The crowning achievement of Kinetic Solutions Incorporated, the man-made drone code-named Galvatron was originally intended for use in the United States military, hunting down and dispatching any rogue Transformers that had evaded human capture.
Reverse-engineered from the scavenged remains of Megatron, the drone adopted many of his features during its construction. In reality, however, Megatron's consciousness had survived his destruction, and bit by bit the Decepticon leader fed his captors the technical information they required. In time, KSI had unwittingly built him a brand new body ripe for the taking. Galvatron's lack of a true spark makes him almost invincible, as does his ability to split apart into a cloud of Transformium and avoid taking damage. With the fearsome mind of Megatron and this powerful new body, Galvatron conspires to turn KSI's technology against its creators, forging a new Decepticon army under his command. [Source: TFwiki]
