The Transformers Adventure Easy Dynamic Series release, titled "Big Optimus Prime", features extra paint details and has two additional Autobot symbols on his shoulders. He also includes a different scannable badge, which is compatible with TakaraTomy's Transformers Adventures app. Scanning this will unlock Big Optimus Prime in the collection list. Unlike the American release, Big Optimus Prime is packaged in a windowed box, instead of an an open package.
At BotCon 2005, Hideaki Yoke revealed that Optimus Prime (or more accurately, Diaclone Battle Convoy) was not designed by a single person, but rather a team of Takara designers as the one who was originally assigned the job had fallen behind. It is said that a young Shoji Kawamori was also a member of this team at some point, who would design THS-02 Convoy over 20 years later. The patent for the toy, however, lists Hiroyuki Obara as the designer.
Early versions of this storyline featured Rodimus returning as "Rodimus Primal," a techno-organic Maximal with a form similar to Optimal Optimus'. This concept was discarded in favor of Rodimus working alongside Primal Prime, but was later adapted for a storyline feature in "Ask Vector Prime." In an alternate reality where Starscream had possessed Waspinator and brought a premature end to the Beast Wars, Rodimus Primal led the Wreckers as one of several resistance group's to Megatron's rule over Cybertron. Eventually, Megatron was overthrown by his rebellious generals Obsidian and Tankor, splintering the Vehicon force prior to the pair being abducted by Unicron. Without Obsidian's leadership, the Vehicons crumbled, and Rodimus Primal became part of a new Cybertronian ruling council that also included "Waspscream," Magmatron, and Mutant leader Icebird.
Throughout the first two seasons, Optimus Prime has led the Autobots to many victories, such as stopping Megatron from controlling the crystal of power, stopping the Dinobots' rebellion by saving Grimlock, defeating Devastator with his detach arm, helping capture Nightbird, rescuing Blaster and Cosmos from the Decepticons on the Moon with the help of Omega Supreme, and helping save Perceptor and the other Transformers from the cosmic rust disease.

QT-M Optimus Prime is a redeco of the GT-R Optimus Prime mold in the colors of the Transformers-sponsored Nissan GT-R used by the Team Mach racing team (a vehicle previously used as the base for non-toy character Mach Five Racing Prime). Like Transformers GT's Safety Prime, this toy was a collaboration with the Super GT racing series and was given away free to young children who attended TakaraTomy-sponsored "Kids Walk" events held by Super GT in the fall season of 2015.
The series begins when Optimus and his crew, after picking up a disillusioned ninja named Prowl, are sent to clear rubble from a space bridge passage. There, the Autobots stumbled upon the Allspark and are immediately attacked by Megatron's battle cruiser, the Nemesis. Through treachery by Megatron's second-in-command, Starscream, Megatron was fragged and the Autobots crashed on Earth in the early 21st century. After being in stasis under Lake Erie for 50 years, the Autobots awaken in Detroit of the near future, where they immediately discovered humans in need and became heroes of the city after stopping a Sumdac Industries experiment gone wrong. During the battle for the possession of the Allspark, Optimus goes offline after defeating Starscream, only to be revived by Sari Sumdac and her Allspark-infused key.

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.
