TV Line reports Katie McGrath (Dracula, Merlin, Jurassic World) will play the sister to Lex Luthor (who hasn't been cast for Supergirl), with the character described as:
“Beautiful, powerful, and enigmatic, Lena arrives in National City on the heels of brother Lex’s incarceration hoping for a fresh start. Lena has taken over as CEO of her family’s billion-dollar-tech company, Luthor Corp, which has been tarnished by Lex’s evil infamy. Her goal? To re-brand the empire as a force for good. Lena wants to be seen as her own person, separate from her brother. Kara is drawn into Lena’s sphere and must determine if she is friend or foe.”
Supergirl Season 2 premiers this October on The CW also starring Melissa Benoist and Tyler Hoechlin as Superman.
