Netflix just released a bunch of new images from its upcoming Marvel series "Jessica Jones," giving fans their first look at the titular character and other key members of the series's supporting cast.

Krysten Ritter stars as the titular character, a former superhero who's renounced her powers after a tragic event. Now, she's working as a detective in New York City, though she's still attracting the attention of others with otherworldly abilities. Does that mean that Jessica herself will be pulled back into hero superhero orbit?

The short answer is probably yes, considering "Jones" is one of four planned Marvel series that Netflix is using to launch a team-up, "The Defenders." Luke Cage (Mike Colter) is dropping in on "Jones" before heading off to his own standalone series.

In the images that Netflix released, we see Jessica, Cage, David Tennant's villainous Kilgrave, Jessica's BFF Trish "Patsy" Walker (Rachael Taylor), and powerful potential ally Harper (Carrie-Anne Moss). While none of the photos really give anything away, they do set a somewhat serious, grim tone for the series -- there's nary a smile among the bunch.

Check them out and look for clues to the secrets of "Jones" below. "Marvel's Jessica Jones" debuts on Netflix on November 20.
