Gear the human bio weapon

ok this is my other flash story, this one is about me. As it turns out I was developed to be the 1st human bio weapon, but after escaping the lab I was made in, I had a huge brain wipe, wiping out all infomation about the lab. In this time were I have been trying to fit in, back at the lab they have been creating another Version of me, This one they called Yin. He was the perfect weapon, untill he realised that he wasn't free and that humans were the only thing holding him back. Like James 3 years before Yin tries to kill every human in the world, I am called apon to stop him.
