- The Senate is a pre-war governing body of Cybertron from the IDW comics portion of the Generation One continuity family.
Known senators from this era include:
Just prior to the Great War, the Senate had grown rich and corrupt, making only conciliatory gestures to their constituents while hoarding energon and manipulating the commerce of Cybertron to their advantage. One of the main projects that had resulted from this was the increased automation of the asteroid energon mines. Sentinel Prime appeared well aware that the Senate was out for itself, and held a rather low opinion of them as a whole.
The Senate's status following the devastation of Cybertron is unknown, but things did not look good for them.
- As Megatron Origin was based on the decline of the Roman Empire, the Senate was most likely based on the Roman Senate. This tells us nothing of how the Senators were elected, however, as Roman Senators were former Roman magistrates, and since Primes appear to be lifetime appointments, it's unlikely that it's made of former Primes.
