The last of the numbered Robotmasters toys is two toys in one. "Reverse Convoy" is an Optimus Prime-version of the Generation 2-era Megatron M1 Abrams tank, done in blue with some retooling to give it a new Convoy-style head. But, it also has a Megatron head so the figure can double as "Rebirth Megatron." Reverse Convoy was available in Japan in 2004.
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.
