Truly a valiant hero if ever there was one, Silverbolt is the most memorable of the Maximal Fuzors as he was afforded a prominent role in the Beast Wars animated series. A shining knight of a warrior, Silverbolt (no relation to the Generation One/Two SST jet) transforms into a winged wolf. He was available in 1998.
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.
