The beasts are back! Backstop is an Autobot scout that turns into a robotic rhinoceros, but patches of pebbly skin on his armored hide recalls the techno-organic days of Beast Wars. Backstop hails from Animatron, the Jungle Planet, and comes equipped with the appropriate Cyber Planet Key that unlocks his spring-loaded ramming horn. Backstop was available in 2005, and in Japan was named Saidos.
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.
