We're using G1 and Optimus Prime for scale. How big would a Unicron toy have to be to have it scale with CHUG figures? I know the show scales change all the time. Doesn't have to be exact, just roughly how big would this toy be? Do we even have official specs on how big Unicron is supposed to be in the movie? Can we scale him using the shot where he attacks Cybertron? Hell, do we even know how big Cybertron is supposed to be? Edit - After thinking a little more, I going to be more specific. Let's use the original G1 Optimus Prime toy for scale. For Unircon's size, let's use the scene where he picked up Galvatron and swallowed him. I've never owned the original Galvatron toy, but let's assume he's the same size as Optimus Prime toywise since they're the same size in the show.
