Hot Rod then fought in the battle of Autobot City and saved the city for if he had not attacked Megatron, he would have destroyed it. Due to his attempted intervention in the epic battle between the Autobot leader, Optimus Prime and the Decepticon leader, Megatron, Prime was lethally injured. Before he died, the Matrix got passed on to the Autobot Ultra Magnus, whom he referred to as "old friend", despite protestations.
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.
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.
A redeco of the Dark of the Moon Deluxe Class toy, this Optimus Prime has large portions of his body, mostly his truck parts, vacuum metallized silver, and his light-piped eyes were neutered by blue paint. He comes with a redeco of Generation 1 Rampage's sword, which can be wield by his 5mm-compatible hands (Although not shown in the instructions). As his body, legs, and front truck kibble were chromed, care must be taken while transforming, especially with the shoulder kibble & the bottom leg's posts (This can be amended if you slightly widen the holes with 3mm hand drills). As with the original Dark of the Moon Deluxe Class figure, the instructions did not mention about forming the sleeper part until step 10, the pinky finger prevented the sword to peg down through his hands, and of course: his truck mode can attach with the Armored Weapons Platform included in the Chronicle or the Movie Trilogy Series figure. This figure has slightly loose shoulder joints.
He made it out of the building and ran into the real Sunstreaker, who blasted the 2 clones following Hot Rod. Sunstreaker ignored Hot Rod's warning about Scorponok's army and stormed into the building so Hot Rod painfully wired himself to send a distress signal. When Sunstreaker's real head was later disabled by Hunter, the Headmaster clones shut down, which Hot Rod explained to Grimlock. The group was surprised by the arrival of Shockwave, but Ultra Magnus had heard Hot Rod's distress call and was on his way to Earth. After Scorponok knocked out Sludge and Grimlock tended to him, the remaining Dynobots offered Hot Rod a lift aboard the Monsterbots' ship. He refused though, and made it back into Machination HQ to take care of something "personal". He eventually found Scorponok's real head. Hunter also showed up and let Hot Rod know how to disable it, but before he could do so, Scorponok grabbed him. Before Scorponok could crush Hot Rod's head, the Dynobots showed up and began to battle Scorponok. Hot Rod told Swoop which wires to sever, and he did just that, reducing Scorponok to a catatonic state. Ultra Magnus arrived took everyone back aboard his ship, which later docked with the Ark-32. Within 3 days, Hot Rod was fully repaired, with a new body form design.
This Optimus Prime is a new Voyager-sized Triple Changer mold, which transforms from robot to tanker truck to plane and back. His robot mode is heavily based on Generation 2 Laser Optimus Prime, whilst the deco appears to draw from Star Convoy. His Titan Master partner Diac transforms into his head (but any Titan Master figure is compatible). Like all Titans Return Voyager class figures, he has built in mechanisms to "bulk up" his noggin. In his case these are spring-loaded pylons. His robot mode also features fake truck windows.
An undocumented aspect of his transformation is that his gun, which splits in two halves and secrets inside his kibble when transforming (much like Rattrap's) has two handle pegs on opposite sides, so that it can be held either at its far end or halfway along its length. The former position makes the weapon look (charitably) more like his traditional ion blaster—or Ultra Magnus' rifle. Additionally, the gun halves can be plugged together in two different ways, theoretically allowing you to create an infinitely long weapon (or at least one of ridiculous proportions).
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.
