Re: Who should be the villain in the sequel for Man of Steel?
What if it follows the bat trilogy paradigm?
Film 1: Zod. Essentially Supes' version of Ra's Al Ghul. A ruthless military villain with connections to Superman's past.
Film 2: Brainiac. Essentially Supes' Joker. An intelligent enemy that can outsmart Supes for much of the film and really play mind games with him, offering him all that he knows about Krypton. Inhuman and cold, he's the opposite to Supes' warm humanity.
Film 3: Luthor / Doomsday. Essentially the TDKR story. Luthor unleashes Doomsday (Bane) on Supes, a big physical threat, and Supes is "killed." Luthor creates a puppet clone Superman which he uses to keep power in Metropolis, until Superman's unexpected return.
