Scourge is a redeco of the Laser Rod incarnation of Optimus Prime from Generation Two. Whereas other redecos were quickly forgotten as quick methods to expand a set of products, Scourge had narrative sticking power because, hey, an evil twin of Optimus Prime is kind of irresistible. In Japan, he was known as Black Convoy. Within a few years of his release, other incarnations followed, most often taking existing Optimus Prime designs and painting them black. This Scourge made it to the US in 2002 as a Toys R Us exclusive.
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.
