The Decepticon Ultra Pretender released in 1989 is Roadblock, the imposing ground forces commander. His inner robot turns into a small half-track tank. The inner robot can fit into a larger organic Pretender shell, which itself transforms into flying wind cruiser. All of that can fit into a non-transforming vehicular shell, a siege tank with battering ram.
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.
