Transformers has alot of unique characters, all fighting a war. And there rarely ever been grunts or generics fighting the war (with some exceptions.) The Decepticons are known for grunts and vehicons, and their shown to have their own will and wants. They aren't empty husks. The Autobots are less frequently been depicted with grunts (either because most of the time their more Autobots than Decepticons or to give them something to fight.) But they do have them from time to time. My question is... Why are some characters generics? How does one become unique, and not all share the same body type? Are they born like that? Yes, there are many characters who share the same body type, but are unique by head or color. But the grunts are all depicted with the same body type, colors, etc. With the only thing shown to make them unique is the voice or size.
