Megatron

For millions of years, Megatron has led fanatical legions of evil Decepticons on their war for conquest of the Universe. A living weapon with dozens of self-inflicted modifications made in the name of increased power and destructive capability, his only weakness is his single-minded desire for the enslavement of the Universe. His intellect, ego and talent for deception are second to none, and he rules his Decepticons with an iron-fisted combination of fear and force of personality. Driven by a nearly insane lust for power, Megatron managed not only to survive the catastrophic implosion of Unicron, but also to absorb much of his power. Now, wearing salvaged pieces of the ancient destroyer's armor, Megatron is awesomely powerful, and is determined to beat Optimus Prime and the Autobots to the lost Planet Keys.
