In a big push for more superhero content, Netflix has purchased Millarworld, the publishing outfit founded by comic book legend Mark Millar.

Known as a modern-day Stan Lee, Millar is the creative force behind a number of iconic Millarworld brands including Kick-Ass (pictured), Kingsman and Old Man Logan. Millar also spent eight years at Marvel, where he developed a range of comic books and story arcs that inspired the first Avengers movie, Captain America: Civil War and Logan.

Though terms of the acquisition weren’t disclosed, Netflix has announced it will create yet-to-be-announced original films, series and kids shows based on Millarworld’s existing fan-favorite franchises. Under the Netflix label, Millarworld will also continue to create new properties spanning the superhero, anti-hero, fantasy, sci-fi and horror genres.

Millar founded his comics publishing house in 2003 and currently operates the company with his wife, Lucy. Since its launch, the company and its co-creators have produced 18 published character worlds, of which three, Wanted, Kick-Ass and Kingsman, were adapted into movies that have a combined global box office gross of nearly US$1 billion. Millarworld properties have also found global licensing success across clothing, video-games and toys.

The acquisition follows Netflix’s partnership with Disney-owned Marvel that has delivered a number of popular superhero-based shows including Jessica Jones, Daredevil, Luke Cage and Iron Fist.

For more kid-focused superhero content, the SVOD recently ordered Hasbro’s first Netflix original series, Stretch Armstrong and the Flex Fighters.

In related comics and graphic novel business, a new joint-estimate by comic book sales repository Comichron and industry source ICv2 revealed that a larger kids and female audience helped drive sales of comic books and graphic novels up 5% to US$1.1 billion in 2016.
