7. Steppenwolf is the main villain
When a rumour did the rounds a few weeks ago claiming that Apokoliptian general Steppenwolf would be the main villain of Justice League, many were sceptical. Surely it would make more sense for his boss, Darkseid, to be the big bad? However, the set visits confirmed that Steppenwolf will indeed be the film’s primary antagonist. A CG creation rather than motion capture, a voice actor has yet to be cast.
Steppenwolf would previously have been set up in BvS, if a scene where Lex Luthor seemingly chats with a hologram of him had not been cut out (watch it above). The winged parademons that Bruce sees in an apocalyptic dream sequence in that film will also feature.
Though there has been no official word on this, we would put money on Darkseid turning up for the film’s big third act, in a similar manner to Doomsday in BvS.
