Earlier saw a batch of Batman Vs. Superman rumors mention that Lex Luthor gets a hold of Zod's corpse, and also that Batman breaks into LexCorp to get some kryptonite.
Now Bad Ass Digest is adding to those rumors with mention that Lex Luthor has been gathering pieces and debris of the World Engine from Man of Steel and using them to create kryptonite. It's also stated that Zod's corpse is "the key" to Luthor's master plan of defeating Superman.
It's then said that Lex Luthor uses tissue from Zod to create something, with an image of Doomsday featured as a hint.
While the website suggests Doomsday may be the villain Lex Luthor creates, there could very well be two other possibilities (if this origin for Doomsday is used, it goes in a total different direction than the comics).
We could speculate that Zack Snyder may be having Lex Luthor creating his own "super man," i.e. Bizarro (as seen in
Mark Waid's Superman: Birthright Mark Millar's Red Son), or maybe it's possible the villain could be Metallo, as Metallo is powered by kryptonite.
It's further suggested this creature is the reason that causes Superman to team with Batman and Wonder Woman.
Regarding Lex creating his own kryptonite, this does make sense as previously Zack Snyder said no to kryptonite in Man of Steel, and as we saw in the movie, it was the Kryptonian atmosphere that hurt Superman, not "rock"; so it's possible Lex synthesizes some kind of element out of the World Engine that incorporates the atmosphere (some how).
