This thread is my personal opinion on why the comic book character known as "The Fallen" won't appear in Revenge of the Fallen. 1. Lots of things "fell" in the first movie which the title Revenge of the Fallen could account for: a. Sector 7 b. 75% of the Decepticons c. Jazz d. Sam 2. "The Fallen" is a little known character from a comic book that the average movie goer will have no idea who it is or why he is in there. 3. There will already be at least 20 new characters in ROTF. Even if the movie is longer then the first one I could see the bots story becoming incredibly bland already. 4. Neither Bay nor Orci have literally said "The Fallen is the main enemy in ROTF" More reasons will be added as they come to mind.
