Dynasty of Primes

The Dynasty of Primes (プライム王朝, Puraimu Ōchō) was the ruling class of Cybertron eons ago. Formed by the first Cybertronians, the Dynasty ruled Cybertron and protected the AllSpark until they were betrayed by one of their own.

The only named Primes are Prima, the first Prime, Sentinel, who remembered his ancestry, Bendy-Bus, whose status is unknown, and Optimus, the last of the Primes.

History
According to Jetfire, the Dynasty of Primes was formed by the first Seven Cybertronians. These beings could not transform, but they and their transforming descendants possessed powers beyond that of the average Cybertronian. The Dynasty ruled Cybertron and protected the AllSpark, replenishing it with the energy harvested from stars. However, the Dynasty of Primes was also benevolent, believing that all life was sacred, and refused to harvest stars with worlds inhabited by sentient races. To better prevent abuse, the Dynasty guarded the Matrix of Leadership, an artifact formed by the AllSpark to power the Great Machines used to harvest stars. However, one of these Primes believed that they should harvest the star Sol, which promised to yield vast amounts of energy, even though Sol was orbited by a small world with primitive inhabitants, humans. After this plan was unanimously rejected by the others, the others stole and hid the Matrix in the Tomb of the Primes on Earth, fusing it shut with their own life essences. The Fallen, as the renegade Prime was now known, dispatched the Seekers to retrieve the Matrix, but they were unsuccessful and eventually abandoned. On Cybertron, the Fallen hunted down and killed every last Prime he could find, knowing that they were a threat to him. A single orphan was hidden away with no knowledge of his lineage: Optimus Prime.

In time, The Fallen encountered Megatron, and directed him to form the Decepticons, promising him the powers of a Prime in exchange for his loyalty.
