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.
