Next in the Spychanger assortment is R.E.V., whose name is an acronym standing for "Race Exertion Vehicle," apparently. He too inherits a mold from the 1995 GoBots assortment -- turning into a Lamborghini Diablo as Firecracker, Sideswipe and Optimus Prime also did before him. In Japan, R.E.V. was first released in 2000 as "Eagle Killer," before becoming known as R.E.V. in his 2001 US release.
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.
