A re-release of the Leader Class figure from the Revenge of the Fallen line, but with retractable forearm hooks (as seen in his battle with Grindor) in place of the blades. In addition, the figure comes with the unmasked head of Buster Optimus Prime and is painted with battle damage effects. A recording of Peter Cullen saying, "We must stop the Decepticons!" is played when his chest is pushed upward via a lever on his waist. Fans have nicknamed this figure "Battle Hooks Optimus Prime" to distinguish it from the other Prime figures.
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.
Legion Class Optimus Prime has been found at Family Dollar and Dollar General stores in the United States. A later variant repleaced the red Autobot insignia with a black version. This later version was also released at general retail in Australia, New Zealand, Europe, and Russia. In Singapore it was released together with Bumblebee and Starscream as part of the promotion for Age of Extinction in selected cinemas.
The project was crowd-funded through Japanese crowd-funding site Makuake. For 5,400 yen, contributors received an INFOBAR Optimus Prime, or for 16,200 yen, received INFOBAR Optimus Prime, INFOBAR Megatron and INFOBAR Bumblebee, the only way to obtain the last two items. The project received one million yen in the first 24 hours, ultimately topping out at over 32 million yen.
Four million years ago, Optimus Prime ended a Decepticon attack on the Ark by directing it towards prehistoric Earth. When both factions reawakened in 1984, Optimus Prime and the Autobots fought the Decepticons on numerous occasions until 2005. During an attack on Autobot City on Earth, Prime fell in battle against Megatron and passed the Matrix of Leadership to Ultra Magnus.
Rodimus gained the help of the criminal Witwicky family, believing they would help him learn more about Earth. After fighting Goldbug for leadership of the Autobots, he renamed himself Rodimus Prime. His first attack on the humans was to take control of the base controlling a human military satellite and use it to blackmail the humans into making him the leader of the world. The Decepticons were able to break into the base, where Heatwave used his ability to control machines to have the satellite fire on its own controls and then destroy itself.
In 2007, following the release of the Matrix's energy, Prime began to suffer from visions which foretold a great transformation for Cybertron. Events began with the Decepticons' theft of the key to the Plasma Energy Chamber, which forced Prime to consult Alpha Trion within Vector Sigma. Prime learned that the mega-computer had orchestrated events in order to restore Cybertron's Golden Age. When the Plasma Energy Chamber was opened and threatened to drive Earth's Sun supernova, Spike Witwicky and the Nebulans, who had become involved in the conflict as a result of these events, were able to drain off the excess solar energy and revitalize Cybertron. With the Decepticons driven off Cybertron and Nebulon free from tyranny, Cybertron enters into a Golden Age of peace and prosperity under the leadership of Optimus Prime and the Autobots.
Dark of the Moon Voyager Class Optimus Prime is an all-new mold. He features heatshield details in his sculpting and translucent solar panels on various parts of his body, and huge gas tanks. Optimus himself is differently proportioned, having larger feet and a smaller torso and arms. He also features some faux-kibble/parts: His actual windshield chest is being covered by a sculpted panel featuring his characteristic deformed windshield-chest, and a pair of sculpted tires on his thighs. His pair of optics is designed to have a light-piping gimmick, but it was rendered useless since it was painted in smoke gray on top of the colorless transparent plastic.
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.
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.
