Released at retail in 2004 is a three-pack of Autobot Whirl and two pack-in Mini-Cons. Whirl is a character that dates back to 1985, and this new incarnation is a redeco of a 1992 toy, Rotorstorm, that turns into a high-tech helicopter. Since Rotorstorm was never designed to interact with Mini-Cons, the Armada-era redecoes don't really power up the larger toy like they typically would. Gunbarrel (top) turns into a multi-engined cargo plane, while Makeshift is a tilt-rotor helicopter.
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.
