Also from Japan is Battle Gaia, the combined form of the Operation Combination gift-set that collected a uniquely redecoed set of Combaticons as new characters. Being based on the same designs as the original Combaticons, Battle Gaia is basically a differently colored version of Bruticus. He was available in Japan in 1992. 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.
