Part of the 2005 Micron Boosters collection bolstering the Galaxy Force toyline in Japan, Trigger turns into a tank. He is a redeco of Crumplezone, a Mini-Con originally packed with Cyclonus in the Armada line. He was later renamed Heavy Barrel in 2014 in a IDW Comics appearance.
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.
