There's no arguing that DC Films productions have been a few shades darker than Marvel Studios' blockbusters. Christopher Nolan's Batman films were shaped by their darker tone,

and Zack Snyder's controversial "Man of Steel" embraced a brooding Superman. Those two visions of the DC Comics icons culminated in "Batman v Superman: Dawn of Justice,

" which leaned heavily into its bleak,

"mature" superhero vision with an R-rated ultimate cut that gave viewers an even more vicious take on the Dark Knight.

Warner Bros. and director Zack Snyder appear to have attempted to brighten "Batman v Superman" somewhat with changes to the designs of The Flash and Cyborg, who appeared only briefly in that film but will play a much larger role in next year's "Justice League."

Costume and creature design firm Ironhead Studio, whose credits also include "The Avengers," "Tron: Legacy" and "The Amazing Spider-Man," has revealed unused designs for the two young heroes from "Batman v Superman."

The Flash's suit isn't much different from what we saw in the final film, but it adopts a dark, rusted metallic look reminiscent of the Scarlet Speedster's appearance in the fighting game "Injustice." Cyborg represents a much more drastic shift, with a suit that covers Victor Stone's entire face, and more resembles an advanced Terminator than the Cyborg we know from comics and animated television.

Starring Ben Affleck, Henry Cavill, Gal Gadot, Jason Momoa, Ezra Miller and Ray Fisher, "Justice League" arrives in theaters Nov. 17, 2017.
