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.
Came with the Mini-Con Sparkplug. Could combine with Armada Jetfire (and its repaints) and/or Armada Overload (and its repaints). The trailer could convert into a base for Mini-Cons. In Japan a gold chrome edition of this toy was released as a Lucky Draw special. With its trailer the vehicle mode of this toy bears a great resemblance to G1 Star Convoy. According to the Armada video game Armada Optimus Prime is supposed to be 22 feet 10 inches tall (696 cm tall) and the toy is 17.5 cm tall. So that's a scale of 1:40.
The second War Within Optimus Prime toy in the Titanium series, but also the first official transforming toy from the War Within series. Personally designed by comic artist Don Figueroa (who created much of the War Within comic designs), Optimus Prime transforms into a Cybertronic truck. He is armed with a silver painted Ion blaster, on which the word "DON" can be clearly seen sculpted into the body.
At some point, Optimus Prime disappeared under mysterious circumstances, and Ultra Magnus arrived from Cybertron to take his place as Autobot commander. Galvatron's Air Attack Prime eventually returned many centuries later, now sporting a Powermaster body, and rejoined the Transformers' war after it had moved from Earth to the alien planet of Nebulos.
A black and red version of the First Edition deluxe Optimus Prime could be seen in the San Diego Comic-Con 2011 Transformers slide show, inside a mock-up of the wearable Matrix of Leadership package done for the convention that year. This figure was presumably a test-shot, as it seems to share plastic colors with Generations Sky Shadow (who was, coincidentally, first revealed at that same Comic-Con).
A redeco of Cybertronian Optimus Prime with a translucent red front section, additional (painted) "scratched paint" details, some red paint highlights either omitted or changed to yellow and additional yellow circuitry pattern detailing reminiscent of the jammed abilities/mode lock/EMP effect from the War for Cybertron game, available in a Toys"R"Us-exclusive three-pack with redecos of Cybertronian Megatron and Cybertronian Bumblebee.
Over the course of the next twenty years, the Decepticons succeeded in seizing control of all of Cybertron, forcing the Autobots to operate from their new city on Earth and two bases on Cybertron's moons. In the Earth year 2005, Prime, stationed on Moonbase One, dispatched troops to Earth to acquire energy for an upcoming strike on Cybertron. The Decepticons, however, got wind of the plan and used the shuttle run to attack Autobot City. A distress call summoned Prime and support troops to Earth. In the fearsome, ensuing, epic battle with Megatron, Optimus Prime sustained fatal wounds, but not before turning the tide of battle and forcing the Decepticons to flee. Despite the efforts of Perceptor, Optimus Prime went offline after passing the Matrix and role of leader to Ultra Magnus. His last words were "Until that day... 'till all are one." The Matrix later fell into the hands of Galvatron, a recreated Megatron, and was finally taken back by the young Autobot Hot Rod, who became Rodimus Prime after bearing the Matrix. In season 3, set a year after the events in The Transformers: The Movie, Rodimus was the new leader of the Autobots.
When Sideswipe was accused and convicted of destroying the Nova Suspension Bridge, Optimus was infuriated that one of his own Autobots could commit such a heinous act. Optimus was tasked to hunt down and deactivate Sideswipe, though the task proved to be easy as Sideswipe did not run, hide or resist. After Optimus had deactivated Sideswipe, he was approached by Prowl, who pointed out that Sideswipe's actions made little sense, as he had committed the crime in broad daylight before many witnesses. Agreeing that the Decepticons might be behind the situation, Optimus allowed Prowl to take a team of Autobots to Carob Island to clear Sideswipe's name while Optimus and Jazz stayed behind to continue working on human/Autobot relations. Prowl returned with evidence that it was indeed a Decepticon-controlled clone of Sideswipe that had committed the crime. Optimus then presumably reactivated Sideswipe when his name was cleared.
