Fan Casting Supergirl (Season 5)

What if Supergirl was actually good? This is pretty much a redux of the CBS/CW show Supergirl with my own casting, my own ideas, and what I view would be a much better show. In the final season of the show, Supergirl goes back to fighting easier and smaller threats. However, a new mysterious stranger named Morgan Edge is trying to defeat Supergirl for vengeance against his friend, Maxwell Lord, but it may not be as it seems. He's also working with not only the evil organization Cadmus, but Lena Luthor as well.
