This article contains spoilers for Batman: The Detective #1 by Tom Taylor and Andy Kubert.
Batman has adopted Zack Snyder's Knightmare costume in the comics, too. Auteur director Zack Snyder may be controversial, but one thing cannot be denied; his visual style is absolutely one of a kind and always something to behold. The costume designs in Snyder's DC movies are unparalleled, especially during the Knightmare scenes.
These so-called "Knightmare" scenes are set in a barren, dystopian future inspired by DC's popular "Injustice" storyline. The first Knightmare was in The Knightmare Batsuit was incorporated into DC Comics back in 2017, when Batman wore the trenchcoat and goggles when he and Catwoman were forced to leave Gotham City. But now Batman has brought it out of his Bat-closet on a mission that once again takes him out of his hometown.
Tom Taylor and Andy Kubert's new series Batman: The Detective sees the Dark Knight travel to London when he hears reports of people killing innocents in the name of the Batman. It's not clear in-universe why Batman thinks he needs a trenchcoat and goggles to navigate the British capital city, although it may well be that he feels the weather in London is even worse than Gotham. There has been one intriguing adaptation, though; the addition of another layer of pouches around Batman's waist, meaning he can probably carry double as many items in the Justice League.
It's interesting to note that, in the comics, the Knightmare costume seems to be consistently linked with dark, introspective stories in which Batman leaves Gotham City. Amusingly, the continuity in Batman: The Detective #1 is just as confused as anything seen in the DCEU; at first glance, it appears to be set after the events of "gained a new Batcave in the wake of that particular event, confusing the timeline. This is the problem with doing so many Batman books at once; continuity suffers as a result.
Warner Bros. may currently be refusing to restore the Snyderverse, but the Knightmare costume's appearance in Batman: The Detective is undoubtedly a nod of respect from the comics. Hopefully, Tom Taylor's story won't get quite so dystopian, though.
