I think a good combination of both Lex and Brainiac would be a great way to go about the sequel.
If Zod is to represent the worst that Krypton had to offer, then Lex should be a representation of the worst that humanity has to offer; trying to cause an upheaval by breeding distrust towards Superman on the portions of the populace that are easily influenced and manipulated.
Brainiac could capitalize on how Superman's private war with Lex is causing disunity on Earth, with one group siding on Superman's side, while everyone else siding with Lex.
Now assuming if this isn't done with Zod at first in MOS, Brainiac could come with the promise of helping humanity as Superman did, but shows his true nature, thus making more people think that Superman is just as capable of turning on them like how Brainiac did.
