"A child is born to innocence. A child is drawn towards good. Why then do so many among us go so horribly wrong? What makes some walk the path of darkness, while others choose the light? Is it will? Is it destiny? Can we ever hope to understand the force that shapes the soul?"
Nobody is born evil
(well, except maybe the Enfant Terrible
). Something usually happened to push a villain down the path to villainy
. And hey, mightn't that make an interesting story?
Thus, we have the Start of Darkness, a Prequel Dark and Troubled Past
where we find out how the main antagonist from the original story got to that point.
This, naturally, is especially common with Fallen Heroes
, who usually get a Downer Ending
where they lose faith in themselves and/or humanity. This will be especially poignant if they Used to Be a Sweet Kid
(see also: Freudian Excuse
Keep in mind that the reasons aren't always good ones
, if there is such a thing as a good reason for turning evil.
Much of the plot is often a Foregone Conclusion
, often ending in The Bad Guy Wins
or Pyrrhic Villainy
; many characters are Doomed by Canon
, which may require a full Kill 'em All
to explain why they don't show up in the original work. May include a Bloodbath Villain Origin
to signal the first emergence of the character's villainous side.
Badly executed, this can be a part of a Badass Decay
Please note that this is about prequels and flashbacks
that show a major villain's reasons for turning evil. If this is the subject of the main plot, you're watching a Protagonist Journey to Villain
Subtrope of Face-Heel Turn
, which is when a good guy turns bad. Contrast Diabolus Ex Nihilo
, when the villain's backstory is pointedly left absent.
The Trope Namer is The Order of the Stick
prequel Start of Darkness
(see "Webcomics"), whose title is itself referring to the 1899 Joseph Conrad novel Heart of Darkness
, which tells the story of the protagonist's journey down the Congo river to rescue the mysterious Mr. Kurtz, an experience that changed his entire outlook on life for the worse.
Needless to say, this being a Prequel trope: Spoilers Ahead!

Anime & Manga
- In YuYu Hakusho, the Big Bad antagonists in seasons one and two are shown to have become villainous due to major psychological trauma leading to crises of faith in their formerly-held ideals (the massacre of Toguro's students by a youkai and Sensui's exposure to the depravity of humanity and then the Black Chapter tape). And in both cases enough self-hatred to stage really stupid, selfish Thanatos Gambits.
- Mazinger Z: Hell's mind was already unstable and unsound cause his upbringing (he was abused by everybody when he was young, including his parents. Particularly her mother often spouted she never wanted having children and she would be better off without him; and she was not above of hiting him for no reason). However, when he found out the woman he loved was in love with another man Juzo Kabuto, future builder of Mazinger-Z and Kouji's grandfather, he... flipped out and attempted to murder his perceived rival. Shortly after he tried helping someone... and he got the crap beaten out of him for it. Later he was crawling back towards his home, bruised and blood-stained, muttering "Mediocre imbeciles! You don't deserve being alive! One day I'll purge the world off all of you! And then everybody will have kneel before me". When you heard his words and saw his utterly mad stare you realized he had snapped out completely and Dr. Hell had been born.
- Let's tell people had shunned him out of scorn before, but after that point they did it out of FEAR.
- The Rozen Maiden Ouvertüre OVA explores the start of Suigintou's fierce rivalry with Shinku and the source of her massive inferiority complex that motivated her to become the first season's Big Bad.
- The 8th and final Parallel Works video for Tengen Toppa Gurren Lagann is one of these for Lordgenome.
- "Two Father's Little Soldier Girls", the 21st episode of Black Lagoon contains a number of flashbacks to Balalaika's past detailing her childhood, service in Afghanistan, disillusionment with society and rise to power in Hotel Moscow.
- Axis Powers Hetalia
- Almost every Rave Master villain gets at least a chapter for this. Some are a little sad, some will leave you temporarily cheering for the villain (until you remember that every single one aims to wipe out all life as we know it).
- One episode of RahXephon presents the back-story of Makoto Isshiki, an Evil Albino who is a cold-hearted seducer and major jerk to everyone else. It shows him as a cute and kind boy who just wanted to find his parents. Then, one day he admitted to himself what he really was, and his flashback ends with him getting an Important Haircut and taking on his nasty personality.
- One Piece has Chapter 0, a special tie-in to the tenth movie. In it, we see Shiki and Gold Roger's rivalry, as well as the Flying Pirate's escape from Impel Down and his preparing for the movie's plot. Interspersed are scenes of people throughout the world, reacting to both Roger's death and Shiki's escape.
- To a lesser extent, the Fishman Island arc explains part of what made Arlong who he is.
- One episode in the second season of Ghost in the Shell: Stand Alone Complex focuses entirely on Kuzes' past, showing what motivated him to fight on the behalf of the people, even against the state.
- Ga Rei Zero is explicitly stated to be the Start Of Darkness of Yomi. Judging from what happen in the manga, this might also qualify as Kagura's Start Of Darkness.
- Elfen Lied. Sure, brats. Go ahead and beat to death the puppy of the shy, emotionally-repressed pink-haired girl with horns and force her to watch — she can't hurt you.
- Naruto has done this with many antagonists so far, and attempts to justify the Uchiha examples, by claiming that their powers take hold of them because they love too much:
- Deuteragonist Sasuke Uchiha witnessed his brother Itachi murder their parents, after murdering their entire clan. He then was subject to days of Mind Rape compressed into seconds, and a challenge to kill his brother when he's ready. None of this makes him "evil", so much as focused on killing his brother, a world-class criminal, on his own. After months of being shown up by his rival, Sasuke gets reminded by Itachi again that he's insignificant. He then follows Orochimaru, the series' first Big Bad, to gain the power to beat Itachi. After he finds out the truth about Itachi's backstory, that it was the clan itself that was evil and Itachi was just following orders, he begins to show signs of mental imbalance, playing into the hands of the new Big Bad manipulating him, Tobi, and he decides his best option is revenge on their entire home town.
- Gaara grew up believing his mother named him as a curse against everyone else, for her having to die in childbirth. His father had warriors and himself to keep Gaara in line, because of the demon sealed within him, which would be unleashed if he lost control of his emotions or even slept. As a small child, he believed that there was only one person who loved him, his maternal uncle Yashamaru. The betrayal of Yashamaru transformed him from an attention-starved waif to serial killer. He came around to the side of good once he realized what friendship was, long before any of the above was actually fixed, and years before it was all retconned to be a big misunderstanding, and his parents always loved him.
- When Sasuke "defeated" Orochimaru the manga briefly touched on Orochimaru's past, while the anime expounded on it. His deepest dream was to live long enough to meet his parents when they were reincarnated. Years of war and loss turned him cold and bitter until only the dream of living forever remained.
- Nagato lived in a state of constant war, as his homeland was the battleground for all the bigger countries' wars. For years, he was subtly manipulated and watched by Obito as Tobi, and Madara as Black Zetsu. Then, his parents were killed in front of him. Eventually, the death of his dear friend Yahiko and his subsequent crippling drove him to share his Pain with the rest of the world.
- Kakuzu was imprisioned and punished for failing to kill the First Hokage. As a result he steals the elders hearts and runs away.
- Kabuto grew up an orphan, but that didn't let him get down. However, he never really knew who he was meant to be. He was inspired to be a ninja by the first people to challenge him to grow in his natural talents, Orochimaru and Danzo. While on a mission for them, he was tricked by them into accidentally killing his foster mother, who in turn had failed to recognize him due to their brainwashing of her. After this happens he hits the Despair Event Horizon and Orochimaru was the only person around that was there for him at that point. He commits some good, and a lot of evil, actions for the rest of the series, but only comes into his own once Orochimaru dies and he no longer has any guidance or kindred spirit.
- Obito Uchiha, after some subtle mental influencing by Madara, witnessed first-hand the death of his childhood crush at the hands of the friend who vowed to protect her and became convinced the world he lived in was hell. He then decided to accept Madara's plan to create a better world by killing or brainwashing everyone in the world.
- Madara Uchiha lived through a time of warfare, like everyone else in his generation. Then, thanks to his best friend's work, which he attempted to co-opt and sabotage, things started getting better and he mostly got over the wars, like everyone else in his generation. Then this one time, he didn't get to be the top boss of the country, after he eavesdropped on a private conversation between his best friend and his best friend's brother, where he found out that not everyone liked him, because he was such a bully to other people, his own family, and the people they were supposed to be courting as allies. So instead of being happy for his friend who did get the job, he used an ancient stone detailing the world's constantly warring history to assume said friend's system would fail and justify his becoming the Big Bad and trying to brainwash or kill everyone in the world, despite that in no way saying he in particular should take any action. Ladies and gentlemen, your final villain.
- The flashback arc in both incarnations of Trigun seems at first to be the background for the highly mysterious lead, but it's even more about the Start Of Darkness for the Big Bad, his Evil Twin. In the anime version, the kid was always somewhat touched in the head, and one abusive crewman, combined with the awareness that the human race destroyed the Earth and are now looking for a new planet, push his pragmatism into Kill All Humans territory. In the manga...he has much better reason.
- His manga reason made Vash try to kill himself twice and laugh hysterically when he thought he'd accidentally killed Rem! And manga Knives Used to Be a Sweet Kid—more than Vash, even. Some of adult Vash's ideals are stuff Knives said as a kid.
- Legato also gets one of these, in the manga. Unusually, it has a very upbeat ending — because psychotically serving an Omnicidal Maniac who doesn't really give a damn about you is so much better than being raped to death by the guy who owns you. Knives didn't just spare him, he even asked his name! Weirdest Crowning Moment of Heartwarming ever. And nameless-boy-who-would-become-Legato goes stumbling after him naked and weeping for joy.
- Livio has one, too, although his is complicated by the fact that first he got a psychotic alternate personality, and then later he was acquired by the Eye of Michael and turned into a killing machine in his own right.
- Anime Wolfwood also gets one. Manga Wolfwood just gets back story snippets. But because the anime is Lighter and Fluffier, Wolfwood's philosophical position has a lot less pull there, so he needs a more clear-cut 'reason' to think the way he does.
- Romeo X Juliet practically drops it line for line with the episode "Darkness: The Origin", which gives Prince Montague a somewhat run-of-the-mill Freudian Excuse.
- 2007 adaptation of Skull Man features one for Black Ghost, Big Bad of Cyborg009
- Episode 11 of Last Exile: Fam, the Silver Wing shows the event that ended up shaping Luscinia Hafez into the series' Big Bad.
- Berserk Golden Age Arc serves as one for Griffith/Femto, villain who was previously seen once, right before the arc started.
- Pokémon: The Origin of Mewtwo is this to... ...guess who.
- Fate/Zero is one for Kotomine Kirei.
- Muteki Kanban Musume, being a Deconstructive Parody of the Shōnen Fighting Series, has this in the short "Another Kanban Musume" : Megumi has an extended Flash Back when she tells the story of how in her childhood she tricked a teacher into teaching her under a Training from Hell how to gain Improbable Aiming Skills so Megumi can defend herself against Miki Onimaru. The parody here is that Megumi is not a Classic Villain nor is Miki The Hero. They both are only the Schoolyard Bully All Grown Up and The Rival to each other. The deconstruction is that this story is not about Improbable Aiming Skills, because Miki always manages to Dodge the Bullet. Megumi is really talking about how she realized that she was weaker than Miki, and how she renounced attacking her directly and resorted to lying and scheming to fight her… only Megumi doesn’t realize that, because she is a Hypocrite.
- Subverted in episode 10 of Puella Magi Madoka Magica. It seems to be one of these for Homura, but instead, it ends up showing that she's far less villainous than she seems (all of her Anti-Hero antics are an attempt to prevent Madoka from dying and/or suffering a Fate Worse Than Death). Played straight for Kyoko in episode 7.
- The third movie ends with Homura descending into Witchhood and deciding to protect Madoka's happiness by erasing her free will note . She'd been willing to do evil things before, but this was the point where she became evil, and- despite knowing this- didn't care.
- The Unlimited Hyoubu Kyousuke, episodes 7-8, for the Villain Protagonist, Kyousuke. Sort of a weird case because the flashback is almost entirely upbeat-ish; most of the tragic stuff is Time Skipped over. Only the final push where the captain shoots Kyousuke because he was supposedly going to destroy the world, but the assassination attempt fails to kill him and turns him evil, is actually shown.
- In episode 15 of Guilty Crown Shu of all people has one of these. Hare is killed right in front of him (in his arms) because of something stupid and selfish done by Souta and his friends in order to prevent the creation of the Void Ranking System. After her death Shu gets Dull Eyes of Unhappiness and mounts Inori and forcibly removes her Void and procedes to chillingly emotionlessly systemetically rip to pieces the mechs attacking them. He then proceeds to go hysterical and begin pounding Souta's face in before being dragged off by Yahiro. His next words, coming from Shu of all people, hit the characters(and the audience) pretty hard:
: "I was wrong. Kindness is pointless. We have to separate the good from the trash. I'm going to become king." Heil Mein Shurer
- Death Note After Light realizes what he posses, he decides that he enjoys having the power to kill those he views as evil. He even jumps the gun and starts his God Complex after he finally meets Ryuk and tells him about his intentions.
- In Toriko, Midora starts to reminisce over his past during his battle with Ichiryu. The flashback chapters reveal how a nameless baby born to be fed to wild pigs eventually became one of the most powerful and dreaded beings on the planet.
- Yet another Start of Darkness for the Master in the Big Finish Doctor Who audio drama Master. Apparently, it all goes back to when he and the Doctor were at the Academy, and he killed an older boy who was tormenting them. This isn't what happened. The Doctor killed the boy and then made a deal with Death for the guilt to be transfered to his friend.
- The audio drama series I, Davros shows the early life of everyone's favourite Dalek creating Mad Scientist. Interesting in that he isn't given any Freudian Excuse, and you don't gain any sympathy for him, just understanding.
- The Batman Graphic Novel The Killing Joke is a Start of Darkness story for The Joker. Just one of several, in fact.
- The issue Mad Love of The Batman Adventures is also partially a Start of Darkness story, this time for Harley Quinn. It explains who she was and how she ended up with the Joker.
- A large portion of Gold Digger's 75th issue was dedicated to Gina and company discovering the origins of both Alfred Peachbody (who was less noble in his beginnings) and Dreadwing, who fits this trope to an absolute T. Though Dreadwing's origins are detailed as mentioned above, it's further fleshed out in the Dreadwing's Myomior special, which is essentially Dreadwing's past narrated by himself. Arguably effective despite the repetition, as the unbiased depictions of events from earlier serve to highlight the twisted perspective Dreadwing views his past through. It manages to make him sympathetic and tragic, while simultaneously keeping him a Magnificent Bastard in the present.
- The Saint of Killers miniseries, which explained how the titular killer became the Implacable Man he is in the series proper. When he first appears, we know he was already a killer in the Civil War, but not how he got that way. Part of the miniseries shows his softening and becoming a family man. However, after a delay due to ruffians led to his family dying of fever, he returned to his killing.
- Herr Starr, the Big Bad, has his own issue of this, as well, showing how he rose to the position that readers see him in. He gets a Pet the Dog moment and a legitimate claim to having been a good guy at one point — and quickly shows the predilections that make him such an outstanding villain for the rest of the series.
- Fantastic Four, Annual #2, showed the Start of Darkness for Doctor Doom. Reprised in a mini in recent years called "Books of Doom", with added hardcore edge.
- While the Knights of the Old Republic comic series is mostly Zayne Carrick's story, in its background it deals with the Jedi duo of "the Revanchist" and Alek, showing their gradual transformation into the Revan and Malak we see in the game. In fact, this trope is so pervasive that Zayne himself and his Master Lucien were speculated to be a past version of every Sith Lord from the two games at some point.
- The Judge Dredd supervillain Judge Death has his origin given in "Young Death — Boyhood of a Superfiend". This shows (with some incredibly black humour) how a nasty and psychopathic child develops into a monster that wipes out his whole world. (Although, to be fair, the reoffending rate is to all intents and purposes negligible.) Darkness hardly begins to describe it....
- In IDW's Transformers material, Megatron Origin details the origins of... guess who.
- Transformers: More than Meets the Eye: Has the Shadowplay arc, which is being told to a comatose Rung to help Jog his memory. It's about Orion Pax (Optimus Prime) fighting down the corrupt Pre-war senate who seek to kill a bunch of bots, with the help of a non-corrupt senator and ragtag police crew. At the very end of the arc it's revealed that it's the Senator's start of Darkness, taking the fall so Optimus and his partner get out, and having his emotions destroyed and appearance altered forever, and this was the story of how Shockwave came to be who he is now.
- The gradually unfolding back story of Winnowill and Two-Edge rather took over the second major arc of ElfQuest. We got to see exactly how and why both ended up such raging twisties.
- X-Men villain Magneto has a truly long and harrowing SOD that was revealed in snippets throughout the years following his debut and would be truly over-the-top if everything about it wasn't mostly grounded in reality. It's far too long to fully recount here, but let's just say that it isn't too surprising that someone who witnessed first hand the evils of Nazi Germany, the Holocaust, the Soviet Union, and Red Scare stricken America while losing his whole family, a girlfriend, a wife, and a daughter along the way as well as finding out he's a mutant in the Marvel Universe would end up a Well-Intentioned Extremist.
- After decades of speculation, First X-Men showed readers Sabretooth's start of darkness. While Victor Creed was never that nice a guy, what finally pushed him over the edge into full-blown villain territory was the death of his girlfriend Holo. Holo was a member of a ragtag rebel band of mutants that Wolverine and Creed had put together, and after a while, Creed wanted the two to throw a Screw This, I'm Outta Here! before the final fight to keep Holo safe, but she would not have it. Sure enough, she dies. What probably made it worse is that, while she was dying, she used her powers to show Creed the life they could've had, with the two growing old and happy together, before cutting the illusion to reveal that she was in fact mortally wounded. Creed ends up blaming Logan, and to this day, makes it a tradition to kill any woman Logan is involved with.
- "Tales of the (X) Corps" strips in Green Lantern and Green Lantern Corps show the Starts of Darkness of various Sinestro Corpsmen and Red Lanterns, as well as Agent Orange. Some of them have tragic pasts, others (including Larfleeze) just aren't very nice people.
- All Red Lanterns have tragic backstories—at the very least they were betrayed by their fellow gangmembers—because the red power comes from rage, hate, and resentment.
- Friday The 13th: Pamela's Tale by Wildstorm.
- Reverse Flash: Rebirth tells the origin story of Professor Zoom, the Silver Age Evil Counterpart of the Flash. The story manages to showcase, via time travel, both what a nutter he was, and what a nutter he became. Long story short — he was a child of the Bad Future where The Earth Is Never Doomed, so he kind of started... acting out.
- Captain Marvel: Black Adam's turn to darkness was explored in a trip to the past. He used to be a champion to his people called Mighty Adam and was every bit the hero. Then a supervillain killed his family. He hasn't been the same since. History repeated itself in 52.
- The My Little Pony comics' first annual details Sunset Shimmer's SOD, from her tutelage as Celestia's student, to her abandonment of the path of friendship for power.
- The Jackie Chan Adventures fic Queen Of All Oni, is all about Jade's Queen persona re-emerging, and her desire for power driving her further into the realm of dark magic.
- The Pony POV Series has the Origins arc, which shows the backstory of Celestia, Luna, and Discord, and therefore serves as the latter's Start Of Darkness. Discord was never quite right to begin with, as it's shown that the draconnequi were like the Shiva of The Multiverse, performing Cosmic Retcons in order to prevent worlds from ending, with Discord enjoying it far more than his siblings, who were only doing their jobs. That being said, in the grand scheme of things he was just a bully and a brat — until an act of defiance on Celestia's part triggered a series of events that not only led to Discord embracing his sadism, but began a war between the Alicorns and Draconnequi, during which he was further mentored in evil by the Fallen Alicorn Morning Star. When the war ended, Discord was reborn in Equestria as a mortal (along with Celestia and Luna) with no memory of his past existence, leading to him becoming an odd, but ultimately kind-hearted being... until his true personality resurfaced and consumed his good one. From that point on, he was the Big Bad from canon and the rest of the series. Oh, and bonus points, it's shown at the end of the arc that when the Princesses defeated and sealed him away, his last act was to plant the seeds of doubt that led to Luna becoming Nightmare Moon. So he's responsible for her Start Of Darkness too!
- We get to see Diamond Tiara's Start of Darkness occur as the story progresses, with the primary Break the Cutie process happening during the Mind Games arc. By the time it's done, Discord's succeeded in breaking her so fully that she goes Nightmare and becomes his Dragon.
- "Fading Futures" was a fan-made ending to the (at the time) unresolved Bad Future, that involved Twilight Sparkle becoming the vengeance-crazed Nightmare Purgatory and then having a Heel Realization. However, when the Bad Future was officially revisited in the Dark World Series, it was eventually revealed that the Bigger Bad is Purgatory's evolved form Paradox, at which point Alexwarlorn (the primary author) released an altered version of "Fading Futures" called "A Fading Future", edited so that there was no Heel Realization and showed Purgatory/Paradox starting her revenge plan, making it a proper SOD.
- Chrysalis' start of darkness is covered as an addendum during the short arc that followed the end of Dark World: back at the Dawn of Time, a younger and more Hot-Blooded Cadence became convinced that magic was inherently evil and tried to kill Amicitia (the Magician Alicorn) in order to prevent its existence. After Amicitia nearly killed Cadence in self defense, Cadence's Light of Existence went to live a mortal life to teach her how wrong she was, leaving behind her Shadow of Existence... which, against every rule of the POV universe, somehow clung to sentience and a sense of self through sheer force of will. Pandora was impressed enough by this that she helped the Shadow gain its own Light, turning it into Chrysalis, who was sent into the mortal world.
- And then there's her Origins Episode, which shows her childhood after being reborn and how she eventually became Queen of the Changelings by killing their previous Queen, Cocoon.
- In the Puella Magi Madoka Magica doujin, "I'm working at a mahou shoujo recruitment company, but I think I may be at my limit" by Momiji Mao (NSFW warning for ads, since the doujin in question is on Danbooru), Kyubey is a worker at a magical girl recruitment company and down on his luck, such that his boss is threatening to terminate him if he keeps dragging down the company. The only people who believe in him are his wife Kyuko, who is three months along with Kyubey's baby, and his work buddy Kyuzo, the only one in the workplace who knows he is trying his best. Bolstered by this, Kyubey works extra hard, even pulling all-nighters, and manages to get ten new magical girls into the fold. But then it's revealed that not only did Kyuzo screw Kyubey over by taking all the credit for his accomplishments, but when Kyubey calls Kyuzo up and demands an explanation for this shit, that's when he (and we) learn that this isn't even the half of how Kyuzo's betrayed him — Kyuzo is in bed with Kyuko when he gets the call, and it turns out that he's been banging her on the side for at least three months, because that kid that's three months along? It's not Kyubey's. With everything good in his life taken away from him in one fell swoop, Kyubey snaps and goes postal on everyone before burning his workplace down. He makes a resolution that the next time he meets someone, he should give them the same cruel lesson that he believes Kyuzo and everyone else were trying to teach him.
- We also see this trope in another Madoka fanfic, Stars Above a crossover with Lucky Star. Homura first explains the Start Of Darkness of her timeline's Kagami in Chapter 3, but we see in happen via a Whole Episode Flashback in Chapter 9.
- In Through A Diamond Sky, Clu is a Jerkass, but not the dog-kicker of the film. At the end of the story, he's turned the torture devices from the Resource Hog base into the "repurposing" racks and uses the captured Hogs as the first test subjects.
- It's also the fact that he was jealous of his creator when it came to Jordan, saw that the Isos could reproduce, and saw Kevin and Jordan being in awe of the new Iso child. Having Tron blow off his fears and scold him didn't help.
- There's a Tumblr roleplay that crosses over X-Men: First Class with the alluded-to-in-canon 1960s era of Watchmen, which means that Magneto and Mystique's fall to villainy is played out right alongside, and in some cases interactively with, Ozymandias and Rorschach's own slides into Anti-Villain status.
- Inner Demons is one for Twilight Sparkle, but the Queen of Darkness' legacy is revealed to go back further than that. The original Queen of Darkness was an Alicorn named Midnight who was spawned in Tartarus, but upon seeing the light and beauty of Equestria, fell in love with it and eventually became its benevolent queen. Then the denizens of Tartarus tracked her down and demanded that she become their ruler and destroy Equestria. This caused Midnight's subjects to betray her, which in turn caused her to become the Queen of Darkness and try to destroy her former kingdom, until the pony who would become known a the Master of Harmony rose up against her and destroyed her with the Elements of Harmony. With her last breath, Midnight swore to return and have her revenge, and eventually she was reincarnated as Twilight Sparkle, who in turn was therefore destined from birth to become the next Queen of Darkness.
- The sequels expanded on this a deal further. It turns out another reason Midnight fell was because after she rejected Tartarus, her subjects, egged on by a Stalker with a Crush, killed the pony she loved, and her former friend Vale turned on her for being a demon. Twilight Sparkle remembers some of this, and is still pissed off at Vale for it.
- The Nuptialverse has "Metamorphosis", which explains the origins of Queen Chrysalis. She was originally one of Commander Hurricane's chief lieutenants, but her refusal to make peace with the other tribes and personal thirst for power led to her being kicked out. She then made a deal with Discord to gain great power, which he twisted to make her the first changeling and his dragon. She and the changelings were sealed with him when the Princesses defeated him, and then kept sealed by him upon his release to be set free as a backup plan in case he was defeated again. Of course, Chrysalis has no intention of continuing to serve him.
- Transformers Mosaic: Gave one to Abraham Dante, in "Way to Fall." A man who sought Immortality and Power even at the cost of his own humanity. He made a deal with Skorponok for that immortality.
"And so little by little the monster inside his soul would wake up. Little by little he would change his outer appearance to match what his soul had gotten dark with: rage, hate, and fear..."
"That's the Story of a man... who wasn't."
- Shadows Awakening: Chapter 11 details The Phantom's origins — he was once a samurai named Kyosuke, who was the protege of the Emperor's High Shogun, but who grew unhappy with the fact that the Emperor is only ruler because of the supposed divine right of his ancestors, rather than any real power. Because of this, when he was sent to infiltrate the Brotherhood of Shadows (the dark wizards who created the Shadowkhan), they were able to convince him to join them, becoming their leader, the Dark Champion. He then led them on a conquest of Japan, until he was abandoned by Tarakudo, and struck down by his former master. With his dying breaths, his rage at Tarakudo's betrayal transformed his spirit into the Phantom.
- The Shadow Queen's journey From Nobody to Nightmare is told in two non-consecutive chapters of Yu Gi Oh! The Thousand Year Door: Redux. The protagonists hear the first part in Chapter 36 from a descendent of a survivor of her atrocities, and the Queen herself decides to tell them the rest later, in Chapter 42. It's a long, sad, tragic story that started with a poor beggar being neglected, losing her two brothers, and ending up making a Deal with the Devil after falling into a Despair Event Horizon.
- The MLP fic Shadows provides one for King Sombra. He not only Used to Be a Sweet Kid (Celestia's, in fact), but he actually wasn't all that different from Twilight, being a kindhearted academic with a close-knit circle of friends. However, watching his father Star Swirl the Bearded grow old and die, he became terrified by the thought of death, and obsessed with achieving immortality. This obsession led to him driving away his friends, creating the Alicorn Amulet to try and boost his power to god-like levels, and ultimately his Moral Event Horizon crossing of conquering the Crystal Empire.
- In Ace Combat: Wings of Unity, the Big Bad, Aurora Starlight, was intially a curious unicorn filly. When she heard about the alicorns and got additional information from Princess Celestia, things began to go downhill. Her attempts at gaining wings were met with Celestia's disaproval, she was banished from Equestria for life, because her experiments were perceived as dangerous. For the next 50 years, she was planning revenge against the princess she used to adore.
- Aviators' "Ashes" describes how the MLP villains Discord and King Sombra became evil.
- The first two chapters, as well as a chunk of Chapter 11, essentially illustrate Count Logan's rise in The End of Ends.
Films — Animation
- According to his backstory, the evil Toad from Flushed Away was once the pet toad of the Prince of England, but one day the Prince received a pet rat for his birthday and flushed the Toad down the toilet. As a result Toad actually developed a hatred against all rats and wanted to have them all drown when the sewers get flooded during a soccer game due to the audience all using the toilets all at once. Ironically, some of his henchmen are actually rats.
- In Kung Fu Panda, we get brief glimpses of Tai Lung's when Oogway refuses to give him the Dragon Scroll. Master Shifu was partly to blame for this as well, since he never properly disciplined Tai Lung, and instead continuously praised and encouraged him, which helped lead to his Face-Heel Turn.
- Shown in a prologue in The Incredibles on how Mr. Incredible giving Buddy, his #1 fan, the cold shoulder eventually turned him into Syndrome.

- In Wreck-It Ralph, there was once a character named Turbo, protagonist of the racing game TurboTime, who loved the attention he got from gamers when they played his game. When a newer racing game, Roadblasters, came to the arcade and took the gamers' attention away from him, he didn't take it well. He took it so poorly, in fact, that he left his own game and entered Roadblasters in an attempt to sabotage it. He succeeded, at a price: both TurboTime and Roadblasters were deemed permanently out-of-order, unplugged and removed from the arcade. Turbo's reckless actions were so shocking that a phrase was created to describe them: "going Turbo". It's actually through an explanation of the meaning of the phrase that the aforementioned events are shown in a flashback. It turns out that Turbo actually survived and went on to invade an even newer racing game by the name of Sugar Rush, forcing himself into the game with a disguise and a new name: "King Candy". Unfortunately, the game already had a playable royal by the name of Vanellope von Schweetz, but he soon fixed that little issue. ...So, yeah, he's definitely the Big Bad.

He grows up to get married and work in a grocery store, apparently not planning on a criminal career, until he loses his job to the nephew of the local mafia boss and, around the same time, is lured into his first robbery by a friend. Later, when the aforementioned boss demands a cut of the proceeds from the friends' now brisk trade in stolen goods, Vito decides to kill him instead and effectively replaces him in the neighborhood.

- The Han Solo Trilogy by A.C. Crispin features a character who appeared first in Dark Empire, the comic book series set years after the novels but released years earlier. In Dark Empire, readers learned that he was an old friend of Han's, and also that he was willing to throw away that friendship by leading Han into a trap just for the reward. Crispin shows us in her prequels what a good and heroic guy he used to be, and eventually what happened to change him: he was captured, tortured, and crippled for life.

Despite the fact that she was never interested in him that way, his romantic idealism spurred him on to duel her betrothed Brandon Stark for her hand, which resulted in Petyr nearly dying and getting sent packing back to his own poor home although that quite probably had more to do with the outcome of him being rejected and raped (whilst drunk and believing himself in bed with Cat, by her sister, Lysa, resulting in her pregnancy, which their father forces her to abort. In the present, Petyr is a full-on Magnificent Bastard and chessmaster, in control of both the Vale and Riverlands after having manipulated, married, and murdered Lysa, and has taken on Cat's lookalike daughter Sansa, herself a Broken Bird, as both protegé and potential love interest.
- Fëanor of The Silmarillion has his over the course of several years due to a combination of manipulation, jealousy and anger issues, but the single defining moment is when he lets his anger and jealousy for his brother Fingolfin get the better of him and puts his sword to Fingolfin's chest and threatens to kill him.

- There is quite a bit of debate among fans as to where Walter White's start of darkness began. Some say it was at the very beginning when he first decided to produce meth. Others argue that it was his decision to let Jane die as opposed to saving her. Many others argue that his descent to evil began long before the series' story started, particularly with his resentment and bitterness over leaving his former partners' business out of Pride, which eventually became a multi-billion dollar company. His disturbing obsession with the company (he checks their stocks every week), gives quite a bit of evidence to this.
- Barney in the first season episode "Game Night" of How I Met Your Mother. We learn how he evolved from a long-haired hippie guy into the Barnacle.
- The Master gets a some of this in the Doctor Who episode "The Sound of Drums". It's revealed he was driven insane during a procedure on Gallifrey of staring into the Untempered Schism, a gap in the fabric of reality which exposes the time vortex. This then expanded upon in "The End of Time", where it turns out Rassilon, Lord President of Gallifrey during the last days of the Time War, retroactively drove the Master insane on his own command to establish him as a link between Gallifrey inside the time-locked Time War and the tangible universe outside it.
- The episode "Six Months Ago" shows how Sylar first killed a man and stole his power.

When Gwendolyn Post tells her about it, you can clearly see the pain in her face. This winds up destroying her trust in them, which wound up having serious implications down the road.
- The books and comic books have reenacted Drusilla's Start Of Darkness at least twice. Since it involved Angelus murdering her family and torturing/raping her until she lost her mind, this is usually done to elaborate on Angelus' guilt.
- Drusilla got a flashback in "Becoming Part 2" as well as the episode "Dear Boy" on Angel showing her as a human the time Angel started stalking her.
- While Angel gets plenty of flashbacks on his spin-off series, the season 1 episode "The Prodigal" specifically shows his human life and eventual siring from Darla. Speaking of Darla, she gets an episode like this to herself in season 2.
- The Cold Case episode "The Woods" explores the background of a Serial Killer who made his debut earlier in the season.

- MacPherson used the Phoenix artifact to save his lover; by "dying" temporarily, he saw the afterlife, which from his point of view was nothing but darkness. He assumed this meant that there was nothing after life, and that all that matters is the now.
- H. G. Wells lost her daughter, and started seeing only the worst in people; when she was de-Bronzed in the present, she saw things had only gotten worse and was pushed straight into Omnicidal Maniac territory.
- Walter Sykes was corrupted as a child by an artifact that let him walk; when it was confiscated by Warehouse agents (specifically, Pete's mom), he became obsessed with getting it back and getting revenge on the Warehouse for taking it away.
- Season 4 turns out to be one long SOD for Artie as his Enemy Within (manifesting as a hallucination of Brother Adrian) slowly consumes him.
- Rumplestiltskin in Once Upon a Time: In order to prevent his son to be drafted into the ogre war, he gained magic powers by killing the Dark One.
- "The Stable Boy" does this for Regina. Her ambitious and cold-blooded mother wanted her to marry up, but she was in love with a stable boy. When Snow White, then an innocent child, tried to help Regina by letting the ambitious mama know her stepmother-to-be was with the stable boy... Well, let's just say someone's True Love ended up dead, and Snow White ended up on the wrong end of a vendetta.
- "The Miller's Daughter" showed how Cora became who she was. When she was a young woman, she was tripped by an immature Eva (Snow White's mother before she married Snow's father) who claimed Cora hurt her. The King of the land forced Cora to apologize on her knees or he wouldn't pay her for the flour. She would later use the emotions she felt here to channel her magic to spin gold.
- Smallville is this for Lex Luthor. To be more accurate, season five, Lexmas. By Season 7 he's become the megalomaniac we all know.
- Morgana Pendragon gets a similar treatment in Merlin though in terms of personality, she's more Magneto than Lex Luthor. By Season Three, she's ruthless and cold, by Season Four, she shows remorse, and becomes more human, though still a Well-Intentioned Extremist.
- Well, the above is probably the intent of the series, realistically all the According To The Writer and the difficulty of turning a one-scene villain from the myth into a six-season character that had to survive to the end, it plays more like she's just schizophrenic and her evil personality turns up whenever a coin comes up tails somewhere in the kingdom. Her intentions would have to be coherent for her to be a well-intentioned anything.
- Mordred counts as well. He's been in a total of three episodes although he is returning for series 5, and he's already got a Freudian Excuse, budding sociopathic tendencies, and become way too willing to kill people for a child who grew up with pacifists and can't be more than 9.
- Spartacus: Gods of the Arena shows how Batiatus and Lucretia's ambitions led them to compromise their morals and become the utterly corrupt Manipulative Bastards they are in Blood and Sand.
- Season 1 of Carnivŕle delves heavily into Brother Justin's Start Of Darkness,as he develops from a compassionate and deeply moral laypriest into (at the very least) an unrepentant demon. It doesn't help that this was his bloodline and his sister murdered a bunch of orphans to engineer a personal tragedy for him.
- Person of Interest
- For Carl Elias, it was his Mafia boss father killing his mother, and then trying to kill Elias.
- For Samantha Groves (super-hacker "Root"), it was when her childhood friend was murdered and an adult she respected covered up for the killer. One of her first forays into hacking was done to visit Laser-Guided Karma on the killer.
- For Peter Collier, it was having his brother detained without charges and Driven to Suicide because a man he knew from his Alcoholics Anonymous meetings resembled a terrorist recruiter, followed by the officials responsible never getting punished.
- In a series that acts as a reimagining/prequel to a show about a ruthless women's prison and the top dog that rules it, this is almost inevitable, but in Season 2 Episode 1 we finally see it. Bea overcomes her drug dependency, but takes a final sedative so she can visit her murdered daughter, Debbie, one last time in a hallucination. She says her goodbyes and assures Debbie that she has a new purpose now. Then she stares down Debbie's murderer as the warm light of the idyllic scene is replaced with the cold green-gray of prison and says, "I'm gonna kill the fucker."
- The BIONICLE web-serial Mutran Chronicles and a scene from the book Swamp of Secrets reveal just why the formerly benevolent Brotherhood of Makuta turned against the Matoran Universe — it was because the peoples of the universe all attributed their efforts to preserve the balance of things to Mata Nui, and shunned them for being affiliated with the element of shadow. They got fed up with this. The comic Rise and Fall of the Skrall also details why the titular race wanted to overrun the desert region of Bara Magna along with its locals — they were driven out of their home-realm by robot assassins, and needed the space to fight back. Although it's to be assumed that being mean has always been their way.
- There have been several in-character ones over the years. It can be argued that Randy Orton's slow descent from the suave Legend Killer to the sadistic Viper was a result of his ousting from Evolution, something he never got over. Evolution played a major part in Randy's character and actions, being the reason for his hatred for Triple H, extending all the way to 2009, four years after the stable had fully dissolved, and yet at the same time a blueprint for Randy's own power stable Legacy. It's also pointed to as the main reason why Randy had gone kayfabe-insane in 2009. The event had such an effect on him that one could argue that it defines his entire career. Only recently has he managed to get over it.
- The New World of Darkness games all have a mechanic that encourages this trope for players: as the players sin or make immoral or counterproductive choices, they "degenerate", making future choices of slightly greater depravity and further degeneration easier and more likely. Each degeneration can also give a character a minor derangement such as a phobia or narcissistic tendencies, which can force further sins even if the player doesn't want to do so.
- Fits this trope because at the bottom of the scale the player becomes so irrationally self-centered and evil that they cannot be played and become an NPC. What kind of monster depends on the game: for mortals, you become a Serial Killer, werewolves become a movie-style wolf-man that hunts humans for fun, changelings become completely unable to tell imagination from reality, vampires become ravening blood-crazed beasts, and mages turn everything in their area of effect into a Cthulhu Mythos story.
- Metal Gear Solid 3: Snake Eater featured Naked Snake, who would later become Big Boss from the very first Metal Gear, in his US military operative days. Instead of being the traditional Bond Villain archetype he'd been in the previous game - or even the wise but guilty character his son was - he was a highly energetic, lovable dork. While certainly capable of wiping out enemies with the best of them, Big Boss seemed to prefer spending his time playfully messing with the heads of his medic and tech. Unfortunately, being forced to kill your own Mentor by an Ancient Conspiracy so that said conspiracy can take over first your country and then the world can change and disillusion a man.
- Super Robot Wars Original Generation Gaiden features the Start of Darkness of one of MX's Big Bad Albero Esto. It was only mentioned several times in MX, but in OG Gaiden, it's... rather full-blown and detailed.
- In Alpha Gaiden, Char's Face-Heel Turn (since Char's Counterattack is part of Alpha 2) makes even more sense then it's UC Gundam verse reasons. During the course of the plot, he watches humanity keeping picking the Too Dumb to Live options and the horrifying results, and this disillusions and pisses him off enough to decide a Colony Drop is actually a good idea.
- Sengoku Basara 2 Heroes features a Gaiden story for Maeda Keiji, which in fact was a Start of Darkness for a villain in the actual game, Toyotomi Hideyoshi. Hideyoshi starts out as a normal man, joining Keiji in pranks here and there, until he encounters Matsunaga Hisahide, who proceeds to humiliate him, and this causes him to become drunk with power, leaving Keiji and doing a lot of atrocities later on.
- The Mass Effect novel Revelation serves as a Start of Darkness for Saren, showing how he came to be the villain in the videogame....though in the novel itself, he's already an extreme Knight Templar.
- The comic Mass Effect: Evolution is one for The Illusive Man and Cerberus.
- About one third of Crisis Core is spent on telling us how Sephiroth became the Magnificent Bastard and One-Winged Angel he is in Final Fantasy VII. Including remaking Cloud's flashback scenes from the original game to the actual moment he snapped, also a Start Of Darkness in their own right. This took advantage of advances in animation and allowed for Cloud's serious amnesia problem. (Also the Epileptic Trees spawned when he had dialogue right for a scene he was not actually present for. Some fans believe his delusion of Zack-ness was largely caused by some kind of Hojo-induced memory transfer.)
- The game proved that he didn't suffer a sudden sanity loss, but rather more of a long line of betrayals that started as early as Gast's death and ended with the very facts of his own existence, which overall is both more believable (even allowing for Jenova's clear ability to mess with his brain) and more tragic. Due to Crisis Core we know that he had lost absolutely everything by the time this happened.
- His Start Of Darkness could be pinned at conception, at the moment he broke, or just described as 'his whole damn life.' The man was born one of Hojo's experiments. Their suffering has been unquestioned more or less since Hojo was introduced. Though he still had just enough innocence left during that fateful practice duel that events afterward could almost be labeled 'Break the Cutie'.
- Prince Luca Blight from Suikoden II had his after his family was ambushed by bandits in one of their official travels. He and his father managed to escape, but his mother wasn't so lucky. Luca wanted to go back for her but his father said that he couldn't risk his life as the King. His mother was rescued shortly after, but she didn't return to the castle. Several months later, Luca managed to find out where she was and quickly escaped from the castle in order to meet her. He had a arduous journey, and a man took his horse in exchange for a pear and some water (Luca didn't want to eat the wild berries or drink the muddy water he found in the way). Upon finally meeting his mother, she started to scream and rip her hair out when Luca came close. One of their aids explained that she was brutally raped by the bandits and got pregnant, as well as going completely insane and unable to stand near men. Luca then snapped. He went back to the castle, but not before meeting the man who took his horse, who he murdered with joy. He was also lucky enough to find a small village along the way, and found that the bandits, as well as his mother's rapist, were sheltered in a house there. He stormed inside the hut and caught everyone off-guard, murdering everyone. When he found the rapist, he tortured and killed him gruesomely. When he returned to the castle, two things were permanently scarred on his mind: the disgust for people and the pleasure he got when killing. Thus, Luca Blight, who causes a war for the sole reason of having an excuse to kill people by the thousands.

- Araya wants to take over Ryougi's body because he wants to reach Akasha, so all the meaningless deaths would at least have a reason and cease to be meaningless. ect.
- In Live A Live, the hidden Medieval Chapter explains just who and what "Odio" is, and what made him into the demon of hatred influencing the various end bosses. It starts the young, heroic, Knight in Shining Armor Oersted on a fairly formula "Save the princess from a demon" plot, but... well, to say it all goes to hell about halfway through would be an understatement. By chapter's end, everyone in the kingdom believes Oersted to be the real demon (over something that was an accident, not that they saw that part of it), everyone who believed in him is either dead, or being "protected" from him, his best friend is revealed to be the one who ruined his life, and the princess declares her own hatred for him after he duels said traitorous friend to the death, and then commits suicide. Oersted is left with absolutely nothing. He then proceeds to just plain snap, and decides that if the world is so insistent that he is a demon, then a demon is exactly what he will be.
- Dragon Fable's Fire War is a Start Of Darkness for Drakonnan. Once Yulgar's apprentice, Konnan called upon the hero to stop the rampage of the red dragon Akriloth upon his home village. But despite the hero's best efforts and the powers of the hero's recently acquired dragon, they were no match for Akriloth and the power of the Fire Orb. Akriloth, instead of finishing the hero, sadistically made them watch as he burned the village to the ground, killing Konnan's family. Konnan blamed the hero for failing to save them and when the evil pyromancer Xan got his hooks into him, this would turn into a desire for revenge that would soon threaten the entire land of Lore.
- In the 1st Degree has James Tobin charged with grand theft and murder. There are indications in the interrogation tapes that the chain of events leading up to the events in the game go back to when Tobin and his wife Helen divorced. He apparently took it hard and just went on a steady downward spiral after that.
- Baten Kaitos Origins shows how Geldoblame came to be in control of The Empire, and how he went from Verus' prissy Yes-Man to a megalomaniacal Evil Overlord.
- As seen in a flashback, the death of Sophia in Xenogears was the Start Of Darkness for Krelian and Grahf.
- Resident Evil: The Darkside Chronicles acted as the Start Of Darkness for Jack Krauser.
- Kingdom Hearts Dream Drop Distance gives us the Start Of Darkness for series Big Bad Xehanort. What drove this man down his path of villainy? His Heartless went back in time and showed his younger self all of the evil acts he would do, even bringing him to the future to help them out. Even though he would forget what he saw and do, the actions he would take are now engraved in his heart. Xehanort isn't just happy messing around with the heroes- even his youth is fair game!

- In Sonic Adventure 2, Maria's death at the hands of G.U.N. was this to Shadow and was his main motivation for wanting to destroy the Earth.
- Fate/Zero is mostly a retelling of the Fourth Grail War, making it the prequel of Fate/stay night. In it, Kotomine is still more or less a good guy, though all his mental issues are still present. While the war is going on and Servants are going down, Gilgamesh is needling Kotomine towards realizing what he is and descending into villainy.
- About one-third of the Matsuribayashi chapter of Higurashi: When They Cry is spent giving Nurse Takano one of these.
- Shion gets one herself during the Meakashi chapter (takes about 2 episodes in the anime, culminating with the "distinguishment" incident). The events happen in every arc (having taken place one year before the story begins, but whether the events "detonate" depends on the arc.
- In The Inexplicable Adventures of Bob!, Fructose Riboflavin has been the greatest criminal in the Nemesite Empire for the better part of two thousand years. But he Used to Be a Sweet Kid. Then his dad died...
- MAG ISA — The villains in this comic had miserable lives before they became villains.
- The Trope Namer — admittedly more recent than most of the other examples here, but it's still a pretty cool title — is Start of Darkness, prequel to The Order of the Stick detailing Evil Overlord Xykon and his Dragon Redcloak's past. Xykon, unlike most, is astonishingly evil from the get-go. We get to see him become more evil... but more importantly, a lot more competent. Redcloak is a whole other story.
- The comic's author and illustrator, Rich Burlew, said in the Introduction that the greatest challenge of Start of Darkness was to tell Xykon's backstory without making him even slightly sympathetic. He solves this problem by making Xykon's every appearance push him farther beyond the Moral Event Horizon.
: ... [Xykon]'s completely and wholly unapologetically evil, but more to the point, he's kind of a dick
- The very first page of the book might have been teasing at it: Xykon is shown as someone who might come off as sympathetic for the first three or so panels, but revealed to be already evil before the page is over — at the age of four. And yet, Burlew does give him one simple human, if not quite redeeming, quality that makes his final descent, if not sympathetic, at least understandable. After being turned into an undead creature, he loses his ability to enjoy simple pleasures such as the taste of coffee. And then brutally murders the diner waitress because of it.
- Burlew makes a point of not giving away Belkar's backstory in On the Origins of PCs (and the Belkar backstory comic for Kickstarter donors) for similar reasons, wanting the character to remain completely, unapologetically and unmistakably evil. Although, also to keep him funny. Evil isn't funny when it has a tragic backstory, just pitiable. Belkar does end up revealing a sob story in his childhood in the main comic... Entirely made up, it turns out, spun in order to gain roleplaying XP.
- In Sinfest, we get Baby Blue's unhappy past. (We see nothing of why she got those F's.)
- In Act 6 of Homestuck we learn Lord English's origin. He was a boy called Caliborn who dropped himself in a "dead" session of Sburb (the Absurdly High-Stakes Game the characters are playing) than slowly worked to become more and more powerful until he ultimately became a full-blown Eldritch Abomination. Also subverted in that we learn he was a scumbag even before he became Lord English. If anything he simply transformed himself from a Harmless Villain into The Juggernaut.
- The flashback chapters of Evil Plan show how Stanley turned from an idealistic inventor into Urbane City's first super villain. He found out his accountants were selling his inventions to super villains, he gained telekenesis via a self-experiment and accidentally killed his best friend trying to recreate it. The final scraps of his spirit crushed by trying to earn an honest buck as a bank teller, from there on he turned his company into a legitimate front, started building super gadgets, hired some minions and an engineer, opening the doors to the main story.
- The Spoony Experiment spoofs this in its April Fools Day review of the original Final Fantasy. The Spoony One was driven insane trying to comprehend the game's time travel plot and became determined to invent his own method of time travel to stop the series from being made, ultimately causing his own time paradox by his future self appearing and presenting him with the technology fully formed. Along with a rather neat bit of acting, with Noah making a seamless transition from Spoony to Insano before our eyes.
- The version two finale of Mega64 reveals how Dr. Poque became the Mad Scientist he is today.
