'Supergirl' Already Has Her Own Rogues Gallery

Part of a shadowy alien cabal intent on taking over the Earth, the Commander is a character created for the show and has no comic counterpart. While Kara has been growing up with the Danvers family, the Commander has been organizing the villains of Fort Rozz and preparing for the arrival of General Astra. Astra bears a striking resemblance to Kara’s biological mother, Alura (both roles are played by actress Laura Benanti), because she’s her sister. Unfortunately, blood isn’t thicker than water on Krypton because Astra makes killing Kara her first order of business.
