Farscape star Ben Browder is to appear on Arrow. Browder will play DC Comics character Ted Gaynor - first introduced in 1984's Blackhawk #266. In the original comics, Gaynor was a top-class marine who went rogue and fought both Batman and Blackhawk. Arrow will introduce the character as an old war buddy of Diggle (David Ramsey) who causes tension between the bodyguard and Oliver (Stephen Amell), according to IGN. Browder is best known for his roles on Farscape and Stargate SG-1. The 49-year-old actor also recently played a guest role on Doctor Who. He will make his Arrow debut in the show's 11th episode 'Trust But Verify' - currently slated to air in early 2013.
