New Villains Are Coming
With new heroes coming, you had to know there would be some big bads to match. The season three finale sets up Damien Darhk as season four's potential supervillain. Since then, Neal McDonough was cast, and costar Paul Blackthorne shared a picture of him in character. He'll be in good (or should I say, bad) company, with Baron Blitzkrieg (Jimmy Akingbola), Anarky (Alexander Calvert), and Vandal Savage (Casper Crump), a character who will eventually move to DC's Legends of Tomorrow in 2016.
