The 1992 and 1993 European and Canadian releases make up what is often called "Generation 1.5", much to the annoyance of many UK fans. These toys are similar in design to the Generation 2 Transformers, having lightpipe eyes, and pastel colors. The 1993 European figures used the G2 faction symbols which Hasbro UK designed because their licence on the G1 symbols had expired. The 1993 figures were repackaged for European G2 release in 1994, and three subgroup molds got used in the US G2 line.
Smash & Change Optimus Prime is a simple figure that transforms by "smashing" the rear end of the truck/the robot's feet into the ground. He features only elbow articulation in robot mode, and includes a sword accessory that can be held in his hand or mounted on the side of his truck mode. The handle on the rear of his truck mode is molded to emulate his Vector Shield.
Like the larger First Edition figure, you can actually separate the robot mode from his vehicle shell, displaying both of his modes at once... albeit unlike the First Edition figure, this tweak could sacrifice the even stability between those two separated figures. Some of the pieces like the legs/rear wheels are particularly difficult to separate.
In 2003, Transformers: Armada launched a pivotal new era in the toy line. After several lines of toys produced by one company or the other, Hasbro and Takara united to produce what was purported to be a single, identical line of Transformers for release worldwide. In tandem with this new endeavor, Armada signaled a new continuity in its accompanying animated series and a new focus in both the show and the toys on Mini-Cons, a new faction of Transformers. The Mini-Cons were much smaller robots (not much larger than humans) who were neutral in the Autobot/Decepticon fight, but due to their incredible power and abilities, were sought by both factions.
Convoy iPod Docking Bay pulls an all-white trailer of similar proportions to his vintage G1 load, with rear wheels and discreet propping feet so it can also stand alone. The trailer transforms (sorta), by rotating a substantial wedge of its full length 90 degrees, kinda like a rectangular Rubik's Cube. This exposes two small speakers and "reveals" an alcove (although a huge gap is still clearly evident in trailer mode) featuring an electronic port in which to plug an iPod or iPod nano, thus becoming a working iPod dock. The dock features three working buttons; power, volume up and volume down, as well as an Autobot sigil indicator light. Included is a wall-plugging (Japanese) A/C adaptor with a long lead that plugs into the reverse of the trailer.
The TakaraTomy "Autobot Alliance" release of this toy has some significant differences, including casting the red plastic in a darker shade, making his shin and wheel joints grey rather than Hasbro's bronze, painting the Matrix of Leadership silver, and swapping out the dual energon swords for battle hooks, similar to 2010's Leader class Optimus Prime. However, due to the Japanese release retaining the Hasbro packaging, the box still advertises the dual energon swords rather than the hooks. He retains the masked face used for the Hasbro release.
