This is the story of her mind."
The Killer Rarityverse is a trilogy of novel-length My Little Pony: Friendship Is Magic fanfiction stories by BronyWriter that detail the life of Rarity as a violent serial killer and how that affects the ponies around her, particularly her her friends and family.The original story, The Secret Life of Rarity, is the book in the series that follows Rarity and her actions from the time she begins killing, and why, until the beginning events of its sequel. It is by far the most violent story in the entire series as it is the one that details Rarity's murders, leaving little to the imagination. Rarity's preferred method of murder is with the use of various sharp knives and she is quite skilled with them. Eventually though she begins to lose what little sanity she has left and she begins to betray even her own twisted set of morals. The story ends with her execution by lethal injection after she is finally caught by the royal guards.The sequel, The Public Life of Sweetie Belle picks up right where The Secret Life of Rarity leaves off but from Sweetie Belle's perspective. She is forced to deal with the fallout of Rarity's actions. Many ponies around town suspect that she will follow in the hoofsteps of her sister, despite the fact that she shows no desire to do so. The story spans about twenty-five years and results in Sweetie Belle eventually having a daughter out of wedlock named Joyous Blossom. Much like her mother, Blossom, as she is called, is under suspicion that she will follow in Rarity's hoofsteps but once again she shows no desire to do so, even when confronted with bullies.The final story in the trilogy, and the one that was completed not too long ago, is Broken Blossom and once again it picks up pretty much where the preceding book left off. Blossom is left alone to deal with the fallout that came from the ending of The Public Life of Sweetie Belle and it details her life under the watchful eyes of the Royal Sisters. The story ends with her being executed, and seeing Diamond Tiara, Fire Ruby and Golden Necklace in Paradise.Broken Blossom also has an alternate ending story, The Word is Fear, where Blossom was never executed and must struggle with Rarity taunting her from the dead, who wants her to become the next serial killer. which she does. She kills her psychologist, a janitor, and three guards at the prison she was at. The story's final chapters have Blossom murdered by Celestia, who is banished to the sun by Luna.A second alternate ending, A Shadow Hangs Overhead is in progress, splitting off from the main story during Rarity's first kill, and she is caught immediately.Ripples is a series of side-stories beginning after Rarity's execution, depicting the reactions of various ponies affected by her crimes.
The Secret Life of Rarity contains examples of:
Alas, Poor Villain: Rarity. Her defeat and execution made her suffer a vision of all the victims that died in her hands. Even before she was caught, she was sobbing and even realized what she had done, yet is unable to even control herself. When her friends found out about her secret, they were all shocked, yet felt horrible for her when they found out why she became this. Not to mention, as she was dying, she sang the lullaby that she used to sing to her sister, Sweetie Belle, when she was little.
Asshole Victim: Once she meets the Mane Six and becomes and Element of Harmony she decides to only kill ponies that she feels deserve to be killed. Over the course of the novel she kills series antagonists such as Gilda the Griffin, The Great and Powerful Trixie, and the Flim Flam Brothers to name a few.
Downer Ending: Surprisingly enough, Rarity's execution is one of the most heartbreaking moments in the story, and it doesn't help that it's preceded by Celestia disowning Twilight as her student for unwittingly allowing Rarity to continue killing.
Enfant Terrible: Rarity's first kills at the age of eight. By thirteen she has killed nine ponies, all while still living with her parents.
Et Tu, Brute?: Eventually ponies around her start to find out about her being a serial killer. None of them take it very well.
Knife Nut: Rarity to the point where she imports knives from outside Equestria.
Knight Templar: Slightly averted as Rarity frequently casually states that she's going to pony hell (Tartarus) but beyond that she feels that she's doing the community and her friends a favor by killing nasty ponies.
Lack of Empathy: Rarity for her victims. An example is when Trixie tells Rarity her back story and Rarity truly could not care less.
In fact, she at one point says that she is not insane, she just doesn't have any empathy.
Manipulative Bastard: Rarity will sometimes exemplify this to get her victims into Carousel Boutique so she can kill them.
Man of Wealth and Taste: Rarity's passion is fashion and when she's not splattered in blood, she insists upon looking her best at all times. Also, her gem finding spell means that she is set up for life.
Team Killer: Rarity has a vision of killing Twilight and even contemplates murdering Fluttershy
Torture Cellar: Rarity's basement is where she does the majority of her killing. She likes to decorate it with the hides, manes, and tails of memorable victims.
Tongue Trauma: When Rarity kills one of her victims, a tomato vendor named Scarlet Tomato, she forces her mouth open and begins cutting it up with a razor.
Tranquilizer Dart: Rarity's preferred method of getting her victims into her basement.
Vile Villain, Saccharine Show: Except for the beginning and the ending, the story takes place during the show to the point where Rarity decides to kill certain antagonists because of their actions in the specific episodes. The universe serial killer Rarity inhabits is essentially the one of the show itself.
What the Hell, Hero?: Princess Celestia calls Twilight out for keeping Rarity's crimes a secret and trying to rehabilitate her on her own - however good her intentions were, the fact remains that several ponies are dead because of her. Twilight ends up banished from Canterlot for the time being, and she will never again be Celestia's protégé.
Willing Suspension of Disbelief: Much like how the story takes place during the show, if you took out the trait of serial killer, the Rarity in the story would be almost exactly identical to the character in the show itself. That is often cited as one of the things that makes the fic so effective. You as the reader have a much harder time pretending that the Rarity in the story isn't the Rarity in the show.
Woobie, Destroyer of Worlds: Rarity. She starts because she was forced to commit an accidental self-defense murder and gets a taste for it. By the end of the story she hates that she has no power over her addiction and it's to the point where she doesn't even enjoy killing anymore. Not like she used to anyway.
Wouldn't Hurt a Child: Rarity claims this after she hits a certain age. Not that that stops her when the situation calls for it.
X Meets Y: The story has often been compared to the TV show Dexter.
You're Insane!: Rarity's victims say this so often she creates a poster to show her victims things they shouldn't bother saying down in her basement because she's 'heard it all before'.
The Public Life of Sweetie Belle contains examples of:
Adult Fear: Sweetie Belle fears that her daughter Blossom will turn out like Rarity.
Alone with the Psycho: Twilight finds herself on the receiving end of a psychotic Sweetie Belle and it almost costs her her life.
Beware the Nice Ones: Blossom is an extremely happy, friendly, and kind pony who never wants to hurt anybody and is absolutely terrified at the notion of becoming like her aunt. When she's pushed too far by Fire Ruby and Golden Necklace, she violently kills them both.
Bigger Bad: While Rarity doesn't exactly have any direct influence in either this or Broken Blossom due to being dead, her influence is still felt.
Bittersweet Ending: Neither Blossom nor Sweetie Belle (who took the fall for her daughter) is executed for the murders but Sweetie Belle's horn is surgically removed and she's sent to be institutionalized for the rest of her life.
I need to stop it, Twilight. I need to stop lying to myself about what kind of mare my sister really was. She was a serial killer, Twilight. She kidnapped, tortured, and murdered dozens of ponies. After her death I...I guess I still kind of saw her as a victim in all of this. I felt like I needed to protect her reputation, even if she might not have deserved it. Heck, she didn't deserve it. Not at all as a matter of fact.
Character Development: After nearly killing Twilight, Sweetie Belle finally realizes and comes to terms with the fact that her sister was an evil pony.
Dark Secret: Sweetie Belle definitely doesn't want Blossom to find out that her aunt was a serial killer and she especially doesn't want her (or anybody else for that matter) to find out that she participated in one of Rarity's kills and was even the one to inflict the fatal blow, albeit by mistake.
My God, What Have I Done?: Sweetie Belle defends herself from an assault by a mad parent of a foal she scared but instantly regrets it. Also, she straps Twilight down to a table and tells her that she's going to kill her but experiences this trope when Twilight dejectedly asks her to make it quick.
Took a Level in Jerkass: Diamond Tiara. She was cruel to Sweetie Belle in the show and the second chapter, really cruel, but she took it to a whole new level when she had her daughter put a newspaper article about Rarity in Blossom's schoolbook.
Alas, Poor Villain: Diamond Tiara. Right as she was about to kill Joyous Blossom, her conscience overpowered her and she let her go. Moments after, Joyous Blossom takes advantage of this and kills her and before Diamond Tiara dies, Joyous Blossom reveals to Diamond Tiara that she killed her child.
Demoted to Extra: Twilight Sparkle, while being a main character for much of The Secret Life of Rarity, and also a prominent character in The Public Life of Sweetie Belle almost never appears in the third story, which is somewhat surprising, given her relevance to the events that transpire.
Enemy Within: A spectral version of Rarity that appears in Blossom's dreams, and eventually starts conversing with her which is actually a manifestation of Blossom's latent murderous tendencies.
Even Evil Has Standards: As much as Diamond Tiara wanted to kill Joyous Blossom, when she had her strapped in a room, her conscience eventually got the better of her and she let Blossom go.
Face Death with Dignity: Subverted. surrounded by the Apples, Lilly, her parents and half-sister, she attempts to soothe Comet Blitz, telling her that she is ready to 'go to bed'- only to terrify her as Rarity appears to her and tries to convince her to kill the filly. She appears to snap, repeatedly refusing to kill Comet and yelling for Rarity to disappear. She eventually does- only for Blossom to find that her family has left, except for her mother, who is crying uncontrollably into Applebloom's arms.
Especially shocking when you realise that that was the last time her family ever saw her alive.
Good Father: Blossom's dad, who's more than willing to welcome his illegitimate child into the family (and only had a one night stand with Sweetie Belle because he was drunk).
Happily Adopted: Subverted with Blossom. She most certainly doesn't want to be in the care of the Royal Sisters.
He Who Fights Monsters: The head proctor of Blossom's entrance exam, willing to cause harm to a child because of what her aunt and, as far as the public believes, her mom did.
If You Kill Her, You Would Be Just Like Her: Diamond Tiara attempts to kill Joyous Blossom by kidnapping her. But, as she was about to kill her, her conscience overpowers her and, realizing that it would make no sense to Sweetie Belle's child just because Sweetie Belle killed her child (well actually, it was Joyous Blossom who did, but she didn't know that), releases her.
Ironic Echo: Diamond Tiara has her daughter plant a newspaper article about Rarity on Blossom's desk, but is torn apart when the tables are turned.
In chapter two of The Public Life of Sweetie Belle, Diamond Tiara says that Sweetie Belle should be glad that Rarity is dead causing Sweetie Belle to go berserk and she nearly kills her in the assault and it is only called off because Silver Spoon runs to get an authority figure. In chapter seven of Broken Blossom, Diamond Tiara once again does something cruel to Sweetie Belle with the same results: Sweetie Belle begins beating up Diamond Tiara and is only stopped because Silver Spoon ran to get an authority figure.
It Runs in the Family: Blossom has the white coat of her mother, aunt, and grandfather as well as Rarity's blue eyes and her mane is a combination of the colors of her mother and aunt. Oh, and all three of them have committed murder.
Mama Bear: Sweetie Belle when Diamond Tiara threatens Blossom.
Mercy Kill: After confessing to her ten-year old crimes, Joyous Blossom tells the Princesses that she not only deserves death but asks for it. She is still tortured constantly by her subconscious manifesting itself as Rarity, and wishes for her family to remember her as she was, and not as the insane, murderous wreck she fears becoming
Oh, Crap: Diamond Tiara is shocked when she found out that Joyous Blossom killed her child, before being killed by her right after she released her.
Joyous Blossom was shocked when her cousin found out about her dark secret.
Forgot About His Powers: So much could have been avoided if Blossom's horn had been removed (as was done to Sweetie Belle in the previous story) after Analytical Brain realised she could be a threat to herself or those around her.
Idiot Ball: Celestia issues a standing order for Blossom to be killed on sight without considering how Blossom, whose talent is colour changing to Master of Disguise levels, might exploit that.
