I think a lot of people are going for the tried and true origins of Galvatron, but one thing I have noticed about the movies, is that they pull inspiration from different sources to create some mashup interperation of a certain character. I've been thinking perhaps, Galvatron is not exactly we would predictably imagine to be. In the Marvel comics, Galvatron was more or less a separate character, a time traveler and in other comics he was made out to be a separate ancient character, especially in IDW. Another time traveler in TF lore is Vector Prime who happens to have a circular chest piece similar to what AOE Galvatron has. Supposedly, the leaked early draft script for TF4 had a Vector Prime character who was a time traveler. So what if AOE Galvatron was some ancient time traveling transformer, like a Vector Prime character found by humans and revived by the humans, but later gains control. Once in control of himself and gathers an army of Vehicons he searches for the "key" which has some power that he needs. Whatever Galvatron's fate is, Optimus Prime becomes the time traveling Transformers suped up in his silver deco and bids farwell. Thoughts?
