Back in March, Mike Colter, who plays the title character in the upcoming Marvel/Netflix TV series Luke Cage, revealed that the series will premiere on September 30. Production has been under way since February, and the show is still shooting in New York, although we don't know when filming may wrap. Today we have new photos from the set, which give us our first look at one of the show's previously-unannounced villains, Willis Stryker, a.k.a. Diamondback.

The photos have surfaced throughout Twitter, where it has been confirmed that Diamondback is being played by actor Erik LaRay Harvey. The photos showcase a street fight between Diamondback and the Power Man himself, Luke Cage, but we don't have too many details about how this character is introduced, or if the show will stick close to this character's comic book roots. It isn't known how many episodes of the first season Diamondback is slated to appear in.

Willis Stryker/Diamondback made his debut in the 1972 comic Hero for Hire #1. Stryker is a longtime childhood friend of Luke's, until Stryker frames him for a drug charge when they're young, which results in Luke being sent to prison. It's possible that these powerful characters could be fighting over Diamondback's betrayal of Luke, but we'll have to wait until the show premieres this September on Netflix. Regardless, Erik LaRay Harvey is joining a talented cast that keeps growing.

After a sabotaged experiment leaves him with super strength and unbreakable skin, Luke Cage (Mike Colter) becomes a fugitive trying to rebuild his life in modern day Harlem, New York City. But he is soon pulled out of the shadows and must fight a battle for the heart of his city--forcing him to confront a past he had tried to bury. The supporting cast also includes Rosario Dawson, reprising her role as Claire Temple, a.k.a. Night Nurse, Mahershala Ali as Cottonmouth, Theo Rossi as Sonny, Alfre Woodard as Black Mariah, Simone Missick as Misty Knight and Sonia Braga as Claire Temple's mother.

After Luke Cage debuts this fall, the next Marvel Netflix show to debut will be Iron Fist, which has recently cast Finn Jones as Danny Rand. While we still don't know when that series will arrive, it will lead into The Defenders, which will unite Daredevil, Jessica Jones, Luke Cage and Iron Fist. Defenders will be followed by The Punisher standalone series, which also doesn't have a premiere date at this time. Take a look at the latest Luke Cage set photos, and stay tuned for more details as we get closer to the September 30 premiere date.
