Since the Action Masters didn't transform, they needed some assistance when it came to getting around. Included in the line were Action Master vehicles. So Prowl, one-time cop car, now drives a police motorcycle scaled to him. The Turbo Cycle (as it was called) transforms into a gun emplacement. This set was available in 1990.
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.
