In March 2015, Lemire launched Descender, a creator-owned sci-fi series with art by Dustin Nguyen, from Image Comics. Announced on San Diego Comic-Con 2014, the ongoing series follows a robot named Tim-21 through his adventures in space. The series is Lemire’s first creator-owned ongoing series not illustrated by himself. Descender ran thirty-two issues from March 2015 to July 2018. A sequel series, Ascender, set ten years after the original series, launched April 2019.
On January 2015, Sony Pictures acquired the movie rights to Descender after a competitive bidding war. Josh Bratman is producing, with Lemire and Nguyen serving as executive producers. Jesse Wigutow, writer of the Tron: Legacy sequel, was announced as the screenwriter adapting Descender in February 2016.
