"Subject 864! Come down to the lab! This is your last warning!"
The young faunus sat in the corner of her cell whimpering, refusing to be tested on, not again. When the door opened, she tried to run out, past the guards, but they grabbed hold of her and started hauling her to the testing chamber, with the faunus kicking and screaming all the way.
"Tch, damn animal. I don't see why they even exist." Guard 1 said to Guard 2. Upon reaching the chamber, the guards threw the faunus onto a table and strapped her in.
"About time you got here, you two took way too long."
"Sorry professor." Both guards say simultaneously.
"Forget it, I think we're gonna have a breakthrough here, I'm getting impatient." The two guards exited the room. The professor started inserting needles into the faunus and draining its contents into the faunus.
"AAAAAGGGGHHHHHH!" She started screaming, feeling as if her skin was burning, everything was burning, melting, and started begging for the pain to stop. Shadows started contorting, reaching out to the faunus, engulfing her, with a mask appearing on her face. Eventually, a grimm that had a human like structure, with cat ears on the top of its head and glowing red eyes, was on the table. The grimm roared.
"HAHAHA, it worked! I told you it would!" The professor was talking to nobody. Just talking to air like a madman. The grimm currently on the table broke its bindings and leaped at the professor, tearing him to pieces. The guards came in, hearing the professor scream, seeing the grimm attacking the professor. Guard 2 ran out to sound the alarm while the other guard stayed behind, pulled out his gun and started shooting the beast.
"Die, you fucking monster! Die already!" The grimm pounced on the guard, ignoring the bullets that hit it. At that moment, the alarms went off, red light flooded the room and halls.
"Alert, alert! Subject 864 is attacking! We need people at lab 3! Now!" As the rest of the guards ran to the lab to kill "subject 864" the grimm burst out of the room, startling the group. "Kill it!"
~~~~~~~~~~Some time later~~~~~~~~~~
The faunus girl had changed back to normal later, to see dead bodies around her, blood everywhere. She curled up into a ball and started crying, trying to remember what happened. She heard a crunch and turned around. There stood a boy, around the age of 10.
"Hi there, I'm Adam Taurus. What's your name?"
"Blake. Blake Belladonna."
