That’s actually a very big part, but I’d go lower than the $10 sets. The little tiny box sets with one minifig and some small vehicle or accessory that were $1-4 when I was growing up in the 80s now seem to be anywhere from $5 to $12 on the shelves. The cheapest of those are the sets that you could buy as a casual gift with pocket change in the 80s. Related to that, I’d like to see a metric that tracked the bottom price (both sticker price and adjusted price) of sets each year.
The box seems to have been created rather hastily from the Japanese original. It is roughly identical to the Tomy release, but with the Japanese text edited out... mostly. Random Japanese text remains floating in space on the top of the back panel and underneath the "Jetwing Optimus Prime" name on the front. Curiously, the left flap has been rewritten to eliminate mention of NEST and the jetpack's ability to detach, while the right flap has been (badly) edited to remove all mentions of MechTech.
Prime comes with all the accessories of his previous release, although his ever-changing ion blaster is now somewhat confusingly cast in blue plastic. He features one major additional accessory: an electronic display base sculpted with the image of the Matrix and the Autobot insignia. Pressing the insignia's crest triggers a series of electronic soundbytes, mostly quotes from the movie recited not by original actor Peter Cullen, but by Hasbro's in-house actor, Ron Hayden: "Autobots, transform and roll out!", "I want you to make a special run to Autobot City," "Megatron must be stopped!", "All we need is a little energon, and a lot of luck," and two samples of the classic transformation sound effect, one ascending, one descending.
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.
