- The kid and the new person get along quite well from the start. If Status Quo Is God this person may not stick around for longer than the episode, usually due to a breakup. In this case the kid may be quite upset to see this happen.
- The kid is nervous about the person at first (sometimes due to already knowing them or still being sore about their missing parent), but gradually warms up to them. This may go either way in terms of the people staying together. In this situation the kid is generally shown as being irrational and in the way of their parent's happiness, which may result in An Aesop in which the kid learns to not be so self centered and understand the principle of Parents as People.
- The kid doesn't like the person at all and never gets used to them. This can become a recurring plot element, and likely to have the line "You're Not My Father!" (or Mother) spoken at least once. For extra angst, the new spouse might be the reason the first marriage broke up due to infidelity, which puts extra strain on the chances of the two coming to an understanding. If the person is obviously a villain, this can become Guess Who I'm Marrying?, with the kid often being the Only Sane Man who can see the evilness of the new paramour. But even then, sometimes the kid puts this aside to let their parent be happy.

- This is a source of conflict for Kaoru in Amagami when her single mother starts dating again.
- In the Anime/Manga Midori Days, Seiji helps his neighbor Shiori to accept her new mother after Shiori's initial dislike.
- Conversed in Lucky Star when Sojiro has a discussion with his daughter Konata about him possibly getting remarried. Sojiro anticipates that Konata would be against it because her mother Kanata would always be her mother, but to his confusion and embarrasment Konata apparently defies the drama by saying she'd be totally cool with it and even asks when she'd get to meet her new mom.
- Odd variation in Marmalade Boy. Miki's parents Jin and Rumi get divorced amiably, so do Yuu's parents Youji and Chiyako... and then they swap couples and the two "new" families move into a Big Fancy House to avoid parental issues. It takes Miki more than a while to accept it, though: despite liking her step-parents very much, she can't get used to the rest of the deal, unlike her nonchalant new stepbrother Yuu. It turns out that Yuu himself was just as distressed as Miki, and for the same reasons. He just hid it much better, and in fact he confesses that he envied Miki for being able to voice her disagreement while he couldn't bring himself to do so.
- While Chief Togakushi of Region seems oblivious to the feelings of his coworker Asagiri, his daughter Kanon is quick to notice the way she acts around him. This drives a wedge between the father and daughter, as she feels that it's too soon for him to abandon the memory of her mother.
- Oniisama e...
- A good part of Nanako Misonoo's early angst is related to how her mother married her stepdad when she was five. Not because said stepdad is a bad person, far from it (plus she' a total step-daddy's girl), but because her new classmates use it as an excuse for bullying her.
- Mariko Shinobu's father mixed it with Your Cheating Heart, as he first cheated on Mariko's mom with an actress and then ran away with her, pretty much abandoning Mariko and her mom. Her classmates, and specially Aya Misaki, also use this to bully her; in fact, in the anime one of Aya's earliest Kick the Dog moments come from first trying to shame Nanako over her family, and when Mariko jumps in defense of her new friend, she reveals Mariko's family situation to the whole school... No wonder Mariko snaps badly on her. It's even WORSE when the Shinobus DO get divorced (very publically), Aya again gloats about it... and Mariko cracks so violently that she attacks her with a boxcutter.
- Satoshi Oginome from Mawaru-Penguindrum. He hasn't even told his teenage daughter Ringo that he not only has married again, but that he's got a little daughter named Aoi.

Ironically, said Hospital Hottie had a son named Kazuma... and he and Tsubasa would later get hitched.
- This takes over the plot by the end of Sakende Yaruze! and all reactions are covered. Initially Nakaya and Tenryuu get along (1), but Nakaya is also nervous about older men in general (2), and when he finds out that Tenryuu wants a relationship with his father he is very averse to the idea and starts to dislike him (3). Nakaya moves out once they get together, and it's suggested that while he gets used to Tenryuu in the end he's never entirely happy with his father's choice in a partner.
- In Tenchi Muyo! Tenchi's mother Kiyone died when he was young, and even though he's an adult by the time his father Nobuyuki gets around to marrying Rhea, who's known them since she was in high school and was Nobuyuki's assistant in his architecture office, she's effectively already been his mother for years. Their relationship is good enough that Tenchi eventually realizes that many of his memories of his mother are actually composites of Kiyone and Rhea, since Kiyone's personality was actually quite different from what he remembered. As such, Tenchi is more than happy to see them finally get married, especially because it's what Kiyone would have wanted since she and Rhea were friends.
- In Ring Ni Kakero, Ryuuji and Kiku's mother marries a local man without telling her kids. The stepdad turns out to be alcoholic and a Domestic Abuser, so the kids end up running away to Tokyo so they can build their lives there and then bring their mom with them.

Later, Miaka finds out that Mrs. Yuuki read her diary, and misinterpreted writings about Tamahome as evidence that Miaka was dating and skipping Cram School classes. Miaka denies this, and also calls her mom out for dating someone yet saying she can't even think about boys. This gets Miaka slapped in the face, and she ends up running away, thus setting the story into motion.
- This is implied to be one of the reasons why Asuka didn't live with her father in Neon Genesis Evangelion. We see her talking on the phone to her stepmother in German (in a conversation full of Bilingual Bonuses in the English dub) and acts friendly enough, but as soon as the call's over she drops the act and it's clear that, while she doesn't necessarily loathe the lady, she doesn't like her either and doesn't want to even think of her as a replacement for her biological mother, Kyouko. Made worse by the implication that Asuka's stepmother was both the doctor that treated Asuka's maddened Missing Mom while also being the 'other woman' in the Sohryus's decaying marriage. For even worse, there's a further implication that Kyoko's suicide which in reality was an attempted Murder-Suicide where she hung the doll she believed was Asuka in her madness along with herself was at least in part to spite her husband.
- In Kyo Kara Maoh!, flashbacks show that Gwendal had a type 3 relationship with Conrad's human father Dan Hiri, partly due to personality conflicts (Conrad's dad was something of a Boisterous Bruiser, while Gwendal was The Stoic and a bit of a grouch even as a kid) and partly due to Fantastic Racism between Mazoku and humans. In the end, it's shown, Gwendal's hatred for him and desire to surpass him left a permanent mark on Gwendal's personality...and Dan Hiri considers having made such an impression on such a great man to be the legacy he spent his life searching for.
- In Howl's Moving Castle, Sophie and her mother have a good relationship but Sophie never gets to see her mother's new husband.

Her daughter Reiko does not take it well.
- Magical Girl Raising Project has this come up multiple times as part of Kano Sazanami's/Ripple's backstory. An extended flashback shows two instances involving it, starting with an incident in elementary school where other kids make fun of her over her last name changing every other month or so (which ends with her punching them out after they suggest that her mother is a whore, and as such she must be one as well), and ending just before the story proper as she meets her mother's newest husband (which ends with her knocking him unconscious and running away to live on her own after he starts trying to molest her).
- The modern Batwoman, Katherine "Kate" Kane, lost her mother when she was 12 years old, and her father got remarried to a wealthy Gotham socialite, who awkwardly enough is also named Catherine. Kate is always very quick to point out that Catherine is her stepmother, but they seem to get along well enough (though the fact that Kate is gay is implied to be a wedge between them, and Kate does remark that she lives to see her stepmother offended when she dances with Maggie Sawyer at a charity ball).
- In W.I.T.C.H., Will is not happy about her mother Susan dating Dean Collins. Mostly because of the fact that Dean is Will's history teacher and she's Book Dumb. Aaaawkward. They are currently on friendly terms. It helps that Dean has since become the father of Will's half-brother.
- Barbara Gordon seems to have gotten along well enough with her father Jim's second wife Sarah Essen Gordon, but it's implied she always felt a bit distant from her.

In the last panel, a severely distraught Ash is writing down all the details in a letter to his father; Ash still clings to the hope that his long-lost, estranged father will someday come home.
- The Labyrinth fanfic, The Color of Vengeance begins with Sarah being wished away by her future step-son, who wants her out of the way so his parents will get back together.
- In Child of the Storm, Harry and Jane are, at first, rather awkward (because he's only about half her age), but civil.

- In Teach Me, Olaf's reaction that his mom is dating his teacher goes surprisingly well all things considered (way #1).

She doesn't seem bothered by her father dating the new employee Shelley, and she gets along quite well with her future stepmother — who does prove quite helpful when Vada unexpectedly gets her first period. Apparently, no one had told her about such things yet, so Shelley steps in to explain and comfort.
- The sequel's showing of their relationship is beautiful, since Shelley and Vada are close without Shelley trying to replace Vada's mother. Shelley steps in to talk to Vada's dad when she worries that Vada is going to feel neglected due to the new baby and reminds him to spend time with her, talks frankly to Vada about the changes in her body due to her pregnancy, is genuinely interested in Vada's life and in knowing about her dead mother. She is the one who encourages Vada to learn about her mom and go on a trip across the country to try and find out more about her. Their relationship is a wonderful example of somebdy being a parent without trying to replace a missing parent.

- Anne Fine's Goggle-Eyes has the Tall, Dark, and Snarky Kitty Killin reminiscing about her antagonistic relationship with her mother's new boyfriend to a classmate with the same problem.

Eventually, Kitty accepts him... right before her mother breaks it off.

- In later books of Percy Jackson and the Olympians, Percy's mother Sally begins dating Paul after her husband Gabe "mysteriously" disappears.

- In The Changeover, right before Laura's little brother Jacko is attacked, their mother brings home her new paramour much to Laura's displeasure.
- In Hamlet, this is one of the titular character's main sources of angst. Of course it doesn't help that the new paramour is his uncle. And technically usurped his right to the throne.

- The Last Dragon Chronicles: Lucy takes to Arthur with a Type 3 rating.
- Vorkosigan Saga
- A Civil Campaign: While Ivan Vorpatril is well in his thirties when his mother finally decides to hook up again, he doesn't take it well:
Miles: You don't need to bellow.
Ivan: I'm not bellowing, I'm being firm!
Miles: Could you please be firm at a lower volume?
Ivan: No. Simon Illyan is sleeping with my mother, and it's your fault!
- Gentleman Jole and the Red Queen: On the other hand, Miles himself takes Cordelia hooking up with admiral Jole after Aral's death much better, but then, as it turns out, Oliver Jole always was a third leg in their relationship, which he probably knew (or at least suspected) all along, so he had had time to get used to it.
- A Civil Campaign: While Ivan Vorpatril is well in his thirties when his mother finally decides to hook up again, he doesn't take it well:
- In Persona 3, Yukari Takeba is disgusted with her mother's constant search for new lovers because she thinks it dishonors the memory of her dead father. As the link progresses, Yukari learns that her mother wants to remarry, but ultimately decides to wait until Yukari is ready.
- Persona 4 has Eri Minami, the Temperance social link, who recently married a single father and is trying to become close to her new stepson, Yuuta, but doesn't have any success.

- In Fire Emblem Fates, Hinoka was the slowest of her siblings to warm up to her stepmother, Mikoto, after her birth mother Ikona died and her father Sumeragi married Mikoto, who was likely a concubine prior to becoming his legal wife. Initially, Hinoka was very cruel and defiant towards Mikoto, though over the years she warmed up to her and regrets her actions by the present time of the story.
- Higurashi: When They Cry :
- There is an interesting example: Tsumihoroboshi-hen has Rina, the new girlfriend of Rena's father. It turns out that she's the lover of Satoko's Evil Uncle Teppei and plans to extort money from Rena's father,and when Rena finds out, Rina tries to kill her. Rena ends up killing her in self-defense. Then she kills Teppei. Things go downhill from there. Of course, Rena has issues with Rina even before all of the stuff above. It mostly had to do with the fact that Rena's mom cheated on her dad. She liked her mom's boyfriend before her mother told her that she was pregnant and intended to divorce her father to marry the boyfriend.
- A more traditional version happened in Satoko's backstory. After Satoko's mom remarried after going through about three other husbands, Satoko was not happy about her new stepfather and constantly fought with him, to the point where she faked child abuse from him in an attempt to get rid of him through social services. It didn't work. This comes back to bite her in the ass in some arcs where she is abused by Teppei, to the point where social services are reluctant to act out of belief she may be lying again.
- The sister-series to Higurashi, Umineko: When They Cry follows this up with an inversion. Battler likes his step-mother, Kyrie, viewing her as a sort of Cool Big Sis. It's his father Rudolf he holds a grudge against for remarrying so soon after the death of Battler's mother Asumu. In response, he went to live with his maternal grandparents for the six years leading up to the beginning of the story. And to make things more complicated? There was a child switch involved, and Asumu is not Battler's bio mom. Kyrie is his biological mother.
- The plot of Our Two Bedroom Story is kicked off when the protagonist's mother, single since the death of her husband when the protagonist was a child, decides to remarry. The protagonist is a bit uncomfortable with the idea, but the guy seems kind and genuinely in love with her mother, so she tries to be supportive, and decides to find somewhere else to live so that the newlyweds can have some privacy after their wedding.
- The early days of Better Days often had this as a plot element with Fisk's widowed mother Sheila trying to find someone new, including once dating her kid's principal (this ended badly, with him being psychotic and raping Sheila only to die under suspicious circumstances) and their married next-door neighbor Sam (who was also the father of Fisk's best friend, just to complicate things), who after having an affair with Sheila and being caught eventually married her years later. Fisk then had a a conversation with his mother where he told her that while it was too late for Sam to replace his father, it didn't matter, she was happy now, and that was what mattered.
- In Kevin & Kell, Lindesfarne (Kevin's daughter) bonds rather quickly with new stepmother Kell, while Rudy (Kell's son) has more trouble accepting stepfather Kevin, but does eventually. Species issues are probably relevant - Rudy, being a canine (fox/wolf cross), has some trouble accepting a rabbit as outranking him. Lindesfarne, on the other paw, does not have the pack structure issue complicating her relationship with Kell.
- In Roommates for added awkward two of the main cast members' parents began flirting / going out, namely James' mother with Jareth's father. Adds to the horror that this is a Mindgame Ship (The Gadfly / Magnificent Bastard), and that the family of Jareth is notoriously bad news. In the Spin-Off Girls Next Door Jareth is blessed with this trope on his mother's side too but that is more of a Guess Who I'm Marrying? situation as she got together with his rival.
- One episode of The Weekenders concerned Tino's reaction to his mother dating — first trying to sabotage it, then finding out he actually likes the guy. In a later episode his divorced dad comes by for dinner and the two of them comment on how awkward it is for him to have dinner with his ex-wife's boyfriend.

- The Simpsons:
- Comic Book Guy and Agnes Skinner dated for a time, made all the more awkward by the fact that CBG was younger than Seymour Skinner. It didn't appear to last past that episode.
- Similarly, Luann Van Houten dated several men before getting back together with her ex-husband Kirk, and Milhouse generally liked all of the men she brought home (one was an American Gladiator). It seems Kirk had much less luck with the women he dated, and the only one we actually saw ended up stealing his car.
- Edna Krabappel seems to be getting along well with her new stepsons Rod and Todd Flanders and intervenes with genuine concern when she believes that Ned's insistence on a Christian curriculum for the boys is actually doing them harm. The only problem is that Edna doesn't feel comfortable with the boys calling her "new mom", while they don't feel comfortable with calling her "Edna" (which is what Edna would prefer, but Rod and Todd have been raised to think it's rude to call adults by their first name).
- The Powerpuff Girls:
- The Professor's new paramour eventually turns out to be the villain Sedusa, but the girls were very suspicious of her from the start.
- One episode had Utonium date the girls' kindergarten teacher, Ms. Keane. The two together are a Fan-Preferred Couple but in the series the Powerpuff Girls hate the two together for being annoying. Eventually they breakup due to a disagreement about cats.
- An episode of Duckman featured this trope; Duckman brings his new girlfriend home to meet his family, wondering if they'll accept her. His teenage son Ajax cries "Mommy!", leaps into the woman's lap and starts sucking his thumb.
- Metalocalypse plays with this trope in the episode "FatherKlok", where Skwisgaar's search for his own biological father is interrupted by his mother introducing his new stepfather to him. Complete with a "You amn'ts my f**kings dad!" from Skwisgaar. However, by the end of the episode, the two of them get along rather well. Too bad this is Metalocalypse we're talking about...
- Stan from American Dad! has a creepy relationship with his mom, because he remembers how heartbroken she was when his dad walked out on them and fears any actual romantic interest would do the same. It turns out he's gone as far as kidnapping each of them, but comes around after Francine stops him from ruining her Third Date Marriage.
- Family Guy had an episode where Peter's mother started dating local reporter Tom Tucker. Initially Peter is upset and tries to patch things up between his mother and father, but after a little while he warms up to Tucker and they get along very well - only for things to get complicated when Peter's mother dumps him.
- Darkwing Duck's Happily Adopted daughter, Gosalyn, really likes his reformed criminal girlfriend Morgana. There is even an episode where, after Darkwing and Morgana have a fight, she tries to patch up their relationship with a Love Potion. Hilarity Ensues.
- This was never a problem in Phineas and Ferb where Phineas and Candace get along well with Ferb's father and likewise Ferb with Candace and Phineas's mom.
- When Vergil's dad started dating again in Static Shock it turned out that Vergil already knew her-she was the cop he ran from when she tried to search his backpack (which contained his superhero costume). Awkward.
- In The Movie to Rocket Power, Raymundo meets Tito's cousin Noelani on a trip to Hawaii and quickly gets involved with her. Otto can't stand her because she hogs his dad's attention and dampens the fun on their extreme activities; and Reggie resents her because she feels like Noelani is replacing their late mother.
- Even a hint of Malory having a sexual relationship hits Archer's Berserk Button (and Malory is FAR from celibate) so this comes up a lot. It's especially amusing with Burt Reynolds since Archer is torn between his love of Reynolds and his somewhat creepy obsession with keeping his mom single.
- Happens again in "Fugue and Riffs" when when we find out the trauma that caused Archer's Laser-Guided Amnesia: his mom getting married.
- In the Disney episodes of Doug, Patti's father began dating the school English teacher, Ms. Krystal. Patti was not initially thrilled, partly because it interfered with the bond she had with her dad, and because she still missed her mother. She eventually warmed up to the idea, and Patti's father and Ms. Krystal got married in the series finale.
- Though we don't know much of Papa Smurf's past, his dating Flowerbell the woodnymph in The Smurfs episode "Papa's Wedding Day" does become a matter of contention with his little Smurfs, up until they discover that Flowerbell was just tricking Papa Smurf into marrying her so that her captor Lord Balthazar could capture Papa Smurf in exchange for her freedom.
- Clémentine features a Type 1, with Clementine getting along pretty well with her widowed father's Nice Girl of a girlfriend, the Circus Girl Éole. The only time she's mean to her, it's mostly because of stress (Clementine is an Ill Girl) and Clementine's Fairy Companion Hemera quickly sets her straight.
- An episode of Witch has Will's mom hitting it off with her new history teacher. Will has no issue with her mother dating however the fact its her teacher turns her off. Will ends up accidentally ruining their romance when she knocked out her teacher (because she thought he was a monster in disguise). This causes him not to drop off papers to Will's mom, which leads to them breaking up because Will's mom deems him unreliable.
- However, she finds out in season 2 that her mom and the teacher got back together without telling her. She calls her mom out on it, and, after a bit of a cooling off period, the three go out to dinner together in an effort to connect outside of the classroom/house.
- In Steven Universe Sour Cream's mother Vidalia ended up marrying the fisherman Yellowtail some time after Sour Cream was born from a brief fling Vidalia had with Marty that left her pregnant. Yellowtail seems to get along with Sour Cream and not treat him any different from his biological son, Onion, but the two disagree over Sour Cream's dream to be a DJ when Yellowtail wants him to be a fisherman like him, and Sour Cream calls him by name or "my stepdad". Once Sour Cream sees Marty's true colors in the episode "Drop Beat Dad" he switches to "Yellowdad" and the two seem to be on better terms.
- In Over the Garden Wall, a big strain on Wirt and Greg's relationship is the fact that they're only half-brothers, as Wirt's mother remarried for unspecified reasons and later had Greg with her new husband. Wirt refers to him as Greg's "stupid dad" and evidently does not like him, with this disdain extending to Greg, not helped by Greg being a full ten years younger.
- The fourth season of The Venture Bros. plays this trope thoroughly, which seems odd given that the brothers only ever had one parent, and that didn't change. What changed is that longtime bodyguard Brock—who had already been set up as something of a Parental Substitute—quit the job, and former archenemy Sgt. Hatred stepped in. Hank in particular spends most of the season sulking, hoping for Brock's return, and baiting Hatred. He even tells him, "You're not my real bodyguard." Hatred, in turn, tries desperately to win the boys' approval, going so far as to force Hank to shoot him so that Hank will remember the day he "took a bullet for them". Later it turns out that Brock is still around, kind of, so when he and Hatred are together they tend to behave like ex-husband/new husband, especially where the boys are concerned.
