Question: During the second movie we see many Autobots, Tex Two Idiot Robotwins and some Motorcyclebots. But now it are only nine Autobots again in the movie. Where did the other Autobots went? Did they got killed or went in hiding?
Question: How did the Decepticons bring something as big as the Driller on Earth unnoticed? It's an earthworm the size of a building. Also, Megatron got here on purpose, Sentinel got here by accident, so did the original Seven Primes, so that would be an extreme number of coincidence. And even if that thing had been here for all these years, how did it manage to stay hidden? It's not like it can transform into something a little more subtle like a car.
Question: Mearing says that the Xantium brought the second wave of Autobots. Which wave does she mean? Because so far, there have been three waves: Optimus, Jazz, Ironhide, Bumblebee and Ratchet, Sideswipe, The Twins, Arcee, Chromia, and Flareup and lastly, The Wreckers, Brains, Dino and Wheeljack. Which one didn't arrive by ship, and how did they arrive?
Question: I understand that the Autobots conveniently landed in America, but why do they only side with the Americans in their missions? There's a scene where Optimus and Sideswipe go on a mission to the Middle East. I just thought that Optimus and the other Autobots would've considered who was the best country to side with, not just agree to go out with the Americans.
