Costume designer Michel Wilkinson sat down with Brazilian entertainment site Omelete to shed light on the winged aliens that appeared in the recent "Batman V Superman" trailer.

Wilkinson claims that the desert scene where Batman is outnumbered by Superman soldiers comes from Bruce Wayne's nightmare of a future where Superman rule the Earth.

"Zack had a great idea of this sort of nightmare-ish vision, almost a vision of the future, a post-apocalyptic vision," Wilkinson explained. "It's like a dream that Ben has, so we wanted to, it has almost a Mad Max quality to it where it's like the end of the world, trying to survive and then of course Superman and his minions come, so it's sort of a way of representing the amazing amounts of, the sort of obsessive quality that Bruce Wayne has about the threat of Superman."

According to Screen Rant, the action figure of the trenchcoat-wearing Batman which first appeared at this year's New York Comic-Con has been dubbed by the studio as "Knightmare Batman," confirming Wilkinson's claim.

The recent "Batman V Superman" trailer also marks the first time all three Justice League heroes (Batman, Superman and Wonder Woman)  appear in a scene together. Wilkinson teased that another Justice League member will appear in Zack Snyder's film.

"I'm not really at the liberty to talk about The Flash right now, but it's something that you'll be seeing in the future in our films. You do get a glimpse of him, of course, in 'Batman V Superman,'" he gushed.

The movie features Ben Affleck as Batman, Henry Cavill as Superman, Gal Gadot as Wonder Woman, Ezra Miller as The Flash, Jason Momoa as Aquaman, Jesse Eisenberg as Lex Luthor, Jeremy Irons as Alfred Pennyworth, Jeffrey Dean Morgan as Thomas Wayne, Amy Adams as Lois Lane, Laurence Fishburne as Perry White and Diane Lane as Martha Kent.

"Batman V Superman" releases on March 25, 2016.
