Jack -- no relation to the Micron Booster also named Jack -- is the Japanese redeco of Runway. This design has been used many times, with this particular incarnation being exclusive to Takara's Legends of the Microns line in 2003. Jack (later known as Jackknife in Fan Club fiction) turns into a Boeing Sonic Cruiser concept jet and is finished with some translucent plastic parts.
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.
