Me and a couple of TF fan friends endured DOTM dvd last night, and as usual, not pleased with the massive decepticons dead count. Well, that's not actually the issue.
We've noticed most of the Decepticons had their heads destroyed in order to kill them. So we started pulling together a theory that the US governement might salvaged their headless bodies for a "Headmasters" project. Since the event of Sentinel Prime showed how they're helpless without a Cybertronian aid, the government may secretly came up with this project. I mean, so far, the US haven't been giving the Autobots the warmest of hospitality.
Think it is possible? I think it could, since slowly the movies are trying to incorporate elements from the comics/cartoons bit by bit, e.g..Pretenders, Sun Harvesters, Space Bridge etc. They bound to use headmasters in some point. Just the question of how though.
Personally this would give the Autobots a different type of enemy to face. At least not Megatron again.
