now I know what you are going to say, "There is no difference between ROTF head and DOTM head, Same shape and crown." Think again. If you compare, ROTF Soundwave head looked like he had a face plate and he talks like he has pincers. While the DOTM Soundwave head had a mouth with teeth. Now what's the big idea giving Soundwave a mouth? Soundwave never had a mouth ever.
