The fourth and last of the Autorollers is Autostinger, which is a reuse and redeco of the Generation Two Decepticon, Dirtbag. This incarnation is a Predacon, though he still has the automatic transformation feature that lends the line its prefix. Autostinger turns into an earth mover-style dump truck. He was released in Japan in 1998.
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.
