This is Cog, the incarnation of the character that was included in the Grand Maximus set, a different coloring than the Fortress Maximus version. And while the Fort Max Cog was the combined form of Gasket and Grommet (two small service vehicles), the Grand Max Cog is the combined form of Onomisu and Koka.
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.
