From Jinchuriki to Speedster

My name is Nathaniel Allen. When I was a child, I saw my mother and brother killed by something impossible. My father went to prison for her murder. To the world, I'm an ordinary forensic scientist, but secretly I use my super speed to fight crime and find others like me. And one day, I'll find who killed my mother and brother. I am the Flash.
