->''"How come the kindest parents always have the most dickass relatives?"''
-->-- '''WebVideo/TheNostalgiaCritic''', reviewing ''Film/JamesAndTheGiantPeach''

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 or mother has a tendency to be evil. No-one is exactly sure why, given that the two were raised in the same environment and its not InTheBlood for everyone. Maybe simply because of [[GreenEyedMonster envy]], and because the uncle will [[{{Greed}} stand pretty high in the succession row]].

The concept stems far back to the medieval days, where the firstborn son is the crown prince, [[SpareToTheThrone 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 MiddleChildSyndrome -- though in most media, there's only two brothers in the first place, if only to avoid cluttering up the story.

One result of this arrangement is that if the ruler dies while the heir is too young to take over, the old monarch's younger brother (i.e. the new monarch's uncle) would probably become [[EvilRegent the interim de facto ruler]], and would be well positioned to take the crown permanently if [[InheritanceMurder something unfortunate were to happen]].

This has a tendency to escalate to CainAndAbel; in fact, it almost always does. If he is from a royal family, which he frequently is, he is most commonly TheEvilPrince. 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 TheQuest for an ImpossibleTask; this is usually [[EvilOverlordList unwise]].

A female equivalent is likely to be the WickedStepmother; she is unable to inherit herself, but her children can. When your mom and dad are the problem, see EvilMatriarch and ArchnemesisDad.

Can overlap with CoolUncle (see: EvilIsCool), in this case, the uncle himself might be a FreudianExcuse for a character's StartOfDarkness or FaceHeelTurn. He rarely is a CreepyUncle, however, though some measure of overlap with that trope is possible depending on the uncle. Contrast with EvilNephew.

A common way to give a character a terrible childhood [[TraumaCongaLine all in one go]] is to [[DeceasedParentsAreTheBest kill off their (invariably wonderful) parents]] and send them to live with their EvilUncle (and/or their Evil Aunt) -- the dark side of {{Nephewism}}.


[[folder:Anime and Manga]]
* In the original Manga/ShamanKing, Ren has an evil father. In the [[{{Creator/FourKidsEntertainment}} 4Kids version]], he's Ren's ([[DubNameChange Len's]]) uncle.
* Richard Hellsing (has anyone noticed [[WhatDoYouMeanItsNotSymbolic the symbolism?]]), the younger brother of Arthur Hellsing in the [[Manga/{{Hellsing}} 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 daughter, but that just means Richard has to get little Integra out of the way. Unfortunately for him, he didn't account for a certain [[SealedEvilInACan family heirloom]]...
* V.V. of ''Anime/CodeGeass'' is very much an EvilUncle to Lelouch and some of his siblings like Cornelia, being the ManBehindTheMan to Emperor Charles.
* Rido from ''Manga/VampireKnight'' is this to the protagonist Yuuki Kuran, specially when he [[spoiler: becomes obsessed with Yuuki herself, to the point of ''[[ParentalIncest wanting to make her his wife]]''.]]
* ''Literature/KemonoNoSoujaErin'' has Damiyah, who is quite charming when he isn't coldly threatening.
* In ''Manga/VinlandSaga'' it's revealed that Thorkell, considered a lunatic BloodKnight by his fellow Vikings, is actually [[spoiler: Thorfinn's great-uncle.]]
* ''Manga/{{Naruto}}'':
** The Sand siblings uncle [[DeadlyDoctor Yashamaru]], [[spoiler: or so it seems. He was ordered to ''pretend'' to be evil]].
** Neji viewed Hinata's father Hiashi as this for a good portion of his life. He eventually learns he's not as bad as he seems [[spoiler:and he didn't force his twin brother to die in his place]].
* Raditz, the first villain that appeared in ''Anime/DragonBallZ''. 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 StarterVillain, he doesn't get that far.
** Ditto Turles, at least [[DependingOnTheWriter in those dubs]] where he's Goku's ''other'' brother. [[ShrugOfGod It's vague.]]
* In ''Manga/TokyoGhoul'', Ken Kaneki's maternal aunt is this combined with a hefty dose of WickedStepmother. She constantly went to her widowed, ExtremeDoormat 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... yeah, the woman 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 ''Another Monster'' (a follow-up to ''Manga/{{Monster}}''), the revelation that Johan and Anna's late father was the brother of [[spoiler: Franz Bonaparta]] means that [[spoiler: Bonaparta]], the main figure who engineered the twins' birth at the expense of their father's life and arguably helped cultivate Johan into the person he is, was actually their own uncle all along.
* ''Manga/DetectiveSchoolQ'' has a case that includes an Evil Aunt. [[spoiler: Sachiyo Ichinose is a greedy SmugSnake who wants to place her paws in the hefty inheritance that her teenage niece Kaoru will get after the death of her ''very'' rich mother, Hanayo. However, Kaoru's {{knight templar big brother}}s Kunihiko and Akihiko are willing to do ''anything'' to protect Kaoru from Sachiyo's machinations... up and including ''murder''.]]
* In ''Manga/RoseOfVersailles'', the Count of Provence and the Count of Artois, Louis XVI's younger brothers, react to their nephew Louis Joseph' slow death by tuberculosis by hoping he'll just hurry up and die, and spread lies about the legitimacy of Louis XVI's other son in the hope they'll be thus able to succeed to the throne of France. Much annoyingly, they succeed thanks to UsefulNotes/TheFrenchRevolution

[[folder:Comic Books]]
* ''Comicbook/{{Shazam}}'': In a short-lived '80s reboot ''ComicBook/ShazamTheNewBeginning'', Billy "Captain Marvel" Batson's arch-nemesis [[MadScientist Doctor Sivana]] was revealed to be his step-uncle. This was undone a few years later. Note that back in UsefulNotes/TheGoldenAgeOfComicBooks, 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 ''ComicBook/XMen: The Hidden Years'', a series that chronicled early, apocryphal adventures of the original team of ComicBook/XMen, 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.
* [[ComicBook/DisneyDucksComicUniverse 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 [[KarmaHoudini he almost always gets away with it.]]
* Franchise/TeenTitans: 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 Comicbook/DoomPatrol, and the Patrol had no problem telling the guy to pick on someone his own size and power level...
* ComicBook/{{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.
* Nasthalthia 'Nasty' Luthor was a criminal who tried to make Comicbook/{{Supergirl}}'s life impossible back in the Silver Age. Her uncle is Comicbook/LexLuthor, one of the main super-villains of Franchise/TheDCU.
%%* Comicbook/SwampThing's archenemy Anton Arcane more than fulfills this role towards his niece Abby.
* Jarvis Kord, uncle to the second Comicbook/BlueBeetle, and one of his more dangerous enemies.
* ''ComicBook/{{Arawn}}'': Fenris tries to usurp his nephew Arawn's throne after he's become an EvilOverlord. Of course, since he's already a virtual deity by this point, Fenris' insurrection is squashed pretty quickly.

[[folder:Fairy Tales]]
* In "Literature/TheTwoBrothers", collected by Creator/TheBrothersGrimm, the twin brothers' uncle is a wicked and greedy man, though not especially more so to his nephews than to anyone else.

* The Dark Man, aka [[spoiler: Gordon Freeman]] to Henry Freeman, in ''Fanfic/HalfLifeFullLifeConsequences''.
* Tabitha's uncle in ''Fanfic/PointsOfFamiliarity'' keeps sending Tabitha on impossible missions to get her killed. She insists on not only surviving these missions, but successfully completes them.
** This isn't an example specific to this fic. Tabitha's relationship with her uncle is canon.
* Some fanfics of ''WesternAnimation/AvatarTheLastAirbender'' suggest that Ozai might have had something to do with his nephew Lu Ten's death.
* In the Fanfic/TheShadowWars Story Verse of WesternAnimation/MyLittlePonyFriendshipIsMagic, Fluttershy's Uncle Windvane, a Pegasus supremacist who launches a major armed rebellion against Equestria and routinely murders captive civilians to drain their LifeEnergy by means of his Pegasus Device, certainly qualifies.
* An Webcomic/AxisPowersHetalia fic, [[http://.fanfiction.net/s/8744418/1/The-Danish-Slaughterhouse The Danish Slaughterhouse]] has Denmark [[spoiler: plotting the murders of his family and raping his nephew, Sealand several times.]]

[[folder:Films -- Animated]]
* Scar from ''Disney/TheLionKing'' is probably one of the most famous examples, murdering his brother and afterwards attempting to murder his nephew in order to take the throne, all based on ''Theatre/{{Hamlet}}.''
* Hades from Disney's ''Disney/{{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 [[HijackedByJesus 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. Granted, Hera is Hercules's aunt.
* Ursula from ''Disney/TheLittleMermaid'' 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.
* In ''WesternAnimation/FelixTheCatTheMovie'', the main antagonist the Duke of Zill is Princess Oriana's uncle.
%%* The Grand Duke from ''WesternAnimation/RockADoodle'' is an evil uncle to comic relief villain (and arguable [[TheScrappy scrappy]]) Hunch.
%%* Laird from ''WesternAnimation/ThePrincessAndThePea''.
%%* Yet another Evil Aunt--Aunt Figg, from ''WesternAnimation/TomAndJerryTheMovie''.

[[folder:Films -- Live-Action]]
* Sir Edgar from ''Film/EllaEnchanted'' is one of these to Prince Char. [[spoiler:In grand Hamlet fashion, he murdered Char's father in order to become King]].
* Uncle Charlie from the film ''Film/ShadowOfADoubt'' is one of the first major examples of a psychopath in cinema and a very [[CreepyUncle creepy]] and [[EvilUncle evil uncle]].
* In ''Film/{{Stardust}}'', TheReveal is that [[spoiler: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 TheFilmOfTheBook.
* There's the obligatory Evil Uncle in ''Film/StrangeBrew'', but that's really just because it's a humorous retelling of ''Theatre/{{Hamlet}}''.
* Played effectively by Judith Anderson in ''Film/TheStrangeLoveOfMarthaIvers''.
* In ''Film/TheLibrarian 2'', Flynn's Uncle Jerry is a lovely man who Flynn idolised growing up until TheReveal when he becomes a SmugSnake out for revenge [[spoiler: and is revealed to have killed Flynn's father.]]
* Frank from ''Film/{{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 [[IncestIsRelative turning his attentions to Kirsty]]. Numerous times, he's shown trying to rape her, including a scene where they ''[[{{Squick}} kiss]]''.
* Dastan's uncle in the ''Film/PrinceOfPersiaTheSandsOfTime'' movie. [[spoiler:His ultimate goal is to turn back time so that he can let his brother die as a teenager and reign in his stead.]]
* Sam Harper of ''Film/UncleSam'' is a sadistic door gunner who was shot down in Iraq, and to the horror of the rest of the Harper family goes on a psychotic murder spree from the grave.
* Michael Myers from the ''Franchise/{{Halloween}}'' series tries to kill his niece Jamie in the [[Film/Halloween4TheReturnOfMichaelMyers fourth]] and [[Film/Halloween5TheRevengeOfMichaelMyers fifth]] movie, and his nephew John in ''Film/HalloweenH20TwentyYearsLater''.
* Jason Voorhees is upgraded into one in ''Film/JasonGoesToHellTheFinalFriday'' as he suddenly has more relatives and has to possess one them to return back to life properly. Oddly, when given the chance he ignores his niece and tries to possess his ''grand''-niece instead.
* The Fallen is this to Opimus Prime in ''Film/TransformersRevengeOfTheFallen'', although there might be a few greats in there, how many generations separate the two isn't made clear.
* Bo Baker's Uncle Bill from ''Film/HighStakes'', 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.
* ''Film/UncleSilas'' 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 ''Film/PrincessOfThieves'', and plots to keep Philip from ascending the throne.
* In ''Film/LegendOfTheBlackScorpion'', due to being an adaptation of ''Hamlet''. Uncle kills father, takes power, tries to kill nephew.
* Uncle Les in ''Film/BrainDead'' is a repulsive sleazy JerkAss who tries to blackmail Lionel out of his mother's estate.
* Kevin's Uncle Frank in ''Film/HomeAlone'' 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. In fact, [[WhatCouldHaveBeen the original draft]] for the first movie was going to have Uncle Frank as a straight-up villain, who hired Harry and Marv to knock over the [=McAllister=]s' house in exchange for a cut of the loot.
* ''Film/{{Purgatory}}'': Sonny's uncle, a ruthless bandit and rapist. In the end he tries to gun his own nephew down.

* Hades as portrayed in the actual myths is [[DarkIsNotEvil 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 [[AlternateCharacterInterpretation depends on the character interpretation.]]
** Though at least he asked her Father (his brother) first, which was more than Zeus often did.
** Gender-Flipped with the Goddess Hera, who often tortured her brother, Zeus's, children. [[BrotherSisterIncest Since she was also his wife]], she literally doubles as a WickedStepmother.
* OlderThanDirt: Set, the [[Myth/EgyptianMythology 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 [[Myth/HinduMythology 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 Myth/NorseMythology, 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).

* ''Literature/{{Phenomena}}'' has an interesting take on this where [[spoiler:[[TheDragon Tarkan]]]] is actually the [[TheChosenOne Chosen Ones]]' [[HappilyAdopted adoptive]] father Sha-ra's younger brother Mentor, making him pretty much this. [[spoiler: Interestingly does he take a HeelFaceTurn to help out when Sha-ra [[TearJerker dies]] to make up for his sins.]]
* Inverted in ''Literature/DragonBones''; 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 ''Franchise/HarryPotter''. 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.
* ''Literature/JaneEyre'' gives an interesting case of this. Jane's aunt is a WickedStepmother 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 [[spoiler: and another that left Jane an inheritance.]]
* In [[Literature/ChildrenOfTheLastDays 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 [[spoiler: Trunchbull]] in ''Literature/{{Matilda}}'', who not only abused her throughout her childhood, but also allegedly killed her father, Magnus.
* Jason Compson from ''Literature/TheSoundAndTheFury''. 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.
* Miraz from ''Literature/PrinceCaspian'', and Digory's Uncle Andrew in ''Literature/TheMagiciansNephew''. [[spoiler: Andrew gets ''slightly'' better, Miraz doesn't and dies]]. Miraz only becomes one once he has his own son, though. Before that he was happy for Caspian to be his heir.
%%* Duke Roger from the [[Literature/TortallUniverse Song of the Lioness]] tetralogy, of the CoolUncle variety.
* In ''Literature/{{Stardust}}'', TheReveal is that [[spoiler:the scheming and fratricidal Seven Princes of Stormhold were actually Tristran's uncles. Although they're not the primary villains]].
%%* Wienis from ''Literature/{{Foundation}}''.
* Closely done with the Elf Maeglin in "Literature/TheSilmarillion". While not Earendil's uncle, he is the cousin of their mother Idril, who he [[KissingCousins desires]]. During the Fall of Gondolin he attempts to murder the 7-year old Earendil and [[IHaveYouNowMyPretty take Idril]], but her husband Tuor throws him off the walls. Interestingly enough Maeglin also technically counts as an EvilNephew, 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 [[FantasticRacism thought little of]].
* ''Literature/{{A Song of Ice and Fire}}'':
** As far as most of the Seven Kingdoms are aware, King Joffrey has a whole parade of {{Evil Uncle}}s: the usurpers Renly and Stannis Baratheon, the "twisted little monkey demon" Tyrion Lannister, who is [[spoiler: eventually convicted of Joffrey's murder]], and the bloodthirsty Jaime Lannister. The subversion is that none of them are actually evil uncles: [[spoiler:The Baratheons aren't really Joffrey's uncles since Joffrey wasn't fathered by Robert Baratheon, Tyrion actually cares for his nephew ([[EvilNephew at first]]), Jaime is also Joffrey's [[BrotherSisterIncest biological father as well as his uncle]] and, while not a straightforward hero, is a far more morally complex character then he first appears, Stannis is trying to take the throne out of [[ReluctantRuler his sense of duty]].]] Renly may play this slightly more straight as he was planning on overthrowing Joffrey [[spoiler:while thinking they were his nephew, though ironically despite being the most villainous of this four he is the [[VillainWithGoodPublicity 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 [[spoiler: deserved to die]] and Tyrion, though knowing Joffrey's younger brother Tommen would probably be a better king, will not kill Joffrey despite Joffrey [[EvilNephew delighting in tormenting him]].
*** Played with slightly more with Stannis. At one point, he considers burning one of his brother's illegitimate children, Edric Storm -- his nephew -- because, according to the Sorceress Melisandre, Edric's kingsblood will enable Stannis to raise a dragon. Stannis is encouraged in this by one of the uncles of his wife Selyse, Ser Axell Florent, even though Edric is one of Axell's great-nephews (King Robert seduced one of Selyse's cousins at Stannis' wedding). Stannis does eventually seem to come round to the idea of sacrificing Edric, but he is clearly very reluctant, only agreeing as he feels [[ResignedToTheCall it's his duty to become king]] and promises Melisandre that she'll die if this fails. Thankfully, his loyal adviser Davos Seaworth smuggles Edric away before Stannis can go through with this.
** Downplayed 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 [[spoiler:after Balon's death despite Balon's 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 [[spoiler: 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 [[CoolUncle 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. Similarly, we hear that Tristifer Botley's father Lord Botley of Lordsport was drowned by Euron for refusing to support their claim and Lordsport was given to Tristifer's uncle.
** Arnolf Karstark's great-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 in the hope that Lord Harrion will be executed, leaving Harrion's sister (Alys Karstark) the heir so Arnolf's son Cregan can forcibly marry her, making himself the Lord of Karhold. [[spoiler:And then, [[ChronicBackstabbingDisorder for good measure]], Arnolf plans to betrays his sworn king Stannis Baratheon as well.]] Cregan Karstark can also count as this trope since Alys Karstark has always referred to Cregan as her uncle and Cregan and Alys are referenced as uncle and neice in-universe, though he is the cousin of her father Lord Rickard Karstark's cousin. Cregan wants to forcibly marry Alys to become Lord of Karhold and Alys fears he'll kill her once she's given birth to an heir.
** From the early Targaryen dynasty was Maegor the Cruel, son of Aegon I Targaryen. After his half-brother Aenys died he claimed the throne, killed two of Aenys's sons, and married one of Aenys's daughters. He was thought to be the cruelest Targaryen King (till [[TheCaligula Aerys II]] over 200 years later). The youngest son of Aenys, Jaehaerys I ([[AChildShallLeadThem who was only 14 at the time]]), 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 [[WickedStepmother stepson]] Aenys (due to Aegon marrying both his sisters) poisoned so her son [[MotherMakesYouKing Maegor could succeed]] ahead of Aenys' sons.
** Happened during "The Dance of the Dragons", a civil war between two branches of House Targaryen from the two marriages of Viserys I. Hostilities really began when one of Rhaenyra's sons, Lucerys Velaryon, was killed by one of Rhaenyra's half-brothers, Aemond Targaryen, even though Lucerys had come as a messenger. For this Lucerys' stepfather Daemon Targaryen had one of Aegon II's sons, a half-nephew by marriage/great-nephew (he had married his niece Rhaenyra) killed. Later Daemon and Aemond killed each other in battle (Daemon's body was never found but it is very unlikely he survived). Aegon III, the oldest surviving son of Rhaenyra, was kept hostage by his half-uncle Aegon after Aegon II had Rhaenyra eaten by his dragon. When the war began turning against Aegon, he ordered his nephew's ear to be cut off, though was poisoned before this could happen, meaning his nephew became Aegon III.
** Brynden Rivers "Bloodraven" plays with this. When one of his half-brothers Daemon Blackfyre rebelled against their legitimate brother Daeron II Targaryen, Brynden slew Daemon and their two eldest sons with his arrows, though as they were rebels trying to overthrow the King and Brynden was supporting the King this could be justified. Later, at a Great Council to determine succession after the death of Daeron's youngest son Maekar I, another of Daemon's sons, Aenys, tried to make a claim. Bloodraven offered him safe conduct, but when he was in King's Landing Brynden had him executed. The new King, Maekar's youngest son Aegon V, exiled him to the Wall for this, not because of who he'd killed but because he'd broken the word of the Iron Throne.
** Tywin Lannister's grandfather Gerold Lannister became Lord of Casterly Rock after the sudden death of his brother Tybolt Lannister and shortly after Tybolt's daughter Cerelle died, meaning he was suspected of murdering them.
* The Literature/{{Babes in the Wood}} were exposed in the forest by their evil uncle, and died there.
* In Creator/DanAbnett's ''Literature/GauntsGhosts'' novel ''First & Only'', Gaunt's "Uncle Dercius" is [[HonoraryUncle not a real uncle]], and does his best to look out for Gaunt. However, in the end, this was because [[spoiler: Gaunt's father had died because of Dercius's cowardly flight from battle]].
%%* [[spoiler:Tenris]] in ''Literature/{{The Chronicles of Ancient Darkness}}''.
* In the ''Literature/EnchantedForestChronicles'', 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 CardCarryingVillain 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 [[JumpedAtTheCall have adventures]].) [[spoiler: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 [[WhosYourDaddy 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 Creator/JamesThurber's ''Literature/The13Clocks'', the duke sets {{Impossible Task}}s to the princes who want to marry his niece and kills many of them.
* Jasper in Creator/CharlesDickens's unfinished ''Literature/TheMysteryOfEdwinDrood'', who is [[spoiler:the murderer, according to reports from Dickens' friends and relatives]].
* The uncle of Uhtred in Bernard Cornwell's ''[[Literature/TheSaxonStories Saxon]]'' novels stole his title and fortress.
%%* In Creator/LewisCarroll's ''Literature/SylvieAndBruno'', the Sub-Warden, Sibimet.
* Inverted in LightNovel/FateZero, where Sakura's [[spoiler:adoptive]] uncle Kariya sacrifices his life in an attempt to save her from her [[spoiler:adoptive]] [[AbusiveParents father and grandfather]].
%%* J. Sheridan le Fanu's ''Uncle Silas''.
* Red's Uncle Richard in Juliet Marillier's ''Literature/DaughterOfTheForest''. He's so determined to get his hands on Red's land by [[KissingCousins marrying him to his daughter]] that he [[spoiler: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]].
* [[Characters/DisgaeaHourOfDarkness Laharl’s]] aunt [[Characters/DisgaeaNovels Yasurl]] from the [[LightNovel/DisgaeaNovels Disgaea novels]] wants him of the throne [[FantasticRacism because he is half human]]. If Laharl don’t step down she would prefer him dead, so she tries to have him assassinated.
* ''Literature/TheReynardCycle'': 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. [[spoiler: Turns out, it was actually her cousin, Celia, who wanted her dead.]]
* Thantos and Fredo [=DuBaer=] of ''Literature/TWitches''. 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.
* Judith's uncle Robert de Belleme from ''Literature/TheWildHuntTrilogy''.
* Marina's aunt Arachne in ''Literature/TheGatesOfSleep'' by Creator/MercedesLackey.
* In Teresa Frohock's ''Literature/MiserereAnAutumnTale'', Lucian and Catarina's BackStory revolves about this.
* ''Here Comes Santa Claws'', the second of the two ChristmasEpisode books in the ''GraveyardSchool'' 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". [[spoiler: 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 KarmicTrickster.]]
* Baron Harkonnen from ''Franchise/{{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--[[spoiler: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 Literature/LunarChronicles, 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.
* ''Literature/{{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 ''Literature/MansfieldPark'' 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 Literature/JaneEyre's Mrs. Reed a run for her money in the Cruelest Evil Aunt category.
* In ''Literature/TenSixtySixAndAllThat'', King John, by murdering his little nephew, becomes "the first memorable wicked uncle" in English history.
* The brother of the King in the ''Literature/{{Goosebumps}}'' book ''A Night in Terror Tower'' usurped the throne by killing the rightful King and Queen, and arranging to execute their children, [[spoiler:Edward and Susannah of York, Eddie and Sue's real identities.]]
* [[FatAndSkinny Aunt Sponge and Aunt Spiker]] from ''Literature/JamesAndTheGiantPeach'' are evil aunts.
* ''Literature/GloryInTheThunder'' has a rare maternal uncle example in Vahagn, the God of Secrets.
* Swedish writer Simona Ahrnstedt gives us Wilhelm Löwenström in her debut novel ''Literature/{{Overenskommelser}}''. While even his treatment of his own children has been awful in the past, he now has his niece Beatrice as his favorite victim. 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.
* Coryn from ''Literature/GuardiansOfGaHoole'' was raised by his mother Nyra to believe Soren was this, having killed his father Kludd. But a later vision tells him of the inversion of this trope: Kludd was trying to kill Soren only to be killed in return by Twilight. After finding out the truth, Coryn rejects the harsh ideals of his father and accepts the kinder truth about his uncle.
* Beause collecting billions from his EvilPlan is somehow not enough, Dr. Anton Murik in ''Literature/LicenceRenewed'' plans to assassinate his ward, a daughter of his half-brother, for her inheritance.
* The uncle from ''Babes In The Woods'', who hires two thugs to kill his nephew and niece so he can be rid of them and reap his dead brother's fortune.
* Edwarn Ladrian from ''Literature/WaxAndWayne'' is this to his nephew Waxillium. At first, he tried to raise his nephew as a worthy (in his eyes, meaning ruthless) heir of the family fortune, but Waxillium rebelled and ran away. Later, he would stop at nothing, up to killing his nephew - who in turn just wants to bring him to justice for his crimes.
* In ''Literature/TheMadKing'' by Creator/EdgarRiceBurroughs, Prince Peter is regent to his nephew, the boy king Leopold. He has Leopold locked away, announces that the boy has lost his wits from grief at his father's death, and attempts to set himself up as RegentForLife.
* ''Literature/TheSagaOfTheFaroeIslanders'': For personal gain, Thrand of Gotu participates in the murder plot against his own cousins Brestir and Beinir, and sells their sons Sigmund and Thorir into slavery, thus setting off their life-long conflict. When Sigmund returns to the islands triumphantly, Thrand fakes remorse and tries to capitalize on his blood ties to Sigmund to escape punishment, but weasels out of the peace agreement as soon as the opportunity presents itself, and again plots against Sigmund. Thrand's behaviour contrasts with that of Sigmund, who spares Thrand's life twice on account of their kinship, even though he knows Thrand feels no such compunctions.
* ''Literature/SansFamille'': BigBad James Milligan is the uncle of protagonist Remi.
* ''Literature/WingsOfFire'': Tsunami's uncle Shark is a commander in the [=SeaWing=] army, and he's very grouchy and aggressive. So much so that Tsunami suspects that he might've been the one to kill most of Queen Coral's daughter so that he could get the throne. This is eventually subverted, for despite his aggressive attitude, Shark ends up fighting loyally for the Sea Kingdom when under attack.
* In ''Literature/ACollegeOfMagics'', one of the obstacles Faris must deal with on the way to inheriting the Duchy of Galazon is a wicked and scheming uncle. It turns out he's not the one sending assassins after her, though, if only because he needs her alive a bit longer until his own plans mature.

[[folder:Live Action TV]]
* ''Series/GameOfThrones'': Deconstructed by Stannis and Renly Baratheon, who contest their nephew's claim to the throne. However, Joffrey is TheCaligula and neither the rightful king nor their nephew. Besides it takes more than just wanting to depose him to make them "evil."
** Played totally straight by Euron Greyjoy to Theon and Yara. He shows up to seize the throne of the Iron Islands by [[spoiler: killing his brother Balon]] and usurping Yara's right to it, then planning to kill both of them to eliminate a threat to his power.
* Count Dregon was ''Series/MaskedRider'''s uncle. Better yet, [[FanonDiscontinuity that never happened]].
* ''Series/PowerRangersNinjaStorm'': BigBad Lothor is revealed to be this to Cam, son of BigGood Sensei, during a time travel story. This is actually brought up more often than the fact that Lothor killed Hunter and Blake's parents.
--> "You can't choose your family, Lothor, and I certainly didn't choose you."
* Zor-El in ''Series/{{Smallville}}''
* Chuck's uncle Jack on ''Literature/GossipGirl'' is definitely evil. He doesn't particularly mind if his seventeen year-old, newly orphaned nephew falls off the rooftop of a building and he delights in ruining said nephew's life a year later. He's even called [[FanNickname Evil Uncle Jack]] by fans.
* The Nennog of ''Series/MaddigansQuest'' was this to Timon, Eden and Jewel; it's made clear from the start he wants them dead. [[spoiler:Well, Eden and Jewel, at least...]]
* The ''Series/TalesFromTheCrypt'' episode "Fitting Punishment" centres around a homeless, orphaned teenager being sent to live with his miserly uncle. The uncle treats him as slave labour, cripples him for life during a beating, and then murders him after deciding that the boy is costing him too much money. [[spoiler: Eventually the boy returns as a zombie and beats his uncle to death.]]
* Count Federico, in the ''Series/DoctorWho'' serial ''[[Recap/DoctorWhoS14E1TheMasqueOfMandragora The Masque of Mandragora]]''.
* As of Season 4, Prince Arthur from ''Series/{{Merlin}}'' has his uncle Agravaine, [[spoiler:who's secretly working with Morgana, partially in revenge for his sister dying birthing Arthur, and Arthur's father Uther killing his brother when they fought Uther over this]].
* The second-chance shelter cook was this in the ''Series/{{NCIS}}'' episode "Restless." For starters, he took custody of his niece after her parents were killed in a car crash.
* Justin Morningway from ''Series/TheDresdenFiles''. Among dear old Uncle Justin's crimes: arranging for his sister Margaret's murder ("she had dangerous ideas!")and, some years later, killing his brother-in-law with a voodoo doll in order to get custody of his magically gifted eleven-year-old nephew, whom he, with the help of a necromancer's cursed ghost, hoped to turn into a loyal political ally and supporter steeped in [[BlackMagic Black Magic]]. Oh, and let's not forget that although this failed spectacularly, Uncle Justin [[spoiler: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 ''Series/IClaudius'', Emperor UsefulNotes/{{Caligula}} is technically this before he becomes an Uncle. He [[BrotherSisterIncest impregnates his sister]], but thinks he and his sister [[AGodAmI 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 [[DirtyOldMan Tiberius]], who apparently murdered his nephew Germanicus, Caligula's Father, as he was more popular. [[spoiler:It turns out that Caligula assisted with his father's murder and one of his henchmen ends up murdering Tiberius so [[EvilNephew Caligula]] can become Emperor.]]
* The primary antagonists of the first season of ''Series/TeenWolf'' [[spoiler: 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 ''Series/OnceUponATime'', this trope frequently occurs. The most recent (GenderFlipped) example is The Snow Queen, an apparently evil sorceress who is purportedly [[Disney/{{Frozen}} Elsa and Anna's]] maternal aunt.
* ''Series/{{Justified}}'': Johnny Crowder definitely has this opinion of his [[CorruptHick 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.
* The Hood is this to Tin-Tin in ''Series/{{Thunderbirds}}'', though it is [[AllThereInTheManual never mentioned in the series itself]]. It is brought up more in ''Film/{{Thunderbirds}}'' the movie]] and the remake series ''WesternAnimation/ThunderbirdsAreGo''.
* In ''Series/TrailOfLies'', Felix Khoury is to his niece Paulinha at first, considering that he abandoned her in a trash bin when she was just a newborn, just because he didn't want to have to compete with anyone for his inherance.
* Subverted in ''{{Series/Blackadder}}'''s first season, which is set in an AlternateHistory where Richard III was a kind and loving uncle who was succeeded by one of the Princes in the Tower, and the EvilUncle and double murder history recorded was the result of a later king going back and falsifying records.

* There is a German band known as Boehse Onkelz, which translates as... well, you know.
* Music/TheWho's Music/{{Tommy}}'s Wicked Uncle Ernie. He molested Tommy when Tommy was a teenager, and exploits him after Tommy's cult becomes a religion.
* ''Music/UncleMeat'' by Music/FrankZappa was the intended soundtrack to "a movie we haven't got enough money for to make yet". In the liner notes of the album we find out that Uncle Meat is a MadScientist who wants to rule the world with an army of mutant monsters. He would return in the liner notes of ''Music/TheGrandWazoo''.

* In the backstory of ''VideoGame/MadDaedalus'', the Greek inventor Daedalus murders his nephew due to jealousy over the accolades the latter received.

[[folder:Tabletop Games]]
* ''TabletopGame/MagicTheGathering'' has [[http://gatherer.wizards.com/Pages/Card/Details.aspx?multiverseid=1743 Uncle Istvan]], from ''The Dark'' expansion. Although we only have the card's name to take for the fact that he is an uncle, his flavor text makes it clear that he is [[AxCrazy quite evil]].

* Creator/WilliamShakespeare's ''Theatre/RichardIII'' is one of the most famous examples of an uncle out to kill his nephew, so he can assume the throne himself.
%%* Creon from ''Theatre/{{Antigone}}'' is a subversion, assuming it doesn't count as an UnbuiltTrope. He's certainly ''against'' Antigone, but neither of them are at all ''evil'', simply torn between their obligations and loyalties.
* In the Broadway musical, ''Disney/TheLionKing'''s Scar believes that having heirs will make him feel complete as a king. It is in fact his guilty conscience about killing his own brother and exiling his nephew that makes him feel empty, but that doesn't stop him from [[{{Squick}} hitting on]] [[WifeHusbandry Nala.]]
* Claudius from ''Theatre/{{Hamlet}}'', generally considered the TropeCodifier.
* A rare evil aunt: Ursula from ''Theatre/TheLittleMermaid.'' This connection was cut from the movie, but it was restored for the Broadway musical.
* Aegisthus of ''Theatre/{{Electra}}'', being a close cousin who became Electra's step-father after murdering her dad and marrying her mom. He also plans to seal her up in a cave.
* Atreus in ''Thyestes'' is the definitive EvilUncle--he [[MoralEventHorizon feeds his nephews to their father]] to avenge Thyestes' affair with Mrs. Atreus.

[[folder:Video Games]]
* Franchise/FireEmblem has many examples:
** In ''[[VideoGame/FireEmblemJugdral Seisen no Keifu]]'', Prince Lewyn has ''two'' of these to contend with, Maios and Daccar. ([[spoiler: Though in the Oosawa manga, Daccar is shown to have some HiddenDepths and then goes the RedemptionEqualsDeath way]]). Later on Bloom is this to Tine [[spoiler: and if Tailtiu didn't have kids, to Linda]], though he isn't as cruel to her as [[EvilMatriarch his wife and Tine's Aunt, Hilda]] was. Hilda actually tortured Tine[[spoiler: or Linda]]'s mother to death and has children gathered up as {{Human Sacrifice}}s in her free time, lovely woman really. If the player pairs up Lex and Azelle with anyone, Danan and Alvis become Evil Uncles to their children.
** Lord Lundgren, younger brother of Lyndis's grandfather, Hausen, in ''[[VideoGame/FireEmblemElibe Fire Emblem: Rekka no Ken]]''. Lundgren desires his brother's position as Marquess and is angered by the possibility of Hausen reuniting with his longlost granddaughter. Thus to secure his inheritance, Lundgren has his brother poisoned, frames his grandniece as an imposter, and tries to have her assassinated.
** ''[[VideoGame/FireEmblemTellius Radiant Dawn]]'' manages to subvert this with [[spoiler: Queen Elincia's uncle, Lord Renning: he cares deeply for her, and wants her to take the throne. The not so good actions that Renning performed as Bertram, one of the Four Riders of Daein, came from him being BrainwashedAndCrazy via a PsychoSerum.]]
** It's subverted in ''VideoGame/FireEmblemFates'': [[spoiler: Azura's mother Queen Arete of Nohr and the Avatar's mother Queen Mikoto of Hoshido are actually good persons... who CameBackWrong thanks to the BigBad Anankos. Even more - Arete battles her niece/nephew, her daughter and their troops ''not knowing who they are'' since she's got LaserGuidedAmnesia. Once either of them is defeated (and in Arete's case, she recovers her memories), they die in peace and speaking to their relatives kindly.]]
* Wilfred Hermeien from ''Videogame/TheLastRemnant''. He is [[spoiler: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.
* ''XWingAlliance'', [[spoiler:Ace's uncle Antan sides with the Empire]].
* [[spoiler:Heiss]] from ''VideoGame/RadiantHistoria'' winds up hitting almost every point in the description. [[spoiler:Jealous, childless younger brother? Check. [[EvilPrince Royalty]]? Check. CainAndAbel? Check. Ex-CoolUncle? Check. Repeatedly tries to kill his niece and sends his nephew out on blatantly impossible missions? Check.]] However, twisting the trope a bit, [[spoiler:he [[LikeASonToMe deeply and genuinely loves his nephew]] and considers himself a StealthMentor. As far as he's concerned his niece can go die in a fire, though]].
* Unavoidable in ''VideoGame/CrusaderKings'', 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.
* ''VideoGame/FarCry4'': 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. [[spoiler:He's not joking.]]
* In ''VideoGame/GranblueFantasy'', [[spoiler:Loki]] is this to Orchis, as it's revealed that he's Orchis' father's brother. He loathes her to the core and wishes to never hear her call him that ever. If the Black Knights's information is to be taken to any hint, it may have to do with him not approving of the marriage of Orchis's parents.
* ''VideoGame/TheWedding'': Uncle Jack, who is the main antagonist of the game. Except that the family didn't know about his insanity or evil deeds, until Anima went into his house and read his diary notes. Said notes indicate that he was taking pills to assume a normal demeanour when in public.
* ''VideoGame/{{Guenevere}}'': Lancelot saves a princess from her Evil Aunt during one of his TimeSkip adventures.
* ''VideoGame/Persona5'': After her mother Wakaba died, Futaba was sent to live with her uncle Youji, whose abuse (he refused to even let her have a bed) led to her present social anxiety issues. After Futaba was HappilyAdopted by Wakaba's friend Soujirou (in exchange for the inheritance fund), Youji began threatening him with trumped-up abuse charges and lawsuits [[spoiler: out of resentment towards his naturally successful sister.]].

[[folder:Visual Novels]]
* Morgan Fey in ''VisualNovel/PhoenixWrightAceAttorney'' is an evil aunt. First she tries to get Maya framed for murder, and then when that doesn't work she outright tries to kill Maya. Note that since Morgan actually ''was'' the older sister and was passed up for the position of Master of Kurain because her spiritual power was weak compared to her younger sister's, this isn't for her ''own'' benefit but rather to install her ChildProdigy daughter, Pearl, as the next Master. ([[StageMom With her controlling the kid, of course]])
* ''VisualNovel/HigurashiWhenTheyCry'': Satoko's uncle Teppei physically abuses her in ''Tatarigoroshi-hen'' and ''Minagoroshi-hen''. Her aunt, Tamae, wasn't very nice either.
* ''VisualNovel/UminekoWhenTheyCry'' has Kasumi Sumadera, an Evil Aunt who's out for revenge against her niece Ange since her mother Kyrie's marriage to Rudolf Ushiromiya ruined her life.
* Crow Harbor from ''VisualNovel/{{Sunrider}}'' was the [[BastardBastard bastard son]] of the Ryuvian [[GodEmperor Infinite Emperor]], and after the Emperor and the crown prince were assassinated by an unknown party (it could have been Crow, it could have been his brother), he plunged the galaxy into a devastating civil war in a bid to put himself on the throne. His niece Sola—who happened to be a [[HeroicBastard bastard herself]]—led the fight against him, and it’s implied that he tried to kill her many times.

[[folder: Web Animation]]
* ''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 ''Webcomic/SomethingPositive'' 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 ''Webcomic/ThistilMistilKistil'', [[http://tmkcomic.depleti.com/comic/ch06-pg21/ Coal's back story has some evil uncles in it.]]
* The trope image is Richard III, as depicted in ''Webcomic/HarkAVagrant'', of whom [[http://en.wikipedia.org/wiki/Princes_in_the_Tower urban legend credits with murdering his two nephews]]. [[SubvertedTrope While a historian in the comic interrupts to point out that many other historical figures had reason for killing the boys]], [[DoubleSubvertedTrope Richard's already killed one]].
-->'''Richard:''' Tell you what -- I'll go halvsies with Buckingham.
* In ''Webcomic/{{Plume}}'', Vesper's narration tries to convince us that Aunt Agatha is an example of this, but she comes across more as strict and demanding rather than evil. Though she does send a bounty hunter after Vesper...

[[folder:Web Original]]
%%* Shin's uncle from ''Literature/SailorNothing''.
* Uncle Lies and Aunt Despair from WebVideo/TheNostalgiaCritic, who were created by Critic to cope with his parents and treat both their children and him awfully. It's also canon that Uncle Lies is WebVideo/AskThatGuyWithTheGlasses back from the dead.

[[folder: Western Animation]]
* {{Inverted|Trope}} in ''WesternAnimation/AvatarTheLastAirbender'', 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 CallingTheOldManOut.
** Interestingly, though, Iroh was originally this while [[WhatCouldHaveBeen the show was still in design]]. Before he was redesigned into the [[TrademarkFavoriteFood tea-loving]], [[SmartPeoplePlayChess Pai Sho playing]] BigFun 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 ''WesternAnimation/TheLegendOfKorra'' with Unalaq, Korra's uncle. Not only does he fix the trial to get his brother Tonraq sent to prison for life, but he also [[spoiler: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 [[BrokenPedestal 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 [[AbusiveParents neglectful father]] to the CreepyTwins Eska and Desna as well, such as leaving an injured Desna on the ground just to try and open the Spirit World portal. [[spoiler:The constrast between Iroh and Unalaq becomes more evident in the episode "A New Spiritual Age", when both appear in diferent moments and interact with Korra.]]
** Then [[spoiler: he fuses with [[UltimateEvil Vaatu]], becoming Korra's EvilCounterpart, the Dark Avatar.]]
* The Shadow Master from the ''WesternAnimation/DoubleDragon'' 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.
* ''WesternAnimation/BikerMiceFromMars'':
** The original 1993 series revealed the main villain Lawrence Lactavius Limburger to be an uncle in the episode "Modo Hangs it Up", although his nephew Marshall is even worse.
** The 2006 revival episode "Swimming with Sharks" introduces Vinnie's maternal aunt Mago, who is a [[SpacePirates space pirate]] who wants to kill Stoker for becoming leader of the Martian freedom fighters instead of her. She also attempts to make a deal with her nephew, Throttle, and Modo to rehydrate Mars by beaming all of Earth's water to the planet, a deal that the Biker Mice obviously refuse.
* A reference in the ''Franchise/MastersOfTheUniverse'' 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 ''[[WesternAnimation/TeenageMutantNinjaTurtles2003 Teenage Mutant Ninja Turtles: Fast Forward]]''.
* Hex in ''WesternAnimation/{{Ben 10}}'' to his DarkMagicalGirl [[DaddysLittleVillain niece]] Charmcaster.
* In ''WesternAnimation/BatmanTheBraveAndTheBold'', 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 ''Series/TheWeirdAlShow'', Fatman had an Evil Uncle Frank who was intended to be a recurring villain.
* In ''WesternAnimation/CodenameKidsNextDoor'', [[spoiler:it turns out that Father (AKA the BigBad) is the uncle of Numbuh 1, as he and Monty Uno (Numbuh 1's father) are brothers.]]
* The Professor is the enemy of WesternAnimation/FelixTheCat. But his nephew Poindexter is friends with Felix.
* ''WesternAnimation/RamboTheForceOfFreedom'':
** "Reign of the Boy King": [[TheEvilPrince 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.
* Series/PunkyBrewster 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.
* ''WesternAnimation/AllHailKingJulien'' 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.
* King Gerard in ''WesternAnimation/TheSmurfs'' has his aunt Imperia and his uncle Sir Leopold, both evil and both desiring to go after their nephew's throne.
* How evil they are may [[DependingOnTheWriter depend on the writer]] but the Ghostly Trio in ''WesternAnimation/CasperTheFriendlyGhost'' are both Casper's uncles (and in some continuities [[{{Nephewism}} guardians]]) and are always portrayed as much meaner than him. Wendy’s witch aunts are the same case with the genders inverted.
* ''WesternAnimation/TimeWarpTrio'' has Mad Jack, twin brother of the main character's Uncle who gave him the book.
* In ''WesternAnimation/StevenUniverse'', though they are unaware of it, [[spoiler:[[BigBadDuumvirate Yellow, Blue, and White Diamond]] are the gem-equivalent of Steven's maternal aunts since Rose Quartz was actually their "sister" Pink Diamond all along.]]
* In ''WesternAnimation/TheCrumpets'', the titular family were frequently swindled by Uncle Hurried and Aunt Harried, who were Pa Crumpet's brother and sister-in-law.
