This spindly design was previously used for Prowl in the Robots in Disguise series, but is ported over to Universe with new red and white deco making him a "Fire Chief" Lamborghini Diablo. While that sounds like a description of Red Alert, trademark issues with that name meant it couldn't be used. Instead, Inferno got affixed to this character, a move that was reportedly a mistake too late to fix. There's an elaborate backstory somewhere in the margins that this Inferno is the same crazed ant character from Beast Wars, but I can't follow it. This Inferno came out 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.
