The next Omnicon in the line is Signal Flare, a long range gunner and weapons specialist. He turns into a high tech, Cybertronian half-track artillery truck, with an enormous MASER cannon turret that becomes his arm in robot mode. His figure comes with a number of transparent red plastic additions -- shaped "Energon" weapons -- that can combine into a shield, or rotor blade, or other clever configurations. He was available in 2004.
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.
