The Japanese release of the figure also underwent the changes in weapon shapes, but never featured a silver Roller; instead, their original release of Prime featured a Diaclone-style Roller without the two rear pegs, and the differently-shaped launcher that accommodated him, before a running change switched over to the Hasbro version of the mold. Finally, in some European countries, Prime sported red feet, as opposed to his traditional blue; this version of the figure is also known in some cases to feature a differently-painted forehead crest which leaves the three central indentations unpainted blue.
At some point, Optimus Prime disappeared under mysterious circumstances, and Ultra Magnus arrived from Cybertron to take his place as Autobot commander. Galvatron's Air Attack Prime eventually returned many centuries later, now sporting a Powermaster body, and rejoined the Transformers' war after it had moved from Earth to the alien planet of Nebulos.
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.
