History Main / FatalFlaw

** Carolina's {{Pride}} and her need to be better than Agent Texas has caused several issues for herself, her teammates and others. By taking the two A.I. meant for Washington and South so she could compete with Tex, Carolina only fueled South's envy and eventually [[spoiler: resulting in South leaving her brother for dead]]. During a training simulation with Tex to capture the flag, Carolina accidentally [[spoiler: killed Biff, Temple's friend]] and callously dismissed the event, having been more focused on defeating Tex. This would lead to [[spoiler: Temple's StartOfDarkness and years later, hatch a plot to kill all freelancers.]]

* [[TheUnapolegitic Shamelessness]]

* [[EasilyForgiven Forgiveness to a fault]]

[[folder: Art]]

* [[NeverMyFault Inculpability]]

* [[WideEyedIdealist Idealism]]

** Superman's ArchEnemy ComicBook/LexLuthor has a nasty combination of Pride and Envy; [[FeeelingOppressedByTheirExistence he feels oppressed by the mere existence of people who are better than him]], gets super-paranoid about them, and [[EvilCannotComprehendGood cannot comprehend that they might not feel the same]]. The most common target is Superman because he's beloved in a way Lex never is (because Supes is a NiceGuy and Lex tops out at CondescendingCompassion), but quite frankly if it wasn't him Lex would find someone else to [[NeverMyFault blame for his own inadequacies]].

** Superman's ArchEnemy ComicBook/LexLuthor is a petty, prideful egomaniac who often envies Superman to the point where he gave up a chance to become a god and create a utopia in ''Comicbook/TheBlackRing'', because on one condition is that he can't use his power to do evil. In this case, killing Superman. To him, even godhood is meaningless if it means he must let go of his hatred towards the Man of Steel.
** Likewise, ComicBook/{{Darkseid}} is overconfident, often underestimating his opponents and not using his powers to their full extent.

* Lucha wrestler's attachment to their masks is SeriousBusiness.

** Jin Kisuragi, headmaster of Hope's Peak, had his devotion to the academy's mission. His desire to help talented students succeed in life meant that he had a tendency to overlook the fact that some of his more talented students were ''spectacularly'' unstable people who would likely use those talents for evil. The Steering Committee he reported to were even worse in this regard, as at least Jin realized enough was enough when a student (who was enrolled behind his back) manipulated the Student Council into murdering each other. The Steering Committee covered the incident up.

** Phoenix himself has his tendency to look before he leaps; sure, sometimes his recklessness serves him well and he comes across decisive evidence someone more rational would never find, but other times it backfires horribly on him, like the times he showed murderers decisive evidence against him and and got it destroyed (and himself injured) for his troubles, trusting Dahlia Hawthorne, running across a rickety bridge that was ''on fire'' (it breaks under him and he gets dumped into the river below), and accepting what would turn out to be a piece of forged evidence that ruined his career without a second thought, among other things.

[[folder:Western Animation]]
* Rob from ''WesternAnimation/TheAmazingWorldOfGumball'' has [[PoorCommunicationKills an inability to communicate]] as his flaw. He kidnaps Banana Joe's mother so she can paint the future, and attempts to brainwash his former classmates to escape to an unknown place. [[SurprisinglyRealisticOutcome This gets him beat up by a T. rex]].
* ''WesternAnimation/AmericanDad'':
** Stan's so uptight and bullheaded that he'll [[KnightTemplar cross any line and go to any extreme to enforce his narrow-minded and oftentimes ridiculous sense of justice]]. When something breaks through his uptight nature and he actually enjoys something, he can't stop.
** Francine gets herself in trouble because of her need to have a more exciting life.
* ''WesternAnimation/{{Arcane}}'': Vi tends to be impulsive and short-tempered, [[LeeroyJenkins too often acting without a plan]]. In Act 1, she leads the kids on a big heist without telling Vander what they're up to, leading to the events of the present. In Act 2, Vi instantly gets into a fight with [[TheDragon Sevika]] upon seeing her; while she almost wins, learning what happened to her sister gets her stabbed, requiring saving by Caitlyn. Vi complains that Sevika got away and will be telling Silco that they're here, but Caitlyn bluntly points out she's the one who exposed herself first. [[spoiler: In Act 3, she pushes Caitlyn away and ignores Jayce's warning that she won't make it alone. Vi shows up at The Last Drop and barely survives defeating Sevika again, resulting in both her and Caitlyn being kidnapped, which directly leads to the events of the ending.]]
* ''WesternAnimation/AvatarTheLastAirbender'', and it’s sequel series ''WesternAnimation/TheLegendOfKorra'', has several:
** Iroh's bizarre Fatal Flaw is his love of tea. While normally the wisest and most 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, as she's a [[TheSociopath psychopath]] with ControlFreak, [[ThePerfectionist perfectionist]], and [[TheParanoiac paranoiac tendencies]]. She simply sees people as objects -- she manipulates them and expects them to behave accordingly. But she can't handle ''not'' being in control of everything. Her belief that people can be controlled through fear flew in her face, and her determination [[WellDoneSonGuy 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 at the end of the series. And when Mai and Ty Lee, the people she thought she had the most control over, turn against her, the shell cracks off the nut, and her relatively subdued madness comes to the forefront and turns into full-blown paranoia, leading her to banish everyone around her for imagined slights and plots against her. Finally, when there's no one around for her to control, whatever remaining sanity she had is whittled to the point that she's reduced to total lunacy and {{Ax Craz|y}}iness.]]
** Ozai shares the same flaws as Azula -- EvilCannotComprehendGood, {{Pride}}, [[ThePerfectionist extreme perfectionism]], [[ItsAllAboutMe megalomania]] and [[TheParanoiac paranoiac tendencies]].
** 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 descended from the man who slaughtered Aang's people with the intent of continuing such a legacy and oppresses the populace of two nations, this turns out to be a bad thing. [[spoiler: [[TakeAThirdOption He finds a solution in the end]]: De-power the BigBad.]]
** Zuko's misguided decisions in an effort to [[WellDoneSonGuy gain his cruel father's acceptance]]. It takes a while for him to realize Ozai has no love for his wife, his brother, or even his children.
** Katara is known to hold grudges to the point where she could kill someone, especially if she was betrayed or if her loved ones are put in danger. When she runs into [[spoiler:Jet after he had betrayed her trust]], she immediately attacked him. She flat out told Zuko after [[spoiler:he joined the gang]] that if she thinks he might hurt Aang, she would personally kill him. And when she confronted the man whom she believed killed her mother, [[spoiler:she ''bloodbended'' him]].
** Most members of the New Team Avatar has one, Korra nearly gets killed or depowered on several occasions by her aggressive and proud nature. She gets better, at least. Bolin, meanwhile, repeatedly gets himself into trouble through his trusting nature which stemmed from Mako's overprotective nature. Mako's inability to spit anything out or relax for four seconds never gets him into any worse trouble than a difficult breakup. Lin Beifong has trouble letting go of old resentments that she ends up hurting others who aren't even part of her resentment like her niece Opal, not so dissimilar to Katara as mentioned above. Tenzin can be surprisingly naïve for a middle aged man and has to learn not to compare himself to his father.
** Fittingly for a SatanicArchetype, Vaatu's flaw is his {{Pride}} -- more specifically, his belief that mere humans could never pose a threat to a supremely powerful spirit such as himself.
** [[FallenHero Kuvira]]'s flaw is her utter devotion to her goal of a safe and unified Earth Empire. While this makes her a {{Determinator}}, it also gives her tunnel vision and sends her further and further into outright villain territory. She also adamantly [[NeverMyFault refuses to take responsibility for the consequences of her actions]], an issue she's had since childhood as revealed in the ''[[ComicBook/TheLegendOfKorraRuinsOfTheEmpire Ruins of the Empire]]'' comic.
** Raava, Vaatu's GoodCounterpart, suffered from a similar flaw as he did. When battling Vaatu, she dismissively told Wan not the meddle in their affairs, whereas Vaatu was smart enough to manipulate Wan into helping him. While she chided Wan for his mistake, she also contributed to that said mistake as well due of her dismissive nature preventing her to explain to the first Avatar why freeing Vaatu was a bad thing, which enabled the GodOfEvil to manipulate him.
* ''WesternAnimation/BatmanTheAnimatedSeries'': ComicBook/TheJoker's AttentionWhore status sometimes gets the better of him.
** When the UnexpectedInheritance he got from a deceased rival turned out to be fake, Joker was enraged. Plus, King Barlowe knew Joker would binge-spend on the fortune and get a visit from the IRS, at which point the clown will either get jailed for tax evasion or admit he was conned by a dead man (which he won't do as it would turn him into the ButtMonkey of Gotham).
** [[Recap/TheAdventuresOfBatmanAndRobinE18MakeEmLaugh Another]] is when he was booted out of a comedy show and got back at the ones responsible by hypnotizing them into becoming supervillains in order to cement himself as the "funniest man in all of Gotham", only to end a laughing stock afterwards.
** When his moll Harley managed to successfully capture Batman so that she and the Joker can truly live together, the clown instead pushed her out of a window to her possible death. It was revealed that Batman duped Harley into doing it because he knew that [[TheOnlyOneAllowedToDefeatYou the clown's ego would never allow someone else to kill Batman]].
* In ''WesternAnimation/BigHero6TheSeries'', [[BigBad Obake's]] flaw is his inability to recognize that just because you ''can'' do something doesn't mean you ''should''. Granville's lack of supervision combined with his brain damage has driven him to complete his goals, no matter how dangerous or who gets hurt in the process.
* Bob from ''WesternAnimation/BobsBurgers'' gets obsessed when it comes to one-upping his rival from across the street, Jimmy Pesto. Oftentimes, in episodes featuring Jimmy, Bob's constant need to beat him causes him to do something that ends up putting him or his family in a worse position. One example is in ''Recap/BobsBurgersS7E21ParadersOfTheLostFloat", where Bob and Jimmy are in competing floats in a parade float contest. The two floats first try to sabotage each other, causing their decorations to fall off, then try to race one another to arrive at the judge's table first and bribe the judges into giving them the prize. Bob tries to take a detour to beat Jimmy's float, but just ends up getting him and his family lost in town.
* ''WesternAnimation/CodenameKidsNextDoor'': [[BrokenAce Chad Dickson]]'s fatal flaw is his {{Pride}}. He is obsessed with being the best, even at the detriment of the organization he loves so much. [[spoiler:Part of why his FakeDefector act was so convincing is because the idea that he wouldn't want someone tarnishing his legacy after he was decommissioned wouldn't really be out of character for him. Eventually, when he's denied the honor of being Earth's representative for the Galactic Kids Next Door, he undergoes a slow burn of a VillainousBreakdown, exacerbated by being forced into a ChainedHeat situation with the person who (unknowingly) took that honor from him, Nigel Uno/Numbuh 1, the main protagonist of the series. Not helping things is that Nigel is completely unaware of his FakeDefector status and thus is extremely belligerent towards him. Eventually, the situation deteriorates and all the pent-up resentment culminates in a DuelToTheDeath between them, which Chad loses]].
* ''WesternAnimation/DannyPhantom'':
** Danny has two: His [[StartofDarkness darkness]], which manifests into him [[ScrewTheRulesIHaveSupernaturalPowers constantly abusing his powers]] which if he isn't careful, would result in a BadFuture. The other is his emotions which he has a hard 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 since at the end of the day he's still a HormoneAddledTeenager.
** His ArchEnemy Vlad also had two; {{pride}} and [[GreenEyedMonster envy]]. He was a BrokenAce who lost the love of his life to his best friend after getting injured in a FreakLabAccident, and spent the entirety of his adult life [[EntitledToHaveYou seething over the life he felt he should've had]] due to his arrogance, thinking too highly of himself and his ambitions and being unwilling to compromise them. When he gets what he wants (or it no longer becomes an option, like in the BadFuture) [[HiddenDepths he's actually a rather good and kind guy]]. It's just that when he doesn't he's quick to turn to obsessive bitterness and hatred, leading him [[EntitledToHaveYou to TAKE what he wants if possible]].
* In ''WesternAnimation/DarkwingDuck'', Darkwing's massive ItsAllAboutMe attitude and his need to constantly hog the spotlight land him in plenty of trouble. He always has to make a dramatic entrance, takes great pains to ensure the world is well aware of who he is, and will throw a huge fit anytime another superhero (especially Gizmoduck) comes out to help. All of this gives the villain the chance to get away clean, or worse, win outright. He does realize he made a huge mistake, but [[AesopAmnesia it never sticks]].
* ''WesternAnimation/EdEddNEddy'':
** The most obvious Fatal Flaw is Eddy's {{Greed}}. Much of the driving force in many episodes is Eddy trying to scam other kids out of their money so he can gets his hands on jawbreakers (or just keep it for himself). Many of Eddy's schemes [[CutLexLuthorACheck would be legitimate business ventures if he applied himself]]. The trouble is that Eddy's obsession with making as much money as possible keeps ensuring that FailureIsTheOnlyOption for him.
*** Eddy's impulsiveness is also a recurring issue for him - when he wants something, he wants it ''right now'' and will chase after it with little regard for the consequences.
** Double D's [[ExtremeDoormat spinelessness]] means that he's often dragged along with Eddy and Ed's shenanigans whether he wants to or not and his inability to assert himself with his friends or the neighbourhood kids often results in him being punished alongside Eddy and Ed even when he was innocent and/or tried to stop the other two. He also has a bad habit of letting his reputation of the smartest kid in the cul-de-sac go to his head at times and he ''has'' to be right about everything, making him quite inflexible and not good at bouncing back when things backfire on him.
** Ed's stupidity is his flaw, since he's very gullible, prone to making mistakes and often doesn't understand what's going on, often meaning that more short-tempered characters like Eddy or Sarah take their anger out on him or him getting manipulated easily.
** Sarah's Fatal Flaw is Wrath. There is rarely an episode where she isn't either yelling at someone or beating them up, and the other kids in the cul-de-sac rarely help her as a result.
** Kevin's is arguably {{Pride}}, being an arrogant JerkJock who likes to think he's the coolest guy around.
** The [[TerribleTrio Kanker]] [[AllWomenAreLustful Sisters]], who all fall under {{Lust}}, as their habit of subjecting the Eds to unwanted kisses and affection actually just terrifies them and drives them further away.
** Jimmy's childishness mean that he's an easy target for bullies (especially when Sarah isn't around) and he's often dismissed and patronised even when he does have legitimate concerns or opinions.
* ''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.]]
** Goliath's flaw is his anger and need for revenge, especially if someone in his clan is hurt. Such as in ''Deadly Force" when he mistakenly believed that Elisa was nearly killed by the gangster Dracon and Goliath ruthlessly hunted him down and in "Hunter's Moon", his desire to kill the ones who almost killed his daughter Angela overruled his common sense.
* Every single Pines family member in ''WesternAnimation/GravityFalls'' has at least one critical flaw that tends to kickstart the conflict of the stories:
** Dipper's flaw is his insecurity; Dipper has done some very stupid and very dangerous things in an effort to prove himself, such as reciting a curse ''out loud'' in an attempt to be taken seriously by federal agents. In addition, these insecurities have given Dipper something of a defeatist mentality, which impairs his ability to fight back in difficult circumstances.
** For Mabel, [[ItsAllAboutMe her selfishness]] meant that she often never considers what everyone else wants and instead, prefers that they do what she wanted to do. She is also shown to be quite insensitive to Dipper's feelings as despite the fact that she knows that Dipper is troubled, she still constantly picks on him. This flaw is what ultimately caused a rift between the two and allowed Bill to exploit her emotional state in order to directly cause Weirdmageddon.
** Stan has three; First, his issues with trusting and confiding in others, which comes back to bite him in ''Not What He Seems''. Second, his temper, which [[spoiler: cost Ford his dream scholarship and almost doomed the entire world when Ford corrected his grammar, prompting Stan to attack him, thus breaking up a magic circle that would have destroyed Bill]]. Third, similar to Mabel, is his selfishness and his obliviousness to it. [[spoiler: Part of the reason he and Ford had a falling out was Stan assuming that the latter would be comfortable with not going to his dream college and feeling threatened when he realized Ford was seriously thinking about it.]]
** The Author (aka [[spoiler: Stanford Pines]]) lets his obsession with his own work and science drives away everyone he cares about including his brother and Fiddleford. He is also ''really'' bad at just explaining things, usually due to trust issues or lack of communication skills. [[spoiler: Among other things this leads to his assistant leaving and going mad, a fight with his brother that gets him sucked into another dimension for about thirty years, only trusting one person with world-saving secrets, and being part of a chain of events that kicks off [[RealityIsOutToLunch Weirdmageddon]].]] Adding to his poor communication, he assumes that the people in his life won’t be emotionally affected by his choices, both assuming that [[spoiler:Stan would be fine with him going to West Coast Tech instead of sailing around the world together and that Mabel would be fine with Dipper staying in Gravity Falls as his apprentice instead of going home to Piedmont with her. ''They weren’t.'']]
** Two common flaws for all of the Northwests is both Snobbery and Greed. Nathaniel Northwest [[spoiler:convinced the local lumberjacks to build his mansion in exchange for an annual party. After it was finished, the Northwests literally shut the gate in their faces. This escalated into the death of a lumberjack and cursing the family for 200 years.]] His descendant Preston is even worse when he [[spoiler: tries to join up with Bill during Weirdmageddon.]] Only Pacifica was able to break out.
** Gideon’s is Obsession. He’s determined to be with Mabel, despite the fact that she doesn’t want anything to do with him. It’s not until the GrandFinale that it sinks in that she doesn’t love him. In addition, [[spoiler:When he found out that Journal 1 was missing, he chased Dipper and Mabel to get it, despite the fact that he’d ''won'' at that point: he had the Shack, Waddles, and two of the journals. This resulted in the twins and Stan defeating him and being sent to prison.]]
** Like Dipper, Robbie also has insecurity. He was genuinely threatened by Dipper’s crush on Wendy despite it obviously being a PrecociousCrush to the point where he was willing to fight Dipper. He’s also implied to be nervous about his skill as a musician, [[spoiler:ripping off a song in order to win Wendy back. Unfortunately, it also ''brainwashed'' her, which resulted in her dumping him.]]
* ''WesternAnimation/HeyArnold'': Helga Pataki's primary flaw is insecurity. She is unable to be her true, kind, articulate and intelligent self due to her fear of being shunned by others, so she resorts to being TheBully instead. Arnold would likely return her affections if she were to stop treating him like garbage and be herself. If she were to try harder in school, her neglectful parents would probably pay more attention to her (but as we've seen with her older sister Olga, [[StepfordSmiler that might not be a good thing]]) and while she might get a few snickers from [[TheBully Harold]] or the others, she'd be in a much better place and would be happier for it. Her nanny Inga in "Helga and the Nanny" even tells her that she's doomed to suffer as long as she continues to push others away.
** It's not addressed much but Phoebe has a bad habit of going DrunkWithPower whenever she's given any kind of authority and several of her ADayInTheLimelight episodes show her going completely overboard, particularly the episode she's made hall monitor or in "Phoebe Breaks A Leg."
** Rhonda's is her snobbery, as even though she is a kind person at heart, her AlphaBitch behaviour means that whenever she gets knocked down a peg, people are rarely sympathetic towards her and she struggles to relate to her peers or cope without her wealth and popularity to fall back on, such as "Rhonda's Glasses" or "Rhonda Goes Broke."
* ''WesternAnimation/IAmWeasel'' has severe ChronicHeroSyndrome which sometimes makes things worse for the world rather than better.
* ''WesternAnimation/InfinityTrain'' is built around this. Each season focuses on a new passenger of the eponymous train, who can only leave when they've resolved a notable personality flaw.
** Season 1 has Tulip. Her issue is a general unwillingness to work through her feelings, preferring to bury them rather than accept imperfection and move on.
** Season 2 has Jesse. He [[IJustWantToHaveFriends wants people to like him]] so much that he won't take sides, lets people walk all over him or even [[ToxicFriendInfluence talk him into doing things]] that he knows are wrong.
** Season 3 has Grace and Simon. Grace's pride is what led to her starting the Apex to begin with because she [[spoiler: couldn't own up to the fact that she didn't actually know what the numbers meant, and only wanted recognition]]. Meanwhile, Simon's obsessive nature means that once he gets an idea into his head, ''nothing'' will convince him to reexamine it or consider he may not have all the information, which actively contributes to his [[FantasticRacism worst]] [[ControlFreak character]] [[IgnoredEpiphany traits]].
** Season 4 has Min-Gi and Ryan. Min-Gi’s self confidence issues cause him to abandon his music dreams for university and a "safe" career in finance. Ryan tends to leap before he looks, which results in his career in music going nowhere. Both issues weigh heavily on their friendship.
* ''WesternAnimation/InvaderZim'': Zim is so blindly arrogant that not only does he refuse to second-guess himself, he won't accept others doing the same. He single-handed ruined the first Irken invasion when he launched a massive assault... [[EpicFail and didn't realize he was assaulting his own planet. And shot down any underlings who tried to point that out]]. To this day, he still does not recognize what he did wrong there.
* ''WesternAnimation/JackieChanAdventures'':
** Shendu is powerful and cunning, but his [[ChronicBackstabbingDisorder untrustworthiness]] and unwillingness to share power with others causes him to double-cross numerous characters, costing him many important victories and advantages later on.
*** Denying the Dark Hand the riches he promised them leads them to follow him back to his palace in order to take their price, and they also unknowingly transport [[LittleStowaway Jade]] with them, allowing her to [[BigDamnHeroes deny Shendu's certain victory over Jackie]].
*** His [[ICanRuleAlone decision to leave his siblings to rot in the Netherworld]] centuries ago later bites him back in the ass, when he eventually meets the disgruntled family again as an incorporeal and depowered spirit.
*** Trying to steal the Demon Archive from Jade while she was the Queen of the Shadowkhan by deceiving her resulted in her destroying it.
*** Also, Shendu betraying [[spoiler:Daolon Wong]] after his resurrection makes [[spoiler:the old wizard vengeful enough to the point that after being arrested, he tells the heroes Lo Pei's chi spell that is used to turn Shendu back into a statue]].
** Greed for the main trio of the Enforcers, which is why their first two attempts at turning good failed.
* In the animated short, ''WesternAnimation/LifeInATin'', it's the main character's {{workaholic}} tendencies. When given the chance to take a day off and spend time with his child, he doesn't relent. [[spoiler:It ends up killing him.]]
* ''WesternAnimation/MiraculousLadybug'':
** Most Akumas are created by exploiting someone's fatal flaws to the point where they create a conflict that Hawk Moth can exploit to brainwash them; in the first episode, for example, Stormy Weather comes into being because Aurore is jealous of Mirelle winning a contest instead of her.
** Marinette has her impulsivity and tendency to [[ComplexityAddiction overcomplicate things]]. A good number of Akumatizations were caused by some reckless decision that Marinette made, and part of the reason her love life is so complicated is that she absolutely ''refuses'' to take the BoringButPractical route and just ''tell her crush how she feels''.
** Adrian has his passivity; life with [[NeglectfulParents a father who never listened to him]] has convinced him that his own opinions don't matter and that he can't actually change things in his civilian life, which has resulted in him letting [[SpoiledBrat Chloe]] and [[ConsummateLiar Lila]] walk all over him.
** Alya's is her recklessness and tendency to focus on her latest scoop at the expense of others.
** Chloe has [[AesopAmnesia her utter inability to learn a lesson]]. She just keeps getting involved in the same problems over and over until the people trying to help her give up.
** Part of the reason that Chloe is such a brat is because the two people she's closest to- her father Andre and best friend Sabrina- have a lack of backbone as their fatal flaw. Neither of them are able to stand up to her, so she's used to considering them resources she can use to get what she wants.
** Hawk Moth would never admit it, but the dude is having fun being a CardCarryingVillain, resulting in him ignoring or rejecting ways to solve his core problem ([[spoiler: his wife being in a coma due to using a broken Miraculous]]) in favor of the same old 'get Ladybug and Black Cat Miraculous and use them to make a wish' plan that keeps failing over and over.
* ''WesternAnimation/MyLittlePonyFriendshipIsMagic'':
** 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). While downplayed later in the series due to CharacterDevelopment, they're still present:
*** 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]].
** Discord 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. While he gradually grows out of the latterr flaw via CharacterDevelopment following his HeelFaceTurn, his pride is still his greatest weakness and continues to blind him to threats.
** The ArcVillain of the fifth season premier, Starlight Glimmer, has a big one: [[DidntThinkThisThrough a lack of common sense]]. When faced with a problem, personal or otherwise, Starlight's first response is to use her absurd magical power to make it not a problem anymore, and she never thinks of the consequences until they've come back to bite her. Her childhood friend never contacts her again after getting his Cutie Mark? Cutie Marks are to blame for her unhappiness, so they must all be removed so nopony can ever leave her again. The Mane Six expose her as a brainwashing tyrant? Exploit TimeTravel to ruin their friendship before it ever begins, ButterflyOfDoom be dammned. Even post HeelFaceTurn Starlight has this problem, as her first instinct upon being told to socialize with other ponies involves things like magically compelling Big Macintosh to say everything that's on his mind and mind controlling the Mane Six sans Twilight.
** Chrysalis's Fatal Flaw is her {{Narcissis|t}}m and [[ControlFreak need for control]]. While a cunning strategist and ManipulativeBastard who's nearly conquered Equestria several times, she's shot herself in the hoof more than once by getting drunk on her apparent victory and congratulating herself before she's actually won, and her need to control is what exposes her to Twilight in her first appearance. [[spoiler:Her inability to accept she's wrong and change how she runs her hive ultimately costs her ''everything'' in her second appearance.]]
* ''WesternAnimation/TheOwlHouse'': Luz's major fatal flaw is her is [[DidntThinkthisThrough her inability to think in the long term]]. On Palisman Adoption Day, abandoned Palisman choose which students they go to based on what they want to do for the future; Luz does not get one because she doesn't know what to do for her future. And that's not even getting into all the times that she gets herself into trouble without putting any thought into how she's going to get out of it.
* On ''WesternAnimation/ReadyJetGo'', Sean's fatal flaw is that he fears cramped spaces, heights, and gets space-sick easily, but he must overcome these fears in time so he can achieve his dream of being an astronaut when gets older. He was also somewhat of a neurotic, overconfident perfectionist in the early episodes, but he gets better later on.
** Jet's fatal flaw is his impulsivity. He tends to act before thinking, and this has caused trouble for him and his friends a few times throughout the show. He is also terrible at keeping the secret that he is an alien.
* ''WesternAnimation/SamuraiJack'': The Fatal Flaw of the [[TykeBomb Daughters of Aku]] is their LackOfEmpathy. They were taught from an early age that needing help is weakness and deserving of punishment, though this also means that they ''won't'' protect each other when they're on the defensive.
** Jack's patience is legendary, but more often than not he allows his frustration to boil over with disastrous results. Specific incidents include getting so infuriated at a constant stream of bounty hunters that Aku was able to create an EvilKnockoff of him to fight, and [[spoiler: lashing out in a blind rage after Aku destroyed the last known time portal in existence and then mutated the sheep that had helped him find the portal. That last one cost him his sword and sent him into a 50 year HeroicBSOD.]]
** Aku has several flaws:
*** EvilCannotComprehendGood. Given that Aku is the AnthropomorphicPersonification of evil, it's only natural that he suffers from this. Many of his schemes fail because he has no understanding of the concept of good. This trope is why him sending Jack to the future backfired. He'd expected a world ruled by him would allow him to crush Jack effortlessly when he arrived. He never took into account that a hero arriving and successfully resisting him would trigger HopeSpringsEternal and start giving the oppressed masses someone to rally behind. And in the series finale, [[spoiler:his execution of Jack fails because he couldn't comprehend that rather than being crushed by this, the ones Jack inspired would come to his aid en masse.]] Later on in the same episode, [[spoiler:he finally meets his end because he never believed his daughter Ashi could free herself from his control, letting her use his powers he awakened in her to take Jack back to the past and kill him.]]
*** Additionally, other things that are lost on him are "respect" and "teamwork", as he has ChronicBackstabbingDisorder to the highest degree and has actually screwed himself over time and again because he cannot help but betray his allies in some form or another, even when he's trying really hard not to.
* In ''WesternAnimation/SheRaAndThePrincessesOfPower'':
** Catra's biggest problem is [[GreenEyedMonster an overwhelming sense of jealousy]] and [[NeverMyFault utter inability to take responsibility for her actions]]. Her obsession with control, the past, and her inability to understand the responsibility she holds in her own life all stem from being jealous of someone else. She's [[HisOwnWorstEnemy her own worst enemy]] because she regularly makes stupid decisions to show up other people in her life, and when repeatedly given the opportunity to change her ways kept rejecting her chances because she'd rather lash out for perceived slights and convince herself that it's ''everyone else'' who's making mistakes. [[spoiler: She eventually grows out of it when Double Trouble gives her a ''vicious'' TheReasonYouSuckSpeech pointing out that everyone she genuinely cared for is gone and it's all her fault because she kept mistreating people in a desperate effort to prove herself and drove them all away.]]
*** In the first season, despite having a flashback of all their good times as childhood friends, Catra still turns her back on Adora, leaving her to die. Catra does this because if Adora is gone, it will mean Shadow Weaver will have to favor Catra instead.
*** Throughout the third season, Catra consistently makes things worse for herself out of jealousy. [[spoiler: Catra lies that Entrapta is betraying the Horde, getting Entrapta sent to Beast Island. This actively hurts the Horde's plans, but Catra's jealousy over Entrapta getting close to Hordak means she doesn't care. Scorpia's suggestion that they live in peace in the wastes is ignored the second Catra believes Shadow Weaver joined up with Adora. Even in a reality where Adora offers Catra the chance to escape the Horde before becoming She-Ra, Catra still chooses to insist that Adora is abandoning her. Later in the same episode, Catra is willing to destroy the universe, herself included, just for the sake of beating Adora at ''something'']]. Each time, Catra is offered opportunities to change, but blames others for her own mistakes and lets her long-held grudges ruin her senses.
** Maybe not as fatal as Catra's, but Entrapta's flaw is her overwhelming curiosity, combined with a complete disregard for consequences. As long as she can learn something, it really doesn't matter what happens. [[spoiler:She does have her limits, refusing to perform an experiment that might destabilize the universe, but before that, she had destabilized the climate of an entire planet and was perfectly willing to open the door for an invading army, just because she might get the chance to learn from them.]]
** Hordak's biggest fatal flaw is tunnel vision. Hordak is so fixated on projects of immediate importance to him that he overlooks dangerous developments right under his nose. Notably, he failed to grasp the full implications of She-Ra's re-emergence, the power contained in her sword, or her ability to unite the Princess Alliance.
*** Another one of his fatal flaws is {{arrogance}}. His arrogant attitude toward, and outright abuse of subordinates such as Catra and Shadow Weaver contributes to their disaffection, which has disastrous consequences for him. His arrogance toward the "inconsequential" Adora/She-Ra blinds him to the real threat she poses to the Horde.
** Adora's biggest flaw is that she can be too controlling -- when she wants to keep someone safe, she instinctively tries to fence them in so they can't get hurt. It's a holdover from her abusive childhood, when [[AbusiveParent Shadow Weaver]] would torture Catra and tell Adora it was her fault for not keeping Catra under control. It does a real number on some of her most important relationships, especially since she doesn't really have the emotional intelligence to realize that she's doing it: Catra views Adora protecting her and telling her that she should [[HeelFaceTurn change sides]] to get away from Shadow Weaver as attempts to put her back in Adora's shadow, while Glimmer in Season 4 takes Adora's actions as attempts to usurp her authority.
** Glimmer's flaw is her sense of righteousness. In Season 1-3, she routinely goes against queen Angela's orders to do what she thinks is right, which sometimes works out and othertimes don't, but this flaw really starts becoming a problem in Season 4, when [[spoiler:Glimmer becomes queen of Brightmoon. She still feels that she's always right, but now she has the authority to steamroll any objections. When Adora and Bow both object to her course of action because they know it won't work and only make things worse, Glimmer pulls rank on them and goes through with it anyway.]]
* ''WesternAnimation/TheSimpsons'': Lisa's biggest flaw is her dependency on her status as the smart one. Whenever confronted with the possibility that [[AlwaysSomeoneBetter someone might be smarter or more skilled than her]], she loses it and often tries to sabotage them. When given the choice of being a NormalFishInATinyPond in second grade or moving up to a better, more challenging education, [[StatusQuoIsGod she stays in her small pond]] because she [[TheBGrade cannot tolerate less than stellar grades]].
* ''WesternAnimation/{{SpongeBob SquarePants}}'': Squidward is brought down by his hubris. [[ShrineToSelf His paintings and sculptures are pretentious and self-indulgent]], and [[DreadfulMusician his clarinet playing is atrocious,]] yet he's so convinced he's an artistic virtuoso that he puts no effort in improving himself. Whenever someone (usually [=SpongeBob=]) proves to be much more talented than him, he refuses to accept it and berates him for not respecting TrueArt. A {{Flashback}} reveals that he thought working at the Krusty Krab would be a mere interim until his artist career took off, and smugly laughed at the possibility that it wouldn't. No prizes for guessing where that got him.
* ''WesternAnimation/StevenUniverse'':
** Steven's main flaw is his self-sacrificing nature; he tries to take everyone's burdens on himself, even when it's obviously burning him out. This is made worse in ''WesternAnimation/StevenUniverseFuture''.
** Connie keeps secrets and assumes that other people's reactions would be more negative than they are.
** Lars has both severe social anxiety and self esteem issues, leading to a defeatist mentality and a JerkassFacade. His determination to seem as cool by others results in screwing up his relationships with Steven, Sadie and the local teens. [[spoiler:He gets better in Season 5 after a DisneyDeath and bonding with The Off-Colors.]]
** Pearl has absolutely ''no'' self-esteem and depends on her relationships with others to feel good about herself. For most of her life, she was dependent on her LadyAndKnight relationship with Rose, to the point where she couldn't accept her relationship with Greg or her decision to have Steven. [[spoiler: She later almost completely ruins her relationship with Garnet by lying to her in order to keep [[FusionDance Fusing]], since as a fusion with Garnet she got to feel Garnet's self-confidence.]]
** Amethyst also has no self-esteem, but in a different way. Her origin as a defective Gem from one of the Homeworld Kindergartens means that she thinks of herself as being a parasite on Earth, and she has little confidence in her own strength.
** Garnet is an odd case, since she's a Fusion and both Ruby and Sapphire have their own. Ruby's is her hot-headedness and singleminded focus on the present, to the point of not even trying to look for solutions to her problems. Sapphire's is her apathy and trust in her future vision; she is so invested in the future, she forgets that the problems she sees solved ''haven't been solved yet'', and need her to act to fix them.
** Rose Quartz had her CondescendingCompassion and [[InnocentlyInsensitive Innocent Insensitivity]]; while she really ''was'' an AllLovingHero, she had no idea how deep that particular rabbit hole went. She didn't understand that humans could love on equal terms with Gems until Greg confronted her, and she was particularly bad at understanding how others felt, especially towards her. [[spoiler: Some of this presumably came from being so isolated as Pink Diamond.]]
** Blue and Yellow Diamond have opposite flaws; Yellow Diamond represses her emotions to the point that they cause her to act irrationally when they get too much, while Blue Diamond lets her emotions distract her from both her duties and from finding peace. [[spoiler: White Diamond holds everyone to impossible standards of perfection, including herself.]]
** Pink Diamond's flaw was her immaturity. She was the [[NoRespectGuy No Respect Gem]] among the Diamonds, and her frustration led her to throwing tantrums to just get some attention from her sisters. [[spoiler: She later grew out of it, but into others -- see Rose's entry above.]]
* Two fatal flaws are exposed in an episode of ''WesternAnimation/TeamoSupremo''. Mr. Paulson admits to being too trusting. He tried to give his former lab assistant Crawford a second chance after he served his sentence for his villainous rampage as "the Gauntlet", [[TheFarmerAndTheViper only for Crawford to backstab Paulson and steal the Mega Gauntlets again.]] Paulson then reveals Crawford's flaw, [[RageBreakingPoint his temper]]. He joins the team in confronting the Gauntlet and taunts him until, in a fit of rage, he ''hands the Mega Gauntlets over to Teamo Supremo'' so he can [[LetsFightLikeGentlemen fight Paulson himself]].
* ''WesternAnimation/TeenTitans'':
** Robin 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.
** Brother Blood is a genius and master manipulator, his flaw being perfection and pride. Once Cyborg proves resistant to his mind control, Blood becomes ''obsessed'' with finding out why, this one man he cannot control leading him to take foolish risks and bringing him to the brink of madness, and eventually, defeat.
** Terra's is her inability to take responsibility for her actions, owing to being blamed for things that ''weren't'' her fault when her [[PowerIncontinence powers went out of control.]] This leads her to keeping secrets from the team, running away from her problems and being an easy target for [[BigBad Slade]] to manipulate.
* ''WesternAnimation/TotalDrama'': Every character has one that ends up biting them in the back at some point.
** Pride is actually a very common fatal flaw in Total Drama. [[AlphaBitch Heather]] and [[JerkJock Jo]] refuse to play nice because of it, and both are mostly disliked by their peers. [[DumbJock Lightning]] frequently makes bad decisions because of his arrogance, and it turns his team against him in season five. And then there’s [[{{Bishonen}} Justin,]] who has a tendency to limit his participation to avoid ruining his appearance. Topher thinks he can take over Chris’s role as host, and lets his team lose when he thinks he has. While Harold was never really done in by his, it generally did him no favors with his team. And while pride was arguably not Sugar’s biggest flaw, [[HoistByHisOwnPetard it was the one that got her eliminated in the end.]]
** Courtney's flaw is perfectionism. She expects others to follow her unquestioningly, gets dangerously angry when they don't, and is constantly trying to elevate her own social status. This has led to her downfall in every season she's in. Two other flaws that lead to her downfall are her need for control and greed.
*** [[ControlFreak Control]]. The reason Courtney has never made it to the final two despite being such an effective competitor is because winning is so important to her that she views other contestants as tools or pawns to further her own goals, rather than people. Unfortunately for her, she can't stop her "pawns" from using the show's most crucial weapon against her: the voting booth (and unlike Heather, she doesn't know how to manipulate people ''out'' of using it against her). Her own desire to win ultimately sealed her fate in ''All-Stars''.
*** {{Greed}}. Whenever Courtney has a choice between another person or the prize money, she will ''always'' choose the latter, no matter how important that person is to her (as Duncan, Gwen, and Scott can attest to). Not surprisingly, this has been the nail in the coffin for all of her relationships, romantic or platonic.
** Heather's fatal flaw was recklessness in the first season. Heather repeatedly commits actions throughout Island that not only manage to alienate everybody on her team, and ultimately, the entire cast, but are extremely shortsighted and bring her no long term benefit while only giving her short term advantages. One excellent example of this is reading Gwen's diary, as it managed to make her an eternal enemy in Gwen, didn't get her team any points, (and it's implied that had Heather actually performed ballet, it would have been enough to seal a Gopher victory), and nearly got her voted off. The only reason she makes it so far, especially after the merge, is either someone else is removed, or she gets invincibility. Unsurprisingly, her shortsighted decision making finally gets her eliminated in the final three.
** Alejandro's flaw is his narcissism. It works to his advantage because he can back up most of his boasting, which impresses the other cast members, even after his true nature as a ManipulativeBastard is revealed. Unfortunately for him, stoking his ego is a great way to get him to lower his guard, which Heather manages to exploit twice in a row. He also fails to consider the possibility that he might be outmatched or outwitted in any way, so he's left floundering when [[EvilerThanThou Mal]] brute forces him into submission and no one is willing to listen to him anymore.
** Sierra's flaw is her obsessive nature. Aside from her stalking of Cody, she idolizes [[BigBad Chris]] (and the show itself) leading her to trust him blindly.
** Dawn’s fatal flaw is her social ineptitude, which is ironic for an empath. Her lack of any concept of privacy had a tendency to unnerve her teammates, and as a result, they ended up trusting [[BigBad Scott]] over her.
** Noah's flaw is apathy. He won't work with his team to win, and generally doesn't care about anyone's feelings -- which, combined with his sharp tongue, led to him being voted off.
** Duncan’s rebellious nature got him eliminated twice, and the second time, [[spoiler:he got arrested for blowing up Chris’s mansion.]]
** [[HairTriggerTemper Eva’s]] fatal flaw is her temper. She has a tendency to react violently to the slightest of offenses, and was voted out twice for being unstable.
*** [[AxCrazy Scarlett]] had the same flaw, taken to murderous extremes. Yeah, [[HarmlessVillain Max]] was annoying, but she should have known [[spoiler:trying to hold her castmates for ransom]] wouldn’t work on Chris.
** [[FriendToAllLivingThings Ella]] has the fatal flaws of naïveté and lack of social awareness. She fails to recognize Sugar’s hatred of her, and annoys her into setting her up for elimination.
*** [[WeHardlyKnewYe Ezekiel and Staci]] both seem to have the same problem, but even more so. Ella annoyed one unscrupulous teammate. They offended/annoyed their entire teams.
** [[GentleGiant DJ’s]] flaw is cowardice. In seasons 1 and 3, he let his fears get the better of him, and was disqualified as a result.
* Mark Lily of ''WesternAnimation/UglyAmericans'' frequently gets into trouble with his lack of understanding of the various monsters of the world he lives in despite being a social worker, whether that be trying to treat them like humans or straight ignorance:
** He temporarily killed Leonard by snapping his wand in half because he didn't know it was Leonard's life force.
** He let a batboy out of its cage in an attempt to treat it with respect, unaware it was closer to a rabid animal than a person. It bites him on the penis, infecting him with its venom, and Grimes swoops in to kill it, aware of what was gonna happen.
** Mark nearly killed a young manbird by trying a DieOrFly moment both because he thought it was ready and because he didn't want to try and teach him the manbird language, which consists of [[ClusterFBomb all swearing]]. The second part also means the manbird, Albert, will never properly communicate with his kind. Albert's singing even causes his father to disown him on his deathbed.
** He nearly kills Randall, who was turned into a plant/zombie hybrid, by acquiescing to his demands for human brains, under the impression it was what Randall needed. Leonard points out it was closer to a baby demanding candy and Randall is dying of neglect.
** His lack of knowledge on demons almost cost him his soul in one episode when he unwittingly agreed to a demonic ceremony with Callie. A recurrent problem in their relationship is also that it is clear Mark has no idea what he signed up for.
* ''WesternAnimation/TheWeekenders'' has Carver, whose desperation to be cool often leads him to making terrible decisions.
* ''Franchise/WinnieThePooh'': In "123's", Roo's major flaw is the inability to count over 6, and asks his friends for help.
* 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]].

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.

** Catra's biggest problem is [[GreenEyedMonster an overwhelming sense of jealousy]]. Her obsession with control, the past, and her inability to understand the responsibility she holds in her own life all stem from being jealous of someone else. On numerous occasions, she's given the opportunity to change, and fails to do so because of perceived slights towards her.

* 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...

** Burr is too much of TheStoic, making Alexander think he is unscrupulous. Burr is actually quite emotional, but he also has terrible timing and a tendency to wait too long before making his move.

* ''Franchise/{{Superman}}'' and his ChronicHeroSyndrome can sometimes push him into borderline martyrdom. He's also far more secretive than he needs to be, and has a lot of trouble letting people into his life.

** ComicBook/{{Brainiac}}, another Superman foe, has ControlFreak tendencies, often having a VillainousBreakdown when things go south. As Superman points out, this is basically his biggest weakness. Due to his absolute need to be in control of everything, Brainiac pretty much always works alone (and his rare team-ups are guaranteed to end in backstabbing), with his only consistent 'allies' being either his machines or people under mind control. By contrast, Superman always has friends and allies backing him, often giving him the edge over the alien.
* ''ComicBook/{{Watchmen}}'': [[PrinciplesZealot Rorschach]] summed up his own fatal flaw quite nicely in one moment:

*** Barok van Zieks tends to lose his ability to think rationally when people he genuinely cares for are involved. [[spoiler: The reason he convicted Genshin Asogi as [[SerialKiller the Professor]] despite the obvious signs that it was a frame-up was because the ''other'' option was that his beloved older brother Klint was the Professor. Klint really ''was'' the Professor and Barok had all the necessary evidence to realize this... but he just couldn't bring himself to think his brother was a murderer.]]

* ''WesternAnimation/MiraculousLadybug'': The eponymous character's [[ATragedyofImpulsiveness impulsiveness]], which leads her to say or do things without considering what the consequences of her actions might be, particularly when Adrien is involved. This has not only driven a wedge between her and her friends, such as in ''Rogercop'', but it has also caused [[CreateYourOwnVillain a substantial number of akumatizations]] that otherwise could have been avoided, such as in ''Gamer''.

** Distrust is another repeat one. The defense lawyer Roger Hammond ruined his client Yanni Yogi's life because he never trusted his clients (and so forced the guy to plead [[InsanityDefense Not Guilty by Reason of Insanity]], when Yogi really ''was'' innocent), and [[spoiler: Matt Engarde manages to [[DickDastardlyStopsToCheat ruin his own case by trying to blackmail the assassain he hired]] (the assassain having treachery from clients as his BerserkButton) because, being a backstabbing sociopath himself, he didn't trust that the assassin wouldn't turn on him.]]

** [[spoiler: [[VisualNovel/PhoenixWrightAceAttorneyDualDestinies The phantom]] has Paranoia; they could have easily escaped the game scot-free with no one even knowing of their involvement, but they just ''had'' to get rid of anything that might remotely incriminate them... which of course put them in a position to get all their crimes exposed in front of a courtroom.

** The villain of ''Turnabout Time-Traveller'' is called a time traveller because his fatal flaw is an utter inability to move on from [[spoiler: his failure to save his fiancee Selena Sprocket]], which causes him to mastermind a murder plot specifically to hurt [[spoiler: Sorin, who he blames for Serena's death because Sorin caused a car crash that nearly killed both him and Serena, and Pierce's choice to save Sorin first cost Serena her life]].

** Distrust is another repeat one. The defense lawyer Roger Hammond ruined his client Yanni Yogi's life because he never trusted his clients (and so forced the guy to plead [[InsanityDefense Not Guilty by Reason of Insanity]], when Yogi really ''was'' innocent), and [[spoiler: Matt Engarde manages to [[DickDastardlyStopsToCheat ruin his own case by trying to blackmail the assassain he hired]] (the assassain having treachery from clients as his BerserkButton) because, being a backstabbing sociopath himself, he didn't trust that the assassain wouldn't turn on him.]]

* ''WesternAnimation/AvatarTheLastAirbender'':

* ''WesternAnimation/TheLegendOfKorra'':
** TheHero Korra nearly gets killed or depowered on several occasions by her aggressive and proud nature. She gets better, at least. Bolin, meanwhile, repeatedly gets himself into trouble through his trusting nature which stemmed from Mako's overprotective nature. Mako's inability to spit anything out or relax for four seconds never gets him into any worse trouble than a difficult breakup. It's really a blessing that Asami doesn't have this trope that it enables her to keep their group together. Lin Beifong has trouble letting go of old resentments that she ends up hurting others who aren't even part of her resentment like her niece Opal, not so dissimilar to Katara as mentioned above. Tenzin can be surprisingly naïve for a middle aged man and has to learn not to compare himself to his father.
** The villains: Fittingly for a SatanicArchetype, Vaatu's flaw is his {{Pride}} -- more specifically, his belief that mere humans could never pose a threat to a supremely powerful spirit such as himself. [[FallenHero Kuvira]]'s flaw is her utter devotion to her goal of a safe and unified Earth Empire. While this makes her a {{Determinator}}, it also gives her tunnel vision and sends her further and further into outright villain territory. She also adamantly [[NeverMyFault refuses to take responsibility for the consequences of her actions]], an issue she's had since childhood as revealed in the ''[[ComicBook/TheLegendOfKorraRuinsOfTheEmpire Ruins of the Empire]]'' comic.
** Raava, Vaatu's GoodCounterpart, suffered from a similar flaw as he did. When battling Vaatu, she dismissively told Wan not the meddle in their affairs, whereas Vaatu was smart enough to manipulate Wan into helping him. While she chided Wan for his mistake, she also contributed to that said mistake as well due of her dismissive nature preventing her to explain to the first Avatar why freeing Vaatu was a bad thing, which enabled the GodOfEvil to manipulate him.

** Fishy Boopkins' flaw is his [[ThePollyanna naïve, friendly nature.]] Boopkins is one of the few main characters who is unambiguously nice. It's his biggest strength, as he manages to befriend characters that the others would normally never have a chance of doing so (he proves instrumental in recruiting Axol), but it's also his biggest weakness as he's a HorribleJudgeOfCharacter, which leads to him [[UnwittingPawn being manipulated by people]] (Bob), keeping company that most people would find [[PoisonousFriend unsavory]] (Saiko, Bob) or straight up [[TheFarmerAndTheViper repaying his kindness with evil acts]] ([[spoiler: Waluigi, the Anime Cartel,]] [[RuleOfThree Bob]]). For better or worse, it's his most prominent character trait aside for his love for anime.

** Kotomine [[spoiler:is unable to find any joy or pleasure in anything good, and can only find satisfaction or happiness in the suffering of others. He struggled for a long time to deny this flaw, to work around it, or to correct it, even going so far as to marry and have a child. His only sadness upon her death was regret that he hadn't killed her himself. With the [[PoisonousFriend help of Gilgamesh]], he surrendered to his own need for evil.]]

** 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.''

* Wrestling/{{Edge}}'s fatal flaws were his overconfidence and HairTriggerTemper.
