%% One quote is sufficient. Please place additional quotes on the quotes tab.

{{Heroes}} have a Fatal Flaw which they wrestle with on a consistent basis. This may open them up for specific conflicts later -- when a protagonist's fatal flaw is encountered through the course of a plot, the audience's reaction is very tense.

This is not to be confused with what Creator/{{Aristotle}} calls ''hamartia'', also a key part of {{Tragedy}}. A hamartia is a mistake or error a hero makes which leads to his undoing. It is NOT the same as a fatal flaw. This confusion arose from the misunderstanding of Aristotle' Poetics in the 19th Century.

In classic literature, a Fatal Flaw is often what prevents a TragicHero from succeeding, or serves as the cause of their TragicMistake. It is usually some sort of character deficiency listed below or, in conventional television, an addiction of some sort. In modern television, the Fatal Flaw is more likely to lead to a VerySpecialEpisode.

Some specific Fatal Flaws:
* [[AmbitionIsEvil Ambition]]
* [[{{Jerkass}} Cruelty]]
* [[GreenEyedMonster Envy]]
* [[DeliciousDistraction Gluttony]]
* {{Greed}}
* [[{{Hypocrite}} Hypocrisy]]
* {{Lust}}
* [[EvilIsPetty Pettiness]]
* {{Pride}}
* [[ItsAllAboutMe Selfishness]]
* [[ChronicHeroSyndrome Selflessness]]
* [[IneffectualLoner Self-reliance]]
* [[ThePerfectionist Perfectionism]]
* [[HairTriggerTemper Wrath]]
* [[NeverMyFault Blamelessness]]
* [[LazyBum Sloth]]

Note the resemblance to the SevenDeadlySins [[note]](in fact, all of them are in the list above)[[/note]]. Also see VirtueViceCodification for a more comprehensive list of vices identified by various authors throughout history.

If the FatalFlaw doesn't play any role in the story, it's an InformedFlaw. If the flaw isn't quite so fatal, you're likely dealing with MrViceGuy.

A literal fatal flaw, as often seen in science fiction and fantasy, would be PhlebotinumBreakdown and/or AchillesHeel.

[[foldercontrol]]

[[folder:Anime]]
* ''Manga/DGrayMan's'' [[ChivalrousPervert Cross Marian's]] flaw seems to be women and girls. He hates returning to the Dark Order, and has been running from them for 4 years. A team is sent to find him. Chief Komui puts Lenalee, a young girl on Cross' team. Cross ends up back at HQ, but promptly tries to escape. But Lenalee hugged him, and begged him not to leave. He thinks about how cute she is, thus he can't refuse her. And that leads to him attending a meeting, being interrogated for his 4 year absence, investigated, demoted, and put under constant surveillance. His being at the Order in the first place made him easy to find when [[spoiler: someone comes to his room to attempt to assassinate him where upon he's shot in the head.]] The only reason he went through any of that at HQ is because he didn't run away when he had the chance, and the sole reason he didn't is because a cute girl asked him not to leave. And said girl wasn't even one of his lovers.
* Whether it be a raging inferiority complex, self-endangering recklessness, an Oedipus complex, alcoholism, bizarre neo-mystic delusions, or a complete disregard for one's own life, pretty much ''everybody'' in ''Anime/NeonGenesisEvangelion'' had at least one of these. Quite a few have more then one.
* Light Yagami of ''Manga/DeathNote'' has his overwhelming pride, which reaches AGodAmI at its worst and blinds him to the point of refusing to even ''contemplate'' his own failure.
* Lelouch of ''CodeGeass'' does things without considering their negative consequences, keeps too many secrets, and doesn't trust people. His counterpart Suzaku has a large lack of self-worth and is [[WideEyedIdealist too much of an idealist for his own good.]]
** However, Suzaku is unable to see that the people he sucks up to due to his lack of self-worth and desperate desire to be a Britannian are everything that he does not want and he is doing everything he claims he is against on a daily basis.
** [[spoiler:Shirley's]] attraction to Lelouch gets her killed when she confronts Rolo. Even though she doesn't remember him, she trusts him because Lelouch seems to trust him.
* In ''ChronoCrusade'', Chrono's [[OurDemonsAreDifferent demonic instincts]] and [[FailureKnight need to protect others]] (particularly Rosette) sometimes combine to give him a very, very [[UnstoppableRage dangerous temper]]. Since Chrono's powers [[CastFromHitPoints drain Rosette's lifespan]] due to [[DealWithTheDevil their contract]], it's dangerous not just to him, but to Rosette herself. [[spoiler:In fact, in the manga this trope is taken literally, when Aion provokes Chrono into unsealing his powers himself and come at him with everything he's got. Several people are killed in the battle, and it drains so much of Rosette's life that the next time she unseals the watch, she dies.]]
* Death the Kid from ''SoulEater'' has his [[SuperOCD raging OCD]] and self-esteem issues; the presence or lack of symmetry in his surroundings (or remembering that he may have forgotten to symmetrically fold his toilet paper roll this morning) can take him out of a battle in a heartbeat.
** In one case, Liz actually uses this against him to avoid getting into a battle in the first place, as the factory containing the Clown scared her, (and with good reason). She does something similar earlier, when taking note of Free's ball and chain to provoke Kid to attack the werewolf.
** The Salvage arc suggests that potentially each of the Great Old Ones has one of these which would make Beat Them By Compulsion a valid tactic against Physical Gods.
* The main characters of ''DGrayMan'' have this. Allen [[ChronicHeroSyndrome goes out of his way to save others]], even when it's [[HonorBeforeReason impossible for him to do so]]. Kanda is [[GoodIsNotNice extremely arrogant and rude to the people he has to work with]]. Lenalee has a raging fear of losing anyone close to her. Krory is a HorribleJudgeOfCharacter. Miranda has next to no self-esteem and is [[TheEeyore easily depressed]]. And Lavi is torn between his duty as a Bookman and the people he cares about.
* ''Anime/YuGiOhGX'': Juudai's stubbornness, being headstrong, irresponsible, impulsive, and impatience are cute and endearing for two and a half seasons. Then all of those combine and (he thinks) gets four to five of his best friends killed.
* From ''{{Durarara}}'', Shizuo's severe anger issues and Kida's inability to face [[MyGreatestFailure his guilt head on.]] Not only does this put him in a position where he avoids his girlfriend Saki [[spoiler: they make up at the end of the anime series]] but by not facing this head on, [[spoiler: he repeats his whole guilt trip with his best friend Mikado by dropping out of school and leaving Ikebukuro. And Mikado didn't take this well...]]
* ''TengenToppaGurrenLagann'': Kamina's impatience, Simon's lack of faith in himself. (Of course, Simon beat his fatal flaw senseless about halfway along and went on to use its limp form as a club, but that's not important right now.)
** Kittan's inferiority complex led to his CrowningMomentOfAwesome when he [[spoiler:stole a kamikaze attack Yoko was about to volunteer for.]]
* [[EvilMatriarch Precia Testarossa]]'s HeelRealization in ''MagicalGirlLyricalNanoha TheMovie 1st'': [[RememberedTooLate "I never notice things before it's too late."]]
** Similar with Light Yagami above, Cypha in ''Manga/MagicalRecordLyricalNanohaForce'' so ''prideful'', that her pride blindsides her and causes her to ''severely'' underestimate things.
* The characters in ''Anime/PuellaMagiMadokaMagica'' had their downfall brought by their respective FatalFlaw. Sayaka's is {{Pride}}, Mami's is Loneliness, Madoka's is Self''less''ness, and Homura's is Ambition. And QB is thwarted thanks to his Lack of Emotion. Kyouko however, only died ''after'' she set aside her Selfishness. DeathByIrony?
** Then, clearly shown in Rebellion, Kyubey's is {{Greed}}.
* In ''TigerAndBunny'', Kotetsu has a noted tendency to [[CannotSpitItOut keep personal struggles to himself]], even when those personal issues don't just affect him. This starts really coming down hard on him in the second half of the series [[spoiler:when he can't work up the nerve to tell Barnaby he's retiring, or [[DePower the reasons]] behind it, and Barnaby takes it as a sign that he doesn't trust him]].
** And Barnaby has his own flaw; the hell-bent obsession with revenge that made him an IneffectualLoner who has rejected any close personal relationships for the past ''20 years''.
* According to Shura of Manga/BlueExorcist, Yukio could be exploited by demons because he keeps his emotions bottled up unlike his more hot-headed brother Rin. Likewise, Rin has trouble controlling his flames because he's afraid of them.
* SchoolRumble
** Harima is so [[LoveMakesYouStupid committed to making Tenma happy]] that he's willing to deprive himself of happiness.
** Tenma always wants to make others feel better. This almost get her killed in the manga.
** Eri is a ClingyJealousGirl. A ''hint'' of Harima getting paired with a girl sends her into a quiet rage which almost messed up her friendships with Mikoto and Tenma, and in the manga [[spoiler:almost gets Tenma killed]].
* Future Trunks from ''DragonBall Z'' at first appears to have everything together: is a BadAss, has a tragic past, able to beat Freeza and King Cold like it was nothing. But as the arcs progress, his fatal flaw regarding [[WellDoneSonGuy his issues with Vegeta]] end up costing him big.
** Vegeta himself allows his stubborn pride and arrogance to get the better of him several times.
** Goku has one that rears its head on occassion: His love for a challenging battle. He projects this desire onto Gohan, who lacks said love, leading to Goku's death.
** Most of the villains in fact have the fatal flaw of thinking there is no way they can be defeated. With Vegeta, it was a low-born defeating an elite. Freeza couldn't comprehend (or rather refused to accept) that a "[[FantasticRacism monkey]]" could become stronger than him. Cell believes his final form is perfect (having the best qualities of each fighter) and thus cannot be defeated. Buu couldn't stand Vegetto's strength. All of them suffer a VillainousBreakdown when they are proved wrong.
* In ''{{Bakuman}}'', Nanamine's fatal flaw is his inability to empathize with others. Not only does it lead him to [[spoiler:twice attempt to rise to the top of Jump by using consultants, all the while viewing people as expendable]], but it also means he is unable to write characters with "heart", in spite of his talent as an artist.
* {{Berserk}} has Guts' [[UnstoppableRage wrath]] and Griffith's [[AmbitionIsEvil ambition]] and {{pride}}. One could make the case for {{lust}} in Griffith's case considering that it was sleeping with the Princess that directly caused his downfall, although that seemed to be more about wounded pride than sex ''per se''.
* In ''Manga/AttackOnTitan'', Eren is very emotionally-driven (especially by [[HotBlooded his]] [[TheBerserker temper]]) and can be reckless at times, which tend to him making decisions that end up having negative consequences for himself and others. Such as trying to avenge Thomas's death, [[spoiler:resulting in most of his team's deaths and himself being eaten]].
** Mikasa's protectiveness over Eren had her prioritizing his safety over everything else, including her own life, which clouded her judgement and made her less efficient as a soldier. When [[spoiler: she thinks Eren died in Trost]] and again when [[spoiler: the Female Titan captured Eren]], she became recklessly suicidal and at one point, it led to [[spoiler: Levi being injured to save her.]]
* Luffy's wrath and selfishness in ''Manga/OnePiece''. His inability to control his volcanic-rage eventually lead to [[spoiler:Kuma attacking and scattering all the Straw Hats around the world.]] Luffy does what he wants, even if he knows there would be grave results. The above example had Hatchan making Luffy promise not to [[spoiler:cross paths with a World Noble, regardless what happens.]] But when [[spoiler:Camie and Hatchan]] are kidnapped and injured, Luffy went ahead and broke his promise and while he did apologize, he didn't show any regrets.
* In ''Manga/{{Bleach}}'', Aizen's god-complex and belief that he was above everyone else led him to discard strategy and cunningness (what had previously allowed him to outsmart and outplay his enemies). He relied too much on his unnatural power upgrades and became DrunkWithPower. Which would lead to [[spoiler:his defeat at the hands of both Ichigo and Urahara.]]
* It becomes clear pretty quickly that Satou's biggest flaw ({{Hikikomori}} tendencies aside) in ''WelcomeToTheNHK'' is his incredibly addictive personality, marked by him hurling himself headlong into anything he's introduced to (internet porn, {{MMORPG}}s, etc.) and needing to be bailed out by others.
[[/folder]]

[[folder:Comic Books]]
* [[TeamMom Nico]], leader of the ''ComicBook/{{Runaways}}'', is an interesting take on Lust as a flaw. She's quite responsible in most ways, but when dealing with stress or trauma, she (in Nico's own words) 'throws herself at the nearest warm body'. This habit doesn't cause Nico's downfall, but it frays her self-esteem and sabotages her friendships.

[[/folder]]

[[folder:Fan Fiction]]
* In the ''Franchise/DotHack'' fanfiction [[http://www.fanfiction.net/s/4036084/1/ .hack//G.U.: The Staircase to Nowhere]], each of the Epitaph users has one physical/mental flaw that can spell the end for them in the Goddess Morganna's war; Haseo has his photophobia (his sensitivity to light), Atoli's fear of being alone, Endrance's weak lungs, and Kuhn's color blindness.
* In the {{Glee}} fanfic ''Fanfic/HuntingTheUnicorn'', Blaine's [[WideEyedIdealist Wide-Eyed Idealism]] has gotten him [[TrueCompanions the Warblers]], [[OfficialCouple Kurt,]] an [[UnluckyChildhoodFriend unlucky high school friend,]] [[ParentalNeglect an emotionally estranged father,]] and [[spoiler: ''a stalker'']]. Not to mention that [[spoiler: he lost his virginity to a guy who did ''not'' share his belief that SexEqualsLove.]]
* ''FanFic/GettingBackOnYourHooves'': [[BigBad Checker Monarch]] is a [[TheChessmaster master manipulator]], but her plans ultimately fall apart because of her [[EvilCannotComprehendGood inability to understand empathy]].
* ''FanFic/MassEffectTheEquestrianEquation'': The Equines were naturally trusting and cooperative, causing Reaper Indoctrination to wreck their defenses and cost them the war.
* In Fanfic/RainbowDoubleDashsLunaverse, Luna's is irrational fear, mainly of becoming a tyrant, which prevents her from taking decisive action against the DeadlyDecadentCourt.
* In ''Fanfic/TheIronyOfApplejack'', [[BigBad Vigil]]'s is the fact that he's [[ThePerfectionist obsessed with perfection]].
[[/folder]]

[[folder:Film]]
* ''Film/BackToTheFuture'''s Marty [=McFly=] and his compulsion to prove that he's not "chicken". This is eventually stamped out through CharacterDevelopment.
* ''PlunkettAndMacleane'''s main character Macleane has a weakness for women and gambling. Both get him into serious trouble.
* In the ''StarWars'' prequels, Anakin Skywalker's fatal flaw is his arrogant insistence that he can do anything, ironically causing him to turn to TheDarkSide in his narrow-minded effort to [[AlwaysSaveTheGirl save Padmé]] [[MoralEventHorizon at all costs]].
* ''CarlitosWay'' has a variation of this trope. Carlito's Fatal Flaw is either his determination to keep his "reformed" status, or his ties to his criminal past. If he had gotten rid of one of the two, there might have been a happy ending.
** Actually, his fatal flaw was his belief that there was honor among thieves and street code you follow. It's how he went to prison in the first place, taking the rap for the guy that would take over his territory. It's also how he ended up in a bad spot[[spoiler: helping his best friend who turns out to be a snake. The scene when his girlfriend begs him not to help the lawyer is proof of that. Worst of all, he gets a good example and even admits there's no true friends among criminals, when his young relative gets killed in the beginning of the film. But you can't teach an old dog new tricks.]]
* [[{{Saw}} Jigsaw]]'s MO is setting people up in traps (or as he calls them, tests and "games") where someone must overcome their FatalFlaw or be destroyed. Seriously.
** Nine times out of ten, they lose.
* ''Film/FullMetalJacket'''s Sgt. Hartman's inability to deal with issues without using force.
* ''Film/StarTrekIITheWrathOfKhan''
** Khan's obsession with taking his vengeance on Captain Kirk blinds him to some very bad mistakes and ultimately destroys him.
** Kirk's hubris; his unshakable belief in his own ingenuity and command instincts. Therefore he's taken off guard by something that even raw cadet Saavik saw coming. And he arrogantly believes there's no such thing as a situation that he can't win. As his character develops throughout the film, he learns just how misguided he's been.
* [[TheGodfather The Corleone Brothers]] all inherited a trait from their father (Sonny's charisma, Fredo's heart and Michael's cunning) which they don't have in each other. Had they worked together, they would have been unstoppable.
* In ''Film/TheHobbit'', Thorin's biggest flaw is his pride, as lampshaded by Gandalf.
** His grandfather Thrór became so greedy and obsessed in filling his halls with gold that it would attract Smaug and eventually led to the downfall of Erebor.
* Daniel Plainview from ''Film/ThereWillBeBlood'' thrives on animosity and he goes after enemies with a will. He ends up driving away the boy who he treated as his son and kills his arch-enemy without thought of consequence.
* CLU in ''Film/TronLegacy'' suffers from an unquenchable need for perfection. He inherited this from Kevin Flynn when he was programmed, but unlike Flynn he is a program and is unable to learn from his mistakes.
* Dr. Elsa Schneider in IndianaJonesAndTheLastCrusade suffers from multiple flaws: ambition, greed, and vanity. Her ambition to get the holy grail at all costs turns fatal when she's faced with the decision to reach for the grail or give Indy her free hand. Overcome with greed, she reaches and cannot stop herself. Indiana can't hold her because, in her vanity, she wore fancy leather gloves on her hands, which promptly slips off. All these flaws contribute to her long plunge of a DeathByMaterialism.
* ''Film/AnchormanTheLegendOfRonBurgundy''. Ron always reads what's on the teleprompter.
* Rocky from ''Film/AngelsWithDirtyFaces'' is loyal to a fault.
* Tommy DeVito and his HairTriggerTemper in ''Film/GoodFellas'' where he killed a made man lead him to be killed himself.
[[/folder]]

[[folder:Literature]]
* ''Literature/ASongOfIceAndFire'' could fairly be described as a dozen or so tragedies going on simultaneously (with several in the backstory). This implies almost every single character having their own fatal flaws.
** A common flaw in the Starks is HonorBeforeReason (which could be seen as a form of {{pride}}), especially in Eddard and Robb.
** Stannis shares much of the same HonorBeforeReason attitude initially, although [[CharacterizationMarchesOn in later books he is more willing to compromise.]]
** [[AdiposeRex Robert Baratheon]]'s is gluttony.
** The Lannisters lean toward {{pride}} with a side of wrath: see Tywin, Cersei, and Joffrey. A big part of Tyrion and especially Jaime's character development is overcoming this.
** Theon's could be considered [[AmbitionIsEvil ambition]] with a side of {{pride}}. He gets both [[BreakTheHaughty beaten out of him]] by [[HumiliationConga hard experience]].
* Hubris is a common tragic flaw in mythology and classical literature. One of the more famous examples is Odysseus, who is forced to undergo a 10-year voyage home after angering Poseidon with his arrogance.
* ''ThePillarsOfTheEarth'': Not a hero, but William is absolutely terrified of a FireAndBrimstoneHell. It's a flaw because others use it to exploit him and make him do their bidding.
* In ''Literature/PercyJacksonAndTheOlympians'', it's explicitly stated that every demigod has a FatalFlaw which, if not mastered, will lead to their death. Annabeth's fatal flaw is explicitly stated to be hubris (except Percy thinks she says hummus). Percy's is personal loyalty--he will do anything necessary to save the people he cares about, even if that means ignoring the greater good. Thalia's fatal flaw is that she has a weak resistance to offers of power, to the point she seriously considered betraying her friend to become more powerful than the gods (though her conflicting feelings over this were apparent). It's a good thing Mr.D was able to step in otherwise she probably would have given in. [[spoiler:Nico and Bianca]] have the FatalFlaw of holding grudges, which they inherited from their father.
* In ''Literature/TheDresdenFiles'', Harry saves people. [[ChronicHeroSyndrome It's just what he does.]] At one point, someone immediately figures out that he's harboring a fugitive because that's Harry's schtick; people come to him for help, [[WeHelpTheHelpless he helps them]]. Even if the person is someone he doesn't like, he will help them.
** In the Backup Novella a "[[FemmeFatal client]]" deliberately plays the part of damsel in distress complete with kidnapped child to get Harry's help as part of her plan, Thomas steps in without Harry knowing to save him.
** His other fatal flaw is probably his temper. When he gets mad enough, he'll do almost everything in his power to destroy the bad guys with little regard for the consequences. He reevaluates this outlook in "Ghost Story", after [[spoiler: the destruction of the Red Court throws the world into chaos.]]
* ''Literature/HarryPotter'''s [[ChronicHeroSyndrome "saving people thing"]] gets him into trouble. He's willing to do anything in order to save the people he cares about, and he has a martyr complex that keeps him from asking for help or back-up at times when it would really be a smart idea. He does this to keep the people around him safe but it tends to really work against him. [[spoiler: Voldemort uses this to manipulate him into doing things that lead to Sirius's death.]] This also makes it very easy for Harry's enemies to lead him into traps.
** Voldemort's fatal flaws:
*** {{Pride}}. It's not so much petty, plain-old narcissism and arrogance than it is outright full-blown megalomania. He's the smartest and most powerful wizard in the world and he knows it, so he tends to go out of his way to add a flair of grandeur and grace to his plans while attempting to achieve his objectives in the way he thinks will be more terrifying. For example, he challenges Harry to a duel in the graveyard sheerly for amusement, when the most pragmatic option would be to simply give the ''Avada Kedavra'' right there and then when Harry was tied up and couldn't escape. Thus, he doesn't realise that other people could learn about his Horcruxes, or find them, and he certainly doesn't realise that attempting to kill the boy destined to defeat you may result in that boy being actually able to defeat you. And thus, Harry Potter was given the weapons to destroy Voldemort.
*** Voldemort also cannot understand [[ThePowerOfLove love]], though he can't help that - he's TheSociopath whose complete incapability for love and compassion were caused by the fact that his mother coerced his father into marriage with a love potion, which is not true love.
*** Voldemort is also so terrified of death -- WordOfGod states that Voldemort's boggart would look like his own corpse -- that he doesn't believe that there could be anything worse. His quest to cheat death forever, combined with his other fatal flaws mentioned above, ultimately condemns him to a FateWorseThanDeath.
** Sirius's recklessness; he's a LeeroyJenkins.
** Severus Snape hangs on to the past to the point that he makes seemingly irrational choices simply because of some event or another that happened a long time ago.
** When he was young, Dumbledore had a whopping case of {{Pride}}, [[spoiler: planning to create a "new world" with [[ThoseWackyNazis Grindelwald]] in which wizards would rule over muggles.]] He snapped out of it [[spoiler: with the death of his sister]] and spent more than a century deliberately avoiding powerful positions because he didn't trust himself. He refused the position of Minister of Magic, for instance.
* Heathcliff of ''Literature/WutheringHeights'' holds on to grudges and he spends his life getting even with people who were mean to him. He uses his own family as pawns and holds Kathy on such a high pedestal that he refuses to see that everything that happened to him was her fault. He is also blind him to the fact that his revenge can never last so when he dies and everything reverts back to normal, it's like nothing happened.
* Ahab's self-destructive quest against MobyDick.
* Ambrosio, titular character of ''Literature/TheMonk'', commits the sin of {{pride}} long before he starts committing any of his truly deplorable acts. It is his pride that allows him to believe himself holy while he continues to sin.
* [[Literature/TheIliad The Trojan Royal Family]] is so tight that they protect Paris even though they know he is wrong for taking Helen with him. [[TheTrojanWar This dooms them and their country]].
* The animals of ''Literature/AnimalFarm'' were far too [[DumbIsGood trusting]]. Benjamin the donkey is too cynical and refuses to voice out his concerns about the Rebellion's aftermath.
* Gollum's obsession with [[ArtifactOfDoom the Ring]] in ''Literature/LordOfTheRings''.
* ''Literature/TheBible''
** ''Literature/BookOfGenesis'' - Adam's ignorance, Eve's greed, Cain's anger, Abel's self-righteousness, Abraham & Sarah's desire to have a child and Joseph's pride.
** ''Literature/BookOfExodus'' - Moses' anger. Aaron's weak leadership. Miriam's jealousy of Moses. Balaam continuing to antagonize the Israelites even after experiencing God's power.
** ''Literature/BookOfJudges'' - Jephthah's rashness. Samson's lust for women and drink.
** ''Literature/BooksOfSamuel'' - Saul's tendency to follow his own way rather than waiting for a command from God. David's inability to control his children . Joab's violence.
** ''Literature/BooksOfKings'' - Solomon's [[LonelyAtTheTop dissatisfaction with his life]]. Ahab's inability to stand up to his wife.
** ''Literature/BookOfEsther'' - Haman doesn't understand that he's just a despot's favorite. He can be replaced at a whim.
* ''Literature/TheApprenticeRogue'': [[spoiler: Falita is consumed by her greed and steals Leona's necklace, which leads to tragedy. She even takes the hemp string on the necklace, despite recognizing that it was worthless, because it was part of the necklace. The narration notes that she might have gotten away clean if she didn't take the string.]]
* Jay in the ''Literature/{{Spaceforce}}'' series is a highly competent agent for the Taysan Empire, fearless, clever and resourceful, with a talent for deception and masquerade that is highly unusual in his species. But he is constantly undermined by his compulsive womanising, which has brought him to the brink of disaster at least twice. It's all the more dangerous because sexual immorality is actually a crime in his society.
* ''Literature/TheGreatGatsby'''s obsessive love for Daisy, [[LovingAShadow despite the fact she isn't worth it]]
* In the ''Samurai Kids'' book ''Monkey Fist,'' [[TheHero Niya's]] flaw is loyalty- he will not abandon a friend for any reason. While this may sound like a good thing, it really isn't. In the novel's climax, Niya's [[TrueCompanion true companion]], Kyoko, has been kidnapped by a [[CorruptCorporateExecutive corrupt imperial minister]], who offers to release her if the protagonists reveal the location of a group of benevolent monks politically opposed to him. Niya's thought process clearly shows that, had the choice been his, he would have betrayed the monks and let them die if it meant Kyoko's safety.
* In ''Literature/ThingsFallApart'', Okonkwo's flaw is his pride. His dad was a lazy deadbeat, and he's afraid of other people thinking that he's like that too. The author Achebe modeled Okonkwo after the heroes of Greek {{Tragedy}}, so it's no surprise that his flaw is hubris, leading to the atë (rashness) that caused his downfall.
* The titular ''Literature/{{Julian}}'' has a deep craving for the mystical and incomprehensible. Relying on the insights of a [[LargeHam hammy]] soothsayer isn't wise, especially when you're the Emperor of Rome.
* Most of [[QuirkyMinibossSquad the Forsaken]] from ''Literature/TheWheelOfTime'' have at least one which is responsible for their descent into villainy. Most obviously, Be'lal's flaw was Envy of everyone and everything more powerful than he was (he was even known as "The Envious"), and Demandred's was the combination of Wrath and Pride that lead him to hold a vengeful grudge against [[TheChosenOne Lews Therin Telamon]] beyond all reason.

** Abed's LackOfEmpathy.
** Pierce's BrutalHonesty.
* Lord Grantham from ''Series/DowntonAbbey'' is a BenevolentBoss to his servants but this doesn't stop him from thinking them inferior and preferring the company and advice of his "peers". This haunts him when bad advice from an aristocrat doctor over that of their regular physician Dr. Clarkson [[spoiler:causes the death of his daughter Sybil]].
* ''HomicideLifeOnTheStreet'' - Frank Pembleton's self-righteousness and moral absolutism drive everyone away from him, and eventually [[spoiler: force him to turn in Tim Bayliss, the closest thing he has to friend.]]

** Victor Drazen putting RevengeBeforeReason.
* ''Series/BreakingBad'' - [[AntiHero Walter White's]] {{Pride}} causes him to start cooking meth instead of accepting charity in the first place, and continues to get him into escalating trouble from there, eventually turning him into a full-fledged VillainProtagonist.
** Gus Fring's determination to get revenge [[spoiler: against the men who killed his best friend is another major example. He even had a chance to avoid his death by letting his [[TheDragon dragon]] kill the main object of his hate. But because he had to do it, personally, he walked right into a death trap.]]
* In ''{{CSI}}'':
** Warrick's gambling problem.
** Ray's struggle to avoid giving into the violent tendencies he feared he'd got from his father.
* In ''{{Cheers}}'', Sam Malone's former drinking problem.
* In ''Series/{{Smallville}}'':
** Clark's is his lack of self-worth. Or alternatively his [[{{Hypocrite}} hypocrisy]] about keeping secrets to his friends, which [[CloningBlues Major Zod]] would call him out on.
** [[LexLuthor Lex's]] is his [[GreenEyedMonster envy]] of Clark's life: which gave him a loving family, was well-liked and was special; whereas Lex was a LonelyRichKid whose father was [[AbusiveParents cold]] [[ManipulativeBastard and manipulative]] with a MissingMom [[BrokenPedestal who's worse than]] [[AbusiveParents he'd like to imagine]]. Which set him [[FaceHeelTurn on the path to villainy]].
** Chloe's was [[GreenEyedMonster jealousy]] which worked to [[MagnificentBastard Lionel Luthor's]] advantage; but later became {{Pride}}, apparently.
** [[GreenArrow Oliver's]] is his lack of self-worth, which later led to [[DrivenToSuicide a suicide attempt]], and [[GodOfEvil Darkseid]] [[DemonicPossession influencing him]].
* Series/{{House}}'s vicodin addiction, irritability, and inability to have a healthy relationship.
* In ''TheJohnLarroquetteShow'', John Hemingway's (recovering) alcoholism.
* ''Series/BabylonFive'' had Dr. Franklin addicted to "stims" for most of one season, and battling his addiction for a second; and Security Chief Garibaldi's alcoholism (which he had successfully battled for most of the show's run) formed a major part of the fifth season's arc.
* ''Series/LawAndOrder'': Most characters from the franchise have one of these that occasionally clouds their ability to do their job ethically and fairly or discredits their testimony once in court. Briscoe had drinking problems, Logan was a hothead who'd occasionally [[RabidCop rough up suspects]], Curtis couldn't curb his infidelity, and so on.
** The same with ''Series/LawAndOrderSpecialVictimsUnit''. Olivia and her belief all women are victims when it comes to dealing with men, [[spoiler: given that she was a product of rape.]] Fin and the revelation that he was a deadbeat father. Elliot and his marital problems at home.
* Most of the cast of ''What Its Like Being Alone'', including Armie, who only has one limb left, Aldous the EmoTeen, Princess Lucy, who would be the AlphaBitch if she weren't fiendishly ugly, Sammie the alcoholic FishPerson, Charlie, who is always on fire, Seymour, who doesn't have a mouth, and other unfortunates. They're also all orphans.
* ''Series/{{Heroes}}'': Pretty much every character on the show has a fatal flaw (drug addiction, insecurity, tendency to explode, [[GoodThingYouCanHeal carelessness]].
* ''Series/{{Supernatural}}'': Dean for Sam, Sam for Dean and both of them for John while he was still alive. Ah, the joys of being a [[ThickerThanWater clingy]], [[DysfunctionalFamily screwed-up family]] filled with [[MartyrWithoutACause martyrs]].
** Both brothers have no sense of self-worth thanks to [[ParentalNeglect Dad]], who refuses to show any affection or let anyone help him, preferring to keep his sons completely in the dark. Not the greatest planner with [[CrusadingWidower vengeance on his mind]], this works out badly.
** Dean's self-loathing. His struggle to hold his broken family together, along with his sluttiness, death-wish, general bone-headedness, and feeling that he's only valuable as a "blunt instrument", all seem to stem from efforts to ''do'' enough that he feels worthwhile.
** Sam's insecurity. His [[HorribleJudgeOfCharacter gullibility]] and [[TheOnlyOne pride]] seem to be born of his overriding desire to believe that bad people can be good--that ''he'' can be good.
* Many of the characters in ''{{ER}}'' have one at some point or another. Examples include Abby's alcoholism, and Carter's painkiller addiction.
* On ''AmericanGothic'', Dr. Crower's fatal flaw would quite obviously have to be his struggle with alcoholism (and [[{{Backstory}} the tragic event which resulted from it]]). Gail's, apparently, is [[EvilIsSexy sex]].
* In ''Series/{{Scrubs}}'', the character Dr. Kevin Casey is an example of TheAce with a hidden FatalFlaw. JD, Cox and Turk all despise him for being such an insufferable genius at everything he does. Until they see him suffering because of his obsessive-compulsive disorder, unable to stop washing his hands.
* Team leader Nate's alcoholism in ''Series/{{Leverage}}'', which has gotten the team into trouble more than once. In the periods where he isn't an alcoholic his desire to control takes its place with often worse problems.
** Sophie, the team grifter, has the flaw that she is extremely good at what she does and has the habit of manipulating everyone around her, even her own team at times.
** Hardison has the flaw that he tends to go over the top as a grifter coupled with a heaping of pride in his own intelligence. This gets him into trouble repeatedly.
** Parker has the flaw that she is incapable of dealing with a normal person which is problematic when she is forced into the role of grifter.
** Eliot? Let's just say that he often gets a little carried away as The Hitter.
* In ''Literature/TheChosen'', Rebbe Saunders' near-fatal flaw was fear that his son would be unworthy. It is overcome because Danny loves his father enough to endure the harsh training that his father thinks he needs.
* In the 1998 ''Film/{{Merlin}}'' series, the titular character's fatal flaw is that he sees only the good in people, rather than their flaws, and thus expects too much of men. The villains also have their own fatal flaws, with Vortigern's being his {{Pride}}, and Uther's being {{Lust}}.
* In ''Series/TheVampireDiaries'', Damon's impulsiveness, and Stefan's inability to control his addiction to human blood whenever he has even a little.
* ''TheWire'', most of the characters are flawed in their own way, but the most obvious example, would be Jimmy Mcnulty. Ironically, his whoring and drinking don't affect his work but rather his personal life to the point where he becomes a burden to those around him.
** He can't be a good detective and a good person at the same time. Eventually, that leads to him doing wrong things in order to make the right case, which doesn't end well.
* Wesley from ''Series/{{Angel}}'' has a tendency to commit rash action usually for a good reason. It comes back to haunt him in seasons 3-4. Wesley also has a mistrust of others and compulsively hoards every secret to himself.
* Shinya Arino of ''RetroGameMaster''/''Gamecenter CX'' has major problems when it comes to certain gameplay twists, most notably when dealing with a SequentialBoss. Whenever he makes a major accomplishment, he starts cheering and lets go of the controller. The problem is that he plays games ''blind.'' Thus, he doesn't realize it's not over, yet he never seems to learn. It's been called "Heaven to Hell" on a few occassions. By the time he realizes what's going on, he's to shocked to rationally continue and dies. Sometimes he recovers and retries, sometimes he doesn't, most notably with [[spoiler: ''Act Raiser'']].
* ''XenaWarriorPrincess'' is all too willing to give up her life to save others.
** Gabrielle's strict adherence to ThouShaltNotKill.
** Joxer wanting to prove he can fight.
* ''Series/BuffyTheVampireSlayer'':
** Buffy and all her predecessors are implied to get too careless after a while, leading them to get killed before their time.
** Pride seems to be a popular one.
* A few in ''Series/OnceUponATime'':
** Rumpelstiltskin is a coward. This leads him to become the most powerful magical entity in his world to make up for it [[spoiler:and find his son]].
** August is ''really'' bad at resisting temptation. At the start of the series, he was off at some resort island [[spoiler:using money he was supposed to send to Emma]].
** Regina is ''completely'' GenreBlind and very emotional, which results in her being led around by the nose by Rumpelstiltskin.
* ''Series/{{Nikita}}'' is too secretive, stemming from her inability to trust.
** Alex is naive and vengeful and is turned into Oversight's pawn.
** Michael puts himself in danger for the women he loves.
* ''Series/BurnNotice''
** Michael's {{Determinator}} quality makes him utterly ruthless and willing to put others in danger.
** Sam would put himself in danger for friends. "I owe him" is his unofficial motto.
** Fiona resorts to violence more times than she should.
** Nate's need to prove that he's reliable and not a screw up.
* Both Ross and Rachel in ''Series/{{Friends}}'' suffer from NeverMyFault, most likely stemming from when their parents spoiled them as children. This leads to their breakup since a major reason why their relationship failed is because both of them don't take responsibility for anything and are quick to blame others and each other for their mistakes.
** Chandler also suffered from deep self-esteem issues that inhibited his ability to engage in long-term relationships. Much of this is due to FreudianExcuse. His parents' acrimonious divorce was so traumatizing that it left him hesitant to commit out of fear of screwing things up. Exacerbating the matter was the fact that his two initial recurring love interests (Janice and Kathy) ended up cheating on him when their respective relationships became difficult to maintain. Thankfully, in Season 5, Chandler hooks up with Monica, someone who could share the feeling of suffering from emotionally AbusiveParents throughout childhood and who had worked through self-esteem issues of her own. Together, the two are able to build a relationship based on trust and mutual understanding, allowing for a [[HappilyMarried happy marriage]] that lasted throughout the end of the series.

[[folder:Professional Wrestling]]
* Wrestling/DolphZiggler is too HotBlooded and easily frustrated by failure.
* Wrestling/CMPunk's fatal flaws are arguably his arrogance and tendancy to blame everyone but himself.
* [[Wrestling/BryanDanielson Daniel Bryan]]'s fatal flaw is his egomaniacism.
* Vanity is Wrestling/CodyRhodes fatal flaw.
* Wrestling/{{Raven}}'s is his selfishness; one of his catchphrases is even "What about ''me''? What about ''Raven''?"
* Many times HonorBeforeReason has kept Wrestling/JohnCena from winning.
* Lucha wrestler's attachment to their masks is SeriousBusiness.
* Wrestling/{{Edge}}'s fatal flaws were his overconfidence and HairTriggerTemper.
[[/folder]]

[[folder:Tabletop Games]]
* In the system called ''House of the Blooded'', the characters are all nobility, seemingly built for high drama and Mary/Marty Sue-ism. Each character has six characteristics, each based off of one of the major families, and there is no rolling involved. You have four points for one characteristic, three for two others, two for two more... and the sixth characteristic gets a ''zero'', meaning you can never use it. A zero in Strength means you are too physically weak to force open a sticky door, for example, thus ensuring that ''all'' characters have an inbuilt FatalFlaw that cannot be legally circumvented.
* In ''TabletopGame/{{Traveller}}'' the FatalFlaw of the Vilani was in trying to call a halt to progress for the sake of stability. Which worked so long as they did not find an outside competitor(I.E. Earth) The FatalFlaw of the Terrans was more complex. It was in trying to govern the thousands of conquered Vilani worlds without the experience or inclination. The Vilani system was too repressive for the Terrans to use it and the Terran system was only suited for governing a few dozen worlds.
* This trope is present (and ''of course'' taken UpToEleven) in ''TabletopGame/{{Exalted}}'':
** The Solars, Lunars, Dragon-Blooded and Sidereals all get various versions of the Great Curse, a psychological affliction thrown at them by the Primordials for besting them in war. The Solars and Lunars enter a brief psychotic period called a LimitBreak (ranging from berserker rage[[note]] Berserk Anger.[[/note]] to uncontrolled crying at the suffering of the world[[note]] Heart Of Tears.[[/note]] to becoming cold and uncaring about the suffering of others[[note]]Heart Of Flint.[[/note]] to despising others' faults[[note]] Contempt Of the Virtuous.[[/note]] and well... being a jerkass[[note]] Deliberate Cruelty.[[/note]]), the Dragon-Blooded get a lighter version of the same, and the Sidereals [[ASimplePlan can't seem to make any of their big plans work right]].
** The Abyssals, on the other hand, get Resonance. If, for some reason, they decide they don't want to go along with their masters' goals of [[OmnicidalManiac feeding all Creation into the mouth of Oblivion]] and resume something approaching a mortal life, their Resonance will build until it erupts and risks destroying any emotional connections they've managed to make with the world of the living.
** The Infernals get a similar variant, known as Torment. If they defy the will of their [[OurDemonsAreDifferent Yozi patrons]] for too long, then said patron will assume control and cause shit to go haywire. This can range from spreading a HatePlague (Malfeas) to [[WalkingWasteland causing the immediate vicinity to become a lifeless and spiritual wasteland]] (Cecylene).
** Even without supernatural curses or compulsions, each of the four virtues has drawbacks if you have three or more dots (and exalts have to have at least one virtue of 3+): compassionate characters have trouble making harsh decisions; temperate characters have trouble lying, cheating or going back on their word, no matter how dishonest the antagonist; valorous characters don't know how to back down from confrontation; and as for conviction, [[KnightTemplar well]]... Oh and it's perfectly possible for a character to have 3+ in two or more virtues. If they conflict, tough luck!
* WhiteWolf are generally pretty fond of this trope. ''TabletopGame/ChangelingTheDreaming'' and ''TabletopGame/VampireTheMasquerade'' are particularly good examples as every sub-flavour of supernatural ("Kith" in ''Changeling'', "Clan" in ''Vampire'') has its own supernatural disadvantage.
* The ''TabletopGame/NewWorldOfDarkness'' also has the option during character creation of giving a character a flaw which could potentially hinder them and - if done right - give extra experience points. Some of the flaws include addictions, Coward, Forgetful, and Behavior Blind.
* The Traitor Primarchs of TabletopGame/{{Warhammer 40000}}. Other examples include the Emperor's failures as a father due to being too emotionally distant to treat them as much more than subordinates, or the Eldar's undying pride despite being on the brink of extinction.
** Each of the Necron Special Characters have one. Imotekh and Zahndrekh are master strategists, but Imotekh's need to personally duel the opposing leader can ruin his plans, while Zahndrekh's belief that everyone is Necron means he never uses any powerful but dishonorable weapons and plans.
** The Laughing God used the C'Tan's gluttony against them when he told them how delicious their souls are.
[[/folder]]

[[folder:Theater]]
* OlderThanFeudalism: Pretty much all ancient Greek tragedies had a main character or characters with a ''hamartia'', which is often translated to English as "fatal flaw." It was part of the basic structure for an Ancient Greek tragedy, according to Creator/{{Aristotle}}. [[Theatre/OedipusRex Oedipus]] was headstrong and didn't know when to stop, Creon in ''Theatre/{{Antigone}}'' was proud and was intent on making an example out of Antigone, Antigone was stubbornly committed to her traitorous brother...
* Shakespeare ''loves'' to give these to characters in his tragedies:
** [[Theatre/JuliusCaesar Brutus]] is extremely honorable and expects others to be, or [[AlternateCharacterInterpretation possibly]] self-centered and susceptible to flattery.
** Richard, Duke of Gloucester, a.k.a [[MagnificentBastard Richard III]], has a callous disregard for human life and an irrational lust for the crown.
** Theatre/{{Macbeth}} is blinded by power and paranoia and [[OutDamnedSpot plagued by guilt]]. He's also very wrathful.
** Lady Macbeth is overly ambitious.
** Theatre/{{Hamlet}} waited too long, and is very likely crazy. He does have a particular flaw, but what it is depends on interpretation and how he is presented. And yet in every production he is completely GenreSavvy about this:
--> "So, oft it chances in particular men,\\
That for some vicious mole of nature in them...\\
Carrying, I say, the stamp of one defect,\\
Being nature's livery, or fortune's star,\\
Their virtues else ? be they as pure as grace,\\
As infinite as man may undergo ?\\
Shall in the general censure take corruption\\
From that particular fault."
** Theatre/RomeoAndJuliet are so obsessed with each other they forget about anything else. Romeo is a bit of a hothead, too.
** Friar Lawrence thought his CrazyEnoughToWork plan would actually work.
** Theatre/{{Othello}} is too rash, not to mention gullible (to be more precise, [[HorribleJudgeOfCharacter he believes the people he shouldn't and doesn't believe the ones he should]]) and prone to [[CrazyJealousGuy jealousy]].
** ''Theatre/KingLear'' is far to proud. This causes him to exile and disown his beloved, youngest daughter who tells him the truth and gets himself stabbed in the back by his two eldest daughters who tell him what he wants to hear.
** Goneril and Regan (Lear's back-stabbing daughters) are destroyed by their shared fatal flaw: ''lust''. Their mutual attraction to Edmund from Act IV onward turns them against each other, [[spoiler:culminating in a MurderSuicide during the final scene]].
* Shown explicitly in Arthur Miller's play ''Theatre/DeathOfASalesman''. The main character, Willy Loman, is so entranced with his own dreams and desires that he denies and ignores anything contrary to his beliefs. Willy's conviction that just being well liked is enough to lead to success eventually leads to his downfall, as he can't understand why his sons, who were popular in high school, can't seem to get successful jobs. After Willy commits suicide, the play ends as a ShaggyDogStory, with [[LonelyFuneral nobody attending Willy's funeral]]. One of Willy's sons even {{Lampshade}}s his father's FatalFlaw.
* In Miller's ''Theatre/AViewFromTheBridge'', Eddie Carbone's FatalFlaw is his unrealized love for his niece, Catherine.
* ''Theatre/SweeneyToddTheDemonBarberOfFleetStreet'': Sweeney Todd's obsession with revenge against Judge Turpin (combined with waiting a little too long the first time he had him in his hands) ends up costing him everything in the end (as well as [[spoiler:his willingness to trust someone he really shouldn't have concerning his wife's fate]]).
** YMMV on the above. [[AlternativeCharacterInterpretation You could also argue that Sweeney's fatal flaw is naivety]]. "What was his crime?" "Foolishness". He failed to perceive exactly how dangerous Turpin was to his family, and all of the subsequent damage happened because of this. Case in point: it happens again. He's genuinely shocked by Mrs Lovett's betrayal - you get the feeling that even after his descent into total madness, he still can't comprehend the depths that some people will sink to.
* In ''Theatre/{{Electra}}'', the title character's unrelenting lust for revenge combined with her nigh incestuous obsession with her brother, Orestes, and her father, Agamemnon, makes for her fatal flaw.
* Though not fatal, [[Theatre/MyFairLady Higgins']] superior attitude causes Elisa to leave him.
[[/folder]]

[[folder:Video Games]]
* Fire Emblem: Genealogy of the holy war
The main character Sigurd of Chalphy is noble and caring, but is a terrible military commander who relies a little too much on military force to get the job done. worse, he is reckless,naive and short-sighted. All these flaws would ultimately have fatal consequences for him and his soldiers.
* ''Franchise/MassEffect'':
** For all their intelligence the salarians' relatively short lifespans appear to make them [[DidntThinkThisThrough VERY shortsighted when it comes to decision making on a galactic scale]]. Uplifting the krogan without taking into account the long term consequences of their birth rate, especially when freed from the natural mortality rate of Tuchanka. Creating the genophage but not expecting the turians to use it without their permission. Worse still it seems they feel the [[spoiler: yahg]] are a great new prospect for uplifting into galactic society. Anyone familiar with this race can see the glaring flaws in that strategy a mile away.
*** For those who ''don't'' know the yahg? We see only two specimens. One manages to escape in the midst of a Cerberus attack, slaughtering better armed, trained, and equipped soldiers with nothing but its bare hands. The other managed to [[spoiler: take over the job of Shadow Broker and has been running the gig from behind the scenes for years... and still manages to be a very difficult fight, despite [[GeniusBruiser being an intellectual.]]]]
* In ''VideoGame/{{Iji}}'', the titular character eventually manages to defeat the seemingly-invincible Assassin Asha... with the simplest weapon in her arsenal, the shotgun. Although Asha has lightning-fast reflexes, years of training, and an active teleportation device that lets him dodge nearly any attack conceivable, [[ArrogantKungFuGuy he considers evading such antiquated technology beneath him.]]
* ''VideoGame/DungeonKeeper 2'': Turned on its head in execution, but still used perfectly straight. One of the earlier campaign missions pits you against Lord [[ThemeNaming Avaricious]] in his impenetrable fort. The elegant way to win (as opposed to a head-on slaughter) is to have your imps mine away almost all of the gold beneath his realm, enraging the man enough to lead the charge personally. [[KarmicDeath It doesn't end well.]]
* ''EienNoAselia'': Yuuto's fatal flaw in would be his stubbornness and anger. His life to this point has been more difficult than it needed to be due to the former, and because of the latter [[spoiler:he nearly kills Kaori.]]
* In ''FateStayNight'', [[spoiler:Gilgamesh]] has a titanic ego and tendency to underestimate his opponents.
** Shirou's need to [[ChronicHeroSyndrome save everyone]] constantly causes him problems and [[spoiler:is what eventually led to him becoming Archer.]]
*** It also gives him severe self-esteem issues and a martyr complex. (If [[TheAce Saber]] weren't around to protect him, Shirou would be dead before the second cutscene.)
* In ''VideoGame/TheSimsMedieval'', every Sim in your kingdom has some sort of fatal flaw that directly affects their mood or performance (Gluttons have to eat more frequently, and require more than one meal to be fully satisfied; [[CasanovaWannabe Licentious]] Sims get in a bad mood if they don't kiss or [[GRatedSex Woohoo]] with other Sims after a set amount of time). Succeeding in certain quests allows them to drop their fatal flaw and replace it with a Legendary Trait, which can't be selected during character creation.
* In ''VideoGame/{{Touhou}}'', the Lunarians as a whole has a titanic ego and tendency to underestimate those they believe to be impure. To their credits, they ''are'' more powerful than most people in Gensokyo. [[spoiler: Their arrogance eventually render them vulnerable to Yukari's {{plan}}... to steal Lunarian sake, Now that's just petty.]]
** Note that in ''Touhou'', a lot of people have the FatalFlaw of [[{{Pride}} overconfidence]], but the most vulgar display of it is by Tenshi, ''[[ForTheEvulz who destroys the Hakurei shrine just to experience the thrill of being a]] BigBad''. She gets what is coming to her... [[SubvertedTrope Until you play her story mode, where she single-handedly fights most of the cast and proves that she was just holding back the entire time.]]
* Rufus of ''VideoGame/{{Deponia}}'' has a ''tremendous'' ego. Not only does this tend to piss off quite a lot of people, it also means that he rarely pays attention to potential problems with his plans or [[BunglingInventor inventions]].
* Raziel from ''SoulReaver'' is too rash and ends up being an UnwittingPawn.
* Reptile from ''Franchise/MortalKombat'' is far too trusting and sides with any BigBad on the promise that his people will survive. He dies in every game.
** Scorpion is hell-bent on revenge for his clan, leading him to kill his rival, the elder Sub-Zero, then later plotting revenge against the Elder Gods when they bring back the Shirai-Ryu as zombies. In ''MortalKombat9'', [[spoiler:he was on the verge of giving up his desire to kill Sub-Zero under Raiden's guidance, until Quan Chi manipulates him with images of the Lin Kuei's massacre of his clan, including one of Sub-Zero killing Scorpion's wife and child himself, driving Scorpion to kill Sub-Zero in a blind rage and making him forevermore a pawn of Quan Chi.]]
** Kung Lao succumbs to pride at his detriment through the course of ''Mortal Kombat 9''. He boastfully accepts a fight with Scorpion which gets him immediately eliminated from the tournament then later [[spoiler:dies whilst grandstanding after defeating Kintaro, courtesy of a NeckSnap from Shao Kahn]].
* The ''VideoGame/WorldOfWarcraft'' is populated with the likes of Arthas, Grom, Illidan and Kael'Thas [[WellIntentionedExtremist who use drastic but well-intentioned methods when dealing with a crisis]].
* ''VideoGame/TheLastOfUs'': Quite a lot of the characters, but Henry and Sam share one. [[spoiler:Normally, BigBrotherInstinct is seen as a positive trait, , but [[DeconstructedTrope here]], Henry is far too protective of Sam and consequently Sam never learns to fend for himself, making him TheLoad. After he is bitten by an infected, Henry is forced to kill his little brother and takes his own life out of despair]].
* Most incarnations of ''Franchise/SonicTheHedgehog'' are presented as overly cocky and prone to acts of recklessness, a lot of which are exploited by foes or end up with him making a detrimental mistake. In the games alone, Eggman took advantage of an opening left by Sonic's arrogance in ''VideoGame/SonicUnleashed'', while in ''VideoGame/SonicLostWorld'' his over eagerness to swat away Eggman's new toy left another antagonist, the Deadly Six, free to bring havoc, an act which almost led to Earth being drained of it's life and Tails being transformed into a robot).
* ''VideoGame/{{Persona 4}}'' uses this as a major plot point, confronting most of the party (and at least one other character) with their {{Fatal Flaw}}s in the form of shadows that act as [[{{Flanderization}} gross caricatures]] of them (Shadow Chie becoming a dominatrix to represent Chie's need to control Yukiko to feel better about herself, Shadow Kanji being a CampGay stereotype to represent Kanji's [[RealMenWearPink insecurity about his girly hobbies]], etc.) Accepting and overcoming these flaws instead of just denying them is the only way to truly defeat the shadows and transform them into their Personae.

[[folder:Web Animation]]
* ''HappyTreeFriends'': Almost all the characters have fatal flaws. Lumpy is inept at everything he does, Nutty is constantly hyperactive and addicted to sugar. Flaky has fears and phobias about just about anything and everything. These flaws do indeed prove to be fatal by the end of the episode. Sgt. Flippy's untreated post-traumatic stress disorder, always proves to be fatal for ''everyone else around him'' by the end of the episode.
* [[WebAnimation/{{RWBY}} Weiss's]] flaw is pride, which cripples her friendships and ability to work as part of a team.
[[/folder]]

[[folder:Web Comics]]
* ''Webcomic/TheOrderOfTheStick'':
** Vaarsuvius has the fatal flaw of Pride in zir magic power and intellect, which both leaves zir wide open for the trauma factor of being completely powerless to stop horrible things from happening to his/her friends and loved ones and drives zir to accept a DealWithTheDevil rather than experience that feeling of helplessness again. Later zhe starts working on that, though, and is limiting zir to low-level enhancements unless zhe needs them, as opposed to just going all out.
** Redcloak, whose inability (Conviction) to back down from the path and plan he's chosen, despite all the senseless sacrifices, really bites him in ''Start of Darkness.''
** Haley's flaw is greed, although unlike most examples, she's vaguely justified in this: [[spoiler: her father is being ransomed for a small fortune and she became an adventurer to get enough money to save him from further imprisonment.]] At one point, the gold and treasure she owns is destroyed in a fire, and Haley's shock is so great that it renders her ''literally'' unable to speak for the next hundred or so strips. (One of the reasons she likes [[WideEyedIdealist Elan]] so much is because [[ThePowerOfLove his presence]] encourages her away from this.)
** Miko Miyazaki, a massive KnightTemplar who refuses to believe that anything she does is wrong. Instead, she imagines [[ConspiracyTheorist a massive plot brewing behind the scenes]] just to enable this belief. [[spoiler:It's only when she's moments away from death that she starts to question any of her actions, but by then, it's way too late.]]
** Nale is a SmugSnake who thinks ItsAllAboutMe. [[{{Pride}} His massive ego]] and tendency to slip into EvilGloating have only hampered his ability to competently execute plans in the past, resulting in numerous defeats and a trail of kobold corpses in his wake. It's even noted in-universe that if Nale wasn't such an arrogant egomaniac, he would actually be dangerous. [[spoiler: He ends up in over his head when he makes a series of incredibly short-sighted choices on account of his pride, which first costs him Girard's gate, then his adventuring party, and finally his life.]]
* In [[http://goldencomic.blogspot.com/ Golden]], a take-off of the standard fairy tale, the hero (and his less useful older siblings) are all sent off on the Quest because of their father's fatal flaw: GREED. The king wants gold very, very much. In fact, that whole family loves gold just a little too much to be healthy.

[[folder:Web Video]]
* WebVideo/TheNostalgiaCritic is trying to work on his temper and cynicism, but his insecurities about seemingly never being good enough are still getting in the way.
* LetsPlay/SomethingAwfulDungeonsAndDragons: Minerelle's Cowardice, Joey's Greed, Miriam's [[UnstoppableRage Anger]], Gibnaf's [[ChronicHeroSyndrome Idealism]], and Kod's Pride. [[spoiler: The former is particularly notable as Minerelle's strict running policy led her away from Joey and Kod, meaning when she went down there was no one to save her from being KilledOffForReal.]]
* In ''TheLizzieBennetDiaries'', Lizzie's pride and inability to change her mind once it's made up has caused misunderstandings and problems between her and others, particular Darcy and Lydia. Fortunately, through CharacterDevelopment, she starts to work on improving from those flaws.

[[folder:Western Animation]]
* ''WesternAnimation/DannyPhantom'': Danny has two: His [[StartofDarkness darkness]] which manifests into him constantly abusing his powers which if he isn't careful, would result in a BadFuture. The other is his emotions which he has a trouble time containing--the latter is often used to his advantage by some of his baddies. Unlike the first example, this is one he has yet to resolve.
* Robin of ''WesternAnimation/TeenTitans'' tends to become so devoted to one goal, he neglects other aspects of his life until the issue is resolved. This characteristic has damaged, or even risked losing, many of his friendships and sometimes even proved his undoing.
* While it is undeniably played for laughs most of the time, Omi, from ''WesternAnimation/XiaolinShowdown'' has a massive superiority complex, constantly talks down to his friends as if they're beneath him, and it has gotten him in trouble more than a few times.
** Also demonstrated with Raimundo. Due to being singled out of a promotion and treated as inferior by Omi, again, Raimundo [[FaceHeelTurn betrayed the team]].
* In ''WesternAnimation/AvatarTheLastAirbender,'' Iroh's bizarre FatalFlaw is his love of tea. While normally the wisest and more sensible figure in the entire series, he makes some monumental mistakes when around the stuff. Once, when having to hide his identity as a Fire Bender, he used his bending to heat up some cold tea and nearly blew his cover. Earlier than that, when finding a plant whose leaves were either the world's most refreshing tea or pure poison, he ground it up and drank it due to temptation. [[spoiler: It was poison.]]
** Azula is another example. Her belief that people can be controlled through fear proved to be a mistake. Also Azula's determination to prove herself to her father, mainly because she believed [[spoiler: that her mother only cared for Zuko, proved to be a serious issue that led to a [[VillainousBreakdown villainous breakdown]] at the end of the series.]]
** Aang's flaw is his [[HonorBeforeReason conviction]]. He was raised as a dedicated pacifist, and though [[MartialPacifist he will fight if necessary,]] he won't kill. When his opponent is the BigBad who slaughtered Aang's people and oppresses the populace of two nations, this turns out to be a bad thing.
* Discord from ''WesternAnimation/MyLittlePonyFriendshipIsMagic'' loves exploiting these to [[BreakTheCutie break ponies]] ForTheEvulz, and [[ManipulativeBastard is very good at it]], but has one himself, namely his own pride and [[EvilCannotComprehendGood inability to truly understand how strong the bond of friendship really is]]. Both of these blind him to the fact the mane cast has reforged their friendship and the Elements of Harmony, the one thing on earth that can possibly defeat him, work again until he gets a [[ThePowerOfFriendship friendship]] [[CircleOfFriendship powered]] WaveMotionGun to the face.
** All six of the main ponies suffer from some defining flaw that usually serves as a pivot for most of their personal dilemmas and even expand into full blown disasters when exacerbated enough (almost ''all'' of them have suffered a SanitySlippage at one point):
*** Twilight's [[SuperOCD perfectionist qualities]] and neuroses over potential failure or disappointing peers.
*** Rainbow Dash's narcissism and [[ItsAllAboutMe self obsession]].
*** Applejack's stubborn pride or self righteousness.
*** Rarity's vanity or materialistic nature.
*** Fluttershy's [[ExtremeDoormat lack of backbone]].
*** Pinkie Pie's [[InnocentlyInsensitive tactlessness]] and [[CloudCuckooLander overall eccentricity]].
* ''{{WesternAnimation/Gargoyles}}'' have many examples. One of the strongest examples is Demona and her refusal to take [[NeverMyFault responsibility and accountability]] for her actions. After all [[spoiler: Demona was the reason why her Gargoyle clan was destroyed by the Vikings and why the surviving clan members got cursed, which is the genesis of the series.]]
* ''WesternAnimation/AmericanDad'':
** Stan's so uptight that when he enjoys something, he can't stop.
** Francine gets herself in trouble because of her need to have a more exciting life.
