Kicking off a run of Classic Pretenders: these are classic Transformers characters given new toy life as Pretender figures. As these all draw from the early runs, their new "upgraded" Pretender forms are actually smaller and less sophisticated than the toys that inspired them. First up is the classic Dinobot leader Grimlock (originally issued in 1985). As a Pretender, he still turns into a T-Rex (albeit a smaller one), and also has this space gladiator organic human shell. He was available in 1989.
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.
