Starting in 2004, Takara began a line of modestly priced redecos akin the Universe series but also with a few new designs peppered into the mix as part of their brief Robotmasters series. Narrative support was light -- mostly through Japanese comics and prose fiction in magazines. The original molds tended to centered on very popular characters that spanned multiple media, like the first one of the line: G1 Convoy, better known to English-speaking audiences as Optimus Prime. This all new design is about the size of a typical action figure (4") and turns into a flat-nosed COE truck.
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.
