IMPULSE

My name's Makayla Allen, and I am the fastest girl alive. When I was just a baby and my brother was a child, we saw our mother killed by something impossible, but my father went to prison for her murder. Then, an accident made us the impossible. To the outside world my brother is an ordinary forensic scientist and I'm a regular teenage prodigy, but secretly my brother and I use our speed to fight crime and find others like us. And one day, I'll find who killed my mother and get justice for my father.

I am Impulse.
