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.
Like many other modern toys, Optimus was designed with an alternate head sculpt (based on the mouthplate-less face as seen on the show) intended for a later retool, which was gang-molded with the original head. At least one specimen sporting the mouthplate-less head has been found at retail, although since this occurrence has seemingly been limited to an isolated incident, it can be assumed to be a manufacturing error rather than a genuine variant. The mouthplate-less head sculpt was eventually used officially for a later-wave redeco, Nightwatch Optimus Prime (see below).
Like the original figure, Powermaster Prime is composed of two major components: his truck cab, which transforms into Prime himself, and his trailer, which is essentially a heavily-armed version of the original. The trailer has a fold-down ramp to allow the storage of a smaller Transformer, or perhaps spare accessories. The trailer transforms into a battle station armed with two long black rifles and two grey double-barreled cannons (featuring seating for Powermaster engine figures), all of which Optimus Prime can also wield in his fists.
Released to commemorate the 10th anniversary of Revenge of the Fallen, this Studio Series Optimus Prime is a retool of the figure above, featuring many new parts, namely a new backpack, chest piece, and a pair of non-transforming fenders/legs, to better resemble his appearance in the first two movies. These new parts allow him to combine with Studio Series Jetfire to form "Jetwing Optimus Prime." His color scheme features a much higher contrast than the previous release. Instead of Energon Swords, he now comes with an ion blaster like that used in the battle of Mission City. He also comes with a cardboard backdrop display depicting the highway fight with Bonecrusher from the first Transformers film.
Although the original Japanese incarnation of Transformers: Cybertron, known as Transformers: Galaxy Force, was produced apart from Armada and Energon, the series, as originally conceived by Hasbro, was as the third part of the trilogy. The English language dub of the series treats it as such. Consequently, inconsistencies arise between Cybertron and the other two series, but have been explained by the Cybertron comic book, available exclusively through the Official Transformers Collectors Club, as the result of fluctuations in the fabric of reality caused by the Unicron-induced black hole.
It took two further years, but this figure was eventually released as part of the Japanese counterpart to the Alternators line (Binaltech) in 2008. Binaltech Convoy features some additional paint details, like his silver pelvis, additional patterns on his shoulders, and red paint on his engine-gun, and like all Binaltech figures, he also includes die-cast metal pieces. Unlike previous Binaltech releases, a bio-card was not included.
A redeco of Legends Optimus Prime replacing his red plastic with more blue and silver, but sprucing things up a bit with red flame paint operations. Defender Optimus Prime (ディフェンダーオプティマスプライム) was only available in Japan as part of their Transformers Animated promotion in March 2010. It was given away for free to customers who purchased Animated merchandise at Edion, Bic Camera and Yodobashi Camera stores.
This small version of Energon Optimus Prime was released by Kabaya as part of their DX Transformers line of candy toys. Prime transforms in the same manner as the larger Energon figures do, though his arms have to be removed at the shoulder and reinserted into his back to form truck mode. The Prime Force were sold in a separate set in the DX Transformers series, and can combine with Prime to form his Super Mode. Optimus came with a stick of gum.
Hot Rod's tech specs list him as an Autobot Cavalier, while as Rodimus Prime, he is listed as an "Autobot Protector" - unlike Optimus Prime's, which directly states "Autobot Commander". A commercial for the toy hinted at his ascension, but pitted him against Cyclonus and Scourge instead of Galvatron, who was his chief adversary in the animated series.
The lowest priced toys in the Armada line were three-packs of Mini-Cons. Each larger price point consisted of an Autobot or Decepticon who came with a Mini-Con partner. Mini-Cons could be used to unlock a variety of features on each larger robot, such as firing weapons, electronic lights and sounds, or alternate modes. Some three-pack Mini-Cons combined into other forms or had additional features. According to the storyline, Mini-Cons also enhanced the power of other Transformers, giving incentive to collect as many of them as possible.
