What Scourge was to Robots in Disguise, Nemesis Prime is to Armada -- an evil clone of Optimus Prime, and an all-black redeco of a previously released design. Like the Optimus Prime released earlier in the run, Nemesis Prime comes with a pack-in Mini-Con spaceship. Whereas Optimus had Over-run, Nemesis has Run-Over. Not exactly subtle.
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.
