In the Cybertron animated series, Megatron took the primal rage of Autobot Leobreaker and used it to clone an evil Decepticon, Nemesis Breaker, who in toy-form is basically a redeco of the Leobreaker toy. The hefty toy comes with electronic sound effects and turns into a mechanical lion. He can also turn into a clawed arm that can combine with larger robots, just like Leobreaker. Nemesis Breaker was available in 2005.
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.
