For millions of years, the legend of the Thirteen Primes has been buried beneath the ruins of Cybertron. Long before the war between the Autobots and Decepticons, the Primes were created by Primus to protect the balance of the universe against the chaos of Unicron. But after a devastating betrayal among the Primes, their existence faded into myth.
When an ancient Cybertronian relic known as the Omega Core is discovered on Earth, its awakening sends a powerful signal across the galaxy. Optimus Prime and the Autobots race to protect the relic before Megatron and the Decepticons can claim its unimaginable power. However, both sides soon uncover a terrifying truth: the Omega Core is actually a seal imprisoning Unicron’s consciousness.
As forgotten Prime warriors begin to reawaken, Optimus learns he is connected to a prophecy that could either unite the descendants of Cybertron or destroy them forever. Forced into an uneasy alliance, Autobots and Decepticons must confront ancient enemies, lost Prime legacies, and the true origins of Cybertron itself.
In a war that spans planets, dimensions, and time, the fate of all Transformers will be decided by the return of the Primes.
