Fiction

Age of Extinction film

Eons ago, the Creators used the Seeds as part cyberforming initiative on thousands of worlds. This led to these worlds being seeded with Transformium and which wiped out numerous species with the material being used to construct new Transformers. On Earth, the Creators arrived and conducted a similar mission which led to the Great Extinction of the Dinosaurs. The Transformium remained present on Earth where human scientists discovered it but were unaware of its true nature. This changed following the encounter with the Transformers where the scientific applications were uncovered. After the Battle of Chicago, Kinetic Solutions Incorporated was forced where they sought to mine Transformium either the deposits on their world or within dead Transformers. This saw Darcy Tyril being dispatched to find new deposits for KSI who sought to find new sources of the material. At the time, Harold Attinger of the CIA allied with the Cybertronian bounty hunter Lockdown hunting down Autobots in search for Optimus Prime to return to the Creators. In exchange for the CIA's assistance in capturing Prime, Lockdown would give them a Seed which would be given to KSI for deployment in a desert where they would mine the Transformium for a century. Unknown to them, the reborn Megatron intended to take the Seed to forge a new army of Decepticons. Ultimately, the Autobots managed to stop the Decepticon plot where Optimus took the Seed into space to hide it to prevent its power from being abused for evil. Age of Extinction

Ask Vector Prime

In Tyran 609.23-PX Kappa, Lockdown arrived on a Decepticon-controlled Earth to demand that Optimus Prime be handed over to him. When both Megatron and Sentinel Prime refused, Lockdown offered Sentinel a protomatter seed in exchange for Optimus. While Sentinel was sorely tempted by the deal, Optimus used to opportunity to reignite Sentinel's sense of justice. Sentinel proceeded to pretend to hand over Optimus, ambush and defeat Lockdown, and capture Lockdown's ship. Allying themselves with the Dinobots, Sentinel and Optimus waged a long guerilla war against the Decepticons, eventually restoring freedom to Earth and revitalizing Cybertron with the seed.
