It's Magmatron... again. I posted him not too long ago, as part of the Beast Wars Neo line, but he's back as part of Beast Machines. It's the same toy as the Japanese release, with some modifications to bring the pointy bits into US safety standards. The insignia on the toy are still that of Predacons, even though the character is a Maximal in its US release. It was a Target exclusive in 2000. Magmatron consists of three individual dinosaur components: a gigantosaur (his lower body), an elasmosaur (his upper body) and a quetzalcoatlus (his winged back and head).
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.
