The comic book in the image is the Dark Nights: Metal Omnibus (hardcover edition, published by DC Comics in January 2023), written by Scott Snyder with art by Greg Capullo, Jonathan Glapion, and FCO Plascencia. It collects the full 2017-2018 Dark Nights: Metal crossover event, including the 6-issue miniseries, preludes (Dark Days: The Forge and The Casting), one-shots featuring the “Dark Knights” (e.g., Batman: The Red Death, The Batman Who Laughs), and various tie-ins from series like Nightwing, Justice League, and Suicide Squad. It’s a hefty 1,200+ page volume with a striking foil-stamped cover featuring Batman amid the Justice League symbols, as shown.
