The TakaraTomy release of Optimus Prime has considerable differences from the Hasbro release. His blue and red plastics are darker and metallic, his translucent blue plastic is darker, and a few of his paint operations have been omitted and replaced with customer-applied foil stickers, such as his shins, feet, headlamps, and insignias. His legs, outer forearms and truck mode "sleeper cabin" side panels have been retooled to include 5mm post-holes as part of the line-wide "Arms Micron" gimmick. As such, he does not come with the Hasbro version's weapons, but instead an Arms Micron partner named O.P. who transforms into a weapon resembling Optimus's in-show blaster cannon. This version of the mold was also used to make Prime Nemesis Prime.
While stock photos and renders show the figure with a faceplate, this image posted by the Transformers Facebook page shows him with his mouth exposed. This was later found as a variant at least once. A running change was made, changing the blades to be more translucent. The semi-translucent blades release features a date code "73461", whereas the translucent orange blades version features a date code written as "80171".
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.

Available exclusively from Japanese 7-11 stores, MP-711 is an Ultra Magnus-decoed Convoy—white with green and blue highlighting—themed with 7-Eleven logos. Unlike most MP-10 redecos, he comes with a trailer, Roller, and Spike figure, who is sporting a 7-Eleven uniform. Roller and the combat deck come with 7-Eleven logos, however Convoy's shoulder logos are stickers with the option of a green 7-Eleven logo or the standard Autobot logo on either shoulder.
While they wandered through the tunnels, the Joes and Prime found cave paintings that described the last visit to Earth by the planet-eating god Unicron. They were attacked again by Bludgeon and Cobra-La minions, but were led away by a ragged Joe Colton, prisoner of Cobra-La for the last 25 years. Black Horizon, Part 1 of 2 Bludgeon managed to find them again and during a second battle Prime tore open the Pretender's shell, revealing Bludgeon's robot form inside. Bludgeon tripped and dangled dangerously over a chasm, but rather than let Optimus Prime save him, Bludgeon forced Prime to drop him to his death laughing all the way down.
Although the animated series ended in the U.S. after The Rebirth, Optimus Prime continued to appear in animated sequences of Transformers toy commercials, progressing from Powermaster to Action Master. He even made an appearance as a computer-generated Combat Hero. Many episodes of the series were re-aired to promote Transformers: Generation 2. During these sequences, computer-generated scenes featuring key G1 characters are borrowed from Generation 2 commercials to serve as opening, closing, and commercial bumpers. Optimus Prime is shown in the opening and closing fighting Generation 2's Ramjet.

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.
If Optimus ordered his troops to come to the humans’ aid, they found themselves taking part in a struggle in futility, as the entire town was near-weightless, meaning they couldn’t put the humans anywhere where they wouldn’t float away once more. Then, the Autobots heard Decepticons approaching. Helpless in their current position, the Autobots were quickly eradicated by the Decepticons.
