One of the earliest mail order exclusives in the Transformers line were the Powerdashers. For a measly three bucks and two "Robot Points" (proofs of purchase), you could send away for a Powerdasher and get one of three small, colorful, pull-back motor equipped transforming toys. They had zero story, character bios, or even names, and you couldn't choose which of the three you'd get. The jet Powerdasher would eventually be named Cromar in fiction.
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.
