Based on the Classics toy line, the Timelines 2007 story is set 15 years after the end of the Marvel Comics story (ignoring all events of the Marvel UK and Generation 2 comics). According to exclusive bio information in the Transformers Collectors' Club magazine #15, Hot Rod followed Optimus Prime back to Cybertron from the Planet Klo. Once back, Hot Rod took up racing, but after a while found it pointless. Optimus Prime assigned to help organize the millions of Cybertronian refugees who returned to their home world. Hot Rod chaired the Cybertron Grand Challenge race, a race which featyred combined Autobot/Decepticon teams. With his maturing Hot Rod changed his name to Rodimus and was chosen to return with Optimus Prime to Earth to stop Megatron. Optimus Prime returned to Earth commanding Bumblebee, Cliffjumper, Grimlock, Jetfire, Mirage and Rodimus. When the Cybertronians Skyfall and Landquake arrive on Earth unexpectedly, Megatron attempts to destroy them, but Optimus Prime and his Autobots are able to drive Megatron away. Rodimus is wounded on a mission with Optimus Prime, before being brought back to the Autobot base.
Prime's trailer opens up into his Combat Deck, containing the scout drone, Roller. The interior of the Combat Deck features three pegs that can accommodate Prime's laser rifle, fuel pump and nozzle accessories, and seating for two Diaclone drivers. As its central feature, the Combat Deck features a missile-armed repair drone pod mounted upon a boom lift arm (featuring another cockpit for a Diaclone driver), which can also be extended through holes in the trailer's roof and front-end when it is closed. Situated in the base of the boom arm is a spring-loaded launcher that can launch Roller out of the Combat Deck and into action. Roller himself has seating for four Diaclone passengers, and features a port that can accommodate either Prime's rifle or the fuel pump. The interior space of the trailer allows storage room for one standard Autobot car, which can also be shot forward by the launcher.
Surprisingly, this was also the first Hasbro exclusive transforming Movie Optimus Prime figure to be based on the final design seen in Age of Extinction. He even features the forearms that Prime had before obtaining the Sword of Judgement, which unfortunately means that he is inaccurate to his appearance in the battle of Hong Kong and the entirety of The Last Knight. The sword's blade is still painted as the heated-up version from the concept art.
Hasbro's Toys R Us-exclusive 2003 reissue of Powermaster Optimus Prime was actually a modified version of Takara's then-recently reissued God Ginrai set. As such, the cab was partly constructed out of die-cast metal, vacuum-metalized plastic and had clear blue windows. The trailer was retooled so the super robot's fists could slide in and out of the arms. This set also included the originally Japanese-exclusive Apex Bomber drone trailer that attached onto the back of Optimus Prime's trailer in vehicle mode, and could become extra armour in super robot mode.The missiles where unchromed and lengthened due to safety issues as opposed to the Japanese release which were chromed and shorter.
This retool of Revenge of the Fallen Leader-Class Optimus Prime features the head from Buster Optimus Prime and has had his blades replaced with semi-articulated Battle Hooks for face-destroying action! He has a darker paint job and sports black splotches on his body and head to signify battle damage. However, due to these extra "battle damage" paint applications, some other paint applications that were present on the Revenge of the Fallen release were omitted. He also sports a new voice box in robot mode, replacing the infamous "I am Optimus Prime!" with "We must stop the Decepticons!" The international release, however, retains the same abbreviated "Optimus Prime" sound clip as the original release. To the annoyance of many fans, this version was the main version released just about anywhere outside the United States (all of Canada, Latin America, Europe, and Asia). The box also mentions racing sounds, which may or may not be referring to the button-activated diesel engine noises carried over from the Revenge of the Fallen version of the figure.
An undocumented aspect of his transformation is that his gun, which splits in two halves and secrets inside his kibble when transforming (much like Rattrap's) has two handle pegs on opposite sides, so that it can be held either at its far end or halfway along its length. The former position makes the weapon look (charitably) more like his traditional ion blaster—or Ultra Magnus' rifle. Additionally, the gun halves can be plugged together in two different ways, theoretically allowing you to create an infinitely long weapon (or at least one of ridiculous proportions).
Legion Class Optimus Prime is a redeco/retool of the first Revenge of the Fallen Legends Class figure, with the deco resembling the paint job from Optimus Prime's Western Star "5700 OP" concept truck. While the main body is identical to the figure, the arms and legs are newly tooled, with simple assemblies for the wheels. The retooled legs now features a more solid stopping point, which prevents the center front grill/legs to swing back further. It should be noted that his flame decals are painted over the side windows.
Part of the first wave of Siege Voyager Class figures, Optimus Prime transforms from robot to short-smokestacked Cybertronian armored truck and back. He includes two weapons compatible with the C.O.M.B.A.T. System—the "W-50 Dual-Mech Energon Strikeshield", which is an axe that transforms into a shield, and the "W-M3 RF Ion Blaster". Both weapons can combine to form the "Sentrystrike Ultra-Blaster". Optimus Prime also features "battle damage" paint applications on several parts of his body, as well as multiple hardpoints all over himself and his weapons to accommodate "Fire Blasts" from the Battle Masters assortment, which can be used to simulate blaster fire or explosions.
A special edition Bearbrick released in celebration of the Transformers 30th anniversary, Optimus Prime is a redeco of Bearbrick G1 Optimus Prime in a deco based on his Age of Extinction appearance. He transforms from a Bearbrick painted up like himself to a bear-eared robot and comes with no accessories, but holes in his robot mode hands can accommodate other toys' weapons.
The Autobots subsequently returned to Cybertron aboard a refueled and repaired Ark with the defeated Decepticons, taking the Decepticons on Cybertron unawares and quickly capturing control Cybertron. Peace reigned for a time until a series of natural disasters began, the source of which was determined to be the planet Moebius in a parallel universe. The Autobots assembled a team to travel to this alternate universe and stop the threat; Optimus Prime personally led the team, unwilling to put anyone in more danger than himself. Wheeljack, Hoist, Jazz, Prowl, and Silverstreak constituted the rest of the team; they dubbed themselves Spy Changers because they aimed to achieve their goal with stealth and diplomacy. The team modified their bodies to match the native cyborgs using data acquired from the Sky Spy and traveled to the 22nd Strata but were soon attacked by the local Guardians, who mistakenly presumed them to be Renegades. The Spy Changers were then rescued by the real Renegades, who presumed them to be potential allies and took them back to their flagship, the Rogue Star. Renegade leader Cy-Kill attempted to court the Spy Changers as allies, but Optimus saw through Cy-Kill's deception. Eventually, the Autobots formed a secret alliance with the Guardians as well as discovered the cause of Cybertron's troubles: Renegade bases on Moebius were draining the planet's energy. The planet's geometry had turned it into a crude Dimensional Interfacer, and Moebius was tapping into Cybertron to sustain itself. Hoist was able to end the crisis by triggering the bases' remote detonation sequence. Cy-Kill was furious, but in the ensuing battle, the Autobot-Guardian alliance triumphed over the Renegades. Optimus Prime and Leader-1 shook hands as a symbol of the transdimensional friendship, and the Autobots returned to their home reality, secure in the knowledge that they had allies in places as distant as alternate realities.
