Many of the small features and electronics of the original Masterpiece mold are left out. Instead, this Convoy features better overall cartoon accuracy (chest interior, head, etc.), an extensive red paint job that covers much of his red plastic, corrected robot mode proportions, improved articulation, and its gun can now collapse and store inside a compartment on its back in either mode. In addition to Convoy's trailer, which can transform into Combat Deck, it also comes with Roller, a small Spike Witwicky figurine, a die-cast metal Matrix of Leadership (with a clear blue plastic center), and an energy axe that slips over Convoy's right hand. Spike can fit inside the cab in vehicle mode, ride in Roller's seat, or fit into any of the seating compartments inside Convoy's trailer. Roller has options to plug in Convoy's gun or pull Convoy's trailer, and the trailer itself can store Convoy's weapons in any mode. Although not easily breakable, care must be taken for posing the index fingers; extending the finger even far would cause it to pop off.
Armor Knight Optimus Prime is a retool of Age of Extinction: Generations Leader Class Optimus Prime. It features a new head sculpt with a rotatable faceplate (one side with the mask, the other without, the whole part rotates), along with other remolded body parts (such as his skirt, feet, and chest), giving it a more screen accurate appearance. He includes more movie-accurate weapons, featuring a new sword and shield, albeit in not-so-accurate colors (the sword's transparent orange blade was also a nod to the sword's "heat up" mode in the concept art.). He is covered in metallic paint, along with additional chrome details on his rims and bumper.
MP-10 Convoy, advertised as a "perfect new model" on its packaging, is an entirely new tooling of Generation 1 Optimus Prime. Convoy is now smaller, making him more in-scale with other recent Masterpiece toys, such as Rodimus, and comes with a trailer and various accessories. While the front of the vehicle mode's cab is an accurate depiction of a mid-to-late-1980s Freightliner FLT cabover, the back half, (which is, as usual, made out of Convoy's legs) is much larger and robot-leggier in proportion. (So much that they sculpt a ladder on each side.)
In his first appearance in the series, Optimus looks similar to the original G1 Optimus Prime until he copies himself with a semi-truck and his design in robot mode changes. Soon after, he retrieves his Mini-Con partner, Sparkplug Witwicky. The cab of his truck mode detaches to form Optimus himself, while the trailer transforms into a battle station mode operable by Optimus and several Mini-Cons. Optimus can also combine with his base to form a "Super Mode" robot that, when combined with Sparkplug, can fire a series of powerful lasers. Additionally, Optimus can combine with Jetfire and/or Overload in his Super Mode for additional power.
Originally, Optimus Prime was created as the leader of the Autobots, though it is unknown how he was created or his origins. In a possible future, Megatron was threatened by the existence of the Aerialbots and had Shockwave build a time machine to send them back in time to get rid of them. However, he only ended up changing history for the better. In the revised timeline, Optimus Prime began his life as a robot named Orion Pax, a mostly defenseless dock worker during the Golden Age of Cybertron nine million years ago, with a girlfriend named Ariel and a best friend named Dion. During this time, a new breed of robot with new flight capabilities appeared on the planet that Orion idolized. When Megatron, the leader of the new group of robots, approached him with inquiries about using one of the dock warehouses, Orion was swayed by Megatron. Both Orion and Ariel were severely wounded when Megatron and his forces attacked in order to claim the energy stored there. Searching for someone to help them, the time-displaced Aerialbots took Orion and Ariel to the ancient Autobot, Alpha Trion, who used them as the first subjects for the new reconstruction process he had developed involving rebuilding the frail Autobot frames into more battle-hardy configurations.
