Near the end of the series, in what is generally regarded by fans to be his most impressive feat, Optimus Prime takes on Galvatron without combining with any other transformer. Traditionally, throughout the three series and RiD, Optimus Prime has been shown to be physically weaker than Galvatron. At the end of the intense fight, Galvatron proved stronger than Prime, but Prime managed to destroy Galvatron with Vector Prime's sword.
In "Mission Accomplished", Optimus is pressured by Sentinel to tell Ultra Magnus that his story about the Decepticons is untrue, but he refuses. Meanwhile, the on-board computer plots a train infused with a shard of the Allspark. When Ultra Magnus and Jazz set off there, Optimus suspects that the Decepticons are luring them into an ambush and rushes to their help, though Sentinel Prime tries to detain him. At first, Ultra Magnus doesn't believe him, but a short time later, Optimus is proven right as Starscream falls from the sky after being blasted by Megatron, much to Sentinel Prime's astonishment and fright. Starscream turns out to be alive, inflicting injury on Ultra Magnus. Optimus takes the affair into his own hands momentarily and, with Sentinel's aid, manages to apprehend the Decepticon. While Sentinel Prime deflects Starscream's shots with his power-shield, Optimus succeeds in taking Starscream by surprise and handcuffing him. When the shackled Starscream is delivered to the Elite Guard spaceship, Ultra Magnus admits Optimus Prime was right and allows him to stay on Earth in order to seek out the other fragments of the Allspark.
Part of the first wave of the 2015 Robots in Disguise line, Optimus Prime is a smaller-scale toy. He transforms from robot to trailer/truck combination and back! Like every Robots in Disguise Legion Class toy, Optimus features 3mm posts on his hands and arms. Due to the size and simplified transformation, he ends up having 6 wheels instead of 10. His scannable Autobot insignia is on his robot mode left shoulder. However, the badge is completely impossible to scan in vehicle mode.
The Universe incarnation of Generation One Optimus Prime is a redeco of the Robots in Disguise Scourge's Spychanger toy, a smaller, simplified version of the original mold. He replaces most of the black plastic with predominantly red and blue, with silver for detailing, with an overall deco making him resemble the original Optimus Prime. Like most Spychangers, he features high speed axles and can roll very well across smooth surfaces, but lacks the weight to propel him quickly.
The first Transformers toys were created from two different transforming robot toylines from Takara, the Car-Robots and Micro Change, from the Diaclone and Microman series, respectively. Hasbro acquired the rights to sell them in the United States but, instead of selling them under their original names, they were rebranded as "The Transformers". The first two years consisted primarily of reusing the Car-Robots/Micro Change molds. The earliest toys had some parts made of die-cast metal, which were eventually phased out.
The Transformers toyline was created from toy molds mostly produced by Japanese company Takara in the toylines Car-Robots (Diaclone) and Micro Change (Microman). Other toy molds from other companies such as Bandai were used as well. In 1984, Hasbro bought the distribution rights to the molds and rebranded them as the Transformers for distribution in North America. They approached Marvel Comics to create a backstory with names and short descriptions for each character, most of which were written by Bob Budiansky.
Power Surge Optimus Prime is a new mold, in the size of a Leader Class figure, which transforms in 7 steps. It comes with the Mini-Con Aerobolt, who transforms from a bird to his chestplate. This triggers electronic lights and sounds, as well as deploying a mask, two shoulder cannons, and a pair of large wings for the larger robot. His front truck kibble can be removed, but you can transform him into vehicle mode with the kibble on.
When the warlord Shokaract, powered by Unicron's Dark Essence, traveled into the past to secure his own future, the occupants of J'nwan decided to act. Optimus Prime, Megatron, Soundwave, and Grimlock joined Sandstorm on prehistoric Earth during the time of the Beast Wars where the battle with Shokaract had already begun. When the Covenant arrived to vanquish the Dark Essence and defeat Shokaract, Optimus Prime and the others escaped through portals as that timeline was erased from existence. Terminus Departure
For Transformers: Age of Extinction, Optimus Prime initially transforms into a rusty 1973 Marmon semi cab-over truck and later on a new alternate mode in a blue and red Western Star 5700 Custom semi-truck. After humanity turns on all Transformers, regardless of faction, Optimus and the other Autobots go into hiding. Eventually, they find themselves being hunted by a rogue organization called Cemetery Wind. Optimus is severely injured in a trap set by the group, while many of the other Autobots, including Ratchet and Leadfoot, are slain. An inventor, Cade Yeager, comes to Prime's aid and helps restore his health. After uniting with a small band of Autobots, Optimus faces Lockdown, a ruthless bounty hunter allied with the humans, and KSI, an organization that produces man-made Transformers. Optimus is captured by Lockdown, but the Autobots rescue him. Optimus is quickly losing faith in humanity, but at the urging of Cade, chooses to stay and fight a resurrected Megatron and his new army. Prime awakens the ancient Dinobots, and rides a newly tamed Grimlock into battle through Hong Kong. He kills Lockdown and Harold Attinger at the film's climax as revenge for killing many of his friends, including Ratchet and Leadfoot. At the end of the film, he leaves Earth and flies off into deep space, seeking to find out the truth about his mysterious Creators.
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.
