Yesterday I posted Deathsaurus. Here are his BreastForce companions -- Tigerbreast and Eaglebreast -- who turn into his robotic chestplate. They also turn into handheld weapons, or armor for Deathsaurus' kaiju mode. They were released in Japan in 1989.
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.
