Optimus confronted his archenemy on the battlefield, though he had to knock Starscream aside to get to him first. Due to a nearby explosion that rocked the battlefield, Optimus nearly lost both his stance and his head when Megatron took advantage of the opening. But Optimus's quick reflexes allowed him to shift to vehicle mode and back, dodging Megatron's attack and striking back in the process. As the battle raged on, both combatants found themselves evenly matched. Then Ratchet contacted Optimus with dire news; the Decepticons had managed to abduct SARA! Fate
In the Autobot Campaign, Optimus Prime provides intelligence and missions to Bumblebee in his search for the Allspark. Eventually, the clues lead the Autobot to Sam Witwicky. After saving Sam from Barricade, Bumblebee finally completes preparations for the Autobots to arrive on Earth. Once on Earth and having informed the two teenagers of their mission, Prime and the Autobots are discovered by Sector 7. Optimus sends Jazz on a high-speed destruction distraction mission, then sends Ironhide to rescue Jazz from a double-threat posed by the government agents and various Decepticon scouts. When Bumblebee is captured, Prime transforms and chases the chopper which from which the small Autobot is tied. After a lengthy chase, Prime manages to catch the net, only to be thrown off by another Cybertronian meteor. As Bumblebee is carried away, Optimus promises he will not fail him again. Jazz informs him that the meteor is not an Autobot. Prime confronts the new threat, who turns out to be the Decepticon triplechanger Shockwave. The two battle it out across Tranquility before Optimus finally destroys him. During the battle, Optimus overhears Starscream's transmission revealing the location of the Allspark. Optimus then returns to an intel role as he guides Bumblebee in his mission to retrieve the Allspark from Hoover Dam. Unfortunately, the Decepticons manage to free Megatron, leading to the final battle in Mission City. As the Autobots battle it out with the Decepticons to protect Sam and the Allspark, things seem to take a turn for the worse as Megatron finally arrives. Before he can claim the Allspark, Optimus attacks him. Optimus defeats Megatron and leaves him on the ground, seemingly devoid of life. However, just as Sam is giving the Allspark to Optimus, Megatron awakens, leaping at Optimus with his chain-flail out, making one last attempt at defeating his adversary. Optimus grabs the chain, pulling Megatron in closer, and, with the Allspark clutched in his fist, delivers a punch through Megatron's spark, killing him. Optimus reflects on the losses and rewards of this battle, as the Autobots have a new home, but many were killed in the battle. The story ends with Optimus and the Autobots choosing to remain in Earth, proclaiming it as their new home.
In the "Transformers" film, the robots had more of an alien feel to them to fit the theme of an alien invasion. The robots (stated by Optimus Prime) in the film are actual sentient organisms and not just giant, mindless, and mechanical machines. The robots can also speak their own alien language sounding like what seems to be based on different pitches and frequencies. Alongside that, they gave them more alien features that probably wasn't mentioned in the comics or T.V. series such as a highly advanced exoskeleton, force field, and a special "alien meteoroid" mode which they transform into individually and arrive on earth in. The exoskeleton is a "self-regenerating metal" in which the aliens are composed of (stated in the film) that is the equivalent of living skin that heals itself.
This creation and expansion of the secondary market in conjunction with LEGO now marketing some of their products to an older audience has made the prices of some old sets increase exponentially. On the extreme range, there is the UCS Millennium Falcon that is selling new for upwards of $2,000 (and close to $1,500 USED!). It sold for $500 new in 2007. Even non-licensed sets can run a premium, such as the Cafe Corner that was one of the original modular buildings. It was $150 new and now it can sell for over $1,000.
Towering at only barely over two inches, this was actually not just the smallest movie-verse Optimus but even the smallest transformable figure of Optimus Prime for a while - ironically enough, being even slightly tinier than the Smallest Transforming Transformers Optimus Prime - that is, until he was later "out-tinied" by two other cute super deformed versions.
A BotCon 2012 exclusive purple redeco of the Deluxe "Generation 2" Optimus Prime figure from the Generations toy line, with the sword's blade molded in clear yellow. Much like the 2008 Voyager figure, this figure has painted-in "battle damage" effects. The right side of the hood has the words, "I shall stand...", while the left side says, "The rest shall fall."
Available only via mail-order through Dengeki Hobby magazine, this black and gray redeco of Optimus is one of four "Black Body" promotional Robot Masters toys made available through different outlets simultaneously. He came with his normal accessories (it is worth noting his axe was solid silver), plus a chromed-gold clear-red-plastic version of Psycho-Orb's "Calamity Defenser" solitarium shield.
Part of the first wave of Generations: Combiner Wars Voyager Class toys, this is a bigger, bulkier incarnation of Optimus Prime with a striking resemblance to Ginrai. He comes with two blasters which he holds via 5mm post. One of the guns is based on his trademark Ion Blaster, and both weapons store on the back of his vehicle mode as a makeshift engine block. His torso mode has several details that appear to be influenced by Energon Optimus Prime's super mode, including the head, chest, and thighs. In particular, the chest details are modeled after the Spark of Combination. He also features two pair of fake windows on his robot and gestalt chest halves. The combiner head can be used as a robot mode head if you're feeling silly.
