    My name is Kara Zor-El. I'm from Krypton. I'm a refugee on this planet. 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. I hid who I really was until one day when an accident forced me to reveal myself to the world. To most people, I'm a reporter at CatCo Worldwide Media. But in secret I work with my adopted sister and my friends to protect my city from anyone that means to cause it harm. I am Supergirl.

Now, Kara balances her work as a reporter for CatCo Worldwide Media with her work as Supergirl, keeping National City and the Earth safe from sinister threats. She's joined in this pursuit of justice by her sister, Alex, her mentor, Martian Manhunter and her friends Brainiac-5, Dreamer and Lena Luthor.
