If you haven't seen Batman v Superman: Dawn of Justice yet, there will be plenty of SPOILERS below, so read on at your own risk. Even if you haven't seen the movie yet, you most likely know that this long-awaited superhero adventure helps set the stage for Justice League Part 1, which starts shooting next month in the U.K. The movie introduces three new "metahumans," Aquaman (Jason Momoa), The Flash (Ezra Miller) and Cyborg (Ray Fisher), but it was the final scene with Cyborg that had many fans scratching their heads. Entertainment Weekly recently spoke with Zack Snyder, who helped explain this scene that essentially provides an origin story for Cyborg.

We get introduced to Aquaman, The Flash and Cyborg when Bruce Wayne (Ben Affleck) hacks into Lex Luthor's (Jesse Eisenberg) database, discovering files on all of these metahumans, along with photos of Diana Prince (Gal Gadot) that date back 100 years. Cyborg's footage is most intriguing, featuring Dr. Silas Stone (Joe Morton), lamenting over not being able to fix his son. However, another clip shows Silas presenting a strange box, which transforms his son Victor into Cyborg. Zack Snyder confirmed that this box is actually the Mother Box. Here's what the director had to say about this scene.

"That's the first glimpse of the Mother Box there. It was an agonizing birth. I really wanted to show Cyborg's birth because I feel like he plays such a strong part coming up, and I really wanted to give a sense of him. I really want [the audience] to know how far he's come."

Jack Kirby created The Mother Box as part of his Fourth World series for DC Comics. These devices were essentually "alien supercomputers that could manipulate time, space, reality, anything it wanted". These boxes would attach themselves to a host, granting their host superhuman powers. In the comics, Cyborg was described as a "technopath," who communicate with and manipulate any form of technology.

It's also worth noting that Warner Bros. released a deleted scene earlier today, which featured Lex Luthor in the Kryptonian ship, using this alien technology to create an unknown creature that appears to be holding Mother Boxes before soldiers advance and haul him away to jail. We don't know for sure if these Mother Boxes will play into the over-arching story of the DCEU into the future, but hopefully we'll find out more soon. Zack Snyder will start production on Justice League Part 1 next month in the U.K., but it isn't known when the Cyborg movie, set for release on April 3, 2020, may start production.
