So after viewing Man of Steel i was thinking of where we go from here story wise:
1) With the state that we left Metropolis in i think that a logical train of thought would be to add Lex here. In the comics he claims to own half of Metropolis, so here is the opportunity to show Lex, finally, as the Billion Dollar CEO that he is, to show his influence and his importance in Metropolis. He could come in and rebuild the leveled city in MOS 2. This could create a platform for him to run for presidency. And if so, i dont think that he should be elected until the Third installment or between films 2 and 3 which could set up an interesting viral marketing campaign. Along with Lex being the antagonist in the second movie i feel like there should be another villain ......
2) Bizarro.
With the emergence of a Kryptonian on Earth, the logical response is to find a way to control this force or create a controllable force to match it. I can see Luthor funding research to clone Supes, resulting in an imperfect clone, Bizarro. I also think that Metallo could work as well in the same way.
3) Braniac, He could come to earth with the intent to do what Braniac does. Lex could team up with Superman to stop him, also aiding him in his campaign. But of course Lex has his ulterior motives. If Braniac isn't used and we go the Lex/Bizarro route or the Lex/Metallo route, then Braniac could be used for the third/final installment. Which brings me to ......
4)The God of Apokolips, Darkseid. He may or may not be used for Justice League, but if not, MOS 3 is a MUST. This is the KingDaddy of all superman villains. If he is used for JL then Braniac should be saved for MOS3
5) I feel like Supes should don the GodFall suit at some point in the final installment. wether its Braniac or Darkseid it could easily fit into the story, with the suit being black it helps him to absorb sunlight.
6) The Prequel Comic to MOS introduces us to Kal-El's cousin Kara, Supergirl. I don't know if this means that eventually she will play a part in the on screen world of MOS, but personally i don't think that her presence is needed. I think we've seen enough Kryptonians on screen. Our world is set up, let's branch out a bit
Would love to hear your ideas of where the story should go from here, leave your comments below.
