Arrow's Next Big Bad Will Be Played By:
YUP! That's Right: Neal McDonough
If you don't recognize him, you'll remember him as Howling Commando Dum Dum Dugan from Captain America: The First Avenger and Agent Carter!
The outlet reports that the show’s producers are describing their take on the character as “a mysterious and sophisticated villain, and an adversary of the late Ra’s al Ghul. Now the leader of his own clandestine group, this cunning foe will prove to be one of the Arrow’s greatest challenges.”
Season 4 is set to premiere on Wednesday, October 7, 2015.
Now just who is Damien Darhk?:
Damien Darhk is the leader of H.I.V.E., and a former member of the League of Assassins. He was the best friend and former rival of Ra's al Ghul, as well as a former "Heir to the Demon". At one point, Damien Darhk and an unnamed man were horsemen of Ra's al Ghul. The former thought himself worthy of taking the mantle, though the latter was the chosen one. Damien was to be killed but managed to escape, taking with him waters of the Lazarus Pit and some loyal followers.
According to Ra's, Damien in the present-day commands a "hive of followers" around the world. He tried to buy the earthquake machine from Milo Armitage then hired Gholem Qadir to release nerve gas in Markovia. Some time later, he also hired Mark Shaw to steal A.R.G.U.S. documents,, but each of his attempts were met with failure.
In 2015, he visited Starling City. He was tracked down by Ra's al Ghul, but both Oliver Queen and he were too late to find him, instead leaving behind his assistant, who was killed by Ra's.
