The last of the individual Micromaster Constructicons is Hightower -- a stand-in for the classic Hook character whose name presumably was not available for trademark reasons. Hightower turns into a crane truck. He is a redeco of a 1992 Japan exclusive toy, Iron Lift. Hightower was initially available in 2004 as a KB Toys exclusive.
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.
