When CHUG figures were being released, sometimes the instructions would show a different head on the figure, like a "easter egg" foreshadowing a future remold. i.e. - Thunderwing showing the future remold into Black Shadow. I'm trying to remember how many were foreshadowed, but haven't actually been released? the only one I can remember was the Perceptor mold, which seemed to show a Reflector head? are there many others like that?
