Supergirl is front-and-center in the new trailer for The Flash, which will have its first official screenings at CinemaCon. The film, loosely based on the 2011 comic story Flashpoint, takes place in an alt-timeline created when Barry Allen tries to rescue his parents from death and imprisonment by going back in time - and where Zod, the villain of Man of Steel, reigns over Earth with an iron fist.
To fight Zod, Barry (or Barrys, as there are two versions of him in the film) recruit a Kryptionian of their own to their cause, but not Kal-El. Instead of Superman, they recruit Supergirl (Sasha Calle), reportedly a version of Kal-El's cousin Kara Zor-El.
