Once again, Supergirl landed at Comic-Con with another superpowered panel filled with surprises and reveals about the eagerly awaited upcoming season. Perhaps most striking for fans is that the character of Kara Zor-El aka Supergirl (played by Melissa Benoist) will be sporting a new Kryptonian supersuit - the first revamp since her co-worker, friend, and confidante Winn Schott designed her iconic red and blue gear in season one. And two new characters will also be on the scene in National City this season.
