolo has an ancestor several generations back who wanted to be an opera singer but was pushed into bullfighting. As such, he sympathizes with Manolo, and even gets one heck of a solo in the big final battle. (Fittingly, he is voiced by Placido Domingo!)

* ''WesternAnimation/{{Coco}}'': Subverted and played straight. Miguel's family have been well-known shoemakers for nearly a century, but Miguel himself is far more interested in becoming a musician. On the other hand, his great-great grandfather was a talented musician, with Miguel taking more after him than the other members of his family. The climax and ending of the film reveal that the musical gift was more widely spread than was initially thought, as not only is Mama Imelda, Miguel's great-great grandmother and the one who instituted the "No Music" policy, an amazing singer, but Miguel's cousins who previously belittled him for his musical interests are also playing instruments at the following year's Día de Muertos.

** His great uncle was a preacher who grew his mole hairs "to cleanse is soul" and believed a sea monster stole the sherrif's cow.

* Averted in ''Film/BigGame''. Oskari ''wishes'' that he was as good a hunter as his father and rest of his family is.

* The title family in ''Literature/TheBagthorpeSaga''. Tess, Rosie and William are all somewhat eccentric, and their parents and grandparents might edge into mildly deranged, as might their cousin Daisy... They all (well, except Daisy) believe wholeheartedly in their genius as a family and individually, and take themselves very seriously. In one of the books in the sequence, they try to break as many Guinness World Records in a summer as they can... And in keeping with the trope, Jack and his ally Uncle Parker are the only sane ones people can bear to have anywhere near them. Also Grandpa (though he's less developed as a character).

* {{Subverted|Trope}} in the ''Series/DoctorWho'' Literature/EighthDoctorAdventures novel ''The Taint'': Fitz's maternal relatives are mostly more or less insane. It turns out it's due to alien brain slugs, which the Doctor deals with. It seems, however, that Fitz has a slightly different view of matters, as in one or two later stories, he thinks he's hallucinating and blames it on the craziness that runs in his family, even though he hasn't got a brain slug any more. Naturally, he's not hallucinating.

* ''Literature/TheDinner'': [[spoiler:Paul suffers from a neurological disorder that makes him prone to violent behavior. Michel's murderous actions make Paul wonder if his son has inherited that disorder, though its also implied that Michel could simply have been psychologically influenced by Paul outside of genetics.]]

* ''Series/BuffyTheVampireSlayer'': A gift for banter and sarcasm runs deep in Summers women, as shown by Buffy, her sister Dawn and their mother Joyce along with courage, toughness and great beauty.

** The Pond family is smaller than most examples, but has more wackiness than most small planets. Poor Rory seems to be the OnlySaneMan[[note]]Though you would be too if you had 2000 years of memories of protecting Amy and nothing can scare you any more[[/note]], as his wife spent her childhood biting psychiatrists, his daughter is a self-proclaimed psychopath, and his son-in-law puts the "crazy" in CrazyIsCool.
** In the ''AudioPlay/BigFinishDoctorWho'' and ''AudioPlay/{{Gallifrey}}'' audios, the Doctor's relatives Brax, Susan, and Alex[[note]]respectively his brother, granddaughter and great-grandson[[/note]], have a habit of being reckless, independent, highly intelligent, and self-sacrificial. [[spoiler:The latter costs poor Alex his life when he is only twenty years old.]] Special mention goes to Brax for also having a tendency to lie to his friends to keep them safe. Sound familiar?

* Music/AmandaPalmer's "Runs in the Family" describes people who have inherited various complications and illnesses from their bloodlines and goes on to talk about what the singer believes to have inherited from their family (namely their impulsiveness, traumas and fear of consequences).

* A fairly minor case PlayedForLaughs in Roleplay/DinoAttackRPG. Sarah Bishop gained a particular infamy among the cast when she became the first known person to hate the [[SupremeChef Brickolinis']] pizza (though Pierce ''might'' also count, or he may just have eaten a particularly hot one). Sure enough, a few posts later, it turns out her daughter Kate can't stand the taste of Brickolinis' pizza either.

* The d'Ambrevilles of Glantri in the TabletopGame/{{Mystara}} D&D setting are a large and fractious family of wealthy, self-indulgent, scheming and often magically-gifted weirdos. They were even stranger in the adventure (Chateau d'Ambreville) that introduced them, having been trapped in a bizarre PocketDimension for years; many had turned single rooms or suites within their cursed mansion into their own private gardens/laboratories/banquets/whatever, and had been physically transformed by curses to have the heads of animals.

* ''VideoGame/MassEffectAndromeda'' reveals that Conrad Verner (obsessive Shepard fanboy) and his tendencies aren't just limited to him. His sister Cassandra is an even ''bigger'' nutcase than her brother. Conrad at least worships an actual hero, not a ruthless crime-lord.

** [[spoiler:Edgeworth]] is a good example of this as well in the fourth cases of ''PhoenixWrightAceAttorneyTrialsAndTribulations'' and the first ''AceAttorneyInvestigationsMilesEdgeworth'' game. The outfit is ''very'' similar to Manfred's, and the fingerwag is shared by both.

* In ''WesternAnimation/AvatarTheLastAirbender'', the royal family of the Fire Nation have a tendency to be sociopathic nutjobs. For some odd reason it only seems to happen to one family member per generation, unfortunately, until the last two generations that one person was the eldest son. Zuko seems to have put a stop to it for good by the time of ''WesternAnimation/TheLegendOfKorra'' because his SpinOffspring are well adjusted, good folks.

* In ''WesternAnimation/MiloMurphysLaw'', the titular character is a direct descendant of Edward Aloysius Murphy Jr. (of whom "Murphy's Law" is named after)--both Milo and his dad, Martin, [[TheJinx have a tendency for bizarre and unfortunate thngs to them and the people around them]]. But just like the "Simpson Gene" mentioned above, this tendency for bad luck appears to only affect the male descendants of Edward A. Murphy Junior (i.e., Milo has an older sister who doesn't have a tendecy for bad luck like her dad and brother do).

A family full of eccentric, weird and sometimes insane relatives. Preferably all of them, but as long as it's the majority of them then it's okay. Commonly it's all of them except the OnlySaneMan or the BlackSheep.

* ''Manga/The100GirlfriendsWhoReallyReallyReallyReallyReallylLoveYou'': Exaggerated in Chapter 144, which reveals that every member of Karane's family is a {{Tsundere}}. In the span of 2 pages, Rentarou is introduced to four generations of Inda and each and every one of them, from the eldest of elders to the babyest of babies, is greeting Rentarou with some form of "It's not like I'm glad to meet you." They also look very similar, sharing the same sharp eyes.

** [[spoiler: Edgeworth]] is a good example of this as well in the fourth case. The outfit is ''very'' similar to Manfred's, and the fingerwag is shared by both.

** Everyone -- ''everyone'' -- on the show arguably [[spoiler: goes insane]] by the end, but the Emperor's line is the most [[IncrediblyLamePun screwy]] of all, in both mind and manipulation.

* ''LightNovel/{{Oreimo}}'': Both Kirino and Kyousuke are {{Tsundere}} in their own ways. However, both of them ''clearly'' get it from their father.

* In ''LightNovel/ThePetGirlOfSakurasou'', Chihiro uses this to explain away resident IdiotSavant Mashiro's behaviour, and [[ThereAreNoTherapists did not suspect the latter]] [[WordOfDante may have some kind of mental disability]].
