In addition to Damien Darhk (Neal McDonough), “there’s another big [DC character] coming,” Geoff Johns teased. “There’s a lot of characters coming up that people won’t really guess” from the DC Universe. Two that were unveiled during the panel:
Anarky, who may be familiar to Batman fans, and
Mister Terrific, who works with Felicity and is a good friend of hers, Berlanti previewed. He also happens to be the show’s first gay character.
