Megatron, the leader of the Decepticons, is a master planner, constantly a step ahead of any opponent, prepared for anything. But his cold clinical nature is a front he struggles to keep up, as he's quick to anger and quicker to use excessive violence as his answer to any problem. He revels in violence and while his intentions on starting the war may have started out pure, he's become a monster. He is usually polite, but any opposition to his authority will be swiftly and painfully terminated.
