* Fan Fiction in general whenever a villain is given a [[DracoInLeatherPants pair of leather pants.]]

[[AC: ''WesternAnimation/{{Ben 10}}'']]
* All the OriginalCharacters working with the villain in ''[[http://www.fanfiction.net/s/4267279/1/Hero-High-Sphinx-Academy Hero High: Sphinx Academy]] have their own FreudianExcuse. The main reason they follow him is because he was pretty much the only person that could see past that and treat them as people.

* The whole of Fanfic/CodeGeassMaoOfTheDeliverance could be seen as a version of this trope taken UpToEleven for Mao. Of course, it also shows FreudWasRight.

[[AC:[[{{Crossover}} Crossovers]]]]
* In the ''{{Fanfic/Housemates}}'' universe it's discussed that [[{{Film/Thor}} Thor]] and his buddies would play "very rough" with Loki when they were kids [[ValuesDissonance as in it would be considered abuse among Midguardian children.]]
* In ''[[FanFic/SovereignGFCOrigins Origins]]'', a ''MassEffect''[=/=]''StarWars''[[spoiler:[=/=]''[=Borderlands=]''[=/=]''[=Halo=]'']] MassiveMultiplayerCrossover, we have Jackie Jakobs, subjected to a TraumaCongaLine starting with ParentalAbandonment, continuing through RapeAsBackstory combined with a life as a StreetUrchin. Of course, this isn't all [[TheReveal shown]] right away as initially, all readers see is a RichBitch who's more than willing to [[ColdBloodedTorture torture]] the story's heroes.
* In ''Project Horizons'', a ''Fanfic/FalloutEquestria'' fanfic ([[RecursiveFanfiction a fanfic of a fanfic]]), most of the villains have these. This is lampshades several times, but the funniest is when Blackjack rejoices upon finding a villain who *doesn't* have one, because she wouldn't feel sorry about the ensuing fight.

* PlayedForLaughs in ''Fanfic/AllYouNeedIsLove'':
-->''"The Beyond Birthday case made so much more sense now, BB wasn't a megalomaniac he was [[FoeRomanceSubtext L's spurned and neglected lover.]] Clearly the jam was just the aftershock of being forced into sex with someone that looked vaguely like a crack head. And she had prevented him from burning himself alive, if she had to have sex with L she might have tried to burn herself alive too. Naomi noted to herself that perhaps it was a good time to go to L.A.'s prison and apologize to that poor madman."''
* In ''FanFic/ACharmedLife'' things are not as perfect in Light Yagami's life as he pretends them to be—he is a very unhappy person and he thinks of Ryuk as his first real friend. Of course he's still a mass murderer...
* [[Manga/DeathNote Light]] is given one in BackStory in ''FanFic/ConstantTemptation''- [[RonTheDeathEater His father]] and [[BrokenPedestal role-model growing up]] turned out to be a DirtyCop and [[PoliticallyIncorrectVillain raging homophobe]] who arranged the deaths of all Light's past {{Love Interest}}s. Light figured out that his father was behind the deaths and [[GuiltComplex blamed himself for it]] [[FailureToSaveMurder because he wasn't able to protect them.]] He came to the conclusion that there was no [[ArcWords justice]] in this world but no one should suffer as he did, he wished there was ''some way'' he could protect ''everyone''... [[StartOfDarkness and then Light found the Death Note]]...
* Done twice in ''FanFic/ACureForLove'', [[PlayingWithATrope downplayed both times.]] 1) There's the background of OriginalCharacter V: [[spoiler: [[RapeAsBackstory She was a victim of a human trafficking ring and had a child by rape]] when she was 12 (a child that would later be stolen from her by Wammy's House.) L discovered the human trafficking ring and also how V had arranged their deaths, and so recruited her to be an [[ProfessionalKiller assassin]] for Wammy's House-in other words she was so broken when they found her they decided that she was beyond fixing and just trained her to be a SerialKillerKiller. But because she is an assassin they wouldn't let her talk to her son or let him know she was his mother and still alive.]] Also there are hints that [[spoiler: she might have been in love with [[DeathByOriginStory A who committed suicide.]]]] 2) [[VillainProtagonist Light]] is given one in BackStory when L asks him why [[HatesEveryoneEqually he doesn't really seem to like people]]-- at a young age he noticed [[HumansAreBastards how shallow, stupid, and unjust people were.]] [[MaliciousSlander It was often gossiped about in their neighborhood]] that [[TheUglyGuysHotDaughter he looks nothing like his parents]]. Their gossiping brought his mother shame, so Light internalized that it was his fault (even though he knew it wasn't) and that there was something wrong with him. [[FromBadToWorse It gets worse from there.]]
-->'''Light''': [[PlayingWithATrope "It was a boring story, sorry if you were expecting some deep and meaningful tale of woe. My childhood was fairly uneventful.]] [[DisproportionateRetribution I suppose I get hung up on innocuous things]] [[ItsAllAboutMe which you don't want to hear about."]]
* Also invoked in ''FanFic/OfficePolitics'':
-->'''[[Manga/DeathNote L]]''' (to [[Manga/DeathNote Souichiro]]): Did you hug your son enough as a kid?
* ''{{FanFic/Solitude}}'' does this twice for Light. First [[BreakTheCutie he's broken]] by his [[{{Deconstruction}} "perfectly normal childhood" when he's not "perfectly normal"]] and it's later made worse when he [[spoiler: [[RapeAsBackstory was molested by one of his father's coworkers]]]] but he never reported it because he knew that [[StepfordSmiler was not what people expected of him.]]
* In ''Fanfic/ThoseWhoStandForNothingFallForAnything'' as a teenager L [[spoiler: was molested by his father's coworker and [[AbusiveParents his father]] [[UsefulNotes/VictimBlaming blamed L for it.]]]] Later it's revealed that Light [[spoiler: witnessed the assassination of his political mentor.]] Also B has been in love with L for as long as he's known him... and has been stuck in the friend-zone for as long as he's known him.

[[AC: ''Franchise/DisneyAnimatedCanon'']]
* Disney/TheLionKing fans just love using this trope on Scar and Zira. Usually comes in the form of an abusive childhood or the loss of a parent at a young age.

* [[spoiler: Vaticus, Ignatius and Riccio]] have their's revealed during the St. Galleria arc of FanFic/TheTaintedGrimoire.

* In ''FanFic/TheNewRetcons'' Elly's hatred of motorcycles stemmed from [[spoiler: being rejected by her first boyfriend and the father of her first child, who was an avid motorcycle rider.]] Her obsession with cleanliness [[spoiler: was caused by her grandmother calling her unclean after she had a child out of wedlock, a feeling made worse when her first marriage dissolved. That same incident caused her brother Phil to swear that he'd never have kids.]]

* [[http://www.fanfiction.net/s/6179989/1/# DEATHmatch]], by Shadow Crystal Mage, attempts to justify [[spoiler: Nekron's attempt to wipe out all life in Blackest Night]] by saying the paperwork had been getting him down

* In ''{{FanFic/Heir}}'' Draco Malfoy is regularly tortured by his father via the Cruciatus curse. Also there's Harry himself- in this fic his abusive childhood is played much more seriously and as a direct result he's now a dark lord in training. Then there's Voldemort-- [[spoiler: as a child Tom Riddle had a [[BreakTheCutie psychotic break]] when the other kids [[OrphanageOfFear at the orphanage]] killed his baby snake in front of him.]]
* ''FanFic/TheJadedEyesSeries'' is another fic where Harry's childhood is played much more seriously as it becomes his StartOfDarkness when he snaps and murders the Dursleys. Then he ends up in an OrphanageOfFear where he's regularly bullied by the other kids and has the scars to prove it. It gets worse when [[spoiler: Harry discovers that his parents are still alive and have a perfect little family and a little brother who was living a perfect life while he was living in that Hell.]]
* In ''[[http://www.fanfiction.net/s/8679289/10/Diagnosis Diagnosis]]'' Harry expressed his annoyance at this particular trope when telling Hermione about his lessons with Dumbledore sixth year.
-->...He made a point to mention to her that it was hinted that Riddle had been abused, and that his mum had bewitched his father who was a Muggle, and even that he was more than likely unloved and abused, but that it was no excuse for what he became. The abused aren't predestined to become the abusers, and it always hacked Harry off when people, including the Headmaster made it seem like it was some sort of excuse.

* Pyrrhon is given one in ''FanFic/KidIcarusUprisingTheNovelization'': he's sick and tired of always being ignored in favor of [[BigGood Palutena]], [[GaiasVengeance Viridi]], and even [[EveryoneHatesHades Hades]], and sees hijacking the Aurum as his chance to finally get some recognition.

* In Webcomic/KillLaKillAU, the reason as to why 8-year old Ryuuko is a delinquent seems to stem from maternal deprivation from being separated from her mother at two-years old and her anger and upset thereof of something she felt sad about, yet didn't know what it is, as well as the fact that no one would tell her.

* ''FanFic/MegaManDefenderOfTheHumanRace'' subverts this. While Dr. Wily does have an abusive father who colored his outlook on life, the story takes pains to show that Wily himself is a horrible man who deserves punishment.

[[AC:''Franchise/{{Metal Gear}}'']]
* ''FanFic/{{Stray}}'' discusses this - it's set in the ''Franchise/MetalGear'' universe, land of villains with unhappy childhoods, and at least two characters (including one of the protagonists) are former {{Tykebomb}}s. However, Adamska (one of the tykebombs in question) eventually rejects the idea that a person's essential nature can be changed by the actions of other people.

* Meimu Uchiha from Reincarnation Roulette by Silver Queen has some great reasons for being the cold hearted villain she is. Doesn't make her any less disturbingly chilling and cruel though.
* Parodied in [[https://www.fanfiction.net/s/5415242/1/Oh-Did-You-Have-a-Sob-Story-Too-Sasuke Oh, Did You Have a Sob Story Too, Sasuke?]]. Since every vilain (almost) have a FreudianExcuse in the manga, Naruto has trouble remembering them, or rather wich is whose, leading him to [[CrowingMomentOfFunny list all of them to Sasuke until he get it right]].

* ''Fanfic/ACrownOfStars'': Gendo abandoned his son because he was just as afraid of Shinji as Shinji was of him. He did not know how dealing with other people or relating to them, and his wife’s loss broke him completely. After hearing about it Shinji did not think it was good enough of an excuse… until he realized he was just like his father.
* ''Fanfic/AdviceAndTrust'': Chapter 8 examines how Gendo does everything he does because he is a broken man, utterly afraid of other people, that was completely obsessed with getting his deceased wife back.
* ''Fanfic/TheOneILoveIs'': Most of the story is narrated from Shinji's point of view, so Gendo is treated very unsympathetically most of time. The "Let the World Burn/One Dream at a Time" side-story explores his personality and motivations. Gendo is depicted as a pathetic, broken shell of a man always felt lonely and frightened of other people, thought nobody would ever love him because he was not worth it and fell utterly apart after his wife's death, sending his only son away because he was scared of Shinji and of hurting him.

[[AC: ''Manga/PandoraHearts'']]
* ''Fanfic/BeyondTheWindingRoad'': Edith beats the crap out of kids in her class, blatantly disrespects teachers and other authority figures, and throws other people's emotional baggage into arguments when she's losing control of them. But she's also suffering from some extreme ParentalNeglect and it's heavily implied she was both ostracized from the community due to her mother's previous scandalous actions and sexually harassed by the boys in her school (in her introductory chapter, some boys fill her locker with condoms, though the author never outright states what they are). Worse, those same teachers and authority figures were predisposed to find fault in her whenever she came to them due to her mother's [[ReallyGetsAround reputation]].

* In Fanfic/Gensokyo20XX, we have a rather non-villainous example in Yukari, in that it be a fairly safe assumption some of her issues she's had, especially wanting to have a child to such an extent that it tears her up inside and some issues with attachment (either would be described as "something to love, something to hold, occasionally scold, and something that would take away an intense pain"), seem to stem from being abandoned by her parents, to whom she referred to as "two large shitbags", when she was two.

* In ''Fanfic/YuGiOhForever'', several villainous characters have a Freudian Excuse for why they turned to the dark side. 1) Jan Shimizu, the BlackSheep of his family, recounts late in the story that his father, Ryou Bakura, frequently treated him with subtle contempt [[spoiler:because Jan's appearance reminded Ryou too much of the abusive spirit of the Millennium Ring]]. It led Jan to leave home and change his last name, to distance himself from the family, and led Ryou to declare IHaveNoSon concerning him. 2) Michael Bronte, a member of the JUDAS organization's QuirkyMinibossSquad, explains that the reason he joined the group was initially to exact revenge on his parents--specifically, his stepfather used to physically abuse him as a child, while his mother turned a blind eye. Present-day Michael is an AxCrazy [[SlasherSmile Slasher Smiler]] who enjoys perpetuating ColdBloodedTorture on his victims. 3) Angel Snow, a member of the Zodiac terrorist group, grew up with a drunken and physically abusive adopted father. TheDragon then liberated her from that home situation, and she jumped at the chance to give him her loyalty. 4) James Truesdale, another Zodiac member, has a particularly painful one that he hides behind a mask of [[TheStoic stoicism]] and [[TheResenter thinly-disguised contempt for his sister]] [[WellDoneSonGuy and father]]: [[spoiler:his mother died giving birth to his sister, and his father made him keep his grief hidden for the sake of the little girl. He [[VillainousBreakdown blows up spectacularly]] [[CallingTheOldManOut when he finally reveals his past and his repressed anger]]]].
