Area 51 SCP (insane alastor x doctor reader)

long time no see

You sat at a small table early in the morning. It had cooled off and you where drinking some hazelnut coffee, while listening to the radio. It was mostly country and jazz, you even heard My Chemical Romance, black parade. You had to admit, that song was catchie.
You peel your eyes away from the window to see a tall red Deer standing in the door way, which made you jump. But you already recognized the laught, and the eyes.
" Hello my dear! Look here, I forgot that I could do this! " Alastor says with a chuckle. You smile and tilt your head. " You can turn yourself more adorable? I never knew! " You say giggling.
He leaps over on top of the table nearly spilling your coffee. " I am the all mighty radio demon! " He says with pride.
You just smile a laugh. He leans his head down and gives you a peck on the cheek. You rub his soft fur, and he lays down on the table for you, resting his head on your chest and enjoying the pets your giving him. You were enjoying it as well, that is until you hear a loud crash, and alastor falling off the table, stiff. Like a deer in head lights.
You run into the other room and you see angel, husk, and mimzy blocking the door using the couch, some chairs and tables.
" What's going on?! " You ask. Alastor goes back to his normal form and peers out the window. A large snarl spreads across his face.
" He's back.. " He mumbles.
You are hit with worry. There's only a few people you knew who hated you and alastor like some of the nurses and...
" Oh my god. I-is it the?.. " You could not even finish your sentence, but alastor alright knew what you were thinking.
" The doctor.. "
Just then, the door and everything blocking it flew off the wall and slammed to the back of the room, along with poor little niffty. You sprint to the wreckage and throw off the chair, seeing little nifftys hand sticking out, and you quickly move more of the things to get her out along with husk lending a hand ( or paw).
Turning your head, you are met with daggers for eyes.
" Well well well... Look what the cat dragged in. " He hisses, shooting you a glare. " You little shit.... YOU TOOK MY LIFE AWAY... "
Alastor quickly goes in front of you, in a defence stance.
" You stay away from her.. " He snarls. You hold niffty close, patting on her cheek to wake her up.
" Niffty? Niffty can you hear me?! NIFFTY?!?! " You yell, panicking over not getting a response. You place two fingers, on her neck and check her pulse.
.........
Alastor turns his head and looks, ears going down. " Niffty?... " He asks, his voice shaky. You set her head down on the floor, and close her eye. 
You don't know what was going on, but your chest burned, like what the doctor did lit a flame in your chest that took you back... To the church...
You open your (e/c) eyes, burning with fire, literally. Your (h/l) glows as bright as the sun and you hold in your hands balls of fire.
The doctor looks at you with a bit a fear as he stands up straight. " You w-wanna go girl?!. " He hells pulling out a hand gun and cocking it. But you just get angrier when he points it at alastor. You sprit towards alastor and as you get to him, the gun shot rings through the lobby, making alastor, cover his ears since he was sensitive to loud noises.
When he opens his eyes and looks at you, but sees you with your fist out.
You unroll your fingers and the bullet falls out, crushed.
" you killed her.... You killed niffty... Tortured my friends... Tortured the one I love..... " You say softly, voice echoing in the room.
" I did what I needed to do! I banished them to hell by killing them! " He yells.
" If this is your way of fixing things..... " You say as you form a scythe of fire and char. " THEN YOUR JUST AS BAD AS ME.. "
you lunge and him and cut him in the chest, knocking him to the floor. He yells in pain and tries to fire at you again. But yet again failed to hit the target.
You swiftly grab him buy the neck and slam him into a wall. You slowly push the scythe to his face, watching as his skin melts and bubbles of the surface, him crying out in pain.
" What was it that holy one would call people?... Children?... " You ask. The doctor just looks at you and spits out a bit of blood.
" Well... " You start, forming shards of what look like hot glass, and pressing them on his palms, and into the wall.
A crucifixion....
" I will leave you at the mercy of your children.. " You turn your head towards the outraged group behind you and nodded. They all smiled menacingly as they slowing caved in around the doctor, horrified and in pain, and soon screaming like his was the only one in the world.
Everything seemed to go still when two claps broke the silents. Everyone turned around to alastor, standing there.
" I think it is my turn, dear friends... " He says darkly. Everyone knew what he was going to do, so they stepped back a far distance to avoid the " Splash zone. "
Alastor walked up slowly to him and stopped in front of his face." You have no idea how long I've wanted to do this..." With one move, alastors claws were around his throat, and draining what blood was left in his body. His large smile soon became a snarl and he rips the spine out of the doctors neck and slaps in across his body like a wip, laughing hysterically.
You walk closer to him and see tears rolling down his cheeks.
You are hand cools down and you take his bloody hand in yours and look into his eyes.
" It's ok my love.... He's gone now... " You say softly putting a hand on his cheek. He nuzzled into your hand and pulls you close.
" Yes... Over... " He says.
" And if it's not... I will do what ever it takes to keep you safe... Even if it means I die...
