When the legendary Energon Cube was lost to the reaches of space, Optimus Prime led a small team of Autobots in pursuit of it. The giant energy source crashed on Earth in the Japanese town of Hoshinochō, where it shattered into fragments that were scattered far and wide. Prime and the other Autobots set up a subterranean base below the Cube's impact crater and began their search for the shards, taking the forms of local vehicles to hide their activities. Despite their attempts at remaining unseen, glimpses of the Autobots only magnified the reputation the crash of the Cube (believed by humans to be a meteor) had given Hoshinochō: that of a hotbed of rumored alien and UFO activity, Japan's answer to America's Roswell. Kingdom of Giants
Optimus was eventually revived by the Autobots when they arrived to liberate Master from Decepticon hands. They found allies in the native Cyberdroids—those Optimus loyalists who had fought the Malignus insurgency. Autobots and Cyberdroids liberated the deposed triumvirate of Apex, Hi-Q, and Diac. Hoping to check the power-mad Galvatron and his three Cyberdroid allies, the Autobot leader was revived and binary-bonded himself to three Cyberdroids, including Surge, and Apex, who formed his head. Thus empowered, "Triple-Threat Prime" battled Galvatron and his forces across Master in a series of epic conflicts. The Autobots were unsuccessful and were forced to retreat.

However, Prime was encouraged to keep fighting by the cheers of a human boy named Junpei. Megatron, surprised at Prime's resilience, attempted to finish his foe off with his Tornado Axe attack. Prime countered with his Double Wheel-Torque Mega-Ton, which trumped Megatron's attack and injured the Decepticon badly. Megatron teleported back to his ship and left Earth's atmosphere, vowing to return.
Ultra Magnus is a redeco of the Diaclone "Powered Convoy" figure, itself a redeco and slight retool of "Battle Convoy", the toy that became the original Optimus Prime figure, sporting a new trailer. One of the last few Diaclone toys to be released in the Transformers toyline, Magnus was recolored from the original toy's dark blue, red and black color scheme into a more patriotic red, white and blue, though his chestplate, which was rendered white in his package art followed a more the blue color scheme of his shoulders. He transforms into a Freightliner COE, towing a car-carrier trailer capable of transporting up to four normal-sized Autobot cars. As with Optimus Prime, his cab transforms into a small robot, which can then combine with the trailer to form a "super robot", although all original Generation 1 fiction prior to the 21st century ignored this and simply rendered the super robot as Magnus's default robot form. To facilitate this combination, Magnus sports a slightly longer front axle than Prime, thereby creating tabs on either side of the cab that slide into grooves in the trailer to help lock the small robot into place. He is armed with a rifle sporting two handles that allow either of his robot modes to hold it, and two shoulder-mounted missile launchers, whose spring-loaded firing mechanism was removed for the Hasbro release of the figure.
After step 5, the instructions did not mention that you should fold back the shoulder panels to form the sleeper part until the 11th step. Care must be taken while transforming the legs: the small peg located on the lower leg can be snapped off due to the peg being slightly thick to accommodate with the hole. Also, take note that Optimus Prime cannot wield 5mm weapons with longer posts, as the way that his pinky finger is molded prevents the post from pegging down through his hands. Also, take note that the legs' sculpted small rectangle peg (the one that locks the robot mode legs in place) is prone to warping if care is not taken during transformation.
The first Generation 2 Optimus Prime toy was largely identical in sculpt to the original release. However, his trailer was cast in black plastic, with the original blue and silver striped sticker replaced with a red and silver one that had "Optimus" in large block letters on it. The trailer also featured a soundbox attachment with a sculpted Autobot symbol on the front. The soundbox could activate a truck engine noise, a laser gun sound effect and a (badly) garbled voice that said "I am Optimus Prime!". This soundbox could also be attached onto Optimus Prime's back and be used as a sort of backpack.
The TakaraTomy version, part of the first wave of Movie Advanced Series toys, is dubbed "Classic Optimus Prime", and opts for a deco closer to Prime's previous on-screen appearances, omitting the blue paint on his feet and hands to reveal the gray plastic underneath, and adding new paint details all over. Instead of painting it in clear light blue, his light-piping eyes is neutered with opaque light blue paint. In terms of quality control, at least one sample has missing it's silver paint on the head's left cheek.
Ten years after Unicron's defeat, Cybertron was seemimngly at peace, but Optimus still feared another attack from Unicron. Although the Autobot High Council dismissed his fears, a mental link with Primus confirmed that Unicron was still alive. Megatron's disembodied spark, trapped within the chaos-bringer, called out to Prime. Events overtook Prime as Unicron's four Horsemen, Rhinox, Airazor, Cheetor, and Terrorsaur, attacked Cybertron, devastating it. Prime's link with Primus allowed him to upgrade himself into his Energon form and drive them off.
Hot Rod would make his first IDW Publishing appearance in a Spotlight issue focusing on him. In this, he was shown to be newly promoted to command of a group of Autobots including Gizmo, Backbeat and Dealer, who had been sent to secure the Magnificence, a device of some sort that could predict the future. Getting past the guardians, Hot Rod was swapping it with a fake to prevent the Decepticons from getting their hands on it when a seeming Decepticon ambush wiped out his squad. Determined to rescue the only survivor, Dealer, Hot Rod staged a daring solo rescue mission that managed to rescue Dealer - unaware that he was really Doubledealer, a Decepticon spy sent by Banzaitron to retrieve the Magnificence and now out to find where Hot Rod had stashed it.
The Transformers Animated series was broadcast internationally in 2008 except in Japan, where it aired in 2010. This new series uses a very different art-style from the previous series. The Autobots and Decepticons, while fighting in space for possession of the Allspark, crash-landed onto a futuristic Earth and resume their battle after laying dormant for years. In addition to the Decepticons, the Autobots have to face the human villains as well. Classic characters such as Optimus Prime, Bumblebee, Prowl, Starscream, Megatron, Jazz and Ultra Magnus appear in this series.
In late 1993, Hasbro relaunched the Transformers franchise with the Generation 2 line, with production again largely being done by Takara. The subgroups concept was done away with for the first year, but there were no new molds or characters. Generation 2 re-used the molds for many of the characters from the 1984 and 1985 line, but with mostly different color schemes and finishes, as well as different weapons and accessories. Megatron's figure was released later on. As noted previously, Megatron's original alternate mode, or "transformation identity", was a handgun with attachments, but in Generation Two, this was changed to a tank due to safety and security concerns. Most of the 1994 figures were re-releases or recolors of European G1 releases.
