“Developing a Marvel property has been a top priority for the network — and we are so pleased with how Matt Nix has led us into this thrilling universe,” said David Madden, president, entertainment, Fox Broadcasting Company. “There’s comic book adventure, emotional and complicated relationships and a rich, existing mythology from which to draw. With the brilliant production crew behind this project, it has all the makings of a big, fun and exciting new series.”

The project would mark the first Marvel series at Fox, which has had success in the comic book genre with “Gotham” and “Lucifer,” both of which hail from DC Comics. The network recently put a “Hellfire” series from Marvel into development, but Variety has learned that project is no longer moving forward.

Loeb, Marvel’s head of television, added: “Marvel Television is thrilled to be co-producing with 20th Century Fox Television on our first project. Matt’s a huge fan of ‘X-Men’ and his take on ‘X-Men,’ with its rich characters and high-stakes adventure, is exactly the show we want on Fox. It’s a great team of creative producers who will be making something entirely unique.”

As for other Marvel properties, the studio has a large presence on broadcast, cable and streaming with ABC’s “Agents of SHIELD,” Netflix’s “Jessica Jones” and “Daredevil,” plus new upcoming shows “Luke Cage” at Netflix, Noah Hawley’s “Legion” at FX and “Cloak and Dagger” at Freeform.
