...Megatron! Yesterday a few prototype images of Transformers: Dark of the Moon toys were leaked online. One of them was of a tanker truck looking thing that wasn't painted so lacked the detail needed to completely verify its identity but most people assumed it was what I have been calling the "Mad Max" truck seen periodically during filming in Chicago and DC.
Later, more images were posted of the truck's robot mode that proved it is Megatron complete with cape, confirming the rumor from September. The pictures on Facebook (account required) show that half the face remains scarred (like Two-Face) as a result of the battle with Optimus from the end of Revenge of the Fallen. Where is the robot image you ask? Hasbro demanded all the various websites pull the images, more or less officially verifying this conclusion. Thanks to rumah for the link.
Update: The cat is out of the bag for Hasbro as JoBlo.com has posted the images of the robot mode. While they claim "dandy anonymous scoopers" but the same root source as above. If the three images no longer appear, probably means JoBlo either blocked my linking to them or Hasbro successfully got them to pull the pics.
