Marvel editor Mark Paniccia has dedicated Mondays as #XMenMonday on Twitter, taking time to answer fan questions regarding the publisher's X-Men themed line of ResurrXion comics. While much of the banter consists of good-natured banter between the editor and readers, when a fan asked if anything was planned after Astonishing X-Men's initial 12-issue run, Paniccia's response was fairly a pretty big deal.

What "significant and 'new'" means, exactly, and how it will shake up the current X-Men landscape remains to be seen. However, the series' villain, at least for its initial arc, will be the Shadow King, who was also the antagonist on FX's Legion. Perhaps his battle with the X-Men will leave mutantkind in a precarious situation. It is also worth noting that Paniccia put quotation marks around the word "new" in his response. That may be a clue idicating, perhaps, that another New X-Men series may spin out of Astonishing X-Men's finale.

The Astonishing X-Men series is a part of Marvel’s ResurrXion initiative, which puts both the X-Men and Inhuman groups on new paths. Astonishing X-Men bears the same name as the series that began in 1995, which has been occasionally rebooted. The debut incarnation of Astonishing X-Men was a limited run four-issue series that took place aside the alternate universe Age of Apocalypse storyline. The title was resurrected in 1999 for a three-issue series which focused on a diminished X-Men team protecting the Mannites.

The series would not see regular publication until 2004, when Astonishing X-Men was helmed by filmmaker Joss Whedon and artist John Cassaday. Warren Ellis was put in charge of the series as of 2007. Astonishing X-Men ran until 2013.

Astonishing X-Men #1, written by Charles Soule and featuring art from Jim Cheung is slated for release on July 19, 2017.
