In the Armada story continuity, Optimus Prime is Autobot leader. In the first year of this new toyline, he got two toy incarnations -- the one depicted here is the smaller, more affordable of the two. Though not as large as one would think would better befit a leader, this version of Prime is very poseable. It turns into a truck of futuristic / Cybertronic / original design. His Mini-Con partner is Over-Run, who turns into a Cybertronic jet / starfighter. Over-Run can also turn into a hand-held laser gun for Prime.
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.
