So far, one thing that the DC Extended Universe lacks is an equivalent to the Marvel Cinematic Universes big bad Thanos a lurking threat in the background to help the overarching arc of the shared universe along. Every time Thanos pops up even for a seconds-long post credits sting - the internet explodes in reaction. DC, surely, will want to get in on that. The easiest way to achieve this would be for DC Entertainment/Warner Bros to bring in their own massive supervillain. Darkseid a godlike creature from the comics, who constantly threatens to destroy planets and take over the universe - seems like a logical choice. In the comics, Darkseid predated Thanos and actually inspired his creation. As Lex Luthor is the most prominent villain in Batman V Superman: Dawn Of Justice, the easiest way to introduce Darkseid or another overarching baddie would be to reveal that Lex is in their employ. Maybe thats how Lex gets hold of Kryptonite, learns about Zods corpse and manages to create his big grey monster. Should this turn out to be the case, it wouldn't be unprecedented - itd be a similar arrangement to Loki working as Thanos lackey in The Avengers, or Ronan doing his bidding in Guardians Of The Galaxy. So maybe don't rule out a Darkseid-unveiling credits sting just yet.
