The fourth of five Aerialbots is Slingshot, who turns into a Harrier jump jet. The Generation Two incarnation of Slingshot, released in 1994, is notorious among collectors for suffering from "Gold Plastic Syndrome." The particular mix of plastic used for most of his body grows extremely brittle with age, and it's rare to find an example of this toy intact.
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.
