Do people walk around Cybertron as protoforms until they decide to take on a pre-existing form? If not, how do they take on forms that aren't pre-existing? Do they ever shed their current form and take on another, or shed it completely? How does that work? Isn't it a cop out, going all the way back to More Than Meets The Eye, to simply have some kind of energy morph someone into a new form? Are the characters first appearing in Beast Wars and Armada considered protoforms? If not, does that mean all protoforms are gray and skeletal?
