Another DC Comics character is coming to Starling City when The CW's "Arrow" premiers this fall.

According to The Hollywood Reporter, actor David Cubitt has been cast in Season 3 as Mark Shaw. The "Medium" star will be introduced during the third episode of the new season as an A.R.G.U.S operative in Corto Maltese who crosses paths with Diggle. He also has ties to the Suicide Squad, which was featured last season on "Arrow." Eventually, Mark will take on the mantle of Manhunter.

In the DC comics, Manhunter is a name taken on by multiple characters who are part of a sect of ancient crime fighters with ties to Green Lantern. Starling City district attorney and prosecutor Kate Spencer was also a Manhunter before she was killed last season.

The English-born Canadian actor joins a growing list of casting additions to "Arrow's" upcoming season, including actor J.R. Ramirez has been cast as Ted "Wildcat" Grant, according to Deadline.

Ted is a former boxer who will operate a gym for underprivileged children in Starling City. In the DC Comics, however, Ted is a member of the Justice Society of America who specializes in mentoring and training crime fighters like the Black Canary.

In addition to Wildcat, Ra's al Ghul will also pop up as Oliver Queen's ongoing nemesis of the season.

According to Hypable, the official synopsis for "Arrow" Season 3 reads:

In the aftermath of this victory, Season 3 opens with Arrow now a hero to the citizens of Starling. Crime is down, people feel safer, and Captain Lance even calls off the Anti-Vigilante Task Force. Basking in his success, Oliver believes he can finally have a private life and asks Felicity out on a date. But the second Oliver takes his eye off the ball, a deadly villain reappears in Starling, forcing Oliver to realize that he can never be Oliver Queen - not as long as the city needs The Arrow.

"Arrow" premieres on Wednesday, Oct. 8 at 8 p.m. ET/PT on The CW.
