The cast of Supergirl continues to grow, and the latest addition is Floriana Lima (The Family). She'll be a recurring presence in The CW series moving forward and is set to star as Maggie Sawyer. Created by John Byrne, the character first appeared as a member of the Metropolis Special Crimes Unit in 1987 dealing with metahuman threats. She would later be revealed to be a lesbian in the pages of Superman and ended up embarking on a romantic relationship with fan-favourite superhero, Batwoman.
This version of the character is described as being, "a detective for the National City Police Department who takes a special interest in the cases involving aliens." That may be a sign that we'll be moving away from the DEO, no bad thing now that Alex Danvers and Martian Manhunter are no longer part of the organisation as they set out to learn the truth behind the the fate of Alex's father.
Season two of Supergirl is shaping up to be great so far with the addition of characters like this, Superman, and a very different take on Snapper Carr. Original Wonder Woman star Lynda Carter has been cast as the President of the United States. This doesn't mark Maggie's first appearance in live-action as she was played by Jill Teed in Smallville. There's been no sign of her in the DC Films Universe.
