The reckless youth character from Beast Machines got the Happy Meal toy treatment: Nightscream is now far more properly scaled to interact with other toys rather than the enormous rendition of his character his main line toy got. He turns into a bat. He was available in 2000 at participating McDonalds.
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.
