Chapter III: The War of the Primes

Approx. 4 billion stellar cycles ago:

In the aftermath of the Unicron Battles, the Thirteen Primes, with the aid of the Knights of Cybertron as their vanguard force, begin to rebuild Cybertron from the devastation caused by Unicron and lead its surviving people into a bold new era. Like the time before, this era was prosperous with even greater cities and technology, but it lacked the innocence of before. Due to their close proximity with Unicron during the battle, each of the Primes was corrupted by a touch of his darkness, some more than others...

Prima grew more detached from his siblings, considering himself, Vector Prime, and A-3, being the first created by Primus, as a united force of lawful good, and looked upon the other Primes (excluding Arisen) as chaotic and potentially evil. Liege Maximo looked up to the stars with hunger, seeing planets and resources ripe for conquest and domination. Megatronus Prime took notice of his more beloved brethren and envied them for their glory, seeing himself as the mightiest amongst the Primes.

During the reconstruction period, Megatronus Prime falls in love with Solus Prime, though she doesn't initially return his romantic affections. Her deep friendship with Nexus Prime, Onyx Prime, and Amalgamous Prime begins to fester jealousy within Megatronus, fueling the hidden darkness within him.

Things begin to become even worse when Prima attempts to assert his authority over the other Primes in an attempt to bring them to a united purpose to stop their growing division, only succeeding in alienating Megatronus Prime, who refuses to bow down to his older brother, leading to a confrontation between the two that involving Prima threatening to attack Megatronus with the Star Saber. In the aftermath, the other Primes remain undecided, while Vector Prime and A-3 continue to stand by Prima.

It doesn't take long for Unicron's influences to slowly convince most, if not all, of the Thirteen to believe that the Cybertronian race was inherently superior to all other races in the known universe due to their powerful artifacts and great historic feats. So, eventually, the Primes sought to spread Cybertron's "enlightenment" through the doctrine of "Pax Cybertronia" ("Peace on Cybertron"), by conquering other worlds and shaping them into "Primus' image" with the power of the Omega Lock, completely abandoning their rule of cyberforming planets with life. Distant worlds discovered by the Skyraiders like Caminus, Devisiun, Prion, Arduria, Carcer, Junkion, Lithone, Gigantion, Neutronia, and Quintessa are aggressively cyberformed, displacing (and in some cases, killing off) the planets' original organic inhabitants.

As they were fascinated by organic life and became increasingly disgusted by their actions, Micronus Prime, Onyx Prime, Quintus Prime, and The Arisen would separate themselves from their siblings' plans of expansion and live in seclusion back on Cybertron. However, Quintus Prime is approached by Liege Maximo, who has become more manipulative and self-serving by Unicron's manipulations, to secretly experiment with the life-giving powers of the AllSpark to create new forms of Cybertronian life to defend Cybertron and its colonies from any hostile aliens.

The remaining nine Primes attempted to colonize Antilla, a peaceful planet that orbited a black hole near the galactic center, home to the Antillan species. When the Cybertronians set foot on Antilla for conquest, the Antillans fought back against the robotic invaders, but they were unable to match the power of the Primes and the Titans. However, the Antillans gained the upper hand in the conflict when several of their people's best scientists created a device known as the Talisman. They activate the Talisman, which unleashes devastating waves of energy that not only decimated the Cybertronian expeditionary force but also killed Amalgamous Prime during the battle, ending the Cybertronian/Antillan War.
