David Harewood has been cast as Hank Hershaw, who DC Comics fans will know as Cyborg Superman. He won’t start off that way though. At first, he’ll be “A onetime CIA agent, who now runs the Department of Extra-Normal Operations (DEO), which tracks extraterrestrial threats on the planet Earth.”
Then, Chyler Leigh has been cast as Kara’s foster sis Alex Danvers. Who will fully know who Kara “really is”, and is “fascinated by Kara’s powers from a young age, Alex developed a lifelong obsession with science which inspired her to become a doctor.”
Supergirl is set to arrive this fall on CBS.
