In a break from tradition, Energon Optimus Prime's large mode resembled a configuration similar to Voltron or to the Super Sentai action figures. This design was unpopular with many fans due to design issues with the toy. The small robot's body was large in proportion to his arms and legs which made the figure appear fat, earning it the nickname "Fatimus Prime" or "Obese-imus Prime". The 4 vehicles that combined with the robot were small, lacking the intricate detail that made other toys in the line popular. Fans were also angered by early releases of this toy in which the head was molded with a mouth rather than the traditional face plate design. Later releases of the toy eliminated the visible mouth feature.
A gold-chromed version of the Voyager Optimus Prime toy was available as part of the same Lucky Draw contest as the Golden Protoform Optimus (see above) in the December 2007 issue of TV Magazine. Limited to only 3 pieces, it is insanely rare. The photographed sample here features a chromed truck grill, while a boxed unit has an unchromed grey grill; the owners of both pieces, the Mapes Brothers of Transformers @ The Moon, believe both are genuine TakaraTomy toys, so it unsure if the one with the chromed grill is a testshot or a production variant.
Legends class Optimus Prime is an extremely simplified toy of the extremely complex movie design. As such, he features numerous unavoidable inaccuracies, such as not transforming or even looking very much like the original design or the larger toy versions in robot mode. However, proportionally Legends class Optimus Prime is not far off from the real truck and the Leader class toy's vehicle mode, aside from missing a smokestack on the driver's side. He is articulated at the shoulders and upper legs via ball joints. He can also hold small weapons, such as Cyberverse.
Optimus Prime is primarily voiced by Peter Cullen in most of his incarnations, who voiced him in the original series. Following the production of the 2007 film, Cullen reprised his role for the sequels and supporting media and would even voice Optimus in later series such as Transformers: Prime. Optimus has been voiced by a number of other voice actors in other series such as Neil Kaplan, Garry Chalk, and David Kaye in the series Transformers: Robots in Disguise, Unicron Trilogy, and Transformers Animated, respectively.
Sold at the rather exorbitant price of $75, this re-release of the original Generation 1 Optimus Prime toy is actually one of the most visually different from the other "straight" reissues of the mold, despite Hasbro's assurance that this is the toy you had as a kid. Positively anemic in comparison with the original toy, this Prime's red parts are visibly paler than usual, while his blue parts are much lighter (although the version released at Canadian retail reportedly sports a deeper shade of red again). This shade of blue extends to both Roller (a lighter blue than his traditional dark shade, yet darker than the lightest the figure has been in its history) and the internal workings of his Combat Deck, which is itself a much flatter shade of light grey, compared to its normal dark, swirled metallic silver color. In addition, the toy features the now-customary shortened smokestacks, and the elongated missiles seen on the Commemorative Series release. While all reissues of the Prime mold since 2003 have used the original thick-barreled mold for his ion blaster, this version includes the slender sculpt instead.
Jetwing Optimus Prime is a retool of Revenge of the Fallen Leader class Buster Optimus Prime, with an accompanying large jet pack and massive dual Gatling Cannons. The base Optimus Prime figure has several modifications including: a new stomach area and elbow flares to reflect the changes to Optimus Prime's CG model in Dark of the Moon, modified lower arms to incorporate MechTech ports and clips for the cannons, and a retooled area under his back so the jet pack can fit on more securely. The dual energon blades mounted on his arms have been removed. The toy retains Buster Optimus Prime's electronics, but batteries are not included.
This gold vacuum metallized (save for his black joints, which they were made out of unpaintable plastic) Protoform Optimus Prime figure was featured as a Lucky Draw giveaway (along side similarly gold vac-metal versions of Voyager class Optimus Prime and Protoform Starscream) in the December 2007 issue of TV Magazine. Released in 2008, only 5 pieces were made, making it one of the rarest Lucky Draw figures; the images at right represent the only known photographs of it.
