Finally, filling out the Metroplex playset is this illustration of Slammer, a tank made up of one of Metroplex's towers. And just for kicks, I paired Slammer with Roller, a pack-in that was included with the original Optimus Prime that fit in his trailer and otherwise was a small rolling scout. Slammer came out in 1986.
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.
