From 1988, the next spark-shooting Sparkabot is Fizzle. He turns into a blue Baja buggy. This body design was used to make Blaze, a Europe-only release in Generation Two done in a translucent plastic and posted here.
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.
