David Cubitt is on his way to Starling City.
The former Medium star will appear on Arrow Season 3 as Mark Shaw, an A.R.G.U.S. operative who turns into the DC Comic character Manhunter.
According to The Hollywood Reporter, Shaw will cross paths with Diggle and have a connection to The Suicide Squad.
As teased at Comic-Con last month, DC villain Ra's al Ghul will be the Big Bad this fall on the hit CW drama, with executive producer Marc Guggenheim teasing that this version of the villain will differ from the one seen in Christopher Nolan's Batman films.
"We really wanted our Ra's to be very different - at least our own Arrow-ified version," Guggenheim said.
Other big additions to Arrow Season 3 (premiering October 8) include:
- Atom/Ray Palmer (Brandon Routh).
- Wildcat/Ted Grant (J.R. Ramirez).
- Felicity's mother (Charlotte Ross).
- Maseo (Karl Yune).
- Katana (Devon Aoki).
- Count Vertigo (Peter Stormare).
NOTE: you can watch Arrow online at any time via TV Fanatic in order to catch up.
