Animated Optimus Prime, in an Earth-based fire truck mode, appears as a hidden character in the Transformers Netjet video game by Hasbro. Instead of being leader of the Autobots, Prime was actually a washout from the Elite Guard. Despite no longer being a member, he maintains his military ranking of "Prime". The scale chart released for the series indicates Optimus Prime stands about 22 feet tall.
If Cosmos radioed his findings to Optimus immediately, Optimus’s convoy moved in to investigate a nearby Decepticon base. En route, the Autobots passed near a human town, but began floating in mid-air before being able to reach it. Optimus quickly deduced that this phenomenon was caused by an anti-gravity beam, courtesy of the Decepticons. Worried about the nearby humans also being affected by the lapse in gravity, Optimus had to decide whether he would order his troops to stop and help the townspeople, or to continue forward and attack the Decepticon base.
Unite for the Universe Optimus Prime would have been a redeco of the 2007 Optimus Prime Voyager-Class mold in a similar style to the Leader-Class Buster Optimus Prime (see below), with a much more accurate and detailed paint scheme, including white stenciled flames. He would have come with a set of Jetfire armour parts to form the powered-up Optimus Prime seen at end of Revenge of the Fallen, and due to not having to form Jetfire's robot mode or his jet mode, the armour parts are far more accurate to the movie's design of them than the leader class Jetfire toy could manage. While not combined to Optimus Prime, the armour can be arranged to form a sort of weapon emplacement mode or a jet engine on the back of Optimus's vehicle mode.
While the other Autobots searched for the Matrix on Earth, Optimus Prime searched for Vector Sigma, guided through the dangers of the planet's catacombs by the spirit of Alpha Trion. Prime eventually arrived at the computer, only to find his way barred by Cyclonus and Scourge. At that moment, Hot Rod arrived with the Matrix, the same with which Alpha Trion merged, re-energizing it. The Matrix transformed Hot Rod back into Rodimus Prime and, for the first time, the two Primes fought side-by-side and defeated Galvatron. Before Rodimus could implement the Matrix to stabilize Vector Sigma, however, Optimus Prime merged himself with the computer, restoring its balance to save the planet. Optimus Prime sacrificed himself, dying again only a few short episodes after his rebirth. Later, Prime would make a final and permanent return in the Japanese Transformers continuity, Battlestars: Return of Convoy. This entry was only available in print, appearing in the TV Magazine, a Japanese publication.
As the Binaltech saga unfolds, the multiverse is threatened with destruction, until the original continuity is restored and the Binaltech universe is split into and preserved within its own separate universe. Overdrive confirms that the threat is over by visiting the dimension occupied by the original timeline, and reveals that in that world, Hot Rod had received the Matrix and taken over leadership of the Autobots as Rodimus Prime.
When Sideswipe was accused and convicted of destroying the Nova Suspension Bridge, Optimus was infuriated that one of his own Autobots could commit such a heinous act. Optimus was tasked to hunt down and deactivate Sideswipe, though the task proved to be easy as Sideswipe did not run, hide or resist. After Optimus had deactivated Sideswipe, he was approached by Prowl, who pointed out that Sideswipe's actions made little sense, as he had committed the crime in broad daylight before many witnesses. Agreeing that the Decepticons might be behind the situation, Optimus allowed Prowl to take a team of Autobots to Carob Island to clear Sideswipe's name while Optimus and Jazz stayed behind to continue working on human/Autobot relations. Prowl returned with evidence that it was indeed a Decepticon-controlled clone of Sideswipe that had committed the crime. Optimus then presumably reactivated Sideswipe when his name was cleared.
