Written by Jed MacKay, the five-issue X-Men storyline officially kicks off in September with DNX #1, and its ending will pave the way for a new Marvel era. In the storyline, the X-Men will face off against the clandestine group 3K, which wants to forcibly transform all humans into mutants. Starting in X-Men #35 as a prologue, the crossover will require readers to follow multiple issues of X-Men, DNX, and Fantastic Four comic books.
