The Blastcharge that shows up in the 2005 Universe line is a redeco of the toy that debuted in the 2000 Beast Machines line, but rather than be a Vehicon, he's a Decepticon in this incarnation. He's rendered in darker hues, with a skull-like deco on the hood of his vehicle mode, which is a six wheeled combat vehicle.
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.
