The sequel series, "", began an undisclosed period of time later. At the beginning of the series, Prime was restored to a form resembling his original body. He and the Transformers found themselves caught in the schemes of a new generation of Cybertronians, led by the icy Jhiaxus, who were colonizing and cyber-forming other worlds. Plagued by nightmarish visions of a life-destroying entity called "the Swarm", Prime looked into Cybertron's past and discovered that Jhiaxus and his kind were the result of an unintentional Transformer reproduction. Their nature and intent, he found, was distilled to the purest, most unemotional form of conquest and that the Swarm was the by-product of this process. To fight this new enemy, Prime and the Autobots entered into an alliance with the recreated Megatron's Decepticons. Though Prime was eventually consumed by the abomination and destroyed, he was able to unleash the energies of the Matrix into the Swarm, purifying it. In parting, the Swarm recreated Prime in a new form, and he and Megatron set out to lead the united Autobots and Decepticons into a new age.
