When Jazz brought Steve Guymo to the Autobot base, Optimus and the other Autobots realized that the Decepticons were behind the abduction of humans from airports across the nation. They were able to find the captive humans, whom the Decepticons were intending to ransom to the US government, and free them before engaging Starscream and his squad in battle. With the Decepticons defeated, the Autobots returned to base where Optimus thanked Steve for his help. Sun Raid (Listen 'n Play)
One more thought: LEGO is a Danish company. The fluctuations in the price of LEGO such as the big bump around 1985-7 in Figures 1 and 2 could be because of a change in exchange rates. The conversion rate between the Danish Kronor and the US$ went from over 10 in 83 and 84 to less than 7 in 86 and 87. LEGO might have been slow to respond to changes in exchange rates, leading to the temporary bump. If you’d like to share data we can redo your graphs in DKK.
Optimus was able to rally Autobot factions from across Cybertron to the cause and launch an all-out attack on Shockwave's fortress. He headed the assault himself, but broke rank when he saw the image of Shockwave blasting Ultra Magnus upon one of the many monitor screens planted around the Decepticon's headquarters. Optimus charged in to confront Shockwave, beating down all opposition along the way. Coming upon Shockwave's throne room, Prime was greeted by Ultra Magnus, who pointed him towards a secret passage through which Shockwave had absconded. Leaving his wounded brother to rest, Optimus barged into Shockwave's secret chambers, only to be overpowered and have the Matrix ripped from his chest. With it, Shockwave was finally able to activate Vector Sigma. Countdown to Extinction Stalling, Prime listened as Shockwave recounted the history of Cybertron, and eventually Ultra Magnus arrived, having recovered, to attack and defeat Shockwave. Prime and Grimlock helped him escape from the fortress as it crumbled to the ground. With Shockwave's defeat, the Autobots would now be able to start rebuilding Cybertron towards true peace... but Optimus remained troubled by Shockwave's motives; he recognized that Shockwave would not be urged to action by mere fancy. Optimus pondered what greater threat awaited Cybertron for Shockwave to so thoroughly plan for its arrival. Revelation The injuries Prime took in this conflict necessitated a prolonged restoration period in stasis. Both he and Ultra Magnus were tended to by Perceptor and Hoist as they recuperated. Generation 1 #0 Though Magnus recovered in due course, Optimus's systems had received a more severe shock due to the Matrix being forcefully removed from his frame. Thus, he needed additional time spent in recovery before he could reboot. Black Sunshine
Optimus and Prowl received message from Skyfire of a coal transport in Africa, and discovered Megatron was using human slaves. Megatron detonated his coal mines with the world's largest explosion, killing the humans and forging the world's largest diamond — that he would use to as a lens for a satellite to focus the Sun's beams, melting the Rocky Mountains! Prime ordered Skyfire to attack the satellite, and Ratchet to build a square mile panel of metal to deflect the beam, blowing the satellite up. Satellite of Doom The Decepticons attempted to drain the Prudhoe Bay oil reservoir, causing volcanic eruptions and Russia to approach America, accelerating tensions between the countries. Optimus ordered razon gas to be pumped into the reservoir, returning the oil below and raising the Decepticons' aquatic drill. When Continents Collide
Optimus Prime was one of only two Armada-theme figures in the otherwise Generation 1-centric Q-Robo Collection line of super deformed PVC figurines, the other being Armada Megatron. Like all the figures in the series, Prime featured articulation in the neck and shoulders, and was also available in a translucent colored plastic: as an Autobot, Optimus came in translucent red, but was also uniquely available in a golden metallic "pewter" variant as the wave's solitary rare chase figure. All Q-Robo figures were sold in sets of two, one full-color figure and one translucent one, blindpacked in a plastic capsule.
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.
