New 12-issue Metal Men series written by Dan Didio & Shane Davis.

Synopsis
With nods to early DC Showcase stories, where the Metal Men first appeared, and DC’s long history of science fiction storytelling, the Metal Men discover a warehouse of old robots, older versions of themselves, that are junked and apparently left in disrepair by their creator rather than being rebuilt after their heroic battles. Meanwhile, a mysterious liquid Nth metal has appeared in the science site at Challenger Mountain…the same Challenger Mountain that came through from the Dark Multiverse and landed in Gotham at the end of DARK KNIGHTS: METAL and was the focal point of the DC New Age of Heroes miniseries NEW CHALLENGERS.
From the Press release :
Didio revealed the concept:

I’m a longtime fan of the Metal Men and had a chance to write them briefly in the anthology, Wednesday Comics, several years ago. With this new series, we explore the essence of what makes the Metal Men human, by having them caught between Doc Magnus, the man who created them, and, the newly introduced, The Nth Metal Man, the being that gave them life. What I’m enjoying most about this book is the chance to stay true to all existing stories, while building out their mythology in exciting new directions.

With Davis adding:

I introduced Superman to a new generation in Superman: Earth One and heard from fans that they truly cared about our perspectives on Clark Kent and Superman. Dan and I have a goal on this new Metal Men series to give everyone a quality, entertaining story riffing off modern sci-fi narratives in a way that can only be done at DC. Hopefully fans will like our take on artificial life and find the unexpected humanity in these robots.
