In the Europe-only extension of Generation One that continued in 1993, there would appear the Aquaspeeders -- toy cars with water-squirting features and temperature-controlled color change plastic. Aquafend is an espionage expert who turns into a Baja buggy-style car. He's an Autobot, but his body became the basis for Jetstorm when this design appeared in Generation Two as a Decepticon.
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.
