The mechanical planet of Cybertron was once home to a thriving society of Mechanical Life Forms known as Cybertronians, led by the Primes. Unfortunately, war with an invading race called the Quintessons resulted in the defeat of the Primes, the loss of the Matrix of Leadership, and sent the survivors to live underground. The disappearance of the Matrix resulted in the loss of the planet's life-sustaining Energon, requiring it to be manually extracted by Miners, a subgroup of Cybertronians who cannot transform and are treated as nobodies as a result. When two Miners, Orion Pax and D-16, learn of a distress call on the surface, they recruit two others and travel to its source in hopes of finding the Matrix. There, they learn what really happened in the Quintesson war, acquire the ability to transform, and set out to save their world... but their journey has a detrimental impact on D-16, which will send the fate of Cybertron — and his friendship with Orion — down a more turbulent path.
