Beginning a run of Railbots from Universe, a series of six Micromasters that turn into Japanese trains, released as a KB Toys exclusive in 2005. This design has been released before, and drawn here, in earlier Japanese incarnations, though Railspike marks his North American debut. Earlier iterations include Desire (1992) and Spark (1991). He turns into a Shinkansen 300.
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.
