Noting “this is real!,” “All-New X-Men” and “Ultimate Spider-Man” writer Brian Michael Bendis posted a cover by artist Sara Pichelli welcoming Miles Morales to the All-New X-Men:
The cover to “All-New X-Men #32,” a homage to John Byrne’s cover for “Uncanny X-Men #139,” features a statement that’s become synonymous with characters joining the X-Men: “Welcome to the X-Men Miles Morales. Hope you survive the experience!”
Bendis writes both titles and co-created Miles Morales, the Ultimate Universe’s Spider-Man, who took over after Peter Parker died. A “616” version of Morales has been revealed to exist in the regular Marvel universe as well, so time will tell which version of the character will show up in “All-New X-Men.” The costume seems to indicate it’s the Ultimate version.
