The sequel series, Transformers: Robots in Disguise sees Optimus contacting Bumblebee to warn him of danger on Earth-a prison ship's complement of Decepticon prisoners escaping upon the ship crashing and appearing briefly in physical form to help Bumblebee's unlikely new team defeat the Decepticon Underbite. Optimus appears throughout the first season as a vision to Bumblebee, though he is only allowed to do so when the latter's need is dire. Residing in the "Realm of the Primes", Optimus Prime begins training to combat an "ultimate evil" where his first part of the training is overseen by Micronus Prime. At the conclusion of the first season, Optimus is upgraded by the Thirteen Primes when the Fallen arrives on Earth, during which he gains a body that closely resembles his Beast Hunters form. After the Fallen is seemingly destroyed, Optimus Prime remains with Bumblebee's group, though he states he would only do so as Bumblebee's "equal", rather than leader. However, the Thirteen subsequently reclaim the additional power they granted him, leaving him weakened but still determined to aid the team.

"Convoy Last Production" was the final re-use of the Masterpiece toy mold before it was at last retired after numerous re-releases and redecos. The figure is essentially identical to the original Japanese MP-1 release, aside from a slightly brighter red, and the addition of the words "LAST SHOT" in Transformers typeface molded into the small of Convoy's back, hidden beneath its headlight-flaps in robot mode. Lacking the trailer of MP-4, the figure instead comes with a redecoed version of the electronic base included with Hasbro's "DVD Edition" of the figure from five years prior, which now features a collection of sixteen soundbytes of Convoy delivering famous lines from the Japanese version of the Generation 1 cartoon, recited by the character's original Japanese voice actor Tesshō Genda. The base was promoted as containing a hint as to the identity of the next Masterpiece toy; as it would turn out, this was a new version of Convoy himself (see below), foreshadowed by a sound clip on the base which played only intermittently, and which had Convoy announce that he would "soon be reborn".
After a period of effective leadership, which saw the activation of several new Transformers including the Aerialbots, who Prime infused with life using the Matrix, Prime engaged Megatron in a video game duel for possession of a super fuel. Prime was victorious, but Megatron implemented a cheat code that killed Prime later. Autobot surgeon Ratchet's subsequent efforts to restore him were unsuccessful, and his body was launched into space. The Autobots were unaware of the presence of the physical Matrix within the corpse. The funeral barge eventually crashed on a giant moon and, as it lay there for an untold time, the Matrix reached out to nearby living organisms, studying and recreating them.

This new smaller mold of Optimus Prime features a similar transformation to the original toy. Unlike most transformable figures in this line, Optimus completely lacks 5mm fist holes. Compared to the finalized toy, the product photo on the back of the box has a number of deco differences, most notably silver thighs and white accents above the front windows in addition to those below. The same box photo and the more deco-accurate stock photo (right) also neglect to fold out his fists, which is the only other step in his two-step transformation.


Part of the sixth wave of the 2010 Transformers toyline, this Optimus Prime is an all-new Deluxe class mold based on the original Generation 2 Laser Optimus Prime toy (see above). Transforming into a racing truck, he has some influences from the live-action movie Optimus Prime, including the more defined flames on his hood, athletic robot mode proportions and a more aggressive-looking translucent orange sword that can be held with both hands for maximum extreme chopitude. Optimus Prime features extensive use of translucent plastic in his arms, head and upper torso for a light-piping effect. Optimus also has a (non-detachable) matrix gimmick in robot mode that is formed by a relief pattern on the inside of the cab's side windows and is visible through the windshield/chest in robot mode. Like the Legends toy, he's part of "Reveal the Shield" and features a rubsign, this time on the roof. He is also very articulated and poseable, even featuring ankles and wrists that are both ball-jointed and hinged.

The Autobots and the Decepticons came to a distant world in the grip of an ice age. Assuming alternate modes based upon the dominant (though doomed) indigenous creatures of this planet, they continued their ancient, unending war. However, the Autobots, with their energy levels dangerously low, withdrew from combat as the world grew colder. They sought refuge in a deep cavern and entered stasis lock, awaiting the day when surface conditions changed to better suit their operation. Hearts of Steel #1 Optimus lay under the Mare Rurek Glacier. Infestation 2: The Transformers #1 Millions of years later, Bumblebee was awoken by the hammering of humans working on a rail line. He briefly considered awakening Optimus Prime, but thought better of it. After discovering the world had changed significantly, Ratchet thought there was no reason to awaken Prime. Hearts of Steel #1 When Bumblebee discovered the Decepticons were once again active on this world, Ratchet and Prowl agreed that the Autobots must intervene, but again decided out of rousing Optimus from his slumber. Hearts of Steel #2


The Transformers Energon figure pen is based on Optimus Prime in his standard Energon body. About the size of a scout class toy, he transforms from truck mode to robot mode almost identically to his mainline toys, apart from the fact that his feet contain the pen and cannot bend. It's really hard to write with, and almost impossible to pose, even though it has full arm articulation. Amusingly, this figure can position itself to transform into his super robot mode (by flipping his helmet on, opening his chest and flipping his hands in), but because there are no versions of the Prime Force drones in this scale, it's impossible to complete him.
Based on his appearance in War for Cybertron, Generations Optimus Prime transforms from a red, blue, and silver robot into an "armored truck mode." He comes with a hand-held rifle that is held via either of its two 5mm posts, and can fold up to store in either mode. He features additional 5mm ports on his forearms, roof, and front-wheel panels. Optimus has a stylized sculpted Autobot insignia on his back, as seen in the game, but it is obscured by kibble.
Another game was released for the Sony PlayStation 2 by Atari; simply titled as Transformers, it was based on The Transformers: Armada. The game's reception was mixed, particularly due to the popularity of a PS2 Transformers game released at the same time for a Japanese-exclusive market, though the Armada game was of a higher quality and featured much better gameplay. The game not released in America was based on the Generation 1 storylines.
If Optimus ordered his troops to come to the humans’ aid, they found themselves taking part in a struggle in futility, as the entire town was near-weightless, meaning they couldn’t put the humans anywhere where they wouldn’t float away once more. Then, the Autobots heard Decepticons approaching. Helpless in their current position, the Autobots were quickly eradicated by the Decepticons.
