In my mind, he'd have to be a John Shea kind of Lex Luthor, not anything else. Someone Superman can't come right out and attack, just shady and who gives Clark a bad feeling but can't pin anything on.
Agreed. He can't be obvious or a known criminal. I thought perhaps he could be associated with the military or government and influencing persons in power to an anti-Superman POV, maybe creating some problems and attributing them to Superman (like our Lex did with the heat). If he's sciency, he might want access to Clark's blood so engineer super solider or gain immortality/power himself. Others have recommended the idea that he plays philanthropist, contributing a lot to the rebuilding of Metropolis. Possible owns a competing media outlet? I'm curious to if he'll have a
reason to be Superman's enemy, given how well (I think) they did with Zod.
The only other possibility for Kryptonite that I can think of is the idea that it could have been accidentally formed during the attempted terraforming process.
That is an extremely intriguing idea.
ETA: I have to admit, the more I think about it, the more I like the idea of LNC watching MOS. Lois would think of the military and their plans about Supes in LNC when the military acted here. Might think about Nor. Clark would react to Zod attacking Martha. And they'd both be really impressed by the special effects. Lois would call reboot, especially after seeing Zod again. Not sure how it'd work with them watching a future made movie, though.
