History Main / FatalFlaw

* [[WebAnimation/{{RWBY}} Weiss's]] flaw is pride, which cripples her friendships and ability to work as part of a team.

* 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.

* In ''Manga/MagiLabyrinthOfMagic'', Hakuryuu's desire to avenge the murder of his father and two brothers is beginning to isolate him from the one person he wanted to protect the most and leading him down the path of depravity.
** Alibaba's lack of confidence, especially in the Balbadd arc, made him indecisive which in turn caused problems when he tried to stand up to his older brother the king of Balbadd.

* In ''Manga/MagiLabyrinthOfManga'', Hakuryuu's desire to avenge the murder of his father and two brothers is beginning to isolate him from the one person he wanted to protect the most and leading him down the path of depravity.

* In ''ComicBook/{{Watchmen}}'', [[BewareTheSuperman Rorschach]] summed his up himself at the end of the book:
-->'''Rorschach''': [[LittleNo No]]. Not even in the face of Armageddon. Never compromise.

** Charming leaps into danger without thought.

** Emma is too much of a doubter.

** Sidney's love for Regina.
** Jefferson's need to please his daughter.

* 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.

** 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.

*** 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.

* 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.

* ''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]].

* ''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.

* 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]].

* 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

** When he was young, Dumbledore had a whopping case of {{Pride}}, [[spoiler: planning to create a "new world" with [[ThoseWackyNazis Grindlewald]] 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.

* 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.

* {{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.

* Series/TwentyFour
** Jack Bauer's uncompromising sense of justice
** Tony Almeida's [[LoveMakesYouEvil love for Michelle Dessler]].
