Like yesterday's Optimus Primal, today's bonus drawing is a toy design originally planned for Beast Machines but was folded into the line's successor, Robots in Disguise, after the original line was cancelled. Appearing in 2002, this version of Megatron was a Kaybee Toys exclusive. He turns into an armored "spider tank," which is also a giant robot head if you remove the spider limbs, making Megatron Megabolt a Headmaster of sorts. In the Beast Machines series, Megatron was a Vehicon, hence the Vehicon logo. But the Robots in Disguise mythology didn't really have Vehicons, so this incarnation is both Predacon and Decepticon.
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.
