While hiding under a bridge, Mikaela and Sam slipped and fell off Prime's shoulder. With a Sector Seven backup team en route, Prime ordered the Autobots to scatter, while he took Sam and Mikaela. The agents' lack of surprise at their appearance indicated that they had seen Cybertronians before, but Simmons refused to reveal any information. Optimus then ordered his comrades to relieve the agents of their weapons and attempted to interrogate Simmons. Prime intercepted the vehicle carrying their young human friends, ripping the roof of the vehicle off, with the other Autobots disarming the agents, and made it perfectly clear to Simmons how enraged he was at him for trying to apprehend the two children, regarding this as a bad move on Simmons' behalf. Optimus Prime sent the Autobots in pursuit of the SUV that contained Sam, Mikaela, and Sector Seven's director, Agent Simmons. Despite all this, their presence remained undetected until Sector Seven arrived and abducted Sam, Mikaela and Sam's parents. Ironhide suggested that he should kill the parents as they were very irritating, but Optimus scolded his old friend. When the parents came to investigate, Prime's attempt to avoid discovery caused the house to shake, as Ron jumps into an old cast-iron tub and stated that he hates earthquakes though this was to their benefit, as the father assumed that the damage to the yard was the result of an earthquake. Ultimately, Sam came so close to a panic attack that Prime was forced to order the Autobots to fall back. Prime's attempts to hide, such as having the Autobots transform into vehicle mode right in the backyard were also less than satisfactory. Much to Sam's exasperation, Optimus Prime, in his impatience, clumsily ruined his parents' garden.

Optimus arrived at Sam's house and waited outside while Sam and Mikaela searched inside for the glasses. After scanning a Peterbilt semi-truck as his alt mode, Optimus met up with Bumblebee, Ratchet, Jazz, and Ironhide in an alley and explained their history to Sam and Mikaela, as well as Sam's importance.


Without the AllSpark, Cybertron was reduced to a barren wasteland, forcing Optimus, the Autobots, and the Decepticons to abandon their homeworld and flee across space.įollowing a beacon sent by Bumblebee the previous night, Optimus, Jazz, Ironhide, and Ratchet arrived on Earth in their protoform modes. Near the end of the war, after the Ark, along with Sentinel Prime and the Autobots' last hope of winning the war, vanished into space, Optimus was forced to launch the AllSpark into deep space to keep it out of the hands of the Decepticons. When Megatron was corrupted by The Fallen and formed the Decepticons, Optimus rose up against him in a vicious war. Optimus mentored by Sentinel Prime, the last Prime before him, and eventually became the leader of the Cybertronian scientific division, while Megatron became Lord High Protector of Cybertron.
