Fitting for July 4th is a predominantly red, white and blue Autobot (I know, it's a grayscale illustration, but take my word for it). Here is the Energon incarnation of Ultra Magnus, which is a redeco of Overload from Armada. Ultra Magnus turns into a massive artillery-carrying trailer, which is pulled by Knock Out, the white truck packed with him who then forms Magnus' chest module in robot mode.
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.
