Here is God Ginrai, the combined form of Super Ginrai and God Bomber. Since the God Bomber component was only available in Japan in 1988, this particular powered up mode of the 1988 Power Master Optimus Prime toy was not possible in the US. At least, not until Apex Bomber showed up as a US release. This drawing is from 2019.
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.
