The first season had Astra, the second Lillian Luthor and Queen Rhea. Now, “Pure Genius,” “House” and “The Unborn” actress Odette Annable has been cast as the main villain of the third season of The CW’s “Supergirl”.
Annable will play Reign, a character first teased in the final moments of the Season 2 finale. In the New 52 comics, Reign is a female ‘worldkiller’ – a bioengineered blood-thirsty, super-powerful being outlawed by the Kryptonian Science Council.
The series intends to partly interpret the infamous World Killer storyline from the pages of the DC Comics for the new season. “Supergirl” will return in the Fall.
