Prime (Transformers) - Transformers: Robots in Disguise

Transformers: Robots in Disguise

The Autobots are the main race on Cybertron, and their enemies are the Predacons. The Autobots fought in the Cybertronian Civil Wars, presumably against the Predacons. Vector Sigma, the Allspark, chooses which Autobot is to be granted the Matrix and thus the position of commander-in-chief. The Autobots were already on Earth when the Predacons arrived, having taken the form of Earth vehicles to work as camouflage and established a Global space bridge network and a central base monitoring the entire planet.

In their disguises, the Autobots integrated themselves into human society; Team Bullet Train worked as actual trains, X-Brawn was owned as a car by Kelly, and Optimus Prime was working for a fire department. This continued after they went public; both Prowl and Tow-Line, for example, were shown enforcing human laws in an apparently official capacity, suggesting the Autobots had official ties to human authorities. It is known that Optimus fought the Predacons on other worlds, presumably using the same tactics as on Earth.

Note that in Car Robots, there is not one singular Matrix, but multiple ones, each held by high-ranking Autobot commanders. Magnus already possesses a Matrix, and simply seeks to steal the power of Fire Convoy's to increase his own (the overspill of energy resulting in the supercharging of the Autobot Brothers).
