Early in this new series of encounters with Megatron, Red Alert contacted the Autobots on Earth and asked for Optimus Prime to join then on Velocitron. Ransack and Crumplezone tricked Hot Shot and Dirt Boss into believing that a race between them would determine which of them would be allowed to race Override for the Planet Cup. During the race, Ransack and Crumplezone caused a rockslide that buried Hot Shot. Hot Shot was saved when Optimus Prime, Vector Prime, and Landmine arrived, but Optimus was upset that Hot Shot had become involved with the locals. Clocker and Brakedown were eager to help the Autobots. After being unable to obtain the Planet Cup from Override herself, Optimus Prime endorsed Hot Shot's plan to win the cup in a race with the aide of the other Autobots. Ransack and Crumplezone were contacted by Megatron and were told to keep on eye on things. They also decided to enter the race, either to win the cup and cause as much damage as they could to the other racers. Override, Dirt Boss, Ransack, Crumplezone, Optimus Prime, Hot Shot, Red Alert, Landmine, Clocker and Brakedown participated in the qualification round. In the final episode of Transformers: Cybertron, Optimus Prime proposed a new Space Bridge project using the power of the four Cyber Planet Keys and the four great Cybertronian ships. Many Autobots and former Decepticons joined in the project. Jetfire was left in charge of Cybertron as Optimus Prime led the Atlantis with the Earth Cyber Planet Key, joined by Red Alert, Safeguard, Scattorshot, Leobreaker, Menasor, and Heavy Load.

Optimus Prime is then informed that Megatron has infected the core of Cybertron with dark energon and is given the task to undo the damage done. After rescuing Omega Supreme, Optimus, Ironhide, and Prowl fight their way to the core, but it's too late. The core informs Optimus that it is far too corrupted. It can repair itself by shuting down, but it will take millions of years. By that time, Cybertron will have to become cold, barren, and uninhabitable. The core gives Optimus a small piece of itself, saying it will still survive as long as the piece does. Optimus accepts the burden and the core relinquishes the Autobot Matrix of Leadership.

In this incarnation, Optimus Prime is the main protagonist and shows a near-xenophobic reluctance with interacting with other cultures, believing that such interaction would cause more harm than good. Consequently, he prohibits his team from mingling with the locals of Earth, Velocitron, and the Jungle Planet during their search for the Cyber Planet Keys. This attitude was drastically changed when Prime realized that the only way to acquire the Cyber Planet Keys from Velocitron and Animatros was to play by their laws.


Four million years ago, Cybertron, shaken from its orbit and drifting through space, became threatened when it floated into the path of an asteroid field. Prime led a group of elite Autobot warriors on the Ark, the Autobot starship, on a mission to destroy the asteroids. Although the mission was successful, during the aftermath of this mission, the Ark was attacked by Decepticons hoping to overpower their weakened foes. Intent on keeping the secrets of the Ark from the Decepticons, Prime set the craft on a suicide course, crashing it into the then prehistoric planet Earth.

Kabaya's second candy toy of Energon Optimus Prime was released as part of the Hyper Transformers series. This non-transforming figurine depicts Prime in his lesser-seen combined mode with Wing Saber: "Fight Mode", as Hasbro called it, or "Cannon Mode" in Japan. The figure's shoulder cannons came on a separate sprue in-package and had to be removed by the buyer. Prime's head can be removed and attached to the Hyper Transformers Omega Supreme figure, creating Optimus Supreme. As a candy toy, Prime came with a stick of gum.
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.
Not depicted in the instructions or stock photos, Roller can attach to Prime in vehicle mode via two tabs on the vehicle front which slot into two corresponding slots on Prime's feet. Another undocumented feature is that the butt of the Ion Blaster can be inserted between the barrels of Roller's weapon mode to form a longer weapon. Also not shown in the instructions but depicted on the stock photo on the card-back is that Prime's shoulderpads can be rotated up; the intended positioning for this is notched, although you can position them at other angles.
Each arm features flip-out blades that trigger when a button on the forearm is pressed. Each of these blades has a Cyberglyphic symbol on it. The blades severely restrict Prime's arm articulation when retracted, as they get in the way of the kibble, but as there is very little one can do with Prime's arms without causing the blades to deploy, this is hardly noticeable.

The 2010 Transformers "Reveal the Shield" Legends Class Optimus Prime sculpt in the deco from the first Chronicle EZ Collection wave (see below) was released as a "Dollar Store" exclusive (available at stores such as Dollar General and Big Lots) in generic 2010 Transformers packaging packaging alongside Starscream, Bumblebee and Megatron. The initial release saw the copyright year removed, while a later running change variant featured the new tooling originally used for Generations Legends Class Motorbreath, with not only the retooled hands and a hole on the back of his head/top of his vehicle mode compatible with 3mm posts, but also Motorbreath's sword accessory.
Armada Built to Rule Optimus Prime transforms into a fair approximation of his vehicle mode, but the robot mode is quite inaccurate, due to the very broad, flat Trans-Skeleton with thin, stick-like limbs attached to it. The set came with a very simplistic "Mini-Con" Sparkplug partner kit that did have a more dedicated "Powerlinx" connector than the standard construction pegs, though these are a bit too thin to be used as attachment points for regular Mini-Cons (they stay, sort of, but it's a very loose connection). The 101-piece set also features pressure-launch missile-firing "smokestack" cannons.

Optimus took the mantle of leadership as the civil war against the Decepticons erupted, and would remain in that position for the next nine million years. Ariel was rebuilt into Elita One, the commander of the Autobot resistance on Cybertron. The fate of Dion is left unrevealed. It has been speculated by fans that Dion might have become Ironhide or Ultra Magnus just as Orion and Ariel became Optimus and Elita, but this remains fan speculation only, and, his close friendship with Optimus notwithstanding, there is no evidence to support the idea.
Available exclusively from Japanese clothing company A Bathing Ape in April 2012, "Convoy Reissue BAPE Ver. BLACK" (コンボイ復刻版 BAPE® Ver. BLACK) is a redeco of the original Optimus Prime toy sporting a unique new grey color scheme, along with a grey trailer decorated with a camouflage pattern. Both trailer and Prime himself feature the A Bathing Ape logo in place of an Autobot symbol, while the floor of the trailer's Combat Deck mode features new Bathing Ape-themed labels. The figure comes in a recolored version of the original Japanese packaging.
This Optimus Prime is a minor redeco of the One-Step Changer figure, omitting the paint apps on the knees, the flames on his shoulders, and changing the robot mode chest's deco. Along with his wavemate Bumblebee, Optimus Prime loses his pin on his leg, which is used to activate Stomp & Chomp Grimlock's pop-out weapons and gimmicks. As with the first wave of the Turbo Changers, Optimus features a nearly invisible tampograph on his vehicle front, which can be revealed with Mega Turbo Changer Dragonstorm's UV-powered Cyberfire gimmick.
The Jetwing jet pack attaches onto Optimus Prime via a part that hooks onto one of the hinges behind his neck, and a spring-loaded clamp that latches onto a recessed area under Optimus' back. The fuel tanks that form Optimus' Ion Blaster must be removed for this mode, and they can be stored inside the engines for the jet pack. The Jetwing can be used on previous Leader Optimus Primes from Revenge of the Fallen onwards, but due to the lack modifications seen in Jetwing Optimus Prime, the combination isn't as stable. The jet pack features four MechTech ports on the main wing articulation points, and two C joint mounting points on each wing. The Gatling Cannons both feature two MechTech ports and 2 C joint mounts on either side of each cannon.
The figure was re-released in Hasbro's Asian markets in 2012, with no known changes to the figure itself but several modifications to the packaging that makes it easy to tell the two releases apart: The flap containing the package art is omitted entirely, the "Commemorative Series II" label is missing, the age recommendation and safety warning labels, the "Changes from double tractor trailer to battle station to super robot!" call-out and the name of the toy have all been shuffled around (with the words "battle" and "super" being omitted in the process), and most notably, the toy is no longer named "Powermaster Optimus Prime with Apex Armor", but simply "Optimus Prime", with Apex Bomber's existence no longer acknowledged anywhere on the packaging.
