Another repurposed Machine Wars design, Tow-Line was available in a two-pack with Decepticon Skyfire in 2001. He turns into a heavy duty Kenworth W900 wrecker tow truck. This design first surfaced in 1997 as Hoist and Hubcap. In Japan, this figure was released in 2000 as a "Flipchanger" named Wrecker Hook.
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.
