Dark Nitro Convoy is an evil clone of the Velocitron Autobot Override from the Cybertron series. He was exclusive to the Japanese incarnation of the line, Galaxy Force, and only available via a mail-in offer through TV Magazine. In Japan, Override was a male character (in the US, she was female) so his clone is also male. A redeco of Override, Dark Nitro Convoy turns into a sleek Velocitron race car. He was available in 2005.
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.
