He comes with a MechTech rifle converts into a large battle axe, and can be locked in by pulling the lever all the way in and tilting it into a gap to the left. The rifle has a separate flip-out handle, while the axe uses the rifle's long barrel as the handle, meaning that Optimus can grip the axe with both of his hands. This weapon was also retooled in a running change, adding a stop to the handle instead of relying solely on the gear system to prevent the locking assembly from flying off into parts unknown.
Apparently, early plans for the shield were to have it colored gold and silver, but it was later changed to gray and red. When a hand-painted prototype of the toy was first displayed at the 2013 New York Comic Con, the shield was colored yellow and silver; in addition, the original versions of the official Hasbro stock photos also depict the gold color, but the versions featured on the back of the toy's packaging were edited so they would accurately depict the final toy's colors for the shield. Meanwhile, the versions of the stock photos provided to websites and online retailers depict the shield in its final colors for the robot mode, whereas the vehicle mode photo is the unedited version featuring the shield's original colors. Furthermore, UK-based retailer Argos also featured unedited versions of the stock photos for both modes in one of its catalogs, causing some confusion among fans. Sometimes, the spring loaded "Automorph" feature in his head is too strong and causes the head to fly off...
Hero Optimus Prime was the first new-mold Optimus Prime toy in the Generation 2 line. He transforms into a Kenworth truck of unknown model with a flatbed trailer. The truck and trailer form his robot mode, but cannot disconnect. His primary gimmick is an air-powered missile launcher that uses an air bellows attached by hose to launch his large, hollow, soft-rubber-tipped missiles. The bellows and missiles attach to his back in robot mode. His rifle plugs into the launcher's main body in truck mode.
An all-new Leader class figure of Optimus Prime, featuring a robot design and transformation that is closer to its film counterpart than the 2007 toy version. Features retractable blades on both forearms. New "MechAlive" feature consists of visible moving gears in the chest behind the cab windows. At the push of a button on the back of the cab, the truck mode emits an engine idling sound. The transformation sound is played when the upper torso and lower torso are connected. A recording of Peter Cullen saying, "I am Optimus Prime!" is played when his chest is pushed upward via a lever on his waist.
Available only via mail-order through Dengeki Hobby magazine, this black and gray redeco of Optimus is one of four "Black Body" promotional Robot Masters toys made available through different outlets simultaneously. He came with his normal accessories (it is worth noting his axe was solid silver), plus a chromed-gold clear-red-plastic version of Psycho-Orb's "Calamity Defenser" solitarium shield.
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. 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.
This Japanese exclusive release of Optimus Prime features much more black coloring than the previous releases, and it's (coincidentally) based on the Fast Action Battlers Power Armor Optimus Prime toy, so as to be used with the similarly-repainted Legends Jetfire figure to form the Optimus' powered up combination. For some reason, he has red eyes. This redeco also uses the slightly small fuel tank/elbow tabs from the Battle Damaged release.
The "robot mode" of Optimus Prime is where the pullback motor and working wheels of the toys lie. Optimus is sculpted in blue plastic, pre-posed in an odd crouching pose with zero points of articulation. His right knee is bent back, with his right arm touching his knee, while the left side has the leg forward and the left hand holding onto his butt. The toy is as sparsely painted as the truck, with light blue eyes and chest windows, gray hands and feet among other parts, and red forearms. Two panels on his back have red flame tongues on them.
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.
In the alternate universe of the 2003–2004 toyline and series, Transformers: Energon, Rodimus (lacking the "Prime" suffix in English, but still called Rodimus Convoy in Japan) was a great leader on Cybertron ages in the past and was viewed as a hero by many, including similar character Hot Shot. Desiring to escape the war that had consumed the planet, Rodimus departed Cybertron with a contingent of like-minded troops, most of whom settled on an alien planetoid and became the energon-mining Omnicons. Still, Rodimus continued on his journey with Prowl and Landmine, carrying the "flag of peace" from world to world.
The TakaraTomy "Autobot Alliance" release of this toy has some significant differences, including casting the red plastic in a darker shade, making his shin and wheel joints grey rather than Hasbro's bronze, painting the Matrix of Leadership silver, and swapping out the dual energon swords for battle hooks, similar to 2010's Leader class Optimus Prime. However, due to the Japanese release retaining the Hasbro packaging, the box still advertises the dual energon swords rather than the hooks. He retains the masked face used for the Hasbro release.
