This is my first attempt at a blog post on here, so it's probably not going to be very good.
One of the biggest things that's always bugged me about the Generation 1 cartoon is that during the first two seasons, Cybertron is obviously sized for vastly more beings than the sum total of Transformers ever shown, or even named, in the entire series.
Cybertron as depicted in the 1986 cartoon movie is another matter. Sure Cybertron was depicted as considerably smaller than Earth in the first two seasons- but it wasn't depicted as THAT small. In the movie, one could conceivable have seen humans walking around on the surface. Omega Supreme couldn't have searched for weeks for the Contructicons on THAT.
