Optimus suffers from a design flaw that many other Voyager Class figures in the Combiner Wars line experience: the detents, or "click points", on the heavily-ratcheted outward motion of his hips (which also form the hips of his torso mode) are few in number and very far apart. As a result, Prime's legs have great difficulty assuming the natural "A-stance" formation that the angled design of his foot sculpt seems to have been meant to accommodate. Likewise, when forming the torso of Ultra Prime, the interactions of the knee-lock mechanism and the hip detents almost always force Ultra Prime's legs into either an awkwardly knock-kneed arrangement or an equally awkward, and often unstable, bow-legged posture (as seen in the image to the right) that prevents Ultra Prime from standing flat-footed. Unlike Motormaster, this version of Optimus was the only one to not receive the improved hip ratchets implemented in its future releases in some shape or form by Hasbro, though they would be used for the Battle Core redeco later in the line. However, there are third party ratchet replacements for the hips.
Optimus later led a convoy in search for a building site for Autobot City, which ran into a Decepticon ambush. Rodimus Prime remembers the Transformers greatest battle on Earth. He sent off several Autobots to get help, knowing this was the only chance of victory. Transformers Combat Data Those several Autobots were seen again, but Prime... wasn't.
The figure was re-released in Hasbro's Asian markets in 2012, with no known changes to the figure itself but several modifications to the packaging that makes it easy to tell the two releases apart: The flap containing the package art is omitted entirely, the "Commemorative Series II" label is missing, the age recommendation and safety warning labels, the "Changes from double tractor trailer to battle station to super robot!" call-out and the name of the toy have all been shuffled around (with the words "battle" and "super" being omitted in the process), and most notably, the toy is no longer named "Powermaster Optimus Prime with Apex Armor", but simply "Optimus Prime", with Apex Bomber's existence no longer acknowledged anywhere on the packaging.
Unfortunately for both Takara and Hasbro, the Generation Two series of Transformers sold poorly, and Hasbro abandoned it after two years. There were toys planned that never saw release. Most of these were G1 combiner team recolors or recolors of recent figures. Four unreleased molds were released in the Machine Wars line, and four more resurfaced in the Robots In Disguise series.
Late in 2008, this version of Optimus prime was one of four Classics figures repainted into HasbroToyShop.com exclusives (the other three being the Megatron from this set in G1 colors, Grimlock repainted into Overkill, and Mirage repainted into Dragstrip). Unlike those three, it's debatable just how much repainting went into Optimus, but he comes in a snazzy new box.
Released alongside a Sega Mega Drive version of Megatron and outside of any other toyline, "Optimus Prime featuring Original PlayStation" transforms from robot to a scaled-down non-functional Sony PlayStation video game console. He features an opening disc compartment and comes with two accessories, a memory card and a controller that splits in two and attaches to his lower arms to act as blasters.
Powermaster Prime's animation model as used in the commercials and as a character guide for the Marvel comics is a composite of the second and third designs. The body of the model is actually a straight tracing of the concept lineart for the third version (including its different rifles and twin faux shoulder stacks), with a slightly simplified drawing of the second version's head drawn on top.
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.
