Director Zack Snyder recently confirmed that the third Mother Box will be featured inJustice League, and that it will be none other than Victor Stone, a.k.a. Cyborg. There have been plenty of rumors swirling round the Mother Boxes and how they fit into the story, especially after theBatman v Superman: Dawn of Justicedeleted scene that featured Lex Luthor (Jesse Eisenberg) using Kryptonian technology to create a vision of the villain Steppenwolf holding three Mother Boxes. DirectorZack Snyderalso offered more details about bringing this team together inJustice League.

Zack Snyderconfirmed that Cyborg is the third mother box in the print issue ofTotal Film, but this isn’t the first time he’s mentioned that particular detail. The filmmaker revealed in a March interview that theCyborgscene inBatman v Superman: Dawn of Justice, where Victor Stone’s father Silas (Joe Morton) presents his son with a strange box that turns him into Cyborg, is the “first glimpse of the Mother Box there,” adding thatRay Fisher’s character, “plays such a strong part coming up.”

Another rumor from May revealed thatJustice League will open with a flashback scene from 30,000 years ago, featuringDarkseidand his first defeat when the humans, Atlanteans and the Amazons all came together to beat him. These three civilizations are believed to have divided up an artifact into three parts, the Mother Boxes, which Steppenwolf is presumably coming for inJustice League. It has also been rumored that Steppenwolf will be the mainJustice Leaguevillain, with Darkseid appearing at the end of the movie, leading into the currently untitledJustice League 2sequel. WhileZack Snyderwouldn’t speak more about the Mother Boxes, he did discuss how bringing this team of DC heroes together was one of the most rewarding aspects of the film.

“One of the more rewarding aspects of creatingJustice Leaguewas having fun exploring the dynamic between this diverse group of characters, inherently larger-than-life characters with disparate backgrounds, ethics and unique perspectives all trying to come together and work as a team. It not only offers an opportunity for great drama and complex relationships, but it also often results in great fun. It’s an exciting concept to explore and it only gets better when you add the component of our incrediblytalented cast, their chemistry really adds to that dynamic.”

It’s possible that one of the other Mother Boxes will be revealed in the upcomingWonder Womanmovie, which hits theaters June 2, just five months beforeJustice Leaguearrives November 17. It’s also possible that the remaining Mother Box will be featured in the stand aloneAquamanmovie, which debuts August 01, 2025, before theJustice Leaguesequel will hit theaters on July 31, 2025. Hopefully we’ll find out more about these Mother Boxes as we get ready forWonder WomanandJustice Leagueto hit theaters this year.
