You Can Run Away With Me Anytime You Want...

You Can Run Away With Me Anytime You Want... is a Danger Days: The True Lives of the Fabulous Killjoys (My Chemical Romance concept album) Fanfiction by Ally Kat Tomlinson. At time of publication, it's been published on both Quotev and Archive of Our Own
Timeline and notes:It takes place in the summer of 2019, a few months before the events of the Danger Days Music Videos—Na Na Na (Na Na Na Na Na Na Na Na) and SING. Unlike many popular Killjoys verse fics, it sticks to Canon pretty much to a fault. (As in Party Poison is referred to with he/him pronouns among other things).
The heroine of The True Lives Of The Fabulous Killjoys: California Comic Book, often called The Girl, is referred to as Missile Kid and her name is explained to be derived from the fictional Punk band, Mad Gear And The Missile Kid. 
It's also written in Third Party POV.
 Plot synopsis:The metaphorical curtain opens on the Prologue, where The Fabulous Four along with Missile Kid are driving in Zone 5 and happen upon a Cemetery Drive (Killjoy Slang for an ambush site). They stop and check it out to see it was an all-out slaughter except for one girl, known as Diamond Demolition.
Her injuries are serious, but treatable and they take her back to their hideout in Zone 6.
In Chapter Three, she's conscious and stable again that night. There's a banterous scene where her, Party Poison, Kobra Kid and Fun Ghoul play Scrabble. Surprising no one, she won.
In Chapters Five and Six, it's decided that she'll be bunked with Poison, sending them both into slight awkwardness (mostly on her end) and Kobra and Ghoul to tease them (Miss Tomlinson notably utilizes the There Was Only One Bed Trope).
In Chapter Seven, she spirals, telling Poison he's trusting and that she could be a psychopath, and possibly the best couple paragraphs of the whole book plays out here:
Characters:
Diamond Demolition:
Diamond is quiet and introspective, notices EVERYTHING and has the memory of an elephant. She belonged to a gang of Killjoys known as The Joyriders, until their deaths at the beginning of the book. Her hair is dyed cobalt blue but was naturally blonde and she has lavender eyes. 
She's been an orphan since she was seven or eight and raised herself, hence her quietness and maturity. She's a biker and has an orange Harley-Davidson. After Poison found her at the beginning of the story, he didn't know her name for quite a while so he took to calling her "dollface", and learning her name hasn't stopped him.
Party Poison:
The flirtatious, sarcastic leader of The Fabulous Four. He's fairly sensitive underneath, but only like three people know that. Fairly serious, but has a boyish charisma that is irresistible and is known to be able to talk his way out of tight spots. He's also a fairly good (if occasionally reckless) driver.
He's extremely protective, growing up watching out for his little brother, Kobra Kid. That has now more or less transfered to both Missile Kid and Diamond in big ways, while he's still very protective over Kobra, even though he knows he can handle himself for the most part.
A comic book nerd, as is Kobra, but to a lesser degree.
Fun Ghoul:
Poison's second-in-command and who he'd consider his best friend, if asked. He'd probably be declared insane by most doctors, and likely declared unfit to exist by Better Living Industries, both because he's a Killjoy and he's literally crazy. His joking nature comes in handy in tense moments, but his immaturity gets on peoples' nerves sometimes. 
Kobra Kid:
Party Poison's little brother, basically a more reserved version of Ghoul. He's the closest to Missile Kid as far as their personalities and mental ages. Some seem to think he might be autistic, but this is debated and no one really knows for sure. He's the most physically affectionate of the gang, so he's the one that Missile Kid is always falling asleep on, pretty much never fail.
A kinda bad shot, he likes hand to hand combat, specifically karate, which is probably because he watched a lot of bootlegged Bruce Lee movies as a kid. 
Almost died a while before the book with Jet-Star after a clap with an Exterminator out on Route Guano (the events detailed in Dr. Death Defying's Jet-Star And The Kobra Kid/Traffic Report but they both managed to pull through.
Jet-Star:
Inarguably the most mature of the four, was, like Diamond, orphaned at a young age. He's blunt, to the point it's tone-deaf and borderline rude, meaning the much more diplomatic Poison has been caught in the crossfire of covering for him more than once.
Despite his careful nature, he's accident and injury prone, earning the title of "Biggest Crash King In Zone 6". He almost died after the clap on Route Guano and actually came closer to death than Kobra did.
Missile Kid:
Born in or around 2013, during The Analog Wars, to a warrior mother who once led the gang known now as The Fabulous Four (known then as The Fabulous Five) and an unknown father who is often thought to have been a rouge exterminator, but no one knows for sure.
Her mother was taken by BLI and never heard from again (she's assumed dusted, but again, no one knows for sure) when Missile Kid was about a year old. The boys have raised her since then, trying to give her the best possible childhood and overall life. They behold her as a bit of a "chosen one who will save us", a savior of the broken and the beaten, if you will. Perhaps she is, or perhaps it's under the "desperate people find faith" mentality where in a wasteland, you need something to hold onto, some sort of hope, just like the droids believe DESTROYA will free them.
Whatever she is or isn't, she's a child prodigy with electronics. She likes messing around with radios, more often than not fixing them. She's also on-call at Dr. Death Defying's radio shack when anything goes Costa Rica over there with the broadcasting stuff.
She takes a while to get used to people (but didn't we all at her age?) but when she does, she's quite friendly.
