As leader of the Autobots, Prime headed up their mission to search for new sources of energy to revitalize the depleted Cybertron. Optimus vowed to Elita that he would return from his mission for her, but just before the launch of the Ark, Optimus was mistakenly led to believe that Elita was killed. Shortly after its launch, the Autobots' craft was attacked by the Decepticons' space cruiser, the Nemesis, and boarded by Megatron and the Decepticons. In the ensuing struggle, the G-forces of a nearby planet pulled both craft down, and the Autobots' ship crashed into a volcano, thrusting all the occupants into emergency stasis. Four million years later, in the Earth year 1984, a volcanic eruption jarred the ship's computer, Teletraan I, back to life. The computer reactivated the Decepticons, programming them with new Earth-based disguise modes. As a parting gesture, Starscream fired upon the Autobot ship, creating a landslide. The vibrations from that landslide knocked Prime into the path of the computer's restoration beam, restoring him to life, thus beginning the war anew on Earth.
If Optimus instead followed Prowl’s plan, he instructed his troops to transform into vehicle mode and play dead. The Decepticons, believing the Autobots’ ruse, disarmed themselves in order to carry out the Autobots’ “carcasses.” Now with the element of surprise against unarmed opponent, the Autobots Transformed and were able to easily defeat the evil robots.
The official international Transformers convention is BotCon, but other fan events include Auto Assembly and TransForce in the UK and past Transformers only events have included BotCon Japan, BotCon Europe and "OTFCC". The first larger Transformers convention in the Nordic countries is called "The NTFA Mini-Con", with official support from Hasbro Nordic, and was held by members of the NTFA - The Nordic TransFans Association, for the first time on November 3–4, 2007. The second NTFA convention with official support from Hasbro Nordic, now renamed "NordCon" (to avoid copyright problems with the name "Mini-Con") was held in Aalborg, Denmark from 19 June to 20 June 2010. It featured Simon Furman as a guest of honour. In 2011, NordCon and Auto Assembly joined forces to create a new convention called Auto Assembly Europe, which first took place in Uppsala, Sweden, in November 2011.
Optimus Prime returns in Transformers: Revenge of the Fallen. He leads the Autobots as part of NEST in hunting down the remaining Decepticons on Earth. He later engages in a battle with Starscream, Grindor, and a resurrected Megatron. Although Optimus manages to injure Starscream and kill Grindor, he is eventually impaled and killed by Megatron. However, Optimus is resurrected during the battle in Egypt by Sam using the Matrix of Leadership. He is then fused with the dead body of Jetfire, giving him an extremely powerful upgraded mode. After severely maiming Megatron, he kills The Fallen, forcing Megatron and Starscream to retreat. At the end of the film, Optimus thanks Sam for reviving him and again transmits a message to space, hoping to find more Autobots.
The price per minifigure has definitely gone up in the past 5 years. You used to be able to get 4 minifigs (along with some other stuff) at the $9.99 price point, now these are $12.99. And there are fewer minifigs in most $19.99, $29.99, etc. sets now. Lego Minifigures Series 1 was $1.99 each, subsequent series $2.99 each – I know it’s supply and demand, but it still feels kind of exploitative. I admit the cleverness of the builds keeps improving though.
This gold vacuum metallized (save for his black joints, which they were made out of unpaintable plastic) Protoform Optimus Prime figure was featured as a Lucky Draw giveaway (along side similarly gold vac-metal versions of Voyager class Optimus Prime and Protoform Starscream) in the December 2007 issue of TV Magazine. Released in 2008, only 5 pieces were made, making it one of the rarest Lucky Draw figures; the images at right represent the only known photographs of it.
