Unlike the other Swordbot toys, Optimus Exprime's kabuto helmets form an integral part of one of his alternate modes. The kabuto helmet designed for use with his DaiGekisou combination forms the head of his dragon form, while the kabuto helmet designed for use with his DaiKenzan combination forms the "tail" of the same. He comes with two HUGE swords (with 5mm handles) which can be attached to several places on his kabuto helmets or either alternate form, held separately in his hands, or held both in the same hand (with one held in reverse-grip).
This Wal*Mart-exclusive two-pack pairs the deluxe-size Classics Optimus Prime figure with live-action movie line's Fast Action Battlers Power Hook Optimus Prime toy. Both toys are identical to their original releases, and together represent the Optimus Primes of the oldest and newest generations (at the time) of Transformers, respectively. The movie Prime is designated "2007 Optimus Prime", while the Classics figure is dubbed "1984 Optimus Prime" (referring not, of course, to the toy, which was produced in 2006, but to the character).
Naturally, Optimus Prime got the biggest of the sets in the first year of Kre-O. The set can be built into a large long-nose tractor-trailer rig with a removable "sleeper" cab that hides a computer station, and a trailer that can carry the set's two motorcycles or open up to carry larger car builds. The robot mode build includes a huge Optimus, based largely on the live-action movie Optimus, though with a head based almost directly on the Classics Voyager Optimus. He is armed with a distressingly plain brick that fires pressure-launched missiles (aka his smokestacks). Most of the leftover parts in robot mode become a "headquarters" which is mostly just a random assemblage of mismatched-color panels and a pair of barricades. Both main builds leave numerous parts unused if you go expressly by the instructions, but hey, it's a building kit, surely you can find someplace to apply most of them.
Released in the latter stages of the Cybertron toyline, this redeco of the Leader-class Optimus Prime figure introduced a new colour scheme that several other tail-end releases would emulate. Taking its name from the Japanese version of Cybertron and with a bio noting that this new body depicts Prime after he embarks on his galaxy-spanning mission at the end of the Cybertron cartoon, "Galaxy Force" Optimus Prime replaces the original toy's blue parts with black and the translucent blue with smokey clear, and moulds several—but not all—grey parts out of red plastic, including the toy's rifles, rail gun covers, missile launchers, and Super Mode leg guns. In the realm of new paint operations, Prime now sports all four Cyber Planet Key symbols on his shoulders, and his unique Matrix-shaped Cyber Key (now with the code lo9x) finally has a gold-painted border, as it had always had in Japan. Additionally, Prime's hip joints were tightened up with this release, making it easier to stand him up in Super Mode.
Part of the fifth wave of 2012-onwards Generations Deluxe Class toys, Thrilling 30 Orion Pax is a new mold with a robot mode inspired by Guido Guidi's design for the character, originally seen in Spotlight: Blurr. Some liberties have been taken with the original concept to facilitate his truck mode, which is a new design not based on the Guidi art. He comes with his Ion Blaster and an Energon Axe with a transparent red-orange blade, both of which can peg onto 5mm ports on his hands and vehicle rear sides. Although not depicted on the instructions, the Ion Blaster can also peg into the hole in the larger blade of the Energon Axe.
Optimus Prime is armed with two large rifles formed out of a combination of both smokestacks and fuel tanks. These rifles peg into lower arms with grips for his open hands. The under-slung fuel tanks can fire spring-loaded projectiles. In vehicle mode, both smokestack rifles can be deployed as twin cannons, and this mechanism can also be used to store the rifles and deploy them as shoulder guns in robot mode.
Part of the first wave of TakaraTomy Lost Age: Movie Advanced toys, this Japanese-exclusive redeco of 2007 Transformers Protoform Optimus Prime is given a Generation 1-styled color scheme (which is also based on his appearances in IDW's Transformers: Foundation comic-book mini-series). Protoform Optimus Prime transforms into his "entry" mode. This mode somewhat resembles a cybertronic truck, with false wheels sculpted onto the sides, and Optimus Prime's trademark windows in front. His now-blue flame decoration piece fits to the back of the "vehicle", creating the illusion of a flaming comet's tail (Not sure if this was mean to represent his jetpack blast effect or his atmospheric entry heat effect, which is for no reason: entirely blue instead of hot red). The bottom of the vehicle has small wheels to roll the toy across smooth surfaces.
