The five Terrorcons combine into the massive, monstrous warrior Abominus. As a "Scramble City" style combiner, all four of Abominus' limbs are interchangeable with any other Scramble City type. Abominus was available in a gift set in 1987, or could be assembled by collecting the Terrorcons individually. This drawing is from 2017,
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.
