"How is it that the best parents always have the most dickass relatives?"Everyone has an uncle who they're not allowed to go camping with. For some reason, the brother and occasionally sister of the hero's father has a tendency to be evil. No-one is exactly sure why, given that the two were raised in the same environment and it can't be In the Blood. Maybe simply because of envy, and because the uncle will stand pretty high in the succession row. The concept stems far back to the medieval days, where the firstborn son is the crown prince, the secondborn son is the "replacement" if the firstborn happens to die, and the thirdborn... well, he's sent off to the church. Naturally, the secondborn won't grow to like his position, in turn making this trope a corrupted version of Middle Child Syndrome — though in most media, there's only two brothers in the first place, if only to avoid cluttering up the story. This has a tendency to escalate to Cain and Abel; in fact, it almost always does. If he is from a royal family, which he frequently is, he is most commonly The Evil Prince. In those cases, he is usually the younger brother, with no children at all, while his older brother usually has at least one. He will usually end up killing his brother, thus triggering the hero's quest for vengeance. He may try to kill the hero by giving him The Quest for an Impossible Task; this is usually unwise. A female equivalent is likely to be the Wicked Stepmother; she is unable to inherit herself, but her children can. When your mom and dad are the problem, see Evil Matriarch and Archnemesis Dad. Can overlap with Cool Uncle (see: Evil Is Cool), in this case, the uncle himself might be a Freudian Excuse for a character's Start of Darkness or Face-Heel Turn. He rarely is a Creepy Uncle, though, though some measure of overlap with that trope is possible depending on the uncle. Contrast with Evil Nephew. A common way to give a character a terrible childhood all in one go is to kill off their (invariably wonderful) parents and send them to live with their Evil Uncle (and/or their Evil Aunt) — the dark side of Nephewism.

Anime and Manga
- Richard Hellsing (has anyone noticed the symbolism?), the younger brother of Arthur Hellsing in the eponymous anime and manga, has had his own plans about what to do after his brother's death - specifically, about who inherited the family title and leadership of the Hellsing Organisation. Oh, Arthur willed it all to his twelve-year-old niece, but that just means Richard has to get little Integra out of the way. Unfortunately for him, he didn't account for a certain family heirloom...
- Kemono no Souja Erin has Damiyah, who is quite charming when he isn't coldly threatening.
- In Vinland Saga it's revealed that Thorkell, considered a lunatic Blood Knight by his fellow Vikings, is actually Thorfinn's great-uncle.
- The Sand siblings uncle Yashamaru, or so it seems. He was ordered to pretend to be evil.
- Neji viewed Hiashi, Hinata's father, as this for a good portion of his life. He eventually learns he's not as bad as he seems and he didn't force his twin brother to die in his place.
- Raditz, the first villain that appeared in Dragon Ball Z. When his brother Goku refuses to help him exterminate the natives of other planets, he kidnaps Gohan, intending to use him as leverage over Goku and/or raise him to be a villain himself. Being the Starter Villain, he doesn't get that far.
- In Tokyo Ghoul, Kanek's maternal aunt is this combined with a hefty dose of Evil Stepmother. She constantly went to her widowed, Extreme Doormat sister for money, requiring her to work extra jobs until she died from overwork. Kaneki went to live with his aunt's family, quickly discovering that they had been much better off to begin with and simply wanted more. Kaneki's aunt spent the rest of his years living with her neglecting his basic needs, leaving him out of family meals, berating him if he dared to speak in her presence, throwing out the books he inherited from his father out of spite, and generally doing everything in her power to grind every ounce of happiness out of him for the crime of existing. To top it all off, she also constantly complained about how terrible her sister had been. You know....the one that worked herself to death without complaint because her sister wanted a new fridge and a bigger television. And all because she resented her sister for supposedly being smarter/better than her while they were growing up.
- In a short-lived '80s reboot Shazam! The New Beginning, Billy "Captain Marvel" Batson's arch-nemesis Doctor Sivana was revealed to be his step-uncle. This was undone a few years later. Note that back in The Golden Age of Comic Books, Billy already had an Evil Uncle, Ebenezer Batson, who kicked him out on the streets after his parents died; Uncle Ebe was restored in the '90s Reboot that set the current canon.
- In X-Men: The Hidden Years, a series that chronicled early, apocryphal adventures of the original team of X-Men, Angel's uncle is revealed as an anti-mutant bigot who hates himself for not killing Angel when he was a child.
- Even originally, Angel's uncle Burt was a supervillain responsible for the deaths of both his parents on separate occasions.
- Scrooge McDuck, of all people (ducks), has occasionally bordered on this trope, especially in Italian comics. While not actively malicious — most of the time — he thinks nothing of exploiting and downright abusing his relatives, using various threats such as removing them from his will, evicting them from their homes or even heaps of physical violence in order to get them to work for him for one-tenth minimum wage. In addition, he uses any trick or excuse to avoid having to pay them at all, and interestingly enough he almost always gets away with it.
- Gar "Beast Boy" Logan was handed over to his uncle, Nicholas Galtry. Galtry was a vicious jerk who made it no secret that he was just after the money Gar's parents left for his care. The kid ran away and found Doom Patrol, and the Patrol had no problem telling the guy to pick on someone his own size and power level...
- Darkseid's uncle Steppenwolf is pretty evil and he wasn't too thrilled about Darkseid's rise to power (not out of ambition but simply because he didn't like the idea of anyone being able to take anything from him), but Darkseid is worse. Much, much worse.
- Jarvis Kord, uncle to the second Blue Beetle, and one of his more dangerous enemies.
- Tabitha's uncle in Points Of Familiarity keeps sending her on impossible missions to get her killed. She insists on not only surviving, but successfully completing them.
- This isn't an example specific to this fic. Tabitha's relationship with her uncle is canon.
- Some fanfics of Avatar: The Last Airbender suggest that Ozai might have had something to do with his nephew Lu Ten's death.
- An Axis Powers Hetalia fic, The Danish Slaughterhouse has Denmark plotting the murders of his family and raping his nephew, Sealand several times.'
Films — Animated
- Scar from The Lion King is probably one of the most famous examles, murdering his brother and afterwards attempting to murder his nephew in order to take the throne, all based on Hamlet.
- Hades from Disney's Hercules. The movie never mentions it, but Hades is technically Zeus' brother (Hell, most of the Greek gods are related), so he's Hercules' uncle and MAN, he's evil. He tries to usurp his brother Zeus, tries to kill Hercules lots of times, enslaves demons and mortals, and plans to rearrange the cosmos upon taking control of Olympus.
- The TV series frequently mentions that Zeus, Poseidon and Hades are brothers. For some reason though, the uncle/nephew relationship between Hercules and Hades is glossed over.
- Though it must be said, Hades was Hercules' uncle as well in the original myths, but it was Hera rather than Hades who was the main antagonist in the story.
- Ursula from The Little Mermaid is actually Triton's banished sister according to the original script notes, which changes their dynamic considerably and explains why Ursula is resentful of Triton's power. It also makes Ursula into Ariel's evil aunt.
Films — Live-Action
- Sir Edgar from Ella Enchanted is one of these to Prince Char. In grand Hamlet fashion, he murdered Char's father in order to become King.
- Uncle Charlie from the film Shadow of a Doubt is one of the first major examples of a psychopath in cinema and a very creepy and evil uncle.
- In Stardust, The Reveal is that the scheming and fratricidal Seven Princes of Stormhold were actually Tristan's uncles. They're not the primary villains, though. This is more obvious in The Film of the Book.

- In The Librarian 2, Flynn's Uncle Jerry is a lovely man who Flynn idolised growing up until The Reveal when he becomes a Smug Snake out for revenge and is revealed to have killed Flynn's father.
- Frank from Hellraiser. First, he has an affair with Kristy's stepmother, making Kristy's father's marriage an unhappy one. Later, he causes the horrible death of Kristy's father. Not to mention that it's shown that the novelty of doing it with the stepmother had worn off for him... and he's shown to take very well to the idea of turning his attentions to Kirsty. Numerous times, he's shown trying to rape her, including a scene where they kiss.
- Dastan's uncle in the Prince of Persia: The Sands of Time movie. His ultimate goal is to turn back time so that he can let his brother die as a teenager and reign in his stead.

- Bo Baker's Uncle Bill from High Stakes, an abusive asshole who gave Bo his job at his news station just so he could have someone to kick around when he wasn't popping pills or drinking.
- Uncle Silas is a 1947 Gothic Melodrama in which the eponymous uncle played by Derrick de Marney seeks to wrest Jean Simmons' inheritance from her. Released in the US in a butchered version called The Inheritance. Silas is this trope although more of the menace is provided by Katina Paxinou as the evil governess.
- Prince John is Philip of Cognac's evil uncle in Princess of Thieves, and plots to keep Philip from ascending the throne.
- In Legend Of The Black Scorpion, due to being an adaptation of Hamlet. Uncle kills father, takes power, tries to kill nephew.
- Uncle Les in Brain Dead is a repulsive sleazy Jerk Ass who tries to blackmail Lionel out of his mother's estate.
- Kevin's Uncle Frank in Home Alone treats him quite poorly, and shows no emotion when his parents leave him behind accidentally. In the sequel, he hasn't changed much, although he does mellow slightly by the end.
- Hades as portrayed in the actual myths is gloomy and dark, but happy with Erebus, and he never had any problem with Herakles borrowing Cerberus for a little while. But he did abduct his niece and force her to marry him. Sometimes this depends on the character interpretation.
- Older Than Dirt: Set, the Egyptian god of chaos, violence, and the desert, murdered his brother Osiris and usurped his kingdom. Then afterwards, Osiris's sister/wife Isis had to hide their infant son Horus from Set. When Horus gew up, Set refused to return the kingdom to Horus, leading to a long fight between them.
- In Hindu Lore, the Avatar Krishna's uncle Kamsa was a kind fellow who loved his sister until he heard a prophecy stating that his nephew would overthrow him. This made him go berserk, imprisoning his sister and killing her nine children in succession as soon as they were born. Needless to say, the tenth child escaped and kicked his ass after he grew up.
- Also in Hindu mythology is the uncle Shakuni from the Mahabharat, who right from the start hates that his sister marries a blind man(and subsequently blinds herself with a cloth as well) and forever plots for his nephew to be king, while plotting against his other nephews who have a better right to be king.
- Loki in the actual Norse Mythology, is not Odin's son as in the Marvel version but his foster-brother (a custom of the Norsemen where very close friends took an oath that made them legally siblings). Although mostly a trickster, in the end he is destined to murder his foster-nephew Baldr and start the process that will lead to Ragnarök!
- The founders of Rome, Romulus and Remus, killed their grand-uncle, Amulius. Who had usurped the throne of Alba Longa from his brother Numitor and killed his son and daughter (the mother of the twins).
- Phenomena has an interesting take on this where Tarkan is actually the Chosen Ones' adoptive father Sha-ra's younger brother Mentor, making him pretty much this. Interestingly does he take a Heel-Face Turn to help out when Sha-ra dies to make up for his sins.
- Inverted in Dragon Bones; Ward's father (who dies at the beginning of the novel) was abusive and an all-around jerk, while his uncle, Duraugh, is a quite decent person, who tries to convince himself that he doesn't want castle Hurog (which Ward is going to inherit). He does want it, but it's not his fault, everyone who grew up there is attached to the area, it's a place of magical power. In the end, he doesn't get in the way of Ward inheriting it.
- Uncle Vernon and Aunt Petunia from Harry Potter. Harry's bedroom for all but one of the first ten years of his life was the cupboard under the hall stairs. They were child abuse incarnate.
- Genderflipped in that instead of the father's brother and his wife, we have the mother's sister and her husband.
- Subverted in Tom's Midnight Garden, with the Kitsons. Tom is bored and miserable, at first, when he must stay with his aunt and uncle, and he wishes they were evil so he could be justified in running away. The same book features an Evil Aunt in Grace Melbourne, who terrorizes and emotionally abuses her niece, calling her a monster and a charity-child.
- Jane Eyre gives an interesting case of this. Jane's aunt is a Wicked Stepmother in all but name, but both of Jane's uncles in the book are portrayed as nice, charitable men, including the evil aunt's husband and another that left Jane an inheritance.
- In Sophia House by Michael D. O'Brien, Great-Uncle Nicholas is a pedophile, who molests his six-year-old great-nephew, the protagonist. Also, a Creepy Uncle.
- Miss Honey's aunt Trunchbull in Matilda, who not only abused her throughout her childhood, but also allegedly killed her father, Magnus.
- Jason Compson from The Sound and the Fury. He is cruel to his niece Quentin (as well as to almost everyone else) and he has been stealing the money her banished, suffering, hard-working mother Caddy sent for her, without having even the excuse of being poor.
- In Stardust, The Reveal is that the scheming and fratricidal Seven Princes of Stormhold were actually Tristran's uncles. Although they're not the primary villains.
- Closely done with the Elf Maeglin in "The Silmarillion". While not Earendil's uncle, he is the cousin of their mother Idril, who he desires. During the Fall of Gondolin he attempts to murder the 7-year old Earendil and take Idril, but her husband Tuor throws him off the walls. Interestingly enough Maeglin also technically counts as an Evil Nephew, as his betraying Gondolin leads to the death of its King, his Uncle Turgon. It is thought Maeglin's attempt to kill Earendil may be partially resentment that it ruins his chances of succeeding Turgon and anger that his cousin married a man, who he thought little of.
- A Song of Ice and Fire:
- As far as most of the Seven Kingdoms are aware, King Joffrey has a whole parade of Evil Uncles, including the usurpers Renly and Stannis Baratheon, the "twisted little monkey demon" Tyrion Lannister who is eventually convicted of Joffrey's murder, and the bloodthirsty Jaime Lannister. The subversion is that none of them are actually evil uncles: The Baratheons aren't really Joffrey's uncles since Joffrey wasn't fathered by Robert, Tyrion actually cares for his nephew, Jaime is also Joffrey's ''father'' and, while not a straightforward hero, is a far more morally complex character then he first appears, trying to take the throne out of his sense of duty. Renly may play this slightly more straight as he was planning on overthrowing Joffrey while thinking they were his nephew, though ironically despite being the most villainous of this four he is the most well-liked, partially because he died before he could dethrone Joffrey and it is believed his ghost helped defeat Stannis. And while none of the four are saints, Joffrey is much more evil than all of them put together, with Jaime even thinking that Joffrey deserved to die and Tyrion, though knowing Joffrey's younger brother Tommen would probably be a better King, will not kill Joffrey despite Joffrey delighting in tormenting him.
- Semi-averted and played straight in Theon and Asha Greyjoy's case. Their uncles Aeron and Victarion are no more evil than any other Ironborn, don't have any particular grudge against their niece and nephew, and are fanatically loyal to their father Balon. Aeron does oppose Asha inheriting the Seastone Chair after Balon's death despite their wishes, but this is because of his religious belief that a woman can't sit the Seastone Chair. Their uncle Euron, on the other hand, raped one brother's wife and is heavily implied to have molested the other as a child. When he wins the throne of the Iron Islands, Asha makes sure to be as far away as possible as quickly as possible, on the advice of her favorite uncle Rodrik Harlaw, who knows she threatens Euron's power. We hear that among the Ironborn it is not unusual for an uncle to dethrone and murder a weaker nephew.
- Arnolf Karstark's nephew (and liege lord) is taken hostage by the Lannisters in an attempt to force his allegiance. Instead, he declares against the Lannisters, not out of defiance but hope that Lord Harrion will be executed, leaving his sole surviving daughter the heir so Arnolf's son can forcibly marry her. And then, for good measure, he plans to betrays his sworn king Stannis as well.
- From the early Targaryen dynasty was Maegor the Cruel, son of Aegon I Targaryen. After his half-brother Aenys died he claimed the throne and killed two of Aegon's sons. He was thought to be the cruellest Targaryen King (till Aerys II over 200 years later). The youngest son of Aegon, Jaehaerys I, led a successful rebellion and Maegor died mysteriously before Jaehaerys reached King's Landing, many thinking Maegor killed himself with the Iron Throne.
- Viserys II was suspected of having his well-liked nephew Baelor the Blessed poisoned. However, it looks more likely Baelor died from his excessive fasting. Also, Viserys was the one really running the Seven Kingdoms as Hand of the King during their reign as his nephew's excessive piety meant he wasn't an efficient King, and Baelor may have intended to try converting all the Seven Kingdoms, which would have caused trouble with the North and the Iron Islands.
- Visenya Targaryen is suspected of having her nephew and stepson Aenys (due to Aegon marrying both his sisters) poisoned so her son Maegor could succeed ahead of Aenys' sons.
- The Babes in the Wood were exposed in the forest by their evil uncle, and died there.
- In Dan Abnett's Gaunts Ghosts novel First & Only, Gaunt's "Uncle Dercius" is not a real uncle, and does his best to look out for Gaunt. However, in the end, this was because Gaunt's father had died because of Dercius's cowardly flight from battle.
- In the Enchanted Forest Chronicles, the Right Honorable Order of Wicked Step-mothers has a male auxiliary for Evil Uncles.
- The one who appears in person is Prince Rupert of Meriambee, a Card-Carrying Villain who's really quite fond of his nephew Prince Jorillam but has to do something wicked to keep his membership in the Wicked Stepmothers' Travelling, Drinking and Debating Society (Men's Auxiliary). (Jorillam, by the way, knows all about this and constantly encourages his uncle to abandon him in the forest so he can have adventures.) So the solution is: abandoning him in the woods is not wicked, because he wants it. Send him to school instead!
- Cutter Amberville in I'll Take Manhattan, who is really pissed off because he wasn't born first compared to his "perfect" brother. Thus, he proceeds to knock up his brother's wife, molest his niece a little, cheat on his own wife with her sister (causing her to kill herself), and that's what he gets up to before he starts re-enacting Hamlet.
- In James Thurber's The 13 Clocks, the duke sets Impossible Tasks to the princes who want to marry his niece and kills many of them.
- The uncle of Uhtred in Bernard Cornwell's Saxon novels stole his title and fortress.
- Inverted in Fate/Zero, where Sakura's adoptive uncle Kariya sacrifices his life in an attempt to save her from her adoptive father and grandfather.
- Red's Uncle Richard in Juliet Marillier's Daughter of the Forest. He's so determined to get his hands on Red's land by marrying him to his daughter that he tries to murder his younger nephew, whom his daughter actually loves, then tries to murder the heroine when she foils his plans by marrying Red.
- Laharl’s aunt Yasurl from the Disgaea novels wants him of the throne because he is half human. If Laharl don’t step down she would prefer him dead, so she tries to have him assassinated.
- The Reynard Cycle: Corvino, the Countess Persephone's uncle by marriage, is perceived to be this by many people. Persephone herself believes that he was the source of the numerous attempts on her life over the years, in order that he might inherit her title. Turns out, it was actually her cousin, Celia, who wanted her dead.
- Thantos and Fredo DuBaer of T*Witches. Fredo kills his brother Aron, who is father to the protagonists of the series, Alex and Cam. Thantos tries killing his nieces multiple times, and tries to marry their mother. In the movies (TV movies on the Disney Channel), there is no Fredo, it is Thantos who kills Aron, along with trying to kill Alex and Cam.
- Goosefeather in Warrior Cats. Apparently. The whole scene was somewhat of a Mind Screw.
- Judith's uncle Robert de Belleme from The Wild Hunt Trilogy.
- Marina's aunt Arachne in The Gates of Sleep by Mercedes Lackey.
- In Teresa Frohock's Miserere: An Autumn Tale, Lucian and Catarina's Back Story revolves about this.
- Here Comes Santa Claws, the second of the two Christmas Episode books in the Graveyard School series, had Kyle Chilton dealing with a so-called evil great aunt looking after him for a few days before Christmas. This is a subversion in that said aunt hadn't actually done anything to him yet when she arrived, and Kyle was acting like a spoiled brat because he thought she was going to "ruin his Christmas". Which makes all the magical havoc she wreaked on him justified. Of course, it's implied that she's the distantly related great aunt of numerous children and she enjoys causing a little holiday mischief on the ones who cause trouble unprovoked. Her name, Mab, is a reference to the fairy queen Mab, so it seems only natural that she would be a Karmic Trickster.
- Baron Harkonnen from Dune is evil and an uncle, but he's surprisingly not a straight example of this. He's well aware of his own mortality and he wants to raise a worthy heir to the Harkonnen name. Since he's gay and he has no desire to father children of his own, he looks to his nephews instead. He's still willing to throw his nephew Glossu Rabban to the wolves to help his other nephew Feyd-Rautha Harkonnen's rise to power.
- Arguably, this is an inversion—he is in fact the maternal grandfather of Paul Atreides, i.e. his sworn enemy; he's more evil to his own (unwitting) progeny than to his nephews. Admittedly, the Bene Gesserit did essentially blackmail him into giving his genes...
- In Marissa Meyer's Lunar Chronicles, which is a retelling of the Cinderella story, uses an "evil aunt" as a plot twist. Towards the end of the book, the heroine, Cinder, learns that the wicked Queen Levana, who has been trying to entrap Prince Kai, is her mother's sister.
- Kidnapped by Robert Louis Stevenson has Ebenezer Balfour, uncle of protagonist David, a miser who plots to murder his nephew. When that fails, he arranges to have him sold into slavery.
- Fanny Price of Mansfield Park is sent to live with her mother's sister's family when she's ten-years-old. Although her uncle Sir Thomas Bertram is stern and intimidating, he's still a decent man who cares about his niece as much as his children. Her mother's other sister Mrs. Norris, on the other hand, could give Jane Eyre's Mrs. Reed a run for her money in the Cruelest Evil Aunt category.
- In 1066 and All That, King John, by murdering his little nephew, becomes "the first memorable wicked uncle" in English history.
- The brother of the King in the Goosebumps book A Night in Terror Tower usurped the throne by killing the rightful King and Queen, and arranging to execute their children, Edward and Susannah of York, Eddie and Sue's real identities.

He abuses her for five years, to the point of bullying her into marriage with a man, who's like forty years older than her and treats women like dirt under his shoes. Wilhelm's attempts to break Beatrice down into becoming a subservient woman includes threats, nearly starving her to death and direct physical violence.

Oh, and let's not forget that although this failed spectacularly, Uncle Justin left behind a doppleganger who resurrected the necromancer and then forced the necromancer to steal the nephew's life force and implant it in Morningway's corpse.
- In I, Claudius, Emperor Caligula is technically this before he becomes an Uncle. He impregnates his sister, but thinks he and his sister are Gods, so tries to imitate the birth of Athena by cutting the child out of her womb and eating it. Then there is his Great-Uncle Tiberius, who apparently murdered his nephew Germanicus, Caligula's Father, as he was more popular. It turns out that Caligula assisted with his father's murder and one of his henchmen ends up murdering Tiberius so Caligula can become Emperor.
- The primary antagonists of the first season of Teen Wolf and the fourth season as well are Derek's evil uncle Peter, who wants to subdue everybody under his alpha powers, and Allison's evil aunt Kate, who kills innocent people in contrast to the more lawful Hunter's Code. In contrast, the major parents shown in the series (Scott's mom, Stiles's dad, Allison's father) are strictly on the side of good.
- In ABC's Once Upon a Time, this trope frequently occurs. The most recent (Gender Flipped) example is The Snow Queen, an apparently evil sorceress who is purportedly Elsa and Anna's maternal aunt.
- Justified: Johnny Crowder definitely has this opinion of his Uncle Bo, who crippled him with a shotgun blast to the gut. Of course, Johnny himself is a criminal who was setting Bo up to take the fall for his, and his cousin Boyd's actions, so while Bo's certainly evil, his attitude towards Johnny is fairly understandable.

Once either of them is defeated (and in Shenmei's case, she recovers her memories), they die in peace and speaking to them kindly.
- Wilfred Hermeien from The Last Remnant. He is Marina's brother, making him Irina and Rush's uncle, who's willing to use Irina's power to control the Remnants of the world. Bonus points for seriously threatening to feed her to his pet Harpylia at one point, and pulling a knife on her at another.
- X-Wing Alliance, Ace's uncle Antan sides with the Empire.
- Heiss from Radiant Historia winds up hitting almost every point in the description. Jealous, childless younger brother? Check. Royalty? Check. Cain and Abel? Check. Ex-Cool Uncle? Check. Repeatedly tries to kill his niece and sends his nephew out on blatantly impossible missions? Check. However, twisting the trope a bit, he deeply and genuinely loves his nephew and considers himself a Stealth Mentor. As far as he's concerned his niece can go die in a fire, though.
- Unavoidable in Crusader Kings, since all children who don't inherit a title will get a claim to the title. So if your character dies, all your former brothers become this trope. It is rather common that your uncle takes up arms to get the title by force. Unless you take another succession law where your heir isn't your child, but that opens another can of worms.
- Far Cry 4: PAGAN MIN. He's the self-appointed "King of Kyrat", a dictator of a small drug-manufacturing country who kills citizens for fun and profit. He also has his ex-girlfriend's son kidnapped and transported into the house of a slave torturer to dine on Crab Rangoon together. Ajay's first instinct is to run. He then gives out hints that "Uncle Pagan" is setting up Ajay as his heir... even though neither of them are blood related or royalty. He's not joking.
- Princess Natasha, a web cartoon on AOL's kids' page, starred a teenage princess of a foreign country who is transferred to the United States to be a secret agent as a student of a high school, where her evil uncle is the principal.
- Avagadro Pompey of Something*Positive sexually and verbally abused his nephew Ollie, who was pathetically grateful as Avagadro had "saved" him from physical abuse at his father's hands.
- In Thistil Mistil Kistil, Coal's back story has some evil uncles in it.
- The trope image is Richard III, as depicted in Hark A Vagrant, of whom urban legend credits with murdering his two nephews. While a historian in the comic points out that many other historical figures had reason for killing the boys, Richard's already killed one.
- Inverted in Avatar: The Last Airbender, where Zuko's father is the evil, younger brother who stole the throne, while his uncle is a genuinely nice, caring person. Zuko himself said his uncle was more of a father figure to him when he was Calling the Old Man Out.
- Interestingly, though, Iroh was originally this while the show was still in design. Before he was redesigned into the tea-loving, Pai Sho playing Big Fun that we all know and love, he would have taught Zuko incorrect firebending on Ozai's orders and fought Zuko in season 3. Ozai would've become this to Lu-Ten, Iroh's late son.
- Played straight in The Legend of Korra with Unalaq, Korra's uncle. Not only does he fix the trial to get Tonraq sent to prison for life, but he also arranged for him to be exiled by paying barbarians to attack the city and hide in the spirit forest, which Tonraq destroyed. When Korra finds this out, she turns against him and calls him out on his jealousy. He also trained Korra for his own desires unlike Iroh, who genuinely cared for his nephew Zuko. Not only that, but he appears to be a neglectful father as well, such as leaving an injured Desna on the ground just to try and open the Spirit World portal. The constrast between Iroh and Unalaq becomes more evident in the episode "A New Spiritual Age", when both appear in diferent moments.
- Then he fuses with Vaatu, becoming Korra's Evil Counterpart, the Dark Avatar.
- The Shadow Master from the Double Dragon TV series. In one episode, Mrs. Lee, the mother of Billy and Jimmy makes an appearance. She reveals that not only is she their mother, but the main villain, the Shadow Master is none other than her brother, making him the twins' uncle.
- Limburger from Biker Mice from Mars, although his nephew Marshall is even worse.
- A reference in the Masters of the Universe tie-in comics indicate that Skeletor is actually King Randor's long-lost brother Keldor. This would make him Prince Adam/He-Man's uncle.
- Cody's uncle from Teenage Mutant Ninja Turtles: Fast Forward.
- Hex in Ben 10 to his Dark Magical Girl niece Charmcaster.
- In Batman: The Brave and the Bold, Aquaman's first episode features his brother, who despite having rebelled against him in the past, is accepted back some years later. He immediately tries to usurp Aquaman's crown again.
- In the animated "Fatman" segments of the The Weird Al Show, Fatman had an Evil Uncle Frank who was intended to be a recurring villain.
- In Codename: Kids Next Door, it turns out that Father (AKA the Big Bad) is the uncle of Numbuh 1, as he and Monty Uno (Numbuh 1's father) are brothers.
- The Professor is the enemy of Felix the Cat. But his nephew Poindexter is friends with Felix.
- Rambo: The Force of Freedom:
- "Reign of the Boy King": Black Duke Lucan wants to usurp the throne of Morovia from his nephew King Alexander.
- "Robot Raid": Merick wants to prevent his niece Jennifer from inheriting the family's company.
- Punky Brewster discovers she has an aunt and an uncle in "Punky the Heiress," and they've offered to reunite her with her missing mother. But (a) they're actually servants for the Chester Henderson estate, and (b) they're using Punky to embezzle the inheritance of Henderson's granddaughter, of whom they have Punky dressed up to look like.
- All Hail King Julien has Julien's uncle, King Julien XII. In the pilot, he passes the crown to his nephew because the king was predicted to be sacrificed to the fossa. He returns in the fifth episode to take back his reign, sending Julien to be unwittingly eaten by the fossa, and removes all the fun things his nephew did for the kingdom.
