"Easy for a good girl to go bad, and once we gone, best believe that we've gone forever."
She is adorable, sweet, nice, good-hearted... your stereotypical good girl. Until that fateful day
. Abduction, murder, rape, any kind of violence. You name it. The nice, good girl goes through an event (or series of events) that changes her character and shapes her to the way she is now.
And now she's a bad, bad girl.
They come in various different flavors. Sometimes they're simply an Ice Queen
. Other times, they are worse. Many female villains tend to be good girls gone bad.

Anime and Manga
- Elfen Lied has Kaede, commonly known as Lucy. She was nice and sweet, until a group of orphans beat to death Lucy's puppy, the only being in the world she actually cared about. And they found out about it from a girl who pretended to be her friend, the first human she was beginning to trust. That's when her murder spree began, although it was put down eventually thanks to Kouta. However, after he lies about his cousin's gender and she finds out the truth, she's gone for good.
- Anna could be considered, but due to her being Affably Evil, it's doubtful. She does have a rough past, since her own father used her for experimentation and much, much worse, but she's not truly bad herself.
- Boa Hancock from One Piece, although she got better.
- Nami was one as well, until she was freed from Arlong.
- Robin, while she was a villain, also qualifies.
- Higurashi no Naku Koro ni gives us Miyo Takano, who was revealed to be the main villain of the series in Kai. Her actions speak for themselves, and all because the investigation of her grandfather was laughed at and treated as rubbish. Her horrible life before being found by him contributed as well.
- All the main females from this anime are this, actually, when commiting murder. Except for Rika, who is inmune to Hinamizawa Syndrome. Each one has an event at a respective arc that makes her snap.
- Rena in Tsumihoroboshi-hen after killing Ritsuko and Teppei.
- Shion in Meakashi-hen when Mion and Keiichi's relationship makes her remember that Satoshi's gone.
- Satoko in Tatarigoroshi-hen after seeing Rika dead in the shrine, and Keiichi in front of her. And an axe on his hands.
- Mion does not fall into this in the anime and manga, but in the visual novels it is implied that, in one of the worlds Rika was in, Mion went Yandere for Keiichi, going as far as to murder others to keep him for herself.
- Madam Red from Black Butler, after the death of Ciel's parents and meeting Grell. Although she does redeem a bit at her last moments, when she is unable to kill Ciel.
- Subverted by Elizabeth, who was a bad, kickass girl until she met Ciel and decided to remain a cute, good girl for him.
- Yuno Gasai from Mirai Nikki eventually qualifies, after we learn that her mother kept her in a cage for not living up to her expectations. And then she goes completely bad after killing both her parents. And it just went downhill from there.
- Hinata too; she was a nice girl until the Survival Game began, which made her become The Dragon so that she could live happily with her father once it was all over.
- And let's not forget about Ai, who was abandoned by her parents and taken into the Eighth's orphanage, but was bullied by other girls in high school, and later raped.
- Megumi from Shiki was a common schoolgirl... until, she met the Kirishikis. Then, when she comes back as a shiki, she becomes much more bad, almost reaching Yandere levels for Natsuno.
- Yuka Minase from 11eyes could be considered this, even if in the end she returns to her old persona, becoming the sweet girl she was in the beginning once again, she does have her bad moments.
- School Days is famous for this; Sekai starts off as the protagonist's best friend and a comical plucky girl, which she was until she gets pregnant of Makoto who, terrified that his secret lover could be carrying his child, leaves her for Kotonoha and orders Sekai to get an abortion. Needless to say, things do not end well.
- Not to mention Kotonoha, who is this ten times worse. She was possibly the nicest girl in the series; honest, pure and compassionate. And then she starts seeing Makoto, falling in love with him. But when he starts secretly having sex with Sekai, Kotonoha starts to break, completely breaking after Setsuna kisses Makoto right in front of her to let her know that their relationship was over. Not to mention she had seen Makoto and Sekai dancing at the couples dance the previous night, which caused Kotonoha an Heroic BSOD that lead to her being raped by Taisuke. The result is not pretty◊. You've been warned.
- In Naruto, we have Konan, who used to be a cheerful young girl... then things happen.
- Misa Amane from Death Note may or may not be a case of this. It's unclear which was the moment that made an Ax-Crazy Yandere out of her: the death of her parents when she was a little girl, or getting her hands on the Artifact of Doom mentioned in the title.
- There's also Belarus from Axis Powers Hetalia. We see her in her, Russia's and Ukraine's backstory as a cute little girl who clings to her brother and pouts to her older sister. And then, we see her now, as a scary girl in a frilly Elegant Gothic Lolita dress...
- In Deadman Wonderland, when we see Minatsuki's (Hummingbird) past before the earthquake, she comes around as a sweet, innocent girl who loved helping her mother out in her flower shop. Then, the earthquake came along, and she's trapped on the shop. What does her mother do? Grab a pot of flowers and left her to die. And that's when she became as we know her now.
- Batman Returns: Selina Kyle is usually portrayed as a criminal who grew up on the streets. Here she has a regular job and a home but hates her life and eventually snaps.
- Being pushed out of a window by your boss also helps.
- Both female protagonists in Bride Wars become bad girls after their weddings get booked on the same date. And since, to them, weddings are Serious Business, they each become obsessed with ruining the other one's great day.
- Charlie's Angels: The villain in the second movie is the former agent Madison Lee, who was an angel previous to the three protagonists and lost her path after leaving said position.
- Averted in The Bad Seed. Rhoda Penmark was never good; she's been evil literally from birth, and the mystery of why she's evil is part of the creepiness.
- Rachel from Animorphs. She starts the series as a confident, poised and assertive young woman who excels in academics and gymnastics alike. But three years of fighting a guerrilla war gradually brings out the Blood Knight within her, and by the end she's a straight-up Sociopathic Soldier.
- A Song of Ice and Fire has Cersei Lannister, enemy of the Starks and queen of Westeros. Back in her childhood memories (which we get from her POV chapters in the fourth book), Cersei behaved as a nice little lady as she was promised she'd be married to Prince Rhaegar. A visit to a psychic later told her that not only she wasn't going to marry the prince, but she was going to have three children, and they would all die before she did. Also, as she left the psychic, she most likely drowned her friend in a well. Cersei's paranoia for the prophecy (combined with not being able to get over Rhaegar) is what turns her into the Manipulative Bitch we know today. Well, that and Tywin.
- Notably, Cersei was not much of a 'good' girl even before the visit to the seer. From Jaime and Tyrion's recollections, she was bossy, selfish and cruel from an early age.
- Arya Stark can be seen as this. She went from a young noble girl who didn't want to be a lady to a little girl who has killed a lot of men, despite her very young age. Not to mention she's now on her way to become a magical assassin of sorts.
- Her mother Catelyn completely loses it after the death of Robb (plus, she assumed Arya, Bran and Rickon were all dead as well), and after her own death and resurrection, going on a killing spree against every Lannister and Frey on her way. So far, Sansa seems like the only Stark good girl left.
- That may not be so, as the fourth book implies that she might have to kill her cousin Robert, or at least allow him to be killed by Littlefinger.
Live Action TV
- Bela Talbot from Supernatural. Even if we don't exactly know whether she was good or bad before she made her deal with a demon, it was certainly implied that she was somewhat innocent... and being abused.
- Ruby qualifies as well. Before being the demon we know, who eventually betrayed the Winchester brothers, she was a human witch who lost her soul to the demon Tammi. The torture she underwent in hell, that eventually turned her into a demon as well, is responsable for making her a bad girl.
- Heroes gives us Niki Sanders, although in her case she didn't turn into a bad girl, she developed a second personality that was a bad girl. So, there was good girl Niki and bad girl Jessica. Jessica took control over Niki's body, though, so she counts.
- And then there's Elle Bishop, a bad girl as result of years of torture by her own father since she was eight.
- The future version of Claire Bennet we see in Season 3 counts as well.
- In Gossip Girl Jenny Humphrey, possibly the most innocent character of them all, is nearly raped and gradually transforms first into a bad girl and by season four is even something of a villain. She mostly learns her lesson though after loosing her virginity to Chuck, her own would-be rapist from before at the end of season three.
- Serena is a very bad girl who went very good.
- In the fourth season of Chuck Vivian Winterbottom, a sweet, naive character, is manipulated into following in her father's footsteps after being hurt by both him and the show's heroes. In the end her father himself is able to redeem her.
- Faith from Buffy the Vampire Slayer fits this trope perfectly, although she gets better after appearing in Angel and turning herself in to the police.
- Also, Willow after the death of Tara on the episode "Seeing Red".
- Inverted with Claire from Modern Family, who makes sure her daughter doesn't make the same mistakes she did.
- Regina Mills from Once Upon a Time is a clear example of this, after her mother killed Daniel, the man she truly loved, in order for Regina to marry the king.
- The final season of LOST reveals that Claire has become this. She becomes good again in the end, however.
- Subverted in "Last Whiff of Summer", the two-part fourth season premiere of The Middle. Sue realizes that even the negative attention her older brother gets is attention, and decides to start going bad to get some of that from her parents. However, the transgressions she comes up with—not wearing her headgear at night, wearing a red hair extension, and not taking her multivitamins—aren't really that serious. Double subverted by her parents not noticing or caring.
- Morgana from Merlin discovers she has magic in a kingdom where it's punishable by death, lives in terror of her guardian the king, tries to run away only to be brought back again, can't prevent her powers from manifesting, becomes estranged from all her friends, meets her half-sister who places her under a spell that causes all of Camelot to fall asleep, and is poisoned by a friend she trusted in order to break the enchantment. She comes back after a year's absence with a few bones to pick...
- Quinn from Glee becomes this in the beginning of the third season, due to the events at the end of the second season, complete with whole new look: pink-dyed hair, piercings and cigarette in hand, she is the complete opposite of her old self.
- Pretty Little Liars: Alison is strongly implied to be this prior to meeting CeCe. In one of the webisodes, Jason tells Cece that Ali was just a little girl until she came along and made her what she was prior to her disappearance.
- As of the season two finale, Mona fits this trope to a T.
- And Meredith. Dear God, Meredith.
- Subverted by Sara Tancredi from Prison Break, who was a good girl before she got hooked on drugs, as revealed through flashbacks dating prior to Lincoln's arrest. Her father even had to use his influence to prevent it from going on her record. It is only after she is unable to save a life due to being drugged at the time that she decides to straighten up and get over her addiction.
- On the second season, while she's on the run with Michael and Lincoln, she is classified as this again.
- In True Blood, Debbie after getting hooked on V (aka vampire blood). We also have Jessica, who's not evil or anything, but before being turned into a vampire she was a good girl who went to church and classes and obeyed everything her father told her, and now she's a blood-thirsty vampire so... you can see how she might fit in here.
- Invoked by Rihanna with her album Good Girl Gone Bad, which provides the page quote.
- Damara Megido from Homestuck was apparently fairly nice in the early stages, but following something of a bad breakup she went Ax-Crazy.
- White Mage from 8-Bit Theater tries to embrace this when (after talking to Fighter of all people) she starts to blame herself for all the damage done by the Light Warriors and her inability to do much good in the world. However, her greatest attempts at villainy are really just Poke the Poodle moments and Fighter (again) convinces her to switch alignments back to Lawful Good.
