Luke Cage has been cancelled by Marvel, according to series writer David F. Walker. Walker confirmed the cancellation on Twitter after the title was not included in Marvel's March 2018 solicitations.
"Sad but true...Luke Cage (the comic book, not the TV series) has been cancelled," Walker said. "Issue #170 is the last (and best) of the series. Oh well, on to other adventures. Thanks to everyone who supported the series."
"Time to get real," he continued. "Luke Cage was cancelled because it sold poorly. Very poorly. There are various factors that contributed to those poor sales, but they all add up to the same conclusion. The success of superheroes in film, television and video games only carries over to comics when people actually buy the comics. Truth is not many people buy comics. Of the top 10 best selling comics in November, only four sold more than 100,000 units. That's sad."
Luke Cage #170 is scheduled for a February 21 release.
