Thundercracker rounds out the Decepticons from the Legends of Cybertron assortment available at retail, and like most of the others, he is a simplified version of a larger, more elaborate toy in the line. An homage to the G1 character of the same name (and update to an Armada character) this Thundercracker turns into a Sukhoi Su-37 jet fighter. He was available at retail in 2006.
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.
