Part of the first wave of Prime: Robots in Disguise Weaponizer Class toys, Optimus Prime is a large toy, similar in size to Leader Class figures from previous Transformers toylines. He features a simpler transformation and design compared to previous Leader-sized figures, with him having fake chest windows (again) and a simplified, hollow truck rear where his feet, arms, and fake chest windows are plainly visible. He comes with a blaster which can mount onto his hands, shoulder-pads, and the sides of his legs/truck rear.
Created with the specific purpose of producing an Optimus Prime as accurate to the original animated series as possible, the toy is exceptionally poseable, partially constructed from die-cast metal, features rubber tires and vacuum-metalized plastic and is heavily detailed, with sliding pistons in its joints and working spring-loaded suspension in vehicle mode. The figure also contains multiple non-intrusive gimmicks, such as a moving mouthplate to emulate Prime's traditional method of speech, flip-up communications panels on the forearms depicting images of Bumblebee and Starscream, and an opening, light-up Matrix chamber in the chest, which contains a removable vacuum-metalized Matrix of Leadership that can also be pulled open.
In search of new energy sources, Optimus led a team to central South America. When they spotted Mount Sheelah, their two human friends John and Tim Gordon explained volcanoes, and, believing it to be of possible use, the Autobots went to examine it. During a battle with the Decepticons over the volcano, Optimus was convinced by the two humans to retreat, ultimately saving them when Mount Sheelah erupted. Terror of Mount Sheelah After discovering that the Decepticons were kidnapping humans, Optimus sent Bumblebee to scout the Decepticon base. When Bumblebee returned with the Decepticons' global crystal, Optimus was able to use it to blackmail the Decepticons into letting the humans go. Bumblebee to the Rescue
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.
