The Els flash fly Prince Wayne in Dark Knights of Steel #7 preview

gamesradar.com:

DC's Dark Knights of Steel follows the publisher's long tradition of putting well-known DC heroes in new situations, new contexts, and new worlds (once upon a time, we called them Elseworlds, but that's a story for another time), with a medieval fantasy setting centered on - who else? - Batman and Superman. And in Dark Knights of Steel #7 (opens in new tab), Prince Wayne (the DKoS version of Batman) has a violent vision of a world overrun by Kryptonians, who the narration calls "demons" who "come from the stars."

The idea of Batman having visions of Superman going bad - or even living through that scenario - has become a recurring theme of its own in alt-reality DC stories such as the New 52-era Earth-2 comic title, and as glimpsed in the films Batman v Superman: Dawn of Justice and Zack Snyder's Justice League. 

And of course the idea of Batman facing down an all-powerful, world-conquering Superman was a long term plot in Dark Knights of Steel writer Tom Taylor's own long-running Injustice comic series, based on the video game of the same name (one of the best video game comics ever).

DC has released a set of interior preview pages for Dark Knights of Steel #7 from writer Tom Taylor, artist Nathan Gooden, colorist Arif Prianto, and letterer Wes Abbot showing the title's take on the concept of Batman's dark vision of a world overrun by Superman and his fellow Kryptonians.

Here are the pages:

There's one other interesting alt-reality component to Dark Knights of Steel #7, seen in the final page of the preview: the DKoS version of the Teen Titans, the young team usually associated in mainstream DC continuity with Batman's sidekick Robin, in this case specifically Raven and Beast Boy.
