Kara Danvers, also known as Kara Zor-El on her homeworld, is a fictional character in the Arrowverse franchise, mainly the television series Supergirl. Adapted for television by Greg Berlanti, Ali Adler and Andrew Kreisberg, the character is based on the DC Comics character Kara Zor-El (Supergirl), created by Otto Binder and Al Plastino. Kara is introduced in the pilot episode as the adopted younger sister of Alex Danvers. Kara Danvers is portrayed by Melissa Benoist as an adult, and Malina Weissman and Izabela Vidovic as a child.[1][2] After her planet, Krypton, was destroyed, Kara and her cousin Superman came to Earth. There she became the adopted sister of Alex Danvers and, later, after deciding to use her powers (equal to Superman's) to help others under the persona of Supergirl, she discovers that her sister is part of the Department of Extranormal Operations (DEO), a massive underground anti-alien organization secretly under the control of the Martian Manhunter. She is a friend and frequent ally of the superhero speedster the Flash and vigilante archer Green Arrow.
