Prime soon had other things to worry about, as Magnus arrived on Earth with the intention of taking the Matrix, which he believed was rightfully his, at all costs. Prime, who refused to fight back, was seriously injured by Magnus. Magnus tracked Optimus to a desert island, where he pretended to offer him the hand of friendship, only to attempt to absorb the Matrix for himself. During the struggle, the brothers combined into the form of Omega Prime, also known as the God Fire Convoy. Through this link, Magnus was also able to channel the power of the Matrix, which he used to supercharge the Autobot Brothers into newly colored forms. Prime went on to battle the Decepticons on many other occasions. Although Magnus remained a free agent, refusing to take orders from his brother, over time, his animosity dwindled, and he frequently helped the Autobots by combining with Prime to battle the Predacons and Decepticons. During the final battle with Megatron's new form, Galvatron, the two brothers finally reconciled. Together, they faced Galvatron at the Earth's core and defeated him once and for all.
This retool of Revenge of the Fallen Leader-Class Optimus Prime features the head from Buster Optimus Prime and has had his blades replaced with semi-articulated Battle Hooks for face-destroying action! He has a darker paint job and sports black splotches on his body and head to signify battle damage. However, due to these extra "battle damage" paint applications, some other paint applications that were present on the Revenge of the Fallen release were omitted. He also sports a new voice box in robot mode, replacing the infamous "I am Optimus Prime!" with "We must stop the Decepticons!" The international release, however, retains the same abbreviated "Optimus Prime" sound clip as the original release. To the annoyance of many fans, this version was the main version released just about anywhere outside the United States (all of Canada, Latin America, Europe, and Asia). The box also mentions racing sounds, which may or may not be referring to the button-activated diesel engine noises carried over from the Revenge of the Fallen version of the figure.
The first reissue of the original Optimus Prime toy in North America since the Generation 1 toyline reached its end, this "Commemorative Series" edition of the figure was a Toys R Us exclusive. It was mostly identical to the original figure, save for some necessary modifications made for safety reasons: In the first instance of what would become a recognizable alteration to the mold, the toy's smokestacks were shortened, while the Combat Deck's firing missiles were elongated to prevent potential choking, as was the case with all other Commemorative Series figures' firing missiles. This release also had the trailer's launching feature removed.
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.
