Marvel will launch its 50-page one-shot comic by Jason Aaron and Esad Ribic, Legacy #1, in September.

It is intended to "set the stage for the next chapter of the Marvel Universe with hope, heroism, heart and the Earth-shattering return of a beloved Marvel mainstay."

Fantastic Four? Miracleman? Willie Lumpkin? Who knows….

Back at C2E2, Joe Quesada said "The Marvel Legacy initiative is a celebration of everything that makes Marvel the best in fiction and it's a signifier of a new era for Marvel Comics. It's a loving look at the heart of Marvel as we embrace our roots and move enthusiastically forward with all the Marvel characters you know and love starring in the biggest, boldest, best Marvel stories. All of which kicks off with the giant Marvel Legacy special."

The Legacy banner will be featured prominently on the covers of new and continuing series starring characters such as the Avengers, Squirrel Girl, Spider-Man, Captain Marvel, America Chavez, Deadpool, the X-Men, Ironheart, The Punisher, Ms. Marvel, Captain America, Moon Knight, the Champions, Luke Cage, Odinson, the Hulk, Iron Man and the Guardians of the Galaxy, as books return to their legacy numbering. Venom was first, Ultimates2 was next, expect more in September.

And Marvel will be sending retailers free copies of their September Previews catalogue, featuring Legacy #1, Generations, Runaways, Venomverse, and more, to match their order of Secret Empire #3.
