The 20th toy in the Robotmasters line is a two-pack of dueling Cyberjet designs. It's Autobot Delta Seeker (a redeco of Skyjack the F-117A Nighthawk stealth fighter) versus X-Gunner (a redeco of Space Case the Sukhoi Su-47 Berket jet). The set was available in Japan in 2004.
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.
