3) Darkseid
If you know your DC comics, Batman V Superman presents a lot of heavy hints that Darkseid will be the big bad of the Justice League films.
In the Mad Max-esque Knightmare sequence, for instance, an Omega symbol can be seen in the sand – in other words, the symbol from which Darkseid draws his power. Likewise, the winged creatures that are flying around hugely resemble Parademons, the big guys’s henchmen in the comics.
Another reference to the Ruler of Apokolips occurs in the footage of Cyborg’s creation. The strange device that binds to Victor Stone is the Mother Box, a mysterious cosmic object that has healing powers and is tied in with Darkseid.
Likewise, a deleted scene that can be seen above sees Luthor apparently communicating with a hologram of a hideous alien creature before being arrested. Though there’s no confirmation from the studio on the matter, it’s widely believed that the creature is Steppenwolf, one of Darkseid’s generals.
Say, you don’t think they are trying to hint at something with all these references, do you?
