Megatron is a fictional character from the Transformers franchise created by American toy company Hasbro in 1984, based on a design by Japanese toy company Takara. Usually portrayed as a villain, Megatron is the supreme leader of the Decepticons, a faction of war mongering Transformers who seek to conquer their home planet of Cybertron and the rest of the known universe. A cruel and power hungry leader, Megatron leads the Decepticons with an iron fist and has little to no tolerance for failure. While some Decepticons under his command have challenged and attempted to take his place as leader (most often Starscream), Megatron maintains his power and authority over the Decepticons by proving himself as the most powerful in their ranks. He serves as the nemesis of the Autobot leader Optimus P
