Flip Sides is another e-HOBBY exclusive from Japan, dating from 2006 long after the idea of audiocassettes were an artifact. She is a redeco of the Eject/Rewind design from 1986, and came bundled with Twincast, the Japanese-exclusive version of Blaster from 1987. I've drawn her carrying Twincast here.
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.
