Here's an idea that just popped into my head: Okay, how about this, so you have some movieverse Decepticon. He grabs his head, and there's some clicks and whirrs and next thing you know the headless decepticon is setting his head down on the ground. Of course in the process the head has unfolded into a humanoid bot. It assumes human form, either as a hologram, or via the pretender idea from ROTF. The main bot transforms to alt mode and the 'human' becomes a decepticon spy to infiltrate the Whitehouse or the military or something. Or you could do it in reverse. They're chasing down one of those pretender bots, but when it gets outside there's a vehicle transforming and the pretender jumps up and the headless bot catches and attaches it. And then later, well maybe there's a few of these guys. But anyway the thing about a Headmaster is he's much more vulnerable when detached from the main body. So maybe some of the army guys are actually able to capture one of them and kill it. But in the meantime, the main body has transformed. And it's sort of running around bumping into things like a headless chicken. Thoughts?
