Combined multiple different toy designs to get this concept for Megatron, mainly the Armada, WFC game, Bumblebee movie, and the Combiner Wars Armada Megatron as well as, sacrilegiously, Energon Scorponok.
The idea is that this version of Megatron IS Scorponok, or rather, Scorponok is the former persona he went by in the fighting pits of Kaon. He still kept his alt mode rather scorpion-like however.
