THE FLASH

While the new trailer for The Flash debuts the DCU's brand-new Supergirl, her origins may be taking inspiration from another major comic story beyond Flashpoint. Played by Sasha Calle, this new version of Superman's cousin will come onto the scene during a collision of worlds thanks to the unintentional efforts of Barry Allen's Flash. However, some interesting teases suggest Supergirl's debut will resemble one of DC's greatest Elseworlds stories from the comics.
