When the Dark Multiverse begins to invade the DC Universe inhabited by the Justice League in Dark Nights: Metal, Batman, Wonder Woman, Superman and the rest of the world's heroes stand their ground against the mysterious new threat in Dark Nights: Metal. The event's plot revolves around Nth metal, a Thanagarian element most often seen utilized by Hawkman and Hawkwoman and has numerous properties, including allowing a person to fly, regenerate from injury and more.

"The story is really about [the dark Multiverse] coming here to invade," Snyder said. "So often in these sort of stories that deal with multiverse dimensions... the heroes go in to find something. But this one's about this one attacking us. So it's very different, in all kinds of ways... It gives us a chance to invent all kinds of new stuff."

"When you're up, or things are going well," Snyder added, referring to DC Comics' currently strong sales and fan support due in large part to the ongoing Rebirth mystery," it's the best time to take risks. for us, it's about exploring new territory, which is what Metal is about at its core. It's about exploring realms that are completely uncharted and terrifying and wondrous, and a lot of that is bringing in new talent to make new books."

When Batman begins to investigate the most recent death of Hawkman, the opening events of Metal "blows it out into an entire Justice League extravaganza, where everybody sort of goes and finds out that the DC cosmos is a lot larger and scarier and wondrous than everyone thought," Snyder explained.

In addition to the artwork seen above, depicting the League armored up and apparently ready for battle, the video also teased a second piece of Capullo's art revealing that classic Superman foe, and current member of the Superman Revenge Squad, Mongul is involved in the story in some capacity.

Launching this summer, the “Dark Nights: Metal” event will kick off DC’s brand new “Dark Matter” line, which will consist of “The Silencer” by Dan Abnett and John Romita Jr., “Sideways” by Dan DiDio and Justin Jordan and Kenneth Rocafort, “Immortal Men” by James Tynion IV and Jim Lee, “Damage” by Robert Venditti and Tony S. Daniel, and “New Challengers” by Scott Snyder and Andy Kubert.

Written by Scott Snyder and illustrated by Greg Capullo, “Dark Nights: Metal” is described as the former “Batman” team’s “rock ‘n’ roll epic.” According to DC Co-Publisher Dan DiDio, the entire DC Universe is at risk in the event. “Not even just our world,” he said, “but multiple worlds at risk.” The story will examine every choice a hero doesn’t take and every path they don’t walk, opening up worlds that are forged by nightmares, and characters and stories from each of the “Dark Matter” books will be plotted throughout this series.

“Dark Nights: Metal” debuts in August from DC Comics.
