I've drawn this design several times now: Guiledart, Triceradon (Beast Machines), Killer Punch, and Triceradon (Universe) just earlier this year. It's a favorite of mine, what with the triceratops head for an arm. This Triceradon, part of the Dinobots Walmart line, was packed with Slapper in 2003.
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.
