ARROW SEASON 4
The Comic-Con panel also revealed that two more DC Comics characters were on the way to Starling City; Mister Terrific, who will appear as a friend and coworker for Felicity. Greg Berlanti pointed out that their version of Mr. Terrific would be gay. This is in response to fans wanting more LGBT characters on the show. Diggle (David Ramsey) will also be getting a costume in season four — including a mask or helmet.
