Every Transformer needs one. Without a head, a Transformer is no better than kitbash fodder. And likewise, every head needs to be hidden for alt mode, and brought out during transformation, whether it be a button-push, a simple flip, or a pull. And as always, there are duds. TL;DR: No head = No Transformer So what are the Transformers that have the worst head reveals? I nominate Energon Prowl, simply because his head doesn't have any set position to be in while the figure is in alt mode.
