* The Kunos in [[RanmaOneHalf Ranma 1/2]] 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. Some fans have even [[PoisonOakEpilepticTree theorized]] that [[{{Squick}} his parents are brother and sister]] due to this.
* [[spoiler: Father and son Isshin and Ichigo Kurosaki]] in ''{{Bleach}}''

* ''CodeGeass'' 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. This troper cannot start listing examples, simply because everyone is an example.

** Isumi's grandmother mistakes her 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.
* FullmetalAlchemist: THE [[LargeHam LARGE HAMMINESS]], [[CharlesAtlasSuperpower SUPER STRENGTH]] AND THE [[BishieSparkles SPARKLES]] HAS BEEN PASSED DOWN FOR GENERATIONS!!!!

The River family from ''{{Irregular Elis}}''. A spanish webcomic about a [[{{Badass Family}} Badass Family]] of [[{{superhero}} Superheroes]] with a lot of Hanna-Barbera influences.

-''"I went back to my mother. I said, "I'm crazy, Ma. Help me." She said, "I know how it feels, son. 'Cause it runs in the family."''

* HOW have we gotten this far without mentioning ''CodeGeass''? 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. This troper cannot start listing examples, simply because everyone is an example.

* The Trinity siblings/Gundam Thrones. of ''{{Gundam 00}}'' Michael is AxCrazy, Nena's a {{Yandere}} 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.

* LazyTown's Stephanie is the only character in the show who has bright pink hair. But according to her uncle, it's a trait that runs in the family.

* The Kunous in [[RanmaOneHalf Ranma 1/2]] are all totally bonkers. Arguably also the Tendos but in a much lesser way.

* As does being a Shinigami, as [[spoiler: Father and son Isshin and Ichigo Kurosaki]] in ''{{Bleach}}''

**** Your all forgeting about the Mother's Side of the Family! Jenova likes to imitate Dead People, then MindRape anyone who's fooled by them so she can make them do her bidding so she can Eat the Planet's Lifestream! Too bad she's crippled and has to rely on her kids and husband to do all the dirty work after being smashed by a Meteor herself.

* Inverted in ''{{A Series Of Unfortunate Events}}'': the Baudelaire siblings are the only people who aren't insane, evil, or completely oblivious.

* Arguably, The Weasleys from ''HarryPotter'' are one big kooky red-headed family who are implied to be quite old and presumably extensive, as females are very rare in their line. There's only one Squib, who Ron reveals to be an accountant.

* ''{{The Addams Family}}''.
* ''{{Arrested Development}}'' is about a family that has no idea how to live conservatively and act like decent human beings....except for Michael Bluth, who the family both counts on to keep them afloat and takes for granted.
* {{The Munsters}} are all members of the {{Monster Mash}} and are considered weird... except for human-looking Marilyn - who was considered ugly by the rest of her family (though she shares some of the other members' inhumanness like her very low body temperature).

* The Winchesters in Supernatural. Hunting, making deals...

* A possible explanation for {{Michael Jackson}}'s extensive plastic surgery, is because he didn't want to look like his abusive father.
* The Durrell family, if youngest son Gerald is to be believed, were all amiably eccentric, with a few downright barmy older relatives. See ''{{My Family And Other Animals}}''.

* Caulder/Stolos's "children" in ''{{Advance Wars}}: Days of Ruin/Dark Conflict''. Cyrus is fairly levelheaded, but Penny/Lili and Tabitha/Larissa... notsomuch.

* Loz, Yazoo, and Kadaj from ''FinalFantasyVII: [[TheMovie Advent Children]]''.

* QED: Touma's family are in general CloudCuckooLander and are geniuses in one field or another.

* [[AceAttorney The. Von. Karma. Family.]]

* Subverted in the DoctorWhoExpandedUniverse 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.

* Arguably, The Weasleys from ''HarryPotter'' are one big kooky family. There's only one Squib, who Ron reveals to be an accountant.

**** Sirius was screwed up from the beginning, considering that he was attempting muder at the age of 15. And we don't actually get to know Andromeda and Tonks all that well, but they do seem fairly normal, if only a bit unusual.
