According to the bio printed in the Transformers Collectors Club magazine, Optimus Prime was a member of the Cybertron Dimensional Patrol, but was abducted by Unicron. It is unknown whether he repainted himself yellow before being abducted or if the recoloration was due to the radiation emanating from Unicron, which has a tendency to recolor Cybertronians.
Like the original Warrior Class Optimus Prime, the figure features an undocumented feature: His axe can be stored on his vehicle mode trailer. Additional features include storing the axe onto either of his leg hooks, combining the launcher with either of the swords at their hilt, and storing the launcher underneath the vehicle. In a neat bit of engineering, he can fully transform with his swords attached.
Optimus Prime is the leader of the main group of Autobots in the iteration of the Transformers franchise primarily marked by the 2010 computer animated series Transformers: Prime on The Hub. Optimus Prime was created as the last of the Thirteen Primes, the first generation of Transformers, each created directly by Primus as a band of unique warriors to combat and defeat Unicron. Upon his creation, Optimus united the Thirteen by his greeting All are one. While all of the other members of the Thirteen each possessed unique abilities and artifacts, Optimus wielded no special powers or weapons. It was only through his vision and courage that allowed the Thirteen to finally defeat Unicron. Reborn through the Well of All Sparks, Orion Pax became Optimus Prime, a veteran military commander and second in command who wields an ion blaster and a double bladed energon axe. He became the leader of the Autobots after Sentinel Zeta Prime fell in battle, but is not certain he wants the responsibility.
Released in the first wave of the Authentics toyline, "Autobot Optimus Prime" is a new mold the size of a 2015 Robots in Disguise Battle Pack toy. He changes from an evergreen-inspired robot into a more G1-based truck in just four steps. His instructions are incorrect; for truck mode, his legs must be folded in before the arms, otherwise the locking tabs on the arms will get in the way. Due to his transformation, he ends up with no elbows and a fake chest. He also has problems standing up due to hollow legs.
We know that despite starting his fictional life as a lovable, horn-headed robot who could turn into a Volkswagen in Generation 1, Bumblebee's most well-known these days as a round-headed robot who turns into a Camaro. In fact, younger viewers might not even realize he was ever anything but the Chevy muscle car. But there’s one quirky continuity where he’s able to switch between original and movie modes at will.
Optimus Prime has appeared in numerous video games since the introduction of the Transformers series. He makes a cameo in the 1999 Beast Wars Transmetals video game for Nintendo 64, where he is killed by Megatron at the end of the campaign, showing what would have happened in the Beast Wars series with a Predacon victory. Prime is also one of the playable characters in the 2003 Japan-only Transformers game for the PlayStation 2 and the 2010 Transformers: War for Cybertron. Optimus Prime is also playable in the Hasbro Net Jet Transformers fighting game Transformers Battle Universe. Three versions of Optimus Prime are playable characters, including the first generation incarnation, his incarnations from the 2007 live-action film, and the incarnation from Transformers Animated. In this game, Optimus Primal is also a playable character. He is a regular character in the Nintendo GameCube and PlayStation 2 2003 fighting game DreamMix TV World Fighters. He appeared as a boss in a simple Flash-based video game on the Hasbro web site.
Optimus Prime returns in Transformers: The Last Knight, which is set three years after the events of the previous film. Having been frozen in the vacuum of space, Optimus has been drifting on the far reaches of Earth's solar system for some time. However, he later crash-lands on Cybertron, its atmosphere reviving him. He then confronts the being currently in control of the planet, a powerful sorceress named Quintessa, who professes to be the maker he is searching for. Optimus is easily subdued by Quintessa, who convinces him that he destroyed Cybertron and reveals that the Earth is actually Cybertron's "ancient enemy" Unicron. Redubbing him "Nemesis Prime", Quintessa brain-washes Optimus and tasks him with retrieving her stolen staff, with which she plans to drain Earth/Unicron's life force so that Cybertron can be restored. Nemesis succeeds in retrieving the staff, but is hindered by Bumblebee, whom he engages in a fierce duel. Nemesis nearly kills Bumblebee, but when the normally mute Bumblebee suddenly speaks, urging Prime to remember who he is, the sound of his oldest friend's voice is enough for Optimus to return. However, Megatron, revealed to be in league with Quintessa, swoops in and steals the staff from Optimus. Prime is then attacked and sentenced to death by the Guardian Knights for aiding Quintessa, but he is saved by Cade Yeager, who convinces Optimus to correct his mistake. Optimus leads the Autobots in the attack on Quintessa's lair, during which he slays the Infernocons and defeats Megatron. Optimus then attacks Quintessa, distracting her long enough for Bumblebee to shoot and seemingly vaporize her. At the end of the film, Optimus and the other Autobots return to Cybertron, unaware that Quintessa is actually still alive.
With this reconstruction, Orion Pax became Optimus Prime, the first of the Autobot warriors. Optimus took the mantle of leadership as the civil war against the Decepticons erupted, and would remain in that position for the next nine million years. Ariel was rebuilt into Elita One, the commander of the Autobot resistance on Cybertron. The fate of Dion is left unrevealed. It has been speculated by fans that Dion might have become Ironhide or Ultra Magnus just as Orion and Ariel became Optimus and Elita, but this remains fan speculation only, and, his close friendship with Optimus notwithstanding, there is no evidence to support the idea.
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.
