The largest Starscream incarnation to date, his Machine Wars version is based on a 1992 European exclusive named Skyquake. Arriving in 1997 alongside Megatron, this change in their relative sizes is sure to wreak havoc on their particular power dynamics. Starscream turns into a Cybertronic jet that has a passing resemblance to an SR-71 Blackbird, but is more sci-fi than military accurate. This concludes the Machine Wars assortment that was briefly available exclusively at Kay-Bee toys.
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.
