As previously mentioned, the Cybertron Leader toy of Optimus Prime could further combine with certain other Autobots to make his super mode even more super. In this case, the feline warrior Leobreaker turns into a slasher arm mode that replaces Prime's regular right arm. Wing Saber replaces the flight pack gained from Prime's trailer to become chest armor, shoulder cannons and wings. And, to finish off the figure, Optimus Prime here is wielding Vector Prime's sword.
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.
