Etta Candy was the best supporting character in Wonder Woman, and an epilogue scene included in the DVD bonus features proves her role was even more important than we originally thought. The scene, released to the public by Yahoo Movies, shows Etta meeting with Wonder Woman and Steve Trevor’s allies, Sameer, Charlie and Chief Napi, to propose a new mission. This mission has a connection to Justice League and the Mother Boxes.
“It is our first mission. Top secret. The war is over but the good fight goes on,” Etta says in a bar. “So after the bombings in Leige, along the western Belgian front, the powers that be found something. It’s very old, it’s very powerful and they want us to recover and deliver the artifact and deliver it to the Americans. I mean, we don’t want it in the wrong hands, do we?”
While Etta does not come out and name the object, DC fans know she’s probably referring to a Mother Box. You can thank Jack Kirby for the creation of Mother Boxes (and wish him a happy 100th birthday). They are a sentient computer of sorts originating from New Genesis and Apokolips, home planet of the New Gods. They possess wondrous powers, like energy manipulation, teleportation (boom tubes), healing… pretty much anything the mind can conjure up.
In the DC Extended Universe, three Mother Boxes are known to exist, all originating from Darkseid’s first invasion of Earth thousands of years back (rumored to be part of a prologue sequence in Justice League featuring the Amazons, Atlanteans and humans fighting together). The war was not successful so now, one Mother Box is in possession of The Atlanteans, one with the Amazons and one with the humans. The one Etta is likely referring to is the one left to man, which is also presumably the one that created Cyborg. While the origin of these Mother Boxes has been left mostly unexplained in the DCEU, we do know STAR Labs acquired one, as seen in Batman V Superman: Dawn of Justice. Silas Stone experimented on them to save his son, Victor, and that’s how Cyborg was created.
In Justice League, Steppenwolf has come to collect the Mother Boxes and wage another war. Probably the most straightforward clue we have about Steppenwolf (some say it’s actually Darkeseid’s father, Yuga Khan) in Justice League is a bonus scene titled “Communion” from Batman V Superman: Dawn of Justice. Lex Luthor is present and the scene is 100 percent chilling. Steppenwolf appears with three Mother Boxes and disintegrates into the air.
While we know about the location and use of mankind’s Mother Box, the story behind the boxes on Atlantis and Themyscira remain a mystery. Justice League will undoubtedly answer these questions and shine more light on their powers and mythology.
