The figure features newly redesigned hip ratchets to make both robot and combiner mode stable, which were also installed in both TakaraTomy's Motormaster, Grand Scourge, and a revision wave of Hasbro's Motormaster. The pegs that Legends Class Rodimus (or Blackjack) attach to have also been slightly modified to provide a tighter fit, making the latter toy much less prone to falling out.
Part of the first wave of Beast Hunters Series 3 Voyager Class toys, Optimus Prime is functionally an upsized copy of his Beast Hunters Series 3 Cyberverse toy, though with certain sculpted details based on his larger toys, the replacement of his ball joints with more robust ratchet joints, the addition of thigh swivels, and various deco differences. As a result, his complexity is lower than in his previous Voyager Class toys, but he ends up being much, much more massive.
Like many other modern toys, Optimus was designed with an alternate head sculpt (based on the mouthplate-less face as seen on the show) intended for a later retool, which was gang-molded with the original head. At least one specimen sporting the mouthplate-less head has been found at retail, although since this occurrence has seemingly been limited to an isolated incident, it can be assumed to be a manufacturing error rather than a genuine variant. The mouthplate-less head sculpt was eventually used officially for a later-wave redeco, Nightwatch Optimus Prime (see below).
In 2004 the LEGO group was in trouble. They were losing money and losing market share to other toys and entertainment products4. In order to address some fundamental issues in their business, they needed to cut costs. Leading up to this crisis, LEGO bricks had been adding new designs and colors without consideration for the cost to the business. LEGO went through a large reorganization and cut the production of unique elements in half, the variety of colors in half, and the number of suppliers by 80%. This, in addition to an increase in licensed sets and an expansion into video games, saved the LEGO Company.
While exploring Cybertron's hemisphere of darkness, Optimus Prime became severly damaged, and unable to return to the hemisphere of light. Having been able to send out one last message before his memory was badly damaged, Optimus found himself unable to distinguish friend from foe, and would join (or rejoin) whichever faction found him first. Optimus Prime Is Back
Originally, Optimus Prime was created as the leader of the Autobots, though it is unknown how he was created or his origins. In a possible future, Megatron was threatened by the existence of the Aerialbots and had Shockwave build a time machine to send them back in time to get rid of them. However, he only ended up changing history for the better. In the revised timeline, Optimus Prime began his life as a robot named Orion Pax, a mostly defenseless dock worker during the Golden Age of Cybertron nine million years ago, with a girlfriend named Ariel and a best friend named Dion. During this time, a new breed of robot with new flight capabilities appeared on the planet that Orion idolized. When Megatron, the leader of the new group of robots, approached him with inquiries about using one of the dock warehouses, Orion was swayed by Megatron. Both Orion and Ariel were severely wounded when Megatron and his forces attacked in order to claim the energy stored there. Searching for someone to help them, the time-displaced Aerialbots took Orion and Ariel to the ancient Autobot, Alpha Trion, who used them as the first subjects for the new reconstruction process he had developed involving rebuilding the frail Autobot frames into more battle-hardy configurations.
