A cocky stupid second in command of the decepticons, megatron is the leader of the decepticons and their enemy is the autobots. Whenever megatron either dies or is wounded starscream always tries to take command of the decepticons. (Megatron always comes back. 99% chance) their species are transformers (cybertronians) from the planet cybertron. They can transform into almost anything electronic or so on, megatron transforms into a gun, a tank, or a fighter jet. Starscream transforms into a jet.
