Batman vs Superman featured both the Batmobile and the Batwing. The upcoming Justice League movie could feature an all-new vehicle driven by The Dark Knight.
According to Heroic Hollywood’s Umberto Gonzalez (via ComicBookMovie), he says that Batman may have his own submarine in this movie since he has to spend a lot of time underwater.
The reason Batman needs a submarine in Justice League Part 1 is because a lot of the movie is about Atlantis. The Atlanteans are set to play a huge part in the movie so it appears Darkseid might be saved for Justice League Part 2 instead.
Obviously this is just a rumor, but Justice League Part 1 is set to start filming later this month. Not to mention Gonzalez has been super reliable when it comes to DC movie rumors in the past. He correctly reported pretty much everything that happened in Batman vs Superman.
However, Warner Bros. could change its plans considering how divisive Batman vs Superman was. Zack Snyder did say that he wanted Bruce Wayne to recruit all of the members of the Justice League so it’s not too out of left field for him to have his own submarine to visit Aquaman.
