Megatron is a character from the Transformers franchise created by toy company Hasbro in 1984, based on a design by japanese toy company takara. The original Megatron was the leader and warlord of the Decepticons, a fictional faction of sentient self-configuring modular extraterrestrial robotic lifeforms from the planet Cybertron. He serves as the nemesis of the Autobot leader Optimus Prime. In most incarnations, after meeting his demise, usually at Optimus' hands, Megatron would be resurrected as Galvatron.
