(Picture of the character is at the top of the page) Hello, I'm this is "unknown" as they call me. I'm a killing cutie is what the person who made me calls me. I',3 been thought a lot. I have Been trained to killing anything and everything. One day  I was being tested on like always...one of the people who was testing me left for a good 10 minutes...I  tried to get some water across from, I grabbed the wrong glass and drunk some weird stuff. The thing I knew I was asleep. When I woke up I was on the ground! The lab was on fire somehow! I jumped out the window. And noticed my black hair falling out when I while I was falling. I fell on the ground and quickly ran to the woods near by and than I hear a Big Bang! The lab was completely gone. Dead people everywhere. I ran to the lab and saw everyone who tested me dead. They're faces were fucked up. I didn't know what to do. I was starting to feel scared...one of the emotions I know to well. I felt somewhat happy to...at the time. I quickly ran to the woods hopping I would find somewhere to go. I ran for hours...and hours. It was night time at the time I got to a road. I started walking down the road. I was going over what happened in my head over and over again. I was slowly losing my mind. I had someone's else's blood all over me, My black hair was falling out. My  eyes started hurting..as if something was trying to get out of my head. I walked for days and days. 7 weeks later...all my hair was gone..my eyes were completely black, my feet were black with blood."I haven't slept in days...I'm going to-" I said before falling down and passing out.
