In a statement, Snyder said that Metal has been planned “for as long as I’ve been writing Batman. But this is bigger than Batman. Greg and I started dropping clues during ‘Court of Owls,’ we continued through our Joker stories and we placed our biggest hints in the run that culminated with Batman’#50. And now we’re back to tell a story that breaks everything apart. This will be the definitive project of our careers. Metal takes us in an entirely new direction. Greg and I will dig beneath the surface of all the stories we’ve told to find a place of terror and twisted nightmares.”
The crossover event begins earlier this summer with prelude one-shots co-written by Snyder and James Tynion IV and illustrated by Jim Lee, Andy Kubert, and John Romita Jr.. Dark Days: the Forge will release on June 14th followed by Dark Days: the Casting on July 12th.
Despite the ominous tone of this crossover, Snyder indicated that it would fit in with the more hopeful tone DC Comics editorial has struck since the publisher’s Rebirth initiative began in 2016. Snyder says that Metal will “be celebratory, huge and crazy. I’ve said it before: I am going for out-of-control dinosaurs and lasers.”
While few details of the plot have been revealed, Snyder, Capullo, and DC Co-Publishers Dan DiDio and Jim Lee teased a few tidbits at Fan Expo Dallas this weekend. They indicated that the series would focus around Batman but would feature the Justice League in general. In a video, DiDio also teased that Hawkman, who recently died in the bluntly named mini-series Death of Hawkman, would factor into the series in a big way.
