Next in the Firecon line is Sparkstalker, a fire-breathing kaiju-like monster with spark-shooting effects. Released in 1988, he was redecoed in transparent plastic that better showed off his spark-generating works in 1994, exclusively in Europe.
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.
