Accessories: Two Energon Swords, "Forest Fight" backdrop (1st version)
Studio Series Optimus Prime transforms from a robot into a Peterbilt 379 semi-truck. He comes with a pair of Energon Swords, which can be mounted onto his arms or store on the back of his robot mode or truck mode. The figure combines engineering concepts from his Age of Extinction Voyager Class figure with techniques previously used on Prime: First EditionOptimus Prime. He also features a more subdued color scheme compared to other Optimus Prime figures. Like the rest of the Studio Series figures, the figure prioritizes robot mode scale and thus stands shorter than his Voyager Class wavemate Starscream. The CG renders depict him possessing long smokestacks, but the final product has them shortened... again. He also comes with a cardboard backdrop display depicting the forest battle from Revenge of the Fallen.
While the 5mm compatible arms can fit with most weapons with the same post size, some of the weapons' handles can barely fit on it due to either the slightly thickened tab or sculpted thin panels.
The rear truck cabin/back kibble can turn slightly floppy over time in robot mode, as there are no tabs and holes to secure it. Despite being labeled as the Revenge of the Fallen version of the character, this mold is not meant to combine with the later released Jetfire, although it can be achieved with some fiddling. However, it can carry (but not combine with) Studio Series 44 Optimus Prime's trailer.
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".
TakaraTomy's stock photo of the robot mode is mistransformed on the right elbow: His forearm is bent backwards instead of forwards.
