When I was a child, my planet, Krypton, was dying. I was sent to Earth to protect my cousin. But my pod got knocked off-course, and by the time I got here, my cousin had already grown up and become… Superman. And so, I hid my powers, until recently when an accident forced me to reveal myself to the world. To most people, I am an assistant at CatCo Worldwide Media. But in secret, I work with my adoptive sister for the D.E.O. to protect my city from alien life and anyone else that means to cause it harm. I am Supergirl.
