Shared Family Quirks in Anime and Manga.
- The 100 Girlfriends Who Really, Really, Really, Really, Really Love You:
- Mother and daughter Hahari and Hakari Hanazono can frequently be seen behaving or responding to certain situations in similar fashions. Sometimes it's subtle, such as both having a tendency to chew a fingernail when concentrating on work. Other times it's used for humor in having the two of them react in exactly the same way, such as both of them immediately deciding to peek on Rentarou when they know he's in the bath. In chapter 85, Hakari opens her shoe locker to discover Rentarou has provided her with the same kind of sexy glamour shots that she gives him, leaving her gibbering and calling the photos priceless. The next scene has Hahari being given similar photos, tailored more to her own tastes, leaving her gibbering and calling the photos priceless.
- Every member of Karane's family, down to her baby nephew, is a tsundere.
- All three generations of Yakuzen women have a Playful Cat Smile as their default expression, and grandmother and granddaughter Yaku and Kusuri both share a propensity for giving their drugs Exactly What It Says on the Tin names (whether Kusuri's parents share this is unknown).
- Kishika and her mother have similar deeply held desires they keep to themselves, indulging in them in secret: Kishika wants to be pampered, but is too proud to admit it, while her mother wants to pamper her, but respects her maturity.
- Gyaru Girl Ahko and her parents all talk in Valleyspeak.
- Matsuri and her paternal grandparents all swear like it's second nature.
- Asteroid in Love: Mira's mother Yuuko spams LINE stickers just like Mira does, leading both Ao and her mother to say "Like mother, like daughter" after seeing the latter's message.
- Ayakashi Triangle: Matsuri and his mother Matoi both wear chokers, keep their shirts open (the latter to the point of Navel-Deep Neckline), and frequently put their wrists to their hips.
- Bleach: Siblings Byakuya and Rukia Kuchiki have the same drawing skills and artistic perspective; their drawings are awful but they both think their artwork is superb. Part of the joke is that they're siblings by adoption but share the kind of traits you'd expect in blood relatives.
- Buso Renkin:
- As well as their intelligence and alchemical skill, both Papillon and his great-grandfather Dr Butterfly share the same flamboyant fashion sense and an obsession with butterflies.
- A number of characters at the beginning of the series note that Mahiro is essentially a female version of her older brother Kazuki, with the same hyperactive personality and taste in food. It is even implied that Mahiro shares an interest in Kazuki's Love Interest Tokiko.
- In Dragon Ball Z, both of Goku's sons share his love for food, nature, helping others, and pure heart. Gohan is more mature and serious while Goten is like Goku as a child except with some social skills. They all also have powerful tempers that flare up when their loved ones are in danger.
- The Elusive Samurai: Tokiyuki has a lot in common with his uncle Yasuie, in that he has a knack for getting out of trouble. Whereas Yasuie uses tricks and cunning to somehow survive the scrapes he gets into, Tokiyuki can simply outrun the trouble and fade into the background when he wants to.
- Fullmetal Alchemist: The main protagonist of the series, Edward Elric, seems to be absolutely nothing like his stoic father, Hohenheim. However, flashback chapters reveal they do share one thing — both react poorly to implying their are lacking in a certain physical (and non-sexual) characteristic. Ed absolutely loses it if he is called short, while Hohenheim gets defensive if someone calls him dumb.
- Though adopted rather than related by blood, Sōsuke of Full Metal Panic! speech patterns and bearing resemble those of his foster father, Kalinin, closely enough for Kaname to immediately to pick up on the similarities despite knowing very little of Sōsuke and Kalinin's relation. This is partly why Sōsuke's military mannerisms are so formal despite fighting only in less structured mercenary and guerilla units — while he has never been part of an organized state military, Kalinin was in the Spetsnaz.
- In The Hating Girl, both Asumi and her older sister have things sticking out of their heads that really shouldn't be there. For Asumi, it's an arrow that runs all the way through her head, the result of a childhood archery accident. For her sister, it's a fork stuck into the top of her head, which she did herself so that Asumi wouldn't feel completely alone with her condition.
- Kaguya-sama: Love Is War:
- Shirogane and his little sister Kei perform a Fist Pump in the exact same manner. In addition, both they and their father all enjoy drinking coffee.
- Kaguya and her cousin Maki have an uncanny amount of similarities for people with 8 degrees of separation, to the point that many people often comment on it. It's part of the reason why they don't get along very well. In fact, a lot of the panels in the latter's first Day in the Limelight were direct references to faces that Kaguya had previously made
◊.
- One case in The Kindaichi Case Files has a theater actress holding a spoon like she's holding a motorcycle handlebar. Later Kindaichi uses this knowledge to reveal said actress' sibling.
- The first chapter of the companion manga for Magical Girl Lyrical Nanoha Reflection reveals that Fate has picked up a few of Lindy's mannerisms in the six months since her adoption (most notably, they have an identical Quizzical Tilt).
- Love Live!
- Love Live! Sunshine!!:
- While they seem like complete opposites, Dia and Ruby Kurosawa have plenty of quirks in common. Both of them are passionate idol fans, especially of µ's. They also scream in the same "Pigya" when scared or shocked.
- The movie Over the Rainbow introduces both Mari Ohara's mother and You Watanabe's cousin Tsuki. The former shares her daughter's Cloudcuckoolander attitude and use of Gratuitous English, even arriving to the girls by helicopter just as Mari does in episode 3. The latter has a similar Character Catchphrase to You's "Yousoro" and a strong love for uniforms.
- Love Live! Nijigasaki High School Idol Club: Sisters Kanata and Haruka Konoe both love each other dearly, up to sacrificing their own well-being and desires for the sake of the other. Kanata works part-time and handles all the housework so that her younger sister can focus more on being a school idol, even when this is on top of studying for her scholarship and her own idol career. In episode 7, when Haruka suspects that her sister is overworking herself and finds out that she's been having trouble staying awake even at her school idol club, she decides to end her school idol career and take over housework duties from her sister so Kanata can finally rest. Not wanting her sister to sacrifice her happiness, Kanata considers dropping from her school's idol club until Yuu and the others talk her out of it, ultimatly helping Kanata and Haruka reconcile and Take a Third Option by both supporting each other as school idols and splitting housework between them.
- Love Live! Sunshine!!:
- In My Hero Academia:
- Shouto Todoroki really likes soba noodles and at one point when he sarcastically compliments his father on a scar he received in battle, he then slurps on them condescendingly. His brother Natsuo later does the same thing while Calling the Old Man Out, right down to the pose.
- Midoriya and his mother Inko are both prone to Inelegant Blubbering whenever they feel strong emotions, which is much of the time.
- Jirou Kyouka got her love of rock music and proficiency with musical instruments from her father and according to him, her sharp tongue is from her mother.
- Averted with Iida Tenya and his older brother Tensei, who lampshades the former's odd habit of making strange chopping motions with his hands. Iida is quite embarrassed to have this pointed out.
- In Naruto, the Ninja Families share their powers and inclinations for some reason. Naruto's mother Kushina was a female version of Naruto, especially in personality.
- A weird example in Neon Genesis Evangelion includes this not with a regular relative, but an Artificial Human and the person who donated the human portions of her DNA. Personality-wise, they are not very similar, with the donor being an ambitious, yet charming Well-Intentioned Extremist Mad Scientist who was raised in and heavily involved with a conspiracy, and the "clone" being a stoic, yet socially inept Sugar-and-Ice Personality Warrior Poet Child Soldier, but apparently, their way of wringing out their dust cloths is similar enough to freak out the donor's biological son. Interestingly, they do that similar thing in vastly different contexts — The mad scientist would have been so wealthy that she had no need to clean anything herself unless she enjoyed housewifely activities, while the clone was simply on cleaning duty at school, but isn't shown to be particularly cleanly in her home apartment. A straighter example would be a scene where Rei, the clone girl, is shown reading an advanced biology book, implying that she's inherited her donor's aptitude for it. Rei also has the "nurture" version of this going on, given that her stoic mannerisms, much of her body language and her tendency to fold her hands when seated are noticeably copied off the man who more or less raised her.
- One Piece: Even before Garp was revealed as Luffy's grandfather, they both showed a Bunny-Ears Lawyer mentality, being more concerned with eating most of the time and often being absent-minded. Ace was very much the same despite being adopted; his relative maturity is somewhat of a recent development and a result of being Luffy's primary caretaker, but even so, he shares many traits with his brother and grandfather, the most prominent being that he's a bottomless pit as well and prone to random fits of narcolepsy, even more so than they are.
- Ouran High School Host Club: Chika seems to be the polar opposite of his older brother. However, the manga reveals that Chika is actually emotional, fond of cute things, and has an animal motif like Hunny.
- In Ranma ½, when Ranma's mother Nodoka visits the dojo, Akane points out that female Ranma and Nodoka eat in the same manner when they're sat side-by-side. Genma and Ranma really don't want Nodoka to make the connection between "Ranko" and Ranma due to the promise they made her, and thus try to divert Nodoka's attention during the entire visit. Many times, before being told the truth, Nodoka points out how "Ranko" and Ranma act very similar, which causes loads of trouble for Ranma.
- The DiC dub of Sailor Moon has Serena try and give an excuse for her lack of concentration through Inelegant Blubbering. Ikuko merely responds "That's the same tired old excuse I used on my parents."
- The Forgers in SPY×FAMILY have them aplenty, which is impressive considering none of them are actually related by blood. In order:
- As much as Loid wants to be the Only Sane Man, all four of them are prone to wildly overblown Imagine Spots that operate on flimsy slippery slope fallacies. Almost every inconvenience has led to Loid thinking he'll be exposed as a spy, Yor thinking Loid will divorce her, or Anya thinking her parents will divorce and cruelly abandon her. Bond (the family dog) is thus far the most justified in this regard considering he can see the future, and one chapter outright confirms that he seriously, really would've died if he didn't do something about it.
- All three human Forgers are (in)famous for Megaton Punch scenes that are hilarious (Anya), horrifying (Loid) or both (Yor).
- A running gag for both Yor and Anya in the Japanese version is their tendency to incredulously shouting "Ga-n!!", which literally means "Clang!" or an onomatopoeia of "Shock!", whenever they are well, shocked. Loid officially adopts this family trait in Episode 16; an understandable reaction to being told that Yor is making dinner for the night. And if you listen closey, even Bond reacts with a "woofed" version of this shock ("Gwa~an!!") in the Anime version of Short Mission 3, after Anya shouts that she hates him for mauling her Penguin doll in a fit of jealousy.
- In the short-lived manga Takama-ga-hara, hero Yamato has a Childhood Friend, Mizuho, who's kind of obsessed with being a good match for him by getting stronger. In the penultimate chapter, we see that she has four sisters who are equally obsessed with Yamato's four brothers, each with the age-appropriate counterpart.
- Voltes V: Both Zambajil and Heinel love drinking the Boazanian equivalent of wine. He also inherited Kentaro/Gohl's drive for hard work, strategic genius and leadership qualities.
- Welcome to Demon School! Iruma-kun: Demonic families tend to share a great many quirks between them. Most of the Valac family are hyperactive, loud, and will burst into spontaneous choreography. The Andro family are thieves. The Azazel family have tall, red-headed people and a serious-intimidating aura. The Purson family are all shy and keep from the spotlight, but are also motormouthes when they get talking. Even people adopted into a family can have similar quirks to their new family, such as Sabnock' adoptive uncle Baal of the Thirteen Crowns being just as relentlessly and stubbornly determined about his beliefs and goals as both Sabnock and his father.
