Modes come and go, but Mirage will always be drawn to high end professional race cars. Here is the classic Autobot, now in his Machine Wars incarnation. He turns into a Penske PC-18 Indycar, and was originally slated as a Generation Two release before that line's cancellation. He saw the light of day as a Kay-Bee Toys Exclusive in 1997.
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.
