An unusual toy in the Beast Machines line, Che is less a character and more a play accessory. Che is a Beast Rider battle chariot, built by Cheetor (according to the on-pack bio) for firepower and speed. It doesn't transform, though its clawed arms can change configuration -- either forward for attack, or back for speed. The chariot is wind-up motorized and can fit most basic Maximal figures (ironically, most Beast Machines Cheetors are too big). Che was available in 2000 and re-released in 2001 with a different paint scheme.
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.
