10 DCEU Theories Better Than What's In The Movies
3. A Wonder Woman Vs. Aquaman Movie
Talking of Flashpoint, the idea of Wonder Woman going to war with Aquaman is one that developed into a widespread fan theory even after it became apparent that the Flash's movie wasn't going to be a reality-altering event full of familiar faces (instead, it's been claimed that the film will just use that name and be a regular Flash adventure).
It's easy to see where this came from; Aquaman and Wonder Woman have been Warner Bros.' most successful DC Comics franchises, and combining them seems like a logical move. Justice League also revealed that the Atlanteans and Amazons have some history!
This theory claimed that with Aquaman now King of Atlantis, Diana Prince would return to Themyscira after the League was disbanded, and the machinations of an unnamed villain - possibly the aforementioned Injustice League - would lead to their two nations going to war.
If Warner Bros. had a plan for its DCEU, this might work, but their films have started becoming standalone in nature, so it's not a theory likely to ever be proven correct.
