Yeah, that's the question. From the episode "The Elite Guard", we caught a glimpse of Cybertron, the homeworld of both Decepticons and Autobots. Now, in G1, Cybertron always varied in size. In the picture of Transformers Animated, the planet almost looks like its G1-counterpart. We see giant towers, and deep crevasses. But how big have we to imagine them to be? Are these giant towers as big as the himalayan mountains? These rifts as deep as the the one in the dead sea? May the towers shown there contain vast cities the size of whole earthen nations? Or is Cybertron barely as big as one country on Earth? What's your take?
