As the Greek God of War, Ares has always made sense as the villain for this particular Wonder Woman film as a DC villain that draws power from death, destruction, and conflict.
Of course, the initial report from Batman News will remain unconfirmed until Ares is actually revealed or official information is revealed about Wonder Woman’s villain.
It’s possible that Huston and Thewlis are both playing the main villain and that Huston eventually transforms into Ares at some point in the film.
Ares has been semi-confirmed as Wonder Woman’s main villain ever since a DC toy line revealed action figures that came with extra pieces to build your own version of the villain.
