Moving onto some of the larger Decepticon toys available in the Classics line brings us to Astrotrain. This version of the original triple changer gets a much needed update to his train mode, turning into a Tsunami 800 bullet train (rather than a steam locomotive from the 30s!). His aerial mode is a space shuttle. Astrotrain was available at retail as part of the initial Classics assortment 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.
