Re: Who should be the villain in the sequel for Man of Steel?
I really think if written correctly this would not be too many villains. Lex, Metallo, and Brainiac.
I'll restate my now 10 year old idea of manipulation for this gang together. Lex manipulates Corben creating Metallo, and Brainiac manipulates Lex taking over Lexcorp. Then you have a Superman and Batman vs Brainiac and Metallo ending.
