Arrow unveils new villain Prometheus in season 5 photos

Oliver Queen is going to have his hands full in season 5 of Arrow.

Not only is he the new mayor of Star City, but Oliver (Stephen Amell) will be facing off against a mysterious new villain Prometheus, while also building up a new Team Arrow — Diggle’s (David Ramsey) back in the military and Thea (Willa Holland) is apparently adamant about hanging up her hood as Speedy. Though she does suit up in the new photos from season 5 below, which also feature a look at Oliver’s past in joining the Russian Bratva, as well as a glimpse at the new baddie.

Not yet pictured: the ever-expanding list of new and returning characters in season 5, including Dolph Lundgren as Russian baddie Kovar; Chad L. Coleman as a new villain; Madison McLaughlin, who will reprise her role as Evelyn Sharp; Joe DiNicol as Ragman; Tyler Ritter as new cop Detective Malone; Rick Gonzalez, who will play Wild Dog; Carly Pope as a new Star City reporter; and Josh Segarra, who will take up the mantle of the Vigilante.

Arrow returns Wednesday, Oct. 5 at 8 p.m. ET on The CW.
