(I know I'm late but I thought this would be fun, so enjoy. Also there may be some things that will appear in the future of this story)

Lucy is seen drawing in her notebook and listening to music but her phone starts ringing. Lucy stops what she was doing and answers.

Lucy: "helloooo"

Ghostface(phone): "is this Lucille"

Lucy: "yeah, how did get this number and who are you"

Ghostface(phone): "I'm your biggest fan, now tell me what do you like to watch, a favorite movie-"

Lucy: "The Texas chainsaw massacre 2"

Ghostface(phone): "I really? Wha-"

Lucy: "Choptop"

Ghostface(phone): "anyway don't you have your favorite dead family"

Lucy gets pissed at this statement

Lucy: "I'LL KILL YOU!"

Ghostface(phone): "on the contrary"

Ghostface: "I'll be the one to kill you"
(I couldn't think of anything better)

Ghostface jumps at Lucy in attempt to kill her but Lucy dodges the attack with ease.

Lucy: "you're not the first psycho I killed"

Ghostface: "Lucille, it's an honor"

Lucy starts shooting cinder shots at Ghostface, who dodges some of them before making a beeline for Lucy and managed to slash Lucy more than once. Lucy shoots a smoke blast sending Ghostface through a pair of double doors into a dark warehouse.

Lucy: "no more hiding in the dark"

Lucy absorbs neon from some glow sticks on hand. Suddenly Lucy is shot at from the darkness, but Lucy tanks the shots. Lucy sees where Ghostface is va his soul.

Lucy: "I found you!"

Lucy dashes to Ghostface and attacks, but Ghostface suddenly disappears before her eyes. Ghostface cuts a deep wound into her before disappearing once again. Lucy wounds heal before getting slashed again. Ghostface tries for a third time but lucy stops the attack and sends a fury of neon punches before one final punch that sends Ghostface flying. Ghostface crashes into some barrels.

Lucy: "say hello to hell"
Lucy throws a grenade at Ghostface but he throws it back with some of his own.
Lucy: "ah gre-"

Lucy is sent through the wall of warehouse and into the alleyway. Lucy gets up without any harm. Lucy is knocked off her feet from an invisible Ghostface. She jumps up but before she can do anything, Ghostface stabs Lucy.

Ghostface:

[There should be a GIF or video here. Update the app now to see it.]

Ghostface starts to cut and stab Lucy in quick succession before kicking her.

Ghostface: "ah Lucille, I had kill you first"

Lucy: "agh, what?!"

Ghostface: "there's been too many intrusion of characters who don't belong but I will change that."
Ghostface pulls out a glowing ticket
Ghostface: "I will kill all those characters for ruining such good shows and movies"
Ghostface is shown killing multiple people with one being Charle from 101 Dalmatian street the soldier boy. another victim being Silas from helluva boss: Silas. The final victim being Julie from the rookie. As Ghostface is talking, Lucy's wounds heal and she does her own disappearing act
Ghostface: "don't you see Lucille, I can save franchisees from people ruining it with their creations."

Ghostface: "starting with you"

Ghostface turns to see Lucy gone

Ghostface: "wh-"

Ghostface is impaled by a neon katana

Lucy: "2 things, one my name is Lucy and two do your research"

Lucy sends the rest of blade through Ghostface almost spitting the killer in two.

Lucy: "what's this? Lucy spots the ticket he won't be needing this anymore"

Lucy grabs the ticket and sends Ghostface's soul to hell

Lucy: "hopefully Alex and Jonas can figure out how this thing works"

(Silas belongs to @LucianXY)
(Charle belongs to @deamion001)
And (Julie belongs to @fan man 50)
