More redecos from the Japanese incarnation of Beast Wars, though in this case these are Maximals in both their domestic and international releases. Bighorn is a redeco of Bonecrusher, and transforms into a bison. Scuba is another redeco of Claw Jaw, though the differences are minimal, and turns into a squid. Both were available separately in Japan in 1998.
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.
