Rounding out the 1986 Stunticons is the team leader, Motormaster. Like the other "Scramble City" type combiner teams released that year, four of the team-members were smaller vehicles sold individually on card, while the leader is a larger toy sold in a box. Motormaster turns into a Kenworth K100 Aerodyne truck with connected trailer. Not that scale ever made much sense in Transformers toys, but given that the cab of the truck turns into his feet, that means Motormaster would tower over Optimus Prime. That, not surprisingly, isn't how it appears in animated content, though Prime and Motormaster did spar for the king of the road title in truck mode at least once in the series. Motormaster also has a battle station mode that can connect to the larger city playsets released that year.
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.
