After a tragic accident, Buttercup is left horribly scarred on her face and arms and suffering from a damaged eye. This leads the citizens of Townsville to ostracize her. Because of this she grows into her teenage years to be much more bitter, resenting the ungrateful people she's defending every day and her sisters, who get all the love and fame while she has to deal with daily doses of mockery, bullying and disgust.
One day she snaps.
Willingly entering a path of villainy, Buttercup teams up with Mojo Jojo, to tear down the town and kill her sisters, rejecting her old name and becoming Jojo Jr.
Clearly a Dark Fic, with graphic describtions of violence and a pretty large kill count. Has a sequel, dealing with a new generation of Powerpuffs, one of whom might be on the same path to villainy Buttercup once walked.
- A-Cup Angst: Comes up only once, but Buttercup describes her breasts as nonexistent.
- The Bad Guy Wins: The first story ends wih Jojo taking over Townsville and starting her campaign of world conquest.
- Bad Powers, Bad People: Turns out that Buttercup never manifested a special power like her sisters because hers is dependent on hatred and a desire to kill, which she never felt before turning evil.
- Vampiric Draining: What said power is. Only on a boderline WMD level.
- Big-Bad Ensemble: Between Mojo and Jojo, and Him, who controls the society of supervillains. They win.
- Body Surf: Turns out Him is capable of this. When his body is killed by Buttercup, Princess and Mojo, he eventually ends up in Princess, who is able to resist his control, but keeps him contained and gets access to some of his power.
- Brainwashed and Crazy: What Bubbles and Blossom believe happened to Buttercup. They are wrong.
- Bullying a Dragon: Sure, picking on the mentally scarred girl who can bench-press a mountain just because she's disfigured is such a great idea, Mitch.
- The teacher from the sequel had it coming too, trying to force Cat over and over to repeat the world "ugly" in sign language.
- Buxom Is Better: Buttercup jokingly calls Princess' big breasts one of her greatest assets at one point.
- Contrasting Sequel Main Character: The sequel focuses on Cat, who seems to be on the same path as Buttercup. But where Buttercup was consumed by her anger and ready to give up her old ways for evil, Cat is more confused and the feelings that overtook Buttercup, while still there, are not that strong in her.
- Dark Fic
- Deconstruction Fic: The story takes some small hints of how Buttercup has often been treated unfair in the original cartoon and takes them to their logical extremes.
- The Dreaded: Buttercup notes this is how the Powerpuffs had always seen Him. At the end of first story, when the new Powerpuffs meet Jojo for the first time, they run away. She concludes Blossom had warned them how dangerous she is.
- Evil Costume Switch: Mojo makes a new costume for Butercup. It's actually a suprisingly sweet moment because she really appreciates how much care he put into it.
- Gender-Blender Name: Jojo for Buttercup. With "Joey" as a nickname of sorts.
- Generation Xerox: The new generation of Powerpuffs has clearly taken the traits of the previous one. And Buttercup was the one to add Chemical X to their creation, just like her father Mojo in the creation of the original Powerpuffs. Leading her to believe that one of girls, Cat, will turn out just like her.
- Green-Eyed Monster: It's pretty clear Buttercup's turn to villainy is partially fueled by jealousy of the love her sisters are getting from citizens and the Professor.
- Hypocritical Humor: Mojo, in the sequel, tells Jojo that if he was still alive, he would have her commited to mental asylum — having halucinations of your dead father is a clear sign of insanity. Jojo points out that Mojo himself was insane, and when the halucination protests, she brings up him thinking she was a boy.
- I Have No Son!: After Buttercup kills the entire school and all her friends, Blossom stops thinking of her as a sister.
- Subverted with Bubbles, who still doesn't want to fight her, even after the incident. Double subverted in the finale. Jojo is about to kill Bubbles first, saying she'll spare her knowing the pain of seeing her sister die. Bubbles says she knew the feeling, since Jojo killed Buttercup.
- Irony: Buttercup really resents Him, however in the end, she becomes the only villain the new Powerpuffs fear, just like old ones feared Him.
- She also openly comments how stupid it was for Him to forbid villains from killing the Powerpuffs. Yet in the sequel she sets up the same rule for her group, because she wants one of the new Powerpuffs to turn out just like her.
- Legion of Doom: One of these actually exists, having been founded by Mojo. However, they are horribly ineffective because Him took over and keeps it from actually being a threat. When Mojo and Jojo take over, it becomes much more effective.
- Moral Event Horizon: In-Universe for Blossom — it's the moment when Buttercup kills the entire school that she considers her sister beyond redemption.
- Not as You Know Them: The fic starts when the girls are fifteen, with Buttercup horribly scarred and ostracized.
- Official Couple: Buttercup/Jojo and Princess.
- Scars Are Forever: Buttercup and also Princess. Cat in the sequel.
- Parental Substitute: Buttercup starts treating Mojo as her father, finding in him the acceptance and affection she never felt from the Professor.
- Person of Mass Destruction: The story shows quite well what would happen if somebody as powerful as a Powerpuff Girl turned evil.
- Pyrrhic Victory: In their last fight, Blossom actually beats and almost kills Jojo. However, Bubbles and the Professor got killed, and Townsville has fallen into the hands of villains.
- Replacement Goldfish: Mojo decides to treat Buttercup as his son. When she protests, he says he once had three of them, but they were destroyed. Leads to some funny moments when Buttercup gets romantically involved with Princess and Mojo still acts as if she were a boy (saying he started suspecting his son might be gay and warning her to not get Princess pregnant, among other things). He comes to accept her as his daughter in the end.
- Rival Turned Evil: There are shades of this relationship between Blossom and Buttercup after the latter switches sides.
- Sanity Slippage: In the sequel, Jojo is slowly losing her mind, causing her to have conversations with her long-dead father Mojo. And even those halucinations call her on it.
- Self-Made Orphan: Played with. Buttercup kills the Professor, but at this point it's already hammered down that Mojo is her father as much if not more than him.
- That Man Is Dead: As Buttercup starts thinking of Mojo more like her father, she rejects her old name and uses Jojo Junior, or Joey.
- Too Spicy for Yog-Sothoth: Princess is so stubborn she can resist Him's mind control. The shrapnel embedded in her spine helps.
- The Unfavorite: How Buttercup feels the Professor's been treating her. There are hints she might be wrong. Not that it stops her from killing him.
- Unreliable Narrator: At first you might think some characters are written out of character, but then you realize it's because the story is told from Buttercup's really jaded and frustrated point of view.
- Wrong Genre Savvy: Blossom and Bubbles make some bad calls by assuming some things that would be more typical to their usual adventures — like that Buttercup working with various villains are just different team-ups and not part of a bigger picture.
