I really think in Transformers 3 or some other point in the Movie-verse portion of the TF Universe, we should definetley see some more combiners. I think based on his size Menasor would look very cool and being made up of cars (Which are smaller than Construction vehicles, obviously) ILM might be able to create a combiner than can stand up on their hind legs. I would so love to see a Movie-styled Menasor go up against Defensor. They seem to be similar in size. I'm guessing they would be around 50 feet max. standing up. Monstructor, while somewhat obscure, would proably be built like Devastator too. Superion would be incredibly massive but I don't think he would be brought in, seeing as a bot bigger than Devastator would also be physically unable to move, much less stand up. I think I could whip up a bit of fan art within the week, keep you guys updated on that. Though who should I start with? Menasor or Defensor?
