After being teased in the Season 2 finale of Supergirl, the big bad for season 3 has officially been identified as the New 52 Supergirl villain known as Reign.
The character of Reign, created by Michael Green and Mahmud Asrar, was taken by Kryptonian scientists when she was just an infant and experimented on. They gave her abilities which turned her into the tragic world-killing villain.
Brothers and Sisters alum Odette Annable has been cast as the evil villain and will be joining the show as a series regular.
Showrunner and Executive Producer of the series, Andrew Kreisberg had this to say about the casting choice:
“Greg [Berlanti] and I have wanted to work with Odette for years. We are beyond excited to have her join our cast in the scary, powerful and heartbreaking role of Reign.”
