Uncle Phil: Oh, I don't think so.
Will: Who cares what you think? YOU ARE NOT MY FATHER!
The closing line to any fight or disagreement between a child and either their parent or (more commonly) their important replacement parental figure (in the right genre, between the hero and their mentor).
This is either a loophole for someone who really is in the wrong and wants a reason to end the argument without defending themselves, or a way for a Good-aligned (or standards-bearing) offspring to inform their Evil-aligned parent [figure] that they have crossed the line and is no longer worthy of respect, admiration, or obedience. It can also be delivered to deliberately hurt a parental figure who genuinely feels that they are their parent in every sense but the biological. In this case, the accusation typically leads to guilt on both sides, and usually a last-minute apology and reconciliation...unless it turns out to be the last time they ever speak.
Much more rare, but not unheard of, is for someone to say this to their biological parent, oftentimes directly pointing how much better the Parental Substitute was at the job. Calling Parents by Their Name is a common way to express this variant. If this happens, it's possibly because the child just Hates Their Parent.
A twist that turns up the tension is "You're not his father."
Compare/contrast with I Have No Son!, to which the teen may fire back with this trope. Note that this trope is not generally related to I Am Not Your Father, since it's usually understood by both parties that the person really isn't their father (and that's the point).
- Bleach: Uryuu is so angry with his father Ryuuken's rejection of the family Quincy lineage that he verbally refuses to call him "Father", using Ryuuken's first name instead. Flashbacks reveal a past argument over it that culminated in Uryuu demanding to know why and being horrified when Ryuuken claims there's no money in the lifestyle. It's implied to be the moment when Uryuu lost all respect for his father, as it seems to be the last time Uryuu ever called him "Father" out loud. Ryuuken was actually lying to hide the truth but Uryuu hasn't yet realised.
- In Fairy Tail, Erza Scarlet finds out her birth mother is a despicable woman who gave birth to her just so she could take over her body and escape her own horribly cursed body, dumped her in a random village when she failed, and is now actively trying to kill her out of spite. Because of this, Erza understandably has no trouble telling her that her guild is her true family, not that said mother actually cares since they're enemies regardless. When her mother can't bring herself to kill Erza and takes her own life, however, Erza pays her respects by calling her "Mother" for the first and only time.
- Fruits Basket: Kyo shouted this (in a flashback) about his adoptive father, who became distant after overhearing it. It turns out it was because Kyo (who has self-esteem issues) didn't want people to reflect poorly on his adoptive father by thinking they were related, as he's not worthy of having such a good parent.
- Wrath from the 2003 version of Fullmetal Alchemist was created when Izumi tried to resurrect her stillborn son through alchemy. They met several years afterwards when Izumi and the Elrics discovered him living as a Wild Child on an island. Izumi treated Wrath like a son even before learning of his past and Wrath liked her back, but once Envy got his hands on Wrath, he returned his memories and Wrath went off the deep end. He rejected Izumi as his mother due to believing she abandoned him and ultimately began viewing Sloth as his Parental Substitute instead. Wrath didn't begin to acknowledge Izumi as his mom until shortly before her death. In Fullmetal Alchemist: The Conqueror of Shamballa, they end up Together in Death.
- In Hetalia: Axis Powers, The American Revolution is pretty much portrayed this way: America tells England, the Parental Substitute mixture of a father and a brother, that "I'm not your little brother anymore" during their final fight.
- High School D×D:
- Akeno Himejima is repulsed that her biological father, Baraqiel, wasn't able to save Shuri Himejima from being murdered by her own relatives.

By Volume 7, however, she reconciles with him thanks to Issei Hyoudou's help to the point that they defeat Loki.
- Vali Lucifer considers Azazel as his true father, as his grandfather Rizevim had Vali's biological father abuse him years before. Even when Vali's biological father died, that's as far as reconciliation goes.
- Used by Vivio on her adoptive mother Nanoha after Quattro manipulates her into fighting her adopted mother in Magical Girl Lyrical Nanoha StrikerS. This happened while Nanoha was being fueled by Mama Bear rage. Ouch. In an unusual variation, Vivio meant this literally. She'd been mind-screwed so thoroughly by Quattro that the poor girl genuinely believed that the person she was facing was someone disguised as her Mama in an attempt to deceive her. Even after she realizes that it's the actual Nanoha, she keeps this view since, as a clone made for the express purpose of moving a giant battleship, she doesn't view herself worthy of having parents.
- One Piece:
- Ace uses this phrase on Garp in a flashback, in response to him opposing his plan to become a pirate. Unlike some who invoke it on a non-biological father figure, he doesn't think much of his biological father, Gol D. Roger.
- In the Dressrosa arc, a minor flashback (a few days ago, rather than the usual year gap) shows a disagreement between sixteen-year old Rebecca and her parental figure, the Living Toy Thunder Soldier. The former wants to participate in a tournament so she could win the Flame-Flame Fruit and kill Doflamingo, the latter heavily protests against it, not wanting the young girl to die. His dissuasion, combined with her frustration following Doflamingo's fake resignation from the Seven Warlords of the Sea, leads to her saying that he's not her father, but just a one-legged toy soldier. Stricken and unwilling to argue any longer, the Soldier prays that she doesn't enter and leaves, as Rebecca, regretting what she did, tries in vain to get him to stay. Fortunately, they reconcile off-screen. It's even more hurtful for the Thunder Soldier because he is Rebecca's father. He is in fact the legendary warrior Kyros who was transformed into a toy. Nobody else, not even Rebecca, remembers him because people who are transformed into toys become unpersoned. Then, at the end of the arc she inverts it, tearfully begging him to stop pretending that he's not her father after he spread a rumor that she's the daughter of some foreign prince to spare her the shame of having a murderer for a father.
- Sanji understandably refuses to think of Vinsmoke Judge, the man who abused him as a child, as his father in any way. When Sanji meets Judge for the first time in years, the former reaffirms this during their battle. He also denies any relation to the Vinsmoke family as a whole since he makes it clear that Vinsmoke Sanji, the weak little boy they ridiculed, "died at sea" after escaping from Germa 13 years earlier. Even after rescuing Judge, Sanji still considers Zeff his true father.
- In Persona 4: The Animation, after Nanako finally has enough of her father putting his work before her, she subjects him to a tear-filled rant before finishing with this line and sprinting off upstairs. Earlier in the episode, she builds up to this by telling Yu that she doubts her father is actually her father because he seems to care about his work more than her.
- This is put to very emotionally moving use in Princess Tutu, when Rue finally defies the Raven.
- Space Pirate Mito is devastated when Aoi ends a fight by shouting "You're not my mom, you're just an alien in a suit that looks like my mom!" because she actually is his mother even if she is an alien in a suit. They reconcile when she tells him the story of how she met his father.
- In a routine done by Robin Williams, the Biblical Joseph, after hearing Mary is pregnant and he'd be "the stepfather of God's kid," feared he wouldn't be able to discipline Jesus since he'd just scream, "You're not my real dad!"
- Spider Jerusalem from Transmetropolitan was once told this by a person he was trying to interview.
- In Cloak & Dagger, when Tandy's stepfather says he wants to see her ballet recital because "isn't that what dads do?", she angrily says that he's her stepfather. She doesn't think much more highly of her biological father (who ran off to India after divorcing her mom), but at that point is stuck convinced that nobody cares about her. Looking back on it, Dagger thinks she was an idiot for blaming her stepfather for something like that and believes that he actually did love her.
Supergirl: No, listen to me. I have to say: I know you love me, and that's why you feel a need to act like my big brother or my dad — But you're neither one! I'm capable of recognizing my own mistakes, Kal! I don't need my nose rubbed in them! Maybe I'm not perfect like you —
- In Supergirl vol. #5 issue #22, Kara thinks her cousin is about to lecture her after her latest mess-up, and she interrupts him to remind him he isn't her father or her brother, she's trying to learn to be better, and she doesn't need his validation (Superman answers that he actually agrees with her).

- Issue 5 of the Transformers vs. G.I. Joe maxiseries has a flashback where a younger Duke refuses to accept his stepfather and his younger half-brother Falcon as family.
- In the climax of the first chapter of Pinocchio, Vampire Slayer, Pinocchio screams this at the vampirised Geppetto, as he tries to emotionally manipulate the wooden boy. Pinocchio's curse being such that he can't even lie to himself, his outburst immediately results in his nose growing and staking Geppetto through the heart, killing him (but also breaking the vampire curse, allowing Gepetto his own mind in his final moments).
- In Jonathan Joestar, The First Jojo after meeting his semi-true father Jonathan Joestar, Giorno burns the picture of Dio he stores in his wallet and replaces it with a photo of Jonathan.

Takuya Ikari: Shinji... I can understand your anger... but I hope you realize, that if you ever need me, as your Grandfather I will be here for you.
- Neon Genesis Evangelion: Genocide:
- During a talk with Rei, Shinji tells her that he doesn't think of Gendo as his father anymore.
- Rei does a more symbolic version by deciding, for reasons she cannot quite comprehend, to throw Gendo's old glasses in the garbage.

- The One I Love Is...: When Gendo is trying to force him to fight and kill the last Angel Shinji calls him out on all he has done to Asuka and Rei and screams he would be ashamed of calling himself "Ikari" if it was not his mother's surname.
- The Second Try: Variation. During his confrontation in the second-to-last chapter Shinji says he wishes Gendo was not his father so that he could hate him properly.
- Advice and Trust: Done indirectly by Asuka in chapter 9 when she revised her will and next of kin stuff, and she cut her father and her step-mother out of her will, declaring "Screw my father and that woman, Shinji gets everything". From that point on, she doesn't regard her parents as family.
- Once More with Feeling: Variant. After meeting his grandfather for first time, Shinji tells these words when he finally and intellectually accepts that his so-called blood relatives were never there for him.

- In Naruto:Asunder, Naruto directs this at both parents when they try (and fail) to explain sealing the Kyuubi in him and wanting to be a family again (unlike in canon, they're still alive). By the end of the story, however, not only did Naruto manage to make up with Minato and Kushina, but he also called them "mom" and "dad" just before the final battle against Madara.
"You BOTH aren't my parents. You don't deserve to be. I made it fine without you all these years and I'll keep making it WITHOUT YOU. Don't bother me ever again."

- Jen Potter/Black in Black Princess Ascendant does this via magical adoption (which replaces a single parent) to Lily. Narcissa and Andromeda explain that while she might prefer to do it to James, that would mean Lily was pregnant by two men at the same time and even magic insists they use something possible. As a result, as far as both magic and the law are concerned, Bellatrix Lestrange raped and obliviated James Potter during the previous war. Given that the Potters never filed any paperwork saying Jen existed, they can't prove otherwise.
- In The Prayer Warriors, Percy Jackson declares that Zeus is not his father (canonically, Poseidon is, but Zeus is in this fic) on two occasions - once when converting to Christianity and joining the Prayer Warriors, and again before killing Zeus, saying that so he can avoid committing the sin of patricide.

- In the Street Sharks fanfiction, Blades, this is basically Streex's reaction to Ripster calling him out on being unreliable.
You're not Dad John. You can't keep us all together like he can, and I'm sick of you ordering us around and expecting us to follow like good little soldiers. You don't have a clue what you're doing and don't even try to pretend otherwise. There's only one person who can undo what Paradigm does and he's not here.
- In Old West, Teddy Glossy says this when he first meets his no-good conman father Benjamin Hares, who abandoned his mother before Teddy was born and never showed up afterwards.

- Lyra in the Triptych Continuum legally divorced her Abusive Parents and now considers Bon-Bon to be the only family she has.
- The RWBY Loops has Weiss, after some consideration, decide to exclusively refer to Jacques Schnee by his first name as she feels no familial connection with him.

- Izuku manages to do this twice in Conversations with a Cryptid. His biological father is Hisashi Midoriya, but the man's never been there for him or his mother, and Izuku thinks of him as a glorified bank account. The second one is theoretical; when he notices that All for One referred to himself as being 'negiligent', which implied he owed Izuku a duty of care, Izuku promptly tells the supervillain that whatever obligation he has, he waives it as he doesn't want to be in debt to All for One or end up like Shigaraki. Which nails Hisashi right where it hurts.
- RWBY: Scars: Yang tells her biological mother Raven this. She had spent years looking for her, but was disappointed by how cruel and distant Raven was. Yang's deceased step-mother Summer was a better mother than Raven. Yang doesn't want Raven anywhere near her family and threatens to kill her if she does get too close.

Yang also approves when her son Yin (who was initially eager to meet Raven) calls her "bitch-grandma."
- In Purple Days, Joffrey never really stops loving Cersei, but her Stupid Evil and The Caligula tendencies grate on him across the "Groundhog Day" Loop he endures. In the Final Loop, he has a final conversation with her, and tires when she pathetically keeps trying to justify herself, so he turns around, leaves her and Jaime in a Gilded Cage in the Westerlands, and doesn't look back. To a lesser degree, he feels the same about Robert - while Joff comes to somewhat appreciate him, he ultimately feels Ned Stark did more to form him into an actual decent human being than Robert.
- Mako in Natural Selection cuts ties with her family due to their Acquired Situational Narcissism and their willingness to pimp her out to Ryuko just so they can keep up their lavish lifestyles.

Now if you'll excuse me..."Hans: "Your Majesty, if I may..."Elsa: "No, you may not. This is between me and my sister."Anna: "Ha! There's nothing between you and me, thanks to you! And you know what? I don't need your blessing! You're not my mother!"Elsa: "I may not be your mother, but I am your queen. And as your queen, I forbid it."

- Said by Kristy in the The Baby-Sitters Club movie, when her stepfather berates her for coming home late — from a secret visit with her biological Disappeared Dad, but he didn't know that. Made all the more heart-breaking by the fact that there are several points in the books where Watson plainly calls Kristy his daughter, even giving her an antique family heirloom in the Little Sister Spinoff, and her biological dad stood her up in the end, anyway. A little jarring though; this is never resolved in the movie (with Kristy apologizing to Watson for what she said), outside of her narration explaining to the audience she felt bad.
- A variation occurs in Terminator 2: Judgment Day with John Connor and his foster parents.
Todd: John, do as your mother tells you.
John: She's not my mother, Todd.

Loki: Did you mourn?

- She doesn't get to say it to his face until Avengers: Infinity War, but by Guardians of the Galaxy Gamora has disowned the Mad Titan as her adoptive father. She goes out of her way to emphasize this dissociation, explicitly mentioning to Drax that she's no family to Thanos (no-one has mentioned Thanos; Drax is trying to kill Gamora as an indirect method of getting revenge on Ronan), and sharply backtracks when she makes a Freudian Slip in a conversation with Quill.

In a deleted scene included in the Extended Edition, Miguel calls him out for being a drunk, and tells him that he's not their father, "just a man that married or mother," though Russell reminds him that Troy is his. As the movie progresses, Miguel sees how much Russell actually loves his children, and even feels proud when Major Mitchel tells Miguel "your father was a brave man," after Russell rams his fighter plane into the Invaders' ship's primary weapon, causing it to backfire and destroy the ship.

He later apologizes, seeing as how she HAS been a mother to him all his life, as his parents (her brother and sister-in-law) were killed in a train crash when he was a baby. However, as the reader knows, Sarah IS his mother—the entire story was a fabrication to prevent him or anyone else knowing that he was illegitimate.
- In To Sir, with Love, Braithwaite's students try to annoy him by constantly using obscenities when they speak. After one girl complains, "I can't do this sum, sir, it's too bleeding hard", he angrily asks her if she uses such words when speaking to her father. Her response? "You're not my bleeding father."
- In Amber Brown is On the Move, the title character shouts this after her new stepfather, Max, gets on her case about not packing the stuff in her room for their upcoming move to their new house. She's upset at herself, as she normally likes Max reasonably well, and it causes her to realize that she needs some help from her friends.
- After Bear and Lena elope in the Collegium Chronicles, Bear's father Healer Tyrall tries to kidnap Bear to force an end to the marriage. After he gets arrested for charging up to the Royal Palace (and home of the Healer's Collegium) with armed mercenaries, Bear publicly declares that he is no relation to Healer Tyrall. It's implied that this will have actual legal force.
- In Jane Eyre, after Jane's aunt unfairly punished Jane and locked her in a room that Jane was terrified of, the 10-year-old Jane vowed to never call her "Aunt" again. Since the aunt was Jane's legal guardian, this counts.
- In The Sandman and the War of Dreams, Book 4 of The Guardians of Childhood, Emily Jane shouts this to Typhan when he tells her "Daughter! Stop!" after she starts using her powers for harm. Pitch, the Big Bad of the series, is actually her father, but he's become like a surrogate father to her, so it stings badly.
- A variation occurs in the Septimus Heap series. Jenna tells this to Milo Banda after he makes a disastrous attempt at bonding with her and some of her brothers, and she runs off in a huff. The variation is that Milo Banda is her father... her biological father, but he's not the one who raised her. She's making the point that, while Milo may have brought her into the world, Silas Heap is her real father.
- Ana is The Glimpse after he rescues her from an Asylum.
- Star Wars Legends:
- One of the most severe insults you can throw at a Mandalorian is dar'buur. It translates directly to "no longer a father," but means in effect "unfit parent." Mandos take their family ties very seriously, with parenthood (particularly fatherhood) as a sacred tenet.
- Leia will not acknowledge her connection to Vader any more than she has to, in contrast with her much more forgiving twin, all but saying this trope to Anakin verbatim the one time he appeared to her as a force ghost. As far as she's concerned, biology is unimportant and Bail Organa deserves the honor, not the Sith that forced her to watch while the Empire blew up her adoptive parents with the rest of Alderaan. While she eventually makes peace with the fact that Anakin was not inherently evil, even naming her youngest son after him, she never stops thinking of Bail as her true father.
- After the Continuity Reboot, Star Wars: Bloodline shows that Leia is repulsed that she's the biological daughter of Darth Vader, the man who tortured her and committed countless atrocities, and refuses to think of him as her father in any way. While she does eventually realize that he was not inherently evil, that's as far as reconciliation goes and she still considers Bail Organa her true father.
- Warrior Cats:
"Leave us alone", he growled, "You're no mother to us, whatever you say."
- After learning that Bluestar is their birth mother, Mistyfoot and Stonefur initially act this way. They refuse to acknowledge her as their mother.
- Though not noted in the text, many unknowingly adopted cats, such as Cloudtail, stop viewing their adopted parent as a parent after learning the truth.
- Only Ashes Remain: Kovit tells Nita Henry's been like a father to him, he returns to the Family (the mafia organization to whom he's little more than a slave) because he starts to believe Henry actually cares about him like a son... but when Henry kidnaps Nita (with the intent of killing her for the bounty) and makes jokes about how you're supposed to introduce your girl to your parents, Kovit tells him, "You're not my parent."
- Wicked Good: When Wayne tells his adopted son Rory, "I'm your father. I know everything about you," Rory answers, "You're not my real dad." He has a point, as Wayne basically ignored him for two years after his parents' divorce.
- Said constantly by Arthur to his stepfather, Walter, in The Tick (2016). Walter doesn't seem to mind, as he recognizes that Arthur is still grieving over seeing his birth father be killed in front of him by the Terror.
- The lines are spoken word-for-word on several occasions when Claire Bennett tries to assert her independence from Noah, aka HRG guy. Naturally, her not-dad, despite his communication shortcomings, is usually right.
- It happened in a bigger way with Sylar. Angela went "Sylar, you're my son — oh no sorry false alarm." It was kind of pathetic.
- The Fresh Prince of Bel-Air:
- This happens in the landmark episode when Will's loser father shows up and invites his son to take a road trip. Will jumps at the opportunity, despite his uncle's warnings that his father can't be trusted—
Will: I've been waiting for this for a long time, my whole life, and nobody's gonna stop me now. Come tomorrow, I'm outta here.
Uncle Phil: Oh, I don't think so.
Will: Who cares what you think!? YOU ARE NOT MY FATHER!
- A more subtle version occurs at the end of the episode when his father abandons him again—
Lou: It was great seeing you, son.
Will: Yeah, you too...Lou.
- This happens in the landmark episode when Will's loser father shows up and invites his son to take a road trip. Will jumps at the opportunity, despite his uncle's warnings that his father can't be trusted—
- A variant of this appears in Power Rangers Operation Overdrive. When Mack, the red Overdrive Ranger discovers he is in fact an android built by the man he thought to be his father, he starts calling his father Mr. Hartford, instead of the more informal "Dad", as he did before. After the Grand Finale, the two reconcile, after which Mack starts calling him Dad once more.
- In the first episode of Once Upon a Time, Henry meets his birth mother Emma, who drives him back to Storybrooke where they are confronted by Regina, Henry's "evil" adoptive mother. This ensues:
Regina: Where have you been!? What happened?
Henry: I found my real mom!
- Sister, Sister:
- When Ray tells Tia that her new boyfriend just got out of prison and the bottom line is that she can't go out with him, she responds, "Well, bottom line, you're not my father!"
- Tamera says the reverse near the end of the series when Tia and Tamera meet someone who could very well be their biological father. Tamera gets pissed when he asks them to take a DNA test to confirm that he is their real father:
Tamera: I don't need a DNA test to know who my real father is. He's the man who's been there for me my entire life, and a good part of yours, too, Tia. His name is Ray Campbell, and as far as I'm concerned, he is all the father I will ever need.
- 7th Heaven, in the episode when Eric is trying to protect Robbie from his recently-resurfaced deadbeat father, Ed:
Ed: You're not his father.
Eric: Neither are you.
- Perhaps not quite average for the trope since the boy in question is a baby, not a teenager... But the line came up, unavoidably, in a very tense scene in the Lost episode "Fire & Water". Charlie, insistent on baptizing Claire's baby son regardless of Claire's wishes, runs afoul of Locke:
Charlie: Who the hell are you, John? Aaron's not your responsibility. ...You're not his father. You're not his family.
Locke: Neither are you, Charlie.
- A really bizarre example occurs in the UK science fiction comedy Hyperdrive. Technical Officer Jeffers is reminiscing about being raised by a computer simulation of his father, created when his father knew he was dying. Then, when Jeffers was fifteen, they got into an argument, and Jeffers said "You're not my real dad! You're just a piece of code!" and deleted the program. He tried to restore it the next day, but couldn't.
- The British Soap EastEnders had this sort of conversation, subverted because:
Zoe Slater: You can't tell me what to do, you ain't my mother!
Kat Slater: (Zoe's "sister") Yes I am!
- Six Feet Under - Claire uses this line plenty on older brother Nate.
- In Nip/Tuck, Matt says this to Christian right after the latter bails him out of jail. the twist is that Christian really is Matt's father and had only found this out in the same episode. Unusually for this trope, Matt's pronouncement is actually quite accurate- Christian isn't much of a father figure to him at all.
- A slightly depressing example occurs in the last episode of season one. Sam and Dean have managed to rescue their father and Dean is worrying about having wasted a bullet (it only has a few left and they need all the bullets they can get). Unknown to them, John has been possessed by the Big Bad ever since they found him. But when John comes out and tells Dean how proud of him he is, Dean realizes the truth and says exactly this.
- Played straight in a Season Five episode; a depressed Dean tells this to Bobby, who is trying to keep him from letting Michael take over his body. The same episode had Adam say this about John, who is his birth father, but didn't raise him.
- Season seven has a flashback of Bobby talking on the phone to John, who tells he is not Dean's father after Bobby decides to take him to the park instead of to practice shooting (Dean was just a kid at the time).
- There's an episode of CSI: Miami in which Horatio meets a teenage boy. Horatio keeps calling him 'son', until the boy snaps back at him 'You're Not My Father'... little does he know that Horatio had earlier run a paternity test...
- Angel: Angel's son Connor, raised by Angel's sworn enemy in a hell dimension, gets off at least one of these Eastwood style. He later identifies Angelus as his real father (who he wants to kill). In a later episode, his mother Darla's ghost appears to him and tries to stop him from murdering an innocent, but he rejects her too.
- Mystery Science Theater 3000::
- On Pod People, after singing "Clown in the Sky", Joel tells the bots that he loves them. Crow's reply is "You're not my real father!"
- A straighter (or well as straight as Mystery Science Theater 3000 plays anything) example is the Call-Back this gets in the revival. New human host Jonah introduces the bots as "his robot friends". Crow throws "you're not my real father, mister!" at him in response. Whereas Joel built the bots, Jonah is literally not their father.

- On Charmed, Paige delivered this line to her adopted parents during an argument on the day before they died, and spent years feeling guilty about it.

- Inverted in The Thorn Birds, as Paddy and Frank argue, Paddy tells Frank, "You're no better than the bastard who fathered you!", thus revealing what Frank has always suspected, that Paddy is not his father. Then in the midquel "The Missing Years", Meggie's Jerkass husband Luke returns to take custody of their son Dane. Meggie's mother Fee intervenes when Luke insists that he wants the chance to make up for being an absent and neglectful father, telling him "but you're not his father".

- The Flash (2014): In the second episode of Season 1, Barry and Joe have an argument about Barry's heroics on either continuing or stopping it. Joe arguments that Barry is jumping head first into playing hero risking his life, and Barry counters that the police isn't equipped to fight metahumans, leading to this exchange:
Joe: You think because you can run real fast that you're invincible?! You're not! You're just a kid. My kid.
Barry: I'm not your kid, Joe, and you're not my father. My father is sitting in Iron Heights, wrongfully convicted. You were wrong about him, and you're wrong about this. Now, I might not be able to help him, but if I can save someone from a burning building or stop some armed thieves, then I'm gonna do it, and you can't stop me. So don't try.
- At the end of the episode, however, Barry acknowledges that, while Joe might not be his father, he's still a dad.

Anne: [furious] Richard was right to shut you away. Now stay in here and be dead!
- A particularly powerful example appears in the All in the Family episode "Edith's Fiftieth Birthday." The first part of the episode sees Edith nearly being raped by a stranger; the second half details her resulting depression, shame, and PTSD. Her daughter Gloria, who was herself a victim of attempted rape earlier in the series, does her best to help Edith recover, but becomes increasingly frustrated by her mother's inability to confront or even talk about what happened. Things reach a boiling point when the rapist attacks another woman, and Edith refuses to identify him as the man in her own case, which would put him away for good. Gloria is shocked that her mother, normally a pinnacle of selflessness, is allowing this; her furious reaction causes Edith to slap her, then break down and finally realize that she needs to face her fears head on.
Gloria: You're gonna let him do what he did to you to God knows how many other women? I can't believe it! I'm ashamed of you! The mother I know would never refuse! My mother always helped other people! You know what? You are selfish! YOU'RE NOT MY MOTHER ANYMORE!

- In the Pearl Jam song "Daughter", the aloof speaker tells her mother, "Don't call me daughter." Theories abound.
- Played for Laughs in The Book of Mormon. In his quest to man up, the nerdy Elder Cunningham randomly yells this trope name at (an imagined) Darth Vader as means of asserting his place as the new protagonist. Could be Harsher in Hindsight considering his relationship with his real father.
- In Hamilton, Washington repeatedly calls Hamilton 'son' while admonishing him for the duel with Lee and trying to explain why he's not giving him an independent command. Each time, Hamilton interrupts "I'm not your son" until finally he roars "CALL ME 'SON' ONE MORE TIME—!". Even harsher with the historical fact that not only did Hamilton not have a father, but Washington never had any children. It is heavily implied that during the rest of the play Hamilton started to see Washington as his father the last time we see Washington alive is during the "the Reynolds Papers" number where Washington get the paper thrust into his face, and he answer with a silent look of disgust at Hamilton who until now stoicly stood still while people threw letters at him finally turned away his head in shame. And just before getting shot he glimpsed "the other Side" and he saw his dead Son, his dead Mother and Washington waiting on the Other Side-Washington taking the place of his actual father that he never knew.
- One of the main points of conflict in Harry Potter and the Cursed Child.

- Late in Disgaea: Hour of Darkness, Jennifer chews out her foster father General Carter, who only adopted her to use her for his plans. In the anime, she actually says "you're no father to me!"
- In Dragon Age II, most of the resentment Carver feels towards their elder sibling is because they were left as sole breadwinner and head of the household after their father's death, three years prior to the game. The Legacy DLC implies Carver found it extra hard to deal with, due to Hawke greatly taking after their father in personality.
- In Professor Layton and the Azran Legacy this is said more gently by Layton himself, after learning that Bronev, the Big Bad is his father. Layton considers the parents who raised him to be his real parents, but mentions being open to connecting with Bronev as colleagues, and possibly friends.
- In Jade Empire there's the possibility of this happening in two ways, depending on the character's Karma Meter. If you uncover the secret of Dawn Star being Master Li's daughter and have her with you for the final confrontation, she tries to appeal to him (either out of hope or to distraught him), only for him to be indifferent about their connection. She disowns him this way if she remains as an Open Palm character:
"I'm not sure what I expected my father to be, but I remember a time when I hoped he was someone like you. Not anymore."
"I always thought I had been abandoned. It was not until just now that I knew for certain. If I am dead to you, then you are dead to me."
- If she's been turned into a Closed Fist character, she uses this version:
- In Axel's ending of Twisted Metal II, he confronts his father, who cruelly attached him to his vehicle. After failing to reconcile, Axel just tears himself out, and fiercely delivers this line;
"I...am a free man. And you are no longer my father.
- Jacob Taylor's loyalty mission in Mass Effect 2 is to rescue his father, who went missing ten years ago. It turns out that his ship crashed on an unknown planet. However, after they find out that Ronald Taylor forced his crew to eat the local food (which causes brain damage) while keeping the good food from the ship for himself long after they repaired the beacon that justified withholding it in the first place, killed the other officers, exiled the male crew, and turned the females into his personal harem, Jacob disowns his father.
- And by "disown", what is meant is that one outcome, if the player chooses the right conversation options for Shepard, is that, when the camp is under attack by the surviving male crewmembers (who went feral), Jacob hands his father a pistol - with one round. Guess what he's expected to do with it. Then Shepard and the team leave, evacuating the female survivors.
- Even in the Paragon ending, Jacob denies that Ronald is his father any more, and the only thing preventing him from gunning him down right at that moment is that he doesn't believe Ronald is worth the effort of pulling the trigger.
- In World of Warcraft, during the Waycrest Manor dungeon, Lucille Waycrest gets angry when her mother, Lady Waycrest, calls her "daughter," angrily telling Lady Waycrest not to call her that and calling her a "witch" (quite literally, since Lady Waycrest resorted to dark magic to extend her husband's life).
- In Wolfenstein II: The New Colossus, the father of the protagonist B.J. Blazkowicz is...anything but a nice guy. B.J. doesn't fool himself, knowing firsthand exactly how much of a bad guy Rip was to him and everyone around him, but still manages to hold a little love for his father, if only for the sake of them being blood relations. However, what little love he had for his father died unceremoniously once Rip reveals he sold out BJ's mother (and his own wife) to the Nazis. BJ doesn't even flinch when Rip levels a shotgun at his forehead and only makes a single offhand comment about him being his son before dropping all pretenses and delivering a Pre Ass Kicking One Liner and killing the old man with no hesitation.
- Played very tragically in Umineko: When They Cry, where Ange's refusal to consider Eva as a mother, added to the latter's sadness and lingering hatred towards Ange's parents, made their relationship go to hell during the 12 years after the Rokkenjima incident. It doesn't help that Eva refused to tell the truth and was widely considered the culprit by gossips and tabloids.
- Homestar Runner uses it rather randomly at the end of one Teen Girls Squad episode.
- If the Emperor Had a Text-to-Speech Device has a special where Magnus invokes this against Tzeentch.

Tzeentch: WELL I'M THE BEST YOU GOT.
- In the Overly Sarcastic Productions summary of Paradise Lost, we see a hand-drawn frame of Satan storming away from God, yelling that he's not his real dad.

When Lindesfarne ends up babysitting Angelique's children from a previous marriage, she admits that she's unsure of what to call her, since Lindesfarne now considers her stepmother Kell to be her mother. Much later, Lindesfarne starts calling Angelique by name, thereby more or less officially disowning her.
- In El Goonish Shive Diane mentions to Susan that her biological father (who is well-versed into The Masquerade) is no dad to her:

- Avatar: The Last Airbender:
- Similarly in The Legend of Korra, Asami finally recognizes that the father she knew and loved is now gone, as he drew a line in the sand.
- Batman declares this once in the animated series. Being Batman (and, y'know, knowing that both of his parents died years ago), he's right. The hallucination of his father that was haunting him when Scarecrow gassed him once disappears and doesn't return again.
- BoJack Horseman presents BoJack as Sarah Lynn's chosen father figure, his status as her TV dad not making it very hard. When she reunites with him as an adult and he suggests she stay with him, she makes use of the opportunity to throw a days-long party in his house. When he tells her he thinks she needs to go to rehab, she rebuttals:
Sarah Lynn: You're not my dad! You're just a rugged older man who provided me with a strong masculine presence during my formative years!

- At the end of Samurai Jack, Ashi openly rejects her biological father, Aku, because he's a pure evil incarnate and was using her like a tool.

- Sari pulled this on her father in Transformers Animated after finding out that she was actually a robot, despite the combined efforts of Sumdac and the Autobots to reconcile them.

Horrified to learn they've been following the son of a mutant, they promptly abandon him whilst Graydon has a Villainous Breakdown, grabbing a nearby pistol and firing repeatedly at the Sabertooth hologram whilst screaming that Sabertooth isn't his father.
- In Drawn Together, Clara invokes this in an argument with her stepmother. Her stepmother then reminds her that her mother's dead, and after realizing that she went too far in bringing this up, the two reconcile and Clara's stepmother gives her advice on how to break her Octopussoir curse.
- Robot Chicken:
- The skit "Jedi Master George W./Jedi In Chief" more or less parodies this trope during a parody of the I Am Your Father scene in Star Wars, with George Bush as Vader and his daugther Jenna replacing Luke:
Bush: Jenna, get over here right now! I am your father!
Jenna: That's not true! That's impossible! My real father would let me go clubbing as late as I want! [flips off Bush]
- Another skit involved an aging Stretch Armstrong no longer able to stretch. He has surgery to restore his stretchiness, but is told to wait until his stitches heal. He doesn't listen, and he dies. His wife remarries Plastic Man, prompting her son to exclaim that he's not his real dad.

- Occasionally comes to a head in TaleSpin with the character Kit, a 12-year-old prodigy orphan the main character took under his wing after he'd been formerly apprenticed to one of the series' main villains. The laid-back Baloo and his somewhat professional-yet-motherly boss Rebecca often act as surrogate parents to Kit, who alternates between a child's need for adult guidance and his own fiercely independent streak, which usually works quite well unless Kit feels he is being disregarded because of his age. In the episode "Stormy Weather," the villain of the week quite ably leverages this insecurity against Baloo and Rebecca's protectiveness of Kit in order to convince the child the adults are "holding him back" from his true potential, leading Kit to eventually break things off with them on the grounds that "you can't tell me what to do! You're not my dad!"
- The Season One closeout for Scooby-Doo! Mystery Incorporated had Fred learn that the man he'd called father for years was actually some guy who stole him from his real parents as leverage against them; he was not ecstatic. It gets worse when he finds out his real father is no better, leading to Fred also disowning him too and choosing to forgive his kidnapper.
- In Star Wars: Clone Wars, while arguing with Obi-Wan, Anakin snaps at him that "You're no Qui-Gon Jinn!", referring to both Obi-Wan trying to live up to his late master's legacy as well as Qui-Gon being the closest thing Anakin had to a father. Anakin immediately apologizes and Obi-Wan forgives him.
- In Sym-Bionic Titan, Lance says this line to the King of Galaluna, who isn't a Parental Substitute, but was a friend of Lance's father. Immediately after saying that, Lance accepted that his father's dead, after the whole episode with optimism that he might still be alive since there was no body.
- After defeating him, Elyon says a variation of this to her evil older brother Phobos in W.I.T.C.H., having learned that he was planning to drain her of her powers all along.
Elyon: Goodbye, Phobos. You were never my brother.
- In Family Guy, Jesus says this to Joseph during a fight. He calls his real father, God, on the phone, asking Him to let Jesus move in with Him. God turns him down, because (unbeknownst to Jesus) He has a lady friend over at the time.
- In Super Best Friends Forever, Supergirl tells Superman this when the latter goes to enforce the former's grounding. Superman's response? "No, but I'm Superman and you'll do as I say!"
- In the pilot episode of Tom Goes to the Mayor, we see a brief snippet of one of Tom's home movies, where Tom's stepsons are throwing things at him while chanting "You're not our dad! You're not our dad!" It's Played for Laughs, or at least attempted anyway.
- In The Venture Bros., Hank says to Sgt. Hatred, "You're not my real bodyguard!" It drives home the fourth season's Parent with New Paramour theme resulting from Hatred replacing former bodyguard and Parental Substitute Brock.
- Heavily implied in Voltron: Legendary Defender, where Lotor would only refer to Haggar (eventually revealed to be Lotor's Altean mother, Honevra) as "Witch." Made explicit in Season 6, when Lotor tells Haggar that he considers Honevra dead and she was an abomination taking her place.
- Winx Club: In "A Great Secret Revealed", Bloom cries out to Vanessa, "You're not my mother!" when she realizes she was adopted.
- Doug: In "Patti's Dad Dilemma," Patti struggles with the fact that her widowed father is now dating her English teacher Ms. Kristal. After an awkward "family" dinner, she finally snaps, accusing Ms. Kristal of trying to steal her father and replace her Missing Mom, and telling her "You're not my mother and you never will be!" She regrets this afterwards and apologizes, though, and her father assures her that no one will ever take her place or her mother's in his heart.
- In the Rocko's Modern Life episode, "Who's For Dinner?", Heffer is dismayed when he finds out that he was adopted. George tries to calm Heffer down, telling him that he's still his father. Heffer tells George, "You're not my father! You're just some jerk in wolf's clothing!"
- In one episode of Sofia the First, Amber complains to Sofia about the way Miranda (Sofia's biological mother, Amber's stepmother) is being overprotective of them, complaining that Miranda isn't even her real mother. Sofia immediately (and sadly) points out that Miranda is as much Amber's real mother as Roland (Amber's biological father, Sofia's stepfather) is Sofia's real dad. While Amber never directly addresses this point with Miranda, she does eventually apologize for rebelling against her rules and recognize that she knows Miranda only has her best interests at heart.
- A serial killer was apparently able to kill about six women operating by this trope. Said women were drug addicts, prostitutes, women that their families just didn't care about anymore.
- Also invoked less seriously (or at least, seriously for a moment, then forgotten about) by much younger children when they're angry with their parents.
