15. X-Factor
A movie based on X-Factor has the potential to be something VERY different for Fox should they decide to continue expanding their X-Men Cinematic Universe. Though they started off as a spin-off featuring now older versions of the original five X-Men working together when the likes of Colossus, Storm and Wolverine were all introduced and took over, Peter David’s take (which focuses on the mutant detective agency X-Factor Investigations) would be far more interesting.
That series featured a very diverse team of heroes, and the detective agency is led Jamie Madrox, the villain turned hero known as Multiple Man. In some ways, X-Factor would work even better as a TV series should Fox decide to bring the X-Men to the small screen.
