Like it says on the tin.
IF Cybertron, and the Cybertronian civilization had gotten its act together instead of constantly fighting itself, and managed to reach its full potential?
Where would an optimally-evolved Cybertron stand in the order of fictional civilizations?
They're definitely not going to be on the level of the Jurai, the Ultras or the Q, and they're definitely higher on the scale than Middle Earth or the Yautja.
So. How far up the totem pole could Cybertron have gotten?
