->''"How is it that the best 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 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 InTheBlood. 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.

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 the StartOfDarkness or FaceHeelTurn. He rarely is a CreepyUncle, though. 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}}.

!!Examples:

[[foldercontrol]]

[[folder:Anime and Manga]]
* 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, especially about his own niece. Unfortunately he didn't account for some tidbits of [[SealedEvilInACan family history]]...
* V.V. of ''Anime/CodeGeass'' is very much an EvilUncle to Lelouch and some of his siblings like Cornelia.
* Rido from ''VampireKnight''.
* ''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.]]
* [[DeadlyDoctor Yashamaru]] from ''Manga/{{Naruto}}'', [[spoiler: or so it seems. He was ordered to pretend to be evil]].
* 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.]]
* While not the hero's Uncle, Joseph Gaul from ''FamiliarOfZero'' is the uncle to a character named Tabitha. He has done some pretty bad things.
[[/folder]]

[[folder:Comic Books]]
* In a short-lived '80s reboot ''Shazam! The New Beginning'', [[{{Shazam}} 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 TheGoldenAgeOfComicBooks, Billy already had an EvilUncle, 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/{{X-Men}}: The Hidden Years'', a series that chronicled early, apocryphal adventures of the original team of ComicBook/{{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.
* [[ComicBook/DisneyDucksComicUniverse Scrooge McDuck]], of all people (ducks), have 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.]]
* 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...
* {{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.
* 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.
[[/folder]]

[[folder:FanFiction]]
* Tabitha's uncle in ''Fanfic/PointsOfFamiliarity'' 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 ''WesternAnimation/AvatarTheLastAirbender'' suggest that Ozai might have had something to do with his nephew Lu Ten's death.
* An 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.]]'
* Scar in [[Fanfic/TheLionKingAdventures The Lion King Adventures]], just as in the film. See below.
[[/folder]]

[[folder:Films -- Animated]]
* Scar from ''Disney/TheLionKing''. He had no official children, but he did choose his successor: Kovu.
* 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.
* Ursula from ''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.
* 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]]

[[folder:Films -- Live-Action]]
* Sir Edgar from ''Film/EllaEnchanted''.
* 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 ''StrangeBrew'', but that's really just because it's a humorous retelling of ''{{Hamlet}}''.
* In ''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.]]
* ''Film/UncleSam'', of course.
* 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 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''.
* ''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. This movie terrified me as a 7-year-old.
* 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.
* 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.
[[/folder]]

[[folder:Folklore]]
* 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 [[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 [[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 NorseMythology, is not Odin's son as in the Marvel version but his foster-brother (a custom of the Norsemen where that 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).
[[/folder]]

[[folder:Literature]]
* Uncle Vernon and Aunt Petunia from ''Franchise/HarryPotter''. Harry's bedroom for the first ten years of his life was the cupboard under the hall stairs. They were child abuse incarnate.
** Subverted since Vernon Dursley is not Harry Potter's blood relative. Harry's aunt, Lily Potter's (neé Evans) sister Petunia Dursley neé Evans doubles as WickedStepmother. [Not to say Vernon were a nice guy, though.]
* 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 inheritence.]]
* Played horiffically straight 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}}''.
* Sometimes played straight, but more often subverted, in ''Literature/{{A Song of Ice and Fire}}'', particularly in the case of King Joffrey. As far as most of the Seven Kingdoms are aware, Joffrey has a whole parade of {{Evil Uncle}}s, including the usurping 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:Stannis isn't really Joffrey's uncle since Joffrey wasn't fathered by Robert, Tyrion actually cares for his nephew, and Jaime is actually Joffrey's ''father''.]] And while none of the three are saints, Joffrey is much more evil than all of them put together, with Jaime even thinking that Joffrey [[spoiler: deserved to die]].
** 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. Their uncle Euron, on the other hand, is a CompleteMonster who 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.
* 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.
* [[spoiler: Goosefeather]] in ''Literature/WarriorCats''. Apparently. The whole scene was somewhat of a MindScrew.
* Judith's uncle Robert de Belleme from ''Literature/TheWildHuntTrilogy''.
* Marina's aunt Arachne in ''[[Literature/ElementalMasters The Gates of Sleep]]'' 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 ''Literature/{{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 so 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.
* ''Kidnappped'' 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 that the opposite was true: Kludd was trying to kill Soren...only to be killed in return by Twilight.
* Beause collectiong 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.
[[/folder]]

[[folder:Live Action TV]]
* Count Dregon was ''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]].
* The second-chance shelter cook was this in the ''{{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'', EmperorCaligula 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.
* 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 ''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.
[[/folder]]

[[folder:Music]]
* There is a German band known as Boehse Onkelz, which translates as... well, you know.
* Music/{{The Who}}'s {{Tommy}}'s Evil Uncle Ernie. When Tommy is ten, his evil Uncle Ernie molests him. When Tommy "wakes up" from his blind, deaf, mute coma-like trance when he's about 18 or 21, Uncle Ernie exploits the "miracle". Then when Tommy becomes a famous pinball player, Uncle Ernie exploits not only Tommy, but his fans, as well.

* 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]].
[[/folder]]

[[folder:Theater]]
* Creator/WilliamShakespeare's ''Theatre/RichardIII'' is the UrExample of this trope - if you feel like discounting all examples from real life that preceded it.
* 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}}''.
* 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}}'' probably counts, 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.
[[/folder]]

[[folder:Video Games]]
* Lord Lundgren, younger brother of Lyndis's grandfather in ''FireEmblem: Rekka no Ken''.
** ''RadiantDawn'' manages to subvert this with [[spoiler: Queen Elincia's uncle, Lord Renning. He cares deeply for her, and wants her to take the throne.]]
** In ''Seisen no Keifu'', Levin has ''two'' of these to contend with, Maios and Daccar. Later on Blume is this to Tinny (though he isn't as cruel to her as [[EvilMatriarch Hilda]] was), and if you pair Lex and Azel with anyone, Danan and Alvis become Evil Uncles to their children.
* 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.

* Another evil aunt: Morgan Fey in ''PhoenixWrightAceAttorney''.
* ''HigurashiNoNakuKoroNi'': Satoko's uncle Teppei physically abuses her in ''Tatarigoroshi-hen'' and ''Minagoroshi-hen''. Her aunt, Tamae, wasn't very nice either.

* 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 points out that many other historical figures had reason for killing the boys]], [[DoubleSubvertedTrope Richard's already killed one]].

* Shin's uncle from ''Literature/SailorNothing''.

[[folder: Western Animation]]
* [[InvertedTrope Inverted]] 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 [[spoiler:Unalaq]], Korra's uncle. Not only does he fix the trial to get 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]] 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.]]
** 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.
* Limburger from ''WesternAnimation/BikerMiceFromMars,'' although his nephew Marshall is even worse.
* 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 ''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 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.
* 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.
