Can somebody please describe how Animated Leader Megatron's head is attached? Is it a screw that you could unscrew and potentially attach a different head? If you took it off, would it ruing his alt. mode? Does it fit so snugly in his alt. mode that there's no way a different head could fit? I am considering doing a custom with which I take the head of Energon Megatron, pop off the sides of his crown and file down the crest. I doubt it, but I'm sincerely hoping his head will be able to screw on to the animated body without interfering with his transformation. Anyone know if this might work?
