The U.S. release of Super Fire Convoy had the Japanese voice replaced with an English voice (with the lines, "Optimus Prime, Maximize!" and "Autobots, Transform"), and Autobot insignias were added on the side panels. Much like the Japanese version, Optimus Prime's normal robot mode can combine with Ultra Magnus (sold separately) to form Omega Prime.
This agenda led the Predacon Megatron to attack the comatose Optimus Prime in stasis on prehistoric Earth, forcing Primal to take Prime's Spark into his body in order to preserve his life while his body underwent repairs. Primal was subsequently mutated into the massive "Optimal Optimus" form, which shared elements of Prime's form, prior to returning the Spark to its rightful place. The Maximals were occupied throughout the remainder of the series protecting Prime and the other Transformers aboard the crashed Ark until the Predacons were defeated. Various monuments to Optimus Prime appeared on Cybertron in Beast Machines, one of them a holographic statue in Iacon that Megatron took control of in order to trick Primal.
Part of the second wave of Warrior class figures, this Deluxe-sized Optimus Prime transforms into a futuristic trailer truck. Due to his simple transformation scheme, he has a faux window chest in robot mode, while the end of the front trailer kibble has extra toes. Optimus Prime also comes with an axe, which was based on the Energon Axe weapon from the War for Cybertron game. Undocumented in the instructions, Prime's axe can store between his trailer, or plug into ports on either of his shoulders. His scannable Autobot insignia is on his robot mode left shoulder and is easily scannable while still in-package.
During a Decepticon attack, Cliffjumper pleaded with Optimus to let him jump into the fray. Optimus denied his request, telling him that they already had the Decepticons on the run. In the battle’s aftermath, the Decepticon’s activity seem to vanish altogether. Grateful for the quiet, Optimus decided to head out and fetch extra fuel for the Autobots with Sparkplug. He returned just in time to find his Autobots in the middle of a battle with the Decepticons. With Sparkplug and Prowl’s help, Optimus refuelled his troops, and once more drove the Decepticons back. Revenge of the Decepticons
With the data from the piece price evaluations I was able to also evaluate the average size of LEGO sets each year. As you can see on the chart below, the average size of sets released each year stayed somewhat constant from 1980-1990 until around 2000 which set sizes started to increase. The average set size seems to have peaked in 2008 (which saw the release of the Taj Mahal), but since then it hasn’t fallen to its pre-2000 levels. It seems to have found a new normal around 300 pieces.
Leaving his home universe, the Optimus Prime of Primax 895.0 Gamma was gathered in Axiom Nexus by its Optimus Prime, along with a roster of other Optimus Primes and their kin in a group known as the Convoy, in which he was redubbed "Hero Prime". Optimus Prime bio in Club magazine #49 A multiversal cataclysm in a universe seeded with Rarified Energon and an invasion by natives from the negative polarity universe had called them into action. Since Matrix bearers were usually never allowed into Axiom Nexus, this was a grave threat indeed! Invasion Prologue
The second Nightwatch Optimus Prime was released as part of the "AllSpark Power" second half of the Movie line. He is similar to the UK version of Nightwatch Prime, replacing most of his red and blue with different shades of blue and black, retaining his resemblance to Diaclone Powered Convoy in most respects. However, the subdued black and copper on the first Nightwatch Prime have been replaced with gold and a very bright blue, to signify the All Spark energy affecting the Transformers. The translucent parts were also cast in purple translucent plastic instead of black translucent plastic.
Partially constructed of die-cast metal, this small three inch figurine of Optimus Prime has a CGI-accurate sculpt compared to the larger toys, owing to the fact it does not need to transform at all. He is sculpted with his Ion Blaster in his right fist, and is articulated at the neck, shoulders and waist. He comes with a small movie-style Autobot sigil display stand.
Labeled as a "Triple Changer", Striker Optimus is a redeco and retool of Dark of the Moon Supreme Class Jetwing Optimus Prime, with new weapons. The base figure has most of the same mold changes as Jetwing Optimus Prime (see below), but has been altered further; in particular, the transforming smokestacks and fuel tanks/ion blaster parts have been replaced with retooled regular tanks that now function as mounts for the new accessories. The colors on the toy are darker than Jetwing Optimus, with a different flame deco that extends farther along the sides of the toy. Additionally, two new 5mm holes have been added to the gray hinge behind the cab in order to accommodate the Toys R Us Japan-exclusive battle blade accessories. The "I am Optimus Prime" saying of Buster Optimus Prime has also been replaced with the "We must stop the Decepticons!" saying of 2010 Transformers Optimus Prime, although batteries are not included.
A repaint of the Armada Supercon Optimus Prime, minus the Mini-Con, but instead had a Cyber Key with a Mini-Con port in it. Repainted to match Cybertron Galaxy Force Optimus Prime. This is supposed to be a drone which Optimus Prime controls to get into small places, built for him by Metroplex. Several paint variations of this toy exist, and early releases have the forearms swapped, just as had occurred with the last repaints of the mold.
In robot mode, like Combat Hero Prime, the bottom of the truck became his familiar windowed chest based upon the original Optimus Prime toy. His main gimmick was light up LED headlights, and a lightpipe in the bottom of his right fist, illuminated by an LED in his right forearm, that would illuminate his clear sword or his double-barreled rifle if they were used in that hand. All three LEDs were activated simultaneously by pressing the sunroof-like depression on the roof of the truck.
