We don’t yet know who’s playing him, but the mystery villain Prometheus looms large in the first set of photos from Arrow Season 5.

There’s also Oliver in a suit that is neither green nor leather, a Speedy sighting and the return of frenemy Anatoly Knyazev (played by David Nykl), who is accompanied by seemingly half the population of Luchegorsk.

An official description of the Season 5 opener follows:

After Laurel’s (Katie Cassidy) death and the departures of both Diggle (David Ramsey) and Thea (Willa Holland) from Team Arrow, Oliver (Stephen Amell) takes to the streets solo to protect Star City’s citizens as the Green Arrow. With Felicity (Emily Bett Rickards) guiding him from the bunker, Oliver is forced to deal with a city that has become overrun with both criminals and a slew of new (and painfully inexperienced) vigilantes. Watching Oliver try to balance his jobs as both the mayor and also the protector of Star City, Felicity suggests he form a new team, but Oliver resists. However, when a deadly new criminal, Tobias Church (guest star Chad L. Coleman), enters the picture, Oliver realizes the best thing for the city might be a new team of superheroes. Meanwhile, the flashbacks take us to Russia where Oliver faces off against the Bratva.

Arrow Season 5 will feature a variety of fresh faces, including Rocky IV opponent Dolph Lundgren (as a Big Bad in the Russia flashbacks), Popular alum Carly Pope (as a Coast City reporter), Chicago P.D.’s Josh Segarra (in the series-regular role of D.A. Adrian Chase aka Vigilante), Reaper‘s Rick Gonzalez (as the DC Comics character Wild Dog), The McCarthys‘ Tyler Ritter (as SCPD Detective Malone), Blindspot’s Joe Dinicol (recurring as Rory Regan aka the vigilante Ragman) and former WWE grappler Cody Rhodes in a guest role TBA.

Katie Cassidy — who is now a series regular across Arrow, The Flash and Legends of Tomorrow — will return in the season opener to spill what Laurel told Oliver before her death.

Arrow returns Wednesday, Oct. 5 at 8/7c on The CW, where it now leads into the freshman drama Frequency.
