Marvel Comics today announced that Magneto would be the subject of a four issue Last Days miniseries that will begin in May with the release of Magneto #18.  The Last Days comics will sport distinctive trade dress and will narrate, what Marvel Editor Tom Brevoort calls, “the final stories” of the characters, who are facing the destruction of the Marvel universe as we know it (see "Marvel Unveils 'Last Days' Brand of Secret Wars Comics").  So far the only other comic revealed as part of the Last Days brand is Loki: Agent of Asgard.

Magneto played a major role in the first Secret Wars crossover, but at this point it is not at all clear that he will even make it to the meat of this new Secret Wars event.  In a Newsarama exclusive Magneto writer Cullen Bunn explained the narrative thread of the Magneto Last Days series, "Magneto sees the world ending.  That would mean that everything he's worked for... all the terrible things he's done... would be for nothing. He has fought to save mutants, and now everything is going to be wiped out. Magneto simply cannot allow that to happen.  He sets out to save the world, and he'll stop at nothing to do so."

Since Marvel’s EIC Axel Alonso has already indicated that the Marvel universe as we know it will be destroyed by the intersection of universes that brings on the Secret Wars event (see "'Secret Wars' Will End the Marvel Universe"), Magneto’s fate and the fate of the Magneto comic book series remains in doubt (Bunn did not reveal if the Magneto comic would continue beyond its four Last Days issues).

One character who will be appearing in the series is Magneto’s daughter Polaris, who first appeared in X-Men #49 in October of 1968, and has long been a member of the X-Men or (later) X-Factor teams, save for the period (1987-1989) during which she was possessed by an evil entity and became the villain known as Malice.  Bunn told Newsarama, "Polaris will have a big part to play in the series."
