Here's the first original design for Optimus Prime in Generation Two, released in 1994 after the previous year had a re-release of his original design. Unlike other versions, this one is a not a flat-faced semi truck, but rather a longer nosed Kenworth T600B truck. And in this version, the cab and the trailer together form the robot. In vehicle mode, the trailer doesn't separate, and holds a bellows-operated missile launcher play feature. Like a lot of Generation Two toys, the figure has its name printed on it somewhere.
The combined form of the Universe Micromaster Aerialbots is Superion, an amalgamation of six robots plus their pack-in accessories that serve as connectors, head, and extremities of the gestalt warrior. While in Japan, the original source of the design ( Sixwing , 1992) was available in a collected set, this combiner needed to be purchased one bot at a time in the 2007 Universe release.
