Cybertronian

The Cybertronians are a faction in the Generation 2 portion of the Generation One continuity family. They're sometimes referred to as Second Generation Decepticons or some variation thereon.

The Cybertronians were a result of Decepticon rediscovery of Bio-Morphic Reproduction ("budding") ~4 million years ago on Cybertron. The Decepticons were able to rapidly expand their population using this method.

These new Decepticons left Cybertron in the hands of petty warlords unfit for the future empire and took to the stars to conquer other worlds.

In the modern era, the Cybertronian Empire has adopted an aggressively expansionist stance. They claim to have advanced their society beyond the need for war, but hold little regard for non-Cybertronian lifeforms. Under the cause of improving the quality of life for their citizens, they have conquered many worlds, enslaving or exterminating the native population and cyberforming the planets to create "little Cybertrons."

This was apparently under the direction of the Decepticon progenitor known as the Liege Maximo, who rules them from the planet-spanning structure known as the Hub, which harnesses the networked power of the cyberformed planets. The construction of this network was later revealed to be part of a gambit by the Liege Maximo to ascend to the plane of the Dark Gods.
