2. Villain(s)
Like I suggested in my previous section, wouldn't it be great if for once the villain was part of the good guys? Essentially, what I could imagine happening is that Lex Luthor could show up in Batman vs. Superman. However, he wont quite be the villain we know just yet. He could be worried by the damage this alien being has caused to his city and potentially the world. A phone call to a close business friend for advice on how to stop this Kryptonian could prove very useful. Of course, that business friend being Mr. Bruce Wayne. Once Bats and Supes have had their super showdown, Batman will start to make contingency plans for Supes and anyone else who shows up. This could be set up either in Batman vs. Superman or the start of the JLA film. In the JLA film, Lex could then play the role of Ra's al Ghul and either steal the plans from Bruce, or maybe be shown them willingly by him. Now, while Batman wouldn't essentially be an out and out villain, he would be responsible for the harm and damage Luthor could possibly cause. That's just one way they could go, of course. DC has a wealth of great villainy at their disposal, so it would be hard to screw this up...we hope. It would also make a nice change to the usual scenes of the world being blown to bits, and make us feel that the characters are in serious danger.
