I was the 1415th genetically modified creation scientists at the Wright Laboratory Institutes sufficiently made. Each embryo used before me failed and died, except for three. Leaving only four of us out of the 1415 experiments. 

I was the most successful one being the only one with unmatched skills no human could ever do; the perfect lab experiment with refined hearing, incredible flexibility, sharp sense of sight and taste, and immunity to most diseases, as well as incredible learning ability and skill. I was only made for one purpose: to kill. 

My other colleagues, or should I say genetically modified humans, were very... different but also the closest thing to a family I have. The first one who was successfully born who didn't die in the stomach or as embryos was a girl, just like me. She had mental retardedness and the scientists decided she was useless and worthless to them so they threw her away. The second was a boy who got sick very easily, too easily and died off on his own over the flu, his heart wasn't strong enough for it. The third was also a boy who grew up stronger than any human ever, breaking every Olympic record, he was three years older than I was, more aggressive and tempered.

Then there was me smart, mischievous, and quite ready for anything. The scientists decided we made a good pair and so far kept us that way. For as long as I can remember we've been training to become assassins. Fighting against our nemesis the Crows. We were the top gangs in the city the most feared in our own country even who can't even touch us. 

  "Contestants be ready in three... two... ." A robotic voice came from above me. I started reviewing my plans of how I was going to beat him... or them, and before I knew it the red light became green and the screens and walls opened from all around me. I leaped into the air, grabbing a metal pole above me and pulling myself to sit on it. I wiped my white hair away from my brown eyes and could already fell a thin layer of sweat from the suspense. 

I looked down, the surroundings were plain, lifeless, motionless. The immense amount of silence was starting to kill me. The metallic silver walls seemed to form a maze one I was intent on memorizing. Then I saw it, the group of weapons all sitting like treasures waiting to be discovered. As soon as I leaped down I saw him guarding the weapons like a dragon guards gold. The boy who went by Rex, the only genetically modified human besides me. The scientists named me Katia because they thought it sounded smart just like myself. 

Although Rex was smart too, he knew that he could beat me without weapons because of his strength and the only way I would beat him was with weapons, which was why he was guarding them. 

Fine, I told myself, if I can't get those weapons I'll just make one myself. I took off my black belt and held the silver lining in the palm of my hand shaping it like a very unsharp knife. I walked towards the weapons and hide behind a cold wall for cover. I looked towards the general direction of the area to find he wasn't there. Maybe he went to look for me, I thought before I felt something grip tightly around my neck and something sharp in my back, I immediately knew the feeling, Rex's cold hand and a silver knife at my back.
