The last of the 2007 Walmart-exclusive Classics Constructicon five-pack is Scavenger. He turns into a steam shovel, the huge earth-moving quarry type. Unlike the other Constructicons in the set, he is not duplicated with a redeco'ed partner. Still, he is a redeco of Energon Steamhammer, since the whole set is a redeco of the Energon Construction Team.
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.
