Marvel Studios drew mostly positive notices for Daredevil, the first of its harder-edged, street-level superhero series launched on the Netflix platform - but it was the follow-up, Jessica Jones, that wound up really blowing critics and audiences away last November. With that hit series already renewed for a second season and the continuation of Daredevil set to hit in March, attention has lately turned to the question of when the highly-anticipated third planned series - based on the adventures of Jones' super-powered ally and sometimes lover Luke Cage, would finally hit screens.

Now, we may know the answer. The official Jessica Jones Twitter feed has posted a teaser image that seems to depict a set of files on Jessica's work desk, and one of them bears a cryptic label reading: "Cage: November."

CAGE NOVEMBER

Thus far, the notoriously secretive Marvel has revealed little about plans for the Luke Cage series, other than that it is indeed happening. Fans last saw Cage (Mike Colter) departing Jones to explore unanswered questions of his own, and the Luke Cage series will pick up with the title character a few months later, in the Marvel Cinematic Universe version of Harlem. However, the show is also expected to reveal the origin of the hero's powers - which include bullet-proof skin and unbreakable bones - via flashbacks as well, similar to how Daredevil and Jessica Jones explored their namesakes' origins. In the Marvel comics, Cage was a wrongly-convicted prisoner who gained his abilities after volunteering as a scientific test-subject while incarcerated - and while it his not confirmed that the MUC version of Cage will share an identical origin, a mystery surrounding a shady biochemical corporation and strength-enhancing drugs was a prominent subplot in Jessica Jones season 1.

Created by Marvel in the 1970s as part of a company-wide push to include more diverse characters in their superhero ranks, Cage declared himself "The Hero For Hire" upon gaining his superhuman abilities - meaning that, unlike other superheroes, his services had to be purchased (most of the time.) The character gradually evolved into a more prominent place in the Marvel pantheon, for a time adopting the moniker "Power Man" and teaming up with the martial-artists and soon-to-be fellow Netflix series lead Iron Fist to form a superhero tag team. In the early 2000s, he returned after a long absence as a supporting character in Alias (the book that birthed Jessica Jones) and ultimately became one of Marvel's top heroes and a founding member of The New Avengers.

LUKE CAGE CLASSIC

Whatever form it ultimately takes, Luke Cage will be the next to last "solo" debut for Marvel's first wave of Netflix heroes. Next up is Iron Fist, after which the various characters and their allies are set to unite as a team for a combined series tentatively titled The Defenders - though recent rumors have suggested that a fifth series based on The Punisher could also now be in the offing (based on actor Jon Bernthal's portrayal of the vigilante in the second season of Daredevil). Cage's series is also set to feature appearances by other Marvel characters from the comics and adjacent Netflix series, including Rosario Dawson reprising her role as superhero-sympathizing nurse Claire Temple and Simone Missick as Misty Knight - a Harlem police detective, who in the comics eventually becomes a super-powered crime-fighter herself (with aid of bionic arm designed by Iron Man's Tony Stark).

While there do not seem to be any Defenders clues in the teaser image, it's possible that it could be offering subtle hints about the future of Jessica herself: A second visible file is labeled "Hope: Missing," possibly a reference to Hope Schlottman, a character from the first season. More ominously, the scene is bathed in an eerie purple glow, the color associated with Jones' mind-manipulating arch-nemesis Kilgrave.
