So you take Silverbolt, Ironhide and Prowl and join them together through some of the most complex transformations yet seen in the toys, and you get this mighty Maximal, Magnaboss. His individual components were only available in a three-pack giftset, so no hunting or collecting required. Magnaboss was available at retail in 1997.
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.
