In the barbarian age after the departure of the Knights of Cybertron, Onyx was the leader of a flock of wayward and mistreated Cybertronians, searching for whatever energon they could find. One day, they came across the time-lost Shockwave, transported twelve million years into the past as a result of the destruction of his chronal drive. The kindly Onyx offered the damaged Shockwave some of their energon and introduced himself; realizing the crucial role that Onyx would play in Cybertron's history, Shockwave took him up on his offer after killing him and seizing control of his herd. The First Who Was Named

Disguising himself as the newly-styled "Onyx Prime," Shockwave used his knowledge of Cybertronian history to ensure the perpetual dominance of the Cybertronian species, seeding history with ontological paradoxes (including the "Dark Cybertron" prophecy that his younger self would one day attempt to bring about) and the means by which he would one day find himself transported backwards in time. The Hallowing By establishing, and subsequently tearing down, every myth and legend that his fellow Transformers believed in, Shockwave aimed to destroy every faith, faction, and creed, sacrificing Cybertron itself to forestall Unicron, and uniting what remained of the Cybertronian species under a new banner—his own.
