Now in possession of the glasses which could tell him the location of the AllSpark, Optimus remorsefully left Bumblebee in Sector Seven's hands despite protestations from Jazz and Ironhide Prime was unwilling to employ the deadly force he knew would be required to teammate, as he knew humanity held the potential to be something great.Using the glasses to trace the AllSpark to the Hoover Dam, Prime led his men there, but while they were en route, the Decepticons who were also in hiding on the planet launched an attack on the facility. When the humans slipped, Bumblebee was forced to break cover to rescue them, which resulted in all three of them being captured by S7. Sector Seven back-up soon arrived, however, forcing Prime to hide beneath a bridge, carrying Sam and Mikaela on his shoulders. Prime intercepted the S7 convoy, tearing the roof off the SUV containing the two kids and demanding that the organization's director Seymour Simmons release them. Nevertheless, the Autobots managed to keep themselves hidden from Sam's parents long enough for Sam to find the glasses-at which point, the forces of Sector Seven arrived to take Sam and Mikaela into custody. Prime had his troops wait outside while Sam and Mikaela searched for the glasses, but the Autobot leader's thunderous footsteps, clumsy attempts to hide, and general impatience made the whole experience quite a trial. Meeting up with Bumblebee, Prime and his men were introduced to Sam Witwicky and Mikaela Banes, with whom Prime shared their history and their reason for being on Earth.Prime and the Autobots returned with Sam to his house, so that he could obtain for them a family heirloom: a pair of glasses belonging to his ancestor Archibald Witwicky, which contained the location of the AllSpark encoded across its lenses.


After descending through Earth's atmosphere in his transition form, Optimus scanned a passing truck, then quickly learned the planet's languages via the internet. In the year 2007, having received word from Bumblebee that the AllSpark was on the planet Earth, Optimus brought his troops to the small, blue world.
