Wonder what happened to knock all the Decepticon & Autobots into stasis hibernation for decades, centuries or eons on the moon? Did Shockwave show up with some "Power Source" ray, energy field etc to "jump start" all the transformer tech lying inert on the moon? It looked like there were some Autobots trying to jump and miss Decepticon ships leaving the moon? The blue energy beams were everywhere. Even clustered around buildings? Did Shockwave jumpstart some earth Decepticons to new life with AllSpark type energy similar to the Dewbot in TF1 ? There was a spidery looking building with energy swirling around it. A modern building would have enough metal and electronic equipment inside to provide the basic elements for a transformer. Hence the birth of the "building crusher?
