In the war that followed, Cybertron was decimated, and eventually Optimus was forced to capture the All Spark to keep it out of enemy hands.Eventually, Prime made the decision to launch the All Spark blindly into space to put it beyond Megatron's reach.
Four years later, in 1902, the government operatives tasked to investigating this frozen "Mega-Man" discovered the All Spark in the Colorado River.
The All Spark was responsible for creating the planet Cybertron and the first entities that inhabited it, a race of massively powerful trans-dimensional beings that became known as the Dynasty of Primes.
The All Spark sustained the planet and the Primes through its continuous generation of Energon, but the Primes soon discovered its vast power was finite, and they were at a loss on how to restore it.
The All Spark was discovered beneath the city of Simfur and unearthed prompting an attack by Sentinel's most violent opponents the Thetacons.
During the battle, technical genius Wheeljack used a device to warp space and time teleporting a sun from across the galaxy into Cybertronic space.
