The instruction manual for the MP-04S Convoy Sleep Version reveals a hidden message saying that Rodimus will be the next installment in the Masterpiece series. Concept sketches of the figure were released online in July 2010. The figure is a faithful modern recreation of the original G1 toy. Gimmicks include retractable binoculars, spinning saw blade and the Matrix of Leadership, but the figure's main feature is the ability to transform into both Hot Rod and Rodimus Prime. The transition between the two incarnations involves rotating the face, extending the legs and adjusting the spoiler on the back.
Alternators Optimus Prime transforms into an accurate 1:24 scale Dodge Ram SRT-10. The vehicle mode features rubber tires, functional steering, opening hood, tail gate and doors with a detailed cabin interior. Several of the details of his robot mode body are based on the sculpt of the 20th Anniversary Optimus Prime figure, but the head itself shares more similarities with the Powermaster mold. He is armed with a small pistol which transforms into his vehicle mode engine.
Later, the Transformers were all transported to Cybertron by Primus to battle Unicron. Although Unicron had tainted the Matrix after killing Thunderwing, Prime managed to reacquire and purify the Matrix. Prime then sacrificed his life one more time to destroy Unicron by plunging the Matrix into his maw. The Powermaster process, however, had been working to fully bond Prime and Hi-Q. Prime's death completed the process, and the two minds and souls became one. Hi-Q's biomechanical body was stripped down and reconstructed by the Last Autobot, resurrecting Optimus Prime once more with the two minds now one. Prime rejoined the other Transformers on the planet Klo and routed Bludgeon's Decepticons.
Unlike previous Convoy toys, the cab section did not separate from the trailer, instead forming the arms of his imposing 12-inch tall robot mode. He lacks any sort of leg articulation in this mode, but his battery powered treads can provide him with locomotion. Star Convoy's chest can open to reveal a control center for Micromaster figures such as his partner figure Hot Rodimus to ride in.
In Transformers: Alliance, Optimus Prime and the Autobots aid the human soldiers after the battle in Mission City and destroy the Allspark-powered machines that were created. A trailer is obtained for Optimus Prime to carry the remains of Jazz. The Autobots leave Mission City as the Sector 7 personnel arrive to claim the remains of the Decepticons. About a month later, Epps and Lennox contact Optimus Prime about aiding them in escorting the remains of the Decepticons to the naval yard. They are spied on by Barricade, who transmitts the information to Starscream.
Optimus Prime's Japanese name is "Convoy", which is named after his original name "Battle Convoy" in the Diaclone toyline, because the name "Optimus Prime" is difficult for Japanese kids to remember and pronounce. All Optimus-inspired characters were called variations of Convoy in Japan up until the 2007 Transformers film, at which point TakaraTomy changed their minds and began using the name Optimus Prime as well. Presumably to avoid confusion, this change includes the Generation 1 version of the character as well, who is now called Optimus Prime in newer products and fiction such as Transformers United and Transformers: All Spark, though his name remains Convoy in material aimed at adult collectors such as Alternity and Masterpiece.
Optimus appears again in the 2011 film Transformers: Dark of the Moon. Optimus receives his own armory consisting of weapons and flight tech that transforms into a trailer for him to carry in vehicular form. After assisting NEST operatives in fighting Shockwave at Chernobyl, Optimus learns that the humans have concealed the discovery of a Cybertronian ship on the moon. He and Ratchet go to investigate the Ark, where they recover Sentinel Prime, Optimus's predecessor and mentor. Optimus returns him to life using the Matrix of Leadership back on Earth, explaining how they lost the war and Cybertron has become a barren wasteland. Later Optimus shows Sentinel the natural beauty of Earth, and takes the opportunity to offer him the Matrix, but was allowed to keep it. Sentinel later betrayed the Autobots, having formed an alliance with the Decepticons because he wants to restore life to Cybertron. Optimus attempted to reason with Sentinel, but failed as several Decepticons came through a space bridge. After Sentinel Prime insisted that the humans expel the Autobots from Earth, the Wreckers prepare the Autobot ship Xantium for flight. Sam attempts to find out what their counter-attack plan is, but Optimus states they have none, and that Earth's fight is their own. During the departure, the Autobots escape in the first booster stage and return to Earth before Starscream destroys the ship. Arriving in Chicago, Optimus shoots down a Decepticon fighter as he tells Sam and Epps that he never expected the Decepticons to keep their word and that they are going to fight back. Optimus loses his trailer when Shockwave and his Driller arrive. He manages to retrieve it later and uses it as a flight pack, decaptitating the Driller's main head. During the battle, Optimus got caught in exposed wires and the Wreckers helped free him. Flying down onto the main battlefield, he abandoned his flight pack and used the momentum to attack and kill many Decepticons before he finally killed Shockwave. After using Shockwave's cannon to disable the control pillar for the space bridge, Optimus fights Sentinel Prime. Optimus Prime's right arm is cut off and Sentinel is about to end Optimus's life when Megatron intervenes and attacks Sentinel. After defeating Sentinel Prime, Megatron proposes a truce, but, instead, Optimus slices his head off, killing the Decepticon leader. Optimus Prime then grabs Megatron's shotgun and prepares to execute Sentinel, who pleads for his life, saying that he betrayed Optimus just because he wanted to save their race. Optimus executes him anyway, replying that Sentinel betrayed himself. With the Decepticons defeated and the war finally over, Optimus and the Autobots accept Earth as their true home.
The designs for the original 28 figures were made by Kojin Ono, Takashi Matsuda, Hideaki Yoke, Hiroyuki Obara, and Satoshi Koizumi. Hasbro would go on to buy the entire toy line from Takara, giving them sole ownership of the Transformers toy-line, branding rights, and copyrights, while in exchange, Takara was given the rights to produce the toys and the rights to distribute them in the Japanese market.
In "Sick Mind", Optimus is infected with the life-threatening Cybonic plague, prompting Arcee and Bumblebee to infiltrate the Nemesis to find a cure for the virus Megatron himself created. As Optimus grows weaker, he learns of Megatron's survival of the space bridge explosion. It was Bumblebee entering Megatron's mind via cortical psychic patch and retrieving the cure that saved Optimus. In the next episode, "Out of His Head", Optimus is, surprisingly, saved by the revived Megatron when he intercepted Starscream's attempted nosedive to kill him.
If Perceptor gave out the right amount of an antidote, the poisoned Autobots were cured. Optimus ordered his troops to ready themselves for the incoming squadron of Decepticons. Perceptor’s antidote did have a side-effect on the Autobots, however; it gave them a fierce battle-fever, making them eager to take on the Decepticons head-on. Prowl suggested to Optimus that they instead opt for a more conniving counterstrike against the Decepticons, and ambush them instead.
The official international Transformers convention is BotCon, but other fan events include Auto Assembly and TransForce in the UK and past Transformers only events have included BotCon Japan, BotCon Europe and "OTFCC". The first larger Transformers convention in the Nordic countries is called "The NTFA Mini-Con", with official support from Hasbro Nordic, and was held by members of the NTFA - The Nordic TransFans Association, for the first time on November 3–4, 2007. The second NTFA convention with official support from Hasbro Nordic, now renamed "NordCon" (to avoid copyright problems with the name "Mini-Con") was held in Aalborg, Denmark from 19 June to 20 June 2010. It featured Simon Furman as a guest of honour. In 2011, NordCon and Auto Assembly joined forces to create a new convention called Auto Assembly Europe, which first took place in Uppsala, Sweden, in November 2011.
Originally, Optimus Prime was created as the leader of the Autobots, though it is unknown how he was created or his origins. In a possible future, Megatron was threatened by the existence of the Aerialbots and had Shockwave build a time machine to send them back in time to get rid of them. However, he only ended up changing history for the better. In the revised timeline, Optimus Prime began his life as a robot named Orion Pax, a mostly defenseless dock worker during the Golden Age of Cybertron nine million years ago, with a girlfriend named Ariel and a best friend named Dion. During this time, a new breed of robot with new flight capabilities appeared on the planet that Orion idolized. When Megatron, the leader of the new group of robots, approached him with inquiries about using one of the dock warehouses, Orion was swayed by Megatron. Both Orion and Ariel were severely wounded when Megatron and his forces attacked in order to claim the energy stored there. Searching for someone to help them, the time-displaced Aerialbots took Orion and Ariel to the ancient Autobot, Alpha Trion, who used them as the first subjects for the new reconstruction process he had developed involving rebuilding the frail Autobot frames into more battle-hardy configurations.
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.
Ultra Magnus's legendary status was exceeded only by the legendary status of Optimus Prime. Combiner Wars Ultra Magnus toy bio Upgraded with the power of combination, Optimus could combine with any bots to form Ultra Prime. Combiner Wars Optimus Prime toy bio With mastery over the power of Combiners, the combined courage of Optimus and the Autobots would stop the Decepticon Combiners threatening cities and entire civilizations.

The second known version  ditched the triplechanging gimmick on the cab and simplified things a good bit. This Powermaster Prime has several distinct characteristics only seen in the second design, such as the wider "block head" and two faux smokestacks on top of either shoulder as opposed to one. Also, in a rather odd twist, this design features a black head and fists for both super and regular modes rather than the traditional blue. It also had yellow eyes in either mode a la the original Optimus Prime.
Compared to the Combiner Wars release of the mold, Convoy features additional paint operations on the thighs, truck bumpers, the details on the inner legs, the gestalt chest halves (which are now painted over due to being molded in grey plastic), and the gestalt torso's lower section. The stomach's deco is also minimized, and the silver paint operations on the lower legs are now replaced with gunmetal while the mute metallic blue is now shiny metallic. When it comes to unpaintable plastic; his leg joints and feet are now blue, while the gestalt skirt flap is now the same grey as the arms. In addition, his flip-up gestalt leg panels and thighs are now molded in black, with the latter being painted in silver with some yellow details.
The instructions neglect to mention that the entire roof of the cab is on a concealed hinge which greatly eases the difficulty of Prime's transformation. For whatever reason, the instructions treat the toy as if the hinge does not exist, going so far as to show Prime's head magically clipping through his chest to transform. The instructions also neglect to mention that his heel/bumper pieces must be slid out until they click, making the figure just that bit more stable, and that the rotating truck door panels on his upper arms can be pulled further out (but not off) from their sockets, allowing more space for the panels to swing around his hood-arms during transformation.
Available exclusively from Japanese clothing company A Bathing Ape in March 2013, "Convoy Reissue BAPE VERSION RED CAMO" (コンボイ復刻版 BAPE® VERSION RED CAMO) is a redeco of the original Optimus Prime toy sporting a unique new red color scheme, along with a red trailer decorated with a camouflage pattern. Both trailer and Prime himself feature the A Bathing Ape logo in place of an Autobot symbol, while the floor of the trailer's Combat Deck mode features new Bathing Ape-themed labels. The figure comes in a recolored version of the original Japanese packaging.
In Transformers Ongoing, which takes place two years after the events of All Hail Megatron, the Autobots would remain on Earth as Prime feared the return of the Decepticons. Unfortunately, this led to the capture of a number of Autobots by Skywatch, including Windcharger, Gears and Prowl. Hot Rod was reformatted into a Pagani Zonda. Already frustrated, he lashed out at Optimus, accusing him of keeping the Autobots on the planet because he needed someone to protect and demanding he be allowed lead a team to rescue Prowl. An admonished Prime agreed to a covert operation, but with Ironhide along to watch over things. While Prowl was freed, it turned out the humans had used him as bait to draw the other Autobots in. However Wheeljack's new shielding protected Hot Rod's team from Skywatch's inhibitors and in a panic the soldiers switched to lethal measures. Hot Rod was targeted and Ironhide was killed protecting him. An enraged Hot Rod turned on the humans, damaging their equipment and machinery.
