Striker is the next of the Beast Machine Dinobots on the roster. He's actually a redeco of Saberback, a Predacon from the Japanese Beast Wars Neo line. Striker is a Maximal, and turns into a stegosaurus. He was available in 2000.
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.
