bring us these two teasing images of the titular big bad The Fallen
from Transformers Revenge of the Fallen toy, along with his instruction booklet. You can see the images by clicking on the title bar.
The Fallen transforms into a Cybertronian spaceship mode. He is most likely a Deluxe or Voyager Class figure, given the size of the screw holes and the missile launcher on his right arm, seen more clearly in the second image.
