Shared Family Quirks in Fan Works.
Crossovers
- In The Bridge, both Princess Celestia and Luna can have a habit of being a Deadpan Snarker, giving those close to them an Affectionate Nickname, and a love of sweets. On the kaiju side, despite not being related by blood due to the latter being adopted, Godzilla Senior's "sons" Xenilla and Godzilla Junior are both extremely observant, have Photographic Memory, and have a female best friend and right-hand kaiju.
- Child of the Storm:
- Harry looks more or less exactly like his father (or at least, like his father, Thor, did when he was James Potter), but he gets traits like his temper, compassion, skill at/inclination towards secret-keeping (along iwth a habit of enjoying it a little too much), and association with fire from his mother, Lily. At one point in the first book, Thor notes that Harry had unconsciously shifted into a pose identical to one his mother used to use — and that in both cases, it didn't bode well. He later gains more of Thor's personality traits, such as a taste for battle and a knack for command, on top of the love of/knack for flight and pure stubbornness that he already had. Likewise, he's also noted as looking a bit more like Lily as time goes on, particularly When He Smiles — which also makes him look startlingly like Jean Grey, his second cousin on his mother's side.
- Carol is tall, blond, blue-eyed, buxom, and a Badass Normal (later an Empowered Badass Normal) with an inclination towards using shields in battle, a talent for strategic thinking, insane stubbornness, an unflinching willingness to stand up to bullies, and despite her occasional grumpiness can always be relied upon to do the right thing. All of this foreshadows that her great-grandparents are Steve Rogers and Peggy Carter, much to the former's surprise.
- Wanda Maximoff, meanwhile, is sweet and kind, motherly to her godson Harry, a hero through and through. However, she also shares far too much of her father's cold ruthlessness and inclination to Pay Evil unto Evil in occasionally spectacularly horrifying ways for anyone's comfort — especially her own.
- Hermione, meanwhile, has chaos flavoured red magic, a taste for the colour red in general, an incipient talent as a Reality Warper, and an occasional tone of detached ruthlessness that Harry notes could have come straight from the mouth of her grandfather, Magneto. All in all, the reveal about her background (specifically, that she's Wanda's daughter) isn't that surprising.
- In Incorrect Smash Bros Quotes, an attraction to tsunderes runs in Dharkon's family. Dharkon himself is the most obvious example, being in a relationship with Galeem, but there's also Oz (whose girlfriend is Aaravi) and Soul Edge (who possessed Siegfried because he was a tsundere).
- Played for Drama and Dramatic Irony in Infinity Train: Blossoming Trail: While Goh's parents are concerned about his lacking social skills and tact, when they finally attempt to discuss matters with him, it goes very poorly. Mainly because they encourage him to focus on making new friends rather than trying to find Chloe, who's mysteriously vanished... unintentionally implying that she's easily replaceable. When Goh calls them out on this, his mother turns it back around on him in a way that parallels the argument that drove Chloe away in the first place.
- In Neither a Bird nor a Plane, it's Deku!, Izuku gets his penchant for snark, excited or distressed rambling and mumbling, and frequent crying from his adoptive parents Hisashi and Inko. His birth father, Jor-El, is no slouch in the rambling or snarking department either.
- In Can You Here Me (sic), Calvin has a son who is imaginative like him.
- In Frankie and Hobbes, Frankie (Calvin's daughter) is imaginative like her dad.
- In Hobbes and Bacon, Calvin has a daughter named Bacon, who has a similar idea of fun to her father.
- In Codes And Geass: Embracing Your Inner Megalomania, there is a particular expression that all members of the Britannian royal family share, in addition to various degrees of crazy. A certain devilish smirk marking just whose children they are. Of them all, Trollouche is the one whose expression most matches that of his father, Emperor Charles zi Britannia.
- Edward and Hohenheim in My Master Ed, both teenagers at this point, are short-tempered, argue constantly, and eat as if their food might run away from them.
- In Son of the Desert, it turns out that Edward's stubborn and determined nature comes from Trisha as shown in the Flashbacks of Trisha's courtship of Hohenheim. Both also share a preference for men older than them, something Pinako lampshades.
- Here Comes the Boogieman reveals that Egon's father was a scientist like him.
- Abraxas (Hrodvitnon): In this Godzilla: King of the Monsters (2019) fanfiction, Ren Serizawa has his differences from his late father (not as extreme as in Godzilla vs. Kong), but they still have a couple things in common. Dr. Brooks lampshades that he and his father both have a marine fascination, and Mark Russell notices Ren seems more like his forebears when observing what's about to become a Titan battleground.
- Harry Potter and the Magic of the Beasts: All Potter men share a trait where they succeed in every aspect of life but one. James failed at flirting, while Harry cannot tell female advances unless they are blatantly direct.
- In The Girls That Rocked the Loud House, Sam and Tabby, who are both punk rockers, are written as sisters.
- In Lincoln's Twin Brother, Lincoln and his Original Character twin brother Lio both read comics (although Lincoln reads all kinds of comics while Lio only reads manga). Also, Lio and his sister Luan both took up their hobbies to deal with loneliness.
- Lucy's Secret: The fanfic gives Hawk and Hank a brother, Huck, who is just as mean as them.
- Burning Bridges, Building Confidence: Marinette's cousin Cole turns out to be very creative, resourceful, and a natural planner who puts a lot of thought into things.
- Hero Chat: Chloé states that Adrien's "Just A Friend" quirk is common on his mom's side of the family, with Felix acting the same to Bridgette in a more Tsundere matter. She also suspects that Emilie might have been the same with Natalie if her Polyamory theory about the two and Gabriel is correct.
- Miraculous: Tales of Scarlet Beetle & Ikati Black: Lê Chiến Kim's mother, Khuyen, is just as athletic and a Competition Freak as her son.
- Scarlet Lady: As much as Audrey would like to claim otherwise, she shares a penchant for the dramatic statements as her two daughters.
- The Wolves in the Woods: After deducing Hawk Moth's Secret Identity, Mireya remarks on how much he shares in common with his son. Mainly that both vastly overestimate their own competence, arrogantly believing themselves to be untouchable — and consequently getting caught off guard whenever things don't go their way.
- Hold My Hand: A Mollibby Anthology has Libby's mother, Leah, act the same around her own female love interest as her daughter did with hero own, Molly. Molly finds it funny and cute, while Libby thinks it looks weird 'from the outside'.
- "Dear Diary, my assistant/nurse is going to be why I have a heart attack coming!": Izuku, Inko and Nana are all hopelessly Oblivious to Love. Recovery Girl curses Nana for having passed on that trait to her daughter and grandson.
- Inheritance reveals that Hisashi has the same habit of muttering quickly under his breath to himself as his son Izuku.
My Little Pony: Friendship Is Magic
- In The Great Alicorn Hunt, Fluttershy's parents and brother share her coat/mane colors, soft voice, and introverted demeanor. Like her, they are also surprisingly talented: her brother is skilled at martial arts, her father is a cloud sculptor/architect who developed the principles of cloud hydroponics, and her mother is a gardener in Cloudsdale. Yes, Fluttershy's mother grows plants on clouds.
- The Nuptialverse: According to Honeymoon, when Princess Cadance agreed to Shining Armor's marriage proposal, he reacted by jumping around shouting "Yes, yes, yes, yes, yes, yes!" This was precisely how his sister Twilight reacted to getting her cutie mark.
- Pound and Pumpkin Cake's Adventures (and Misadventures) in Potty Training:
- The first time she tries to use her potty, Pumpkin Cake forgets to take her diaper off. Mrs. Cake remembers that she too forgot to take her diaper off the first time.
- Pound Cake is reluctant to be potty trained during the story, and Mr. Cake says that he was the same way as a colt.
- Blackkat's Reverse: Kurama is an Uzumaki due to association and him possessing the late Naruto's body, but despite his denial, he shares Kushina and Naruto's Hot-Blooded and impulsive nature, Naruto's Chronic Hero Syndrome and Kushina's red hair.
- I Am NOT Going Through Puberty Again!: Naruto implies that the Uchiha must all share a nurse fetish after learning that some magazines Sasuke had him hide were actually Itachi's.
- Naru-Hina Chronicles:
- Similarly to her sister Hinata, Hanabi was initially shy and blushing a lot towards her oblivious crush (Konohamaru in this case).
- According to Kakashi, Kushina liked ramen and loved to play pranks, just like her son Naruto.
- One flashback set during Kushina's bachelorette party showed Hinata's mother doing some Shy Finger-Twiddling, just like her eldest daughter.
- True Potential: While having a conversation with Tayuya, Sasuke notices that she's doing "that stupid back-of-the-head rub that Naruto does" and sees that as a sign that they really are related.
- your move, instigator (draw your weapon and hold your tongue): Aburame Shikuro shares his nephew Shino's habit of making a statement, posing a question, then answering his own query.
- Comes up frequently in Time Fixers: Nicktoons of the Future with the Nicktoons' children.
- Like Danny, Darry fights ghosts and uses the same Battle Cry when transforming and is as much of a Snark Knight as he is. It is also pointed out that he is similar to his paternal grandfather in personality.
- Yuki loves to hunt ghosts like her father's side of the family and is a Deadpan Snarker like her mother and is jealous of her brother's ghost powers like her paternal aunt. She is also oblivious to her best friend's very obvious crush on her like her father was to his best friend's crush on him.
- Tammy obsesses over her crush on Jimmy much like her mother obsessed over her crush on her father. Both she and Tommy inherited their father's short attention span.
- Crash has his mother's southern dialect and need for action. He, Junior, and Buster all inherited SpongeBob's laugh.
- Max has his mother's fiery temper and uses his own version of his father's "Pukin' Pluto" catchphrase.
- Achilles' Heel: Lusamine and her son Gladion scowl in the same way.
- Frequently pops up in Pokémon Reset Bloodlines, with many characters strongly implied to be Ash's half-siblings sharing a few personality quirks:
- Iolani and Belladonna both use "Daycared" as a euphemism for a one-night stand.
- Velvet and Iolani have apparently independently of each other reached the conclusion that whoever their biological dad is, he deserves a good punch to the face.
- Ash and Velvet have similar reactions when their Pidgeotto and Alolan Meowth evolve during the final segment of a battle.
- Like Ash, Frax seems to have the habit of turning his hat around when it's time to get serious.
- Red and Ash, upon seeing an Alolan Exeggutor and being told this is their "real" form, internally decide they prefer the "false" ones.
- The Road You Choose uses several shared quirks as an indication that Ash and Dawn are half-siblings, such as similar expressions when bewildered and an excitable nature.
- In Severance, Ash and his mother Delia are more alike than meets the eye. They seem like opposites at first, with Ash being a Hot-Blooded and pro-active kid while Delia is mellow and prefers to stay home, but Ash actually gets his reckless and stubbornness from his mother. It's just that Delia rarely ever shows this aspect of her personality. Professor Oak remembers her being headstrong and impulsive when she was younger, but he had thought that Delia had changed with age.
- Family of the Shield runs on this with Naofumi Iwatanis' sons and daughters all having similar quirks and personality traits that are associated with him or with Raphtalia.
- Monti Iwatani is quiet and reserved, sharing his fathers' sense of self-doubt and mothers' sense of self-worth. Later on, Naofumi discovers that both of them love being petted on the head by him.
Blood be damned, these two are related.- Filo Iwatani is introspective and is able to read others emotions as a Living Lie Detector similar to how Raphtalias' able to tell when Naofumi is thinking of something rude or evil.
- Teal Iwatani is calculative and uses her intelligence to work through problems that the family faces, similar to how Naofumi often uses similar methods and misdirection. To her chagrin later, Teal laments that she also inherited Naofumis' own naming conventions whenever she creates new Bioplant-derived plants.
...Why'd I inherit Dad's naming abilities?- And lastly, Leon Iwatani is loud and bombastic, similar to how Naofumi presents himself as The Gadfly or using his way with words as a merchant peddling his wares. Leon's also shown to have a measure of dislike towards bullshit and authoritarian figures standing in his or his families way of getting stronger.
- In The Joys and Sorrows of Young Charles Finster, Drew is revealed to have been a Bratty Half-Pint in his childhood. In canon, when he grows up, he has a bratty daughter named Angelica.
- My Abominable Monster Classmates Can't Be This Cute!: Yang and Raven have a lot of character traits in common with each-other, even more so than their canon selves due to Yang's extra angst and harsh upbringing under Salem's thumb. Yang and Raven both value strength, and they run away from their fears rather than face them, as observed by Jaune in Chapter 39.
- Relic Of The Future: Jaune and his adoptive daughter Emerald are both extremely oblivious to other people's feelings and romantic overtures towards them. In Emerald's case, this at least partly due to being emotionally stunted by her time on the streets before Jaune took her in, whereas with Jaune, it's just the way he is and not even several years of fighting Salem in a Bad Future were able to change that. Jaune also observes to Emerald in Chapter 27 that they both have stubborn streaks.
- The Simpsons: Team L.A.S.H.: All four members of Team L.A.S.H. share a few quirks with at least one of their parents.
- Liv has Krusty's Signature Laugh and "Hey hey!" catchphrase, as well as similar problems with addiction (Krusty is a heavy smoker, and Liv gorges herself on salty snacks).
- Anastasia shares a lot of quirks with Mr. Burns: Antiquated Linguistics, a tendency towards Finger-Tenting and saying "Excellent...", answering the phone with "Ahoy-hoy?", a fondness for dogs and birds, and a generally haughty attitude.
- Simon, just like Principal Skinner, has a very stilted and precise way of speaking, is Obsessed with Perfect Attendance, and is way too attached to his parent(s) (Simon is a Clingy Child, and Seymour is a Momma's Boy). Heck, in "First Day of Cruel", he responds to one of Hikaru's questions with a Blunt "Yes" that is specifically described as "with the same inflection as Skinner when asked about the aurora borealis in his kitchen".
- Hikaru shares Comic Book Guy's love of, well, comic books, as well as geek culture more broadly. In addition, in "First Day of Cruel", he describes a week in which he was banned from using electronics as the "Worst. Week. Ever."
- In Sword Art Online Abridged's second season, we first meet Suguha rubbing in her physical superiority during a kendo sparring session, followed by her improvising a long and sarcastic story to mock her brother with... which is exactly what Kirito was doing to Klein at the start of Season 1, suggesting that he modeled his online persona upon his Little Sister Bully's behavior in real-life. And as Princess Leafa in Alfheim Online, Suguha starts a dramatic infodump with "For you see!", discusses throwing waves of disposable minions at a problem, and gets pissed when Kirito implies she's too weak or inexperienced to do something, all things we saw Kirito do in Aincrad.
- Total Drama Legacy, as a Spin-Offspring fic of Total Drama, has tons of these.
- Storm shares her father Lightning's "sha-" Verbal Tic.

- Wayne, just like his mother Lindsay, has a tendency to get people's names wrong.
- Marlin and Marissa both tend to call people "dude" or "brah", much like their father Geoff.
- In a more subtle example, Cody Jr. spends much of his time online and uses internet lingo in casual conversation, just like his mother Sierra. However, said lingo is updated; instead of early 2010s internet lingo like "LOL" and "OMG", Cody Jr. uses late 2010s-early 2020s internet lingo like "based" and "bruh moment".
- Carter has a tendency to sleepwalk naked, just like his father Owen.
- In Clémentine, Squirrelflight and Brambleclaw see a bit of each other in their adopted kits. Despite not being their biological father, the triplets do show some characteristics that they learned from their father.
- In An Astral Drop in Heatherfield, Will comes by her fiery temper naturally, which can make her relationship with her mother rather explosive.
