The last of the Happy Meal Maximals from 1996 is this odd little guy with the unlikely name of Under-3. It's not really his name -- it's an age indicator in the Happy Meal toy -- he's suitable for kids under three years of age. Without any other identifying names to go with, Transformers fans simply called him that, and it stuck. More recently unearthed development art reveals that this was meant to be an incarnation of Optimus Prime. The toy itself is simply a hinged locket shaped like a lion's head that opens up to reveal a sculpted robot body on the interior.
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.
