The reveal of the villain was kept hidden from the press on the set tour, but we saw what he’d look like on screen, and it was very similar to the Communion scene that Zack Snyder released the week after Batman v Superman: Dawn of Justice came out.
When we visited the set of Justice League, we learned that Batman (Bruce Wayne) will continue to recruit metahumans following the “death” of Superman (Henry Cavill), and will also have to fend off parademons who are seeking three Mother Boxes that are being sought by Steppenwolf.
