The Giant-Size Astonishing X-Men comic book was the grand finale of Joss Whedon and John Cassaday's landmark run as the creators of the Astonishing X-Men comic book series. In this issue, the powerlords of Breakworld bring the fight to Earth. Can the X-Men stop them from destroying the planet? Will the Avengers join their fight? What we do know is this: one of the X-Men won't walk away from this fight. The issue also includes interviews with Whedon and Cassaday.
