This question has been bugging me for a while now. When a Transformer scans an object for its Alt. Mode does it have to be the same size as its Protoform or First form? I first thougth of Soundwave and Megatron and how the change size between their Alt modes, but then I started to think about the smaller bots and now I'm all confuzed. And there's ugrades, like BB in the movie.
