"P-Please...... Stop! It hurts!"
"Good, it should, cause I just injected something poisonous inside of you. And you should be dead in about one hour or-"
As the body fell unconscious of the liquid nitrogen mixed with spider and snake venom, the black shadow laughed maliciously and the sound of boots clacking against the tiles faded into the halls, leading the doors shut with a loud bang.

       As the nurse stood very still at the main doors, waiting for the cops to come in and she can kill them. And soon enough, the sound of sirens explored the area, making sounds of doors and shouts for "Whoever's in there, come out, we are armed and ready to shoot if any violence occurs."
The nurse with short deep cherry red hair chuckled to herself, the cops had no clue she was an experiment that was now a serial killer. She cleaned herself up by washing out the blood and switching out with a nice nurse's outfit, with a face mask.
She goes out into the dark night, all innocent like and pretended to be out of breathe like she has poisonous gas in her. An experiment should know this, because she had experienced it.
"She's in trouble, give her help!" a cop had ordered.
     The nurse smiling under the mask, still pretended to crouch down and gasp for air. Until at least one cop came to her "aid" and helped her stand. She stuffed a knife down the sleeve and stuck it in the heart of the man on her right and jabbed a sharp syringe in the other man's neck on her left.
The mask fell off and when she looked up, her eyes were filled with pleasure and her smile showed evil.
Shots were being shot at her left and right, with every hit, the pistols would be going through her skin onto the concrete.
"FUCKIN MUTANT!" one cop screamed in fear.
    No one saw the nurse move to the one screaming, and see his jaw being ripped apart, leaving the tongue and bottom row of teeth standing out. The body went limb, and fell onto the floor showing only ripped skin and muscle from the bottom portion.
"Get away from us!" every one screamed.
The nurse had already did something different for each cop, leaving blood flooding the street, covering her clothes and body in blood. The nurse stood unbalanced and looked at the unconscious bodies on the ground.
The nurse laughed hard to the point she was laying in the blood.

       The nurse finally made it to a hospital filled with people that can be dead from injuries and critical wounds.
She enjoyed being there, acting she is the nurse given to the patient, but this time she always gets stopped in her tracks by a doctor with black hair, surgeons coat and outfit, mask with a smile with teeth drawn on, and blood splattered across his body and floor.
"Oh we see each other again. Too late for this one, but there's another one across from here." the doctor told.
"I wanted this one, but that one across is mine and only mine!"
The doctor looked at her, and went back to jar up the organs from the body.

       Every nurse and doctor was gone but those two, leaving every room covered in blood. But every so often, the nurse was slowly becoming more aware of the doctors reasons to why he is at the same hospital she plans to raid.
