Okay... here is the teaser image...
If you look closely you can see an Omega symbol very large on the ground. This is the symbol heavily associated with Darkseid in DC mythology.
According to several reports, this is Batman's 'knightmare vision' in BATMAN V. SUPERMAN and it looks like the Omega symbol in front of him is foreshadowing of the arrival of Darkseid (probably in JUSTICE LEAGUE). And the animated GIF below is also another tease from his 'knightmare vision' as the winged creatures (Parademons) are most likely Darkseid's minions.
Less than two months until BATMAN V. SUPERMAN releases in theaters, on March 25, and all the questions about this movie can be answered. To read more about Darkseid on DC's character page, click here.
