The comic Cataclysm #0.1. is seen solicited from Marvel for October with an unknown creative team and a unknown description.
It seems as though this issue maybe the introduction to the event which should be something worth picking up knowing that Cataclysm marks the end of the normal Ultimate lines as everything is then marked as tied into the Cataclysm event.
While the description is mostly unknown, Marvel has let retailers know that Cataclysm #0.1 is, at least, written by Joshua Hale Fialkov, with a cover by Paul Renard. Joshua Hale Fialkov says it’s one of his favorite scripts this year and he really hope you guys check it out. Also hints at It having a favorite unseen for a while character in it, and is a really dark, pretty story.
